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.

  • What is a .DBG file??

    Hi folks,
    I created an application in an earlier version of alpha (I think Alpha4) at least 5 years ago. I used runtime to keep the people here out of trouble. I converted it to alpha 5 version three and it ran both peer to peer and then on a server. When alpha5 ver 4 became available with network optimization I converted it to that. That must be at least a year ago. It has run without problems all this time.
    Last week we started to get error messages when trying to add a record to a small table, about 500 records in it.
    The message said ďunable to add key to tagĒ. I researched here and found solutions. I got rid of all the $$######.XXX files in the application and runtime folders on the PCís and then tried to run a rebuild index, which I had created a button for on a maintenance Form.
    I got a message that it couldnít find file Ölb.dbg. LB being the application name. I canít find this file anywhere. What is it??
    I was able to successfully run a pack, but I donít know if it ran the index rebuild. As of now, we still canít add records to that table, and I havenít worked with Alpha in a Looooooooooooong time.
    Any help, or reasonable advice, would be appreciated.
    Thanks in advance
    Vince

      Stan,
      should I be able to rebuild indexes through the shadowed files? Or should I go on the server and run the same application that resides with the real tables?

        If I understan correctly, shadowing/network optimizing brings down copies of the data dictionaries, etc to the local machine to speed loading of forms, reports and other layouts.

        The tables and their indexes reside on the server. Reindexing performed on a shadowed machine should affect the index files on the server.

          Got any ideas as to how I can determine why I might get the error message when I try to rebuild the indexes instead of success or get the "unable to add key to tag" message when trying to add a record, after all this time of no problems?
          Thanks again for your insight.

            Packing does rebuild indexes. (It removes any deleted records and once it has done this, the indexes have to be rebuilt - no check is done to see if there really records to be deleted)

            Why can't you use index rebuild from the workstation and add records?

            - What version Windows? How much ram? Run any diagnostics on the network interface card or swapped it out? Any recent changes to the network since the app was last used? Tried the app from a physically separate network connection point?

              Vincent,

              You could post a copy of the table the index here, so we could check it on our systems. Might turn up the cause for your problem.

              Have you upgraded to vers 4.5? The step from A5v4 to A5v4.5 included some fixes and enhancements to the indexing routines Alpha Five uses. Don't know if it will help in your case, but thought I'd mention it.

              You should search this forum for other threads discussing 'unable to add key to tag'. It's an error message that pops up when Alpha is unable to insert the next index key in the an index list. Can be triggered by anything which is locking the index file itself. Can be triggered by faulty expressions. Can be triggered by faulty data and simple corruption in the data.

              If this were happening to me, one of the first things I'd do is to shut down alpha five on all workstations and reboot the server to release any file locks that might be in place.

                One more idea.

                A table reindex requires exclusive read/write privileges to the table and its indexes. You don't say how you're doing the reindex (from a script, from the control panel, with other forms open, while others are working with the table... etc. and so on), so I thought I'd mention this too.

                  Tom,
                  It has been 5 years since I did any work on this thing except converting it several times to upgraded Alphas.
                  The last conversion was to A5V4.03 build 221.
                  I was running the index rebuild from a button on a form (I took all control panel function away from them in the App.) so I think it must have a script behind it.
                  I was on the only PC running. I guess I could have gone to the copy of the Application on the server through normal network mapping and run the copy of the App. on the server to see what happens.
                  I've brought a copy of everything home, over the weekend, to run on a fullblown version of Alpha rather than the runtime. I'll have to learn the App. and Alpha all over again.
                  What files of the table do I need to Post with the table, in case it isn't like trying to learn to ride a bike again ??

                    The workstation I was using only had the runtime application on it. Can't get to that control panel function. Built with A5V4.03 build 221. It fails same way from three different workstations. Which to me points back to stuff on server.

                      Vincent,

                      A patch was released in January, 2000. Current build for A5v4 is 230. Suggest you get it from the Tech Support page.

                      Suggest also you buy the upgrade to A5v4.5.

                      In the meantime the easiest thing to do here would be to zip the entire database if it's not terribly large. If you decide to send it to me by e-mail please include a 'readme.txt' file explaining which form and button is misbehaving.

                        I'm going to try running without the network on my PC at home, with the full blown Alpha tomorrow. I'll post my results.
                        I'll download the patch you recomend and discuss A5v4.5 with the folks who have the money.
                        I'll check the file size to see if it is realistic to send
                        Thanks Tom for the help.

                          Tom,
                          I installed the database application and runtime peice that I had copied from the server to a standalone PC here @home.
                          I tried to add to the table that had failed on the server and it failed here too. However, I was able to rebuilded the indexes, which I wasn't able to do via a workstation to the server. That fixed the problem.
                          I tried it peer to peer with runtime on one pc and database on other. That worked also including rebuild index with no error.
                          I also tried it network optimized without a hitch.
                          I then applied the runtime build 230 patch to the runtime peice and tested.
                          I copied both application and runtime to CD and copied to server. When I tried to access the database on the server from the runtime on the server, I got a nasty message about a multi user file.
                          I reinstalled the original files on the server applied the build 230 patch, rebuilt indexes with no multi user message, and it worked from the server. Updated the runtime on four workstations with the build 230 and they also worked.
                          I don't know how the multi user file got lost or where it resides, so I don't know how to make a standard method to fix this in the future.
                          It's working NOW though.

                          A big THANKS to You and Stan for getting me out of trouble and going in the right direction, and your offer of support with attached database.
                          Vince

                            "application and runtime to CD and copied to server" - depending on the windows version and software used to copy the files to and from the CD, the files may wind up marked as "read-only" and you will need to change that file attribute.

                              the muf (multi-user file) is created by Alpha Five. It's how Alpha prevents you from using more current instances of Alpha Five than you've licensed. The MUF file bears the same name as your database I believe, but has an MUF extension. You will encounter the error message if you try to start more copies of Alpha Five than you have licenses for. ... or if you crash during development and Alpha never gets a chance to erase the MUF file on the way out, during a normal shut down.
