问题 I have been struggling to get the MSBuild to successfully build my .dproj file for the last few days on a build machine. First, I needed the EnvOptions.proj file from the developer's machine, which got me clear of the missing system.pas file, but now I am getting a compile error for a missing .dcu C:\Program Files\CodeGear\RAD Studio\6.0\Bin\CodeGear.Delphi.Targets(123,3): error : myproject.dpr(17) Fatal: F1026 File not found: 'mymissing.dcu' Now the path to "mymissing.dcu" is included in the

问题 I have simple form TForm1 with 2 panels. First with Align := alLeft and second with Align := alClient and empty frame TFrame1 . When i add following procedures to the form, everything works without problems. procedure TForm1.FormCreate(Sender: TObject); var lFrame1, lFrame2 : TFrame1; begin lFrame1 := TFrame1.Create(nil); lFrame1.Parent := pnl1; lFrame1.Align := alClient; lFrame2 := TFrame1.Create(nil); lFrame2.Parent := pnl2; lFrame2.Align := alClient; end; procedure TForm1.FormResize(Sender

问题 I've got a TDbGrid in my project, and I'm trying to have an event go off every time I change the selected row. Any change in row already updates all the data-aware controls linked to the same DataSource, but there are other changes to be made too, that I need an event handler for. I thought OnColEnter would work. According to the helpfile, it fires when: The user navigates to the cell using the keyboard. For example, when the user uses the Tab key, or the Home key. The user clicks the mouse

问题 Using Windows Print Spooler API's, we can print out XPS files. The problem is that the print spooler ignores the default printer settings . (We've given up on trying to apply printer settings.

Other

问题 How do i change the color of a TDateTimePicker ? A Date and Time Picker can have a color: Normally this is done by setting the Color : procedure TForm1.FormCreate(Sender: TObject); begin DateTimePicker1.Color := clLime; end; But when using version 6 of the Date and Time Picker Control, the color no longer works: I tried using SetWindowTheme to disable the style of the TDateTimePicker : procedure TForm1.FormCreate(Sender: TObject); begin UxTheme.SetWindowTheme(DateTimePicker1.Handle, '', '');
