Hi

Where can I find an example on how to use the LMDTaskDialog ?

Thank you

Hi


bExit :=LMDTaskDialog1.Execute  ;

if bExit then ShowMessage('OK') else ShowMessage('no');

Why is bExit True for both OK & No ?

Demo: Check then two available TaskDialog demos

Second question: The return value tells you only that dialog was shown correctly. TaskDialog can have many different possible return values. Check the result properties instead:

    property ResultButtonId: Integer;

    property ResultRadioButtonId: integer;

    property ResultVerificationState: Boolean;

Hi Rafael

Have just checked but there is no such TaskDialog Demos in the LMD SE :-(

Can you assist ?

Thank you.

Get a trial and extract demos from there. SE does not include demos.

Hi Rafael

I tried

if LMDTaskDialog1.execute then
        ShowMessage(IntToStr(LMDTaskDialog1.ResultRadioButtonId)) ;

The LMDTaskDialog1 has 2 buttons, Ok & Cancel. The return value is 0 for both buttons.

I need to know which button is clicked to process the results of the btn click

Thank you

TaskDialog Demo - cannot compile
[Error] d_LMDTaskDlg.pas(157): Types of actual and formal var parameters must be identical

Please re-read your code snippet:

if LMDTaskDialog1.execute then
        ShowMessage(IntToStr(LMDTaskDialog1.ResultRadioButtonId)) ;

You want result of command buttons, not radio buttons. Use ResultButtonId instead. Return values are Modalresult values like mrOK for common buttons or userdefined values you have set in Buttons collection.

Regarding demo problem:

Most probably version mix up.

Hi Rafael

if LMDTaskDialog1.execute then
        ShowMessage(IntToStr(LMDTaskDialog1.ResultButtonId))

works :-) Yes returns 1 and No returns 7

Thanx

You should not use 1 or 7. Use the corresponding Modalresult identifiers (mrYes, mrNo, mrCancel, mrOk etc.).
