C# - Taking A PNG Screenshot Of A Window, But Keeping The Aero Transparency?
Jan 21, 2012
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?
My problem is when I develop my own applications in Visual Basic 2008/2010 with the Aero interface, I cannot see the text both on the form and in components. After researching on the internet, I have come to a dead end. Is there a way of fixing
Noticed that in my MDI Application, all my child forms lose the transparency of the border that Aero provides. Is there a way to "force" them to inherit the styling or is there a property i've overlooked to allow this?
My program can detect when Aero is present, but it has trouble when the user is in Aero Basic because it doesn't use the transparency or glass look. I am wondering if there is a call to the dwmapi that can tell me if the computer is using Aero Basic.
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.
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?
I'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
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?
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.
I have been working on an image capturing tool for a long time now & I was wondering how some of those programs are able to make an aero capture of a form.I know you can capture a window if you have it's handle by using the BitBlt, but that doesn't keep the transparancy of the aero form.Let me give you an example:I did a lot of research on google but I never found anything close to something that explains how to do it.
I 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.
Is there a way I can take a screenshot of a window that is not the active window? I want to give the user his current open windows and he select one of them as the target window for the SS, my target is to let him work on one window while my application will take ss of not active window.. what is the best way to accomplish that ?
I'm making some Aero-style transparent forms (signature), and they work just fine. However, to get a screenshot of the area behind the form using Graphics. CopyFromScreen(), the form has to be less than 100% Opacity, so CopyFromScreen doesn't include the window in the picture. This also means that when you have more than one open, they see through each other.
I want to make a screenshot of a specific window of which I know the handle. I know there is a BitBlt function but I can't get that to work with the handle, I prefer it to work even if the window is not active but I'm not sure if this is possible at all.
I'm having trouble getting an naero glass code which works properly. I hav ecome across many in which anything black becomes aero aswell. Is it possible to have the black text unaffected by the aero like, change it so that another colour becomes aero instead?Also this is just an extra but can you change the colour of the aero you have? Like default is blue change you change it to like yellow, or black or another colour?
to be so simple turns out to have me scratching my head.I have a program that monitors input inside of Quickbooks. When a customer is entered into a sales order my program checks my database for any special information and if it exists, opens a TopMost window to the lower third of the screen with the information showing that is special to that customer. The problem I have is that when the customer is found and the window opens, focus is taken away from Quickbooks and given to my newly opened form. Is there a way to prevent this so that the users input isn't interrupted?
With frmMessage .Width = Screen.PrimaryScreen.WorkingArea.Width .TopMost = True
I am developing a game and I want an options window to be used so that the user enters data into this and it carries to the main window instead of being lost. I tried it with my recent program , guess the color , but it did not work the way I thought. I thought that I could assign it to a string in a textbox to a variable and it would carry into the main window...
I want this to happen: The user begins the program by clicking shortcut User clicks options in the toolbar A new window comes onto the screen
In this window the user will select a map size then click ok the verify , radiobuttons used in this example... Back to the main screen after clicking ok User clicks new on toolbar to begin game Game is then playing...
Form1 <<< Form 2 game screen 3x3 button end turn
Form 1 New game is begun form 2 appears 3x3 button is pressed* variable is used to change map (there is only one map for now)* form2 closes and form1 shows End turn is clicked
I'm working on a UNO (Msn-based) online gaming tool - you know the card game. It's the second version with more features for UNO fans. I would like to get the screenshot function to work.
It's just as simple as this: The UNO main window The screenshot viewer shows the screenshot of the active window (which appears by clicking on "Screenshot"): (This form is named as "Screenshot", the Picture Box "myPictureBox")
My question is, which code do I need to bind these functions. I think the pictures are describing this good enough. (The "save screenshot"-button is ToolStripButton1, the button for making screenshot is ToolStripButton10).
