I have an image in a picturebox that changes, and the background of the image is ls always the same. is there a way I can change the background of the image? Here is the picture, or at least one of them.
The white background behind the character is what I need to remove. How can I replace certain colors of pixels with another color?
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.
I need to take the image and clip a sliver in the middle and repeat it to make it like the second attachment. (so its 320px wide)i dont need to save the result... I need to cut it in half... then use drawimg to draw the left half, then the center "slice" then the left half.
View 4 RepliesIn 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.

I would want the program to check the top right hand of the screen in the exact coordinates and see if the pixels match. if so return a variable true.

View 4 RepliesI'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.

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.

how to remove a line?I have:
Dim PenColor As New Pen(Color.Black) and after I received the values I draw the line with:
objGraphics.DrawLine(PenColor, Xstart, Ystart, Xend, Yend)
The user can do this 10 times... (so 10 lines)...But if the user presses a cancel button, the last line drawn shall be removed (and the user can click until he is back at 0)..Would I use PenColor white here (to draw over the line)? Or is there a way to remove line directly in visual basic? I couldn't find it.

View 6 RepliesI'm saving potentially very large amounts of data to disk as a single serialized class. But there is a sub class that I would like to be able to retrieve and write back to the disk without having to read the entire file or write back the entire file. Trust me, my reasons for doing this are good, and the design behind this is more than correct.In VB6 this is very easily done. A single statement gets the portion of the data you want from the front of the file and saves it straight to the Type it belongs to, flawlessly. Likewise, if the dimensions of the data haven't changed, but only the values, then Put can be used to save it right back to the file without disturbing the integrity of the entire file.When needed, the entire file is read into a larger structure, and the entire file is put back, but only when necessary. Most of the time the only information being read from and written to the file are in the first few hundred kilobytes of the file.
Now that I've got serialization working, I'm trying to use it to read (deserialize) only the first member of the class serialized to disk. I haven't been able to find any examples of this anywhere that have lead me toward making the sort of progress I'm hoping for.So I suppose the first question is this: Is it possible to read only part of a serialized class from the open file stream? Specifically, in one case I want to read the first two integers stored in the class. In another case I want to read only the first block (sub class) from the open file stream. In both cases I do not want to read the entire file, but just what I'm interested in starting from block 0. I don't need to write back the integers to the first file, but I do need to write back the block to the second.Assuming that the answer to the above is yes. My second question would then be: How is this done? I want to work with the file stream already open rather than opening and closing file streams over and over.I

The received file (in my test case it is a PNG file) comes through corrupted - I'm 99.99% sure its a case of encoding but I've tried various options and in each case when I open the original file and the received file in notepad the files are visibly of the same origin but some characters are wrong in the received file. I'm sure its a simple answer but I can't find it - what am I doing wrong in terms of re-assembling the received file?
