View 3 RepliesKnow how to use the track bar to control the brightness or darkness of an image in a picture box,use track bar to sharpen an image and to use trackbar to emboss an image.
View 6 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.
I am making a program with pictures in its resources... I want to build in a viewer that zooms in and out and I can view every part of the picture.

View 7 Repliesknow the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse?I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects.I've had a look in reflector but it's one of those controls where most of the implementation is not viewable.
ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this?

I'm using Microsoft Visual Basic 2010 Express and I've been trying to make an application, a word processor, which has it's own custom tabs, I'm not making a new control, instead using a trackbar and adding richtextboxes to a panel for add tab and removing them for remove tab. and when the user changes the value of the trackbar, the richtextboxes too get changed by using the bringtofront property of the richtextbox with the index that is the same as the trackbar value. basically, as you drag the trackbar, the rtbs should get changed here is the code: the following is for a timer that keeps updating the number of rtbs, etc. [Code]

View 1 Repliesi am currently devloping a set of fully GDI written controls, just 4 fun and to improve my GDI skills Anyway, my problem is as simple as that i don't get a trackbar to show the correct value when i scroll it..Heres a picture of my form:As you can se, i got a box on each side of the trackbar which is currently showing 1 and 10. To calculate the value i first have to multiply the current location of the trackbutton with 100 and dividy it with the width of the trackline and then dividy it width the maximum value - the minimum value, right? But i just can't get it to work, i am only 15 years old and math is just not my strongest side.. yet..W1 and W2 is the size of the boxes + the space between them and the trackline.
Dim W As Integer = Width
Dim W1 As Integer = S1.Width + 10
Dim W2 As Integer = S2.Width + 10
