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.

  • Left trim ?

    Question, I know you can use left trim to reduce a field lenght.

    I want to take a "Character" Field which has a name and number. example: tom * 123456

    and trim everything after the * BTW I can not number eliminate the numbers, cause some names contain numbers.

    Does anyone know which function to use?

    Thanks,
    john

    Re: Left trim ?

    dim nme as c = "tom * 1234"
    dim nme2 as c
    nme2 = *word_remove(nme, 2, " ")
    ? alltrim(*word_remove(nme2, 2, " "))
    = "tom"

        I really do not know anything about qbuilder.

        There are other ways to accomplish the above. Some are simpler? This was quick just using help and not looking a whole lot.

          John,
          QRB is built upon Alpha and has almost every functionality it has.

          take a "Character" Field which has a name and number. example: tom * 123456

          and trim everything after the *
          The following assumes that there will only be one "*" in the string to be parsed....and that every record will have same.
          I take it as you also want the "*" included. So if doing this for all the data in a field:
          Code:
          Maybe word(your_field_name, 1, "*") + " *"
          or just for the example given:
          Code:
          word("tom * 123456", 1, "*") + " *"
          [/CODE]

                Here's yet another approach:

                Code:
                substr(a, 1, at("*", a)-1)
                This extracts a substring from the string in the variable named "a", beginning at position 1 and continuing to one position before the asterisk.

                And more simply:

                Code:
                left(a, at("*",a)-1)

                      Now that we know word() works to take out the characters to the right.

                      What do you change if you want to take out all characters to the left of a *?

                      Thanks

                        Re: Left trim ?

                        Use the appropriate word number (argument 2) or the number of word (argument 4)
                        WORD1.PNG

                        It may help to think in terms of what do I get rather than what am I eliminating... (it's always good to be positive..)

                          Re: Left trim ?

                          Thanks Al the problem I face is, the total words are not the same for each part number. I have one word which will always stay the same (Lot No.:) so I would like to take out all words leading up to the ":"

                          Example: USP 40-80 Mesh Packed in 50 kg. drums Lot No.: 1135
                          Result: 1135

                            Re: Left trim ?

                            Code:
                            a="USP 40-80 Mesh Packed in 50 kg. drums Lot No.: 1135"
                            
                            ?a
                            
                            ?word(a,1,":")
                            = "USP 40-80 Mesh Packed in 50 kg. drums Lot No."
                            
                            ?word(a,2,":")
                            = " 1135"
                            It took me a while to wrap my head around 'word()'

                            In this case the word count is not limited to the 'classic word' - ie there are not 11 words in your string when you delimited by ":" - there are only 2 - since there is only one ":" in the string...
