In system() function i am using "\". But this is not the problem.

All WIN32 API functions all accept both '/' and '\' (for NT at least), only some old command-line tools written for DOS might give you a problem there.

How is the function you're calling declared?
[modified]
I mean the function in the server.
What kind of argument are you supposed to pass, a VARIANT that contains a SafeArray?

Hi Roger,
Thanks for you reply ,
i have written a dll in C#.net and using RegAsm i created a .tlb file and i am using those functions in VC++6.0
C# function
void fun(byte[] input)
which is conveted to void fun(SAFEARRAY *input) in .tlb file .
now i dont know how to pass BYTE array to this fun function from VC++ 6.0

Ok, try the following:
- Create a SafeArray with a call to
::SafeArrayCreate() and set the VARTYPE parameter to VT_UI1. - Get the data buffer of the SafeArray with a call to
::SafeArrayAccessData() and copy whatever data you'd like into the buffer. - Release the bufer when you're done with it with a call to
::SafeArrayUnaccessData(). - Call the
fun() function.
Look the SafeArray functions up for information on how to call and use them.
Begin at SafeArrayCreate[^].

0x0f is not a NULL (that is 0x00).
Why did you expect 'i' (it looks like your device sends binary data)?

Why are you opening the serial port twice ? You can read and write from the same CSerial instance. BTW, from where is this CSerial class coming from ?

You could try something like this, don't know if this actually works or not, didn't try it, but it can be a starting point for you, good luck:
CDC ScreenDC;
ScreenDC.Attach(::GetDC(NULL));
CBitmap Capture;
CSize Dimensions(GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN));
Capture.CreateCompatibleBitmap(&ScreenDC, Dimensions.cx, Dimensions.cy);
CDC MemDC;
MemDC.CreateCompatibleDC(&ScreenDC);
CBitmap *OldBitmap = MemDC.SelectObject(&Capture);
MemDC.BitBlt(0, 0, Dimensions.cx, Dimensions.cy, &ScreenDC, 0, 0, SRCCOPY);
MemDC.SelectObject(OldBitmap);
MemDC.DeleteDC();
::ReleaseDC(NULL, ScreenDC.Detach());

Actually you know the logic. Maybe you don't know the realtive API.
What are your doubts about? Are you able to open and read the file?
Are you able to open and write to the serial port?

Are you intending to implement a key board hook...something similar to (Window's Key+d) that minimizes all the open windows and leads you to the desktop window

I want when I click next button ,next window should'nt appear until all the processing against next button is completed.I used Sleep(1000).It is doing but Interface color get black as I press next button.What should I do?

You can use polling technique to determine if a task is complete, or use some event notification to let you know about the task completion.
Alternatively, you can use a boolean variable and set it to true once the task is completed and keep on monitoring the variable until its set to TRUE.
Putting Sleep() in code is not a good idea. there are other techniques too.
