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.

  • xbasic message box or msgbox help

    how do I create an interactive message box from a server side event like onAfterSQLCommandExecute?

    In this event, I have logic that gets a count of records with a previous revision number and I want to prompt the user with a message:
    "Do you want to log out previous revisions?" Yes/No

    If "Yes", I have logic written to do an update on the matching records.

    The only thing I can't get to work is the message box. I've searched the board, help and wiki and all I can find are desktop message box examples and I am dealing with web version. What is the message box equivalent in xBasic? Is this possible?

    For example, I've looked at:

    1) msgbox("test","this is a test",UI_YES_NO)

    response = ui_msg_box("Question", "Do you want to log out previous revisions? ", code)
    if response = UI_YES_SELECTED then
    'Yes selected
    ' if user selects YES, update records with prev rev that have not been logged back in
    sql = "UPDATE docmgr SET log_status = 'Out', log_out_date = getdate() WHERE document_number = :doc_nbr AND document_type = :doc_type AND UPPER(company) = :co and log_status = 'In' AND revision <> :rev";

    but I can't find anything on web equivalent. please help!

    Re: xbasic message box or msgbox help

    You're confusing xbasic methods with web methods. The web (i.e. browsers) runs JavaScript only. You can use xbasic in callbacks and in server-side events. Server-side events run on the server, not the browser. What you have stumbled upon is one of the most difficult areas for desktop programmers to wrap their heads around (it was for me, certainly). The sequence of event timing, server vs. client (browser). The JavaScript equivalent to an xbasic message box is the alert() function. As in: alert('Hello World'). There's also a confirm() function. Alpha also has it's own JavaScript "message box":

    var vUser = {dialog.Object}.getValue('USERNAME');
    msg ='Delete User','<div style=\'padding:5px\'>Delete ' + vUser + '?</div>','yn',function(vChoice){
    You can't run this in an xbasic event, unless the event allows for it to be passed back to the server. You can always run it in a JS event. But even there it can be confusing since JS runs asynchronously. This is tricky stuff for sure.

      Re: xbasic message box or msgbox help

      Thank you very much Peter for your response. I am clear on where the server vs client side events run, but you are right about being confused about WHEN they run in relation to each other. I supposed that will come with time.

      Your post did point me in the right direction. I just had to add a session variable to store the value of how many records need updated from my server side event, published the session variable so I can then check if session var > 0 on the client side, display my alert. Thank you so much for your help! Have a great week!
