I'm trying to take a screenshot of my screen, and get the picture from memory. Then convert it to a string so it can be sent over a network. So far I've tried to adapt this code.
Dim
ScreenSize As
Size = New
[code].....
I'm using the code below to get a screenshot of the entire screen.
VB.NET
Dim b As New Bitmap(Me.Width, _
Me.Height, _
[Code]....
But I need to edit it so that it only takes the a screenshot of my form. I'm not sure how to pass the absolute coordinates of my form's top most left corner and it's bottom most right corner.
I know how to take a screenshot, but how can I take a screenshot of the screen behind my form without hiding the form, taking the screenshot, then showing the form again?The reason I can't simply hide the form to capture the screen behind it is that I need to take the screenshot repeatedly, and hiding the form each time I need to take the screenshot would cause the form to flicker.
Here is the code I'm using now:
Me.Opacity = 0 ' Hides the form. Can't use this!
Dim bounds As Rectangle = Me.Bounds
Dim screenshot As New Bitmap(bounds.Width, bounds.Height, Imaging.PixelFormat.Format32bppArgb)
Dim g As Graphics = Graphics.FromImage(screenshot)
[code]....
I am looking to create simple application that means that when the 'Print Screen' button is pressed, the screenshot is not just sent to the clipboard but saved to the desktop in either JPEG or PNG format.The application will run at startup so that the 'new' print screen functionality is there but the interface of the app is opened manually.(the app interface includes simple options such as choose where file is saved.)
View 4 RepliesI picked vb.net for this question since it's the only prgramming language I am fairly familair with, but if C++ or something else is more suited for this, I am willing to learn something new.What I am trying to do is:Retrieve text from database (this already works in vb.net) and copy it to clipboard Switch primary screen to the external application I want to work with (example: word or open office) Emulate key-press "Enter" Paste text and hit enter again Emulate key-press CTRL and then emulate a click on a pre-defined spot on the screen (like 500pixels from left, 740pixels from top). Save screenshot, using a second value from the database as the filename (the naming part should be easy) Emulate another click on another pre-defined spot Repeat for next text in database.I wouldn't know where to start, though. I guess the most important part of what I'm trying to achieve is; switching focus to an external application and emulate keypresses and mouse clicks on it.

So I'm trying to take a screen capture of the windows form and display only a certain specified area of that screen capture in a picturebox on a different form. Kind of like this. First, take the screen capture of the form: Then get a specified area of that form through x,y coordinates or something and display it on a picturebox on a separate form.
BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

I'd like some direction in taking a screenshot of just a specific area. The area I need is where the rectangle encapsulates. If 've played around with it for a while tyring to figure out how to just take a screenshot of the rectangular area, but can't seem to figure it out.
I wrote some code for a program I am making to take a screenshot when the program is minimized. Thing is something is wrong with the code and I am not sure what it is. Whenever I take a screenshot the program is taking the picture with the application up and not minimized.
So what I need it to do is minimize the application then take the screenshot and then reopen the program after its taken the screenshot. for the noob question but I am brand new to the VB and only been coding it in for less then a day.

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.
