Saving A Picture Without Manually Choosing The Location?
Feb 4, 2012
I'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?

I'm trying to copy a picture from one location and paste it into another location however VB throws out the following error
Exception from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED)
both locations are on my local computer. So not sure what is causing the problem.
Here's the code

Console.Title = "MOARW Programs"

I 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 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.

When I click on "New Project", under the "Name" textbox, I get no "browse" button to save the project somewhere else other than the default Document and Settings folder. But, my friend see that "browse" button under the "Name" textbox.
How can I save the project somewhere else other than the default Document and Settings folder ?

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?

This code shows me the preview of a webcam in a picture box. I want to know how to save a frame as a picture file.The code I'm currently using to save it (in the timer tick event) gives me the "Object reference not set to an instance of an object." error..Then I used a debug assert line and it gave me an error that basically says that there is no image in the picture box, while I can clearly see a picture in the picture box. Can anyone please help me write/edit the code to save it?

When I save settings for an application using My.Settings.Save it saves it in %AppData%LocalCompanyname. Because I don't want my app to be installed and I want it to be a just .exe file, and it leaves some files on that computer. I like it to be in my apps location. Can I change that default location?

I have a picture box and I tell it to appear on a random location on another specified larger picture box.
here's my code:
Code:
Sub P2_AppleMove()
Dim P2ax As Integer = CInt(Int((P2Foodarea.Width * Rnd()))) ' sets the random area of the food
[Code]....
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

We are developing applications using VB .NET as front end and SQL Server as back end. We want to store and retrieve pictures in a database. We do not want to store the pictures directly into the database but rather the path of the pcitures so that through the same paths we can retrieve them.
