Picturebox - Images .net File Used By Another Process Error?
Jan 28, 2010
I'm writing a little program where I select a picture through an open file dialogue. When I selected a picture I want it to overwrite the current picture and display the new image. Now I don't have any problems with picking an image with a different extension. So when I currently have a .png I can select a .jpg but when I choose an image with the same extension as the current image I get an error: The process cannot access the file 'C:Users....woontypeimageschalet_foto.jpg' because it is being used by another process.
If ofd.ShowDialog() = Windows.Forms.DialogResult.OK Then
Dim sFilename As String = cboWoningtypesWoningtype.SelectedItem.ToString & "_foto" & System.IO.Path.GetExtension(ofd.FileName)
System.IO.File.Copy(ofd.FileName, Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) & "Camping
The process cannot access the file 'C:UsersdavidDesktopTest Folderdavid 2.xml' because it is being used by another process.
how do i end the prosess after I create the file? Or am I creating it in the wrong manner.The underlined line is where the error ocures.
Public Sub AddDTData(ByVal value1 As String, ByVal value2 As String, ByVal filename As String) dtUser.Rows.Add(value1, value2, Now.Date) If My.Computer.FileSystem.FileExists(filename) Then
I try to open a text file and write in some text, when i run the program it says the following error:The process cannot access the file 'D:VB projectsCategory_Characteristics.txt' because it is being used by another process.
THe code is as follows and the error hits in line :
Dim objWriter As New System.IO.StreamWriter(FILE_NAME) ----------------------------------------- Dim FILE_NAME As String = "D:VB projectsCategory_Characteristics.txt"
How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code: Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read) Dim sr As IO.StreamReader = New IO.StreamReader(fs1) sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.
My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.
Dim ScreenSize As Size = New Size(154, 83) Dim screenGrab As New Bitmap(154, 83) Dim blank As New Bitmap(100, 300)
I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
I'm trying to write text to / read text from a file, but when it's trying to execute the My.Computer.FileSystem.WriteAllText code, it throws an exception: "The process cannot access to the file "<filename>" because it's being used by another process", and the "source" of the exception is "mscorlib"Note: this is a DLL file, which is being used by an application.
I tried to use: If IO.File.Exists(My.Application.Info.DirectoryPath & "Sites_int.wblist") = True Then Kill(My.Application.Info.DirectoryPath & "Sites_int.wblist")
In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?
I am having an issue where I try to delete a file and get the error message that it is already in use. I can not seem to figure out what is currently using the file. Maybe someone here has an idea.
I'm making a program that gets the hash of anything that is downloaded from the internet. I used a filesystemwatcher to watch the "C:Users" & Environment.UserName & AppDataLocalMicrosoftWindowsTemporary Internet FilesLowContent.IE5" folder. Whenever a file is created/downloaded, it gets the hash, but... when it gets to the get hash steps, it throws the following exception:Access to the path 'C:UsersMatt tevensonAppDataLocalMicrosoftWindowsTemporary Internet FilesLowContent.IE5YDQ4IWIF' is denied.E.g.If I try to download the CCleaner.exe from the Piriform website (file for example) it'll detect it, but when it trys to find the hash of it, it says:
I have an App that saves one line of data to a textfile like this[code]... ' If I try to overwrite that file or delete it I get the error "The process cannot access the file 'c:windowsDScatalog.ini' because it is being used by another process."
I'm trying to delete a file, which prompts the error: "can not delete File in use by another process". I've been researching this for the last couple of days, and have tried every possible suggestion, I've come across, but still keep getting the error. I'm hoping someone might have a suggestion on what I need to change or rearrange in my code to get around this.
The program loads a group of files into a listbox, user selects which files to process, Each file is sent through the sub (process files) to be renamed, and then processed through external programs then removed from the listbox. Each file in the list HAS to be renamed the same in order for the external program to process it. This is where I'm getting the error message, as I need to delete the previous file before renaming the new one. Parts of my code may seem redundant, but its where I was trying every possible scenario of closing the process and or stream that's leaving the file open. [Code]
I've got an import program that reads csv files and imports the data to a sql server database. After the import I call a send email procedure which takes some arguments including the two files and adds them as attachments to a mail message, then sends the email:
I have some coding which edits my text file and saves two versions, the first version removes all multiple space with one space and saves it as a text file and the second replaces the spaces with a comma and saves it as a csv file. The problem I have is however later on when I run other code using the saved text and csv files, it looks like the processes are in use. I get the following error:
The process cannot access the file 'Path' because it is being used by another process.My actual coding:
Private OpenFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile1.txt") Private SaveFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile2.txt") Private SaveFileName2 As String = IO.Path.Combine(Application.StartupPath, "TextFile3.csv")
I have made a small program which loads a file into a listview when somebody presses the load button on the form. The user can also put information in the listview by filling in some textboxes and press on the add button.So now the weird thing is that if the user loads an empty file ( With no information in it ) and presses load on the form and after that tries to add information to the file you get a "The process cannot access the file '" because it is being used by another process" error.
The code for the load button is as followed: ( So here accountfile 2 is loaded )
Dim BinFormatter As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter() Dim FS As System.IO.FileStream Try
I want to be able to click a picturebox with an image and then load 3 other pictureboxes with images and then be able to click one of those 3 images and have it show in a bigger picturebox. How would I go about doing this? If its to confusing I will attach an example project I put together.
The title is simple and to the point: I have two images, same dimensions that I want one to fade in over the other. How do I do this without locking up the GUI?
was just wondering what i have to do to create a save button that actually works. i have a form with a picturebox. i want to create a save button called btnsave and when an image is in the picture box the user can click the save button and it will save it to a location of my choice example c drive. and the other question is how do i get the saved files to name its self in numerical order. for example: image1, image2, image3, image4 and so forth.
In this question I managed to combine two .png images into one, and then display the result in a pictureBox image.However, the pictureBox seems to scale up my image! Makes it bigger!The pictureBox size is 96x128.The two images I have combined are 96x128.The pictureBox's SizeMode is set to "Normal"
Well' I'm trying to print image from my PictureBox...this is my code for drawing image: e.Graphics.DrawImage(PictureBox1.Image, 0, 0)
But I need something more specified...when I print my document with this code, for some of those, I don't get the whole document. So I need to specify that...I need to stretch my image to my A4 page so that m.
I have made a screensaver in VB.NET. I am running into some roadblocks in the code though. The idea first was to have a ball bounce across my screens. It then evolved into spawning new balls that bounce across the screen. I then added collision detection so they would bounce off each other. Here is the problem that came up:
When said balls overlap each other, you can easily distinguish the edges of the picturebox that holds the images. I have made the background of the picturebox transparent, made the bitmap with a magenta background and made magenta transparent (for the image), but I can still see the picturebox edges when they overlap. It seems the transparency is not only making the background transparent, but giving it X-RAY vision to display not the visible area behind it, but the root background color of the form. here is a sample of the code which makes the transparencies.
Private Sub frmscr_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim bmp As Bitmap = My.Resources._smiley_face_image Dim clr As Color = Color.FromArgb(255, 0, 128) bmp.MakeTransparent(clr)
[code].....
I also tried to see if changing the image from background to foreground would help...no such luck.
i have been troubled with my resize function, I have loaded images and when each image is selected is will be displayed on the picturebox...the problem is that when i resize the image in the picturebox it throw me an error message Object reference not set to an instance of an object. I have 4 buttons left, right, up and down..here's my code for it...
I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String) Dim objRegKey As RegistryKey objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")
I have a pictureBox on my form along with two buttons (Back and Forward) but I can not find a viable method of doing what I wish to do: Scrolling through images in a folder like the default Windows Picture Viewer does with Arrow Keys.Is there an efficient way to do this?
I'm using Visual Basic .NET with Visual Studio 2010, if that matters.
I'm trying to accomplish is having a 20x20 pixel image show up multiple times as determined by the grid selected. To keep things simple, what I'm trying to do is create a 9x9 grid of a image onto a form. I'm assuming that a picture box is the way to go, but don't know how to make that happen or if it's even possible.
So it would go something like this:
2D array already assigned: Sub ShowGrid() For rw As Short = 0 To 8
[Code].....
But instead of using a text box with values, I want to show a grid of a small image file, like cup.png which is 20x20 pixels or whatever, so what would show up on the form in this case would be a 9x9 grid of the image file over and over to create a grid.
Then the next step I hope to accomplish is to have that 20x20 square picture hold the grid(x,y) value for a mouse click. So if the image at grid(3,5) is clicked, it will give me that value, 3-5.
i'm using VB.NET 2005 and mySQL server 5.0. Can i ask how do i retrieve the image from database and display images onto picturebox? mySQL column name is pictures then the data type is varchar. and how should i write on the database? eg. abc.jpg?
I would like to have a series of images displayed sequentially in a picturebox (every 10th of a second). I captured the images (image0, image1, etc) and placed them in a temp folder every 10th of a second.
I tried the following simple code, but I can only see the last image being displayed in the picture box.[code]...
