VS 2008 Change Form Opacity Without Changing Control Opactiy
Mar 16, 2011
I need to be able to change my form's opacity without changing the opacity of the components.
I really only need to do this on one form in my entire app, so this is getting a little frustrating
I've been researching for about half an hour now, trying to figure out if it's possible, but I'm coming up short.
I've seen some WPF examples and if it really comes to that, I'm more than willing to change the app from a WinForms app to a WPF app. I've made a WPF app before, so I'm familiar with it. But, I don't want to have to remake my entire project for this one form.
On that note, does anyone know if I can make a WPF form how I need it and just import it into a WinForm app? It doesn't seem possible, but it's better to ask than not. I'll look into this more.

When I set the opacity of a form to 50%, the opacity of a label on that form is also set to 50%, but I do not want so, is there anyway to make a 100%-opacity-label with 50%-opacity-LabelBackground on a 50%-opacity-form?

I want to make it so when someone places the mouse cursor inside the form the opacity is 100% but when it leaves then it drops to 75%. This is my code:
Private Sub Form1_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.MouseEnter
Me.Opacity = 100%
End Sub
Private Sub Form1_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.MouseLeave
Me.Opacity = 75%
End Sub
The forms default value is 75% and it works fine when I mouse over. However when the mouse leaves the opacity doesn't drop. What am I doing wrong?

I have a form with a PNG image as its background image. How can I make the form's opacity match the opacity at different parts of the image? (for example, I have a drop shadow that fades from black to transparent. How do I acheive this effect on a form?)

I have a form which has a user control in it added dynamically. How can I change the values in that dynamically generated user control? All my functions are in a module and I will just call them in main form. So in module how can I find that user control and change its values? I tried writing a function in user control form. Like it has 10 txt box and I tried to pass a structure as argument in that user control form but I am unable to do so. when I tried to declare the structure outside function parameter in user control form it works well but not as function parameter..

I can't find a way to change the opacity of a mdi form within it's parent. I can change the parent form's opacity under properties, but can't change the embedded mdi form's opacity under it's properties. Opacity = 0.5 doesn't change the opacity of the mdi... works fine for the parent form. I was hoping that the embedded mdi forms functions would still be independent of the parent in order for me to change it's opacity.

I have my form set up to be able to be kept on top if the user so chooses. When it is set to be kept on top, I want the opacity to be reduced when the form loses focus. When I set opacity on init, it works fine. When I use this code, it doesn't work:
Private Sub Form1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.LostFocus
Me.Opacity = 0.2
End Sub
[code]....
Maybe I misunderstand how LostFocus and GotFocus work, but according to MSDN this appeared to be what I wanted.

setting the form opacity programatically in the MouseEnter and MouseLeave events.The problem isn't with the actual events, the problem is that the events occur in places where I don't want it to happen.So in my project, I have a form with 3 user controls in it. The user controls are docked in the form so no actual space from the form is available to the user.
I have the methods:
Form1_MouseEnter(~) Handles Form1.MouseEnter, UserControl1.MouseEnter, UserControl2.MouseEnter, UserControl3.MouseEnter
Form1_MouseLeave(~) Handles Form1.MouseLeave, UserControl1.MouseLeave, UserControl2.MouseLeave, UserControl3.MouseLeave
when you enter the form, the form opacity is set to 1. And when left, the form opacity is set to 0.7 .However, what happens right now is obviously that when the user changes the mouse position from one user control to another, the form opacity flickers (turns to 0.7 and back to 1 really fast).

I've got a richtextbox control on a form and a menustripitem that allows me to change the font style. What I want to be able to do is to allow the user to type text into the richtextbox control; then if they change the font style using the menu only for newly entered text to change font, and any previously typed text to stay in the previously selected font. The problem I'm getting is that all of the entered text's font style is changed.

I have created a custom user control. I place it on a form, and want to have it fade out to totally invisible in response to an event. I'm assuming I need a timer to adjust the opacity some how, but there does not seem to be an obvious opacity property of a user control, unlike a form. I can't use a form, so I have to get the control to do this somehow.

I'm trying to change the look of some controls in VB.An example would be a button, I now have a stack of 4 images on top of eachother. By using the mouseover events and such, I get the same result as a normal button. However, I'd like to be able to insert those images into a normal button like thing.
I know it's possible to do this by creating a custom control, but that'd end up with the exact same code, just in a different file.
However, the real issue would be a dropdown box and slidebar. I'd like to get them to look nice with my theme. (Background, buttons, borders. Things like that..). I got absolutely no clue on how I should do that.
I know that there's a tool to create controls, but that's from scratch and I can't get a grip on it, at all.

I searched around google for a couple of hours to see if I could find anything on what I wanted to do.
Needless to say, I didn't find much. Basically, what I want to do is, when my main form loads, I want to load another form that sticks to the desktop but is transparent (Opacity) except for the text I want in it.
The only thing I could find is how to reduce the opacity of the form. I don't want the form to have a border or be able to be moved around by the user. I still want the user to be able to put icons over it, but not mess with it. I also don't want it to show up on the task bar. Kind of like a background in it's own right.
I'm not even sure if a form is what I need to do this. I imagine that it can be done.
*Edit: I found an example of what I want, but I'm going to fill my form with different info [URl]..
