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)

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.

I have a website in which I have many categories, many sub-categories within each one and many products within each of those. Since the URLs are very user-unfriendly (they contain a GUID!!!), I would like to use a method which I think is called URL Masking. For example instead of going to catalogue.aspx?ItemID=12343435323434243534, they would go to notpads.htm. This would display the same as going to catalogue.aspx?temID=12343435323434243534 would display, somehow.
I know I could do this by creating a file for each category / sub-category (individual products cannot be accessed individually as it is a wholesale site - customers cannot purchase directly from the site). This would be a lot of work as the server would have to update each relevant file whenever a category / sub-category / product visibility changes, or a description changes, a name changes... you get the idea...I have tried using server-side includes but that doesn't like it when a .aspx file is specified in an html file.
I have also tried using an iframe set to 100% width / height and absolutely positioned left 0 and top 0. This works quite well, but I know there are reasons you should not use this method such as some search engines not coping with it well. I also notice that the title of the "parent" page (notepads.htm) is not the title set in the iframe (logically this is correct - but another issue I need to solve if I go ahead and use this method).

I have my form connected to an access database. Two of my fields for example are Date of birth and money. In the access database the DOB field is set to a data type of date/time(shortdate) and the money field is set to currency.When I run my app if i type 5/23/09 into the DOB field it'll auto update the textbox in the form to 5/23/2009 (which is great). If I type 200.4 into the money field it wont add a $ sign or update to two decimals but it will save as $200.40 in the DB. How do I make the money field auto update like the DOB field to format to currency right away?

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.

I'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)
Dim whiteARGB As Long = Color.White.ToArgb

I am trying to make the application similar to Notepad++. Notepad++ colours text depending on what type they are, eg. HTML, PHP, CSS, Java, ect.
I just wondered if somebody might be able to help with this? I have no clue where to start, but I have an idea of how it would happen.
- Text is entered into the RTB (RichTextBox)
- The text is read by the program as it's entered
- The text is coloured depending on the type

I am trying to draw some multi colour text onto a form using the paint event and the GDI+ object (note it has to be done using the GDI as i will be needing to scale and do bmp pixel manipulation on the resulting graphic . I have so far managed to create a class and collection winch allow the user to move the text around and change the displayed string, font and colour.
My question is how can i change my class so that it draws multi colour text? and if possible allow the user (uinsg the mouse to graphically select parts of the text.

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

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

I am overlaying a staff members ID number over their photo using drawstring.
As the image can vary from dark to light no one text colour can assure that the text will be readable.
Is there an easy way to invert the text colour pixel by pixel based on the colour of the image pixel the text will be drawn onto.

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)
