Calling system command from batch

[rolypoly2308]

I am making an installation batch program where it copies the files into the correct folders and then runs a registry file to give them the correct icon. Although I need to find a way to call, I believe SHCNE_ASSOCCHANGED from SHChangeNotify API so that it can update the icon. Help much appreciated

It's true that you could update file type icons using SHChangeNotify API but unfortunately you can't call it directly from a batch file. You need a programming language to compile a 3rd party application where that API is called.

Not sure if the following would help. If you've got installed the .NET framework then you should have csc.exe on board. It's a C# compiler.
Try that ugly combination of batch and C# code to compile your own refresh tool.

refresh.bat (all in one file):

Code: Select all

/* &@cls
:: Batch code:
@echo off 

for /f "delims=" %%i in ('dir /a-d /b /s "%SystemRoot%\Microsoft.NET\Framework\csc.exe" 2^>nul') do set "csc=%%i"
if not defined csc (
  echo "csc.exe" not found, compiling impossible.
  pause>nul
  goto :eof
)
call "%csc%" /nologo /target:exe /out:"%~dpn0.exe" "%~f0"

:: call "%~dpn0.exe"
:: del "%~dpn0.exe"
pause
goto :eof

:: C# code:
*/
using System;
using System.Runtime.InteropServices;

class Program
{
  [DllImport("shell32.dll", CharSet = CharSet.Auto)]
  private static extern void SHChangeNotify(long wEventId, uint uFlags, IntPtr dwItem1, IntPtr dwItem2);
  private const long SHCNE_ASSOCCHANGED = 0x08000000;
  private const uint SHCNF_IDLIST       = 0x0000;

  static void Main(string[] args)
  {
    SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, IntPtr.Zero, IntPtr.Zero);
  }
}

Why not use something like NSIS instead.

Thanks, I will try both methods and see which one is easier/more fitting
