Have you considered/tried a stored procedure?

You can use JOINs with the COUNT() clause. Simply put COUNT() around the columns that you are querying.

I tried doing that (in SQL server) and it doesn't work...

Ok, so just use COUNT(*), leaving the JOIN and WHERE clauses intact.

Hi All,
I know that the compile options \Gh gets you the _penter and _pexit, which can be used to get function level timings.
However, now the trick is how does one get to the level of saying: Line 121 took 13ms, Line 122 took 14ms, etc...?
Has anyone got any ideas or documentation to read?
thanks,
Rich

That's not very clear. What are you doing with Filename, post some code ('If I give' is quite vague). And what error did you get ?

Hi,
Thanks for the reply.
This is my coding.
CFile cf;<br />
CString filename;<br />
int xu_flag;<br />
CString s; <br />
if(i == 1)<br />
{ <br />
s.Format("%d", (xu_picno/2)+1);<br />
filename = "c:\\temp\\";<br />
filename+=s;<br />
filename+="F";<br />
filename+=".jpg";<br />
}<br />
else<br />
{<br />
s.Format("%d", (xu_picno/2)+1);<br />
filename = "c:\\temp\\"; <br />
filename+=s;<br />
filename+="R";<br />
filename+=".jpg";<br />
<br />
}<br />
xu_flag = cf.Open(filename, CFile::modeCreate | CFile::modeWrite);<br />
cf.Write(sp_temp, xu_len); <br />
cf.Close();
This coding is for storing each frame of video file in jpeg format.Using Xu_picno, i can able to retrive pictures.So everytime the pic no changes,the filename will also change.Like 1F,2F...
My problem is ,i have to store those picture in seperate folders.
So i need to create folder in runtime.how to do that.
help me please
cheers

You can't create folder with CFile.
Use the _mkdir[^] function for that purpose.

Why not use:
filename.Format("c:\\temp\\%dF.jpg", (xu_picno/2)+1);
ramyasangeet wrote: xu_flag = cf.Open(filename, CFile::modeCreate | CFile::modeWrite);
cf.Write(sp_temp, xu_len);
If the call to Open() fails, there's no need to call Write() or Close().

What do you mean ?? You simply need to call this function with the name of the folder you want to create. Did you read the doc from the MSDN (the link I sent you) ? It's pretty obvious how to use it. Also, don't forget to include <direct.h> (also stated in the doc).

I suggest that you read msdn
CreateDirectory("c:\\test",NULL);
whitesky
|
|
|
|
|
in www.msdn.com
CreateDirectory
This function creates a new directory
_mkdir
Create a new directory.

thanks for ur reply.
I used the create directory function.
CreateDirectory("c:\\test\\",NULL);
To create another folder named front in the test folder,i used the same method.
CreateDirectory("c:\\test\\front",NULL); ,the folder is not creating..any other way to create subdirectories??
Also i have to store jpeg files in the created subdirectory.
How to do that.
cheers

you can use each name instead test use your favorite name
like this
CopyFile("c:\\a.bmp","d:\\a.bmp",1);

Are you sure that the c:\test folder exists? If it doesn't, CreateDirectory() will fail.
Why are you not checking the return value from GetLastError()?

hai everybody
i want to create a notepad using a single document application.can you please help me how can i create that application.

Hi,
The best way is to use the MFC framework and choose the SDI application templete...most of the functionality is alreay implemented in the same.
or you can refer the sample source code provided in the MSDN for the notepad application.
all the best.
