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.

    isnotblank - No Such Field?

    When using the isnotblank function in the filter of a browse, based on the set, I clicked on the Expression Builder, then clicked on the table, then clicked the isnotblank() function in the Functions list and then clicked on the field name from the table. When evaluating or saving the expression, the error message 'No Such Field" appears.

    I tried adding the table name but the same result.

    What's wrong?

    Thanks,

    Did you enclose the fieldname in quotes as the function requires? I believe if you "clicked the isnotblank() function in the Functions list" it will paste in "isnotblank(c fieldname)", indicating that that the fieldname must be a character string.

      Yes, that's what I did. The field name is in (). Does there need to be more than the field name? The function didn't indicate that.

            Stan,

            Yes, I figured that out and it is accepted. However, the filter is not working as all records are still showing; makes no difference if the field has data or not.

              What type of field is it? Date fields are tricky. see previous discussions.

                  Ken,

                  I remember having a similiar problem with the isblank() or isnotblank() function.

                  As an alternate way of accomplishing the same thing you can use:

                  Code:
                   for isblank() use: Alltrim(Fieldname)=""
                  Code:
                   for isnotblank() use: Alltrim(Fieldname)!=""

                    RE: isnotblank - No Such Field?

                    I suspect the problem is caused by something else. I've got a set, parent and child. There is a form based on the set which contains 2 fields from the parent table and an embedded browse form the child table.

                    The problem is that while in form view, not all child records will show. Example..if there are 12 parent records with child records, only 4 of the parent records will show the child records in the embedded browse.

                    I created a browse with the child as the parent and the parent as the child. Compared records and all child records (in the first set) have a parent record. The data in the linking field matches as well.

                    I also created a browse based on a new set, parent and child. As I scrolled down, I noticed that some parent records showed = to the number of child records. (Which is correct). So I checked the parent records only box and the parent records disappeared. (maybe that's supposed to be that way, I don't know)

                    I unchecked parent records only and put the following expression in the filter for the child table:

                    isnotblank("Account_Numbr")

                    Evaluate shows read past end of file but it also evaluates to false. Go back to view mode and the filter has no effect.


                    Any suggestions?

                    Thanks,

                    kenn

                      Vince,

                      I tried your suggestion. That didn't work either, even tried putting " around the field name.

                      Thanks,

                        Ken,

                        Here are two ways to do it.

                        Form Test1 evaluates the length of a trimmed field. Includes records in the display only if the trimmed length is not equal to zero.

                        Form Test2 uses the isnotblank() function.

                          Hi Tom,

                          Tried both examples and the same results, Message says Read past end of file but it evaluates to True or False. When I go to browse view, the filter has no effect.

                          I think there's something more here. If you could invent a magic wand to wave ofer the computer that would fix all unknown problems, well....you could retire!

                          Thanks,

                            Ken, one or both of your tables is empty. Put some records in there, otherwise there's nothing for the filter to work on...

                              Both tables have data. There are 1158 records in the parent table and 16 records in the child table.
