Detecting Color Change?
Dec 19, 2009I want to be able to isolate an area of my desktop (similar to a screen capture snip) and evaluate if it is changing. In this particalr case it is an appliacation I have (not mine) that flashes an icon upon completion
What I want to do is make a small app that will detect change when I am away and perhaps perform a specific action (the action is not relevant really - i can take care of that) Again,this is NOT hugely important, but if someone has an idea or has seen an app that does this, it would be useful for me...
I put this in the VB.NET forum because I write 75% of my code in VB.... so I chose this instead of a general area !!

View 1 RepliesVS 2010 Windows API For Detecting A Mouse Click Anywhere Or On A Specific Program
Jan 4, 2011I need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.

Jun 14, 2010I have a combobox in a toolbar on my form. I want each item to have a specific forecolor. The forecolor property for the combobox only sets the forecolor for all items in the combobox.

VS 2010 Click On A Specific Color
Jan 11, 2012I'm currently programming a program with a webbrowser which need to get the position of a specific color when it appears on the webbrowser. It appears every hour. What I have read so far is that I need somehow to capture the screen of the webbrowser and locate the color from the captured bitmap, but I don't know anything about capturing or positions of colors in images. [code]x and y is the location of the color, FFCC66 is the color program is searching for, the last 4 numbers is where the program is searching for the color like between x: 1 y: 1 and x: 405 and y: 371.

Jan 11, 2012I'm currently programming a program that should automatically click on a box when it pops up in the form I've made.

View 1 RepliesChanging The Color Or A Specific String In A Textbox?
Apr 29, 2009I have a project im working on and im trying to change the font color of a specific string basically how vb does while your coding. (eg if i type dim it turns blue).I want to do this with a textbox in a vb application to show a topic of interest. It needs to be dynamic so when a user types it only changes the color of the specified string. I have tried
If TextBox2.Text.Contains("dim") Then
TextBox2.ForeColor = Color.Red
End If
but this changes all the text in the textbox to the color.
Example Diffrent Color For A Specific Value In A Datagridviewcombobox Column
Dec 23, 2010I wanted to visualize to the user the diffrence if they opted for certain values. In mycase certain choises would show phonenumbers on intranet.To show how I wil leave the control names default. To recreate the the project. Start a windows form application, place a datagridview, and 2 bindingsources on the form To start we need some data to show and a list to choose from.To make a simple example I chosen to make a person class containing an Id, Name and Position.Id If the Position is a staff position it should be blue others should remain the default style.But lets start with the colorScheme Interface so we can store the colorscheme we want to show for a certain positionitem in the datagrdview It wil need back and forecolors but also colors for teh item whilst selected. To show the Displaymember we want to see I've also added the toString property that should shadow the toString of the object.[code]

VS 2008 Scan The Screen For A Specific Color?
Aug 20, 2009A way to scan to whole screen, and find a specific color on it - and after that move the mouse over the color.
This is what i would like the process like, so you guys can have a better idea:
1. A timer that scans the whole screen after a specific color every 5 seconds.
2. When the color appear on the screen, it'll move the mouse to the x, y.
3. After that I'll run some code (i'll hopefully find out of that myself)
I actually don't care how the color should be found. If it's a RGB it will be 255, 209, 102 it should look after. Or maybe it could scan the screen after a matching bitmap. And it's not just 1 pixel I want to find the color of, it's the whole screen I'll like to have scanned for the color, and if the color is found - the program should react.

View 1 RepliesRed Color Of One Image To The Alpha Value Of The Second?
Jun 30, 2009I am trying to create a function that would take 2 images. 1 of the images is a grayscale image and the other is a normal image. What i want to do is apply any of the R or G or B of the grayscale image (in grayscale image r=g=b so it makes no difference) to the Alpha of the second image. i DID succeed on it. However the code is EXTREMELY slow. It takes 1 second to perform it. And i have to perform the function atleast 30 times a second (it will be outputting to a Decklink card). Here is the code:
public function createOverlay(ByVal Main as Bitmap, ByVal Key as Bitmap) as Bitmap
For index as integer =0 To (Key.Width*Key.Height)-1
Dim crntX= index Mod(Key.Width)
[code].....
This function will have to run infinitley until the user presses stop and keep updating the output buffer. How can i make it faster? ( i need at least 30 executions per second)
16 Color Bitmap Image And Interpert?
Apr 2, 2010I need to read a bitmap generated with paint or similar programs and interpert the picture to detect straight lines of black, larger squares in red and smaller squares of yellow, green or red. Which one of the Visual Basic environments are is best suited for this? WPF or Forms or..The lines represent walls and for start we have square objects as obsticles. I would like to create a maze and allow a dot to travel between obstacles leaving a trace of pixels and not hit any of the objects untill it exits.
I like to write the logic for it but I do not know how would I read a 500x500 pixel picture and decode the colors of each pixel. I like to assign a byte for each pixel's color (256color) but only use 4 bits of it to for start.
I am doing this as hobby. So please forgive me because I should only look at your answers during my free times.It will take some time before I could see it and mark your work as Helpful or Answer.

How To Override Transparent Color Of Image In PictureBox
Feb 9, 2012I started off with a VERY simple form and added a picturebox item to it. The code I was following used a procedure in the Form1.vb to override the transparent color of the image:
bmp.MakeTransparent(Color.Fuchsia)
bmp was defined in the Form's "Load" section.
Now things are different. I have more than 20 picturebox items now, each created in the Form1.Designer.vb code as follows:
Me.Tile020.Image = CType(resources.GetObject("Tile020.Image"), System.Drawing.Image)
Me.Tile020.Location = New System.Drawing.Point(922, 297)
Me.Tile020.Name = "Tile020"
Me.Tile020.Size = New System.Drawing.Size(64, 64)
Me.Tile020.TabIndex = 3
Me.Tile020.TabStop = False
The image is referenced from the resources. When I run the program, I'd like all these images to have their backgrounds transparent. None of these controls is currently referenced anywhere in the code at present. What's the best way to get them to display transparently, other than recreating them as transparent .PNG's?
