scenario: i will make database located in a server (LAN) and a multiple client that can access the server database to add,modify,delete records.Im not aware that building a multi-user application database is different from a normal one user application database. T_T.i read some guide and other walkthrough on building a database but it became confusing when it doesnt my requirements. coz when i try to open my database(.mdf) to connect from other client (in another station) it says its currently in use and connot connect to it. err. @_@..
I'm building a multi language application, but in the application, there will be some data that will be retrieved from the db. In the db I have two tables (Access Groups, Teams) the two tables are related, there are some groups, that have teams, example (sellers can belong to team 1, team 2, team 3...). The data that will change it's the names for the access groups and the names for the teams. The only way that I can think to do this, is to have the different values for all the languages in the code, or some auxiliar file, and when loading the application I'll truncate the two tables and fill them with the current language values. By the way those values never change...
View 5 RepliesI am currently working on a project for school in which I am trying to implement a multi user login on one of my forms. I have an internal database connected in which one of my tables contains the user-names and passwords. I have a For/each loop to search the table for a matching username/password before allowing access to next form. The problem is even if the username/password is correct, my message box still appears to notify of invalid credentials, but still allows access to other form. The problem only occurs when I implement two For/each loops. With one, code works fine. Can any one see what might be wrong?

View 2 RepliesI have a single instance VB 2010 application I know how to communicate with the next instances run through the StartupNextInstance application event. The usual way of working with this is parsing command line arguments of the new instance and continue execution of the old instance. What I would like to do is replace the running instance with the new one. Is there any way to do this other than disabling the single instance property ?

View 5 RepliesI am trying to implement image caching for a web application and I found some code on the Internet that implements an HttpHandler that does this. The code was in C# and since my web app is written in VB, I decided to convert the code to VB. I managed to convert everything except the following code (in bold):
public class FileExtensionCollection : ConfigurationElementCollection
{
public override ConfigurationElementCollectionType CollectionType
{

From what I can understand, the two properties above provide a way to access the FileExtension collection either using an integer or a string index. My problem is that I do not know how to convert this in VB.
