DM_SETDEFID
An application sends a DM_SETDEFID message to change the identifier of the
default push button for a dialog box.
DM_SETDEFID
wParam = idControl; // identifier of new default push button
Parameters
idControl
Value of wParam. Specifies the identifier of a push button control that will become the
default.
Remarks
This message is processed by the DefDlgProc function. To set the default push button, the function can send WM_GETDLGCODE and BM_SETSTYLE messages to the given control and the current default push button.
Using the DM_SETDEFID message can result in more than one button appearing to
have the default push button state. When Windows brings up a dialog, it draws
the first push button in the dialog template with the default state border.
Sending a DM_SETDEFID message to change the default button will not always remove
the default state border from the first push button. In these cases, the
application should send a BM_SETSTYLE message to change the first push button border
style.
Return Values
The return value is always TRUE.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
