i am trying to make a program where it copies files to a certain external drive, but i cant figure out how to make it to where you enter your drive letter for the external drive and it copies it.
View 6 RepliesThe drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.
View 1 RepliesI'm working on an app that should be able to read files from an External Hard Drive or even an iPhone or iPod. I'm a beginner so it would be great to keep it simple :) I suppose I should use the SerialPort class? But I'm not sure and I couldn't make it work.
View 7 RepliesThe VB.Net program in question creates several files, adds them into a zip file (using DotNetZip), and saves the zip file into a given directory (which the user chooses). This comes out just fine. But when I use it to save directly to my USB flash drive, I can't eject the drive without shutting down the program first.I've tried disposing the zip object (from the DotNetZip library), doesn't work. I also tried setting FileIO.FileSystem.CurrentDirectory to somewhere else on the machine, still no.
View 1 Repliesapplication i'm developing in school.I am trying to make the program detect when the user copies new content to the clipboard,when this happens I want the program to check the data type,
I want text content to be written to a text file.Images can be left alone.if a file or folder is copied, i want the location of the copied file and the file name to be written to a text file.
I only really need help in getting the program to detect a clipboard modification, preferably with the AddHandler statement.
So, I'm using shell to start up an external application at the press of a button, but the application requires several other external files with it in order for it to work. How could I make it work? Note: I'm a newbie
View 7 RepliesI currently have a program that I made which opens other apps packaged with an installer. I have set the installer to install everything to the Program Files folder. However, not all computers have a C: hard drive. I have a way in which they can enter their drive letter in one form then in the next form it remembers the drive and will take them to the program. The problem is my program stores the drive letter in an xml file. On the startup of the program it looks in the xml file to find the drive letter, if there is no drive letter the form opens then lets the user set his drive letter. The xml file is stored in the folder "Math Wizard" in the Program Files folder. But if not all computers have C:Program Files I need a shortcut to the program files folder. I have been trying to use %ProgramFiles% (%Program Files% + "Math Wizardconfig.xml") but vb is saying that the % is an invalid character. Here's my code:

I am trying to write a program that deletes temp files from my entire c drive. windows 7 will not allow any file manipulation. access denied . everything works fine in windows xp. what needs to be changed in my code to allow anyone to install this program on their computer and run it without errors like this. I need to change my code to correct this not windows 7, as other people will be installing this on their systems and they can't be setting their c drives. every answer i've found online is either to change c drive to have no security or set the code to demand uac to run as administrator(which doesn't work )

I am presently using VB2010 to develop charting application.

Usually this can be repaired with check disk.

View 4 RepliesI'm trying to get a progress bar to work while it copies all files in a folder to another. I've gotten the progress bar to show and display the progress, but during the copying process the app stops displaying anything if I click away and won't display anything until it finishes copying everything. It just freezes with a ghost image in the form while it's copying. How do I prevent the app from freezing during the copying process? I can't even minimize it or move the window around. I hope I made sense. Here's my code.
Dim Files = My.Computer.FileSystem.GetFiles(.SelectedPath, FileIO.SearchOption.SearchTopLevelOnly, "*.*")

What I mean is, I would like to make an exclusive program, but I don't want it falling into the hands of someone I didn't give permission to.Or perhaps make it require a password to function, and be able to change that password for all copies whenever I want.

View 4 RepliesI have a VB.NET project in Visual Studio 2008 that I created a specialized addin for. The addin prompts the user to select a database table, takes a template form class's files, copies them to another directory within the project, and renames the form class within the copied files. It then opens the new form and adds controls to it based on the fields in the database table.
The copying of the template form causes the background compiler to give 'duplicate member' errors, such as "Private Sub InitializeComponents(...) has multiple definitions with identical signatures," even though I renamed the files of the new form and the class name within them. Sometimes these errors go away before the new form is opened, but when they stick around the new form doesn't open correctly, and it throws an error instead. I implemented some code to wait until there are zero errors in the error list before trying to open the new form. This has helped sometimes, but for some reason sometimes the errors don't go away at all until the addin is closed.
How to copy the template form and rename the copy without the background compiler ever noticing duplicate members. If that's not possible, then perhaps someone has an alternative?
Here is my code that copies and renames the template form:
Private Sub CreateDataForm(ByVal tableName As String, ByVal displayName As String) ', ByVal subDataForms As IList(Of Object))
Try
Dim dataFormClassName As String = "frm" & MakeValidName(displayName)
Dim dataFormFileName As String = dataFormClassName & cVBSuffix

What I'm trying to do is write a small program that copies a file from a USB to another directory so a program already installed on the computer can load this data.Usually copying files from one directory into another wouldn't be an issue.
[Code]...
If possible i would also like to change the code i have written so it just loads January2009.txt from the "root directory" of the USB rather than having to specify H: because if i put the USB in someone elses computer this could change to G: and then it wouldn't work.
i have this right now:
ListBox1.Items.Clear()
Dim di As New IO.DirectoryInfo(TextBox1.Text)
Dim aryFi As IO.FileInfo() = di.GetFiles("*.*")[code]......
and that displays only the file name, like text.txt but i want it to display C:/Text.txt and all the files in the subfolders too, like C:/Program Files/Test2.txt but i just get test.txt from only the c:/ .
