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.

    Pass Variable to List Box control


    I am trying to pass a global variable from a UDF to a free form Xdialog listbox control.... & not having much luck. I have tried using ui_dlg_refersh() from the function but although I see the xdialog box refresh, the value in the control doesn't change. I am thinking that the change event of the xdialog control doesn't care about a change that takes place outside of the dialog. I tried using {watch=variable!change_event} but no help......

    Both the variable in the function & the listbox control have the same name.... Any help??

    Thanks doug

    RE: Pass Variable to List Box control

    here is an example that should get you started:

    Code:
    list=""%lst%
    {cat{T=1}mammal
    cucumber{T=1}vegetable
    cauliflower{T=1}vegetable
    carrot{T=1}vegetable
    dog{T=1}mammal
    dormouse{T=1}mammal
    cormorant{T=1}bird
    %lst%
    
    dim global one_choice as n
    g=global_variables()
    g.one_choice=1
    g.some_choice=1
    list=sortsubstr(list,crlf())
    
    dlg2="Dialog 2"
    ui_modeless_dlg_box(dlg2,""%dlg%
    {watch=g.some_choice!globalchange}
    Choose from this listbox:;
    [%O={@@}%.60,4g.some_choice^#list];
    
    "OK";
    %dlg%,""%code%
    if a_dlg_button="OK" then
       ui_modeless_dlg_close(dlg2)
    end if
    if a_dlg_button="globalchange" then
       ui_modeless_dlg_refresh(dlg2)
    end if
    %code%)
    
    dlg1="Make changes here"
    ui_dlg_box(dlg1,""%dlg%
    {position=expandright}
    Make choices here:;
    [%O={@@}%.60,4g.one_choice^#list!change];
    "OK";
    %dlg%,""%code%
    if a_dlg_button="change" then
       a_dlg_button=""
       g.some_choice=g.one_choice
    end if
    %code%)
