I'm writing an extension to MFC app with use of ZMQ (zmq.hpp). When I'm trying to unload my DLL from the app, the zmq_ctx_destroy() function hangs forever.
I have found a similar issue but there is no answer.
I've tried to debug it and found out that it stops in function zmq::thread_t::stop() on the first line:
DWORD rc = WaitForSingleObject (descriptor, INFINITE);
It hung even without sending anything. Simplified code looks like this:
zmq::context_t context(1);
zmq::socket_t socket(context, ZMQ_REQ);
socket.connect(ENDPOINT.c_str());
Socket and context destroyed when leaving scope.
Call Stack:

The MFC app has a mechanism to run specifically created DLLs. This DLL is based on CWinApp, all DLL-specific initialization code in the InitInstance member function and termination code in ExitInstance. So this JIRA issue should not be the case.
After a couple of days I found out that the app also relies on sockets as ZMQ. So at the end of its life ZMQ context was waiting for closing of all opened sockets in the process, but MFC app continues to use its opened sockets. That was the reason why zmq_ctx_destroy() function hangs forever.
Solution for cases like this one (when app uses sockets as well and you need to add some functionality based on ZMQ).
Create a new process. This process will create a ZMQ context and send/receive all messages. Data from dll could be passed to that process via Windows messages or shared memory.
I am trying to read a file. The call is from VB to CPP dll.
Here is my sample code snippet
VB CALL
Private Sub ReadFile(...)
On Error GoTo Problem
Dim errorString As String
Sample.ReadFile basepath, filename, register, errorString
GoTo Completed
Problem:
WriteToLogFile basepath + filename + errorString //error string contains the formatted hresult message from cpp dll
My CPP function:
HRESULT ReadFile(...)
{
hr= actualread(...)
if(FAILED(hr)
{
return E_FAIL //
}
If I change E_FAIL to ERROR_FILE_NOT_FOUND VB is not logging the error message.
The E_FAIL message description is Unspecified error. Which does not help the user much.
It logs E_POINTER,E_HANDLE etc anything that starts with E_ not with ERROR_
COM specifies which values in a HRESULT are treated as errors, and which aren't. To quote from Structure of COM Error Codes:
The high-order bit in the HRESULT or SCODE indicates whether the return value represents success or failure. If set to 0, SEVERITY_SUCCESS, the value indicates success. If set to 1, SEVERITY_ERROR, it indicates failure.
The E_ constants are designed to be used this way, and have appropriate values to ensure they get treated as errors. The ERROR_ constants are not, they are meant for a different convention for reporting errors.
As WhozCraig pointed out in the comments, there is a HRESULT_FROM_WIN32 function you can use to convert a Win32 error code to a HRESULT.
Decoding Errors
-2147220978 style numbers are 32 bit signed integers, convert to hex with calculator.
Windows errors (smallish numbers) and COM HResults (typically, but with exceptions, start with an 8 as in 0x80040154) are defined in WinError.h, except 8007nnnn where you look up the Window error number that it contains.
As a general rule Windows errors are less than 65,535 (0xFFFF). Errors starting 0x80000001 are Component Object Model (COM) HResults. Errors starting 0xC0000001 are NTStatus results. Errors starting 0xD0000001 are also NTStatus values returned in a HResult.
WinError - Returned from Windows API Calls
HResult - Returned from COM calls
NTStatus - Returned from kernel and some API calls also return when
encountering a kernel error.
NTStatus errors (typically but not always start with an C as in 0xC0000022) are defined in NTStatus.h.
.h files are the best source because it includes the symbolic name of the error which can give clues such as the source of the error. FormatMessage doesn't give the symbolic name only the description.
You get these files by downloading the Platform SDK (it's gigabytes)

If you just want the two files I have them on my skydrive so I can reference them anywhere I go.

Note internet errors (12,000 - 12,999) are windows errors but are specified in wininet.h also available above.
There are errors defined in other .h files. But 99% are in the three above.
Structure of HResults and NTStatus Codes
The most significant bit in HResults, and the two most significant bits in NTStatus are set on error. Hence Hresults start 8 on error and NTStatus starts C on Error. The next 14 or 15 bits are reserved and some specify the facility - what area the error is in. This is the third and fourth number when reading hex. EG 0xnn07nnnn - An HResult facility code 7 is a normal Windows' error (returned from a COM program - hence it's returned as a HResult). Facility codes are defined in Winerror.h for HResults and NTStatus.h for NTStatus codes. They are different.
To Decode 0x8003nnnn Errors
HResults with facility code 3 means the HResult contains OLE Structured Storage errors (0x0 to 0xff). These are the same as Dos error codes. These don't seem to be in Windows' header files and the list of codes is at the end of this post.
To Decode 0x8004nnnn Errors
HResults with facility code 4 means the HResult contains OLE errors (0x0 to 0x1ff) while the rest of the range (0x200 onwards) is component specific errors so 20e from one component will have a different meaning to 20e from another component.
This is why the source of the error is extra important for errors above 0x80040200.
To Decode 0x8007nnnn Errors
HResults with facility code 7 means the HResult contains a Windows' error code. You have to look up the Windows' error code not the HResult.
To decode 0x80070002. The 0x means it's a hexadecimal number, the 8 means error, the first 7 means it a windows error, and the rest of the number, 2, is the actual Windows error.
To look up the error we need it in decimal format. Start Calculator (Start - All Programs - Accessories - Calculator) and choose View menu - Scientific, then View menu - Hex. Enter 2. Then View menu - Decimal. It will say 2.
Start a Command Prompt (Start - All Programs - Accessories - Command Prompt) and type
net helpmsg 2
and it will say
The system cannot find the file specified.
or look it up in winerror.h
//
// MessageId: ERROR_FILE_NOT_FOUND
//
// MessageText:
//
// The system cannot find the file specified.
//
#define ERROR_FILE_NOT_FOUND 2L
To Decode 0x8019nnnn Errors
HResults with facility 0x19 are HTTP errors. Codes under 16,384 (0x4000) are the same as HTTP errors, eg HTTP status 404: The requested URL does not exist on the server is 0x80190194 (0x194 = 404). Codes 16,384 and higher are BITS specific.
To Decode 0xDnnnnnnn Errors
HResults starting 0xD are an HResult with a NTStatus value in it. Just cange the lead D to a C and treat as an NTStatus (Hresult = NTStatus OR 10000000).

In a Windows Application I created I am attempting to run a batch file that points to a .vbs. It runs the vbs script but it does not modify the registry as needed. However, if I run the batch file manually it functions properly. Does anyone have any insight as to what could be the issue? I thought it was permissions but why would it matter if I manually click on the batch file or if my program opens it? Regardless, I have modified the batch file to try to run as admin but nothing online seems to work.
It says nowhere that CreateProcess can run batch files. As batch files aren't programs CreateProcess can't do anything with it. CMD.exe executes batch files.
YOU WOULD HAVE KNOWN THIS BY TESTING THE RETURN VALUE and by reading the Docs
From Help
Return Value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Also from Help
To run a batch file, you must start the command interpreter; set lpApplicationName to cmd.exe and set lpCommandLine to the name of the batch file.
This is What You are Doing Wrong
1. You have a bizzare program design.
Any program can prompt for user input and write to the registry. You are writing a program that will have at least four different ways of writing the registry (.NET, WSH, WMI, API). Then you run a batch that has two ways of writing the registry (WMI and reg.exe). Then a vbs file with two ways (WMI, WSH).
2. You do not test for errors.
You must test for errors. The only person with access to the error is YOU. Errors say what happened. You must fix the error or crash. And there is no point asking without the error number, error source, what it was trying to do, and the parameters.
Errors are to be expected. Users do delete or move files for example.
3. You must read the documentation
It has to be open while you program. It explains what you need to tell it for it to behave in certain ways. Just typing random commands (as many here do - they are invalid of course) OR typing random parameters (as you are) doesn't work. If you don't read them you don't know what they mean.
4. Playing helpless
When you get told the answer, you go and look everything up in the documentation, and then google it.
You not reply with a pathetic "it didn't work". You post the error number, error source, what it was trying to do, and the parameters.
This is how to decode errors

I have this legacy application which I've been trying to get up and running.
It has some dependencies on an old DirectX SDK version which can only be installed on WinXP (or prior) so I used a virtual machine of mine and successfully built the application. However, due to limitations of the virtual graphics hardware the application is not rendering its graphics correctly, but that was just expected. The rest of the application (UI-interaction and such) seems to work just fine on the virtual machine (32-bit Windows XP).
When I try to to run the applcation on my physical machine, 64-bit Windows 7, it hangs in an early state. I used some debug output to track down exactly where it hangs, and it's when CDialog::Create is called for creating a modeless dialog.
I finally tried to start it on my laptop, 32-bit Windows 8.1, and it worked. I'm thinking that it should have something to do with x86 vs x64, but of course I cannot be sure.
Has anyone come across something similar? I've googled a lot on CDialog::Create hanging, and found some interesting threads, but everything looks correct in code, and well, it runs, but only on 32-bit machines.
Update:
I managed to build the application in VS2010 by removing a bunch of code. When I debug the application the callstack shows that it hangs on the CreateDialogIndirect call in CWnd::CreateDlgIndirect.
I found a thread regarding this, but it didn't solve anything, AfxOleInit is being called.
This discussion sounds more interesting but I haven't gotten around to try the proposed solution yet.
Update 2:
Setting the DEP to AlwaysOff didn't change anything.

Update 3
The application is usually started using a C# launcher application (to be able to select user profiles and other startup settings) and starting it this way it hangs. Also, starting it from the file explorer (or command prompt) it hangs. BUT, if I start it directly from VS2010 using F5, it runs...
SOLVED
I updated my graphics driver, and everything works great.
I updated my graphics driver, and everything works great.
I have a DirectX9 application that sporadically runs into a hang in WM_WINDOWPOSCHANGED. The hang occurs only rarely when alt+tabbing into and out of fullscreen exclusive mode.
The application is hung because the main window message processing thread is stuck at WaitForSingleObject() in the DefWindowProc handler. Other threads we have created are operating normally.

I am wondering what Windows is waiting for here. DirectX is created and owned by a separate thread, but that thread is not stuck. We seem to be handling things correctly for lost devices (freeing up video memory resources and calling Reset()).
If anyone has ideas on why windows is hanging here, I would appreciate it.
Usually when I see this problem it is because SetWindowPos() needs to be called after setting the window style with a SetWindowLong() function. Changes will not be updated until SetWindowPos() is called, as detailed here:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633591%28v=vs.85%29.aspx
It does not always seem to crash without calling SetWindowPos(), but will sometimes. I am not sure why the result is usually so sporadic. Either way the results will not update without that call.
