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.

    Newbie help with Login for Desktop Application

    I'm very new (less than 5 total days working time) to Alpha Five. I have experience using SQL Server and .NET but have been told I need to learn A5 (version 9). So I built a demo database to mess around with and get my feet wet. It's a student/professor/class layout (pretty simple).

    What I want to do is when the user starts A5, I want them to put in a username/password combination. That combination will tie them to a particular "user level" (in my example it's Administration, Student, Employee). Depending on that level, they will be permitted to only do certain things.

    I was thinking (again, this is coming from a .NET mentality) that I would set two variables (one logical (logged in or not) and one character (user type)). Then depending on those variables, the user will see a menu bar. If they are Administration, they can see everything. If they are a student, then can only see certain items (having the other items disabled somehow).

    I've included a .zip of the database (I hope I'm on the right path) and an example of what I was thinking of for the login screen.

    Is this possible? Extremely difficult? I've searched for "login" on the boards but most (all?) examples seem to point towards using the Web server. I'm not using the web server. Is this doable on the Desktop version? Is this most likely too advanced for a newbie? Also, I'm not really sure of XDialog, ActionScripting or XBasic - which would be more appropriate for what I'm trying to do? I was thinking I would just write a regular SQL script with a return value of 0 if no match or the userlevelID (1, 2, 3, etc) for a match. But I'm not really sure where I would write that.

    Any pointers, tutorials, examples, etc would be greatly appreciated. Thank you in advance for any help you can offer. In the mean time, I'll be working through the examples I can find online.

    Activate control panel and then look under tools->security and set database password. There is a built in function for controlling groups and users.

      Thanks. I didn't know about that. Hopefully it'll let me do what I was outlining. Anytime I can use pre-built functionality is a good thing :D

      Thanks again.

        John,

        Welcome to Alpha. We are glad you are here.

        There is an example of a login sequence that has more capabilities and is more robust, but also more complicated in this thread:

        http://msgboard.alphasoftware.com/al...ighlight=login

        Yes you can achieve what you desire. Look into the form OnInit events as a place to write code to handle the user types and direct the form objects.

          Hi John,
          Had to smile when I read
          student/professor/class layout (pretty simple)
          . :)

          Many times this ends up being a Many to Many to Many set relationship which can be handled but is a bit to grasp it right away (a student can have many profs and a prof of course can have many students---a prof can have many classes and a class can have many profs [does happen]---and last a student can have many classes and a class has many students).
          Mike
