OnHelpInfo() is not called when you click on the 'Help' button (ID_HELP). (at least in my apps it is not)

It depends on how you handle the ID_HELP. I remember that for some reason we had to forward the call to CWinApp (which in turn called OnHelpInfo indirectly) - sorry, no source code at hand, can't be more specific  Maybe it was related to help on property pages.

Do you know any kind of class or something that can put a nice texture
as background (dialog background). I've use the 'CxShadeButton' class (found here on CodeProject)
and want preferably a class of the same button class!
Can you help me!?? OFCOURSE!

Just draw it onto the background in your OnPaint handler.

I have tried to search scientific way of handling retutn key on many
discussion boards and websites but no use.
I have dialog box with two edit boxes. One edit box accepts number.
When user enters number and hits enter (Carriage Return) key it
should display the corresponding data to entered record number
in another edit box.
Since it is single line edit box the enter key will be grabbed by dialog
box and I have no way to intercept enter.
Then I tried
This
In my Edit Control class I added following...
UINT CQSmartEditCtrl::OnGetDlgCode()
{
UINT code = CEdit::OnGetDlgCode();
code |= DLGC_WANTMESSAGE;
return code;
}// OnGetDlgCode
and
void CQSmartEditCtrl::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
if(nChar == 13 ) // Return Key
{
AfxMessageBox("Need to Display Data");
}
CEdit::OnKeyDown(nChar, nRepCnt, nFlags);
}
But now I don't know how to handle displaying of Data because I need to send
notification to dialog that it is time to display record. How to achieve this.
Also, I have question is there any alternative way to get Return Key from within
edit box which is scientific way
Regards,

In OnKeyDown handler call CWnd::GetParent and cast the result to proper type - pointer to your dialog class. Then call appropriate method (the one that displays data) using the pointer.

Thanks Tomas...
It helped me. Now I have one more question
UINT CQSmartEditCtrl::OnGetDlgCode()
{
UINT code = CEdit::OnGetDlgCode();
code |= DLGC_WANTMESSAGE;
return code;
}// OnGetDlgCode
This function is making Edit Ctrl to intercept all messages
including TAB and ESC
How to skip these messages?

Win2000 DDK SP1 have two constant in ntddk.h:
- PULONG_PTR (in struct _KDPC for exemple)
- ULONG_PTR
These two constants are unknown and undefine

These types are defined in basetsd.h
PULONG_PTR, which is a pointer to a ULONG_PTR.
PULONG_PTR is a pointer that is itself 32 bits for 32-bit Windows and 64 bits for 64-bit Windows. It points to an unsigned integer, ULONG_PTR, that is 32 bits for 32-bit Windows and 64 bits for 64-bit Windows
My copy of this faile is from the platform sdk. so make sure it is part of your project's path.
#if !defined(_W64)
#if !defined(__midl) && (defined(_X86_) || defined(_M_IX86)) && _MSC_VER >= 1300
#define _W64 __w64
#else
#define _W64
#endif
#endif
#if ( 501 < __midl )
typedef [public] __int3264 INT_PTR, *PINT_PTR;
typedef [public] unsigned __int3264 UINT_PTR, *PUINT_PTR;
typedef [public] __int3264 LONG_PTR, *PLONG_PTR;

#else // midl64

Hope that helps.

hey ... quicky question
in the docs it says one must call CWinApp::HideApplication() before calling CWinApp::CloseAllDocuments() but i don't cos i don't want the app to close ... it seems to work ok but does anyone know if there is some terrible screw up happening down in the depths that just hasn't showed itself yet by not calling CWinApp::HideApplication() first ??
answers / hints appreciated

I don't think you're going to screw something without HideApplication - if many your app is MDI and many MDI child windows are open you'll see them closing one by one. Just remember that calling CloseAllDocuments will destroy all docs *without* saving modified content.

Is there a tool or a macro that helps in creating a zipfile of your sourcecode. Often when I post a project to codeproject, there's always a file(s) missing I didn't think of. It would be easy when you create such a zipfile from within Visual Studio.
|
|
|
|
|
...a simple DevStudio add-in!
There's an MFC class somewhere on CP which handles Zip/UnZip, so it wouldn't be too hard to do, methinks.
The only trick would be identify which files to add, and which to leave out (whouldn't be too difficult).
If you want to learn how to write add-ins, this sounds like a good project

I know the MFC Zip/Unzip because I developed an ATL-based version from it : SAWZip. Do you know how to program a DevStudio Add-in?
|
|
|
|
|
I started one last week, and it's easy. I got it in a night so I have an add-in that creates a text file of bookmarks, with comments, brings them up in a dialog, and I can select them and jump to the file location. Not much, but it *will* be cool when it stores bug history in an ADO database and links to our bug tracker at work.
The point is that it is easy. I considered doing it myself when I originally saw your comment. Just spend an evening in the MSDN and look at some samples. If you get stuck, I'd be happy to collaborate on a CP article that does it ( it sounds like we have the required bits between us ).

Beaten to it again!
Add-Ins are easy, though there are (as ever) a few funnies to contend with (toolbars, grrr.  )
Seriously, both sound like excellent ideas to me, and if there's any way I can assist, please feel free to ask. 
Hopefully I'll be publishing my own VC add-in (The Resource ID Organiser Add-In for Visual C++ 5.0/6.0) on CP very soon.
Then...SourceSafe add-ins look challenging....

I need to program a simple 3 octave piano keyboard using MFC.
I may paint bitmap with keys and handle clicks, then use PtInRegion.
But I would rather use buttons.
Is there any easy way to form MFC CButton with region shape (SetWindowRgn).
Well, you may have better idea.

This may help. You will need your button controls to overlap, though. That shouldn't be a problem, since they won't paint over each other.
