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.

Post / Append to external database

  • Post / Append to external database

    I have 5 similar databases in 5 separate folders. Tablenames are identical in each database.
    All databases contain a table named Constransactions.dbf

    In one of these databases (NIMSInternational) users enter records that are uniquely identified by a field that designates which database they are to be posted to (so I know which of the other 4 databases is the target for the record).

    After a few records (say 100 or so) have been entered in the NIMSInternatioinal database, I want to 'Post' each record to the correct target database. This would be easy if all Constransaction.dbf tables were in the same folder in the NIMSInternational database... but the tables have the same name.

    I could leave the Constransaction.dbf tables in their individual folders and add all of these tables to the NIMSInternational database... then create Append Opperations... but since these tables are in different folders/databases this would make the app difficult to transport to other computers / drive letters C: L: K: etc.

    I could export the records as .csv or .txt from the NIMSInternational database and then individually import them back to each database... but I would rather have this happen automatically from the NIMSInternational database without user actions in the other individual databases.

    Is there a way to 'Post' these records from the NIMSInternational database to the external databases so that no user action is required in the individual (target) databases?

    Active-Link to .dbf table

    Is it possible to create an Active-Link (.dbf) table in one database that has a connection string to a .dbf table in another database on the same computer / drive letter?

    I have tried to create a connection string to enable this but I cannot see where I can enter a path or table reference... and ODBC data sources do not seem to work.

      Re: Post / Append to external database

      You could create a field rule event, probably for the cansaverecord, to add records to other tables. That would still require hard coding the drive letters and paths.
      There can be only one.

        Re: Active-Link to .dbf table

        ODBC data sources would work if you had a dbf driver. I don't think such is available these days.

          David

          Why an active link to another dbf? Active link is designed to connect to non-dbf tables.

          Add the dbf table to the database and point to the directory that it is located in.

          While most suggest that all tables should be in one directory, it is not a requirement.
          More of an ease of use for casual users/developers.

            If you work with this concept and create the append operations, then capture the xbasic for same, and modify the xbasic to reference A5.GET_PATH() instead of just using the tablename then you should be able to make the appends portable.

              Re: Active-Link to .dbf table

              Thanks Stan... I could not get any ODBC driver to work.

              Thanks Al... I will likely end up doing as you suggest... I will run into a few problems because I develop on a computer on the L: drive and deploy to a computer that uses the C: drive... bit of an inconenience... but I will work with it.
              although...
              I'm still toying with the option of Exporting each set of Transactions to an XL file in the NIMSInternational... then placing a button on a form in each individual database that enables the user to point to NIMSInternational and automatically import the XL file that is unique to the individual database.

                  Didn't work as well as I hoped...
                  The problem is that when deployed the target Constransactions.dbf table cannot be easily defined... A5.Get_Path() works ok for the Source file... but not the target:

                    I don't understand the reference to NIMSInternational.

                    It must be something that is involved in your application that hasn't been described.....

                    Is this a reference to what you described in this thread?

                      The Post about Active-Link tables was exploring the possibility of using them in an Append operation to solve the problem of posting from NIMSInternational to the other databases.
