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.

    Hi Guys,

    The following script copies the previous years data into a new dbf that is named Y+previous year's year. Example in about February 2001, if the script is run, it will copy all data for the year 2000 into a new dbf named Y2000, then delete all 2000 data from the current dbf. Don't pay any attention to 1999_1.dbf, it is merely in the developement stage of this script and will be deleted in the final stage, it is a copy of another years data.

    What I need to do is to add a line after a-tbl.index_primary_put("lstfsmid") that will prevent editing when the table is viewed at a later date.

    a_tbl ="1999_1.dbf")
    new_name = "y"+alltrim(str(year(date()-365)))
    query.order = "lastname+firs_nam+midinit"
    query.filter = "substr(datepaid,9,2)=substr(new_name,3,2)"
    copy.set = ""
    copy.db = "c:program filesa5v4union"+chr(92)+new_name+".dbf"
    copy.dd = .t.
    copy.delete_o_dd = .f.
    copy.records = .t.
    copy.fields = 10
    copy.field1 = "lastname"
    copy.field2 = "datepaid"
    copy.field3 = "duespaid"
    copy.field4 = "assesspaid"
    copy.field5 = "percent"
    copy.field6 = "trade"
    copy.field7 = "dues"
    copy.field8 = "firs_nam"
    copy.field9 = "midinit" '20
    copy.field10 = "dept_num"
    file_add_to_db("c:program filesa5v4union"+chr(92)+new_name+".dbf")
    query.order = "lastname+firs_nam+midinit"
    ui_msg_box("Index","Index has been created.")
    a_tbl.close() 'line 35

    Any ideas,
    Thank you all in advance,

    Ed, I don't know of a way offhand to 'lock' a table in xbasic.

    In my own work I head changes off at the pass by making certain that the user can't get to the table except using a form which I provide... and that form is set to readonly.

      Thank you Tom, it's worth a try

        You could put a field rule on the backup database at the record level on the canchangerecord event that stops all changes.

            RE: not allow editing

            When I click on the button to run the following script to view a year in history I can press F3 to prevent editing (or changes). Is there a way that I can add F3 at the end of the following script ?

            dim hist_vew as c
            dim iwant as c
            hist_vew=ui_get_text("Which year?", "Enter the year")
            if hist_vew="" then
            end if
            if left(hist_vew,1)="y" then
            iwant=ui_get_file("Choose Table to View","Table(*.DBF)","","X")
            f=Browse.View("Default Browse for @"+iwant+"")
            end if

            Thank you in advance for your time,

              Hi Tom,

              Can a button be placed on the form to allow edits and new records?

                I do that on several of my forms. I've used the following script, attached to a button, to place a form in read-only mode:

                objfld = obj(":form_name")
                count = objfld.children()
                for i = 1 to count
                object = objfld.child(i)
                name =
                objtype = object.class()
                if objtype = "field" then
                object.field.readonly = .T.
                end if
                next i

                Everything on the form remains active, except for objects of type "field".
