Program Involving Moving Files From
Apr 21, 2012I am making a program that takes files (inside their folders) and copies them into a selected file path. For example, I plug in my jump drive, run my program and it copies my files on the jump drive over to my PC. Now my program does this but it takes the files inside each folder in my jump drive instead of creating a folder for each one in my jump drive. The result is a mess of files in the selected pathway in my PC.I went and created variables in My.settings so that you can save the file path even after you close the program. I just want the program to copy the folders(with the files in each folder) in my jump drive and move them over to my PC.I am using this program copy the files from my jump drive over to my PC, because I save a lot of work on my jump drive and I need to back it up often.

Search For Multiple File Extensions?
Mar 12, 2010How can I write this
Path = "C:"
For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.10") _
And For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.09")

VS 2010 : Delete All Files With The Same Name But Different Extensions?
Jun 3, 2010I'm trying to delete all the files in the same folder that have the same name but different extensions, such as CurrentWallpaper.bmp, CurrentWallpaper.jpg, CurrentWallpaper.png, without putting them in a separate folder. How could I go about doing this? I tried doing
Dim bg As String = dir + "" + Login.UsernameTextBox.Text
Kill(bg + "CurrentWallpaper.*")
but it didn't work. PS: I would also like to use the same technique for loading the image as a background image instead of having to do this:
Try

Open External Files With Unknown Extensions?
Jan 25, 2007I'm writing a program that allows users to view certain files using a DataGridView as the selection method I can do most of that just fine. Here's the part I'm having trouble with: I want to open the files using whatever program they have associated with the file extension. After researching it (on these forums), I determined that I should use the Process.Start() method. However, Windows throws an Win32Exception if there is no association to the filetype, and I want it to show the "Open With" dialog instead, and I can't figure out or find how to do that.

Validation Check Involving ASCII?
Mar 14, 2012i'm new to this site and i'm hoping there's someone out there that can help me with this problem. I'm doing a course in visual basic 2010 and having real trouble understanding some aspects of it. Here goes -
I need to do a validation check on a users inputed string. The users input is called Test_data and it needs to be exactly 10 characters long and must only use the letters " a " to " f "
I know to check that the string is exactly 10 characters long by the Len function, and i have that working.BUT - how do i check whether the users inputed string uses the letters a to f ? I thought it would involve something to do with ASCII, but i would have no idea how to form a validation check using ASCII.

Searching Multiple Files In Multiple Sub-folders
Mar 30, 2010I'm developing an application to help law enforcement retrieve and analyze logs and other files left by the use of Pidgin (a multi-protocol messenger client). Right now I'm nearly done, but I want to add the ability to search chat logs for user-defined words or phrases and I don't even know where to begin.
Chat logs are stored as html documents in a folder/sub-folder/sub-folder/sub-folder fashion, where each sub-folder can have dozens of sub-folders inside of it, and the final sub-folder can have dozens if not hundreds of chat logs. If anybody could point me in the right direction, I'd be very grateful.
(Also, this is the first program I've written since about 2005, and I'm essentially teaching myself VB as I go. If you'd like to see what I've cobbled together so far, you can find the program here.)
Communications :: Involving Cross Threads In .NET 2005?
Feb 8, 2010My application need to communicate with my self made device through serial port. I have to change the selected index of Tabs when I press a button on my device. I have Form1, Form2, Module1 Form1 Contains the Serial Port Control. Form2 contains the Tab which needs to be changed. When I press a button on device them, the button pressed is stored in an integer form in a global variable.The Interrupt for the Serial Port directs the control to the module1 where I decide using Select Case that what index of which TabControl I have to select.Depending on that, I change the Index of the required Tab.
PROBLEM:cross thread exception is fired as soon as the control reaches the statement where I Modify the SelectIndex property from the select case at Module1.While, on my other PC, the SelectIndex property is changed, but the next tab is not shown.
BUT, if I put all this code in a button control, and try to activate from there, then it works perfectly. However, I have to navigate through the tab controls using my self made device.I searched a lot on net and came across a solution which describes that we have to use delegate function and invokeRequired methods to ensure that the procedures run on the same thread.I am not able to decide that where exactly shoud the code for delegates and all be written, in form1, or form2, or module1.Also, in the hit and try that I did, I always got the value of InvoleRequired as False.
Here is the part of Code that I wrote for Delegates
Code:
'Form 1 is BLINDHELPER_SIGNIN
'form 2 is BLINDHELPER_USER
' I have defined these at Module1
Public Delegate Sub DeleToManageTabs(ByVal tb As TabControl)
Public Sub manage_Tabs(ByVal tab As TabControl)
MsgBox(tab.Name)

After using this code also, there is no change in working of my application.
Deployment Involving DLL References And Global Assembly Cache (GAC)
Jun 19, 2009I created a Windows Application using VB.NET 2005 Express Edition.In my project I have two references to DLLs from a 3rd part product, so that I could access its API (Ascent Capture 7.5 from Kofax if you needed to know).For the two references, I have set the Copy Local property to False, and in the app.config file I am using assemblyBinding to reference one of the DLLs.When I build the application and then execute the EXE file in the inRelease folder, everything works fine. When I do a publish and try to run the setup.exe application that is created, I get an error message that basically states the DLL I referenced in the app.config file needs to be installed in the GAC.So why does my application work fine from the Release folder without having to do anything to the GAC, but I cannot install using the setup.exe from the Publish? I would like to use the setup.exe because I need to install this on other machines than my own.

For Each Loop - Involving LINQ Query When Reading Form Controls
Dec 8, 2009I have a form with a tab control, containing a small number of tab pages. I'm writing a sub procedure to clear the controls within a groupbox for the selected tab. A selected tab will only ever contain ONE groupbox and within a groupbox will be command buttons, labels, text boxes and possibly a combobox. The first block of code below firstly finds the groupbox within the selected tab. The next part loops around all control type and if of type texbox clears the text.
Now hears the head scratcher/confusion it error's with :-
Unable to cast object of type 'System.Windows.Forms.Button' to type 'System.Windows.Forms.GroupBox
Which I don't understand as I cant see where Im converting objects simply looping through all controls and then ONLY if type of control is textbox then clear text.

'are within a SINGLE groupbox and clear contents or reset to default value
