Can anyone explain me somethings about the COMMTIMEOUTS struct of the SetCommTimeouts API function?
When I set the ReadIntervalTimeout member to MAXDWORD and the ReadTotalTimeoutMultiplier and ReadTotalTimeoutConstant to 0 the ReadFile operation doesn't wait. Is that right?
And what's with the Write... members? When I write 0 to this members, the timeouts will be ignored and the WriteFile function doesn't wait. Is that also right?

Yes, that's right.
Quoted from MSDN:
"A value of MAXDWORD, combined with zero values for both the ReadTotalTimeoutConstant and ReadTotalTimeoutMultiplier members, specifies that the read operation is to return immediately with the characters that have already been received, even if no characters have been received."
"A value of zero for both the WriteTotalTimeoutMultiplier and WriteTotalTimeoutConstant members indicates that total time-outs are not used for write operations."
Maybe you should read a little bit, eh?
Cheers,
Fredrik

I am doing sometimes a little bit of serial communications. You have to read a BIG bit and test, test, test ... til u drop

I have been looking for bar, line, and pie chart/graph in c++ that I can add to my project. I do not mind paying a reasonable fee, but everything I have seen is for .Net. I need c++ that can be used in my projects. Any leads?

Thank you for your efforts, unfortunately I have seen all of those with no luck. I am now searching the internet for commercial graphs. Thank you.

I have the following sample code in a DLL:
#define DllExport __declspec( dllexport )
#include <vector>
class DllExport Archive
{
protected:
std::vector<void*> m_vPointerStored;
};
and get the following warning:
d:\libs\saiggeneric\test.h(11) : warning C4251: 'm_vPointerStored' : class 'std::vector<void *,class std::allocator<void *> >' needs to have dll-interface to be used by clients of class 'Archive'
It only seems to be a problem with STL members.
My understanding is that using __declspec( dllexport ) for a class makes the class and everything in it exportable. I'm trying to build a straight C++ DLL, not an MFC Extension DLL. I don't know if this has anything to do with the problem. Help!!!!

Thanks, that's exactly what I needed to know. I had searched around the MS Web site, but didn't find this.

Hi All,
I would like to initialize a char array to hold a path retrieved from a registry key. If I used _MAXPATH constant from stdlib.h like this .... TCHAR MyPath[_MAXPATH], would this ensure that the array will be large enough? Even on 98, XP, NT?
Thanks
Paul

Never trust your inputs, especially when the source is the registry. Any user could go change your data to something longer than MAX_PATH, which would overrun your buffer, and we all know that only leads to Bad Things.
Call RegQueryValueEx() with NULL and 0 as the buffer and size respectively, and you'll get back the exact size of the value in bytes. Alloc a buffer of that size, and you'll always have a big-enough buffer. Check the type as well, make sure it's REG_SZ like you expect.

I would not stick to it. As someone says, never trust your inputs - that's the first reason, second reason is, that this will hardcode the _MAX_PATH to your buffers forever. And now it might be that these 260 chars is enough, but will it be enough next year?
