I am calling a stored procedure with cfscript, but when I add the addProcResult method to the call, ColdFusion returns the error The specified key, result, does not exist in the structure. Removing the method fixes the error and doesn't effect the results, but I still would like to know why the error appeared. Using <cfstoredproc> and <cfprocparam> doesn't generate the error. I am running CF9. My code is below.
spService = new storedProc();
spService.setDatasource("mydb");
spService.setProcedure("someSP");
spService.setUsername("TaskRunner");
spService.setPassword("password");
spService.addProcResult(name="result",resultset=1);
spService.execute();
You'll get this error if your stored procedure actually doesn't return a resultset (perhaps it returns an output parameter--or nothing at all).
Simply remove the call to .addProcResult(), and you'll be fine.

I have an error that seems to be associated with <cfscript> db operation
// traffic tracking
myQry = new Query();
myQry.setSQL("INSERT INTO dbo.Traffic (Circuit, Fuseaction, IP_hash) VALUES (:circuit, :fuseaction, :ip_hash)");
myQry.addParam(name="circuit", value="#listfirst(rc.fuseaction, '.')#", cfsqltype="CF_SQL_VARCHAR");
myQry.addParam(name="fuseaction", value="#listlast(rc.fuseaction, '.')#", cfsqltype="CF_SQL_VARCHAR");
myQry.addParam(name="ip_hash", value="#cgi.remote_addr#", cfsqltype="CF_SQL_VARCHAR");
myQry.execute();
The really strange thing is, it looks like the operation completed. What kind of a error is this?
Short answer: It's probably a scoping issue. Try:
var myQry = new Query();
Long-winded waffley answer:
I'd call it an Adobe-developers-being-useless kind of error.
If you look at line 460 of that file, you'll see the error is due to a failure of StructFind to find the query name in the variables scope, and the reason it's appearing in debug input is because there's a try/catch with type any surrounding it. The same functionality could be achieved without causing/catching an error by replacing the try/catch with <cfif StructKeyExists(variables,tagAttributes['name']) > which is basic CFML knowledge, and certainly something a developer of the CF product should know!
The same code still exists in the CF10 version of base.cfc, so you may or not feel like submitting it as a bug in Adobe's CF bugbase - though it's unlikely they'll fix it for CF9 (and uncertain whether they'll feel CF10 is worth the effort either).
However, that would only be side-stepping the issue of the variable not existing, not addressing the real issue of why it doesn't actually exist. Given that the debug info shows the query is successfully executing, and the query code is basically right above that line (starts at line 442), it shouldn't be a repeated/common error, but it may be due to your myQry variable not being scoped, and thus it could be colliding with another variable also called myQry (or even the same var from a separate call to the function) which is happening between the execution of the new Query() and .execute() lines, and thus causing the original query to not be there when the StructFind looks for it.
The solution is to put the keyword var before the first use of myQry which will place it in the local scope for that function - something that should be done for all variables that are only for use within an instance of a function, (otherwise they are placed in the variables scope of the component/request that the function exists within).
I'm calling Script::Compile() and it returns me an empty handle as result. I've traced into this method and finally found that
i::Handle<i::SharedFunctionInfo> result = i::Compiler::Compile(str, ....
is returning the empty handle. That means compilation error.
But does anyone know is there a way to get error message from compuler in this case to get know where error has occured?
Take a look at the ReportException function in the Shell example. You need to use a v8::TryCatch to capture the exception and report on the error.
I am trying to use the Google geocoder to do a reverse-geocoder lookup. I am running the exact same command on 8 values, and I am only having an error on two of them, which has me confused as one of the failing values is identical to one of the working values. (The 'working' values aren't really working- they still return a value of undefined from the 'formatted_address' field, but they aren't throwing errors). The command that I am running is as follows:
geocoder.geocode({latLng: new google.maps.LatLng(machineList[i].y, machineList[i].x)}, function(results, status) { address = results[0]; });
I am receiving a type error from Javascript, claiming that results is null. I'm not sure why this is happening. Any ideas?
Well, it turns out this was a timing issue. The geocode() command was taking longer to complete for certain locations than for others, which caused the value to show up as null. I ended up eliminating the problem by moving all the subsequent code into the callback function (I hadn't done this earlier because the whole thing is running inside of a loop, and I was having some difficulty getting it to pass in the iterator as a parameter). Now everything seems to be working well and the locations are showing up as they should.

mfc
if CHttpConnection::OpenRequest returns a null what can I use to get the internet error.
The mfc artical doesn't say what a bad responce looks like. I just said it returns a handle to a CHttpFile.
Did you see what is the error code returned by GetLastError() ? Get the error code and perform a error lookup (Tools->Error Lookup) to get the description about the code. Normally you will get the exact reason for the failure using this.
I am very new to SSL , Actually I would say I know nothing about it.
I am using the method "SSL_CTX_new" to create an SSL_CTX object. The method returns null.The documentation says I can check the error stack in order to get the cause for this.
So I have the function "int SSL_get_error(SSL *s,int ret_code)" which (as I understand) I have to use in order to get the error message. the documentation of the method says nothing about the first parameter of the function. It only says that the second ("ret") parameter should be equal to the return code from the failed operation which can be any of the following :
SSL_connect(), SSL_accept(), SSL_do_handshake(), SSL_read(), SSL_peek(), or SSL_write()
So now I am having two problems. The first is that I didn't use any of those functions but rather use SSL_CTX_new that doesn't return any kind of return code (it returns a pointer to SSX_CTX object) So i don't know what to put as the "ret" parameter. The second problem is that I don't know what does the first parameter mean and what should I put there , because the doc says nothing about it.
You need a valid context to create the SSL object.
Since you can't create a context you can't use SSL_get_error.
Try using ERR_print_errors to see what's gone wrong
#include "openssl/err.h"
...
SSL_CTX * ctx = SSL_CTX_new(....);
if(!ctx) {
ERR_print_errors_fp(stderr);
//throw or return an error
}
I just had a read of the SSL docs. If you need to programatically get the error code / error string you should use the ERR_get_error and ERR_error_string functions.
Have a look here and here
As per http://www.mail-archive.com/openssl-users#openssl.org/msg51543.html, you may be missing a call to SSL_library_init(). Adding this before the SSL_CTX_NEW(..) call fixed the NULL value problem for me.
