Dialog Box - How To Copy Files With Multithreading
Jul 11, 2009
I've been looking at multithreading because I have been trying to make my own dialog box and it seems it might be the only solution. When I used dialog.show, there was no way to cancel the copying operation without the program finishing the current file it was copying (which I found to be annoying), and if I used dialog.showdialog, the program wouldn't continue executing code until I closed the dialog box. So I defined the thread and gave it a sub procedure to execute. But it turns out I can't directly access the main form's controls now. I read all about delegates and invoking and haven't come up with an answer to simply GET a value.
Here's the code in question:
Private Sub TransferFiles()
For FileCount As Integer = 0 To Me.ListBox1.Items.Count - 1
Dim NewName As String = Me.ListBox1.Items.Item(FileCount).Tag
Next
End Sub

I have some dialogs in one resource file that I want to copy into another project. I opened the .rc file in the IDE and I can right-click on the dialog I want and I can choose the copy command. But when I right-click in the resource view, whether on the .RC entry or the "Dialog" entry below it, the paste command is disabled. Nor does drag&drop work.
How do I do this in Visual Studio 2010?

In Access or Excel, for instance, if I have a file named MyFile I can create an entirely new copy of it by going to File --Save As--; and pronto I have another File named ,say, MyFile2 while retaining my original file - MyFile - in its entirety.My question is: can I do same in VB? If I have a Solution named, MySolution, can I use the Save As dialog to create an entirely new copy of it while retaining the original Solution? If yes, how and if no, how do I do it?

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?

Is there a dialog box for loading files, the same as the savefiledialog? I know how to load a file once I know it's name/location, but how do I open up a box to allow my user to select a file from the drive?

I am creating a program that uses XML files and saves them automatically when the user updates information. When I have XElement.Save("Name.xml") it saves the XML file in the same directory as the EXE. What I am trying to do is allow the user so select the location of the XML. Also is loading XML files through the loaddialog box basically the same way as XElement.Load("Name.xml")?

im used to C programming.
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveAsToolStripMenuItem.Click
timedate.Stop()[code]......
The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".

I am currently developing the 'solution' through the UI Dialog properties of VB 2008, so my application can be installed onto a computer .It works ok, installs successfully, creates the desktop icon, start menu icon and programs folder....... BUT, when I go into the Control Panel, the uninstall option is there, but not with my own icon it uses the Windows default icon.

i have a vb script that is imbeded in an html page (hta). when i use the common dialog flags = cdlOFNAllowMultiselect the file list is present in the filename object and are separated by a space. however when i use dialog flags = cdlOFNAllowMultiselect Or cdlOFNExplorer the files that i selected on the dialog box, are not present in the filename object. the only thing that's there, is the path to the files. here's the code:
Const cdlOFNAllowMultiselect = 512Const cdlOFNExplorer = 524288Set ObjFSO = CreateObject("UserAccounts.CommonDialog")ObjFSO.Filter = "All Files|*.*"ObjFSO.FilterIndex = 1
ObjFSO.InitialDir = "c:" ObjFSO.Flags = cdlOFNAllowMultiselect or cdlOFNExplorerinitFSO = ObjFSO.ShowOpen selected_files = ObjFso.FileName msgbox selected_files
how can i get the files names?

I have a system which needs to be secure which streams relatively large documents from a webservice to a proxy (Web site) whch then grabs the stream and pushes this to the client. This works but there are some issues where it seems the response is not being pushed until the entire stream is complete? whether this is the case Im not sure have run charles and until it completes it is "Waiting for response".
The documents are currently PDF but it needs to handle many other types for the future. The octet stream etc is mostly testing related, how to get the Dialog to show - saying save as? for the large files the little ones don't matter to much but the big ones leave a big waiting period with no response.

Can you not copy files from your resources? [code] I don't get any errors but I do get an exception saying it couldn't find the file. I want to do this other than supplying the directory that it is located on on my computer because I'm not sure it it will work on other peoples computers if i have the path of the file set as "C:UsersMike.Mike-PCDocumentsVisual Studio 2010ProjectsJava IDEJava IDEResourcesCompiler.bat".

In my ignorance, I thought I could subscribe to any host, so I chose hostmonster, and copy files from Visual Web Developer to it, thereby creating my first website. Wrong! Hostmonster is linux-based, so the files won't copy without assigning an index page at the site. The rep at the host said that linux doesn't read the language(s) I've been using to develop pages, Visual Basic and C#.

I am trying to copy files from one drive to another. I am a novice at Visual Basic, but here are the facts. I am running Windows XP, and Microsoft Visual Studio 2008. I work at a business where we need to move a small amount of data every Sunday, literally about 100k, a few small files. I'm trying to cut and paste the files as we will not need them in the main file any longer. There's also the network issue, I'm trying to pull them off a LAN, onto my computer, specifically the G: drive to the C: drive.
This is what I put so far:

I need to create an application (or find one application) that copies files from a computer to another, across the internet to create automatic backups. The target computer is a company server to which i have phisical access. The "source" computer(s) (several computers in several clients, that we - company, have also phisical acess). Solutions like teamviewer, PcAnywhere,... just don't fit because we already use them but they don't allow to create automatic backups. how can i copy files across the internet, using VB .NET, from one computer to another?

I am wanting the most efficient way to copy a file with a progress bar updating the copy percentage.
This is the standard copy code I am using:
System.IO.File.Copy(source,target)
This is very fast and efficient. However, I cannot report the copy percentage.I have tried many functions that read and save a file by opening up the filestream and then looping while reading/writing the data. This enables me to report the progress.[code]...
What is the best/efficient way to copy a file showing the copy progress?
