converting a string to color. i use the colordialog to the user can pick a color, which is then saved into a db. when i load the color to fill a lable it comes as a string. so, how do i convert:Color [A=255, R=128, G=128, B=255] to coloralso, when i use the colordialog, it will save basic colors as color[TheColor] and complex as the one above. to be uniform, is there a way to have the colordialog always return a hex value? or do i need to write a function for that?
How can i use the color dialogue to return the color selected as a string? So if i was to select red i would like the return to be "Red" and so on so fourth.Another thing i would like to ask is if it is possible to return the color selected as a string in hex color code form (like what is used in HTML for example #FFFFFF, #000000 and so on so fourth).I have a feeling though that it can only be returned as R G B integers but maybe there is a way of converting these to hex color codes?

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin dec2oct dec2hex bin2dec oct2dec hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.
I'm trying to convert a chosen color into hex base 6 to save to a config file for later use, and that part works, but when converting back to integer to use for a color, it gives me an error about incorrect base.
Dim hex_color = System.Drawing.ColorTranslator.ToOle(ColorDialog1.Color).ToString("X6") Dim color_int As Integer = Convert.ToInt32(hex_color, 6) Panel1.BackColor = System.Drawing.ColorTranslator.FromOle(color_int)

How can I change font color of a string. I set the fore color properties of the label holding the string but seems that only works when the string is displayed in that label. Is there a way of setting the color of a string itself such that it displays any where with that color by default. I am actually sending this string as email but wanted to format it in a way that it will display differently however it doesn't.
Well I've been working on a web designer and I wanted to be able to color different keywords and strings enclosed in quotes. Now I've been able to color the keywords but every time I try to color a string in quotes it colors the from the beginning of the document to the end of the quoted string. I've tried looking at samples and apply those methods to the code but it still colors all the text in front of the quoted string as well.This is the sub I'm using to color the text.
