Question

I’m trying to check if a File Exists (INI)
If not.. it should create the File with the proper strings.

How do I that?

I tried..

s_text = “[DATABASE]” + “~r~n” + &

          "Server="   + "~r~n" + &

          "UserId="   + "~r~n" + &

          "Password=" + "~r~n" + &

          "DB="   + "~r~n" 

FileWrite(config.ini”, s_text)

but it says invalid argument to file

Answer 1

For testing if the file exist, there is the FileExists( filename ) that returns a boolean. That function only needs a file name to perform the check.

On the opposite, FileWrite() needs to work on an opened file. It is given a “file number” that is generated by a call to FileOpen() (and that file number should also be given to FileClose() at the end of the process).

Why not looking at the PowerBuilder documentation? There is a sample for that : from the PB IDE, press F1, look at the FileWrite PowerScript function section, then press the Example button. (Surprisingly, the example does not mention FileClose() but you DO need to call it ;o)

Don’t forget to check for invalid file numbers (for example if the file name does not exist, or if the file is already in use).

EDIT: as the OP clarified in the comments that he would like to be able to call SetProfileString() on a non-existing ini file (that cannot create a new ini file), here is an example of new ini file creation :

int li_file
string ls_ini = "config.ini"
li_file = fileopen(ls_ini, LineMode!, write!)
FileClose(li_file)

SetProfileString(ls_ini, "Database", "Server", "host") 
SetProfileString(ls_ini, "Database", "UserId", "foo") 
SetProfileString(ls_ini, "Database", "Password", "bar") 
SetProfileString(ls_ini, "Database", "DB", "baz")
