Well, if you can find those two values in the Performance Monitor, the solution is rather simple.

In the AppWizard and CodeWizard directories of Microsoft Visual Studio there are some code template files. These templates contain string substitutions such as [!output CLASS_NAME]. Does anyone know where I can find a list of these 'variables' and what they are substituted with? Also does anyone know if it is possible to add ones own 'variables'.

Hi all,
I have the following string: "MA01234 TEST" and I want to replace the number part of the string with a value of (just an example) "43210 ". So how can I replace the value within the string? What function can I make use of?
Example:
MA01234 TEST
TO
MA43210 TEST
Can anyone please assist me.
Many Thanks in advance
Regards,

Well, if your string fields have fixed format, then it is pretty easy (just replacing characters, I think you can figure how).
On the other hand, with variable field format you have to parse the strings to extract the numeric field (maybe the other ones) and replace it.
A powerful tool to do such string operations is a regular expression parser, like
Boost.Regex

The numbers that I provided was only an example it could have been alphabetic as well.

It is fixed and I'm not looking for the complete answer, but just want to know which function I can make use of to replace a part of the string from a starting location to a end location.
Thanks for the reply

Oh, if it is fixed you don't need functions at all (assuming ASCII strings):
int i;
char record[]="MA01234 TEST";
char new_field[]="43210 ";
for (i=0; i<6; i++)
{
record[2+i]=new_field[i];
}
of course hard-coded numbers are ugly, but I think the concept is clear.

There are I think 2 approaches to this. You can either use a regular expression engine (something I know next to nothing about but there are CP articles if you search) or you can code it yourself. A loop from 0 to the length of the string would be your basic algorithm, pick out the numbers either one digit at a time or as a group and replace them either in place or by generating a new modified string by partially copying the old one. The C Runtime has lots of useful functions like _isdigit and strcat which could help you and stl strings have useful things like functions to reverse strings as well. It important to decide if you're only working in ASCII here or only in UNICODE or if you want it to work for both.
This function seems very specific as well so you might want to break it down into more usefully generic things like bool find_digit_sequence_in_string( TCHAR* aString, int& iBegin, int& iEnd )
Nothing is exactly what it seems but everything with seems can be unpicked.

Thanks for the reply and the information provided. I will be working with ASCII and the numbers that I provided in my example was just that ... an example it could have been letter as well. Basically I'm looking for a function that will allow me to copy from a starting position to a end position within a string. Does something like this exist? I can think of a way to do it with string copy but it feels like a very long way to perform something like this.
Thanks in advance

stl strings have a substr function you can use for this
<br />
basic_string substr(<br />
size_type _Off = 0,<br />
size_type _Count = npos<br />
) const;<br />

std::string content can be changed using indices (operator []). Or you can use the replace member function. Either useing iterators or index and count.
Or you assemble a new string (e.g. using a std::stringstream) from parts of the old an new string.
The possibilities are endless!
For the case you presented, I would simply use the
string[i] = 'n' way.

for instance (inside OnDraw method of your View class):
...
CBitmap *pOldBmp, bmp;
bmp.LoadBitmap(IDB_MY_BITMAP);
CRect rc;
GetClientRect(&rc);
CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
pOldBmp = dcMem.SelectObject(&bmp);
pDC->BitBlt(0,0,rc.right,rc.bottom, &dcMem,0,0,SRCCOPY);
dcMem.SelectObject(&pOldBmp);
...

Or

Object serialization is a rather big topic. You can either exploit MFC serialization support http://msdn2.microsoft.com/en-us/library/6bz744w8(VS.80).aspx[^]
or develop your own mechanism (this can be simple provided your structures have fixed sizes).

Oh, you can do it. You have structs, after all.

There's an awesome book called 'Mastering Algorithms with C' published by O'Reilly. It's where I learned all this sort of stuff, highly recommended.

I'm developing a C++ program that should check whether SQL 2k5, Exchange 2k7, Oracle 10g are installed on the system. Based on whether one of it is installed the program shall invoke a different C++ function. The check shall be made by probing for certain registry keys/values by the C++ main program.
I would like to know which keys/values are set by the installation of
SQL 2k5
Exchange 2k7
Oracle 10g.
Also are there registy keys/values probing is foolproof enough to guarantee the successfull calling of the appropriate function?
On a sidenote are there any registry keys/values that are common and same for all the above three databases irrespective of different flavours. The idea is that the same registry check works for all the different version of a database.
