I've got a chart showing data as a part of a vb.net forms application. The Chart object makes a really pretty picture, but I need it to match the color scheme on the rest of the UI. How do I get the RGB values for the palette?

Is it possible to see the different colors (when using the graphics class) in a palette somewhere? It's hard to choose from the names only (DarkCyan, IndianRed ect, what is this!? )
View 7 RepliesI have a array of pixels. And I would like to Quantize them.
For Example
FF00FF,00FFFF stuff like that, but most are custom colors and are not a standard 256 color palette. So I need code to convert a color to a 256 color. I dont have any idea on how to do this, but thats why I came here. I do not want to use System.Graphics.Image.Palette or anything like that as this project uses arrays for images. I would like to if at all possible be able to convert a R, G, B color to 8bit, 16bit, 256bit and possibly use the HSL or NeuQuant method or something close to that, or maybe even some other methods of doing it. I do need to be able to do this for a single pixel, but I will also need a method for a array of them.
i would like to have an image like this one on my form.e form to turn this color
View 2 RepliesI have a DataGridView which populates from an SQL query just fine in default mode
using these table names
[firstName] [varchar](20) NOT NULL,
[lastName] [varchar](20) NOT NULL,
[code]....
I have edited the column headers and set the column names to the same values as my table names yet the data is not showing in form load I have set datagridview.AutoGenerateColumns = False I know the data is there if I delete datagridview.AutoGenerateColumns = False then the data is shown with the default headings?
I'm trying to find the colors of pixels using GetPixel(x,y) with bitmaps.
I understand how to use it and it works.
When I use .ToString I get the string version of the color.
Now when I use .ToArgb I get a negative number and the colors are backwards?
16777215 should be white and 0 should be black.
This is an example of some results:
-16273900 is showing close to black and -32567 is showing close to white.
I can get the custom colours used in the ColorDialog (vb.net) by using yColorDialog.CustomColors, which will return me an array of colours as integer values

I am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:

In the above example:
MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18

View 4 RepliesI'm working on a little project that will inpart take the registry values for the exchange server configuration on a windows mobile device and then convert them to an OMA provisioning XML file. I have the xml code nailed, but we discovered in that process that the active sync exchange partner subkey is named differently on every device but, obviously the value names stay the same.
This is what I have so far but I'm stuck on obtaining the key name and then placing it into variable.
Const branch As String = "SoftwareMicrosoftActiveSyncPartners"
Dim ActiveServer As RegistryKey = Registry.CurrentUser.OpenSubKey(branch)
Dim subkeys() As String = ActiveServer.GetSubKeyNames
For Each subkey In subkeys
'some actions
if name "Server" exists then
Dim exchkey =
Else
messagebox.show "Exchange Server not configured. Please configure a server and try again"
Basically I have a form with Five textboxes and what I want to do is to click a 'Submit' button and copy not only the text from all 5 textboxes but the name of the textbox or a label.
Sample:
Names / TextBoxes
Box1: Text1
Box2: Text2
Box3: Text3
Box4: Text4
Box5: Text5
And when you click submit you would get the text in that format when you paste it in a separate textbox.Is it possible and how would I go about doing that? I know I can copy multiple textboxes but I want to retain the label or title along with the filled in text.

View 14 RepliesI would like to add the names of people in a SQL Database to a Multiline textbox if two values in their row do not equal 6. The first name and last name, as well as graduating year need to be added to the textbox, and then a new line needs to be created. The two values are contained in two separate columns in the DB. I'd like to try and stay away from using SQL Queries to accomplish this, so is there any way I can call these values using VB? Keep in mind the number of people that have values under 6 may vary from time to time. The purpose of this will be so that someone can print out a list of members who don't have the required amount of points at any given time.
