View 2 RepliesTo .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.

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.
So I have got a program with a timer on, a few labels displaying coordinates, and two buttons. Here is my

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?

View 1 RepliesI'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)

Is it possible to change the aero colour (like instead of the default blueish aero have like a black or yellow one)?
I don't want to change the settings on the computer, just for that application to have a different colour aero colour.
I am making an application which is capable of displaying a picture, and making adjustments to it. Unfortunately i'm stuck at this phase:The colour of each pixel in the image should be inspected and stored in one or more arrays.

I have a dilemma whereby I have a form which contains a number of comboboxes that contain information/options/items that may be invalid/out-of-date in certain circumstances.I can't simply remove the out-of-date information from the items, but I do want to give the user a visual-clue when options are invalid.
View 2 RepliesI 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.

I have created a program that Draw a circle and then you can move it around a picturebox. I have made code so that it changes colour but instead of changing the colour of the circle already been drawn it creates a new circle which when you overlap the original circle with the new circle it cuts part of it.So what I wanted it to do when I change the colour of the circle it changes the colour of the circle already been drawn instead of creating a new circle.

Also I can't use the X and Y coordinate input to move the circle to the entered coordinates.

I am making a html editor in visual basic 2010 for Uni and i am coming across some problems.
I'm using the richTextBox because it is more editable for what i am doing. The first of my questions is: How can I change the colour of text.
What I have done so far is add a timer that will constantly check to see if the user has entered... lets say "<div>" then i want that text to change to a different colour... say red.
My second question is: Obviously in web dev when you write the <div> tag you have other content inside it like: <div id=""/> so how can i make the entire string between the < and the > or the <div> </div> become the same colour.
I need to convert a VB.NET colour to a hex code.Here is my code thus far:
TextBox1.Text = ColorTranslator.ToHtml(Button1.BackColor)
The back color of button 1 is red. However when I use this code the textbox types "red" instead of "#ff0000". Is this because when typing HTML, most normal people would type:
<font color="red">
<!--- Instead of typing --->
<font color="#ff0000">
