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.

    CPU usage when viewing forms

    We have a simple "Main Menu" form tied to a one row/one column table that serves as a jumping off point to other forms. When this table is in the foreground, alpha5.exe uses 10% CPU. As soon as you switch back to the Control Panel usage drops back to idling levels, usually 0% on the Task Manager after a few seconds. Bringing any form to the foreground ramps up the CPU usage to at least 10% no matter how complex the form or underlying table/set is.

    This is on an Athlon XP 1800+ with 1GB of RAM. Our production database is on a network drive (Samba 3.0.22). CPU usage acts the same on the production database and my local test drive on C:. This problem can be replicated on any machine on our network.

    10% CPU just bringing a form to the foreground seems excessive. Any thoughts?

    I just checked on mine - when I go from one screen to another, the CPU jumps up, but after maybe a second, if its just setting there, it drops back to zero.

      Hi,

      Obviously has not changed much since V 5 then as my 1.4 ghz Athlon with 1 ghz ddr ram does about the same...spikes to about 24% CPU (or higher) when a form is first intiated, drops to 4% in a second (or less). Control panel in forefront spikes to 22% and then uses 1% after a second. When moving the cursor when anything but the control panel is forefront CPU will also spike to 20-30%. If the control panel is forefront, moving the cursor has no affect.

        V8 must be more efficient - moving the mouse on a form on mine is only maybe 1 to 2%

        Personally, I'm verrrrrrrrrrry happy with the cpu usage.

          Martin--I was using the form I am currently working on--apparently it does make quite a bit of difference (at least with V5) if it is a simple form like a menu with a few buttons or a much more complex one. My simple menu form does the same as yours whereas the more complex one does as stated previously.

          Guess it is always best to compare apples to apples.
