you could use a string tokenizer[^], and then just count the occurences (that mean, is the example above, count the vector size)...

Ok, I've read that page. But little bit difficult to me, because vectors and stuff in C++ are new topics for me. Anyway thanks for the link again, I'll try it after doing some works with vectors.  
I appreciate your help all the time...

Another option would be to use strtok.

How can I change the color of GridLines that appears when I use the EXTENDED STYLE for List Control.
m_ListCtrl.SetExtendedStyle(LVS_EX_CHECKBOXES | LVS_EX_GRIDLINES);

I want to use ZwCreateFile() and ZwQueryInformationFile() in wdm.h or ntddk.h.
but if I incluce either of above,there would be hundreds of typedef redefining errors like PVOID64,and so on. The messages said the types had been defined in winnt.h.
But if I conclude winnt.h there would be more errors occur!
Someone would tell me how to resolve such errors?
Thanks.
GOOD LUCK

what about the preprocessor #ifdef, #ifndef or #pragma? Do they help?

i don't think they will. in fact, i hope files from microsoft SDKs like wdm.h or ntddk.h already have such inclusion securities...

You cannot include the ntddk.h in an application with the windows.h. so the only turn around is to copy the function definition from the ntddk.h and paste in one for your local file.

that's bad. where will he find the implementation of the function then ?

But thats the only way. You might be aware that that function are implemeted in the ntdll.dll. But Platform SDK or visual c++ dosent offer a ntdll.lib file so that he can staticaly link his application to ntdll.dll. So only chance is to load that dll dynamically and call those function.

Have you tried your luck with ntifs.h ?

You can't include those in normal user-mode programs. They are strictly for kernel-mode or native-mode programs.

Perhaps that is true.But I really what read some information from my USB device.My two task are these:
1.When I scan a USB device plugged,I want to get its driver letter like G,H,and so on.For example,i get a device instance like "USB\VID_0AC8&PID_301B\5&37FD04DB&0&2" using SetupDiGetInterfaceDeviceDetail,so I using that path to create a HANDLE(using ZwOpenFile),then I want to call ZwQueryInformationFile() to get some information,or call ObReferenceObjectByHandle().But these functions are decleared in wdm.h or ntddk.h.
2.The document of my USB device(or storage)says that,the special information should be retrieve by SCSI INQUIRY,I find it is IOCTL_SCSI_GET_INQUIRY_DATA command.But I do not know how to do.
I will be very appreciated if someone give me some advice.
Thanks.
GOOD LUCK

You can do this without using the functions from wdm and ntddk. After you get your device's name using the <code>SetupDi</code> functions, open a handle using <code>CreateFile</code>. Then use <code>DeviceIoControl</code> to send the IOCTL_SCSI_GET_INQUIRY_DATA to the device. Google on that IOCTL and you'll find some examples of calling it from user mode.

how to generate a random number within a range ( eg: between 5000 and 7500 ) ??
Thanks & Regards

Make it for 0 to 2500 and then add 5000 :P

Definitivelly, there is people that are blind and don't see the symbol of "joke" in the posts. I put a 5 to compensate the bad points.

Oh I don't care about bad votes of such people. Anyway, thank you very much I really appreciate you kindness.

On statistical grounds (don't ask me why  ) the best better approach is instead the one provided by the MSDN sample http://msdn2.microsoft.com/en-us/library/398ax69y(VS.80).aspx[^], i.e.
int u = (double)rand() / (RAND_MAX + 1) * (range_max - range_min)
+ range_min;

Hi All,
I have functions A & B.
A will be the starter. A will call B.
Again B will call A.
This call will go recursively until a condition is satisfied.
But after around 200 executions, if the condition is not getting satisfied, Stack overflow happens.
fn A{
......
call fn B
}
fb B{
......
call fn A
}
Is there any way to call function B after the complete execution of A is getting finished. So that the scope of A will be completed before calling Function B.
What if call PostMessage in this case?
Any help would be appreciated...
Thanks in advance.........

IMHO it is a bit too early, but anyway....

I think the question is: is the algo recursive?
If the answer is yes, then you can either try to increase stack size or transform the algo to do iteration instead of recursion.
If the answer is no, then you have to modify your buggy code.

You may be able to prevent this problem by passing less data with each call, passing references instead, keeping your data in a heap allocated structure etc. These changes may be simpler than changing the algorithm. If you post a few more details, function signatures, some idea of the data structures involved as solution may present itself.
Nothing is exactly what it seems but everything with seems can be unpicked.
