I would like to have a picture box, that contains something.. This then can be zoomed in on.. Moved around.. ect. What's the best, most effective way of doing this?
View 3 RepliesSo I've got a picture box and I want to load up all kinds of pictures programmatically , with unknown dimensions. So I pick sizemode Zoom to ensure that the image isn't distorted and I can see all the image. However if the image width is greater than height it vertically centres the image in the PictureBox control's bounds, leaving a gap at the top and bottom.
What I'd like is for the picture to be alighned to the top of the control in this scenario. So the picture will be immediately below a control above it.
Is there any way of acheiving this? Perhaps by over-riding paint event ?
Oh PS: The Picture box is docked to 'fill', otherwise I'd just change it's dimensions in code to have the same aspect ratio as the image.

View 5 RepliesI'm using VS2010 and I've set up a form with a picturebox inside a panel and have zoom working via the mousewheel. The user can also pan by clicking and dragging the mouse. So all good so far. But I've struck a problem.
When I zoom it is anchored on the top left of the image.
What I would like to be able to do is have the user click a point and zoom on that point, or at worst a simple zoom on the center of what is displayed in the picture box.

View 1 RepliesUsing a webbrowser within VB.net (VS2005) to do some educational exercises and would like to implement some basic functions in the prog rather than jscript if possible.I want to zoom in on a clicked document element. Without going into all the details, I am just getting the ID of the element and splitting it into a string command typ and a number argument arg. Then zoom and scroll as these test lines:[code]This works but only in stages. When I first click the element it zooms but doesn't scroll. If I click it again it then scrolls as expected. I would assume this is something to do with the redrawing of the document being incomplete when I attempted to do the scrolltop but it isn't going through the DocumentCompleted event after the zoom, so not sure how to get round the problem.
