[C#]How would i go about opening a .reg file through code?

I want the .reg file to execute as if the user had clicked it. Meaning less complications and things to go wrong that would be my fault. How would i go about doing this?

I am pretty sure, but can't check right now, but I believe you can shell out and run REGEDIT with command lines to merge a .reg file automatically.

Let me see what options REGEDIT has on the commands line and let you know.. I'm on a work conference ATM.
http://www.ss64.com/nt/regedit.html

Code:

Code:
[B]REGEDIT [/B]

  Import, export or delete registry settings from a text (.REG)  file
 Syntax
      Export the Registry (all HKLM plus current user)
      REGEDIT /E [I]pathname[/I]

      Export part of the Registry
      REGEDIT /E [I]pathname[/I] "RegPath"

      Import a reg script
      REGEDIT [I]pathname[/I]

      Silent import
      REGEDIT /S [I]pathname[/I]

      Start the regedit GUI
      REGEDIT

      Open multiple copies of GUI (XP and 2003 only)
      REGEDIT -m

Key
   /E : Export 
   /S : Silent Import
I believe you can shell out and issue

`REGEDIT /S "C:\\PATHTOFILE\\FILETOMERGE.REG"

I have never used it but this is the way I have seen it done.

Code:

Code:
using System.Diagnostics;
static void Main ( string [] args)
{
    Process regeditProcess = Process .Start( "regedit.exe" , "/s "   +args[0].ToString());
    regeditProcess.WaitForExit(regeditTimeOut);
}
Not sure if thats what you want. Like poster above, /s for silent mode, and then the path.

Come on Licht, you should be able to answer these questions yourself!

Windows has a function called ShellExecute() and ShellExecuteEx(). Both let you manipulate a file as you would with your mouse.

http://msdn.microsoft.com/en-ca/libr...53(VS.85).aspx

http://msdn.microsoft.com/en-ca/libr...54(VS.85).aspx

Code:

Code:
HINSTANCE ShellExecute(      
    HWND hwnd,
    LPCTSTR lpOperation,
    LPCTSTR lpFile,
    LPCTSTR lpParameters,
    LPCTSTR lpDirectory,
    INT nShowCmd
);

Parameters

hwnd
[in] A handle to the owner window used for displaying a user interface (UI) or error messages. This value can be NULL if the operation is not associated with a window.

lpOperation
[in] A pointer to a null-terminated string, referred to in this case as a verb, that specifies the action to be performed. The set of available verbs depends on the particular file or folder. Generally, the actions available from an object's shortcut menu are available verbs. The following verbs are commonly used:

edit
Launches an editor and opens the document for editing. If lpFile is not a document file, the function will fail.

explore
Explores a folder specified by lpFile.

find
Initiates a search beginning in the directory specified by lpDirectory.

open
Opens the item specified by the lpFile parameter. The item can be a file or folder.

print
Prints the file specified by lpFile. If lpFile is not a document file, the function fails.

NULL
In systems prior to Microsoft Windows 2000, the default verb is used if it is valid and available in the registry. If not, the "open" verb is used.

In Windows 2000 and later, the default verb is used if available. If not, the "open" verb is used. If neither verb is available, the system uses the first verb listed in the registry.

lpFile
[in] A pointer to a null-terminated string that specifies the file or object on which to execute the specified verb. To specify a Shell namespace object, pass the fully qualified parse name. Note that not all verbs are supported on all objects. For example, not all document types support the "print" verb. If a relative path is used for the lpDirectory parameter do not use a relative path for lpFile.

lpParameters
[in] If lpFile specifies an executable file, this parameter is a pointer to a null-terminated string that specifies the parameters to be passed to the application. The format of this string is determined by the verb that is to be invoked. If lpFile specifies a document file, lpParameters should be NULL.

lpDirectory
[in] A pointer to a null-terminated string that specifies the default (working) directory for the action. If this value is NULL, the current working directory is used. If a relative path is provided at lpFile, do not use a relative path for lpDirectory.

nShowCmd
[in] The flags that specify how an application is to be displayed when it is opened. If lpFile specifies a document file, the flag is simply passed to the associated application. It is up to the application to decide how to handle it.

SW_HIDE
Hides the window and activates another window.
SW_MAXIMIZE
Maximizes the specified window.
SW_MINIMIZE
Minimizes the specified window and activates the next top-level window in the z-order.
SW_RESTORE
Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when restoring a minimized window.
SW_SHOW
Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT
Sets the show state based on the SW_ flag specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application. An application should call ShowWindow with this flag to set the initial show state of its main window.
SW_SHOWMAXIMIZED
Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED
Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE
Displays the window as a minimized window. The active window remains active.
SW_SHOWNA
Displays the window in its current state. The active window remains active.
SW_SHOWNOACTIVATE
Displays a window in its most recent size and position. The active window remains active.
SW_SHOWNORMAL
Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when displaying the window for the first time.

You expect too much of me. I'm highly inexperienced.
