The problem is that it raises the event even if the picture didn't change.
comparing the 2 images without actually comparing them pixel by pixel (too slow to do the job)?

I have a lot of keyboard keys stored in different formats. For example, "Up" may be stored as a string, as a decimal (200) or as hex (C8). I need to convert all of this different representations to strings so they can be easily understood by the user, and then back again when I save them.When I capture the key press using the KeyDown event, I can grab the decimal value from KeyEventArgs.KeyCode, which can easily be converted to hex if needed.

I'm running Microsoft Visual Basic 2010 Express on Windows 7, using a Regional Setting set to New Zealand.
When I enter a date in a NZ format (d/mm/yyyy), the IDE highlights the date and tooltip reports date constant not valid. But it is valid for NZ! Meanwhile, the IDE happily accepts dates in the US format.
I would have expected VB to look at my PCs regional settings and set this as the default format. What is wrong here? I have reinstalled the application, but still have the same problem.
I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
View 2 RepliesI would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

View 5 Repliesduring the development of my project, i've fall in the need to change the position of some forms, pixel by pixel using a timer.Now, i've checked that the movement is very fluid when form is not very heavy, when it contains few elements, but when it has a lot of elements inside, the movement becames nervous and not fluid, the movement becomes jerky.

I worked in a role and functioning properly. The problem is that it is a bit slow for use in many images would be very slow. I read online that with stride and scan0 and working in memory with buffer can be made faster, but i donīt understand anything . Does anyone know how it works or how to make my code run faster?

I have been using Bitmap.SetPixel & copying the entire bitmap to a picture box after the entire graphic has been drawn. When running debug within the IDE, this takes less than 10 seconds, while DrawEllipse or Rectangle takes almost 4 minutes.I will be using the more time consuming method for my next application, since that application requires seeing points set in Picture Box as they are generated

I'm loading a picture into a picturebox. How can I set the pixel width to a fixed number, ex 300?
The whole picture must fit the picturebox, even if the original resolution is higher.

bmp.SetResolution(300, 50)
