Note that thread function must be either global or a static class-method.
I wanted to say it cannot be a non-static class-method as you were using.

how to use "resource only dll"

16-Dec-05 1:49

when a function is a class member (except static ones), it receives an implicit parameter which is the this pointer. this implicit parameter changes the signature of what you see of your function in design mode...

for instance :

class A {
  public:
    void foo(int);
};

just considering the case of this function, its signature is in fact :

void A::foo(A*, int);

so, as AfxBeginThread() receives a function pointer, this parameter must implement a particuliar function signature, it must be exactly as you defined it. this is why your function must be global, or at least static (because static members don't know specific instances of a class - they are also known as class function)...

hope that helps...

Hi guys,

I've been out for a while and now I have to adapt a program for an interview to test my skills. It's all bmp's, so opening, rotating, changing colors etc...

I've been searching a bit, but of course MSDN isn't helping and I couldn't really find something on CP either.

Can anybody point out a good tutorial or something?
I do know how bmp's are built (a header and then the colors row by row)

I'm really confused with CBitmap and HBITMAP (and if I'm not mistaken you've got a Bitmap and BITMAP too?)

tnx!
(PS: my interview is on monday so I've got a lot of studying to do)

No hurries, no worries.

If the images were BMP format instead, you could use:

HINSTANCE hLibrary = Loadlibrary("MyResources.dll");
HANDLE hImage      = LoadImage(hLibrary, "MyImage" ...);

GIF images can still be loaded from the DLL, but with a bit more code:

HRSRC hResource  = FindResource(hLibrary, "MyImage", RT_RCDATA);
HRSRC hLoaded    = LoadResource(hLibrary, hResource);
char *lpResource = LockResource(hLoaded);
// now you can do something with the GIF bytes pointed to by lpResource

unplug the mouse from the first computer then plug them into the other computer. this way you can control the other system. Cool | :cool:

Now I can generate a clock at one pin of LPT port, by the way using Outport() and Sleep(t), but t min = 1ms, so that I only generate max freq = 500 Hz. I want to ganerate clock with higher freq (about 10 to 100 kHz). How to do that ?
Pls help me.

False, it's even worse than that: as windows is not a real time OS, your 1 ms are likely to vary up to 15 msec (depending on a lot of things). So, you can't rely on Sleep for precise timings like that.

For the solution to your problem, I don't even know if this is possible to do that in windows. Maybe consider to move to a real-time OS (like eCOs,...). I don't know if this is possible for you. Even going at the driver level, I don't konw if this will be possible...

Can anyone help me with jms call in c language!

Hi,Every one:
I just use jms lib to send message to jboss server.
And I useing C to do this work.
But I doubt there is memory leak when call jms api.
I have a test with create one instance of Message and set the message with new text context when sending the message.
After send 20000 messages,the memory requirement increase 2000K +.
I don't know where I am wrong.
So,please anyone can send me a sample with call JMS lib in C language.
(include create context,connection ,send message and destroy all instance)
Thank you very much!

Don't look at me in that way!
