And is it even possible to do a vb6 style implementation? As I see it, this will clone the picture image while the vb6 implementation will just read directly off the image? and is lockbits like getdibits? I need to process 60 bitmap images of about 200pix by 200pix every second.

View 3 RepliesAs a side project, I'm trying to see how much of Microsoft's Paint Application I can recreate. So far I have it where I can "paste" the image into the application. What I am stuck on however is allowed the image to be edited - being able to edit the individual pixels. How can I "edit" the pixels inside this picturebox? - Jordan If you find an answer , click the button. If you find an answer to your question, mark it as the answer.

I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.

Now to my questions: How can I zoom into certain X, Y positions on the map? After I zoom into the map, how can I call a function when I highlight a tile(pixel), and then another function when I click on a certain tile(pixel)?
I am trying to make a picturebox follow another picturebox. But I also want this picturebox to be able to collide with the other picturebox if the picturbox stops. I hope this is not too confusing.

PictureBox1.Location = New Point(PictureBox2.Location.X)
PictureBox1.Location = New Point(PictureBox2.Location.Y)

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

I'm trying to make a picture box do a "fade in" effect. I just don't exactly know how to code it. The general premise is, in the main form's load event handler, I'd run a procedure so that when the form opens up, a picture will fade in. I have 20 copies of the same picture, each gradually less and less faded.I was thinking of cycling through an array of all the images with a timer control so it animates and fades in.
