CString::Format()

[Oriented]

visual C++ how to add a formatted CString value to the original value, e.g: how to achieve these logical statements?! CString str; str += str.Format(" qer23 %d asdgsgd", var); :omg:

str.Format(...) doesn't return a string, it reassigns to str in-place. You'll need to use a second variable for the Format() call and append that to str. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- Pinky, are you pondering what I'm pondering?

You must use another variable for this purpose.

CString str, strTemp;
strTemp.Format(" qer23 %d asdgsgd", var);
str += strTemp;

This approach won't work. To quote from the MSDN documentation for CString::Format() The call will fail if the string object itself is offered as a parameter to Format. For example, the following code: CString str = "Some Data"; str.Format("%s%d", str, 123); // Attention: str is also used in the parameter list. will cause unpredictable results.

yeah sounds logical, coz its working on the same object, i assumed that a copy of the parameter would be made.

If you are using VS.NET 2002 or later, the CString class includes the member function AppendFormat, which does what you are asking. If you are using VC6, you will need to do something like this:

CString str,tmp;
str = ";kj;lak;sajlg";
tmp.Format(" qer23 %d asdgsgd", var);
str += tmp;
