View 2 RepliesI know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
BUT, it doesn't show the current color.
They all have 0 0 0 rgb.
Why isn't this working? The color dialog comes up, but when you choose a color and click 'OK', nothing changes.
Code:
Private Sub ColorBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ColorBtn.Click
Dim NewColor As New Color

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?

View 3 RepliesI have a small project that requires me to have a font dialog, a color dialog and a print dialog. It has four text boxes that are formatted based on the font from the dialog and the color from the other dialog. I am to print it all out with the same font and color. I have easily put the font in the right place and have the rest of the print set up, but the DrawString wants Brushes.<color> for it's color. How do I make it the same color as in the text boxes? I am not trying to get you to do my HW for me, but everything I see online is the brushes or shapes... if you could suggest something to look into that would be great, but I doubt my grade would be much affected by my printing everything with Brushes.Black like everyone else in the world seems to be doing...

View 3 RepliesI am extracting color codes from css files using regex and would like to convert them into colours. A few examples of colour codes:
#000;
#669933;
#fff
This is my Regex pattern:
VB.NET
Dim HTMLColor As String = Regex.Match(Input, "#[wd]+?(?=[;
])").Value
To convert the colour I am using:
VB.NET
System.Drawing.ColorTranslator.FromHtml(HTMLColor)
This will throw an exception if the HTMLColor is not a valid "html colour". Because some css colors are not escaped with a ";" I have relaxed my regex a little meaning that it can yield #div as a result for example. I just wondered if there is a way to verify the HTML Colour code before the conversion, without having to use a Try..
With my recent new project with HTML/Markup generator/editor, I have run into a roadblock. Basically here is my code for replacing markup with HTML. The way this works is that the webbrowser has the same text as RTB1. Since the Webbrowser supports HTML, it automatically converts to the style that is specified in RTB1. [Code]
View 4 RepliesI have a dialog that is displayed concurrently with the main form and it has a datagridview showing a list of x,y values. The user can actively change the DGV in the dialog, but if I reference the DGV from the main form, it will not capture the user changes, but report the original values that were in the cells. I'm sure there is some sort of refresh or update event I am missing, but I have tried all the VS suggested options for the DGV and the dialog that seem relevant with no luck.
