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.

    Display argument help when using a UDF

    When one creates their own function, how do you display the help below each argument like the built in functions.
    I know it can be done as I did it a long time ago but I can't remember the code needed.

    Thanks

    You have to use the same parameter name Alpha would use in a similar function. If you want the argument to have help/allow select for a file name you should use filename as the parameter.

        Another avenue is to edit the AllFunctions.txt in the FunctionHelp directory under the Alpha program directory and add an entry for the udf. The parameters will appear as you create in the entry. Alpha doesn't read that file until you close and reopen. The entries thus created are available to auto-complete for every instance of Alpha whether or not the udf exists or not.

          Thanks for the responses.
          I'm having a little trouble wrapping my head around what I have read.
          Specifically, I want to add a simple help statement as to what to enter for each argument.

          I think what Allen has done is what I'm looking for.
          Allen, I can't seem to get your functions through drop box. Would it be possible for you to attach the text file to a post?

              Thank you Allen.

              Mozilla wouldn't let me get the file from dropbox. Kept getting a message "Your Connection is not secure"

              Anyways, After 2 minutes looking at your functions, I found what I was really looking for.

              Code:
              FUNCTION alt_param_test AS C (bxdesign as n=0,fsize as c="8",color as c="red",font as c="arial,9")
              	'DESCRIPTION:A UDF to show bubble / popup help
              I was looking for the line 'DESCRIPTION: then my instructions

              Thanks again

                My understanding when you add the 'DESCRIPTION: section is that it should be all caps and left aligned not indented. But if that works for Allen it must be ok.

                  Just some additional info.
                  'description: will work as well...completely case insensitive. Just has to be the very first "word" on the line after the Function....single quote prior and colon immediately after. Text after does not have to be right after the colon...can have spaces. And does not have to be left aligned...only has to be one "word" ;ie. 'description:
