How can i get the image shown on a Directx Window (I mean a app the uses directx 5,8,9...) and then pic the image and transform this picture data in a text? I mean if there is any text or any number writen anywhere inside of it?
View 1 RepliesI have a specific image that I want my application to look for on a specific window. I've done something similar to this along time ago with VB6, but it was slow, and it was checking for specific points in the picture rather than the whole image itself (for speed reasons). I named this image "Image1.jpg" and I want to compare it to the window with the handle "001C08F2" and class "SunAwtCanvas"

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.
View 2 RepliesI am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

View 10 RepliesHow do i center an image at all window sizes? My Window is borderless and maximized so its size obviously differentiates between resolutions. I'm having trouble centering an image directly in the middle of the screen and making it stay there regardless of the size of the window. Docking isn't working neither is anchoring and hoping there is an easier way around this?

View 18 RepliesI'm using VS 2005 and .NET framework 2.0 SP2 to build an application with a datagridview in it. I'm using Microsoft Word 11.0 Object Library to do the spelling checker on one of the field in datagridview. When it detected a spelling and grammar window would pop-up open on top of the datagridview.
The problem I got was when I moved the pop-up window to the new location, there's still an image of the pop-up window left behind the previous location. The more I moved the more of those copied image would be created on screen.
I need the whole window to drag when they click and hold an image box. Is there any way to do this? (Example: They move their cursor onto the image click and hold the mouse down then move their cursor. The whole window then moves with it.)
View 2 RepliesI'm making a photo editor and the size of the image depends on the size of the window, like the Zoom mode in the BackgroundImageLayout property of a form. It works sometimes: when resized only a small amount, it does nothing, but when the image is resized more than that, it jumps to the right position.

usually with C#, though the controls I'm using for this project are VB. Usually I work with programming backend robust applications, but of course when I do a simple website for a friend is when I cant figure out the problem. I'm using a VB master page for the site. The "wood" div is supposed to be a background image that repeats dynamically as far down as the page goes, but for some reason it only goes as far as the browser window height. The background-repeat:repeat-y doesnt seem to do anything, so I feel like the problem has to do with the CSS. Here's the master page:

View 4 RepliesBeen away from coding for almost 10 years, trying to get back into it but am a bit rusty. I have been asked to write a program that will allow users on a network to write hire data, driver data, job calander etc to a SQL database. The program works perfectly at the moment apart from one thing.
The program must allow the users to add an image to a drivers record to have on file, I have read loads of different forums, tutorials etc on how to do this and have managed to get my program to size the image properly and store it as binary data (i think) in the SQL database. I am now having problems doing the reverse and making the program read from the database and display the image in a picture box, the following is my code to save to the database

I have an asp.net repeater. In this repeater I have in each itemtemplate two image buttons.
If I'm clicking on an imagebutton, the other imagebutton in this row changes it's URL. I want that this URL is saved, after clicking on another row's imagebutton. So I'm adding in the repeater event
ItemCommand
Dim imgButton As ImageButton
If e.CommandName = "imgBtn1" Then
imgButton = CType(e.Item.FindControl("imgBtn1"), ImageButton)
imgButton.ImageUrl = "myURL"

While debugging, it still skips everything, because all Attributes are empty (but actually they are not)!
