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.

  • searching database

    I have a web based appilcation. The client wants to be able to enter a Sales number and then have the invoice of that sales number displayed in a new window. The client does not want this in a grid, so I have to use a dialog. I have ordered the XBasic Level I book, but they are out of stock and havenot yet received it, so I was wondernig what the syntax would be to look up a Sales record (by Sales Number) in an Alpha5 DBF table and then pass that Sales Number to the invoice web page so that the invoice can display the proper information.

    Re: searching database

    Jerry,

    Beautiful area up there in Vancouver! I'm down in Portland, and BC is one of my favorite vacation spots! Maybe this summer we can gather the Northwest Users and have a users group meeting at a winery in Vancouver!

    Before I get to your question, I need to say that it is a real tribute to Alpha Software that you can get a client and create software without knowing any Xbasic!

    I'm not sure if you mean that the selection dialog would be a dialog, or the invoice would be a dialog, or both.

    If the selection is a dialog, then you would only need one field and a Submit button. You have several options....if the user already knows the sales number, then it could be a text box. If they need other info to identify which sales number to use, then you could add a lookup.

    You probably don't need anything in the declarations, initialize and activate events. In the validate event you can check if they entered anything in the field with something like
    if alltrim(currentform.controls.SalesNo.value)=""
    Currentform.hasError=.t.
    Currentform.ErrorMessage="Enter the sales number"
    end if

    and check if they entered a valid number using
    if exist(....) -< check the help for use.
    Currentform.hasError=.t.
    Currentform.ErrorMessage="Sales number is invalid"
    end if

    Then, once you 've got a valid number, you have a couple more choices.
    One good choice is to put the sales number in the URL with something like
    vSN=alltrim(currentform.controls.SalesNo.value)
    Currentform.RedirectTarget="invoicepage.a5w?sn="+vSN

    Then in the invoice page, sn becomes a page variable. If that page contains a grid, then create an argument equal to sn and use the argument in the grid filter.

    If it contains a dialog, let me know and I'll give you some Xbasic for that.

      Re: searching database

      I have the search dialog, one control: SearchBox. The WtyNum is validated by the search field to make sure it exists in the database. If it doesn't exist it generates an error. That way I know the WtyNum is good if we hit the AfterValidate event.
      This is the code in its AfterValidate section:


      vgWtyFound = alltrim(CurrentForm.Controls.SearchBox.Value)
      Response.Redirect("wty_search_res.a5w?vWtyFnd="+vgWtyFound)

      This is the Arugument definition from wty_search_res.a5wcmp: aWtyFnd (Descr: value populated from a session variable named vWtyFnd)

      The filter: Wtynum=:aWtyFnd

      When I search for a wty that Iknow is in the database I get a grid in wty_search_res that is empty.

      Hate to disappoint you, but I'm actually right across the river from you in WA.

          Got it working. Don't really know how, which is scary. I think I finally flushed out the old file.

          Thank you very much. I really appreciated the simple solution.

            I'm regularly stopping the browser, flushing the history, cache to clean up during development and testing.

            IE is particularily fond of keeping and using it's cache instead of what I want it to use.

            IE is also much smarter than we are and uses it's interpretation of what the HTML code is intended to be rather than strictly what it should be. Mozilla (FireFox) does a more exact interpretation.
