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.

  • Reports and Multiple select

    Hello everyone,

    I created a dialog with 3 fields, all set to Multiple Select.

    I find it complicated to construct the filter for the report but I managed to come up with this (and I'm sure there's a better/easier way)

    theyear = ChosenYear.dump()
    theyear = remove_blank_lines(theyear)
    theyear = *for_each(x,"Yr_Rec = " + x,theyear)

    psycho = ChosenPsycho.dump()
    psycho = remove_blank_lines(psycho)
    psycho = *for_each(p,"Psych_ID = " + quote(p),psycho)

    vschool = ChosenSchool.dump()
    vschool = remove_blank_lines(vschool)
    vschool = *for_each(s,"School_Id = " + quote(s),vschool)

    filter = (stritran(alltrim(invnum),crlf()," .or. "))
    filter = "(" + filter + ")"
    filter2 = (stritran(alltrim(psycho),crlf()," .or. "))
    filter2 = "(" + filter2 + ")"
    filter3 = (stritran(alltrim(vschool),crlf()," .or. "))
    filter3 = "(" + filter3 + ")"

    filter = filter + " .and. " + filter2 + " .and. " + filter3

    So my question is (other than a better way of doing it) how do I allow the user to choose ALL of the schools, or years, or psychologists?

    If I choose, say, a few of the schools by doing [click shift-click] then it works and I get multiple schools, if I choose all the schools I get an error of "incorrect data type". There are approx. 200 schools. I have tried choosing schools in groups of a-c, d-f etc to see if any of them were a problem but each group works fine, it's just when I multi-choose all of them.

    So, how do I allow a user to choose ALL?

    oh, I tried using an wildcard "*" but still to no avail.

    At the point that the filter string exceeds 1024 characters Alpha converts the string into a blob data type not suitable to the current endeavor. You will need to decide whether it is necessary to be able to select enough schools/years/psychos to exceed the string limit, or not, and act accordingly.

    IOW, if all schools are selected or enough to exceed the character limit, given the other constraints, warn the user and remove that portion of the filter.

    There can be only one.

      Thanks Stan. I'll try to work around it.

        Reposting from this thread (
        ) as I was in the wrong area:

        Hi Mike,

        I was thinking along the same lines. Looks like yours is for the desktop whereas mine is web. Anyway, here's what I was thinking of doing. Each of my tables will have a Selectrpt field and the Report criteria will be something like P_Psychos->Selectrpt="Y".AND.P_Schools->Selectrpt="Y". I would display a dialog where the user can pick the records they want to see in the report and once they click [Submit] I'd like for code to update the the Selectrpt field in each of the tables; that's where I'm stuck. I don't know how to do that and I just don't understand how the *For_Each() works no matter how many times I read the help file. If I use the *For_Each() how/where do I put the tbl.change code? I'm embarrassed to say how long I've been working on this one report. :o

        I hope someone can put me out of my misery on this.

          Still no joy on this although I have completed an ugly work around for now. I've added some code to the AfterValidate that checks if the user chose any psychologists, if not I add a filter that is sure to return ALL the psychologists (Psych_Id = -45 for instance). I did the same with the schools. So for now they can choose all or 1. I'm still stuck on how to allow them to choose say, 150 schools, 150 psychologists and years 2000 - 2009. Does anyone have an example they can share with me? I can't have them go through picking one by one :)

            Okay, I guess this can't be done or no one has attempted it. If anyone has done this can you let me know how you did it?

              Add selectable options in your dropdown for:

              - ALL -
              - ALL SCHOOLS -
              - TOP 150 SCHOOLS by SALES -
              - RANDOM 150 SCHOOLS -

              or whatever

              and then include code in your dialog to create a filter matching that option. Tell them to 'select one of these top four, or as many of schools as you like', or similar.

              Or if you want them to be able to select 150 or so specific schools, abandon your dropdown and shift to a page with checkboxes where they can select and "add" schools to the report or. Another way is to list all schools in a Grid along with any Search ability and include an AJAX callback button next to each school. The button would "add" a school to the print list. This is similar to how a shopping cart works. You click to add and build the list in another table. Then the print routine would reference that table. Make sure you cut off their ability to add once the number of selections is just under what the filter will allow due to length.

                Thanks Steve. I'm going to give it a shot with a grid and see what happens.
