Icon To Bitmap Removes Transparency
Oct 23, 2009I have a system icon (for example a folder icon) and I want to display it in a richtextbox. That's not a problem, but the transparency of the icon is gone and is replaced by a blue color. I tried to use the MakeTranparent function of the bitmap object, but with no luck. How can I make the bitmap transparent again?
Here is my code:

View 7 RepliesC# - WinForms TrackBar Control In .Net?
Apr 7, 2010know 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?

Custom Tabcontrol Using A Trackbar
Jan 21, 2011I'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]

Apr 16, 2011i 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
