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.

    Re: To Wait (Synchronous) for a function to complete - then proceed

    I have a somewhat similar problem, but with xbasic code. I am using the File upload function to get data file from the user. I then use the 'After upload' to call an xbasic function to put the data in a holding table. the return from this first xbasic function is a message to the user that the data has been loaded. I then need to use another xbasic to call the validation processes (SQLServer stored procedure) that checks the data and moves it to another table. The second xbasic function returns a message that the processing is complete. THE PROBLEM: I can't figure out how to run the second xbasic function. When I call it from the first xbasic function OR make an xbasic function that calls both sequentially, the user never gets the intermediate 'Data Loaded, Please wait while processing' message. Any ideas? Should I post this to a separate thread?
    Include the call to the next xbasic function in the same code that displays the wait message.

      I can make an Action JavaScript Messagebox happen after the call to the first xbasic function (which is called from the fileupload Action) or I can put the message in the return JavaScript from the first xbasic function. I can not find an Action JavaScript that just calls an xbasic function and if I call the second xbasic function from the first xbasic function, the message does not get displayed until after the second xbasic function has finished. I don't know how to call an xbasic function with JavaScript.

        Use the Ajax Callback Action Javascript action to make an ajax callback to the server to execute Xbasic. You can create this as a javascript action and call it in the on close event for the message box, which is available when the Message box action is configured to use an advanced message box.

          Re: To Wait (Synchronous) for a function to complete - then proceed

          What I've got is so convoluted and it still doesn't work - the message is showing up before the file is even selected. This should be simple:
          Please help.
          What I need:
          1) Button for user to click to start process
          2) File upload ( I am using File Upload - User Defined Action called from the button)
          3) xbasic function to move the data into the 'upload' table (This xbasic is being called from the File Upload and works fine)
          4) message to screen to let user know that file has been uploaded
          5) another xbasic function that calls a SQLServer stored procedure that does the validation processing and puts the data in the Data tables.

          It works if I leave out step 4 and call the second xbasic function from the first xbasic function, but the users WANT that intermediate message.

            A suggestion:

            Let step 3 finish by opening a container window with the message, and an "OK" button or whatever you need. Open the window with this:

            Code:
            {dialog.object}.showContainerWindow(this,'WINDOW_UPLOADCONFIRM');
            Then, the click of that "OK" button closes the container window, and calls step 5.

            Code:
            {dialog.object}.hideContainerWindow('WINDOW_UPLOADCONFIRM');
{dialog.object}.ajaxCallback('', '', 'SQLCall', '');

                Good - did you use the method I suggested or some other approach? Posterity wants to know.
