you need to class derived from CButton and use WM_DRAWITEM
if you want to change CButton
and in the Codeproject you found your answer
|
|
|
|
|
If you want to change background color you can override OnEraseBackGround Func.
else you override OnDrawItem to draw on your button.
You can capture message CTLCOLOR_BTN to handle such events at runtime.

Hold on!, i've been trying to capture these messages in the PreTranslateMessage, but i dont know what mistake i'm making. its not getting trapped. can you help me out?
<code>
BOOL CTESTMFC2Dlg::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message==WM_QUERYENDSESSION)
{
if(pMsg->lParam==0x80000000)
{
}
}
if(pMsg->message==WM_ENDSESSION)
{
}
return CDialog::PreTranslateMessage(pMsg);
}
</code>
Actually the 0x80000000 is to check if its a LogOff. the owner of this thread may also like to see your reply.

BOOL CMainFrame::OnQueryEndSession()
{
if (!CFrameWnd::OnQueryEndSession())
return FALSE;
AfxMessageBox("I caught System ShutDown");
return TRUE;
}
also c WM_ENDSESSION

|
|
|

If its a dialog based application?

afx_msg void CShutWindowDlg::OnEndSession( BOOL bEnding )
{
AfxMessageBox("Shut Down Message Caught");
}

|

Did you chage your post?? what's that afx_msg void?? it only returns a BOOL right?
Btw, still its not working.
I tried both ::OnEndSession(BOOL b) and ::OnQueryEndSession()
BOOL CTESTMFC2Dlg::OnEndSession(BOOL bEnding)
{
//Not entering here 
}
BOOL CTESTMFC2Dlg::OnQueryEndSession()
{
// Not entering here
}
What'd have gone wrong?

afx_msg void CShutWindowDlg::OnEndSession( BOOL bEnding )
{
AfxMessageBox("System ShutDown Message Caught");
}
Handel WM_ENDSESSION Message

Handle it again?? then what's the need for ::OnEndSession ??

Don't try adding those functions. Instead, go to your dialog view (where you can manipulate the button/textbox fields) click on the dialog somewhere. From there, go to the Properties tab. This is the place where you would normally set the button/textbox name, readonly, etc. Instead, click on the button next to the little Lightning bolt that is labeled "Messages." From there, scroll down until you see "WM_QUERYENDSESSION", click on that, and add OnQueryEndSession. From there your function will be added and implimented, and you can change what you're testing for inside of that.

Dear C++ gurus...
I would like to know how to declare a global function in VC++. I would want to call that function from any class just by calling the function. A similar comparision would be like declaring a global function in a module and calling it from anywhere, incase of VB.
Urgent help needed.
Thanks.

Declare it in stdafx.h and define it in stdafx.cpp.

But won't doing that affect other projects using "stdafx"? By Global, I meant global to my particular project so that calling that function from within my project would not need an instantiation of a class. Just call the function using its name alone. Can it be done ? What would happen if I used a static Function?
Thanks for replying.

the stdAfx.h is shared within a only project.
moreover, making a global function is a pretty bad habit in OOP. why would you need such a thing ?
can't you do a public static member function of a classe of your project which has a more common use ?
