Hiding labels

[Kobbler]

Hi,
I have a simple question. I am making a custom dialog. I want to disable a label on the screen and then enable it later depending on the value of a variable. Could someone please show me how to do this. I thought I had it but for some reason it won't work.

The label will be disabled (made invisible) upon entering the dialog. It will then be enabled if the variable SHOWDIALOG is set to true.

Thanks in advance,
Kevin

Hello,

Try this...

prototype My_ControlVisible(BYVAL number, BYVAL number, BYVAL BOOL);

function My_ControlVisible(hDlg, nControlID, bState)
    number hCtrl;
begin
    hCtrl = GetDlgItem(hDlg, nControlID);
    if bState then
        ShowWindow(hCtrl, SW_SHOW);
    else
        ShowWindow(hCtrl, SW_HIDE);
    endif;
end;

Explanation:

The hDlg is the handle of the custom dialog. The nCotrolID should be the ID number of the label you want to be visible or invisible. Of coarse, the bState is a TRUE/FALSE value that will decide to hide it or not.

I think the ISMP control classes support a setVisible method with which you can hide or show controls; searching these forums for "setVisible" will turn up some examples.

It worked. Thank you.
