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.

    that's great advice Stan as always.

    Re: Report to print specific dbf fields to text file

    Al, this should NOT be this difficult.

    We can help you faster with sample data to work with. If privacy is an issue, consider contacting one of us privately. My personal email is tom.cone.jr@gmail.com

    I would expect the following line:

    tbl.query_create("N","inactive<>'Y' .and. alltrim(dtos(Volcontrct))= ''","Name_sort")

    to return records where the inactive field does not have a "Y" in it, AND where the Volcontrct field is blank.

    The following line :

    tbl.query_create("N","inactive<>'Y' .and. alltrim(dtos(Volcontrct))<> ''","Name_sort")

    should return the records where inactive field does not contain a "Y" and Volcontrct is NOT blank

    Do you know how to use the interactive window to test filter expressions such as these?

    ' and "Volcontrct" field has a date...
    '
    'tbl.query_create("N","inactive<>'Y' .and. isnotblank(\"Volcontrct\")","Name_sort") 'Yields 2 BMs
    'tbl.query_create("N","inactive<>'Y' .and. isnotblank(\"Volcontrct\")") 'Yields 1 BM
    'tbl.query_create("N","inactive<>'Y'","Name_sort")' Yields 4 BMs
    'tbl.query_create("N","inactive<>'Y'")' Yields 1 BM
    'tbl.query_create("N","inactive<>'Y' .and. len(\"Volcontrct\")=10")' Yields 1 BM
    'tbl.query_create("N","inactive<>'Y' .and. alltrim(cdate(Volcontrct))= ''","Name_sort")'Yields 0 BMs
    'tbl.query_create("N","inactive<>'Y' .and. alltrim(dtos(Volcontrct))= ''","Name_sort")'Yields 0 BMs

    tbl.fetch_first()

    fil=file.create("H:\\A4Docs\PassVols.txt",FILE_RW_EXCLUSIVE)

    while .not.tbl.fetch_eof()
    tbl.fetch_next()

    In case it's not clear above, I've rerun each of the tbl.query_create lines above, then run my old basic program using the resulting text file, and then added a comment at the end of the query line, showing how many board members it found, of the 6 actual board members. The same basic program works correctly on an old Passvols text file created from the A4v8 version.

    Re: Report to print specific dbf fields to text file

    Al, when searching for blank date fields, I prefer to use the DTOS() function, instead of DTOC(), for the following reason:

    Code:
    [FONT=Courier New][SIZE=4]dim curr_date as D 
    
    ?alltrim(dtoc(curr_date))
    
    = "/  /"
    
    
    ?alltrim(dtos(curr_date))
    
    = ""[/SIZE][/FONT]

    Al, the msg board supports private emails. Check and adjust your profile to receive and send them. You can also specify your skype handle if you want. Many of us use skype to talk with one another. If you need additional help you can private msg me here. Or contact me on skype. - tom cone jr

    Testing blank date fields is probably better done another way.

    'tbl.query_create("N","inactive<>'Y' .and. alltrim(cdate(volcontrct)) = '' ","Name_sort")


    alltrim(cdate(volcontrct)) = '' <--two single quotes at the end

    Re: Report to print specific dbf fields to text file

    Agreed on the sort order, and I later found my basic program handles the order, so that doesn't matter here.

    The volcontrct was my terrible choice for a field name in this database, many years back. It really is the date on which our vols filled out our application form. Volcontrct really is a date field in the dbf, MO/DY/YR format.

    tbl.query_create("N","inactive<>'Y'")
    These are equivalent and return the same number of records but in different order.

    The first one that checks for blank volapps
    None check for blank volapps. They check for blank Volcontrct.

    This is working, sort of... Trick is it's not passing all of the records through that DO meet the requirements! I've tried various versions of the filtering part of the query_create line, and the one that's not commented out is the closest to working, but they all get less than the actual records they should. The first one that checks for blank volapps really clobbers the total number of records passed through, about half the number the other versions pass...

    is not what I gave you. Quotes inside quotes are verboten. See the documentation for backslash.

    Forget the table.order() line. Use the second suggestion if you want an order specified.

    tbl = table.open("APBVOLS")
    tbl.query_create("N","inactive<>'Y' .and. isnotblank(\"volcontrct\")","name_sort")

    Here is what I now have:

    tbl = table.open("APBVOLS")
    idx=tbl.order("name_sort")

    tbl.query_create("N","inactive<>'Y' .and. isnotblank("volcontrct")")

    tbl.fetch_first()
    '
    fil=file.create("H:\\A4Docs\PassVols.txt",FILE_RW_EXCLUSIVE)
    '
    while .not.tbl.fetch_eof()
    tbl.fetch_next()

    tbl.query_create line now has a red squiggly at front end with "Bad expression character" lurking when I roll over it...

    tbl = table.open("your_table_name")
    tbl.query_create("N","Inactive = 'Y' .and. isnotblank(\"VolAppDate\")")
    tbl.fetch_first()

    The rest stays the same.

    tbl.query_create("N","Inactive = 'Y' .and. isnotblank(\"VolAppDate\")"[,"optional order expression would go here"])

    Moving from the dos days to windows is a real trip in learning.
    As with most of the people here, I will extend help as you need it.
    Stan is a great help to ALL of us, but many of the things you will be required to do can be handled by using the tools to build your queries, reports, and more. Then you can have the option to get the xbasic code and modify it as needed or wanted. That is how many others do it and then show you the generated code as thought they wrote it(this does not apply to stan and some others).
    I am available by clicking my name and email or call me. I think it is posted.
