I have a country map in a picture box with provincial divisions. I can fill each province on mouse over by calling following floodfill function on my pictureBox MouseMove event[code]...
View 1 RepliesI researched this and found I had to use something called "ScreenToClient" [URL]...what I want to do is to have a picture box that I can just get the coords from easily (for example 0,0 bottom left hand corner)
So how do I get that to work? (im guessing something like comparing the picturebox size to the form size then working it out but im not quite sure how to do that.)
I have written an vb.net application, named vbapp.exe. And I would like to use vbapp.exe to shell an external .exe file and this external .exe will create a file in the folder in which the external .exe file is located.However, the external .exe file will not recognize its own folder, on the contrary, it will think that its own folder is where the vb application, vbapp.exe, is located.

View 1 RepliesI am trying to create a program that will be able to recognize handwritten numbers in a picture. Right now, the program locates a rectangle that the numbers are in. The numbers will generally be in the range between 0 and 9000. I have found some stuff about ink recognition, but I dont think that is the same. Also, is there anyway to be able to make the program 'learn' from the style of the handwriting? I'm using VB.net 2008

How would you make a program that recognizes your eye, or something...
dim eye as string = picturebox1
if eye = picturebox2 then
msgbox("It's your eye",64,"Yeap!")
Or if it's too complex maybe just recognize the color?
To programming and have a question with sound files. I am trying to figure out the basics and here is what I did: I created a button that is supposed to play a sound.
My.Computer.Audio.Play("C:.......file.wav")
When I click this button in my .exe file it obviously plays because I am using the computer with the above location for the .wav file. When I use the .exe on another computer it doesn't play because it does not recognize that .wav location. How do I make this work for me? Do I need to embed the .wav with my .exe somehow?
I'm trying to copy a picture from one location and paste it into another location however VB throws out the following error

Im trying to get the location of a picturebox on my form or say if location = (20,20) then this happens. The action performed by the picturebox is determined by its location i need some way of monitoring it

I was wanting to make a little game. You press a start button, and a picture moves into different spaces. If you can hit stop when the picture is in a certain spot, then you win. How do i make it so when i press the stop button, it will check to see if the picture is in the location (180, 307)?
This is what i have:

First of all take a look in here :[URL]...As you can see, in the image there're 3 items.So let's talk about the first one, the first right one. (CRAYON SHORTS)I want the picturebox to move always to the left side,After it knocks the "wall" it'll re-start all the progress.So simply, I want the picturebox to move left.

I want to get the border of the form when its load but how? Then I'll compare between the form location and the mouse ,if the mouse out of the form, the visibility is false when the mouse move or key press up /down and become in the form border, the form visibility must be true. How to find the x and y values to the form?

I am writing a program in VB 2010. My computer is an E Machines dual processor Intel Celeron running at 1.8 gb/sec with 2 GB of RAM. I have a 1680 X 1050 display and the graphics driver in the computer is fully capable of utilizing this display. I am running Vista Home Edition.
The purpose of the program is to analyze a large number of infrared and visible light images from the geostationary satellites GOES East and West. Note: These images are TIFF and range in size from 400 KB to 70 MB. The pixels are either 8 bit or 10 bit depending on the image type.
The program allows the user to select a series of images from a file folder. These images are then displayed in a picturebox. A map covering the same area is also available to the user. The user may then move the cursor, via the mouse, to a selected location on either the map or in a picture. With a left click that location in terms of image coordinates is used to compute the geographic coordinates of the selected location. These coordinates are then displayed for verification purposes. So far, all of this works properly.
The next thing I need to do is to determine the brightness value of selected pixels in the displayed image. Because brightness is related to temperature this permits a detailed examination of cloud temperature and density in each image. By making this measurement at several different wavelengths (provided by images taken at different wavelengths) the program will then compute the atmospheric extinction factor at each selected wavelength and from that derive the atmospheric transparency function.
Here is where I have run into problems. I cannot find a way to extract the pixel value from the selected X, Y values input either by cursor position or by direct entry. I have tried the various approaches described in the documentation but I either get errors or a pixel value that is unrelated to the image. The following is a section of code that I am currently trying.

i have a chart of images.. and i want to load individual images into picturebox from that chart..chart = big image, eg alphabet chart. (yes i am creating a game for my small nephew.. pictures and alphabet) now, i want to show different pieces of images into picture box. like the A box, b Box etc one option is to cut the chart into pieces, save each piece with different filename and load individual filename into picturebox.but i saw somewhere that we can use pixel location to load images into picturebox..as i recall it required two pixel location, 1 was upper left and other was lower right.. and passing that pixel locations would load the rectangular image between those pixel locations into picturebox?
View 9 RepliesI'm making a screen capturing program, and I am trying to save the image. I can do it as a 'save as' like this
save as
savefiledialog1.Title = "Save File"
savefiledialog1.FileName = "Capture"
savefiledialog1.Filter = "JPEG (*.jpg;*.jpeg;*.jpe;*.jfif)|*.jpg;*.jpeg;*.jpe;*.jfif|PNG (*.png)|*.png"
[code]....
How could I do a quick save option so that it auto saves to a certain location that the user doesn't have to choose and as a .jpg?
how I loaded my image
Dim test(100) As Image
test(0) = Image.FromFile("C: est.jpg")
now i want to put it in a picture box at location 50-50
I have a combobox that drops up instead of down. I'm setting the selected item to the one on top of the list. I'd like to move my mouse pointer to point to it, so that the user that wants to click on that item doesn't have to move his mouse. I found how to move the pointer, it is with this command:
Windows.Forms.Cursor.Position = New System.Drawing.Point(x,y)
but I need to know how to get the location of the selected item in the combobox.
The code bellow should perform a mouse click at the location the cursor is pointed, however it only activates the control from that location.

P2foodarea is a large picture box I created. I only want the apple to spawn on P2Foodarea, atm, it spawns on P1Foodarea which is very weird. P1foodarea is a whole other picture box. I even made new variables as you can see P2ax and P2ay, but it still doesn't spawn on P2Foodarea. I have even tried recreating a new picture box for P2foodarea
How can I make an autoclicker that senses when the mouse is moving and when it stops it automatically clicks. Such as every single second it checks for the mouses location and if the mouse is in the same location for 4 seconds it automatically clicks.
