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.

    Help With Dynamic Connections Strings

    I need help in understanding connection strings and if I am approaching this problem correctly, my application is an intranet app that at present does not use security and it is an information (lookup & reporting) app. I am limited to development in A5-V10.5 with most feature packs.

    I am reading against an existing package application that stores it’s data in Access .MDB files and uses a storage structure as follows. X:\Application_Dir = parent data and X:\Application_Dir\Client1 = customer-specific data. Now application Dir holds an MDB that is dynamic (Customers come and go) this database holds customer information and data directory associated with a customer I/E \Client1 or \Client2 etc.
    My goal is to use the Customer.mdb as a dropdown list to select the given customer then build the connection string based on that chosen. Again all that is changing is the Directory the connection string points to so in theory I would be doing a string substitution based on selection.

    Now the problem, I have searched the forum and read most threads on the topic of mutli-tenant applications and dynamic connection strings and have read most of the documentation I can find relating to this but it is NOT clicking. I am more of a procedural programmer C, VB, etc. where I can do this in an application based on variables but this is closed scope. In my test app, I am using a grid and setting the connection as SQL to access (not sure this is correct), then when I look at the source template header I can see the CS default connection setup and string and it is what I am expecting to deal with. Now is where I get fogged, I know I must somehow change the connections string and thus the connection session variable and do a refresh but I have no idea where to start or add. As a test, I would like to just use an input box to manually type the path and initiate data change and grow from there.
    Please understand I get the concepts but as with much of the online documentation it assumes you know more than you might ;-) and at this point that’s me and I’m stuck.

    Any help or pointing to good reading is more than appreciated

    I can't assist with your specific version, but can help with the topic in general. However, are you aware of the new community version made available? You could try working with it on there as it has more tools for dealing with dynamic connection strings. Just a thought. If not, I could assist you in general buy not on your specific version.

      No i am not aware of the new community version, what is it and what is it for? I guess I will have to start to dissect the supporting files to see if I can dynamically build the connection strings, many people build multi-tenant apps there must be an easy way that I am just not seeing. Thanks for your feedback

        Hi Rich,

        Here is the link to the new community edition. There is a built in dynamic connection string system now, in the newer versions.
