ShowMessage works but application.messagebox dont

Question

ShowMessage('MAC  - (Client: '
        + DM.qTmp.FieldByName('CL_NR').AsString + ' , Place: ' + DM.qTmp.FieldByName('CL_DESC').AsString);

This code works fine, but how i can do that with

Application.MessageBox('MAC  - (Client: '
            + DM.qTmp.FieldByName('CL_NR').AsString + ' , Place: ' + DM.qTmp.FieldByName('CL_DESC').AsString' , 'Error', 16);

Got various errors [dcc32 Error] untPCName.pas(79): E2010 Incompatible types: 'PWideChar' and 'string' DELPHI version is 10.2.

Only gangstas use hard coded literal values rather than named constants for bit flags — David Heffernan, Jun 05 '19 at 08:13
What do you think that *E2010 Incompatible types: 'PWideChar' and 'string'* means? — David Heffernan, Jun 05 '19 at 08:22
That's **one** error. You mentioned "various". Are there more? — Uli Gerhardt, Jun 05 '19 at 08:23

To fix the "Incompatible types" errors you have to cast. Notice the PChar(...):

Application.MessageBox(PChar('Whatever'), 'Error', MB_ICONHAND);

I also replaced the magic number 16 with something sensible.
