I'm trying to make a program that kinda works like Windows 7 when you put you're mouse over a program in the taskbar, and it pops up a small realtime screenshot of the running program while its minimized.Anyone know how I can go about doing this? I took a small code from the internet, but I always a error "Generic Error occurred in GDI+".[code]
View 2 RepliesI have a picturebox. I want to at certain points take a screenshot of whatever is in that picturebox and write it to a bitmap variable.The images in the box will be of varying sizes and i will be tracking the sizes using image.height and image.width. I would like to use those to define the area for my screenshot.

Finally "upgraded" to vbnet and got no idea how to do this! What I'm doing is using bitblt to take a screenshot of the desktop and put it in a picturebox. What I really need is just the raw data from the picture, not the picture showing on a picturebox.
Only problem is that it is not working at all!
Here is the entire sourcecode. How is it not working??
Module1
Module Module1
Public Declare Function GetDesktopWindow Lib "user32" () As Long
Public Declare Function BitBlt Lib "gdi32" (ByVal hDCDest As Long, _

I am making a program to automatically take and save screen shots and I am using the F12 button. It works fine, but the problem I have is when I press F12, it will take and input the picture into the PictureBox1, but if I try to clear it, and then do it a second time, it wont work a second time. My clear button code is:
Picturebox1.dispose()
here is some of the code that i have:
Public Function CaptureImage(ByVal X As Integer, ByVal Y As Integer, ByVal Width As Integer, ByVal Height As Integer) As Bitmap
Dim JPEG As New Bitmap(Width, Height)
Dim G As Graphics = Graphics.FromImage(JPEG)[code]....
when the timer hits a 2 second interval the picturebox on form 3 gets a new image from the screen shot that form 4 takes off of form4's area. i want the user to select a folder with the "folder browser dialog" and i want each frame capture to be saved to the folder (every 2 seconds) that the user chooses as "1.jpg, 2.jpg, 3.jpg" etc .
I knew everything I needed to save an image, so I type in my code, and yet another error pops up. Here's the bit of code:
screenshot.Save(CaptureMain.picLocation.ToString, Imaging.ImageFormat.Bmp, "Screenshot")
And, the error's kind of lengthly...
Error1Overload resolution failed because no accessible 'Save' can be called with these arguments:
'Public Sub Save(stream As System.IO.Stream, encoder As System.Drawing.Imaging.ImageCodecInfo, encoderParams As System.Drawing.Imaging.EncoderParameters)': Value of type 'String' cannot be converted to 'System.IO.Stream'.

The variable 'screenshot' is a bitmap.
