File Copied With FileInfo Not Able To Be Read By Shelled Program?
Jul 3, 2011
2 - Saves the server XML file it into a folder separate from the root folder of the application.3 - Deletes the local XML file in the root folder of the application.4 - Copies the server XML file to the local folder of the application.5 - Opens the application.6 - Closes the updater.Now when the application opens, it reads this XML file in the local folder. When I run it stand alone, it works fine and can find this XML file. However, my problem is when the application is opened by the updater, it can't read the XML file in the local folder. I check for this file doing File.Exists(XMLfilename) and it returns false but like I said, if I close the application and reopen it it works fine.
I'm thinking that for some reason the updater is "locking" this file so my other process can't read it? I can't close the process before I open the original application so I'm not sure what's happening here. My Update Folder is the users ApplicationData folder and the root directory of the application is in the Program Files folder.
This is my code in the updater:
Dim ImageDir As DirectoryInfo
Dim fi As FileInfo
Code is below. I am designing this code to transfer a file at a specified time. Right now, I have it sending me an email when it succeeds for test purposes. It will be only when the file copy fails later.
Here's my question: how can I get the program to wait until the file copy is complete to report success or failure? Right now I'm using exists to see if it works, but some other method of checking the file will be built in later. Eventually, this will be deployed to various locations for a bit of automated backup.
I have the following VB function which takes a FileInfo object as a parameter:
Public Shared Shadows Sub Start(ByVal filePath As FieldInfo) XmlConfigurator.ConfigureAndWatch(New System.IO.FileInfo(filePath.ToString())) End Sub
In another class I have the following code calling that 'Start' method. But VisStudio indicates there is a problem with the 'FilePath' argument that I'm passing.
Does anybody know an effective way to protect your application from being copied? I 'd like to make my application as shareware for limited numbers of trials and after that the application shouldn't not run anymore on the same PC.
Our program will start with the help of a FileSystemWatcher object. How can we check or the file is total copied, for example the file is 100 Mbyte it take a time it's ready for use. Idea:
Do While True Try N = testForUse(BigFile) If N = 1 Then Exit Do
All tutorials I read before used Extension property to get the extension of a file. How can I get the type of file as a phrase? Example: .vb is 'Visual Basic Source File'. Like what Windows does in the Properties window of a file.
I have been having problems with creating a download list of files for a downloader and was getting unexplained "File Does Not Exist" returns. My .avi files were returning found but but .exe and .txt files were getting the not exists.
I have now found by pulling in the whole directory and examining the file contents that my .exe files are showing ".exe.exe". My .txt files are showing ".txt.rtf". Wow, browsing the file directory in Server 2008 only shows a single extension. I don't see an option to display the extension as a column, just the "type". My directory looks like this:
Name Type File1.exe Application File2.txt Rich Text Document File3.avi AVI File
I had renamed some of these files, maybe I just cannot rename files. I will try using originals ans see if I am ok. Maybe I need to rename the offending files without the displayed extensions. Is this just something weird with the server browser?
Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
I encountered a serious problem while working withclipboard class in VB.NET.I want to simulate cut-copy-paste operation withmy application and Windows Explorer.User can copy files from Explorer and paste it intomy application & vice-a-versa.My question is-How can I determine if user has copied or cut the filesfrom Windows Explorer? I want to differentiate cut & copy.I am using >> My.Computer.Clipboard<<.
I have a project where I am looping thru specific files in a directory using a For Each FileInfo in DirectoryInfo.GetFiles() statement. My question is if I overwrite the current FileInfo object, will it still retain the reference to the object even though the file is no longer the same?
Code Snippet:
For Each fi In folder.GetFiles("*.idx") Dim reader As IO.StreamReader = fi.OpenText() index = reader.ReadLine() values = index.Split(",")
I have built a recursive file system crawler that amasses file system data from a file share. I use the FileInfo object to get my metrics, however, I am finding that in especially deep file structs, that the ol' 260 character MAX_PATH MS bug crops up ':8-0:'. This puts me in my angry place, since I do not seem to be able to get around it no matter what kind of programmatic tom-foolery I try.
So far, I have tried:- converting to 8.3 format --> no good path + filename STILL is > 260 (believe it or not) - tried to go with a Straight low-level API approach
What I have found is some pretty Sketchy information regarding VB implementation of the kernel32 api's in this regard (just try & find a createfile port for vb.net, I couldnt)
Anyway, I guess I was hoping that someone else has run into this pain, and knows how to make a surefire way to get a file's information (size, dates esp), regardless of how long and painful the path may in fact be...
I am wanting to create a large amount of files all copied from a single original file. I then have a list of names in a listbox that each of of these files will rename to. However I am getting an error saying that the file already exists in the save location even though the files are saving to a totally different folder...
code below.
Dim Counter As Integer = listFileNames.Items.Count Do Until Counter = 0 System.IO.File.Move(txtOpen.Text, txtSave.Text)
So I transitioned over to Win 7 64 bit, and am starting to incorporate it into my program. I understand that My.System.FileSystem.SpecialFolders.ProgramFiles will resort to x:Program Files if the host system is 64 or 32 bit. However, if the host is 64, and the program is 32 bit, one would need to acess x:Program Files (x86).
My question is this:How can I test an executable to see if it is 32/64 bit, and then apply the proper program folder?
I am making trying to make a program that can read the file information directly from a specified file, but I am having a lot of difficulty reading things like file comments.An example of this can be found in windows XP when you alternate / right click on any file and click on properties. You'll get a lot of extra information.Now I have a few questions about this.
1.Can this information even be read in VB.NET 2.If so how 3.If not do I need to create some kind of data file to store the file information
But I need to wait for it to wait before letting it to go on to the next thing like clear cookies, which would be: Shell("RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2")
Does anyone know if you can actully read a file from your visual basic program? i just built a program and an updater with it and tried it on a few free hosts, but everytime i upload the version.txt and navigate to it i get a bad exstension error in the browser, anyone know how i can override this or of a free host that allows me to to it?
A VS 2008 desktop .NET program needs to open a PDF file and read its contents as data. That is, the program must scan through the PDF file searching for certain text. The program will not merely open the PDF file and display the contents using a control such as an ADOBE Reader control. It has to actually read the individual data within the PDF.
How can a .NET program read data within a PDF file?
The project I'm working on is to write a program that requests an integer from 1 through 12 and then list the gifts for that day along with that day's cost. The program should also give the total cost for all twelve days combined. The items and price are in a text file called TwelveDays.txt.An example output is shown below:
The gifts for day 3 are: 1 partridge in a pear tree 2 turtle doves 3 french hens Cost: $249.99 Total cost for the twelve days: $78,100.30
How to read in the file and add the day costs together.
