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.

    Creating install disk of shadowed database

    Let's see if I can make this clear. As a developer, I want to be able to create a custom network optimized database for a client, give them two disks (one to install on the server, the other on the clients), have them run the install files, and then be immediately able to run the program. This is easy to do if my drives match theirs exactly. But if they don't I need to be able to change the drive letter in the reference of the shadow .dbf files.

    For example, say I have a client who has a server F: drive. If I can map an F: drive, I can simply install the runtime on my F: drive and create the shadow in the F: drive under the A5V5Runtime\shadow folder. Then I can create an install file for the client machine by copying these files into an install routine and placing them in identical directories on the client machine.

    Now what do I do if I cannot create an F: drive? I would like to be able to create a different letter drive (say Z:), create the shadow as in the previous paragraph, and then simply change the reference in the shadow .dbf file. I tried doing this manually by opening the shadow .dbf file with notepad and changing the drive letter. However, this corrupts the file and it displays blank records.

    Is there a way to change the drive letter without corrupting the shadow table? Or is there a better way to achieve what I want to (assuming I was clear on that)?

    RE: Creating install disk of shadowed database

    Howard,

    If I understand you correctly, your problem is that you are trying to distribute the shadow database. Instead, you should have this as a routine in the main database to create a shadow based when needed. Normally, this would be if the user's computer has not been shadow initialized (which you can set a parameter in the user's private directory, A5 executable directory (or the worst place IMHO, the window's registry). Make sure the shadow routine copies other needed files that A5 does not normally shadow. See Cal Locklin's and/or my shadow routines in the Code Archive as an example.

      RE: Creating install disk of shadowed database

      Actually, Howard had a very specific situation where he knew exactly how the network was set up so it would be very easy to define exactly how the shadow should be set up.

      He found a very simple solution based on something that is in the Help file. His solution is discussed in this thread in the v5 section.

      In fact, I don't believe this capability existed when v5 first came out (although I could be wrong) and I feel a bit silly for not seeing it sooner. This routine eliminates the need for the Opt_net routines that Ira and I worked on.

        Cal,

        I guess I shouldn't have read these threads. Now I'm really confused.

        Does AlphaSoftware provide a step-by-step list of how to install an application on a network?

        Thanks I think,
        Jerry Gray
