I am currently using rtx for some application and i obtained this warning after i editted some of the settings. I think the /DRIVER setting is required by rtx, but i dont see where the /EDITANDCONTINUE come from.
Does anyone know how to solve this warning ?

LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /DRIVER specification

I am currently using VC 6 and apparently /INCREMENTAL:NO is required for this application...

What are these WndProc WMs?

I came across the following window message codes sent to WndProc of the main form of a C# application. These messages are generated when the form starts up. There are no published WM_ constants for these. Does anyone have an idea what they represent?

UNKNOWN: 297 (H129)
UNKNOWN: 295 (H127)

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)
            {
                /*code here*/

            }

       }

   if(pMsg->message==WM_ENDSESSION)
     {
           /*code here*/     

      }

  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. Wink | ;)

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 Frown | :(

}

BOOL CTESTMFC2Dlg::OnQueryEndSession()
{
// Not entering here Frown | :(

}
What'd have gone wrong? Confused | :confused:

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.
