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.

    tree control dialog opens with expanded node

    I thought I had seen the answer to this somewhere in the past but can't find it. Is there a way to have this tree control open with the first node expanded?

    Code:
    images = <<%dlg% 
    #$$folder
    %dlg%
      
    list = <<%dlg% 
    1+1Category1.1item1 
    1+1Category1.1item2 
    1+1Category1.1item3 
    1+1Category1.1item4 
    %dlg%
      
    ui_dlg_box("Tree Control Images",<<%dlg% 
    [%S=BLR;I=@images%.30,15item_selected^<list]; 
    %dlg%)

    Re: tree control dialog opens with expanded node

    You only have one node. To select the first item in that node.....


    Code:
    images = <<%dlg% 
    #$$folder
    %dlg%
    item_selected = "1Category1.1item1"
    list = <<%dlg% 
    1+1Category1.1item1 
    1+1Category1.1item2 
    1+1Category1.1item3 
    1+1Category1.1item4 
    %dlg%
      
    ui_dlg_box("Tree Control Images",<<%dlg% 
    [%S=BLR;I=@images%.30,15item_selected^<list]; 
    %dlg%)
    There can be only one.

      Thanks Stan. I tried that with "Category1" but didn't think about putting in the entire node code value.

        Glad you brought this up - I was working on a tree dialog today. Using Stan's example, try this to omit the boxes and just have your images

        Code:
        images = <<%dlg%
        $$navigate.down
        $$navigate.next
        $$code.debug.line.current
        %dlg%
        list = <<%dlg%
        2+1Category1.3item1
        2+1Category1.3item2
        2+1Category2.3item3
        2+1Category2.3item4
        2+1Category3.3item5
        2+1Category3.3item6
        %dlg%
        item_selected = "2+1Category1.3item1"
        ui_dlg_box("Tree Control Images",<<%dlg%
        {removecomments}
        '{wrap=40}
        'Images:;
        '[%O={I=:1} {@#}%.30,7mage_name^#images];
        {lf};
        Tree:;
        [%S=L;I=@images%.30,15item_selected^<list];
        %dlg%)

          The principle, as I think I understand it, is that to pre-set the initial chosen value in a list variable of any type is to set the value of the return variable before the list is displayed. In this instance the item_selected variable control displays values established in the list variable.

          [%S=L;I=@images%.30,15item_selected^<list];

          To preselect one of the values from the list variable we simply set an initial value for item_selected.

          To make the code a bit more generic one could use

          item_selected = word(list,1,crlf())

          to pre-select the first value in any list in any dialog where "list" is the choices variable.
          There can be only one.

            Thanks Stan that is a much better way to set the opening choice.
