SendDlgItemMessage
The SendDlgItemMessage function sends a message to the specified control in a dialog box.
LONG SendDlgItemMessage(
HWND hDlg,
| // handle of dialog box
| int nIDDlgItem,
| // identifier of control
| UINT Msg,
| // message to send
| WPARAM wParam,
| // first message parameter
| LPARAM lParam
| // second message parameter
| );
|
|

nIDDlgItem
Specifies the identifier of the control that receives the message.
Msg
Specifies the message to be sent.
wParam
Specifies additional message-specific information.
lParam

Return Values
The return value specifies the result of the message processing and depends on

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

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 » |
