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.

  • ui_get_radio2 question

    How can i trap the cancel button when using the ui_get_radio2 function?

    example:


    dim list as C
    dim res as C
    list = a5.Color_Enum()
    list = word(list,1,crlf() ,3)
    res = ui_get_radio2("Pick a color","red",list,"Color Selection")
    ' need to do something like this
    if ui_get_radio2_button = "Cancel"
    end
    end if
    ui_msg_box("Color Choice",res)

    Thanks

    I don't think the cancel button is returning the UI_CANCEL_SELECTED one might expect it to.

    How about eliminating the default value ("red"), which returns a blank value?

    Code:
    res = ui_get_radio2("Pick a color","",list,"Color Selection")
    
    ?res
    = ""
    Or, add another option to the top of the list?

    Code:
    dim list as C
    dim res as C
    list = a5.Color_Enum()
    list = "None" + crlf() + word(list,1,crlf() ,3)
    res = ui_get_radio2("Pick a color","",list,"Color Selection")
    
    ?res
    = "None"

      if res=""
      end
      end if
      If they do not pick something the response is "" (nothing)
      That is almost universally true in xbasic, a few exceptions of course

          There's an undocumented function that may be of help.

          UI_GET_RADIO2P()

          dim list as C
          dim tes as P
          list = a5.color_enum()
          list = word(list,1,crlf(),3)
          tes = ui_get_radio2p("pick a color","red",list)

          'if "Cancel" is selected it will be returned by
          ' tes.lastbutton

          'if "OK" is selected it will be returned by
          ' tes.lastbutton
          ' and
          ' tes.selected will return the choice user picked
