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.

    xBasic basics: how to enter multi-line commands?

    Hi
    I need to create a big command (concatenating the values of 30 controls to create one long string).
    In vfp, i can do something like:
    myString = "somestuff"+"somestuff"+;
    "morestuff"+"morestuff"+;
    "evenmorestuff" ...
    What character do you use in xBasic to tell it the command is continuing in the next line?

    Thanks
    jaime

    myString = "somestuff"+"somestuff"+ \
    "morestuff"+"morestuff"+ \
    "evenmorestuff" ...

        I believe it's the backslash character

        myString = "somestuff" + \
        "morestuff" + \
        "evenmorestuff"

        I'm just too late today!

            You can also use this method to make your code more readable. It allows you to neatly enter lines of code and then execute them. Search for Code Indirection in the Wiki for other examples:

            somestuff = "steve"
            evenmorestuff = "Wood"
            morestuff = " "
            myString = <<%txt%
            somestuff + somestuff +
            morestuff + "a_literal_string" +
            " " +
            evenmorestuff
            %txt%
            ?eval(mystring)
            = "stevesteve a_literal_string Wood"
            Another example showing you can include xbasic:
            f = "steve"
            l = "Wood"
            fullname = <<%txt%
            upper(f) +
            ' ' +
            l
            %txt%
            ?eval(fullname)
            = "steve Wood"

              Hi Steve
              I am using your suggestion (%txt%) to create a long XML string, but i'm stuck at the following caveat:
              String looks like:
              Code:
              myXml = <<%txt%
               <?xml version="1.0" encoding="utf-8"?>
              <root>
              <tag1>blablabla</tag1>
              <tag2>upper(SomeVar)</tag2>
              </root>
              %txt%
              If i use ? myXml, then the xBasic functions and variables are not evaluated. On the other hand, if i use eval(myXml), it gives me an error - i guess because it's evaluating utf-8 as a variable. How can i have it evaluate the xBasic, but still format the string as "utf-8"

              Thanks
              Jaime

                Sorry, use evaluate_string() and use {} where I show below. I did not notice that my xbasic example actually failed.

                somevar = "steve"

                myXml = <<%txt%
                <?xml version="1.0" encoding="utf-8"?>
                <root>
                <tag1>blablabla</tag1>
                <tag2>{upper(SomeVar)}</tag2>
                </root>
                %txt%

                ?evaluate_string(myxml)
                = <?xml version="1.0" encoding="utf-8"?>
                <root>
                <tag1>blablabla</tag1>
                <tag2>STEVE</tag2>
                </root>
