The message is descriptive enough: you're trying to assign an integer to a pointer. Please post Y, R, G, B declarations for further help.

You are trying to convert from a pointer to integer to an integer. And the conversion is not possible.
The error message was quite clear enough, don't you think ?

change to,

What if people here don't know VB? Try to explain your problem, rather than putting up some alien code here.

for (ctr=0; ctr <=15; ctr++)
{
dout[ctr]=' ';
}
for (ctr=0; ctr <strlen(strData); ctr++)
{
dout[ctr] = strData[ctr+1];
}
Provided dout and strData are character arrays (but if they are really character arrays, you probably don't need the above code ).

Why are you encouraging that person? I'm afraid this will be come a habit and the OP will come here with VB code on a daily basis. You must answer all of that, as a punishment.

If he need to translate some VB code to C++ then what would be the right forum?

What if the VB thing consists 1000+ lines and contains so many GOTO and ON ERROR RESUME NEXT thingies? Okay. My opinion was that the OP could have stated the problem, because she wants to learn Visual C++. Posting some VB code and asking for its Visual C++ equivalent would not teach her anything. Agree?
Also, we don't have a VB to C++ forum. The idea looks dirty to me.

It also could be a scam too do a school task. Write your task in a pseudo programming language, like that VB thing you're talking about. And then ask us to provide a real program.

We can give some hints and help her (since you know savitri is a female name, I'm not able to guess it for sure) to go on C++ and more on the OOP way.

Maybe someone catches that wrong question and handle it to show the right way.

Translating VB to C++ is not dirty at all. You may think the opposite, but there are a few VB skilled developers around (and there are, as well ugly C++ coders...). IMHO attacking VB without strings is only the last childish trend.

I think regardless of the no. of lines of the VB program, if the OP really wants to learn C++, then she must state her problem precisely, just like how everyone else does here. Just my opinion.

I'll agree on that.

You got me wrong here. I was emphasizing on the fact that we must encourage people from learning the new language the proper way, instead of providing them some kind of a "translation service", which may make them get used to this service.

Then you ignore the post and move on. A comment to every post, contrary to popular opinion, is not necessary.
Rajesh R Subramanian wrote: My opinion was that the OP could have stated the problem, because she wants to learn Visual C++.
The problem was stated with code. That's good enough for, and easily understood by, most.

No, not at all. But then everyone has a right to their own viewpoint. Some folks are capable of learning a great deal by mapping what they know to a new language.

I missed that. Thanks for pointing out.

Did you can set Notify for static control?

Search CP for "static hyperlink" controls.
