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 am drawing five images in a row. The five are the same thing at five different zoom levels. Therefore, only one of the five will be displayed at any one time, but the others have to be there because there can be over 100 images being displayed on the screen at any one time, and each drawing is quite complicated. If I were to draw them all on the fly, then zooming would require that all 115 images be recreated and redrawn with each zoom. That's painful. To avoid that, I draw all five zoom levels of each image. When the user iteracts with the form, they will be interacting with, at most, two of the images, so when they interact with the form, only two of the 115 have to be redrawn, though those two have to have all five zoom levels drawn, for a total of 10 images.
Ok what's happening is I'm pulling in a Tiff file that can have multiple pages. I selected the first frame, draw a stamp image to it and save it as a different file name.When I do this, it is only saving the first page of the tiff file. How do I get all of the pages to save?
I require a "Indicator Control" i.e. I need to display a "multi coloured indicator" with each colour representing a certain condition. Basically "I want to build" a multi colored LED on a Form. I have used a Radio Button before but I need more than 2 colors and the Radio Button is a very poor choice.
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'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? It always defaults to the first item in the colour list I've tried
So I have got a program with a timer on, a few labels displaying coordinates, and two buttons. Here is my
[code]...
It displays the color of the pixel at the coordinate typed into the text boxes.I have a video of a tennis ball which is bouncing on the spot, and the background in brown, so when the tennis ball comes into view there is a significant color change and i want it to start and stop a timer each time the colour changes significantly.So my question is, how do i get it to check whether the colour chas changed significantly?
Ok, i've been making my own syntax highlighter for my project, and i need to know how to make the colour of the text between these two text values green
My VB2010 programme changes the background colour of a button (butExtra.BackColor = Color.Red). But how do I restore the colour to the default "Control" colour?
i am looking to change the windows colour and colour intensity. These settings are accessable through Control PanelAppearance and PersonalizationPersonalizationWindow Color and Appearance But is there a way that i can remotely change these two settings through functions in my windows form application? Also is there any way of removing the slight blur on the window bars/taskbar when using an aero theme?
I am currently working on a piece of code that allows the user to change the colour of some text in a text box. I have done the size and fonts fine but colour i am struggling on. I am using radio boxes to select the option. The code I used so far that works is this but how do I add the colour into it?
Private Sub radioArial_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles radioArial.CheckedChanged If radioArial.Checked = True Then[code]....
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
Well, i created a form and added a textbox and a button to it, when i press that button this text "VB Forums" appears in the textbox. The question is, how can i make that those initial letters (VB) appear in another colour e.g Red but the remained Text (Forums) stay as it is.
that is my code.. my problem is in my richtextbox1, there are many line that contain "Not Found". So how can i change colour for all of that text to red colour? my code only work only with a single line that contain "Not Found".
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
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)
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 would like to know what code snippet I would use to keep the RTB text colour the same as the chosen foreground colour,Currently any text colour that I ,say for instance C&P into the box is black (apart from when I manually type in the RTB).
Ok so i have a form of witch the user is able to change the background image of. The form has labels on it. How can i make the fore colour change to be if possible the opposite colour to the image where the label is in order to make it readable?
I'm making a custom control that needs to look like a Text Box but I can't Inherit Directly from text box since I need to add, Change and Override so many things that it would be more practical to just inherit Control and start new.
But now my question is: Is there an easy way to create the basic functionality of a Text Box like drawing the Text Box and handling input ?
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 want to sort the above column inorder that, all the line contain Twst will come first then blue, red and finaly black. This is my code so far
Sub coloursort() Dim lines() As String = File.ReadAllLines(TextBox1.Text) For Y As Integer = 0 To lines.GetUpperBound(0)
[code]....
But the above code replace the line with 1,2,3,4 or 5. According to select case statement. How to modify the above code so that it sort the lines?
I'm looking to see if a little more control is possible though. cpustring = string and fontstring = font, both defined earlier in the program.I'm not sure how to clear the drawn text before drawing a new text. I tried with g.clear(color.transparent), but that creates an ugly flickering background for the picturebox (the picturebox is already set to transparent background).I'd also like to be able to fit the text in the picturebox area, max width/height as defined by picturebox, not by fontsize. Font can stretch either way as long as it fills in the picturebox.
