I have a splash screen on the application and on that form. I have a timer.
Private Sub Splash_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SplashTimer.Start()
' Set application title
' Set Version
[CODE]...
Interval on the timer is set to 5000.
Private Sub SplashTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SplashTimer.Tick
SplashTimer.Stop()
[CODE]...
I set breakpoint here but it doesn't seem to hit this breakpoint. I uncommented Me.Refresh(). Splash screen is closing. Then Login is shown with a continue button. When you click continue button. MainMenu.Show() 'this form should be shown as this is the main window of the application but it's not showing. Me.Close() 'closes login window. No window shows up and the application is hanging.

I have notice that when a module is running the screen does not update properly.For example if I change a label to read "Please Wait..." The second half of the label does not display until the program is idle.Can I get the screen to update while its running.

I wanted to make a screen recorder (not screen capture) program, but I am not entirely sure how to get it started. I have seen many videos and things on how to make one, but all of these just take multiple pictures and then don't compile them into a movie file, and I don't want to take many pictures (unless that is the only way possible.) I am using Visual Basic 2010 Express and I have looked at the Windows Media Encoder, but I can't seem to figure out how to use/implement it (yes, I have downloaded and installed it.) Maybe I can use some kind of ActiveX control?

Sometimes when updating the entire screen or moving around controls etc, there is some fairly bad screen flickering.

I'm trying to run an app (GacUtil) which is normally run through a console window, directly in my winforms app, but I keep getting the error:
"The system cannot find the file specified"
Here is the
Dim AppName = "gacutil"
Dim BaseOptions = " /i"
Dim oStartInfo As New ProcessStartInfo
Dim sFull As String
Dim sStartPath As String = Path.GetDirectoryName(TextBox1.Text)
[Code] .....
In this case, the DLL is in C:, and 'GacUtil' has been added to the Environment path variable.
I can put a break point on the next to the last last line, copy and past the output of the 'sfull' variable into a command prompt and it will run perfectly. (I've tried adding oStartInfo.UseShellExecute=False, removing the whole workingDirectory property line and just changing sFull so that it has the Startpath also, but I still get the error)
However, when I try it in the Winforms app I'm creating, I get the error.
Process.Start(oStartInfo)

I have an application that insert or update Data to an SQL server every 2, 3 hours.I can't use the SQL server itself (creating a new job). Instead I defined a timer which executes the code every 3 hours.The application runs in the server - a winform application.And this is the problem, when I logoff the application is being closed.Is there a way to keep the application running?

When I first saw Silverlight, I thought that there was a How Do I: video that demonstrated how to capture the PC screen and save it in a WMV file. Since I can't find anything like that I'm wondering if I was dreaming or it has been removed from the Net. My goal is to create a video capture Class that I can use to demonstrate my program and add the feature in my program so the user can record any issues they are having with my program and send it to me. This way I can see what issues they are having with my program.

I know that a service in Win7 doesnt have a desktop associated to capture a screen - so normal techniques dont work.But how do i overcome this? How do programs like VNC and alikes do it? My code in WIN XP works fine - but in Win 7 i get black image.

Is there a way to detect screen capture or recording is processing.
Atleast a way to know the process behind screen capturing?
i guess something has to be done with Kernal side of the system but not sure.

how would I allow my screen capture to crop and capture only a particular area of a screen?The user should be able to select the area they want to crop. It would be good if the cursor changers to a plus like other screen captures and also the screen is all paused so the user can select the area they want.v

I have a application (client) that does a screen capture and sends it to another application (server) over tcp/ip.The problem is that sometimes the images recived on the server i corrupt, it only displays a part of the image, like there is data missing.I have tried to set the sendbuffer and recivebuffer to different values, some works better but not good enought.

I'm looking for some help/examples on reading or updating the video capture filter properties in VB.NET. I am working with a USB video device that came on a Panasonic Toughbook. The camera has alot of functions that the user can set when running the software that came with the toughbook (zoom, bightness, contrast, etc)

I have a winform with a main panel that is anchored top, left; dock: fill, and set to a specific size to contain another panel of content that we want to scroll through. The other panel along with a few other controls are on the main panel. Now, for some reason, after running the application the controls will be shifted down (never horizontally) some random amount. Now, the "random amount" may in fact be the last position of the scroll bar or something, but either way, it is unintended functionality. I have resorted to automatically resetting the locations of these controls on the main form in the constructor?

I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it.

I'm trying to develop a windows form app which will take a screen shot every 30 seconds for about 45 minutes. After 45 minutes, the user will click Finish, and these screenshots will be uploaded to a database. I don't want anything that simulates a PrintScreen key press, because I don't want to alter the users clipboard. The second issue is, for users with multiple screens, I'd like to capture the entire screen image, not just from the primary screen. I'm using Visual Basic .NET 2005.

I have some code that takes a screen capture of my monitor. This code seems to work perfectly OK and can take multiple screen captures, apart from when I do a Print Screen using the keyboard or open SnagIT 8, when I then try to run my code again I get an error "A generic error occured in GDI+"
I am at a bit of a loss, I have had a look on the internet, but everything I seem to find appears to be related to web apps. and access permissions. This is a window based application and therefore can not seem to find an answer.Below is the code I am running:

I'm working on a project. I've gotten all the kinks out of my Client/Server tcp chat. But I need to find a way around this problem.
In my chat room, you can have other users view your desktop remotely. But I'm having a problem with this.Does anyone know how I would get a screenshot or possibly video of the desktop and write it to my stream? I can convert it to a string already. and my old method used screenshots written to the disk. I would like to avoid touching the hard drive if possible, so that means extracting the screenshot/video from memory.
