View 3 RepliesI have used CSV files before for a simple database of about 12,000 items - this was a simple one page form... Now I want to have the same database but with the data available to multiple forms at the same time.. eg.. Form 1 displaying persons 1,2,3,5,7 name, addy, phone etc and form 2 pulling info for persons 2,3,4,8... Is this possible with CSV files?? or even XML?...

View 3 RepliesHow can I make a form with a new webbrowser control on it every time?
View 13 RepliesI have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer)
Dim sw As New Stopwatch
sw.Start()
Do While sw.ElapsedMilliseconds < interval
' Allows UI to remain responsive
Application.DoEvents()
Loop
sw.Stop()
End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.
I'm developing a big VB.Net Winforms application. Every now and again, processing or db connections take some time and therefore I'd like a wait cursor (hourglass) to appear sometimes. I know I can do it like in this thread (in case someone needs the code):Hourglass?- technical discussion - developer Fusion - ASP.NET, C# Programming, VB.NET, .NET Framework, Java and Visual Basic Tutorials However, I have LOTS of code and I don't know when the user will need to wait. So, what I'd really want is to tell my ApplicationEvents file or the like to globally intercept after say 0.3 seconds and turn the arrow (default cursor) into the hourglass and at the same time disable mouse clicks and the like.
