RegJump Vb

regmon used to have a neat feature where it could open regedit and navigate the treeview to the registry key it was displaying.

turns out Mark spun it off into its own command line utility as well called regjump

here is a quick vb version that works with xp and newer regedits. (note my blog eats forward slash chars and im to lazy to fix it)

the old xp compatible regmon version used to send keys to the treeview. (tested doesnt seem to work with current regedit)

        // Open path
	for ( ch = RegPath; *ch; ++ch )  {
		if ( *ch == '[back slash blog gobble gobble yumm yumm]' )  {
			UINT vk = VK_RIGHT;
			SendMessage( regeditHwnd, WM_KEYDOWN, vk, 0 );

			// wait for slow displays - 
			// Regedit takes a while to open keys with lots of subkeys
			// when running at high color depths 
			if( devMode.dmBitsPerPel > 8 ) Sleep(REGEDITSLOWWAIT); 

		} else {
			UINT vk = toupper(*ch);

			SendMessage( regeditHwnd, WM_CHAR, vk, 0 );
		}
	}


Looks like this project has a tweaked version which is probably working (2015)
