I'm developing a device app in VB.net that will access a SQL Server database. I need to establish a connection when the app is launched, and keep the connection open until the app is closed. I've done the following:In the Master Module:
Public CNN
As SqlConnection
In the Main menu form load:
CNN =
New SqlConnection(sqlConnString)
CNN.Open()
Then when I want to read from the database:
Dim sqlDR
As SqlDataReader
SQL = "SELECT Name FROM Table"
[code]....
When I run the same code without the global CNN, but rather dim the connection inside the Select function, all works well.

View 5 RepliesHow to change the database connection by using openfiledilog in windows forms? The application I need to do, need to connect to a database, each time with different path and different name to explore the opened database. All the databases to be accessed are having the same structure, but with different location (in the pc itself), different name, and with different data inside (but the database tables and relations are the same.

View 3 RepliesAfter deploying and installing my application I use the app to create and save a file with my own file extension. After the file is created I right-click on the file and select Open With.. so that I can associate this file extension with my application. In the Open With dialog I use the Browse button to find my application and select it. In the Open With dialog the application icon is shown, but the name of the app is blank (looks like an empty string). Can anyone tell me why this might be happening? I've looked at the Registry, which shows the correct app, but every time I open the Open With dialog only the application icon is displayed, no name.
View 2 RepliesI'm developing a WinForms app in VB.NET, that handles sets of style data, and when the user clicks on another set's label, it prompts through a dialog "You are leaving this style preset to edit another one. keep changes on this one? [Yes] [No]".But, I'm facing the problem that, when the user clicks either option, and the dialog closes, everything has to be refreshed, and loading the form again seems a good option.[code]But as soon as that sub is called from the prompt, it crashes the application. (doesn't show an error in debug, simply crashes) How should I, from a given dialog, close the dialog, it's parent, and re-open it's parent? (which triggers all the Dialog_Load() code of the parent)

I have some code that loops in the background of a form and triggers action if the form is active (this is in a mdi forms application). I use the following to check this:
vb.net
Dim frmActive As Form
frmActive = Me.MdiParent.ActiveMdiChild
If frmActive.Name = Me.Name Then
'Do work
End if
The problem comes when that form starts another form running in dialog mode i.e. form.showdialog. I need the above code not to run while this is the case, but it still returns true when the dialog form is active and the other form is in the background.
Is there any way to detect whether a dialog is open in an mdi environment?
At one point I have a dialog form open, but in order to process it, the user might want to access information on other (open) forms. This would necessitate the ability to move/resize/scroll the other forms, but obviously everything is frozen during the dialog. I don't suppose it's possible to achieve this "semi-modal" state, where other forms can be browsed, but no other actions taken?
