Way To Capture Screen Image And Then Read Data (OCR?) From Image

Feb 13, 2010

I play a game and in the game you acquire skills which you can display on the screen in a box very similar to a data grid. The grid has 3 columns and X number of rows.Column 1 is the name of the skill, column 2 has a descriptive term like "Beginner" and column has the number of points you have acquired in that skill. So it would look something like this:[code]Remember that it is in a data grid so it has cells like an Excel spreed sheet.The program that I use is able to parse the skill name and the points and save that information outside the game to a n area in the program.My question is, is this possible to do something similar in VB? That is something like, Press a hot key, with will get a screen shot, parse the data and save to a data grid in my VB program.

How To Capture Image From Webcam

May 1, 2012

I need to show video in a picturebox, and when a button is pressed, capture the frame. I am making a desktop qr reader. I have the qr reader completed and working. my issue is my camera now. I would prefer something that actually works, and doesn't have severe memory leak issues, and doesn't throw an exception after it's first or second use. Would AviCap32 or Direct Show be better for what I want? Which would capture the image fastest, without causing exceptions? I tried using an open source solution called webcam_capture.dll, and it worked at first, but now I am getting an exception that I dont know how to fix. I'm assuming this goes in vbGeneral, and not the Interop and Upgrade. Most examples I have seen, use interop, so I wasn't sure. I would prefer not to use WIA. I have attempted it, and it doesn't work quite right on my computer, and this application will be distributed.

AviCap Image Capture Without Preview?

Jan 2, 2011

I'm attempting to grab an image from a webcam without having to connect a driver to a window. I'm predominately using code from a devx tutorial. On page two of the tutorial, it shows how to grab a frame using WM_CAP_EDIT_COPY. The only problem is, I don't want a preview window. I want to simply grab the image without having to associate a window handle to a PictureBox for previewing.

Capture Image Of Webbrowser Control?

Sep 15, 2011

I want to capture the image of my webbrowser, or actually just a part of it.I already achieved it, but it just takes a screenshot of it instead of capturing the bitmap itself. So when i use this technique and you drag another window above it, the window is also captured. (this is what I don't want.)

My code:

' 1. Get the WebBrowsers bitmap.

Dim bmp As New Bitmap(WebBrowser1.Width, WebBrowser1.Height)
Dim BMPEndResult As Bitmap
Dim graph As Graphics = Graphics.FromImage(bmp)

[code]....

So I need to get the image of the webbrowser:

- without the scrollbars if possible

- Even if the window is minimized or in the task bar

- Full webbrowser

- and also if possible just a part of it, where I can specify the top, left, width and height

Webcam Image Capture Using Avicap.dll

May 20, 2009

I'm trying to capture an image from my webcam and save it as a .bmp file. the code i have works perfectly except for 1 issue i cant figure out no matter what I try the issue is that when i save the bitmap it only saves in 320x240 resolution even though I have set the resolution to 640x480 everywhere I could think of.

here is the (edited) code I currently have. some places I didn't know what to change so I put in 640,480 anyways to see what happened but that didnt make any difference and also didnt cause any errors so i left the changes there.

Const WM_CAP As Short = &H400S
Const WM_CAP_DRIVER_CONNECT As Integer = WM_CAP + 10
Const WM_CAP_DRIVER_DISCONNECT As Integer = WM_CAP + 11
Const WM_CAP_EDIT_COPY As Integer = WM_CAP + 30
