Editing the registry in c++?

Hello, I was wondering if I could get some help on this one. If anyone have some time to set of. You see I am trying to learn how to creat a file in the registry with c++.

I know the basic in c++ and some of .NET VB. And in vb is this the code that I use:

Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click

       Registry.SetValue("HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Test", "Test9999", 1)

   End Sub

So if any one oush that button they are going to creat a key in the registry named Test9999. So how do I do this in c++? I have been taking a look here: http://msdn.microsoft.com/library/default....gsetvalueex.asp

And tryed lots of thing like this:

int main ()

{
LONG RegSetValueEx(HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\, Test999, 0, REG_DWORD, test);
}```

our this:

```markup
#include <windows.h>
#include <iostream>


int main ()

{
   HKEY hKey;
      DWORD dwDisp = 0;
      LPDWORD lpdwDisp = &dwDisp;
      CString l_strExampleKey = "SOFTWARE\\Microsoft\\Exchange\\MSExchangeAdminCommon";
      CString l_strDWordSample = "DWORDSample";
      DWORD dwVal = 100;

      LONG iSuccess = RegCreateKeyEx( HKEY_CURRENT_USER, l_strExampleKey, 0L,NULL, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &hKey,lpdwDisp);

      if(iSuccess == ERROR_SUCCESS)
      {
           RegSetValueEx (hKey, l_strDWordSample, 0L, REG_DWORD,(CONST BYTE*) &dwVal, sizeof(DWORD));
      }
}

But what ever I do, do I only get error when I am trying to bulid it. So can someone help me on this? Whit write me an example our something? Thanks

I would try running a DOS command via C++

int main()
{
System("regedit test.reg");
return 1;
}

make test.reg the registry you want to add. This should work. haven't tried it, but its how you do it the command prompt or with batch files.

and for more registry fun: http://www.robvanderwoude.com/index.html that has all about doing regedit with DOS and command and batch files

I see, but I want to make it with c++ to learn more about it. BUt thanks for help the link you gave me was nice to have. Lots of infomation. :)

if you need more help man. pm me or something and i can help out. i thought that had answered your question. what else are you looking to figure out/learn?

Include <windows.h> and use the following example for adding to run, works with others: Code Sample

RegOpenKeyEx(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", 0, KEY_SET_VALUE, &hKey2 ); RegSetValueEx(hKey2, "Name of File", 0, REG_SZ, File_Source_Path, sizeof(File_Source_Path)); RegCloseKey(hKey2);

edit http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/registry_functions.asp for your registry funtions.*

Hope it helps

Eh, no… BUt thanks for trying to help me :) This is the code:

#include <windows.h>
#include <iostream>


int main ()

{
RegOpenKeyEx(HKEY_CURRENT_USER,
"Software\\Microsoft\\Windows\\CurrentVersion\\Run",
0,
KEY_SET_VALUE,
&hKey2 );
RegSetValueEx(hKey2,
"Name of File",
0,
REG_SZ,
File_Source_Path,
sizeof(File_Source_Path));
RegCloseKey(hKey2);
}

And this is the error log

What am I doing wrong?

The code I posted works with Dev C++

Its the only thing I use o_O I am not the best at C++. I had found that off of http://www.rohitab.com/discuss/index.php?showtopic=8936&hl=registry

Rohitab is where I get all of my information on programming C++.

I see but why dosent the code work for me?

Read the documentation for christ's sake, the error itself is pretty self-explanitory.:xx:

What am I doing wrong? Just read your errors. You clearly haven't declared hKey2 or File_Source_Path as identifiers, and the last error just ties in with the first. You should learn at least a little C++ before trying out code and asking about errors.
