I've been trying to customise a datagridview but no luck so far, thing is, i want some of the cells to not have the same grid colour and width as all the rest of the grid. Do you guys know how can this be done? I know it is possible cause i've seen it before but i have no clue how to accomplish that.

I am not a new coder, but i am not a know-it-all. I have been watching some of those NVidia fluid videos, and got jealous. I thought "Why can't i do it?" I'm not good enough for OpenGL or some other 3d engine, but i thought i would try it in 2d.

I have a requirement to have a button filled with a gradient colour (red to green) & can't seem to find a way to do this.I am able to draw a rectangle & do a gradient fill, however I need the buttons backcolor property to have the gradient fill rather than a rectangle on top of the button.

I have a DGV with the Alternating row color set to grey.In the CellFormatting event on the DGV I want to go through the rows as if a cell contains a certain value I want to set the BackColor to red.However when I do this, it just gets overridden with the Alternating grey color. The cell in question in a normal colored row appears in red as expected, just not the alternating row.

I 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 have created a custom logonui.exe in VB.NET and I know how to make it replace the existing logonui.exe, but I am having trouble with the functions, such as shutdown, restart and log in. I don't need to get the list of users, because there is only one user account on the system and it is not password protected. I just need it to log in to the account when the user clicks a button and to be able to shutdown when the user clicks a different button.

I am just staring off using VB 2010 after using 2005 for a while. In 2005 I used a third party control to automatically make a button a default color and when the mouse rolled over it, it changed to another color and then back to the original color when the mouse left the button.
I want to be able to set this as a default for all of my buttons in my project as there are tons of buttons throughout. I found the ControlTemplate. I don't know if it is the answer or if I don't understand how it works, but I just am not getting it.

I have a problem with changing the color of a button (in vb.net). I have searched the web and plenty of people are willing to tell me HOW TO change the color but my problem is - it doesn't. I say it doesn't, it does when it has finished the rest of the code in the Sub. Can anyone furnish me with an explanation please as to why it doesn't happen when I ask? I'm using Visual Studio 2008

I have a form with a split panel. In the one split are a group of buttons which I want to programmatically change the color of the last pressed button.The following loop seems to run correctly and set the colors correctly but the form doesn't represent that. Once the loop is completed and I recheck the button colors, they revert to previous state.[code]I can get the desired effect by doing the below code but seems less elegant and would obviously require updates as buttons would be added or removed.[code]

I am trying to create 5 Bitmaps 'on the fly' which I want to use in a ToolStrip DropDown.So far I have found a working way but I wonder if there isn't an easier way to do that?The reason why I have to create this images 'on the fly' is because users can select different colors for the Categories (which I have managed with Button(x).BackColor, so, in order to have the Menu Items shown the exact same colors I try to get a Bitmap based on the Button's back color and add it as MenuItem picture.Here is my code to create the images:
Public Sub MenuCategoryImages()
Dim menuPic1 As Bitmap = New Bitmap(24, 24, PixelFormat.Format1bppIndexed)
Dim pal1 As ColorPalette = menuPic1.Palette

I created 3 Forms (Form1, Form2 and Form3) and I added a button on every form. This is code for Button1 on Form1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.BackColor = Color.Red
Form3.BackColor = Color.Red
Me.Hide()
Form2.Show()
End Sub
Code for Button1 on Form2:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form3.Show()
End Sub
Code for Button1 on Form3:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
Form2.Show()
End Sub
Now, the problem is that when I click on Button1 on Form3 it shows Form2 but the Form2 BackColor is not red, it is default color, A.K.A Control Color. But I specified in Button1 on Form1 that Form2.BackColor is Red. And also if I click on Button1 on Form2 when Form3 shows it, the Form3 BackColor is also default, it is not red.
I know one way to solve it but it is so not-professional. It is that you add on Button1 on Form2 this:
Form3.BackColor = Color.Red
and on Button1 on Form3 this:
Form2.BackColor = Color.Red
It is ok in this situation but what if I have more stuff, for example if I have an option for changing theme so it has to change all labels and buttons ForeColor, what then, is there any other way?
