I'm using VB 2005.

When I select a color from the properties window for a control, it returns
an RGB color code (255,255,255). Now, when I attempt to assign a color in
code it is done using the COLOR.COLOROPTION value. How can I take an RGB
color set in the properties window and assign it via code. For example, I
have a control who's color is (192,255,192). I want to be able to also assign
this exact same color via code using the ControlName.BackColor property. I
tried doing ControlName.BackColor = RGB(192,255,192), but I get a message
stating "Value of Type Integer cannot be converted to System.Drawing.Color".

How can I assign an RGB Color to a BackColor via code?

Thanks.

I don't know "COLOROPTION". Where is it declared?

ControlName.BackColor = Color.FromArgb(192,255,192)

I guess you wanna just make your program to fit different themes
automatically.

I have a stupid way to deal with that.
First, build a dictinary(of SomeRGBValue, COLOROPTION) by your code, using
enumeration e.g.
And you can get the COLOROPTION while you want to.

Hi Greg,

Armin has provided the correct solution to you. Control.BackColor property
expects an object of type "System.Drawing.Color". You may use
Color.FromArgb() method to convert numeric RGB values to the
System.Drawing.Color object.

Note: the "RGB()" function you used in the VB2005 is a legacy VB function,
which convert the RGB values into an integer value, instead of the
System.Drawing.Color type object. So the VB2005 compiler will emit the
error message: "Value of Type Integer cannot be converted to
System.Drawing.Color". See the reference below:

Thanks.

Best regards,
