I need to convert a VB.NET colour to a hex code.Here is my code thus far:
TextBox1.Text = ColorTranslator.ToHtml(Button1.BackColor)
The back color of button 1 is red. However when I use this code the textbox types "red" instead of "#ff0000". Is this because when typing HTML, most normal people would type:
<font color="red">
<!--- Instead of typing --->
<font color="#ff0000">
when i click a button i want to get the fore colour(text colour) of a label on the form, then use this colour as a brush
View 4 RepliesIs there any way to change the colour (background colour or text colour) of just a certain item or item(s)?
View 2 RepliesI've been searching for quite a long time how to do this. I don't know how to set the colour of a row item in the GridView (WPF) using code I don't want an example in XAML. My data comes from me loading & pulling apart an XML file. I then put it into a small class with properties and those are bound to the column to populate the data. Later, it can begin some functions on the table's data. Because this takes at some times over 10 minutes it's on a thread & I would like to colour the rows I've completed parsing depending on the result. (IE: Red for HTTP error, Orange for XML parsing error ect...)This is the GridView's XAML:[code].....
I am then parsing the data using the url column. I am currently changing the selected item as I go through. I want to know if theres something I can do to change the specific item. Let's assume I'm on row 500: I use: setSelected(i) which uses Dispatcher to safely change the selected row. Is there anything I can do to change the colour as well?
To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim BMP As New Drawing.Bitmap(1, 1)
Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)

To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.
I've got a combobox which loads the system colour list, the selected colour is stored in the registry (i've tried storing the index number value aswell as the colour name - how can i get the combobox to display the stored colour as the default colour when the form loads?

How can I format the colour of a datagridview by code.I know I can do this:

View 1 RepliesI'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)". Is there some method in the Image, Bitmap or Graphics classes I can use, or will I simply have to inspect each pixel in the image with GetPixel, check whether it is a white pixel, and then set it with SetPixel?Here is the code I am using now:
Private Shared Sub highlight(ByVal b As Bitmap)
Dim highlightColour As Color = Color.FromKnownColor(KnownColor.MenuHighlight)

I found some code on the net that is supposed to convert a BMP file into a AVI file.

I have some code, that I am converting from C# to VB, in the code is the following line.
int index = ((int)document.GetCharAt(wordOffset +1)) % 256
that translates to something like this:
Dim index as Integer = CInt(document.GetCharAt(wordOffset + 1)) Mod 256
The problem is that the GetCharAt() function returns a Char type (pretty obvious from the name). VB throws an error saying that Type Char can't be converted to Type Integer. So my question is, what is the result of the explicit conversion in C# code?
