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.

    Question about locate text script(form)

    Hi!


    I have made a script to be used in a form (triggered by button) where I can search for a productid, and if found the product's inventory are increased by a fixed amount.

    All this is pretty straightforward stuff I guess, but
    what I need help for is how to make the condition if a product is not found through the locate text , how stop the adding to the inventory.

    Could off course make to button scripts but I guess there is an easy solution.


    I have enclosed the xbasic for both locate text and the set field value from the code editor.

    Hope someone can help me.

    Regards
    Kim


    *********Locate text:

    'Locate Text in a field in a record in current form.
    dim pObj as p
    'get a pointer to the current window
    pObj = topparent.this


    dim TextToLocate as c
    TextToLocate = ui_get_text("Locate What","Select text to locate")
    if TextToLocate = "" then
    end
    end if

    if TextToLocate = "" then
    ui_msg_box("Error","You must specify non-blank text to Locate.",UI_STOP_SYMBOL)
    end
    end if
    dim tbl as p
    tbl = pObj.table_get()
    dim locateFlag as l
    locateFlag = tbl.fetch_loc_next(TextToLocate)
    if locateFlag = .t. then
    pObj.resynch()
    else
    ui_msg_box("Note","Text not found.",UI_INFORMATION_SYMBOL)
    end if

    *********Set Field values script
    'Set 'Value' property of 'Antall' in Form 'Untitled' .
    DIM form_name as c
    if is_object(topparent.this) then
    form_name = topparent.name()+".this"
    else
    form_name = ""
    end if

    DELETE expression_result
    expression_result = eval("Antall+1",form_name)
    topparent:Antall.value = expression_result

    The way I am reading your script, it seems that you will always update the value. Shouldn't you put the update value expression inside the if statement when you find the text you are looking for?

      I did'nt write the xbasic my self, I used the action script and justed copied the xbasic commands from them.

      And my problem was how to write it so it always doesn't update the value.

        What I am suggesting is that you take the code from the bottom of the script and insert it inside the IF statement.

        '********************** IN HERE!!! *****************
        locateFlag = tbl.fetch_loc_next(TextToLocate)
        if locateFlag = .t. then
        expression_result = eval("Antall+1",form_name)
        topparent:Antall.value = expression_result

        '********************** IN HERE!!! *****************
        pObj.resynch()
        else
        ui_msg_box("Note","Text not found.",UI_INFORMATION_SYMBOL)
        end if

        *********Set Field values script
        'Set 'Value' property of 'Antall' in Form 'Untitled' .
        DIM form_name as c
        if is_object(topparent.this) then
        form_name = topparent.name()+".this"
        else
        form_name = ""
        end if

          Hi!

          Tried it but get an error message, script:on pus line:29, expression_result=eval("antall+1,form_name), form_name not found

          This is the script in full

          'Locate Text in a field in a record in current form.
          dim pObj as p
          'get a pointer to the current window
          pObj = topparent.this


          dim TextToLocate as c
          TextToLocate = ui_get_text("Locate What","Select text to locate")
          if TextToLocate = "" then
          end
          end if

          if TextToLocate = "" then
          ui_msg_box("Error","You must specify non-blank text to Locate.",UI_STOP_SYMBOL)
          end
          end if
          dim tbl as p
          tbl = pObj.table_get()
          dim locateFlag as l
          locateFlag = tbl.fetch_loc_next(TextToLocate)
          if locateFlag = .t. then
          expression_result = eval("Antall+1",form_name)
          topparent:Antall.value = expression_result
          pObj.resynch()
          else
          ui_msg_box("Note","Text not found.",UI_INFORMATION_SYMBOL)
          end if

          Can anyone see what's wrong, my form is called h3, table h3, I want to use locate text to search the tables, and if found update the value in the record called antall with +1.

          Regards

            Since I don't know all of your field names and form issues, basically what I think is that you need to do whatever is necessary to fill the field IN the on true condition. If the "result_eval" code is not what you want to do, (and I really don't know what it is doing" then put code in its place to perform the specific task that you want.
