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.

Validate event questions ....

  • Validate event questions ....

    In the Validate event of a dialog, I have the following:

    if val(CurrentForm.Controls.ptexp.value)>val(CurrentForm.Controls.fee.value)
    CurrentForm.Has_Error = .t.
    CURRENTFORM.ERROR_MESSAGE = "Ptexp ("+CurrentForm.Controls.ptexp.value+") cannot be greater than Fee ("+CurrentForm.Controls.fee.value+")!"
    end
    end if


    In the form, I put values of 150.00 for Fee and 220.00 for Ptexp. When I click Submit, the form does NOT display the error. I have been looking at this for hours. What am I doing wrong?

    You have to put the word "Then" at the end of the condition.

    If (<condition>) Then
    Statement(s)
    Else
    statement(s)
    End If

      EZ: "then" is assumed and can be left out.

      Gary: your formula works exactly as copied from your example in my test. Works whether the data type is numeric or char.

        Steve,

        I would think it should, but oddly enough, it does not.

        While this does not work:

        if val(CurrentForm.Controls.ptexp.value)>val(CurrentForm.Controls.fee.value)
        CurrentForm.Has_Error = .t.
        CURRENTFORM.ERROR_MESSAGE = "Ptexp ("+CurrentForm.Controls.ptexp.value+") cannot be greater than Fee ("+CurrentForm.Controls.fee.value+")!"
        end
        end if

        This does:

        if val(ptexp)>val(fee)
        CurrentForm.Has_Error = .t.
        CURRENTFORM.ERROR_MESSAGE = "ptexp+") cannot be greater than Fee ("+fee+")!"
        end
        end if

        Does this make any sense to you?

          Isn't there an extra "end" statement here?

          if val(ptexp)>val(fee)
          CurrentForm.Has_Error = .t.
          CURRENTFORM.ERROR_MESSAGE = "ptexp+") cannot be greater than Fee ("+fee+")!"
          end
          end if

          I would still put the "Then" in, just for clarity.

            E.Z.

            I never use "then" in an if statement and have never had a problem over the years.

            I also tried the code with and without the "end", and still, only the second set of code works.

            Thanks for your thoughts ....

              Gary,

              I once had a situation where val() didn't work, but convert_type( ,"N") did. Just for fun, you might try that.

                Hi Pat,

                As strange as it may seem, the only way I get this to work is with ptexp, fee, etc, not with any currentform.controls etc

                I tried the following just to see:

                if convert_type(CurrentForm.Controls.ptexp.value,"N")=200.00
                CurrentForm.Has_Error = .t.
                CURRENTFORM.ERROR_MESSAGE = "Hi Pat"
                end
                end if

                I put a value of 200.00 in the ptexp field, and it did not work.
