Run LabWindows/CVI DLL from Visual studio 2013 Express

[JeroenCroes]

Hello all,

I have an older LabWindows/CVI DLL which I call from VS 2013 express.

However, I want to be able to debug the DLL by setting breakpoints in e.g. the initialize.

This is what I've done:

In the LabWindows/CVI proj, specify the executable and command line to visual studio exe "D:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\WDExpress.exe".

Run the  LabWindows/CVI proj, visual studio opens, select the VS proj, run it and go the to initilize DLL call (LabWindows/CVI DLL), which has breakpoints.

Now when the step in VS is executed the breakpoint in LabWindows/CVI is not hit and VS just moves to the next step.

Is there a reason why the breakpoint in the initialize function doesn't get hit?

When specifying in LabWindows/CVI the exe that the VS projects generates iso the VS exe, hits the breakpoints in LabWindows/CVI... 

So how can I set the LabWindows/CVI proj so it looks at the VS generated exe iso the VS exe itself?

LabWindows/CVI 2013 SP 2, Visual studio 2013 express, both proj debug mode. 

Thanks in advance.

Hello Jeroen,

I don't understand what you want to accomplish.

If you specify the executable and command line to visual studio exe ("D:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\WDExpress.exe") you are attempting to debug VC, which is not what you want.

You should specify the exe that loads the LabWindows/CVI dll which is the exe generated by VC. But I think you already did this, this is what I understand by

I don't understand exactly what the problem is.

Hello Constantin,

My goal is to debug my visual studio proj and LabWindows/CVI DLL at the same time by stepping through the code in VS and in LabWindows/CVI.

I want to be able to step through VS code that calls the LabWindows/CVI DLL and hit a breakpoint in the LabWindows/CVI proj and step through it in the LabWindows/CVI method.

Trying to attach LabWindows/CVI to the exe that VS generated is something that I'm unable to. LabWindows/CVI gives an error that it's unable to attach.

Hello Jeroen,

You can't do that because you can't be attached with 2 debuggers to the same process in the same time.

You have to do one at a time.

You can detach from one environment and attach with the other one but you have to add some waiting in your code to have time to do this.

From LabWindows/CVI you can attach from Run->Attach to Process/Detach from process menu and from VC with Debug->Attach to Process/Detach All
