I was trying to show an waiting icon when processing a time consuming operation (to let user know something is running behind), but no sure what's the good way to do it? for example, i have a picture box holding this animated Gif, and initially i set it to be invisible, but I want to show it and actually working (alive) when clicking a button, this button will trigger a do loop ending after 1min.

What is the best way to keep a thread alive
View 1 RepliesI am working in Visual Basic 2010 and need to check if a port is alive on an ip.I am currently using this code

TextBox2.Text = "Server Online"
Else
TextBox2.Text = "Server Offline"

When using teh system.threading.timer or threading.threadpool. queueuserworkitem, you are able to pass an object.

I have an application that connects to an SQL Server, sometimes we have a networkinterruption of min 10secs during the openconnection , I get a General Network Error when I try to carry out any procedure that communicates with the database afterthe interruption. Even when the connection is closed and reopened, I still get General Network Error. The only way to get the application to function again is to close the Application and reopen it, is there any way I can keep the connection alive?
View 11 RepliesI am trying to make a basic server/client program but I ran in a problem.
[Code]....
When I click connect in the GUI the first state of sock.ctlstate is 6 , connecting then the connected event is triggered and after that the sock.ctlstate is 8 , "Peer is closing the connection". But I dont understand why it does this. I should keep the connection alive to communicate.
if i go to sql server configuration manager and shutdown the SQL server, the server will be down.
How do i detect for those changes using vb.
Public Sub CheckConnection()
Dim con As New SqlConnection
Dim objCmd As New SqlCommand
[Code]....
I cant make those work because the connection opens and close. WHat i want is to check if the server is alive or dead.
I'm trying to setup sort of a LAN keep-alive proxy...Ex.: My Xbox 360 is connected strait to my computer via an ethernet cable. My computer is connected to the internet via a Wi-Fi adapter. Everything works fine and I can access the internet on the Xbox and computer.
Issue: Every time I start my Xbox I have to set up a "Home or Small Office Network" via the control panel to access the internet. What I would like to do is implement a proxy that when I shutdown the Xbox the LAN doesn't give the "Network Cable Unplugged" notification. I wasn't sure if there was a way to make the connection stay open for so long after it should say unplugged. Such as if I need to restart the system and don't want to have to re-setup the network on the computer.
This is my code to retrieve the network info:

Animated GIF in Winforms
View 9 RepliesFirst part of a huge block will contain some text. That block is not always visible. it will be visible when the user is inputing a control. It is drawn in a bitmap image which will later be a part of the final image of the form.The second part consist of several small bitmap images most probably will contain a letter. These images will not change but there position will keep changing by time. These images will be free to move even beneath the huge block (If visible).I used a timer with 1 sec. interval to redraw form, but when the block is visible it keeps flickering because the timer clear the form and redraw the block.
I tried to use different container for the block like the PictureBox but when the small image goes beneath the block it just disappear.The block color code is "Color.FromArgb(100, Color.Black)" I tried lower Alpha components and that didn't make any difference.My explanation is that the background of the picturebox is not transparent. If I'm right how to make the picture box transparent?

I've been racking my brain trying to figure this out. I've done a ton of searching but I can't find what I'm looking for. Right now my program gets a image file, converts the image to 4 colors (Black, Red, Yellow and Green), then converts each pixel to a number for that color.This works great, but now I'm trying to do this for an animated image, but I need to be able to loop through each frame, but I haven't been able to figure out how to access each frame of the image.

I have already created code to extract 10 incremented images from a pretty much any video format. Now that I have my images, I thought the most efficient way to animate them would be through a GIF.
