I 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.

I'm just testing things and seeing if I can get things working and if I can then I want to try and develop this into something more. So far its just a simple button1 finds all files with extension of .mp3 in C: and displays all the findings in a listbox. I then want to use button2 to copy or move (I want to see how to do both) all of the files that are in that lisbox to a directory of my choosing. Here is what I have so far.
Imports System.IO Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
I have been creating a program that copies and moves files from folder to folder; I am using this sort of code;
fileToCopy.CopyTo("path here...")
or
FileToMove.MoveTo("path here...")
My problem is, when I am copying or moving a large file, It's taking so much time and my program is hanging until all the files are completely moved or copied. How about, using a progressbar instead, so that the user will be able to see the progress of copying and moving instead of the program freezing?
i am using vb.net to program and process some files.I pick files from one folder process them and once i process them successfully i should store them in a different folder. when i do fi.move(destination folder) i get an error message saying "THIS FILE IS USED BY ANOTHER PROCESS" below is my code
I have a text file with 12 lines. Each line has different data and I want to compare line 1 with an original string, then line 2 with the original string, line 3 witht he original string and so on. Not sure how to read each line from the text file.
I'm using an xsd file for a couple of my data sets that I'm using to read access databases. While this is great, I just got a new requirement that allows the user to change the link to the access database on their computer. Is there any way to allow them to set the path while still being able to use the xsd files, instead of doing it all through code?
I am working on some software to work along side our client database and I am basaically trying to add in a basic form of File Management. I have a listbox now that displays the current contents of the clients electronic file. I am wanting to set it up so that people can drag files from anywhere onto this Listbox and move that file to the clients electronic file.
For refrence the clients folder is always situated in same place which is client filesclientID where clientID is the clients unique Id on the database.
I as seeking to move 10 file every 10 minutes from one folder to another using .NET (vb c#) I am was thinking that i could of achieve this with LINQ query, but i cant get my head around this would there be a solution with LINQ or otherwise that can select the last 10 files form or top 10 files. so that i can move only these files from Directory1 ( the big pool of files) into director 2 ( a smaller more manageable pool of files).If all fails- then i wll manually have to copy or cut to at a time.
I am having trouble opening my vb.net 2005 project from a backed up copy on a hard drive. The original files are on my old XP computer which I no longer have access to. I am trying to open the project in vb.net 2010 on Win7. I have converted the project to vb.net 2010 and when I open the file, nothing shows up, when I try to open them, it tells me the form isn't found in the project directory because it's been moved or deleted. I know that the software on the hard drive didn't back up .exe files, I'm not sure if it did back up other kinds of files. I don't want to restart the project because I've spent over a year on it and have written over 3000 lines of code on it.
I am creating a setup file using features brought by Visual Studio.I have some files which can't be removed from the application's folder. How to put the condition on it? or how to prevent user moves it after installation is done?Those files are critical (eg .dll).I already set the 'Hidden' property to 'true', but I think that is not the correct way :)So I try to find another way to do that.
I have a system that detects USB mass storage devices. I have a "list of items" listbox (ListBox3) and a list of USB's (Listbox4) When Button4 is pressed it will transfer all files in listbox3 onto the mass storage device selected in listbox4
How could I move my VB.NET application to a folder using VB.NET in the same file? Essentially, I want to be able to move my VB.NET application to the Start folder when it is executed (within the same application). Also, I want to be able to move it to the same folder on any computer, for there is no set path to the Start folder on different computers. Or I would like to just create a shortcut for my application in the start folder?
I have been working on a program on my old computer. Now, I have gotten a new computer and would like to continue to work on it there. The program is not yet finished. I would like to copy my program to my new computer. How can I do this? I tried copying the folder from my old computer to my new one and it opened the project, but I could not edit it as there was no permission given to edit it. It shows it as a read-only.
Ok so say I had a simple form with a button. This form has the TopMost set to true and when the button was clicked it would use the SendKeys. But unfortunately you have to click onto the place where you want it to send the keys otherwise it will try typing it onto itself.
Say I have a .jar open in processes, how would I make it so when the button is pressed it would switch to make the .jar the "Front"?

The bigger problem is that I can't seem to get everything involving using stream writer and reader working. If I start of with a .txt file already correctly formatted then I can display it in the list box. But adding data during run time is not proving successful.
i'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.
I would like to read each line of text from the file outputted from this block.Each line is then used with the service controller to output a list of services running on that computer.
Dim de As New DirectoryEntry() 'Name place to write file to Dim strFile As String = "C:DomainUsers.txt"
I want to go back to the input line in the four places in the code that say something like strinputmessage = strnegative or strinputmessage = strnonnumeric.I need to be able to go back to where you input the data so that the index does not increase.I tried using a GoTo <23> to go back up to the line i needed but then it gave me all these weird errors about the End and Next were missing.[code]
My 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)
[code]....
After using this code also, there is no change in working of my application.
I 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.
This is a very simple piece of code involving threading and events. I am just refreshing the old grey matter as I find myself off work sick for a period of time.
I 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.
'Loop around all controls in form, simplified that all controls 'are within a SINGLE groupbox and clear contents or reset to default value Dim groupbox = (From grpbx In tabAdmin.SelectedTab.Controls _ Select grpbx = DirectCast(grpbx, GroupBox) _ Where TypeOf grpbx Is GroupBox) [Code] .....
I would like to execute an external program within powerpoint after the presentation has loaded so i can see if its working.

I am working in excel trying to setup a function involving multiplying a cell by a set number and then having the result round to the nearest 10. Here's the beginning of my function statement fx=e3*1.026. say the result is 8654, I need it to round to 8650. Also if it comes back 8655, I need it to round to 8660. I have about 2,000 records I need to do this to so I was hoping that one formula or statement could be used for all my data.
