Temporary Filenames using Windows API Calls

Kent Behre #1 / 4	Temporary Filenames using Windows API Calls Could someone tell me how to make a temporary file like Windows does in the TEMP directory. I found an API call "GetTempFileName", I can't seem to get it to work though. It creates the "temp" file in the /windows/temp directory but I can't seem to get the filename that was assigned by the "GetTempFilename" function. Any help would be appresiated greatly! Kent D.

This function puts the new filename in a buffer you provide. Before the CALL, initialize the buffer to SPACE$(80) or so. Quote: >Kent D.

It should work. Have you declared the function right? (You can find it in the Win31api.hlp file Declare Function GetTempFileName Lib "Kernel" \ (ByVal Drive As Integer, ByVal Prefix As String, ByVal Uniq As Integer, \ ByVal TempFileName As String) As Integer Arguments are: Drive The Drive to put the temporary file on. If 0 Windows will use the TEMP variable. Prefix Set it to a string you would like to use as a prefix (1-3 chars and NUL terminated) Uniq If 0 instructs Windows to ensure a uniq name, otherwise Windows will use the value of Uniq as the number. TempFileName Name of file created Remember to create the space for TempFileName before the call, e g TempFileName = string$(255) and to NUL terminate the prefix if you are using it. Hope this will help! /Fredrik

Try thi sit works for me... Const TF_FORCEDRIVE = &H80 'Drive is the first character of the path... sDrive = UCase(Left(sPath, 1)) 'Force drive we want to be used... nDrive = Asc(sDrive) + TF_FORCEDRIVE nUnique = 0 'Change current directory on specified drive to config file value... ChDir sPath 'Call Windows API function... nRtn = GetTempFileName(nDrive, sPrefix, nUnique, sTempFileName) 'Strip off the '\0' sTempFileName = Left(sTempFileName, InStr(sTempFileName, Chr(0)) - 1) 'Strip off the drive... sNewFileName = Trim(Right(sTempFileName, Len(sTempFileName) - 2)) PZ Calgary AB
