I suffer from a rare c++ coding discapability, so plz bare with me..
I'd like to be able to add two texts together, to make a composed resulting text. What solutions are there to this problem?

I tried the strcat(), but i had endless problems, and i wasnt able to use it in the end.
I also tried using the "string stringName" thing, i managed to print it as if it was a (char*), but i wasnt able to add them together either.

You have three choices :

A) MFC & CString** :
CString temp;

temp=CString("\\")+CString("file.bmp");

B) strcpy & strcat
strcpy(temp,"\\"); <- Note double backslash
strcat(temp,"file.bmp");

In VS 2005*, they recommend you use the new security enhanced versions :
strcpy_s(temp,sizeof(temp),"\\");
strcat_s(temp,sizeof(temp),"file.bmp");

C) STL - Never used it, so cant help there

* - Doesn't currently work with DarkSDK
** - Requires a lot of extra work to get it working with DarkSDK

Using STL




Much easier than all that strcpy stuff, much smaller than the MFC stuff (quicker than MFC too), and works fine with the sdk .

I use (std: <string> and <stringstream>, works perfectly.
(also converting integers and floats to strings is really easy with stringstreams, << and >> operator )

ps: you need to convert to char* (LPSTR) if you want to pass your string to a DGDK function.

macro string2lpstr

sprintf(), why does everyone over look it x.x

assuming filepath contains "file.bmp" or whatever:

sprintf(temp, "\\%s", szFilepath);

lots of formatting options usually make sprintf my favourite choice for building strings from data.

Considering I use it a lot, its odd that I forgot it...

The security enhanced version is sprintf_s(temp,sizeof(temp),"\\%s",szFilepath);

The appearance of sprintf scares me, it just looks ugly and confusing hehe
My favourite is still std strings and stringstreams.
