Simulate button control bn_clicked message event

1. The existing dialog box is as follows:

Click the button to bring up the Hello message box, as shown in:

The following code simulates the click RESPONSE event when you click the button:

Void ctestdlg: onbnclickedbtntest ()

{

// Todo: add your control notification handler code here

Wparam;

Wparam = bn_clicked;

Wparam <= 16; // shifts 16 bits to the left

Wparam | = idc_btn_say_hello; // bitwise OR

Lparam;

Lparam = (lparam): getdlgitem (this-> getsafehwnd (), idc_btn_say_hello );

: Postmessage (this-> getsafehwnd (), wm_command, wparam, lparam );

}

In this way, the Hello message box will pop up when you click the button.

 

II. The following two dialogs are available: test.exeand hisin.exe.

Click the button to bring up the Hello message box, as shown in:

 

Click the button in the hisin dialog box to simulate the click event in the test dialog box. The implementation code is as follows:

Void chisindlg: onbnclickedbtntest ()

{

// Todo: add your control notification handler code here

Hwnd hwnddlgtest =: findwindow (null, text ("test "));

Hwnd hwndbtnsayhello =: find1_wex (hwnddlgtest, null, null, text ("Say hello "));

Wparam;

Wparam = bn_clicked;

Wparam <= 16; // shifts 16 bits to the left

Wparam | =: getdlgctrlid (hwndbtnsayhello );

Lparam;

Lparam = (lparam) hwndbtnsayhello;

: Postmessage (hwnddlgtest, wm_command, wparam, lparam );

}

In this way, clicking the button in the hisin dialog box will bring up the Hello message box in the test dialog box.
