Writing A control in VC++ for VB...

[rjr9999]

Hey, I posted this in the Microsoft: C++ forum to no avail...I havn't seen activity there all day, I was hopeing someone here could help, or at least comment

-----------------------------------------------------------

Hi, I'm a VB programmer, and I need to write a Rich Text Box control in Visual C++ (For speed isues, text manipulation in basic is bad ). I'm not haveing any luck with it though, I used the MFC ActiveX control wizard and all I can get it to do is display an oval...I used add new dialog box, but I can't get the dialog box to display...What am I doing wrong? Can someone give me an example of how to make a Rich Text Box to display instead of that stupid oval? Any help is appriciated. Oh, one more tidbit, I'm also somewhat fluent in C...not C++, so I know how to do the actual text manipulation, I just don't know how to call the text object from the RTB...like in basic it would be RTB.text...how is this done in VC++?

In your ActiveX MFC Control you should add a property named "Text" like this (in VC++):

1. Open ClassWizzard (with ctrl+W)
2. On Automation Tab Select Add Property:
3. Select Get/Set Method
4. In the external Name box write "Text"
5. Ok

Now you will have to write the two Methods GetText and SetText. From VB You will see only a property named Text, not those two methods.

Take care when you write the visual part of the SetText. I think you will have to Write with TextOut or DrawText

Ah, one more thing, as far as I know an ActiveX's DC takes the Mapping Mode of the client program so make a call to SetMapMode before write something. (I am not sure on this issue).

Hope this helps you,
