View 5 Repliesi am using an unbound datagridview so i can dynamiclly add rows. all that is working fine. but the grid is not is the location i have coded.. i am using the defualt form as a base then coding the unbound stuff in.. should i just create a blank class file and do everything? the only problem i am having is the grid must bees in the correct location according to the pixel point that i have given it. Right now it is placing the grid at point (0,0) no matter what point is entered on the line for location. so what am i missing??????

I have 2 group box components and both are same size,font,location and visible is false. When i click button2, the groupbox1 won't appear(the group box2 is on bottom n group box1 is on top).
Example:
button1
groupbox1.visible=false
groupbox2.visible=true
button2
groupbox1.visible=true
groupbox2.visible=false
Because i want to show the different,so the location have a little different(actually both are same location). I think my code is no problem. The problem i guess is both component cannot locate at same location?
we have a user that my program works fine for.. and another that it just crashes for.. they get this error
"You cannot start application <App_Name> from this location because it is already installed from a different location."
then they run it up again and it comes up.. and then just closes..in reading some stuff online it says its a framework 2.0 sp 1 issue ?these pc's have 3.5, but my program uses all 2.0 stuff..so is this a 2.0 sp level issue ? or should I make my programs start to use framework 3.0 instead ?
I was using this old method of creating a bunch of rectangles when I need to get the location of a certain point within a grid so I could draw images on the grid. The thing is, I don't want to use rectangles, I want to be able to just round the location as if I were using rectangles. I need it to be able to round the point (66,70) to (50,50) so if you can imagine a grid and the mouse position being within that square in the grid, I need to get the location of the upper left corner of that square.

i am trying to copy a dll from one location to another. i have a combobox from which i select a option then i want the program to copy my dll to another location acoording to the option i have selected. But Vb doesn't seem to copy it.it stays the same. for experiment i tried to copy a image. it worked perfectly.
does that mean i can't copy it.
I have encounterd a problem when trying to re-enstall a program i have writen in vb 2008.I get the following message:"You cannot start application Shell from this location because it is already installed from a different location."This program is to be used on many workstation computers and i need to be able to update any changes by just reinstalling the program, no uninstalling needed first. If the program was installed from a cd first and needs to be updated from a flash disk this error will be a problem, if the update is from a cd as well then there is no problem.Is there a way to change the installation package to ignore where the program installs from and just update itself?

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:

Now I have a folder in my project I would like to copy to an optional location. How do I set the "Folder from" const to a location inside my project and how can I set an optional location to copy the folder to at runtime?
Try to understand:
1. User Downloads Application
2. User copies files to either desktop or my documents (lets say desktop)
3. User Opens application
4. User clicks the copy button (which is then supported by the COPY code)
The problem is that the copy code supports a Location such as; FileCopy C:UsersAdminFile.txt, E:File.txt
When the user copies the Files to desktop (lets say DIM), they have a different username so if they click Copy the copy code was set for C:UsersAdmin not DIM. I would like the code to be general so whoever copies the files wherever (Desktop, C:, Documents) and they click the copy button, the file is then copied to the Disignated Location.
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.FileName = "Capture"
savefiledialog1.Filter = "JPEG (*.jpg;*.jpeg;*.jpe;*.jfif)|*.jpg;*.jpeg;*.jpe;*.jfif|PNG (*.png)|*.png"

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've been working on some code to rename files and have being doing so by copying them to the same location under a different name and then removing the original. When I do this for files I use the code ...
Dim file As New System.IO.FileInfo(lstFiles.SelectedItem.ToString)
Dim strNewFile As String
Dim strRename As String
Dim strMask As String = ""

This will obviously not work as it will try to copy the folder into itself which is not allowed.
I saw a post from 3 years ago (copy folder content to other location) that looked like the "state of the art" way to copy a folder was to just copy all the files recursively. Has vb.net 2008 introduced a function to do this? I still dont see a System.IO.Directory.Copy...
