Any 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?
Is there anyway I can do a a custom screen shot? like the height and width of it? This is what I want to do
Left = 18
top = 556
right = 914
bottom = 289
So a regular screenshot on my pc is 1152 by 864. So how would I say do a 300 by 400 screenshot?

View 17 RepliesI 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

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 8 RepliesI trying to figure out how to take a snapshot of the image in a WebBrowser control so I can copy it into a PictureBox. I'm not talking about copying a specific image from within the web page, just taking a snapshot of the overall view visible in the browser window. Unfortunately my knowledge of VB .NET's graphics, image, and bitmap commands is very limited.

View 2 RepliesIs there a method to hide your application from screenshots without the use of ".hide" or minimize or opacity basically not touching the application at all but not including it in the screenshot? For instance in GDI when you g.CopyfromScreen the mouse is not included and you would have to go through a way drawing the mouse onto the graphic can something like this be achieved with application?

View 14 Repliesscreenshot application I am developing that has a memory leak somewhere. The main code is as follows:
Public
Class Form1
Dim strPath As String = "C:windows empscreenshot.jpg"
Private Sub Main()
[code].....
The application runs from the system tray and a clickevent handler for the notifyicon control calls the Main() sub. The code calls OutlookEmail() which creates a new outlook mail object. The problem is that each time the notifyicon in the system tray is clicked the memory in use jumps up incrementally - about 3mb each time.

Is there a way to use ReadAllLines to read in a text file that contains some Chr(10) (linefeeds) but uses ONLY the Chr(13) (carriage return) as the true end-of-line?What I mean is, DON'T treat a Chr(10) as the EOL. ONLY treat a Chr(13) as the EOL.Obviously I could just read in the whole file as binary and then split it into lines by scanning for Chr(13), but I just wondered whether or not there's a setting in VB.NET to set the EOL character so I didn't have to do that.

I have wrote a program that uses sendmessage to automate clicks. I have also made it where it can minimize to tray, hides form & shows an icon in tray. The problem is that when it's minimized it takes focus from whatever else I'm doing, like if I'm typing in Notepad when the program sends the message it takes the focus from notepad.
View 2 RepliesWe have 2 apps that we display at once for data entry. 1 taking up the left side of the screen, and 1 taking up the right side.
1 of those apps is the data entry application. The other app is for viewing scanned info. But they can't talk to each other directly.
So I'm creating a tool that runs in the background to intercept certain keys.
I want to be able to capture keys such of Ctrl + Home, Ctrl + Page Up, etc from the data entry application, and send it to the scanned image to rotate it or zoom, etc.
I believe I can do most of it, except 1 part.
Right now if I did Ctrl + PageUp, it will send the key press to both apps. How do I prevent a keypress from the originating application?

I am trying to simulate human temperature taking. Basic i just need a button, a text box , a progress bar and a timer.What I want to do is that when the button is clicked, the progress bar will slowly increment and after it reaches maximum, a random number in the range 35-40 will be generated in the text box.Now so far, this is what I`ve done:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Start()
Dim r As New Random
[code]....
So the progress bar is working fine. The random number generator too. But here are my problems:
1-Once the button is click, the number is generated. I would like that to happen after the progress bar reaches maximum.
2-So this is suppose to be a temperature gadget for kids and therefore when a certain amount of temperature is reached...an alarm is sent to the parents. How do I generate a dialog box (to acknowledge an alarm was sent) in case the temperature exceeds say 38? The dialog box should close after some 5 seconds. If possible, in case of such excess, the button color should turn to red or otherwise(no excess) blue.
I am working on a program where the user inputs values, then the program calculates those values and outputs the sum. When the user hits the button exit then those values entered by the user are saved. When the user starts the program again, the values are still there. I wrote the code and everything works fine. I am saving those values in notepad... and the program grabs the input in notepad and outputs those values to the program. But here comes the problem: Lets say the user wants the information in a certain column to be added to another column somewhere in the program. Is that possible ? And if it is can it be done when I am saving those values in notepad?

I have the need to either prevent, or restrict, the termination of a VB.Net application. I have no problem with Admin killing the application, but not a user. I've been unable to come up with a solution for this. Is there maybe even a way to set local policy to prevent termination by non-admin?
