But everytime i press a button to connect my program to the database i keep getting this error message Cannot open database "Northwind" requested by the login. The login failed.

I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

View 1 RepliesWhen I do the try/catch method in my vb.net project I will try the code I want and when it can't do it, i make a message box right after the catch method. The thing is that it will show the message box, and then another message from the program itself. Like for example, I have here a MySQLException, and when i click ok on the message box, it will show another one right after showing the exception itself. How would I be able to get rid of this so the user doesn't have to see this, and the program can continue.

But even when I do press control, the message box doesn't pop up.
I have a password form that contains a load of buttons. The user has to enter a four digit, numeric, password to procede. They do this by pressing one of 10 number buttons on the screen, the keyboard isn't used. If they enter the wrong password an error message pops up (this isn't using the error tool I just added a message box msgbox("Error Code #638492") or something) if the user doesn't enter a password, after 5 seconds (I use a timer called Timer1 with an interval of 5 seconds) the form closes and it goes back to the previous page.
My only problem is when I close the form using Me.close(), the message box is still displayed. And if the message box is still displayed it doesn't work. The form is miminized (I have the application in full screen) so this is very bad. What I need is to simulate the enter key press then close the form so the enter key is pressed, the messagebox close then the password form closes.I can do this using SendKeys.Send("{ENTER}"). Here's the sub I use:
[code]...
However, if I don't have the 'Close()' line of code in the message box closes as it should. If I don't have the message box open and I don't use the SendKeys.Send("{ENTER}") then the close() line works perfectly and close the password form as it should?
How would I do the following in Visual Basic Express?
a) Press "delete", "home", and "shift" on the keyboard with the program. // Still need to figure out how to do this.
b) Detect when "z" and "x" are pressed. // I'm using buttons instead of this part now.
I have a few questions:
1. how do I make a button press a certain button in another application? (i.e - for example it goes to application "iexplorer" and press insert, home, a, b, or other button in the keyboard)
2. How do I make a virtual keyboard (for example a button opens form 2 or 3 and when you click on a button in the keyboard it goes to a certain text box in form 1)?
I have Visual Basics 2008 express and I tried to make a autotyper, so this is my
Button1: Timer1.Start
Timer1: Timer2.Start
Timer2: SendKeys.Send(Textbox.text)
Button2: Timer2.Stop
So it was my first try ever with VB and it kind of worked... Only 2 problems;
1. Button 2 doesn't really work, I have to click it really many times, then go to a different window, then click it really many times again, in the meantime it keeps on spamming
2. How do I make my autotyper press enter every single time after the textbox message was typed?
