It looks like you have gone down the Video For Windows route. You might want to consider stepping up to DirectShow instead. They are both old technologies, but VFW is just too old and annoying to deal with (we were using it on Windows 98). Whether you will be able to achieve 6 FPS really depends on several factors, primarily if your camera supports that frame rate at your desired resolution. You should be able to acquire the images as JPEGs or another bitmap format (RGB or YUV), but which formats are available depends completely on your camera. Take a look at this totally awesome CP article: Realtime Webcam Sudoku Solver[^] As I recall, it uses Video For Windows, so it should be easy for you to jump into the code and see how to access the image data. For a DirectShow sample, check out this CP article: Video Preview and Frames Capture to Memory with SampleGrabber in Buffered Mode.[^] And also browse through his other articles[^], it will not be a waste of your time. Here are a couple more DirectShow related CP articles: Simultaneous Previewing & Video Capture using DirectShow[^] DirectX Video Stream and frame capture[^] Soren Madsen "When you don't know what you're doing it's best to do it quickly" - Jase #DuckDynasty

Your code can retrieve the status. You may try to access the printer in some way so that the status is updated. But I have not done that and don't know how to do it.

try statically linking to the C-Runtime, ATL, and MFC... -Change C++/Code Generation/Runtime Library from /MD to /MT. -Change General/Use of ATL/ to "Static Link to ATL" -Change General/Use of MFC/ to "Use MFC in a static Library"

Best mac for visual C++? ...none really. Visual C++ is pretty much the name of the C++ compiler for Windows, so your question is a bit of a contradiction.

I explained you point by point where the problem is and how it occurred. Despite of it, you repeat your ideas about pointers. It is rather ridiculous, because I have the source code, generated asm file and result of disassembling of exe file (which can be compared with the asm file, generated by compiler). Finally, I can (and I did) run my exe file under debugger. You have no such options at all. Under such circumstances it is very strange idea to try to explain me not what actually happened, but what might happen!

Nothing, apparently. Veni, vidi, caecus | Everything summarizes to Assembly code

Put declarations inside extern "C" { } C & C++ uses different name mangling.

Thanks guys!

char* fname; int n_n = MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,fname,-1,NULL,0); LPWSTR yty; yty = (LPWSTR)malloc(n_n * sizeof(WCHAR)); MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,fname,sizeof(fname),yty,n_n);

Thanks everyone!

Well it works fine for me. Maybe you should explain why you think the result is not correct. Veni, vidi, abiit domum

Quote: Do you have any idea how to assign more than 1 LDR per buffer? That is not a problem, actually. Just perform the process sequentially on the LDRs e.g. Sample and convert LDR1, take the result from ADC1BUF0, store it in variable, say ldr1. Sample and convert LDR2, take the result from the same buffer ADC1BUF0, store it in the variable ldr2. ... Veni, vidi, vici.

here if the buffer_length=190 its generate out of memory exception. PBYTE buf = new BYTE[buffer_length]; it means it not working after certain limit. thanks.
