Property and Component Editor Info

[Leroy1981]

I am tinkering with property editors and comonent editors
for my custom components and I plan to use complex dialogs
for editing certain properties and components as whole. I already know how to override Edit() but I seem to be having difficulty getting the dialog box to work right.
Right now I have managed to get a form or frame to appear upon clicking the edit button but sometimes when I go to compile the test package that contains the editor/editee c++ builder crashes.

void __fastcall TXEditor::Edit()
{
// TForm2 only contains 1 TStaticText child
// I used NULL so dialog would be independent of
// main form
TForm2* Diag1=new TForm2(NULL);
}

It Says "Address Blah-Blah-Blah cannot be read". If you need the address let me know.

Thanks

I believe the problem is that TForm is expecting an address, usually this and it can't handle a NULL address. I've read several articles on creating custom dialog boxes but since I've never had to do it, I didn't pay much attention.

Most of the articles were in C++ Builder Developer's Journal. One article is available for the public (

http://bcbjournal.com/articles/vol3/9912/Extending_the_common_dialogs.htm).

The rest are for subscribers only. Great mag, FYI.

When I try using this instead of NULL for a form it cannot find match for constructor TPropertyDialog(TXEditor *const)

And I can't seem to get frames working either. That article talked about adding to existing windows dialogs but I need to be able to start from scratch.

Any Ideas?
