VS 2008 : Search For Part Of An Image?

May 14, 2012

I want to be able to:

1) save the screen as an image

2) use this image and search for a smaller image inside of it (pixel sequence)

Basically, I need the program to detect when an image comes onto the screen.NOT a pixel color at a certain coordinate, it is similar to this but instead of one pixel, it should detect multiple ones.is there any way I can put the image I want to detect in a picturebox, and it will go look at that image and keep checking to see if it exists on the screen?I have it working for pixel detection (only 1 pixel), but it isn't very reliable as there could be many other instances of this color on the screen.

[2008] Get Part Of Background Image Covered By ListView Control?

Mar 10, 2008

In my project, I have a form with a background pic that I like, but unfortunately, I also have a ListView on that form which covers most of the picture. Now, is there a way to find the part of the background image concealed by the ListView, and then display it as a background image of the ListView at decreased opacity? You know, like a vague image.Just one more thing, setting the form's transparency key to the background color of the ListView is not an option.

VS 2008 Search A Bitmap For A Similar Image

Jun 24, 2010

I am attempting to create a class library that can either search a bitmap to determine whether or not it contains an exact match to a second bitmap or if it contains a partial match. Currently it only returns true if i search the image for itself or if the sensitivity is below around 15%, even when i search with an image that i know should return true. The images I am using are simply a screenshot saved in paint and a section of that first screenshot also saved in paint. Here is my current .dll coding for VB 2008 Express

ArrayList Search For PART Of String?

Jun 10, 2010

I have an ArrayList, and i wish to search it for a specific part of a string. Like the InStr() function.I can only find the WHOLE string. The ArrayList has strings like "This=Is A String", so if i do a check with ArrayList.Contains. It will only search for the whole string, and not something IN the string. Perhaps i need something like Starts With .

Code:
dim wordArr as New ArrayList
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If wordArr.Contains(TextBox1.Text) Then

VS 2010 Trimming Part Of An Image

Oct 24, 2010

I've got an unusual request. I have an image that will always have bounds that are of Base 2 (2, 4, 8, 16, 32, 64,...) in both dimensions. I need to know if there's a way that I can get a small 16 x 16 square (or smaller, still of base 2) portion of the image. I'm planning on overlaying a grid on this image that way the user can select a portion of it and then the program creates a dynamic image from the selected grid square to use. Is this possible to do? I did a quick search on the Image class and didn't see anything that stood out. Note: This is for framework 2.0, but not picky about jumping to 4.0 if necessary.

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

Multi Form / Part Application Need To Make Part Protable For Transfer

Feb 22, 2011

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts

1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers

2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly

3. the config files

anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.
