Windows timer resuloution is about 10 ms, so if you want a timer at 20 you can do ith with the windows timer. Less than this you have to go to specific HW, or, on later windows OSs, apparently you can change the timer, but it is apparently illadvised. So yes, your solution will incur a performance hit because of the kernel to user transition. I took over a sw and driver design once that wrote data byte by byte to a RAM pack. It took 30 seconds to fill the thing with data. I changed it to writing 2 k packets at a time. It too 250 ms to fill it with data. Thats the cost of switching form user to kernel to user every byte, as oposed to evert 2k bytes. Heavy eh? ============================== Nothing to say.

Hi, the allocation granularity size, if you look at the code, is system dependent: SYSTEM_INFO sinf; GetSystemInfo(&sinf); [... snipped ...] // Determine the number of bytes to be mapped in this view DWORD dwBytesInBlock = sinf.dwAllocationGranularity; I don't know the values for recent Windows OS's, I cited 64Kb just to say a size, you may just get them from the API (GetSystemInfo). As far as what would be the best value, I would say that you should map in multiples of such allocation size and other considerations (as available memory for the system and/or the single process) come into play. You may have to experiment a bit to find the best for your requirements. Cheers Federico

Intellisense should still work, look at this to see if it helps clear up the problem: http://www.codeproject.com/Tips/180150/Including-stdafx-h-in-a-non-default-location.aspx[^]

You can create a C++/CLI class library and include the .lib and .h there. Then create a managed class in C++ that wraps the functions. Finally, make a reference from the C# application to the C++/CLI project.

normally c-compilers cast from left to right (implicit). if yours don't - cast yourself (explicit): positionData.msgPosLat = (int)(lat/(BEARING_SCALING * 180.0)); // (int)(double/(double*double)) AND lat = ( (double)positionData.msgPosLat * (BEARING_SCALING * 180.0)); // (double*(double*double)) // hint: don't define twice (BEARING_SCALING) have a nice day.

Nope :) Use it as follows: #define ARRAY_SIZE(_Array) (sizeof(_Array) / sizeof(_Array[0])) // This is the answer char *OPTIONS1_ENUMS[] = {"OPT_1", "OPT_2", "OPT_3", "OPT_4"}; char *OPTIONS2_ENUMS[] = {"OPT_1", "OPT_4"}; char *OPTIONS3_ENUMS[] = {"OPT_1234"}; void GetOptions(short enumValue, char** szOptions, int Size) { printf("Array Size = %d\n", Size); } int main() { // In the Main program call GetOptions() for 3 different sized arrays GetOptions(1, OPTIONS1_ENUMS, ARRAY_SIZE(OPTIONS1_ENUMS)); GetOptions(2, OPTIONS2_ENUMS, ARRAY_SIZE(OPTIONS2_ENUMS)); GetOptions(3, OPTIONS3_ENUMS, ARRAY_SIZE(OPTIONS3_ENUMS)); } BTW you should not call your arrays OPTIONSx_ENUMS: - as capitalized names are conventionnally reserved for C macros, and - they are not enums but C arrays of const char*. cheers, AR When the wise (person) points at the moon the fool looks at the finger (Chinese proverb)

Sorry Luc, as you may have noticed I am getting more confused, but think getting there from your last post. One field in this array was height which ranged from 0 to 10,000, but the LSB was 0.5, and the sign not used; e.g. bit 15 was data. So if you had 0000 0000 0000 1000 which is 8 then that represented 4 meters. I got this working and then turned to see why the heading and lat/long were not! But with heading which did use the sign and had a range of -1 to +1 and a very small LSB. May next question is are they a formula to handle these types of conversions. Just for a Windows platforn with the VS environment. Still need to sort out the two unsigned short Lat and Long.

Andy202 wrote: a few pointers as to use MFC C++ with UNICODE Since MFC uses CString, I prefer to use CStrings for all my strings. If a CRT string function is needed (because there's no equivalent functionality in the CString class) then it's easiest to use generic-text Routine Mappings[^] instead of using the char specific CRT string functions. This keeps all the code buildable regardless of whether it's a Unicode or MBCS build. Andy202 wrote: casting my way out of any problems If you use the generic text stuff described above, you shouldn't (very rarely at least) need casts. If the compiler complains, it may be that you need to convert a string to the type expected. Just remember Cstrings are wchar_t-based on Unicode builds, otherwise they are char-based. If you need to force a CString to a specific type regardless of the build configuration, then use the specific CStringA or CStringW type. Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Hi David. The problem was this line:- m_cModeDisplay.SetForegroundWindow(); I don’t know why I put it in, but it’s the usual case when you loose something they are probably in the first place you looked, but you sometimes don't look properly! For the same reason I thought that the problem was setting some property of the dialog, but I needed to debug the program and try and locate the area and then the line that was the problem! I just needed someone to deflect me from my perceived view of the problem so that I could find the real problem. Many thanks. Andy.

Hi, on WinXP the layout tab of the console allows you to modify its buffer and window size, and to make these changes permanent for all future console windows with the same title. on Vista the option is gone, it just always does it that way. So for both: do it once manually, then keep the title constant. :) Luc Pattyn [Forum Guidelines] [My Articles] Voting for dummies? No thanks. X|

You're welcome. I had to reverse-engineer the Visual Studio project and solution file formats a while back in order to automate our product branching process. I still don't understand it completely, but I found an approach that works for what we need. Software Zen: delete this; Fold With Us![^]
