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.

      Hi Ted.
      Here is some code. I took far too long for what it looks, but have tested it in your database with a couple of fields numeric and char.
      No validations. No filters. Just the create functionality
      Code:
      dim newtbl as c
      dim fieldlist as c = ""
      tbl = table.open("fld_data")
      tbl.fetch_first()
      NewTbl=tbl.tbl_name
      while .not. tbl.fetch_eof()
        fieldlist=fieldlist + tbl.fld_name+"," + tbl.typ_val +"," + tbl.length + crlf() 
        tbl.fetch_next()
      end while
      create_table(NewTbl,fieldlist)
      file_add_to_db(NewTbl+".dbf")
      I entered some new fields through your front end, then ran this code from CP
      One could further add fields and change field names later

          Re: ERD Diagram for Property Management

          Ray, couldn't get it to work.
          I ran it from a Form and also from the Code Editor. No errors, but no table either.
          Can you let me know how you ran it please?

            Re: ERD Diagram for Property Management

            When I got my first "biggie" I thought "Whoopie - Oh Bu66er - now I've got to do it!"

            My first "BIGGIE" was really a small app for Shell Oil Company and it was written in Clipper. I gave them a price for 3 months work. It was really done in 2.5 weeks and that was part time. Got lucky and sold the app to a second Oil company for the same price and a third one for considerably more. It all happened in about 4 months. Thought I was rich.

            LOL

              2. Open form. Enter Table name and some fields. Close Form.
              3 Run the code - The new table appears in the list and open for record entry.

                  Re: ERD Diagram for Property Management

                  It looks like your version is leaving spaces after the table name - only when adding it to the database.
                  try change
                  Code:
                  NewTbl=tbl.tbl_name
                  to
                  Code:
                  trim(NewTbl=tbl.tbl_name)
                  It would seem that the table has been created - look in your browser

                    It'sd created OK Ray, but you have to actually do and Add Table/Set manually.
                    Tried various coding options but getting the Table in the Current Db CP, is proving elusive.

                      Re: ERD Diagram for Property Management

                      I cant replicate the problem here - Many alpha5 operations use file_add_to_db()
                      It is may be to do with the relative table name in your database.

                      That will resolve with filename_decode()
                      Change the line
                      Code:
                      NewTbl=trim(tbl.tbl_name)
                      with
                      Code:
                      NewTbl=filename_decode(tbl.tbl_name)

                        Well we are getting there. (well with your help and persistence).
                        FILE_ADD_TO_DB("D:\Alpha 5 Test Bed\Alpha Test bits\DataDictionery1\my table.dbf") creates and displays the Table I want.
                        The [my table.dbf] is hard coded. How do I get the variable [NewTbl] in there instead?
                        Also, the Path to the Database could be optional?

                          FILE_ADD_TO_DB("D:\Alpha 5 Test Bed\Alpha Test bits\DataDictionery1\"+trim(newtbl)+".dbf")

                          Remember to make it generic in the case of the data dictionary creating the new table outside of the new database?

                            This is the final working version Ray. Why it didn't work the first time is probably the Decide line.
                            I'm going to add a few selection options using xdailog (sob) so I'll keep you posted.

                            dim newtbl as c
                            dim fieldlist as c = ""
                            tbl = table.open("fld_data")
                            tbl.fetch_first()
                            NewTbl=tbl.tbl_name
                            while .not. tbl.fetch_eof()
                            fieldlist=fieldlist + tbl.fld_name+"," + tbl.typ_val +"," + tbl.length + crlf()
                            tbl.fetch_next()
                            end while
                            NewTbl=filename_decode(tbl.tbl_name)
                            create_table(NewTbl,fieldlist)
                            FILE_ADD_TO_DB(NewTbl+".dbf")
