I am sure a simple solution exists for this problem.

But for data enter and validation via an Edit Box, using the EN_KILLFOCUS event.

The problem is, unless I set the Multiline properity, when Enter is pressed the dialog will close.

Are they a way to have Enter work the same way as the Tab key to signal the end of data entry?

Currently have to Tab out of this control to do the processing.

Many thanks.

If you set the Want Return properity, then still have to use the Tab key to move off that control.

If you just set the Want Return properity then dilog closes when Enter pressed.

Was just hoping to use Enter like the Tab key.

Any suggestions.

don't know how you're gonna do this Smile | :)

Your problem is that the OK button is set to default button and when you press Enter button, automatically OnOk() is called.So override the OnOk handler
void CYourDlg::OnOk()
{
//OnOk();
}
if you only delete the OK button without doing what i wrote above it won't solve the problem.
But if you have already deleted the OK button , then one way to avoid this problem is to add an invisible button and set is as default.

Thanks for your Post, but do not understand what you mean adding an invisable button and set as default.

Yes I have deleted the OK button on the dialog as it's a modeless dialog.

More help please.

simply add a button then in the properties window set the Visible checkbox to false and in the same window Mark the Default Button check box.

Ohh, you stilln't got the answer!.
Ok Handle OnOK() virtual function in your CDialog derived class and Comment Out any CDialog::OnOk() line.

i.e.

void YOURDIALOGCLASS::OnOk()
 {
  //Comment the Line
  // CDialog::OnOK()
 }

Now you dialog will not close on pressing ENTER key!

No Problem, add a Button in your Dialog Box and Set it ID to IDOK

OK almost there!?!

Now have the Multiline and Want Return set to False, dialog stays open when Enter hit.

Now just need the action of the Enter key to Tab onto the next control (i.e. Enter acting like the Tab key to end data entry)

Do you know how to do that please.

Thanks.

Capture ENTER KEY PRESS using WM_KEYDOWN Message and Then using keybd_event Simulate Tab Key press

I have added the OnKeyDown handler, but never enter it when I press a key.

I did add the Left Mouse button down, as a check and that too was never reached.

See part of the MESSAGE MAP

	ON_WM_KEYDOWN()<br />
	ON_WM_LBUTTONDOWN()<br />
END_MESSAGE_MAP()

Have I missed something out?

Also a bit unsure how to use keybd_event.

Pressing 'Enter' would cause Dialog box's OnOk() to be called.
One possible work around would be to override the OnOk function in your dialog class and do not call the base class method.

I'm certain that's not the actual message - what's the eror number ? Is IDB_NAME a bitmap resource ? Which line is causing the error ?

What's this ?? The error comes from there probably. For the definition of your class constructor, you have two different names for the class scope (CProjectLDlg) and for the constructor itself (CSkinDlg). I suppose it is not intended, so correct that and use the same name for both.

m_hWndRgn=DIBToRgn(m_hBmp,0x00ff00,FALSE);<br />
}<br />

this function is not a constructor. It's just a member function. The initializer list (see the bold code) is only legal in constructors.

Change CProjectLDlg::CSkinDlg to CProjectLDlg::CProjectLDlg. That should do the trick.
