I'm taking a screenshot as a System.Drawing.Bitmap and trying to send it through a network as a byte array.If I take the original screenshot and simply save it to disk, it's about 200Kb.Instead I'm saving it to a memorystream so I can write that back to a Byte Array and it's coming out over 6Mb.

View 1 RepliesI', working on a program where there are several projects within a solution. The solution contains a forms application, a couple of class libraries, and a public interface.I'm running into a strange problem where I can access the system.drawing.bitmap namespace from the main form and from one of the class libraries, but when I try to access it from the other class library or the interface, it tells me it is not defined. I've tried importing it, and calling it directly with no luck.
View 4 RepliesI have a VB.NET Windows Forms app with a logo image on the form as a System.Drawing.Bitmap inside a PictureBox.I used the Visual Studio Designer to add the logo .bmp image so I don't currently have any VB code doing anything with it.I'd like to make the current logo a clickable object/button so when I click on it a file browser dialog opens and I can select a new image to replace the current image.The current image is a local resource and is set in a PictureBox as a System.Drawing.Bitmap.How would I replace that System.Drawing.Bitmap with a file selected from the file browser dialog?

I need to capture a screen image of a region in my form. So to say it easily me.captureimage.region (X,Y,Width,hight). I need only to take a screen-shot of the region on my form. So i can set the X adn Y and Width , hight to for example my button. so it has to take an image of my button.
View 17 RepliesAny way to prevent my application from taking screen shot. I am using this method
If Clipboard.ContainsImage = True Then Clipboard.Clear()
If this is correct? And also what about screen capture application they take the screen shot without using clipboard what is logic behind it and if there is any way to resolve it?
I stumbled upon an excellent article about taking screenshots of specific windows in .NET, and doing something with black and white color rectangles behind those windows in order to preserve the aero effect when saving a screenshot to a PNG.Well, I can't find that article anymore, mainly because crap sites and other stuff not at all associated with taking screenshots SEO'd their way into Google's results.Does anyone know how I can take a screenshot of a specific window while preserving the aero effect?
View 1 RepliesI'm working on a program which will allow users to take screenshots of full screen games, such as Call of Duty, Battlefield 3, etc. However, I'm having two issues with my code. First off, I'm having to press the shortcut twice, instead of once like my other shortcuts. This only occurs when the code below is actually in the handling sub. If I just have a messagebox show when the shortcut is pressed, it works every time. Second, whenever I take a screenshot, it either comes out completely black, or takes a shot of my desktop, even though there is a game running in the foreground. I have looked around, and it seems that printscreen is the only way to get a screenshot of a game through vb.net.
My code is below.
Private Sub game_Press(ByVal s As Object, ByVal e As Shortcut.HotKeyEventArgs) Handles gamewindow.press
Dim gamewin As RECT
If GetWindowRect(GetForegroundWindow, gamewin) Then
Dim bmp As Bitmap

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:
