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.

  • Optionally disabled field

    I've tried searching the forum for this, but probably haven't used the right combination of words.

    Q: I've conditionally restricted entry to certain fields on a form using code on the CanArrive event; no problems there. But, is there any way I can conditionally change the appearance of certain fields, in other words to give the disabled (often called "grayed") appearance if the user doesn't have the required level of access?

    As far as I can see the ability to disable an entry form field is unconditional.

    Thanks, as always.

    That last bit should, of course, have read:

      Hi Martin

      If I understand you correctly you have different access levels for your users.

      If the user that is logged in doesn't have the correct access level you want to restrict their access to certain fields on a form.

      In the forms On Activate and On Init events you could put xbasic code that would check for the access level and disable the field and set the foreground and background colour for the field.

      You could also put the desired field in a conditional object that would hide the field.

        You can easily change the text color of background color of any object. When the form is activated, test for whatever condition sets access and use something like this for a text object

        if condition = .T.
        topparent:object_name.Font.Color = "Black"
        topparent:object_name.Font.Color ="Gray"
        end if

        For a field object

        if condition = .T.
        topparent:object_name.Font.Color = "Black"
        topparent:object_name.Fill.Forecolor = "White
        topparent:object_name.Font.Color ="dark Gray"
        topparent:object_name.Fill.Forecolor = "gray"
        end if

        You could also enable and disable the field at the same time

          That's perfect, Jerry, many thanks.
