this line of the code makes the form see-through "User32Wrappers.SetLayeredWindowAttributes(Me.Handle, 0, _
255 * 0.4, User32Wrappers.LWA.Alpha)"
if i adjust 0.4 to 0.6 it will become less see-through.
i would like to know if i can control this variable through a trackbar and how!

create a form with a TrackBar control so that when you Scroll the TrackBar it generates a frequency based on the value of the TrackBar. Beep() isn't really what I'm after. I was wanting it to smoothly transition through the frequencies. Basically, I want to create something that sounds something like a Theremin.
I've been looking online, and I can't seem to find anything. I don't even know how this would be accomplished. Is there a simple command to say "play this frequency until I tell you otherwise", or do I need to generate a .wav on the fly and have the system play that?
know 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?
Is it possible to add a trackbar control to a StatusBar (not StatusStrip) control?Goldfish64

View 6 RepliesI'm looking to draw a trackbar normal, only with a transparent background. I have created a new class that supports transparent backgrounds set to true. Without using userpaint, the trackbar does nothing or takes the color of it's parent. When using userpaint I have to draw the control on mine own. Not quite sure where to start first though...
I've read about drawing a line (not so hard), drawing a floating object (to act as marker), and handling events on when the floating object moves left/right... Drawing 3 separate objects inside an inherited trackbar control seems like a clunky way of calling methods that should exist somewhere? Is there an easier way to draw the control normal without a background? If not, some in starting to implement all 3 new objects working together would be good (I could draw them separately but that's about it).
MainForm having a few buttons, VolForm is inheriting MainForm. I can see this perfectly in the designer.VolForm itself contains a trackbar. Now have 2 forms. Form1 and Form2 both inherit VolForm. If I change the trackbar from Form1, and then show Form2, the trackbar is not having the same value. Is there any way to keep this trackbar the same in every form that inherits VolForm?

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
