I need to write an application that does the following, and I figured it was a good opportunity to write my first VB.Net application:
1. Get the list of fixed disks in the computer
2. For each disk, recurse through all its directories and sub-directories looking for filenames that match a given regex (eg. MyFile.d{3})
3. If found, hash this file to get a unique ID, eg. MD5 (just to check if this file already exists elsewhere)
4. If this file hasn't already been seen elsewhere on the disk, copy it to a central directory
I'm working on a program that lists all of the files on all of the drives on my computerI'd comments. To use the program Start a new Windows Forms application and replace the code on Form1 with the code listed here.
I have the following code in my app to show free space / disk size and SMART status for a hard disk How can I modify it so that it lists all disks and shows the above info for each one
I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?
I have been a VB user for quite a long time starting from dos-basic types. But only now I encountered with a quite a newb problem :) I tried to search MSDN for it for about a few days and at the end I have to ask this question here because I could not find anything about it.
From time to time I use functions or subs where one parameter is a word from a defined list.
E.g.
private function my_function(byval THE_PARAM as string) as ..........
where THE_PARAM could be "work", "home", "bus", etc. 5 words all together.
How can I define a function so that when I use it on the text of the program I had a hint not just like "THE_PARAM is a string", but I had a choice of those pre-defined words, so I could choose a word from that list.
I have two datagridviews in my app. They're related. When there is no record in the parent datagridview, I select the "New Row" and then press the Add Button in the child datagridview's bindingnavigator. Then I get that exception:
InvalidOperationException: Item cannot be added to a read-only or fixed-size list.
I know why this happens.When I add new record to child datagridview, parent datagridview's new row loses focus and then delete row. So this error occures.How do I prevent my program from this exception. Remember, it's only occures if there is no record in the parent datagridview.
i have been looking for a way for my application to 'safely remove hardware' or to eject the USB key specified, the application detects the removal and arrival of new devices but i am stuck on being able to eject them. So far my research has lead me to using setupapi.dll and CM_Request_Device_Eject and i have declared
Private Declare Function CM_Request_Device_Eject Lib "setupapi.dll" Alias "CM_Request_Device_EjectW" (ByVal dnDevInst As IntPtr, _ ByRef pVetoType As PNP_VETO_TYPE, ByVal pszVetoName As IntPtr,ByVal ulNameLength As Integer, ByVal ulFlags As Integer)
As Integer I usually code in asp for web application and have no idea how to use these types of unmanaged functions I made my function that takes the drive letter to eject by parameter
Public Function EjectDevice(USBDriveLetter as string) As Integer 'TODO USE CM_Request_Device_Eject() to eject the drive End Function
I found pinvoke.net: cm_request_device_eject (setupapi) this info on pinvoke for CM_Request_Device_Eject() but i am clueless on how it works and the vb.net section looks portly documented...
i tried several ways to monitor the File System of one of the external drives that are connected to my PC using the FileSystemWatcher. But nothing seems to work..[code]
With the following code I can list the display name of all software installed on a local machine.
'Declare the string to hold the list: Dim Software As String = Nothing
'The registry key: Dim SoftwareKey As String = "SOFTWAREMicrosoftWindowsCurrentVersionUninstall" Using rk As RegistryKey = Registry.LocalMachine.OpenSubKey(SoftwareKey)
'Let's go through the registry keys and get the info we need: For Each skName As String In rk.GetSubKeyNames() Using sk As RegistryKey = rk.OpenSubKey(skName) [Code] .....
What I need is to get the FileName to be used to start the application like notepad.exe and not just the displayname Dim p As New System.Diagnostics.Process p.StartInfo.FileName = filename & ".exe"
is it possible to have the open programs on my computer viewed in a list, and have the abbily to minimize and restore if so, what are the codes for it and what do i have to attach it ro (butten etc) it is for my OS i am making.
How can this be done using Visual Basic 2010? Is there a class or method that I would use to accomplish the same thing or would I have to read the registry path into an array as you do with vbscript? My application will be ran on the local computer just so you know this information is not being gathered from across the network. I have been looking for awhile and haven't found anything that will work so far.Once I have the user profiles from the computer, I will populate this list into a drop-down combo box.
This has to be simple, but can't find the answer.I want to display a list of all files from a folder in a listbox. Easy..., but I want to display only the filenames without their paths.
For Each foundFile As String In My.Computer.FileSystem.GetFiles("C:My Folder") ListBox1.Items.Add(foundFile) Next This gives me list looking like that: C:My Folderfile1.txt C:My Folderfile2.txt
Is it possible to create a folder that spans over many hard disks?in such a way that the application considers it as a standard folder but the data are distributed on more than one hard disk?
get a list of printer's (name,port,model) from a computer over the network. I know how to list my own, but it's from querying the Win32_printer object on my machine, I need to be able to do something similar on a remote machine.
i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main() ' Data buffer for incoming data. Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.
What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.
i have encountered a problem, i want to access the data coming to the computer from the in-built bluetooth module of a computer on windows platform, this data has been sent by a remote bluetooth module say a by an autonomous device (just like a bluetooth mouse connecting to the computer). The to be sent is in the form of numbers and i need these to manipulate on the computer.
I have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,
So I have three questions. 1: Is it possible? 2: How would I go about access the feed? 3: How would I send it over the network?
My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.
I need to copy a file from a local computer to a remote computer on the network, if i try to use File.Copy without logon i get the following error:"Logon failure: unknown user name or bad password."How do I provide user name and password for file copy?
