My suggestions are for VC++6, I don't know if that's what you will be using, but I have a few books and thses are my favorites Smile | :)

I am found Practical Visual C++ By Jon Bates & Tim Tompkins to very good starter / tutorial book & Programming Windows with MFC By Jeff Prosise is very good for MFC.

There are also lots & lots of great articles here on CP suitable for the beginner.

Happy Coding Smile | :)

CString to Numeric Value

Hi All

does any one know what would be the best way to convert a CString containing only
characters to a numeric value.

for example

CString str = "AFG"

output to be say

int 653790;

and each time you convert the str, you get the same result

Thanks

Si Smile | :)

Do you want a hash value of the string, or simply want each character in the CString to be converted to its ASCII value?

A simple function would do for that!

CString GetASCIICodedString(CString& srcString)
{
    CString srcResult, srcBuffer;

    for(int nIndex = 0; nIndex < srcString.GetLength(); nIndex++)
    {
        srcBuffer.Empty();
        srcBuffer.Format("%d", srcString.GetAt(nIndex));
        srcResult += srcBuffer;
    }

    return srcResult;
}

This should work... I've not compiled it, just some rough code, so please test it properly.

srcBuffer.Empty(); seems extraneous.

What about converting each character of the string to it's ASCII code (__toascii) assemble the results to a number ? I hope you understand what I mean, my english is not the best.

I have an application that is executing another and after that is closing itself. How can i detect in the second (child) application that the first (parent) is closed.

Re: Parent process

Neville Franks23-Sep-04 23:26

I don't understand. You've said the parent closes after the child closes, which means the parent is always running as far as the child is concerned.

No, after the child is executed and start running the parent is closed. But the child must to know when exactly the parent is closed. This is need because i must to change the .exe file. So i thought that i can try to open the .exe file and if this fails it is still running. But this is very unsecure. So i want either to check if the parent process is running or check somehow is the parent's hInstance valid.
