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.

  • Blank drop down on terminal server 2012

    We are moving to terminal server 2012. We are finding an issue with drop down fields on forms. About 50% of the time, the drop downs open and are blank. Pressing F5 populates the drop down.

    Has anyone ever seen this before?

    Have you tried sending a refresh to the control in its OnActivate event?

      I was hoping that some one else has seen this before I started programing some kind of work around.

        Ron, I have definitely seen it before but it was a long time ago and on Citrix rather than TS and may even have been on A5V5. It was very annoying. ultimately, I got rid of (almost) all drop down field rule lookups and replaced them with form events and lookup buttons. It was the only fix that worked consistently and was a big effort for an annoyance that should have been fixed by Alpha. It introduced a slight increase in user interaction but, since it worked, the complaints stopped.

          Thanks Finian. What's kind of weird is if I log in to the server directly and run the application, the drop downs work fine. When we have trouble is when we open up a virtual machine connection. Then about 50% of the time, the drop down is blank and we have to press F5.

            Re: Blank drop down on terminal server 2012

            Maybe someone can enlighten me as to what the difference is between setting the lookup drop down using the table field rules vs entering the lookup drop down using the field rules editor at the form level.

            I have the lookup set at the table level, yet when I check the field rules lookup at the form level, nothing is selected. I'm wondering if the lookup at the form level may fix the problem.

              Finian, The method you ended up with, did you do that to mimic the drop down? Or did the default browse option not work either.

              Robin, Tom Cone and I tried a number of ways to deploy the F5 key and nothing we tried would work.

                I use form level field rule lookups when I want to fill a field with one value but display a different value to the user.
                One thing I noticed when doing this is that you have to be sure to not only check the dropdown box but also select
                dropdown for the position.

                Which you probably already know - but I didn't! And of course it may not help with this particular problem but
                thought I would mention it.
