Read Access To Physical Drive Without Admin Rights?
Feb 20, 2012I am trying to read some data from the MBR using CreateFile, but I cannot get it to work without admin rights. The code I am using is like this:

Is it possible to read data from the MBR without admin rights?
Eject USB Disks And CM_Request_Device_Eject?
Aug 5, 2010i 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...
Get List Of Fixed Disks In Computer
Jan 27, 2010I 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

How To Determine PHYSICAL Key
Feb 14, 2011I want to hook the keyboard and make some actions (in vb.net) when a specific physical key is pressed.I have found online several excellent keyboard hook dlls, but there is a problem: the hook dlls find the keycode of the pressed keys, not what physical key is pressed.So, for example, in a USA keyboard if I press the key on the left of the Right-Shif key I see the e.keycode: 191 (OemQuestion), in a italian keyboard I see the e.keycode 189 (OemMinus).This means that if I put in My.Settings the code "189", an italian user can see that has to press the key I want, an USA user see another key to press to have the same action because on it keyboard the OemMinus key is not on the left of the Right-Shift key.now the question is: how to determine univocally the keyboard keys? What do I have to put in My.Settings that determinate a specific physical key, the same for all the keyboard languages?

View 2 RepliesC# - Print A Specific Physical Size?
May 5, 2011I'm sure this is a common problem, but I haven't been able to find it.
I have a website and I want the user to be able to print a rectangle on their printer that is 3.5 inches x 2 inches. Exactly (within reason).
EDIT: To clarify - I'm looking to print a bunch of multicolored Text within a rectangle that needs to be a specific physical size. I also need to print specific shapes around some of the letters.
I'd looked into some of the .NET Printing stuff and found examples of measuring/drawing strings and shapes; but I didn't see anything that would let me specify a specific size.

DB/Reporting :: OLE Database Access - Move My Programs And The Database To Another Computer And Hard-disks
Apr 21, 2008I 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?

Jun 18, 2010What I'm looking to do is 'hook' a physical drive connected to the system so I can process data coming through the API before it's written to the disk.

Getting Physical Path Of File In Project Directory?
Dec 15, 2011I am using Environment.CurrentDirectory to get the current directory, i.e. "D:ChuttuProjectsLICinDebug"
But, I want to remove "inDebug"
How can I do that? Or is there any way so that I can get the directory up to "LIC"?
Actually this is my connection string:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|LIC.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
But when I use this and try to insert data into the DB, the data is not inserted. When I use the connection string with a physical path it starts working:
Data Source=.SQLEXPRESS;AttachDbFilename=D:Chuttu VBProjectsLICLIC.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
I am trying to get the physical path of the mdf file and use it in the connection string.
EDIT:
This piece of code works fine:
Private Sub save()
Dim con As New SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=D:Chuttu VBProjectsLICLIC.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True")

Obtain Physical Path Of Specific Website
Sep 18, 2009I have a web application (built as a product) that contains an XSL stylesheet that I'd like to use in a console application I've written in VB.Net in support of that web application. Is there a way to automatically determine the physical path to where the web application is installed? I know that the IIS Metabase holds this information, I just don't know how to access it.
What I have is the path to the web site. For example: [URL]. I'd like to look up in the IIS Metabase (on a specific server) to find the physical path
(For example: c:inetpubwwwrootmyapplicationfolder)
Is this possible from a console application running on either that server or even another server? (assume the account running the process has full admin rights).
Saving Data In A DataTable To The Physical Database?
Jan 31, 2011I've been looking at this problem for a while and can't see what I'm doing wrong. I need an extra set of eyes. The business problem that I am trying to solve is the following:I have a table that contains a list of auction items that are displayed in a datagridview. I have another table that has a list of bidders. At the end of the auction I need to update the Winners table with the bidder number and item number of the auction item. To do this, I display all of the auction items and then let the user enter the bidder number and winning bid amount in the datagridview. When finished, the user clicks on Save and the information is pulled from the datagridview and saved in the Winners table.
I have a datagridview (AuctionItemsDataGridView) that uses the auctionitems table from my database as its source. I add the BidderNo, WinningBid and BidderName columns to the datagridview when the form is loaded. There are 3 types of auction items so I prompt the user for the type of auction items to display using a combotextbox (CategoryComboBox). When an auction category is chosen, I load the auction items for that code into the datagridview. I then load the winners from the winners table into a WinnersDataTable (WinnersDT). For each item in the datagridview, I check if there is a corresponding item in the Winners Table. If there is then I populate the BidderNo and WinningBid columns of the datagridview (I also populate the BidderName). So far all of this works. The problem is when I make a change to the datagridview.If I enter a bidder number and winnng bid amount the data is not being saved to the physical database table. To save the data I perform the following:
For each item in the datagridview, check if a Bidder Number is entered. If a bidder has been entered, I check to see if there is a corresponding winners record in the WinnersDataTable for the current item. If yes, I enter the bidder number and winnng bid amount in the table. If there isn't a record, I add a new one. After looking at each item I call the Update method on the WinnersDataTable.
Public Class Winners
Dim BidderDT As DataTable
Dim WinnersDT As DataTable

Resize A Form , Its Controls According To User's Screen Settings And Physical Monitor Size?
Nov 19, 2010I am creating an application for a company and this CD will be distributed to hundreds of people. Many users will have different computer screen size and different screen settings such as their resolution set to 1024 x 728 and their monitor size 17" inches.
I noticed when I loaded the application on a different computer with different settings the application was to big for the screen and did not work. I notice that lot of other programs from microsoft resize their controls and text but never knew how they did it. How can I resize the form and control according to the user's setting.
