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.

    Using Session Variables with Reports

    I am extremely frustration with myself that I have not been able to figure this out. I have read through many threads, but am still stumped.

    I have a report that requires both arguments and variables. I have a v11 dialog component that allows the user to set the parameters and variables. I have a button that uses action javascript to call the report, pass the arguments, etc. I have a submit button, but I do not know if I need it. In the report the variables are specified as session variables with a names like nMultiplier and cHowPrice. These variables are used in calculated fields in the report. They are defined in the report as nMultiplier=2.0 and cHowPrice="Retail". I am assuming these values are overrided by variable values passed from the dialog component. In the afterdialogvalidate (server-side event) I defined the following session variables: e.session.cHowPrice = e.DataSubmitted.pricing
    e.session.nMultiplier = e.DataSubmitted.multiplier

    Then I did a live preview and clicked the submit button (thinking that would trigger afterdialogvalidate) and then the report button. I get the report but it always has the variables as defined in the report (nMultiplier=2 and cHowPrice="Retail").

    I have no idea if my syntax is correct. Report Variables Dialog Variables
    nMultiplier e.session.nMultiplier
    cHowPrice e.session.cHowPrice

    I'd like to use one button on the dialog to call the report and pass the variables in the process. I was trying not to use global variables as a quick fix. Please point me in the right direction.

    Re: Using Session Variables with Reports

    If you want to pass a session variable to a report you do it through a calc field in the report.

    If your grid or dialog has: session.customer = "Smith"

    Then you report calc field would be: calcCust = session.customer

    Then you reference the calc field on your report, not the session vars. Remove the "session vars" from the report definition if you put them in the variable dialog box.

      Re: Using Session Variables with Reports

      Okay, I have the variables working now. Thanks. I'd like to program the submit button to do all the work on the dialog. In the server-side AfterDialogValidate event, I'd like to programatically click my report button. Is there a way to do this in XBASIC? or do I have to use the javascript AfterValidate event? I tried {dialog.componentName}.BUTTON_10003.onClick() in the AfterValidate event without any luck?

        Re: Using Session Variables with Reports

        You can do it w. an Ajax callback, i.e. xbasic function which returns the button's onclick in JavaScript.

        The return code would be something like this:

        ele = $('{grid.componentName}.D.V.R1._UNBOUND_BUTTON_1');
        ele.click();


        But I don't know you can do that directly from a server side event.

          Re: Using Session Variables with Reports

          It worked! My actual code was
          ele = $('{dialog.componentName}.V.R{dialog.rownumber}.BUTTON_10003');
          ele.click();
          which I put in the client-side event AfterValidate

          Now when I click the submit button the report is served up. Thanks for your help!

            Because the topic is the same but not the platform, I will try this question here off the above advice...
            I cant get this method to work for destop v10.5. Calc in report wont accept a variable it can't see. So I tried temporarily making a global variable to create the calc field. then later remove the global variable and call the form from the form.
            Ive tried also
            Code:
            dim SHARED vpFrm as P = topparent.this
            dim GLOBAL vnSH as n = vpFrm.SessionHandle()
            in the form - and in the report a calc field
            Code:
            var = session_variables(vnSH )
            but I just can't get some variable/objects for the report to inherit from the calling form
