I am useing VC++ to create a top score dialog box for my game. Even though I have the button set to Default Button, pressing Enter key does not work. I also used Spy++ to try and find a message that I could use to intercept an Enter key press, but no messages are sent to either the parent or dialog box when any key is pressed. Any suggestions? Thanks, Kars

"The button"? You mean an OK button on your highscore-dialog? Have you tried clicking it with your mouse? Does that give you the right results? If yes, set the focus to the button manually, using the TAB-key on your keyboard. Then press enter. Does it work then?

In other words : try things out, and if you post here, you might want to describe more precise what you''re doing.

I am trying to set the dialog box up so that if the enter key is pressed while you are in the dialog box, it is the same as ckicling the ok button.

This is what I have tried so far.

Tabing to the button and pressing enter, does not work.
Clicking the button, does work.
Pressing the space bar allways works, but not sure why.
I tried to set the focus programaticly under the WM_INITDIALOG message, does not work.
I also tried setting various properties on the button in the resource editor, didnt work for me.
I also spent about 2 hours last night tried to find some documentation in MSDN on this. So either it is not in MSDN or more likely I am not searching on the correct words.

Here is the code from my dialog box:

  
BOOL CALLBACK TopScoreDialogBox( HWND hwnd, UINT message,
								 WPARAM wParam, LPARAM lParam )
{
	HWND TempHwnd;
	char Score[25];
	char Level[25];
	int i;

	switch( message )
 	{
	case WM_INITDIALOG:

		for( i = 0; i < 10; i++ )
		{
			itoa( TopScores[i].Score, Score, 10 );
			itoa( TopScores[i].Level, Level, 10 );
			SetDlgItemText(hwnd, DlgIDs[i][NAME],
						   TopScores[i].Name);
			SetDlgItemText(hwnd, DlgIDs[i][SCORE],
						   Score );
			SetDlgItemText(hwnd, DlgIDs[i][LEVEL],
						   Level );
			if( TopPosition == i )
			{
				TempHwnd = GetDlgItem( hwnd, DlgIDs[i][NAME] ); 
				SendMessage( TempHwnd, EM_SETREADONLY, FALSE, 0 );
			}
		}

		return 1;
	
	case WM_COMMAND:
		switch( LOWORD(wParam) )
		{
		case IDOK:

			GetDlgItemText( hwnd, DlgIDs[TopPosition][NAME],
							TopScores[TopPosition].Name, 24 );
			
			EndDialog( hwnd, 0 );
			return 1;
		}
	}
	return 0;

}

I am out of ideas on what to do or look for on this. Any advice would be appreciated.

Are you sure you created the button correctly? Show us the part of your resource file where the button is created.

trap the VK_RETURN message

ELS1 is right. you should trap the return message by using something like
case WM_CHAR:
switch(wparam)
{
......
case VK_RETURN:
SendMessage(yourbuttonhwnd,.....);
.....
just send the mouse button press message(forgot the constant name) to the button.. that should clear things up

Here is the dialog box as it appears in the resource file.

I also tried traping the VK_ENTER witht the WM_CHAR and WM_KEYDOWN messages but thats not working either. Again Spy++ is not showing any messages for either the parent window or the dialog box when I press any key.

Any other suggestions?

from msdn on WM_INITDIALOG... "The control to receive the default keyboard focus is always the first control in the dialog box that is visible, not disabled, and that has the WS_TABSTOP style. When the dialog box procedure returns TRUE, the system checks the control to ensure that the procedure has not disabled it. If it has been disabled, the system sets the keyboard focus to the next control that is visible, not disabled, and has the WS_TABSTOP. "

so you have 2 options, in the resource editor change the tab index on the ok button to be #1 (i believe its in the menu Layout/TabOrder) and return 1 from WM_INITDIALOG OR you could return 0 and set the focus programmatically in WM_INITDIALOG.

Fixed the problem. I was creating the dialog box with CreateDialog, but when I changed to DialogBox it works fine. If any one wants to venture a guess as to why that fixed the problem, I''d like to hear it.

Thanks,
Kars
