Generic GDI+ error

[Alomgir Miah]

I am using image streams to set the images of my toolbar. If I close the streams, I get generic GRI+ error. On the other hand if I dont close them, the error is resolved. Any ideas?

Straight from MSDN Image.FromStream docs: Remarks You must keep the stream open for the lifetime of the Image object. I created a Bitmap helper class that copied the bytes to MemoryStream and managed the Bitmap from there. Here are some of the methods of the class:

public void Load(Stream sm)
{
    Clear();
    int len = (int) sm.Length;
    byte[] buf = new byte[len];
    sm.Read(buf,0,len);
    	
    _ms = new MemoryStream(buf);
    _bm = (Bitmap) Image.FromStream(_ms);
}

public void Load(string fileName)
{
    FileStream fs = new FileStream(fileName,FileMode.Open,FileAccess.Read);
    Load(fs);
    fs.Close();
}

public void Load(object dbField)
{
    Clear();
    if (dbField != DBNull.Value)
    {
        byte[] buf = (byte[])dbField;
        _ms = new MemoryStream(buf);
        _bm = (Bitmap) Image.FromStream(_ms);
    }
}

public void Clear()
{
    if (_bm != null)
    {
        _bm.Dispose();
        _bm = null;
    }
    if (_ms != null)
    {
        _ms.Close();
        _ms = null;
    }
}

public Bitmap Bitmap
{
    get {return _bm;}
}

Thanks a lot.
