Hi,

Below is the code sample which I got from online resource but it's suppose to work with fullframework, but when I try to build it using C# smart device, it throws exception saying it's out of memory. Does anybody know how can I fix it to use on compact? the out of memory exception when I make the second call to VerQueryValue which is the last one.

thanks,

    [DllImport("coredll.dll")]
    public static extern bool VerQueryValue(byte[] buffer, string subblock, out IntPtr blockbuffer, out uint len);

    [DllImport("coredll.dll")]
    public static extern bool VerQueryValue(byte[] pBlock, string pSubBlock, out string pValue, out uint len);    
    //
    private static void GetAssemblyVersion()
    {

        string filename = @"\Windows\MyLibrary.dll";
        if (File.Exists(filename))
        {
            try                {

                int handle = 0;
                Int32 size = 0;
                size = GetFileVersionInfoSize(filename, out handle);

                if (size > 0)
                {
                    bool retValue;
                    byte[] buffer = new byte[size];
                    retValue = GetFileVersionInfo(filename, handle, size, buffer);
                    if (retValue == true)
                    {

                        //success = VerQueryValue(buffer, "\\", out blockbuffer, out len);
                        success = VerQueryValue(buffer, @"\VarFileInfo\Translation", out blockbuffer, out len);

                        if(success)

                            int k = Marshal.ReadInt16((IntPtr)p);

                        }    
                    }
                }
            }
            catch (Exception err)
            {
                string error = err.Message;

        }
