In vb6, making small games came with a curse, if you pressed more than one key at the same time, they would cancel out. I went around it by making a boolean array to determine which keys were up, and which were down. anyways,
View 1 RepliesI have several multi-line textboxes that I want to lose focus (i.e. when the user presses the right arrow key) but the control wil not relinquish the focus.Simply put, I first verify if the selection start is at the end of the text, if it is, and the user presses the arrow key, it should move to the next textbox. some debug.print code placed in strategic locations indicates that the target textbox gets focus and immediately loses it and the source textbox gains focus once again. Essentially not allowing the textbox to lose focus.
Select Case
Case Keys.Right
tbRight.Focus()

After changing the source textbox multi-line property to false, it behaves as expected. Is this a "feature" .. surely I don't have to resort to "SendKeys"

View 1 RepliesI'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

View 2 RepliesI have finished coding a VB.Net application that has connection to SQL Express 2008 database. My question is, what steps do I have to take to make this a multi user application.
FYI:There are 3 tables in the database of which two tables contain data to be viewed by the user and one table is to insert records by the user. The former two tables will be edited by the administrator only. So there is no issue of concurrency. But the one table that is used to insert records by all users has to be dealt with.
How do I make a multi user database?
Give me the logic, how do I achieve it?
For example, what file should the database be, where should I put the database(I prefer on my server), how do I encrypt the database.
Can I make it in columns? Username column and password column? My application then finds if any username match to the username inputted by user in my UsernameTextbox.Text then see if the inputted username and the password from PasswordTextBox.Text matches.
For now I'm using the If statement for both username and password. I have to write the same code again again for new users.
I want to about a multiuser application that have a server and 2 or 5 client to interect with mssql thorough application. how multiple cleint connect to database in same time.

I'm currently experimenting with a tile based dungeon crawler type game. When the WASD keys are pressed it will move in that direction, however if the key is held down it will move incredibly fast over the tiles, which is not what I want.Instead I want the player only to be able to move one tile at a time, or after each key press. Is there any way to do this with the KeyDown event or do I have to use KeyPress to make sure it only activates after each full key down & up?
