View 3 RepliesI am trying to verify that an image has been loaded into the picturebox1. I am loading the image from the web and need to verify it has arrived before I can save it to disk. If I save it to soon I will save nothing and that will crash the app. I have tried to use 'if PictureBox1.image = nothing then' ... 'End If', but that isn't a valid check. I can obviously not check picturebox1.image if it is empty or has an image.
So the question is, how do I verify that the file has finished loading?

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?

View 1 RepliesI have a picture box in a panel control. I want to be able to scroll the image in the picture box. I have added two separate scroll bar controls (Vertical and Horizontal). When the control loads, it load the image properly. However when i scroll the scroll bars, the image vibrates but does not actually scroll. Is there a property I need to set in the picturebox? I am assuming that when the picturebox loads the image that it defaults to Normal. Thus the image is clipped. Does this mean that I cannot scroll it? I have tried the other SizeMode properties (Stretch, AutoSize, Zoom etc). But I still cannot get the image to scroll.

I have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.
I want to rotate an image by x number of degrees.

I am creating an application where when I click on an image I need to mark the place using the x and y co-ordinates given by the click and then after marking I put a red dot/circle on that spot and then I need to save this image to a file including the dot/circle I marked. I have tried saving the image to the file but to no avail, I have been able to only save the PictureBox image and that doesn't include the graphics. It is only the base image. I have tried to save it as a bitmap but have not gotten anywhere with that either. It seems whenever I call the image.save it takes only the value of the underlying image and saves it.
