Hello ArkM, When GetLastError() returned 122, ERROR_INSUFFICIENT_BUFFER, I tried the only thing I could think of, make the return variable longer. I with change to your recommended errorno() on Monday. Thank you. We need to know what a dragon is before we study its anatomy. (Bryan Kelly, 2010)

Thank you, I will make some code changes. Since the value from GetLastError() was not zero, I think that implies that there is an error. Perhaps I had best check the previous code. We need to know what a dragon is before we study its anatomy. (Bryan Kelly, 2010)

...Windows 7, 64 bit, Visual Studio 2008, C++ string t_string; ... long long temp = strol( t_string.c_str(), NULL, 10 ) long error = GetLastError(); *return_value = (int) temp; After finding that atoi returns 0 on error, I shifted to strol because it sets the system error value. However, if...

That made a difference. Now my_bitmap and ppvBits both are no longer zeroes. I was thinking that was the size of the bit map I wanted. I do find it curious that the size of the structure must be in there. There are no pointers, no arrays, nothing I can see that would ever change the size of...

I finally found out about: CreateDIBSection API and found this: http://www.codeproject.com/KB/graphics/dibsection.aspx There is much more to do but now I have a clue. We need to know what a dragon is before we study its anatomy. (Bryan Kelly, 2010)

Visual Studio 2008, MFC, Windows XP I created a combo box with a drop down that displays the numbers 01 through 12. The range will never change. The name is IDC_STREAM_NUMBER. After creating an even handler the name IDS_STREAM_NUMBER doesn't like putting the -> or . (dot) notation after it...

Visual Studio 2008, C++, Windows XP or Windows 7. Good coder but still novice with Visual Studio Summary: What is the simplest method of putting bits on the screen, least overhead. My project receives video bits from a telemetry stream composing an image of about 100 by 100 pixels. The...

Now I see my error. I was not reading carefully and did not recognize that LPSYSTEMTIME is a pointer to SYSTEMTIME. I was thinking that LPSYSTEMTIME was just a variant (one of many types, not variant as in BASIC) of the system time structure. I could have written SYSTEMTIME right_now...

The OP contains: mp_start = &m_start; If that is not a valid initialization please advise. At work I shifted to the type SYSTEMTIME and it works as expected. A second check of the VS2008 help utility shows LPSYSTEMTIME and not SYSTEMTIME. I find that rather curious in that it differs from...

RE: C_AR2_Messages.h *m_messages; and RE: You have bad declaration and syntax error in the OP snippet, then you are writing about mysterious "can't see" problems. You are correct, until you mentioned it I just could not see that error (the one in my OP). That's a typo in creating the post...

On my home computer I found and ran: SYSTEMTIME start_time; ... GetSystemTime( &start_time ); Which works fine. I am pretty sure I obtained LPSYSTEMTIME from the help VS facility at work. Visual Studio 2008 are running on both computers. I wonder why the difference and why the LPSYSTEMTIME...

I don't see an edit function in this forum so I must add a reply. I have partially figured this out. The new class needs to reference some types declared in the original. That results in each one haveing a include for the other. When I edit C_AR2_Messages and remove the include for...

Cool. You set me straight on a couple of points and I have the maps working well. Thank you, We need to know what a dragon is before we study its anatomy. (Bryan Kelly, 2010)
