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.

  • Prompt for a date variable problem

    I can't believe I am stymied by this one. I am using the "Prompt For a Date" action script genie to store a date into a variable "vprompt_date". I understand that it is a character variable.
    This happens in the "MM" or "main Menu" form.

    I then load a form:

    The onInit event of this form has the following code:
    vdate=ctod("var->vprompt_date")

    f = Form.load("reconcile","dialog")

    f:TABLES:xactions.filter_expression = "Date = {"+vprompt_date+"}"

    The form loads with an embedded browse that displays records that fit the date criteria.

    The browse has several columns that I would like to have totaled Spreadsheet style. To that end I have created several calculated fields that I have lined up under the browse columns.

    The expression in one of these fields is:
    dbsum("xactions","date","vdate","visa")
    Where "vdate" is a variable associated with the form.

    My problem is that vdate fails to take on the value of vprompt_date.

    vdate takes on the value of the current date which gives me the wrong total. I have an instance of the vdate variable on my form "reconcile" and when I change the date value to the correct date I get the correct sums on the bottom of the embedded browse.

    Re: Prompt for a date variable problem

    I believe you want

    dbsum("xactions","date",vdate,"visa")

    no quotes.

    "vdate" - evaluates to the name of the variable
    There can be only one.

      The string you sent me is what I am currently using and it works fine. The big problem is that the following code fails to transfer a date picked by the "prompt for Date" action script to vdate!
      I can't seem to get it to do it.

      The onInit event of the "reconcile" form has the following code:
      vdate=ctod("var->vprompt_date")

        Re: Prompt for a date variable problem

        Have you set the scope of the variable to make sure it can be seen by the form?

        The action script variable vprompt_date should be declared as shared or global.
        There can be only one.

          Re: Prompt for a date variable problem

          I set the scope to both global and shared and vdate still wouldn't take the string from vprompt_date.
          I was following the code in the debugger and I noticed that the system fails to transfer and values into vdate. Is there something wrong with the syntax?

          vdate=ctod("var->vprompt_date")

            Greg,

            from the interactive window:

            Code:
            dim vdate as d
            dim vprompt_date as c = "10\11\2009"
            var->vdate = ctod(var->vprompt_date)  'try with no quotes
            ?vdate
            = {10/11/2009}
            
            when you put quotes around it like this: 
            
            dim vdate as d
            dim vprompt_date as c = "10\11\2009"
            dim daysto as n
            vdate = ctod("var->vprompt_date")
            
            ?vdate
            = {  /  /    }

                  Didn't work. I even included the "var->" in front of the vdate. This is such a fundamental operation. That I can't believe it won't work.

                    This would be the code if you have all the rest set correctly

                    Code:
                    vdate = ctod(var->vprompt_date)
                    Where are you exactly using it? do you have the var->vdate properly declared and is it on your form? Are you refreshing your form?

                      Re: Prompt for a date variable problem

                      There are two forms involved. The first is called "MM" and I call up the "prompt for date" action script item. A calendar pops up and the user selects a date. The date is stored as a character string in "vprompt_date".
                      A form called "reconcile" is called up next using form.load which includes a filter that uses "vprompt_date as a parameter.
                      The oninit event of the "reconcile" form is supposed to load a shared variable called "vdate" with the value held in "vprompt_date.

                      A calculated field sums a column of numbers associated with the filtered rows. The expression is:
                      dbsum("xactions","date",vdate,"visa")
                      Sadly, "vdate" fails to accept the "vprompt_date" value.

                          This is in the onpush event of the "MM" form

                            Greg

                            Have been watching this thread and have been a little confused as to what you want to do.

                            I have attached a zip file that contains a dummy table and two forms named after the forms in your last post.

                            Open Form MM and press the reconcile button and select a date from the popup calendar , it will then open the reconcile form as a dialog and will pass the date to vdate in that form - it will show as the variable vdate.

                            Again I don't know if this is what you want -

                            If it is not then it would be a help if you could post a stripped down version of the tables and form so we could see what is happening and maybe solve your problem.

                              I found the problem but I don't know how it happened.
                              In the oninit event in the "reconcile " form I used action script to generate this code.

                              'Set the value of one or more variables.
                              DIM vdate AS D
                              var->vdate = ctod(var->vprompt_date)

                              I commented out the DIM statement and it worked. Not I am not certain about where the DIM statement is to occur.
