Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    This "filefind.get" and loop should work, I think...

    Good day,

    I am simply trying to loop through a file list created by the filefind.get function, but the "files.eof()" is not recognised and displays an error message. Please advise what is wrong with the code below?


    files = filefind.get("C:\*.txt")
    while .not. files.eof()
    'DO SOMETHING INTELEGANT HERE
    files.next()
    end while

    Regards
    George

    I think files (the variable) ends up as a crlf delimited string, whereas .eof() is a file function...

    We use *for_each() to process crlf lists generated with the same function.

      George, your script assumes there are some TXT files in the root directory. Are there?

      "...displays an error message" covers a lot of ground. How about giving us the exact message?

        Try this instead -

        Code:
        file_list = filefind.get("C:\*.txt")
for each file in file_list
'DO SOMETHING INTELEGANT HERE
     ui_msg_box("File is",file)

          Also you will find that changing
          Code:
          while .not. files.eof()
          to
          Code:
          while .not. files.[COLOR="Red"]fetch_[/COLOR]eof()
          usually works much better than just eof

            Attempting to use fetch_eof() with a character string will generate error #16000;Not found;files.fetch_eof method not found.

            Since filefind.get() returns a character string you need to use character string processing procedures instead of table processing procedures.

              Andrew, thanks for that---first time this fact has appeared to me in all the times I have read about .eof not working whereas fetch_eof usually does. Now it makes sense!!!

                  Code:
                  files = filefind.get("C:\*.txt")
while .not. files.eof()
                  You are trying to mix oil and water, and they do not mix.

                  fielfind.get() is a function that goes to your DIRECTORY and collects a list of FILES that match certain criteria.

                  eof() and
                  fetch_eof()

                  are functions that goes into your TABLES and fetch RECORDS.
