Changing Colour And Size Of Certain String In Text Block?

Mar 9, 2012

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:

Changing Label Colour - Rotating And Grouping

Jan 24, 2011

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

CODE:

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.

Changing Font Colour On Alternate Rows In GridView

Aug 16, 2011

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.

Visual Studio 2008 - Changing Colour Of Types For .net In VS?

Apr 29, 2009

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.

Colour Picker Scanning - Log On Method - Users Selecting A Colour From A Paint Panel

Mar 15, 2012

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)
GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _

[CODE]...

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.

Colour Changes In Text And Label Masking

Apr 7, 2012

I am making a Hangman Game.

1. How do I change the colour of the text I am entering. i.e. if the letter entered by the user IS in the word, then I want to make that text appear green in the other textbox, "guessed letters"

2. I also want to know how to mask and unmask certain characters at will. i.e. when the user guesses a letter, the program checks to see if the character is in the predefined word. If it is, then I want it to unmask that letter on the label, "Word Label". I also want the program to start with the word already masked.

3. How do I take a random word from a text file for the user to guess?. I have a text file with all the words of the dictionary on a new line.

Here's the mediafire link to my project: [URL]. (The dictionary text file is included)
