When the assertion fires, it tells you the line number and file of the offending statement. That should give you a big hint.

Thanks David,
I looked at that and it refers to line 31 of some MFC file. When i press retry on the debug assertation window it refers to getAfxAppName() at line 31 of that file with a yellow arrow in the call stack window. Also in the call stack window is a green arrow referring to line 22 of the code that i posted which is the 'CInternetSession InternetSession;' declaration, and refers to a $E4() method. There is also a window that comes up showing an 'Unhandled Exception' which i'm guessing is what the $E4() is. Any ideas on what to do with this exception?

It would help to also know the name of the file.
Are you using Visual Studio v6 or .Net?

Hi,
Just initialize the CInternetSession Variable with a name.
For example, CInternetSession x("MY APPLICATION");
That should solve your problem.

Hi,
Attempting to use PlaySound and sndPlaySound on a Win CE PocketPC. The API call returns to say it is a happy chappy and all is well, but I certainly don't get the specified .wav file played  ! The file name is correct etc etc
Any idea's?
Interestingly, when I try and play .wav file from Windows explorer they don't sound either.... probably a clue there..!
Thanks

AppWizard is used once to create the initial project. After that, you can manually add classes to the project via ClassWizard. To add controls to the dialog template(s), select the ResourceView tab in the Workspace window, expand the Dialog item and double-click on the dialog resource you want to add controls to. Make sense?

Hi
Does anyone know how to get the list of USB devices connected in machine through c++
thanx in advance
|
|
|
|
|
We use sdiGetClassDevs, which takes the GUID for various USB devices, and then SdiEnumDeviceInterfaces on that to get each one. Then SdiGetDeviceInterfaceDetail will give more info. There are other functions in the same area that might be interesting to you.
Unfortunatly our compiler is too old to support the calling conventions used the actuall functions, so we have some wrappers. (there are historical reasons why we don't have a better compiler) You will need to figure out what the windows names for those functions are from those names. As I recall a search MSDN for those names will turn something up.

As always, programs change. My application started as a stand alone app. In the latest change, the request was made to ad COM support with my app becoming the server. The client can open my dialog boxes. It took some time, but it is up and running. The displaying of dialog boxes and most of the error messages get sent to the new client.
The problem is now: On DDV_ the validation does a display of a messagebox using AfxMessageBox() this goes directly to the active childframe of my app. The other error messages were replaced by ::MessageBox() where I can specify the window handle.
How must I tackle this sneeky little problem? Any advice appreciated.

AfxMessageBox() calls the virtual function CWinApp::DoMessageBox().
Override it and call ::MessageBox with the parameters you want.

Hi,
I've writting a program which drives an imaging system through visual c++.
I would like to display some datas in a real-time graph.
Maybe someone could help me to find the code tu use.
Thanks a lot,
W.

This is a little vague. By real time graph do you mean oscilloscope?
Perhaps searching for such on this site would help.

You can draw your "graph-field" (rectangles, lines, ...) and upon the field a polyline which represents the values.
update the polyline at intervals. (redraw the field and the polyline)
check out drawing tutorials etc...
good luck!

You need to handle the WM_DROPFILES message, after you've registered the application as a dropped-files recipient using DragAcceptFiles().

Try DragQueryFile().

Hi,
I am presently working on a multithreaded VC++ application which consists of 3 threads each accessing the same database.
Would it be more efficient to use 3 different connection objects or just a single connection object in this case?
Looking forward to your reply..
Thanks,
Mahadevan
