Debbuging a DLL

hgr_iwf — Mon, 25 May 2009 17:19:44 GMT

Hello!

Is it possible to debug a dll or generate a core dump file in windows? I call the Fortran-dll from IDL (interactive data language). I need it because my written dll crashes anywhere and anytime.

I hope, that someone can help me.

Thanks, Hannes

Yes. Right click on your DLL project and select Properties, Debugging. In the path to execute, put the path to the EXE that calls your DLL. Set a breakpoint in your DLL routine(s) and then press F5 to start debugging. Your program will load, and when it calls the DLL the breakpoint will be hit.

Make sure that the DLL being invoked is the Debug build result.

Thanks for your help, but I get following error message, when I press F5 to start debugging:
"Visual Studio cannot debug because a debug target has not been specified."

Is it correct, when I set in the Debugging Properties of my DLL project in the Field "Working Directory" my path where I copied my dll into the folder where my exe-file is located? And I only have to copy the debug dll in the folder where the exe-file is located?

Have I to do other settings?

Thanks, Hannes

Hannes,

I haven't tried this, but I think you would be better using the debug version of the DLL insitu in the folder where it was created through Visual Studio. Add this folder to your PATH so that the .exe file can find it.

I think this will work better than trying to move the DLL, or elase VS won't know where it (and other files it needs) are.

Regards,

David

Sorry, I misremembered the field to set. It is "Command" under Debugging. Put the full path to the executable there.

Is it only possible to debug it with an exe-file? The problem is that I cannot generate an exe-file. I only can execute my source code with the programming environment of IDL.

kind regards,
Hannes

Put in the path to the EXE that starts the IDL environment.
