i am creating an rtf editor and i am trying to Change the colour of selected text. at the moment my code changes the colour of the whole text, but i want to be able to highlight my text and have 2 seperate colours, below is my code. Have tried to add .selectedText in but it says it 'SelectedText' is not a member of 'System.Windows.Forms.ColorDialog'.
ColorDialog1.Color = Editor.ForeColor
If ColorDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
Editor.ForeColor = ColorDialog1.Color
End If

First I am using 'Microsoft Visual Studio 2010' and am making a 'windoms forms application'. I am wishing to implement a way of changing the text colour through out the whole application. I have managed to put on a customisable background using

I know I'll have to change the 'BackColor' bit but I don't know what to. Is there something that turns all text on the form one colour or do I have to do it label by label?
Also I am can't figure out how to rotate labels to display text at a 60 degree angle (to display along the edge of an equilateral triangle) And for the triangle I have drawn it using lines which move independently from each other, is there anyway to 'group' these lines together so they are fixed.
Is there any way to change the default colour to the highlight when a listview row is selected? Apparently the default blue colour causes some problems for some users who have some visual eyesight problems. They didn't tell me what colour they wanted but they did indicated the blue is annoying.

I have a button (btnAdd) that adds the content of a textbox (txtName) to a textblock (lblName). I want to add a date to the textblock when btnAdd is pressed but I want it to be a different font size and colour. So far my code looks like
lblName.Text = txtName.Text " " + DateTime.Now
I only want DateTime.Now to be a different size and colour. Is this possible? Instead of a label I need to display it in a listBox. My new code:
listBox1.Items.Add(txtName.Text " " + DateTime.Now)
I'm looking for a way to change the font colour on alternate rows within a datagrid. e.g. normal row would be green and the alternate row would be blue. I can change either by using
me.datagrid.Styles.Row.Forcolour
me.datagrid.Styles.AlternatingRow.Forcolour
The problem is that I am having trouble using both of them together as I need to manipulate both colours. I have created a HtmlRowPrepared event and have been setting them there, however, If I set the Row.Forcolour first, it will over ride the AlternatingRow.Forcolour and vice versa. This needs to be done via SEVER SIDE code only as the colour choices are held in the database.
I am currently working on a VB.NET project and the hardest thing that I am having trouble with is that everything is black and blue. Having worked a lot with C#, I really like the way that types are colored differently.
I have tried going in and having a look at the "Tools > Options > Fonts and Colors" and the various "User Types" under "Display Items" is set to a different colour but its not reflecting that colour in the text editor.
I am making a diary Form in VB.NET to do this I am using a listview with two columns.
Column 1 consists of a list of time and column 2 is the description
Can I change the colour of certain cells in column 2 only. So when I read in the data from the database it reads in the description and then puts the data in the relevant time slot but I want the recent cells of the description column to be a different colour.
Is there any way to change the colour (background colour or text colour) of just a certain item or item(s)?

How exactly would you go around doing this?

From the properties pane of VB.net, I can only change the whole TextBox's font colour.
I have been experimenting with my windows form application(vb 2008/10) and made sure that the top part(glass part) extended to become a bit larger.Now 1 problem occurs. Everything, like text, which is black, will become transparent so unreadable. With labels and pictures, I solved the problem, I just write a string(e.graphics.drawstring) and for labels / titles I use a long method(not important). But now the problem comes

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 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?

I'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)".

I have a large number of textboxes on a form that are set to read-only until the user clicks an Unlock button. I have left the default colouring in place (no code required), so the boxes are light grey when read-only and change to white when not read-only. The problem I have is that Windows Vista's colours are so insipid and pale that it's hard to spot the difference on some monitors. It all looks good on an XP desktop but the difference is too subtle on a Vista PC.
Can the default colouring of a read-only textbox be changed? I know I can change it in code with backcolor but I don't want to put loads of code behind my Unlock button. That's the way I did it in VB6 and I want to get away from that. I just want to use the default "greying out" action when making the texbox read-only, but change to a slightly darker grey.
How do I add text to a TextBox instead of changing the textbox as a whole. Also, how would I make a newline when adding to the textbox?

does anybody know of any good Visual studio 2008 books to help me with code. I used to dabble in QBASIC and finding the changover quite difficult.
I'm developing a program at the moment and I'm trying to add the capability to add a texbox everytime you click a button. This is simple other than I'm trying to be efficiant as possible, so I made a sub that creates the textbox and the button calls the sub. Here is where it gets tricky I want the new textbox to move just below the previouse textbox, I'm not sure how to do this since Im only really createing one textbox over and over and having a variable name it by one. This souds confusing I know, but check out my code and it will make since. Really all I'm trying to do is change the location of a unknown textbox say since I create a textbox name textbox0 then when I hit the button again my varibale goes up by 1 which makes the new textbox, textbox1. how to I tell VB to change textbox1's location....
