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.

  • Record List Combo Box with Active Link SQL

    I have a set that contains a table called work order (dbf), and a table called depot (dbf) and a table called Vendor which is an active link table to a SQL Server Table. Work Order is the primary table, depot is linked to workorder on a field called DPONumber and Vendor is linked to depot on a field called VendorID. The form has a Record list Combo Box called Vendor. It is set up with the data to be the vendor active link table and the display field is name and the data field is VendorID. The combo box itself works fine in that you can select a vendor ACME Products for example, and it will put that vendors ID # (123 for example in the database). If you save the record and look at the table everything looks fine. When you open the form and pull up the same record, the record list combo box displays the first record in the drop down. But if you look at the underlying table the correct number is in the field (123). I added some type in fields on the form. One was the same field VendorID that was a type in field. The type in field displays the correct number but the combo box still shows the first record in the list in the vendor table rather than the record that 123 points to which is ACME. I went further and added additional fields from the vendor table and they all display properly. In fact if you change the vendor, the additional fields such as address and telephone change to that of the new vendor. The record list combo box will also show the correct vendor name after the change. However when you close the form  reopen it  and then select that record, it has the same behavior as before where it only displays the first record in the vendor table and not the vendor that is actually assigned to the record. Again the type in field that points to the same field (vendorid) shows the correct id number as well as the address and telephone which come from this same child table in the set all display fine.

    It seems that for reasons I can not understand that Record List Combo Box will not display the correct “choice” when used with an active link table. Note that I never see this problem when using this type of control with all DBF tables. I actually have several controls where I am seeing this problem however.

    Any help would be greatly appreciated

    Additional information: A regual combo box works fine, under the same scenerio. The problem with a regular combo box though is that it doens't deplay the "choice" it deplays the underlying ID.

      Hi Dean,
      Is this for desktop by any chance?? As this is a web forum, I was only going to just read it as I have not done much on the web side....could also be the reason others have not chimed in as well.

      Anyway, if a desktop question I don't understand
      The problem with a regular combo box though is that it doens't deplay the "choice" it deplays the underlying ID.
      You can choose whatever field or expression you want to display. Regarding the Active link useage of the Record List Combo Box I do not have a clue as I do not use Active links yet.
      It is only when we forget all our learning that we begin to know.
      It's not what you look at that matters, it's what you see.

        You are correct. It is for a desktop application. I'll have to repost it.
