break;ini file failing?
Author
Ok it will write the ini file if I do not put anything into the edit box im getting text from. when I do it fails yet the message box displays wat is in the array correctly. Once it fails it wont work again til I recompile the app completly. Closing and reopening dont work.

Also, if the text is longer than 256 bytes then it will cause a buffer overflow. You'd be better off to allocate 'test' using alloca, or something like that. Or you could use EM_LIMITTEXT instead I suppose.
Try calling GetLastError() when WritePrivateProfileString fails and see what the error code is.

hmm well I tried the error code thing. Ether it kept crashing trying to make the code readable or it would just print some weird stuff so i said screw it.

alright just tested and still same error now sure why. Hmm and could some show me how to get the proper error code even if I have too look it up. I keep getting some error. Dont link me to the example on msdn I read it and it confused me.
