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.

        Since the field names are the same, as Robin's pointer suggestion but populate it with one command (even if not all the fields exist)
        Code:
        dim src as p  'pointer var
        source.get_record(src)
        target.enter_record(src)

                there are two options
                1> the data with the field name in a crlf format auto increment field should be left blank
                2> the data only
                that is what i understand.

                    Re: Updating table takes 5 sec in a local PC setup.

                    Yes of course these type scripts always work when you supply the value directly. But how does the string look if you want to map the fields from an open table or from form fields? Would it be like this?

                    - mapped from open table:
                    cs = <<%str%
                    name = t.Fname + t.Lname
                    addr1 = t.address1
                    ...
                    %str%

                    -mapped from open form
                    cs = <<%str%
                    name = Fname.value + Lname.value
                    addr1 = address1.value
                    ...
                    %str%

                    Cause if Record_Add() works like that - it will be my next favorite function!

                      Re: Updating table takes 5 sec in a local PC setup.

                      FWIW

                      Opening and closing tables is one of the prime reasons for slowness. This is exacerbated when connecting over a network.

                      Sequential reading of tables is another. - especially over a network...

                      Using some of the pre-built xbasic functions will open and close the table for each record add.

                      Writing your own function and keeping the table(s) open will improve performance a lot.

                      I like to use the append operation because it passes control to a c++ routine that is very fast if the filter for the transaction table is efficient.

                      Which leads us to avoiding the network flow of data by using a RDP or other remote connection (TSPlus) to really improves performance and reliability.

                        as far as the documentation, you are not supposed to use table.open and table.close methods with this function.

                        if you are opening and closing why bother using this function,
                        i am not sure there is any advantage.

                          Not as easy as I thought. You need to do variable substitution to get actual values into the expression.

                          Code:
                          t.fname = "Tom   "
                          t.lname = "Johnson     "
                          t.address1 = "123 Pine Ct     "
                          cs = <<%str%
                          #name = t.Fname + t.Lname
                          #addr1 = t.address1
                          #%str%
                          ? cs
                          = name = t.Fname + t.Lname
                          addr1 = t.address1
                          
                          cs1 =  strtran(cs,"t.Fname",t.fname)
                          cs2 = strtran(cs1,"t.Lname",t.lname)
                          cs3 = strtran(cs2,"t.address1",t.address1)
                          cs4 = strtran(cs3,"+","")
                          ? cs4
                          = name = Tom     Johnson     
                          addr1 = 123 Pine Ct

                            Ghandhi,
                            I am speaking about TWO tables, one already open as the source for mapping FROM in the string (right side) and the other I open as the target using this function (left side). That is why I asked how the mapping ought to look inside the string if I want to use this function. Assume t = table.current()

                            @ Stan: good!

                            @ Al : but this should be fast too since it is only one record being added.

                            As soon as I get the double click event in my browse functioning again, I am going to try it.

                              As the docs say...

                              Note : The RECORD_ADD() function opens and closes the table.

                              So the function is opening and closing the table itself. That's why is says:

                              You should not use TABLE.OPEN() or TABLE.CLOSE().

                              You can open a table and use the <tbl>.presist()

                              Normally, when a script ends, Alpha Five will automatically close any open tables. The <TBL>.PERSIST() method can keep the table open after the script ends, so that a subsequent script can access the table without the overhead of having to open it again.

                                Have you ever had a script close a table without having to explicitly close it? Cause I think I've got some timeshares you might be interested in... Hee hee hee
