C++ Change Print Queue Owner - c++

I want to know if it is possible to change the “Owner” name that is visible when you bring up the print queue to view the queued printer documents. I have a Windows Service that receives a document from a user and sends it a Windows printer, and the Owner is always the name of the user that logged into the workstation where the Service is running. I would like to change the “Owner” to something else, and this would be done in a C++ Windows DLL that the Windows Service loads and uses.

Thanks for the suggestion, Thomas. I should have mentioned my research, but it was long and empty. MSDN has a SetJob function which can take 1 of 4 structures (pJob = JOB_INFO_1…JOB_INFO_4). JOB_INFO_1, 2, and 4 have an LPSTR pUserName that appears to be what can be used to change the owner of the print job (Owner?). However, in the remarks section of SetJob it says:
“The following members of a JOB_INFO_1, JOB_INFO_2, or JOB_INFO_4 structure are ignored on a call to SetJob: JobId, pPrinterName, pMachineName, pUserName, pDrivername, Size, Submitted, Time, and TotalPages.”
And JOB_INFO_3 does not have this field in it. Nice.
I did not see any other functions that could maybe do this. Can you point me to something specific that I can research more? Or that is known to work? Thanks.

I'm not sure why MSDN says those fields are ignored. I change pUserName, pDocument, pStatus using SetJob with JOB_INFO_1 and it works perfectly.
Just be sure to set Position to JOB_POSITION_UNSPECIFIED.

OTRS Webservice as Requestor Test

I'm new to OTRS (3.2) and also new to PERL but I have been given the task of setting up OTRS so that it will make a call to our remote webservice so a record can be created on our end when a ticket is set as "Closed".
I set up various dynamic fields so the customer service rep can fill in additional data that will be passed into the webservice call along with ticket details.
I couldn't get the webservice call to trigger when the ticket was "Closed" but I did get it to trigger when the "priority" was changed so I'm just using that now to test the webservice.
I'm just using the Test.pm and TestSimple.pm files that were included with OTRS.
When I look at the Debugger for the Webserice, I can see that the calls were being made:
$VAR1 = {
'TicketID' => '6'
};
My webservice currently just has one method "create" which just returns true for testing.
however I get the following from the Test.pm
"Got no TicketNumber (2014-09-02 09:20:42, error)"
and the following from the TestSimple.pm
"Error in SOAP call: 404 Not Found at /TARGET/SHARE/var/otrs/Kernel/GenericInterface/Transport/HTTP/SOAP.pm line 578 (2014-09-02 09:20:43, error)
I've spent countless hours on Google but couldn't find anything on this. All I could find is code for the Test.pm and TestSimple.pm but nothing really helpful to help me create a custom invoker for my needs and configure the webservice in OTRS to get it to work.
Does anyone have any sample invokers that I can look at to see how to set it up?
Basically I need to pass the ticket information along with my custom dynamic fields to my webservice. From there I can create the record on my end and do whatever processing.
I'm not sure how to setup the Invoker to pass the necessary ticket fields and dynamic fields and how to make it call a specific method in my remote webservice.
I guess getting the Test.pm and TestSimple.pm to work is the first step then I can modify those for my needs. I have not used PERL at all so any help is greatly appreciated.
I'm also struggling with similar set of requirements too. I've also never programmed in PERL, but I can tell you at least that the "Got no TicketNumber" in the Test.pm is right from the PrepareRequest method, there you can see this block of code:
# we need a TicketNumber
if ( !IsStringWithData( $Param{Data}->{TicketNumber} ) ) {
return $Self->{DebuggerObject}->Error( Summary => 'Got no TicketNumber' );
}
You should change all references to TicketNumber to TicketID, or remove the validation whatsoever (also there is mapping to ReturnedData variable).
Invoking specific methods on your WS interface is quite simple (but poorly documented). The Invoker name that you specify in the "OTRS as requester" section of web service configuration corresponds to the WS method that will be called. So if you have WS interface with a method called "create" just name the Invoker "create" too.
As far as the gathering of dynamic field goes, can't help you on that one yet, sorry.
Cheers

Get rid of security message Outlook

I'm writing an application that needs to access to Outlook address book, however, every time I launch it a warning message is shown saying that an application is trying to access to your adress book. I've noticed this behaviour only with the machines where no antivirus is installed. How to get rid of this message?
Here is a part of the code I use to retreive some emails related informations
CApplication l_application;
l_application.CreateDispatch("Outlook.Application");
CNameSpace l_namespace = l_application.GetNamespace(_T("MAPI"));
CMAPIFolder l_mapiFolder = l_namespace.GetDefaultFolder(olFolderInbox);
CItems l_items = l_mapiFolder.GetItems();
m_mailItem = l_items.GetLast();
m_mailItem.Save();
//Get infos (mail's size, from, to, conversation topic...)
CApplication, CNameSpace, CItems are generated automatically, and m_mailItem is a CMailItem object.
See http://www.outlookcode.com/article.aspx?id=52 for a list of your options. Essentially you can either make sure an up-to-date antivirus app is installed or use Redemption (I am its author).

Cannot get onSession Start to fire in Mura

I have a script :
<cfscript>
gf = createObject('component','com.general');
gf.checkIpBlocked();
</cfscript>
that I want to fire onSessionStart.
I added an onSessionStart to /siteID/includes/themes/myTheme/eventHandler.cfc. But the session start NEVER fires. I know there is something managing sessions because of I open the admin, login then close the browser, re-open it I am forced to login again.
If I set a session variable close the browser and and the session.testVar never goes away and seems to hold the initial value for a very long time.
I am not trying to manage mura users or anything I am just trying to set a session variable the first time in a "session". In a typical application.cfc this is easy.
Any insight is appreciated.
Unfortunately, that's a bug. However, one thing to keep in mind is that onSiteSessionStart is unreliable since it only fires when a siteID is defined within the request. For example, if you were to go to the admin and be asked to login your session will have started and there would have been no siteID.
For now I would try using onSiteRequestStart to param the variable instead.
function onSiteRequestStart($){
param name="session.ipChecked" default=false;
if(!session.ipChecked){
var gf = createObject('component','com.general');
gf.checkIpBlocked();
session.ipChecked=true;
}
}
In regard to our documentation we have three Mura 6 books available both printed and digital downloads from Lulu
And are also working to create a systematic way to post the contents of those books on our support site which we are hoping to complete by MuraCon on 9/30. So that the all of our documentation will stay update and in sync.
The Mura docs state that the application events are actually onGlobalSessionStart and/or onSiteSessionStart.
Application Events
onApplicationLoad onSiteSessionStart
onGlobalSessionStart onSiteSessionEnd
onSiteMissingTemplate onSiteError
onGlobalError onBeforeAutoUpdate
onAfterAutoUpdate onGlobalThreatDetect
Note that Events that begin with onGlobal are defined on a per-Mura
instance basis.

Can I programmatically use the OneNote printer driver?

I have a system service that handles print requests, and given a printer name from the user, attaches a DC to that printer. It starts a document, ends it, and detatches.
m_PrinterDC.CreateDC (L"WINSPOOL", _printerName.c_str(), NULL, NULL)
m_DC.Attach(m_hprinter)
m_DC.StartDoc(...)
...
mDc.TextOut(...)
...
m_DC.EndDoc()
m_DC.Detatch()
This works fine for normal printers, but when using the "Print to OneNote" functionality (driver name 'Send To OneNote 2010') it doesn't seem to work. I would like to avoid custom logic just for this feature; ideally all printers would work regardless. Any thoughts what might be going wrong? I've tried updating the printer security settings to include Print rights for group everyone; not sure what else to try.
Unfortunately, I have to guess some points, because you seem to avoid detailed description of error condition.
First, if you check all return values are success, just it may be a problem about onenote itself. Check the condition of onenote by printing using other programmes.
Second, did you check if _printerName is exact? If some of users are using other language OS, the driver name, 'Send To OneNote 2010' will be different or depending on version. Of course, if you check all return values of function calls, it recorded in your log file. However, I'm worrying about you used exact printer name by using 'EnumPrinters'.

I hope this helps you a little.

CF extended components suddenly stop working

We have a set of Coldfusion applications that all extended various parts of an application base. I'll provide a bit of code and then explain the issues we are having and see if anyone can shed light on the best way to trouble shoot this:
In our "OnRequestStart" in the app.cfc we have the following line to initiate a user:
if(!structKeyExists(SESSION, 'user'))
SESSION.user = CreateObject("component","cfcs.ds_user");
Then in the ds_user.cfc we call it like so:
component extends="cas.cas_user" displayname="basic_user"{
The application and all its parts run just like they should. However, in a seeming random manner after a while, the application will crash and I have to restart ColdFusion Service to get it running again. The error I get is:
Could not find the ColdFusion component or interface cas.cas_user.
So, for whatever reason after a while, my application decides it cannot find the path to the parent component. The mapping for that cfc is in the application.cfc at the top as so:
THIS.mappings["/cas"] = "#ReplaceNoCase(currpath,ListToArray(THIS.name,'_')[1],'cas30')#assets\cfcs\";
I want to be sure to say this, the application works perfectly as designed for a random amount of time and then it cannot find the parent component and will not find it again until I restart the ColdFusion Service on the server.
I figure this is somehow a memory leak or something, but I have no idea where to start looking to troubleshoot the issue. We have 6 or so other applications that are extended in the same way and work fine and never crash, but this one does.
EDIT: To be more clear on the mappings. Our applications are located:
root.com/app1
root.com/app2
We created mappings to grab cfcs from app2 while in app1 using the method above. The method, while I believe sort of strange, does work in all of our applications.
EDIT: The correct mappings that display for a while are:
/cfcs - D:\www\app1\assets\cfcs
/templates - D:\www\app1\assets\templates
/cas - D:\www\app2\assets\cfcs
/common - D:\www\app3\assets\common_elements
However once the Application goes in "crashed mode", the dump reveals the mappings are as follows:
/cfcs - D:\www\app1\assets\cfcs
/templates - D:\www\app1\assets\templates
/cas - D:\www\app1\assets\cfcs
/common - D:\www\app1\assets\common_elements
And here is how those mappings are defined at the start of the Application.cfc:
currpath = GetDirectoryFromPath(GetCurrentTemplatePath());
THIS.mappings["/templates"] = "#currpath#assets\templates";
THIS.mappings["/cfcs"] = "#currpath#assets\cfcs";
THIS.mappings["/common"] = "#ReplaceNoCase(currpath,ListToArray(THIS.name,'_')[1],'gum')#assets\common_elements\";
THIS.mappings["/cas"] = "#ReplaceNoCase(currpath,ListToArray(THIS.name,'_')[1],'cas30')#assets\cfcs\";
THIS.name = digisign_CAAAFACBFDFFE or
name_var = (arrayLen(meta_array) >= 2) ? meta_array[arrayLen(meta_array) - 1] & '_' : 'root_';
THIS.name = name_var & right(reReplace(hash(getCurrentTemplatePath()), "[^a-zA-Z]","","all"), 64 - len(name_var));
Where could it be failing. It seems the replace statement isn't working and therefore the appname in the path is not being changed from app1 to app2 when setting the mappings. is it possible this is related to this error we are currently working through: http://forums.adobe.com/message/4657868#4657868 We have yet to apply the Update 4 patch on production. However this problem we believe was happening before CF10. And while we have this issue, it only cropped up recently. This application in question has been crashing like this for a long time.
EDIT:
1. I guess when I say "crash" I mean the application gets into a state, where it will not declare the mappings correctly until I restart Coldfusion. I assume the error in our code causes the crash.
2.This is usually where the issue occurs, when doing this check of the SESSION.user var. I believe it has happened as well, it decides it cannot find our datasource. This is rare.
3. At first I thought yes, but actually no, not that many. Throughout our apps we have several names for common mappings. cas common cfcs templates etc. However D:\www\cas is where the application domain.com/cas30 is located. However a legacy version of that app is located at domain.com/cas. The mapping /cas should go to D:\www\cas30\assets\cfcs and works.
4.We have a dev setup and this never happens. (I assumed it was a load issue which is why it doesn't happen on dev). However, our dev environment is structred as so:
D:\www\deva\app1
D:\www\deva\app2
D:\www\devb\app1
D:\www\devb\app2
What we do (which I think is stupid) is we have a file located not in the same dir as the current app. This file is called application_base.cfc. All of the application.cfcs in the other applications extend from this application_base.cfc. They are not extended from other Application.cfc files. (hope that makes sense) In application_base is a init, onrequeststart, and an onerror. I'll post the App.cfc below. Also some setting are read from XML files both in the application base (to determine environment stuff) and at the application level. However we thought that might be causing the issue so the previous developer removed the xml file at the application level.
6.Yes. I'll post the app.cfc and the appbase.cfc so you can view both.
By reinitialize you mean call onapplicationstart or something. Not that I know of.
A few applications we have do:
currpath = GetDirectoryFromPath(GetCurrentTemplatePath());
app_path = ListToArray(currpath,'\');
THIS.name = app_path[ArrayLen(app_path)];
This one does:
meta_array = ListToArray(GetMetaData(this).name,'.');
name_var = (arrayLen(meta_array) >= 2) ? meta_array[arrayLen(meta_array) - 1] & '_' : 'root_';
THIS.name = name_var & right(reReplace(hash(getCurrentTemplatePath()), "[^a-zA-Z]","","all"), 64 - len(name_var));
A few others do this as well. Not sure if it was two different developers or something, but that is the way it is.
Once the app fails, it fails until I restart coldfusion. The app requires login from the domain.com/app page, so (not saying it cant change from request to request) but the request location is always the same where it's failing.
God I wish it wasn't this complex. I recently pulled our current CMS off of alot of this crazy stuff, but we have 7 or 8 applications that are so intertwined with each other and designed to work in dev/prod environments with different paths, its sometimes hard to tell what I can remove and what I can't.
I thought I tried dumping the applicationname from our error handler, but I thought it didn't work unless passed in. I passed through the mappings so I could see them which is how I know digisign is not changing to cas30 like it should in "crash" mode.
I think all the dynamic mappings were so the original developer could just use the same app.cfc template without changing anything. He liked to do stuff like var a = (b) ? (a-c) ? a-f+b : (a+b) ? d : d; : a; h; crap with no comments so it sometimes hard to just read the damn code let alone debug it.
EDIT
I feel like this issue and stackoverflow.com/q/14300915/1229594 issue may be related. I've posted some more details here as well: forums.adobe.com/message/5022377#5022377
First things first: why are you initialising session-oriented stuff in onREQUESTStart()? If you inited that in onSessionStart(), you'd not need to check for its existence every request, which - whilst trivial - is unnecessary overhead, and is simply the wrong code in the wrong place.
Secondly... you quote your error, but don't say where it's happening. Is it happening in that line in onRequestStart()?
If so, do me a favour: put a try/catch around it, and within that write the value of this.mappings to a log file, as well as the value of currPath. How is the value of that variable being derived, btw?
That said, I think if you just put that session.user init code in the right place, it'll solve your problem.
NB: frame this problem as almost certainly not a memory leak (ie: ColdFusion's fault), but your code doing something you did not anticipate (so... err... your fault ;-). This will help focus better on finding the problem. I'm not having a go at you, but "where is my code wrong" is a better approach than "it's probably something else". And more likely to be correct ;-)
Oh... and what version of CF are you on?
Take a look at this and see if it's relevant to your problem.
https://github.com/Mach-II/Mach-II-Framework/wiki/Application-Specific-Mapping-Workaround
If not, then it could have something to do with application specific mappings of the same name, on the same CF server, with those applications having different application names.
Some questions:
Are you assuming the crash is being caused by the code error, or that the code error is occurring because of the crash?
Is the instantiation of the session user the only line of code that you see these path errors?
Do you have any physical directories in your app that have the same name as the mapping names?
Does this occur in any other environments (dev/test)? Is this a clustered environment?
Are there multiple Application.cfc files extending this same Application.cfc?
Is there any code that is directly calling Application.cfc methods?
Are there any bits of code that cause the application to reinitialize itself?
What is determining the meta_array that is being used to derive the application name?
A few observations:
It seems to me that the application name is getting changed or that some other application is overwriting with the same name. This doesn't seem far-fetched as there's an awful lot of dynamic naming going on here. Starting with the application name, it's dependent on the current template's physical location, which could be different from request to request, depending on how the app routes requests. If the current template varies, the application name will vary, and cause the other app-specific mappings to change, which would cause a cascading effect to all the other mappings that use the app name to determine the physical location of those mappings.
Which begs the question: Why is all this dynamic evaluation of the application name and mapping locations even necessary? Can it be simplified or hard-coded? Can you instead use a server mapping? If it doesn't have to be this complex, simplifying it to its barest essentials will help troubleshooting and may clear up the issue entirely.
Finally, can you verify that the application name during normal operation is the same application name being referenced when the errors are occurring?
If they are different, then something is causing the application to execute within a different context (see my initial questions above for clues). A sudden change in the application name would invalidate any existing sessions and force the session user instantiation code to re-run. And because the user component paths are based in part on the application name, the paths may no longer be correct.
But if the application names are the same between normal operation and crash mode, then most likely the currpath variable is being affected by some part of the application being executed in a different physical path than expected. Since currpath is directly used in determining the rest of the mappings, that could certainly explain why an unexpected path could cause the component to go missing.
Because there are so many variables going into deriving these names, you would be well served to log those variables during normal operation and during crash mode. You'll want to see
GetCurrentTemplatePath()
GetDirectoryFromPath(GetCurrentTemplatePath())
THIS.name
meta_array
THIS.mappings
I suspect you'll find something significantly different in these variables when operating normally and when the crash/errors are occurring, and that difference should lead you closer to the answer.
