What is the difference in terms of code generation with these two switches? I understand one if for DLL code and one for Multithread code, but it seems that this means I need to generate four static library versions with each library (six if I include single threaded), since I need a release and debug version.
Are people really generating six versions of each static library or am I just missing something important?

When you specify /MD the compiler will link MSVCRT.LIB(MSVCRT.dll/MSVCR71.dll must be available at runtime) to your object code. If you use /MT the compiler will link the static version of C runtime (LIBCMT.lib) to your application. There is no need for you to generate four static library versions.
You can choose either of these two. Multi-threaded runtime DLL Version(/MD) - Or Multi-threaded runtime LIB version(/MT).

I'm making a program that reads data from a device. The data is then used to make a graph in real time. The problem I'm having right now is that when I open any window on top of the graph it erases everything. How do I solve this problem? Any suggestions? Thanks

You need to save your data somewhere and paint everything in response to the WM_PAINT message only.
Whenever a part of your window needs to be repainted, you will receive a WM_PAINT message and you need to do the drawing there, and only there !

I was thinking, if it was possible to know when the window went out of focus, I could copy that section of the screen into the clipboard, and then repaste it when the WM_PAINT was called.. wouldn't that be easier, if its possible that is

nevermind, ur suggestion worked out perfectly, and it wasn't nearly as difficult as i thought it would be. Thanks!

ok I'm having another problem tho, It seems sometimes it jus stops painting. I don't know why this is happening, but by minimizing and restoring the program it starts to work again. Anyone know why this might happen?

One message to reply to all your questions 
First, your suggestion of using the clipboard when the window loose focus is not really good (it is even very scary): imagine that all applications will do that. Do you imagine what a mess it would be ? And the poor user which desperately tries to copy/paste something 
In fact, once you understand the philosophy, everything makes perfect sense. I suggest that you google to find some tutorials about win32 programming (you'll probably find some usefull articles on this website). If you plan to program in win32, it is highly recommanded.
Now, for your last question: in fact the WM_PAINT message is not sent continuously: it is sent only when your window needs to be repainted (so when you minimize it, when something comes in front of it, ...). But, if you need to refresh it (for example because new data needs to be displayed), you need to invalidate it, which will cause a WM_PAINT message to be sent. For that, you can call InvalidateRect[^]
While searching for the link to this function, I came upon this link[^] which is probably what you need to get started.
Enjoy

Hello,
I've tried the follwing code. everything works fine except conversion from _variant_t to char*.
Any idea of how to do it?
Many thanks for your advice.
int yy = 4;
int zz = 1024;
float ff = 13589.025;
char* chh = "MyString";
_variant_t** test = new _variant_t*[4];
for(int i= 0; i

I wanted to try Visual Studio Express as a debugging medium.
I brought over a project and tried to compile it.
It complained that it couldn't find afxwin.h which is all the MFC core stuff. I looked around and couldn't find it either on that computer.
My question is: can I add something to make the express edition support MFC?
Thanks,
Ilan

I am using "CreateFile" function for accessing CD-ROM drive in the service program but it is resulting in error. I checked error through GetLastError() and found error code = 5 (Access Denied).
But calling "CreateFile" function from other program (non-service program) is working fine for accessing CD-ROM drive.
Any idea/help would be highly appreciated.
Thanks

check the account type of the service, for instance, a LocalSystem one should have access to the CD-ROM device.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Yes, I have checked the service access and it is LocalSystem type service.
So what may be wrong with the service if it is already LocalSystem type? Probabily there is need to set security attributes of the service component through DCOMCNFG tool.
Thanks.

Hi
I am writing a program in Windows CE for a Palm PC.When I send a string that contains Turkish Letters which is not included in ANSI characters.And this characters are seen diferent in the Palm PC from what I sent.So I want to check these letters when it comes to Palm PC and I want to change the unicodes of these letters to make them seen the same that I sent.So my question is that How can I get the unicode value of a letter in a string.For example;
CString string = "letterX"; //Suppose that X is a Turkish letter
//The Unicode value of X is 351
int number1 = string.GetAt(6); //That doesn't work.It gives negative value.
unsigned short int number2 = string.GetAt(6); //That doesn't work.It gives
// 65534 which is not true.
How can I get the real unicode value of X?
Thanks

1. Do you have UNICODE and _UNICODE defined? If not, then your CString contains 'char', not 'wchar_t' characters.
2. What does 'send a string' mean? Over a network?
3. The negative number sounds like sign extension at work. Since UNICODE characters are 16 bit, you can mask off bits above that
int number1 = string.GetAt(6);
number1 &= 0xFFFF;
Does that help at all?
I'm confused as to why 351 would be reported as 65534, which corresponds to -2. Is this the negative number you got in the first place?

1.I am using embedded visual c++ and in that program Unicode was defined as default.
2.I am writing the program for a palm PC which will communicate for example with a computer.
3. int number1 = string.GetAt(6);
number1 &= 0xFFFF;
that lines gave again 65534.I don't know why it is giving this value.

I found the answer.
I am putting here because maybe there may be someone who wonders the answer.
UCHAR character = string.GetAt(6);
