Err,
saptxt.Open("C:\My folder\temp_170807.txt",CFile::modeRead);or am I missing something here? -

hi, please mention the complete error... also,change the line to saptext.Open("C:\\My folder\\temp_170807.txt",CFile::modeRead); note the slashes...

hi swaroop double back-slash solved that problem... In the location C:\Myfolder i could have, lets say: temp_170807.txt temp_180807.txt, etc.... But only one file at a time will be present so i need to give a generic criteria like: C:\\My folder\\temp_*.txt Hope you got the problem

Well thanks Swathee i was putting single back-slash"\" double back-slash solved the problem...thnks[:)] but the problem of temp_*.txt still remains what can i do to get rid of this problem?? Program doesnt take temp_*.txt

What are you trying to do exactly?? you have to open files separately you can't open them in a bunch.

better u don use the multiple selection like this, use a CFileDialog class for that purpose, refer MSDN
swaroop
actullay by giving * wont solve ur problem, os else wat u can do is , if the file name ends with constant increase like temp_001, temp_002, etc just put the file open in a loop , concat the file name with the count (eg001,002) and open it and use it, don forget to close before u leave the loop:)

i m opening only one file at a time.... only one file at any given time will be present in the folder: C:\\My folder\\ i.e. i have either text_1000.txt or text_1001.txt in that location so i need to give something like text_*.txt i hope its clear...
I guess you will have to find the file name at runtime and then read it?!! There is a class called CFileFind MFC, you can use that,
CFileFind finder; finder.FindFile("C:\\Design Docs\\temp*.txt"); // this will find your file finder.FindNextFile(); // it is compulsory to call this function before you call GetFilePath CString filename = finder.GetFilePath(); // this will get the file name along with the path, so you can use this to open the file and read. finder.Close();Hope this solves your problem.
