From the help it looks like the StyleServices function can take a parameter that specifies the control you want the style info for. So, have you tried to pass a main menu instance as this parameter? Or look at the drawing code in vcl.menus.pas, that should show you how the vcl gets the colors to draw with.

Components dropped at design time load their properties from the dfm file after the constructor has executed. To set a property to a different value you need to override the Loaded method and do the deed there.

I assume Forms.Dialogs.pas is a unit not defining a form build in the form designer? In this case I would export functions from that unit that internally create and show(modal) one of the specific form classes, setting any needed setup values from parameters passed to said functions and returning any data entered/selected by the user as function result or in var or out parameters. This way other units need not require the specific form class units in their uses clause, only Forms.Dialogs. Note that the dialog forms would not be autocreated in this setup, the exported functions would all create, show, and then free a new instance of their dialog form.

The VCL has to work in the API environment that Windows provides. So aim your criticism at Microsoft ;).

You are wrong, the design makes eminent sense for a message/event driven environment like Windows. A modal form has its own internal message loop and that needs a way to figure out that it should exit the loop. Modalresult <> mrNone is that condition.

The IDE requires Win10 or 11, but applications build with it can run on older Windows versions, depending on which features they use. It may be necessary to modify the default manifest, though, if it specifies a newer Windows version as requirement (have not checked if it does).

Yes, my bad. I'm getting old ... 🙂

in a dynamic 2D array ( a type like TMyArray = array of array of integer) you can set the number of rows with a SetLength call on the array variable and, for each row, set the number of columns with a SetLength(arrayvar, rowindex) call. That should cover your requirements. To reduce memory fragmentation you should avoid multiple SetLength calls on the same array row or the array itself, though. Determine the number of rows/elements beforehand, if possible.

Well, it has to be something you do in your code then. I just created a new VCL app (D12.2), dropped a TRichedit on it, build and ran and it inserts an image (jpg in this case) dragged from Explorer to it just fine. If you now handle WM_DROPFILES or such try to disable that.

XE6 and D12 use different versions of the Windows richedit control as far as I remember, that may explain the change in behaviour you see.

Looks like the GetAdminSection function does not return an automation-compatible interface. Can you check what VarType the returned OleVariant has?

Try Result := not (VarIsClear(OleObject) or VarIsEmpty(OleObject) or VarIsNull(OleObject)) and (VarType(OleObject) = VT_DISPATCH);

If you open the wsdl in a browser you will see that it is very complex, importing a lot of xml schemas which partially import other schemas, using a host of namespaces. And the schemas seem to be not valid in some cases, e.g. by using namespace prefixes like tns: without defining them. The wsdls also refer to a script but fails to define a namespace for it, no idea if that is valid.

Look at this help entry for an overview of how to modify the way a TDBGrid is drawn. In your case set the DefaultDrawing property of the grid to false and attach a handler to the OnDrawColumnCell event. The handler can check the attached dataset's current row to see what row it has to draw. If it is the first just call the grid's DefaultDrawColumnCell method directly. If it is the second row change the grid.canvas.font to bold first and then call DefaultDrawColumnCell. That should do what you want.
