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.

    CONTAINSI can't see punctuation

    I have built a CONTAINSI expression as a filter for a FORM LOAD. I find that the expression can't pickup punctuation. var->lookup holds the string that the user is looking for. Partnum and description are the combined search fields. This works great although it can take 10 seconds to build the query. I just wish that it could find periods, commas and colons.
    Any ideas?


    f4=:formload("invent_pop","dialog")
    f4:tables:inventory.filter_expression=:containsi(partnum+description,'*trim(var->lookup)+"*')"
    f4:tables:inventory.order_expression=""
    f4:tables:inventory.query()
    f4.show()
    f4.close()

    BTW is there a way to speed up the queries by indexing the partnum+description?

    RE: CONTAINSI can't see punctuation

    Hi Greg
    Bored so I thought I would play around a bit with it. Honestly I have never used an expression they way you posted, however, you can get a query to find punctuations.

    Heres the scenario I made somewhat like yours:
    Built a dummy database with firstname, lastname (to recreate your dual field search). Also made a field called "index" which is nothing more than a calc field of

    alltrim(firstname)+alltrim(lastname)

    The first names are all periods, slashes, commas, colons, etc. etc. etc.

    On a main menu I have a button with this script for the push:
    dim global vlook as c
    vlook=ui_get_text("What are you looking for?","Enter it here")

    tbl=table.current()
    query.description="UserSearch"
    query.order="lastname"
    query.filter="smatch((index),'*'+trim(var->vlook)+'*')"
    tbl.query_create()

    f4=form.load("test2","dialog")
    f4.activate()

    Finds all the punctuation marks. Note its querying the "index" field. I don't know if combining the 2 fields would speed anything up, but figure looking in 1 field has to be faster than looking in 2.

    Maybe that may give you an idea on how to modify your script.
