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() function

    This function doesn't seem to be working. I have a dialog box with a couple of check box list boxes and need to extract the date value for the list. Am trying the for each...next process to read through the list. Here is my code:

    This builds the list:
    Code:
    DIM SHARED vDates as C = ""
    dim vNights as n = 5    'var->glo_NightStay
    dim vDate1 as D = {07/26/2010}  'parentform:vArrDate.value
    dim vDay as c = cdow(vDate1)
    for i = 1 to vNights
    	vDates = vDates + dtoc(vDate1)+"  ("+vDay+")" + crlf()
    	vDate1 = vDate1 + 1
    	vDay = cdow(vDate1)
    next
    This is supposed to extract the date portion of each line:
    Code:
    dim vNewList as c = ""
    
    for each x IN vDates
    	vNewList = vNewList + left(x,10) + crlf()
    next
    msgbox(vNewList)
    Help on this would be greatly appreciated.
    Thanks.

    Code:
    dim vNewList as c = ""
    for i=1 to w_count(vdates,crlf())
     temp=left(word(vdates,i,crlf()),10)
     vNewList = vNewList + temp + crlf()
    next
    msgbox(vNewList)

      Martin,
      Well,,, that works. Now I've got to do some studying to figure out what this code is doing.
      Thanks a bunch.

        Re: left() function

        dim vNewList as c = ""
        for i=1 to w_count(vdates,crlf())
        temp=left(word(vdates,i,crlf()),10)
        vNewList = vNewList + temp + crlf()
        next
        msgbox(vNewList)

        since vdates is a variable with multiple entries with a carriage return at the end of each one
        w_count(vdates,crlf()) - gives you a count of the number of entries there are in the variable

        word(vdates,i,crlf())
        if i=1, it gives you the firt one, if i=2, the second one, etc
        left(word(vdates,i,crlf()),10) gives you the first 10 characters

          Ernie,
          I am not on a machine to test this right now but your original code will most likely work if use x.value in the left function. I don't know exactly why that is. I picked that up along the way sometime ago. And now when ever I use the For ... Each syntax I reference the each with .value with no problems.

            Super, Tim. Added the .value and it works. Don't know why it doesn't show that in the help. Only showed using "x".
