You can always do this even after a project has been created by using ClassWizard (Ctrl+W) to derive a class from CRecordset.

It depends to your knowledge of programming I suggest for start with classes for controls like(CBUTTON,CTREECTRL,....).

More info: Character Sets in C++[^] Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

You cannot typecast it - but you may have to convert it.    If you are in a Unicode build, both the BSTR and the CString are of the same character type, so you can just assign the BSTR to the CString (or use to construct one).    If not, you need to use a conversion function or macro: W2T(...), MultibyteToWideChar(...), etc.  Although CString may have a conversion constructor...?    Peace! -=- James Please rate this message - let me know if I helped or not! * * * If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

What answer are you looking for? :confused: You are assigning -1 (which is 255 for unsigned types) to result. :rolleyes: Until it is assigned some other value, it will remain as such.

rowdy_vc++ wrote: This is the problem. Indeed, since you have not shown any code that returns a value of 255.

If you only want to use a third party DLL you may simply add reference of DLL in your project and create an object of the class. If you want to inherit the existing DLL and want to extend functionality of existing class or control, by creating your own custom class library. Use following steps- 1) Start a project of type class library . 2) Add reference of existing DLL file. 3) Inherit the existing class, such as – public class Class1:ExistingDll.ExistingClass { public Class1() { // // TODO: Add constructor logic here // } } After this you may extend functionalities of existing class. I hope this helps. -Dave. Dave Traister, ComponentOne LLC. www.componentone.com

I tried this:: IFileIO.h #pragma once interface IFileIO { void setData(int xi); }; EDCService.h #pragma once #include "IFileIO.h" class EDCService:public IFileIO { public: EDCService(){}; int x; void setData(int xi) { x = xi; } }; Its works fine for me. I can create instance like this EDCService serviceObj; Try it and let me know how it works Manish Patel. B.E. - Information Technology.
