I think this can be possible to use your allocated space, As Mike was saying in another message, I am also not finding this much useful. As If you have some use of this in your mine, please let us know. some points I found are : ** it'll never release memory, whenever you need memory you are just allocating(if not available then new page). If it started using same memory then it would become long task. ** If one have to use any dynamic variable like CArray, CMap etc. as used in MFC.

for 24 to 16 no idea come to mind... For 24 to 8 bit.. ya..you are right I have to iterate and find out about color usage, that's already going in my mind, For 256 colors we can make 216 colors by combinations of(0,51,102,153,204, 255)and other 40 colors I have not found yet..how to find these.. But I don't think, it's a good idea. I m working in this direction..but mind is still trying to avoide this method. Regards, Sumit K sumit_kapoor1980@hotmail.com

Hi All, I want to do Intelligent bitmap depth conversion. Convert XXX to XXX (without color lose): 24 bits --> 16 bits (If few color used that can fit in 16 bits) 24 bits --> 8 bits (If few color used that can fit in 8 bits) 24 bits --> 4 bits (If few color used that can fit in 4 bits) 24 bits --> 1 bits (If few color used that can fit in 1 bit) Do u know, How I can find this bitmap has exact color(with no color lose) to fit in lower depth? For example : If I have a 24bits baitmap, but that is using only two colors. These two colors can be shown by 4 bits bitmap without any lose of color, then I should use 4 bits bitmap WHY 24 bits. Thanks:) Sumit K.:) ---Sumit Kapoor--- sumit_kapoor1980@hotmail.com

I don't know it is fully possible or not with another API.. DeviceIOControl(). This API is used for similar type of work, even file related. Check MSDN for more detail. I think it would be only help that I can do. Let me know if you get any direct method(by e-mail).

Hi Jahfer, I think you just need to reach to cluster, then following function would let you know how many sectors are there in one cluster & bye info of sector. BOOL GetDiskFreeSpace( LPCTSTR lpRootPathName, // pointer to root path LPDWORD lpSectorsPerCluster, // pointer to sectors per cluster LPDWORD lpBytesPerSector, // pointer to bytes per sector LPDWORD lpNumberOfFreeClusters, // pointer to number of free clusters LPDWORD lpTotalNumberOfClusters // pointer to total number of clusters ); Then you need to iterate for sectors.

Hi.. I'm using Global variable in VC++ MFC by declaring variable in .cpp file. then I've to use "extern" to acces that variable from other file..that's OK!..if I'm working normal..But when I use to access that Variable from thread..then It gives Error in Relase varsion(NOTE: not giving error in DEBUG version).. 1. Whenever I need to write new value I use CCriticalSection variable & Lock & unlock while operation of writing.. e.g: CCriticalSection a1; a1.Lock(); bStopRightDownThread=true; a1.Unlock(); 2. This value is Continue used by thread & checked by thread..if this value change then thread take action as per value... Problem : It is giving Illigal Operation error & close application in case of RELEASE version, but working fine in case of DEBUG version. WHAT DO YOU THINK REASON OF THIS? THanks..I'm waiting for your reply...:) ---Sumit Kapoor--- sumit_kapoor1980@hotmail.com
