Progressbar query

[PhilBayley]

My apologies if this is simple to solve but I am having problems with the forecolor of my progress bar. I want it to be blue but it just wont change. I have positioned my progress bar onto my statusbar and it works fine but it just wont go blue. Can anyone see whats wrong.

 

this code is in the forms contructor

 

Thanks

 

Phil

 

InitializeComponent();

 

progressBar2 = new System.Windows.Forms.ProgressBar();

progressBar2.Parent = statusBar1;

progressBar2.ForeColor = Color.Blue;

progressBar2.Left = 3;

progressBar2.Top = 3;

progressBar2.Width = 260;

progressBar2.Height = 18;

You can't just reference the color.blue directly, you can if you imported system.drawing

 

Otherwise it would be system.drawing.color.blue.

Yep I did import the system.drawing stuff and Ive also tried it your way but with no luck it still remains grey.

Are you 100% sure that it is enabled?

Even though these color properties are there, you can't use them like this. The control doesn't do anything with these properties.

 

Personally I think that the progressbar is the worst control in .NET. It seems to be missing several key features (like displaying text/% overlaying the progress bar, a 'smooth' progress bar option, and being able to change the colors as you've just discovered.

 

I hope they fix this soon!

Ummm - Im not sure. I know that it is in place where it should be and when I change the value property from another function, the progressbar increments as it should. The only thing it wont do is change colour. :-)

here's the link to an example i made a long time ago in c# for colouring a progressbar ... colouring a progressbar in C#

it allows you to colour the back and front :)

How does this work? And why can't we do this in VB.NET?

[dynamic_sysop]

we can do this in vb.net :) if i get time between feeding duties i'll knock you up an example.

ok i translated it over roughly, here ya go...
