I have three CBitmapButton controls and I can't figure out what flags to specifiy in Create to allow all three buttons to hold their state independently of each other. Right now it appears they are grouped, when one is down the other two are up and so on. do OWNERDRAW buttons lose the ability to keep state? Do I create a GROUP button for buttons I want to be synchronized with each others up/down state? I'm not specifying WS_GROUP explicitly so I can't figure out why the buttons are acting like grouped buttons.
Anyone care to fill me in on how this is done???
I'm creating the controls at runtime in a CView so i'm NOT using the dialog editor.
TIA

I think that is actually the problem, WS_GROUP specifies the start of a group of controls. If you want each button to act seperately, then put each button in its own group.

Tried that too...still no successs I even tried !WS_GROUP in case WS_GROUP is implicit. Don't know if it had any internal effect, but it didn't work either.
I'm doing something that I shouldn't obviously...so I gotta backtrack and figure that out first. 
Thanx again!

INTRODUCTION
-------------------------------------------------------------------------
Hello,
First of all let me thank you in advance for reading my question.
And let me excuse for my english, I'm just a begginer with it.
I have never had time to learn the "best way of working" in VC++6 and now I'm concerned about the fact that I need to use some parts of my code in almost all the applications, some other parts have to be used sometimes, and so on...
I'm a Numerical Control Machine Program developer.
QUESTION
-------------------------------------------------------------------------
OK, I've developed some classes that I need (i.e: a dialog-box that is used as a control and that shows the coordinates of the machine).
I would like to know how should I use them in my new projects, wich is the best way?
1:
I know I can link them in DLL's and then create instances of those classes, but then I cannot get the parameters list in the code editor while I'm writing calls to it's methods.
2:
Should I add the classes in each project and recompile all of them again?
This allows me to get the parameters list while I'm editing.
3:
I've seen something as an object library in the VC++6, could it be used for that pourpose?
4:
Is there any other method?
As you have seen I don't know wich method use, could you give me an advice?

Probably the simplest method is using your utility classes in source code form. Some programmers have a personal utility directory where they put all that stuff, and feed the projects from there so that there are no duplicate files.

I've never relied on the editor's Intellisense stuff for writing my code so I'm not sure what makes it work and what makes it break. I personally recommend you don't rely on it either since it can be the cause of frustration. At any rate, assuming that you include the header files for these classes at the top of your project's CPP files, the editor should pick up the method signatures for the Intellisense. Have you tried this?

You can definitely do this, although it's not my favorite way. I prefer the DLL way (above). However, you can also opt for putting your common classes inside on directory and including them into your various projects straight from there (without copying them). This avoids having multiple copies of the common files across each of your projects. Still, it will mean that each project will carry around the same code which, IMHO, is best kept inside a separate DLL.

I don't know about this. I do remember once adding code for a splash screen via this thing, but I don't remember how it was done.

Mandy's advice is good, but a little expansive. In the first instance, get the OpenGL red book and check out nehe.gamedev.net. They are the best sources of info.

How can I add the current date (DD-MM-YY) in an edit box, when a user add a new record?

Your question is not clear,but why don't you use "Date Time Picker"?

I'm looking for CPUStress or a similar utility. (I thought it was available with the Free W2K ResKit downloads, but couldn't find it.)
TIA

Are you looking to (also) reduce the amount of free RAM available to the app being stress tested?

would be nice if it's in one package, but not really required.
I just have a home-grown driver that I suspect to fail under high CPU Load, however, it's hard to reproduce.

OK. I was just trying to plug my product MemWatcher, but I don't think it's applicable.

I needed one a few months back so I just wrote it.
Mine just allocated a bazillion chunks of memory. Then, each of its 30 or so threads randomly picked a memory chunk and read and wrote to it.
It worked the machine pretty well. We were able to determine the broken bits of hardware in our system.
I could probably email you the source if you want it.

Has anyone added multi-currency support to an existing C++ application. I'm looking for any class libraries or function libraries to aid me in adding multi-currency support to a legacy VC++ application that also uses the currency type in associated ATL COM modules. I've already identified Rogue Wave's "SourcePro Analysis: Currency Module", but I would like to check out other options. Professional software, shareware, or freeware solutions are acceptable. Also any suggestions or comments on the Variant currency type.

Does anybody know the equivalent of the function Chr from VB in C++. I've searched wide and near with no success.

Just cast it to a char:
BYTE i = 55;
char c = (char) i;
/moliate
|
|
|
|
|
//1. //Have it as a string
string cplusplus_Chr(char cAsciiCode)
{
char retChar[2];
retChar[0] = cAsciiCode;
return retChar;
}
//2. Have it as char
void main()
{
char cInput;
cInput = getchar(); // cin >> cInput;
printf("%c",cInput);// cout << cInput; (Display it!)
}

Hi !
I have an explorer-like app, where I'm trying to implement a drag'n drop feature : I want the user being able to select an item in the list of the right view, and drop it in a branch of the tree in the left view.
According to MSDN, I created an COleDropTarget in my left view class, and registered it. Now, I have to implement a source on my right view, but I don't really understands what the MSDN explains.
Anyone could help me ?
Thank you in advance !
Jerome
