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: How do you open Sub- UDF from parent UDF

    G, I do not disagree.

    John was using the msg boxes only during testing. His design called for the use of xdialogs to display info to the user and collect additional input required to complete the calc. He encountered the same endless loop there.

    He and I have talked about alternatives that might give him better control and more flexibility. His idea of using a simple calc display field and do data entry using the embedded browse is not working. Turns out his calculation depends on a wide variety of factors and can be pretty complicated. I've recommended entering the rows one at a time using a separate form based only on the child table.

      G,

      Both of the Mg_box(), If case and Else case. It runs endless, over and over, from start to end of record again.

      Here the ZipFile

          G,

          The general problem is this. Can a calc display field (defined in form) call a UDF that sometimes needs user input through the keyboard to perform its calculations, when that field is being displayed in an embedded browse on a set based form?

            If the question ended here, the answer is yes.

            My inclination is to say no pending further testing.

              I admire how you put the question so succinctly. Sometimes the lawyer in you comes out!
              My inclination was correct. The answer is no.
              Just tested it. It is a struggle just to get that calc value field in the browse and yes, it will go in endless loop. it is, I am assuming, running through all records in the child table. I have to run.. I have an alaram bell going off. later...

                Tom and G.

                Thank you for your effort on my problem.

                I still have the trouble using my UDF on a Form which one table.

                I started over from scratch. I created an xDialog and inserted that UDF at end of xDialog. It runs well and manipulated much better than Form base. I could not figured this small problem out. The Problem is that vEstQty did not share or transferred from Main_xDialog to Convert_xDailog. I expected this vEstQty suppose be transfer to the other UDF.

                I called "Dim Shared vEstQty as N"
                Code:
                         'This is Main_xDialog  
                          'void full scripts, shown only portion
                
                         if a_dlg_button = "vPrdid_changed" then
                		    'Run UDF to calculate the POqty
                		   ' dim x as p
                		   ' x = local_variables()
                		   ' vPoQty = Old_EstPoqty_calc(x) '(vPrdId,vEstQty,vEstUom)
                		    
                		    vPoQty = Old_EstPoqty_calc(vPrdId,vEstQty,vEstUom)
                        end If
                Code:
                        'This is Convert_xDialog  
                          'void full scripts, shown only portion
                        FUNCTION Old_EstPoqty_calc AS N (vPrdId AS C,vEstQty as n,vEstUom as c)
                           'Same as others ...
                          'Coverage xDlg
                	vCover_result = ui_dlg_box(dlg_title,<<%dlg%
                	{on_key=enter}
                	{lf};
                	{region}
                	Current Product is:| [%R%.35vSeriesName];
                	Convert Ruler Type:| [%r%.15vRuler];
                	Estimated Quantity:| [%Z%.20vEstQty!vSize_*];
                         'void to show
                
                        end function

                  Never mind, It works well after re-open the A5.

                    In your function you run a query and then retrieve a field value from the "found" record. That "found" field value is then used in your IF.. ELSE..END IF code block.
                    This will not work because the script in your function DOES NOT WAIT for the query to be completed before executing (or attempting to execute) the statements which follow. Instead, the query is run in a separate thread, and the script continues to run without stopping until the query has finished. In your script that means the variable vMbrType has no value... indeed it doesn't even exist... when the IF..ELSE..END IF code block begins.
                    -- tom
                    Seriously Tom
                    Does this mean as it appears to, that using these two statements;
                    - qSer = tSer.query_create()
                    - rSer = tSer.Records_get()
                    a result will not or might not be assigned to rSer because the .query.create() runs in its own thread and the second statement will execute in the meantime?
                    Or am I misinterpreting?

                      Re: How do you open Sub- UDF from parent UDF

                      Ray, that has not been my experience. rSer will get a value, but only after the query has run. However, I have seen cases where LATER statements were executed before the query completes. This is most often encountered when users build scripts that run one batch operation after another, expecting the script to wait until all previous opns have finished. That's not the case here, obviously, so perhaps I misspoke. Still, it's something I've learned to check.

                      I do not think John was having a timing issue in his script. Instead, I think his problem stems from the interaction of his message boxes and the calc display sequences in his form.

                        I get you
                        I shall take it as a heads up for one other option to check for when something's not appearing to work reliably.

                        This post turned out to be quite enlightening for me all round.

                        Thanks all concerned.

                          G,

                          x=local_variables()
                          vConvQty=Est_Indirect_poqty(x)'
                          Can you tell me more about the "Local_variable" application?

                          I read about the Local_variable from help files. However, I still not have any Idea to apply it.
