Alternate Method To Copy Files To UNC Path?
May 7, 2009
I created a VB.NET Winforms app a while ago that printed drawings. The way it did this was to copy files from a network share to the folder for a plotter's que. This plotter would automatically just print anything that was dropped into this folder, which was specified with a path like \Btltmkeng_plt_q. I would do this by using the System.IO.File.Copy method. This worked well, until the company switched to a new printer. When my app copies the file, the printer only prints blank pages.
However, if I open two Windows Explorer apps, and manually drag the file from the network folder to the printer que folder, it works! This proves that the printer can handle these files if they are properly copied. Therefore, I was wondering if there were "alternate" methods for copying files in VB. I tried using the My.Computer.FileSystem.CopyFile method, but that just error out saying it could not find the target folder. Is there another method that more closely resembles what happens when files are copied using Windows Explorer?

I have a program written in VB.net 2003 that are folks run under alternate credentials. Inside the app there is an option to open a UNC path to a network share. We were running Windows XP SP3 and IE6. The code is simple just a call to the explorer.exe with /root,\UNCPath. After installing IE 8 onto the machine this no longer works. Best I can tell the code is still working but now being executed in non interactive mode so nothing opens up. You can however see a new spawned explorer.exe running under the system account for each attempt at opening a UNC Path. Any ideas what IE8 could have done to cause this behavior?

I am writing a program that stores filenames, along with a lot of information about the files in a database. I need to be able to open these files in three different programs from my application. One of these programs, AutoCAD is the default program for the files, but the other two are more difficult. These two need to open the file in a program that is not the default for the file type. Eventually, I'd also like to allow users to point the application to the instance of AutoCAD, MasterWorks, or FeatureCAM that they want to open. I have found articles that explain how to open a file in a default application and articles that tell me how to open any application with a file name, but only 1 suggestion of how to control the program used to open the file. For some reason I cannot get AutoCAD to recognize the file I feed in if I use this method though, so I think it's wrong. This is the method I found that doesn't work:
Start("D:Program Files (x86)AutoCAD 2007acad.exe", file)file is a variable that contains my file name. Since this works fine when I take the program path out, I know the filename is correct, but AutoCAD says it is not.

I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

I have VB project and I tried to use PUBLISH feature.It seems to create nicely some kind of setup program, but the setup program does not ask where to copy files (it does not seem to copy filesto target machine "PROGRAM FILES".)Is this setup program somehow different from usual installers?
NOTE: I want that app files are installed to Hard disk( from USB stick source)Is the signing recommended or necessary? My App is pretty simple, its just using access DB + printer api, should I still sign?

I want to copy a file from a UNC path (ex: \comnamedirnamefilename.txt) to a local destination (c:outputdir)
I have no compile errors, but when I run it, it throws an exception (System.IO.DirectoryNotFoundException). I'm absolutely sure the destination existst (it's referencing the destination directory). I've tried doing it with system.io.file.copy(source,dest)and my.computer.filesystem.copyfile(source,dest). Same result either way.

I'm creating what should be a simple copy and paste type of program. Basically you put text in the textboxes and click the copy button to copy it to the clipboard. I have a text file attached to format the text when it is copied. With that in mind, when I run the program(debug), i can successfully use it once. But, after clicking the "reset" button to clear all of the text boxes for another use, I fill in the information as normal, I click the copy button and i get this popup titled "ArgumentException was unhandled" followed by the error "Illegal characters in path".
Here is the code >
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ReadText1 As New System.IO.StreamReader(vartextfile1)
vartextfile1 = ReadText1.ReadToEnd

i got to do a program in VB.NET that copies a file from a pc to a usb device. I use the method System.IO.File.Copy(FileToCopy, NewCopy) in which i have to specify the destination path. The problem is that when i change pc the destination can change: for example in my pc i read my USB pendrive o G: and on my friend pc i read the usb pendrive on E:. How can i solve that? May i specify a general path to my USB giving it a name or anything similar?

I'm trying to copy/move (whichever works in the end) a picture from my resources in my program, to the startup path.
However, when i try it, it tells me that the file could not be found.
System.IO.File.Copy(My.Resources.Image, PATH, False)That will turn up with an error telling me that the value of type Bitmap cannot be converted to string. So i figured i would try to put a .ToString behind it, and then i'll get the File Not Found error.

Part ot my program is to simple copy a range of cells ~21 000 rows from one WB (oSH) and copy it to another WB (oSHOut).I've red a lot of posts,tried a lot of variants, but nothing helps..Strange here is that if I copy less than 8500 rows, the paste to the destination range is OK.But if I copy the whole range ~21000 rows, vb.net trigers an error - "Copy method of Range class failed".So I tried to do this in several parts - 1 row to 8000, 8001 to 16000 ect.The first copy-paste works OK, on the secon - there's an error.[code]

How can I search the local disk for a file type and copy the full path to a new location. I am trying to write a backup program that will copy all pst files to the server while maitaining the structure, so if there is a pst located in "C:pstuserpersonal1.pst" it would create the folder "\serverpstuserpersonal1.pst" and copy the file to the correct location. I would need it to do this for each pst on the hard drive no matter the location. The user running the program will not have admin rights, so it will need to skip files it cannot access.
