why doesn't TRACE output correctly?

[liuyue]

CString strTemp strTemp.Format("%-60s%-20.1f\r\n%-60s%-20.1f\r\n%-60s%-20.1f\r\n","Global Wall",0,"Limiting Potential",0,"Roughness Correlation",0); TRACE("output:%s\n",strTemp); when debugging, the output is: output:Global Wall 0.0 (null) 0.0 ? -2.0 how can i dispose of the problem?

Remove "\r". Weiye Chen Life is hard, yet we are made of flesh...

Try casting your 0 to (float) 0 Now, they are int's.

[Blake Miller]

CString strTemp strTemp.Format("%-60s%-20.1f\r\n%-60s%-20.1f\r\n%-60s%-20.1f\r\n","Global Wall",(float)0.0,"Limiting Potential",(float)0.0,"Roughness Correlation",(float)0.0); // important to case the CString since the TRACE does not know argument type TRACE("output:%s\r\n",(LPCTSTR)strTemp);

All you need to do is replace each 0 with 0.0 instead. When Format() encountered the %f, it attempted to pop a float type from the stack but got an int type instead.
