.NET - Check If An Image Can Be Deleted Or Is Writable After Using It To Perform .net Image Scaling
May 4, 2011I've got an app where the user uploads an image and the app resizes the image three different ways based on different variables. They all use the same image. I can't check to see if it's done using the image so I wondered if there was a way to check to see if the file is writable. A small loop that exits once it becomes writable (or "deleteable"). Working out of VB.NET.

Oct 18, 2010Basically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?

May 16, 2012I am trying to code something that will check if a png image is visible on your screen. So lets say the image is a purple square with yellow circles in it (random example). It will keep checking to see if the same purple square with yellow circles is on your screen. What I'm trying to say is, instead of checking for one pixel color, check to see if the actual image is on there (maybe multiple pixels?)

Interface And Graphics :: Check For All Colors In An Image Without Sweeping Through All Pixels?
Apr 26, 2011I'd like to check for all colors in an image. I've already came up with this:
Code:

Dim img As Bitmap = System.Drawing.Bitmap.FromFile("C:image.jpg")
For x = 0 To img.Width - 1
[code]....
Unfortunately this needs to sweep through all the pixels, and it's EXTREMELY slow... method to get all colors in an image without sweeping through all pixels?

Oct 11, 2011I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:

VS 2008 - VB BITBLT Equivlant - Build Image By Opening Files With Image Data
Nov 2, 2010In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?
