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.
Currently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.
Sometimes when updating the entire screen or moving around controls etc, there is some fairly bad screen flickering.
View 2 RepliesI'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.

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)

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.
View 1 RepliesI have a user who wants to print the form that is on the screen(the entire form not just the data) on the click of a button, is there a quick and easy way to capture it and print it. Kind of like a screen shot? I suggested that they could just do alt/printscreen and capture the form that way and print it but they want it all to be done from a print button for them.
View 14 RepliesI have resized the form by using the following code. what i want to do is that i want to fit the entire screen horizontally...so that the horizontal scroll bar doesent appear.....
Private Sub Resize_Form()
Dim cControl As Control
Dim i_i As Integer[code]..........
Which value do i change in the code that the screen squeezes horizontally ...? There are only two controls on the right side when we scroll....i think if the resolution is done correctly then it will fit in the screen.....but i dont know what chages should be made in the code.
I have a program and wish to generalise its appearance at startup on different machines. This worked OK until I moved it onto a Windows 7 unit with a 22" screen. The front page covers less than 2/3 of the screen. I know I've asked the system for 'working area' but could not find a reference to the entire screen which other applications seem able to use. How can I catch up with them? The code is from VB in VS2005. Is this my limitation?

View 4 Replieshow I would be able to print the entire portion of the screen which the form occupies,Basically, my problem lies in that the way I print now will properly print the form's buttons/labels/textboxes etc. But it will not print the WebComponent AxChartspace that I have added to it. So basically my form is partially blank.

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?
