It may be because you have painted it from a wrong function. From which function did u call the DrawText().

Drawings are not saved by Windows. Instead, when the window needs to be repainted, a WM_PAINT message is sent to it so that it can draw itself. So, if you don't put your drawing code into the OnPaint function, then it will be lost the next time your window is repainted.

Hello,
I have an application which is on the verge of completion .In there I have about 24 classes derived from MFCs and 15 generic classes apart from the 2 classes that are MainFrm and app class .
Now while editing any of my programs if I press the ENTER key the the cursor takes about 20 secs to come to the next line.
This doesn't happen with Word ,Excel.So concluded that there must be some problem with the my application rather the memory of my computer.
I should now reduce the size of my application.
But how should I do that?Or Is there any other problem?
Regards
Pritha

Which application ?? You mean the IDE (visual studio), or your own application ? What are you doing there when you press enter ?
Did you try to see what is taking so much time ?

When I am in my Workspace typing or editing my programs at that time the cursor takes 20 secs to come to the next line if an ENTER is pressed.

Close the IDE and delete the .ncb and .opt file in the project folder. Then restart the msdev.

.ncb file is the intellisense database file.
The .opt file contains the build logs.

First Check your file are added to you project. if it is already added, try deleting the "clw" file in the project folder.

Your class is derived from CDialog? 
lahom wrote: icouldnt find my own class in the drop down list..
You mean in the dropdown list of class wizard?
if so, I think your Project's classWizard information might be corrupted. It often happens. You just take your project directory, then delete - *.clw. Now load the project in visual studio and press Ctrl+W. It will take the class wizard.
Since the classWizard info is deleted, it will show a dialog and ask whether to regenerate it. Press yes and it will show a dialog to select source files. Add All your source files. I hope, now you can see your new dialog class in class wizard. 
Does this solves? or your problem is something else?
Regards,
Jijo.

Hello,
I made an application with a few classes developed by me.Then I made a dll for the classes which act as the base classes for developing my application.
But when I develop an application with this dll the application gives Unhandled Exception .If I develop an application using my base classes then the application is developed and works fine.
Is there something that must be missing while making the dll?
I went through the steps mentioned in a book for making the dll and the dll is been made.
Regards,
Pritha

Please provide the details of exception. if you press Ctrl+C in the Messagebox, the entire message will be copied to clipboard. FYI.

Your class depends on MFC? did you forget to add AFX_MANAGE_STATE(AfxGetStaticModuleState( )); as the first line of all exported functions? Just possibilities. Provide more info, then only we help in isolating the issue.

Jijo.

Hello,
Thanks
I have not mentioned this
AFX_MANAGE_STATE(AfxGetStaticModuleState.Where should I write this ?
While making the dll I have written AFX_EXT_CLASS in the declaration of the class.
I am getting the following Unhandled exception.
Unhandled exception in DllClient.exe(MFC42D.DLL):0xC0000005:Access Violation

As the first line of all exported functions. See details here http://msdn.microsoft.com/en-us/library/ba9d5yh5(VS.80).aspx[^]and technical note here - http://msdn.microsoft.com/en-us/library/ft1t4bbc(VS.80).aspx[^]
I stress the point, it might be the reason since we don't have see the code. BTW, could you post the code snippet, which throws the exception?
prithaa wrote: While making the dll I have written AFX_EXT_CLASS in the declaration of the class.
AFX_EXT_CLASS is to make the class exportable. It expands to __declspec(dllexport).
