View 4 RepliesI'm viewing reports on a VB.net form using CrystalReportViewer. Once a report is opened, the Access database that is used within the report is locked (i.e., the Access MDB file can't be deleted). Even after the report is closed, the database stays locked until the VB.net app "ends". This is a problem because I want to be able to delete the MDB file at some point while running the app and can't. The VB.net app starts by opening a form named "Startup". No database connection occurs here. A button is pressed using this [code]I must not be properly closing the CrystalReportViewer or the Report form.How do I close the Crystal report and unlock/release the Access database?

View 21 RepliesHow can I detect when a client disconnects from the TcpListener ?
Each of my clients is handled in a separate thread.
Searched quite a bit and am having trouble finding how to have the server catch the client has disconnected. When the server detects the disconmnect it goes bonkers. Would like to Try and Catch ex so I could gracefully handle it.
View 2 RepliesI'm using the chat program provided in the 101 examples kit, and have modified it a bit to suit an app i'm fooling around with. I have come across a problem...
When the client side crashes, the server side doesnt realize that the connection has been lost. Is there any way for the server to poll its clients table to figure out which streams are still open?

I want to detect when a new usb-device (can be anything) is connected to the computer. I don't need to know what kind of device it is, I just want to know when it is plugged in.
I found this thread: [URL]
I know the solution is in here, but I'm overlooking it I'm afraid. What I want:
USB-device connected > Run function. USB-device disconnected > Run another function.
I posted the message below in the VB6 section of this forum with no success, but as I've now got access to VB2008 via work, I thought I'd try again here. Basically I'd like to be able in code navigate to a folder held on a mobile device like a mobile phone connected to a pc using MS Activesync? It shows up in the drive list within "My Computer" as a system folder, I've vb6 code to detect all the drives including network mapped drives but not the mobile device.Ultimately I'd like to do file copying when my program detects a mobile device has been connected.

Well im trying to make my own basic Slider control just so i can learn abit how to interact with the mouse...
so far i have this:
vb.net:
Private Sub Rectangle_MouseMove(ByVal sender as Object, ByVal e as System.Windows.Input.MouseEventArgs)

To detect rotation of the mouse wheel in .NET/WinForms, I can override OnMouseWheel. Clicking can be detected by overriding OnMouseDown (it's just the Middle button). But how do I detect tilting of the wheel (tilt to the left/right for horizontal scrolling)? Neither OnMouseWheel, not OnMouseDown is being called when I tilt the mouse wheel.

View 3 RepliesHow would I make my VB Program detect mouse clicks? I want the code in a timer. So if I turn the timer on, my program will detect a Mouse click and then do the rest of the Timer code. And after the timer code is done, I want it to do it again until the timer is closed. So if the timer is on, every time I click the mouse, (anywhere on screen) it will do the rest of timer code.
View 2 RepliesI have been tasked with showing a tooltip when I hover over certain TabPages within a tab control, I have tried everything I can think of to resolve this little task, but still I am left with no clear answer.
the events that I would normally use, seem only to fire if the mouse is over the actually tabpage, I am more interested in the tabpage under the mouse in the tabcontrol.
