传一个vc++ Post文件的类

参照网上资料根据自己需求修改的一个vcActiveX与asp.net页面文件交互传输文件的类部分(不可传输大文件)

1.vc中导入头文件和cpp文件

2.vc中使用

 UpLoadFile* upfile=new UpLoadFile;
 upfile->Upload("D:\\ClassDiagram1.bmp","localhost","80","/WebApplication1/Default.aspx");

3.aspx接收处理端Page_Load中

 1            IServiceProvider provider = ( IServiceProvider )HttpContext.Current;
 2            HttpWorkerRequest request = ( HttpWorkerRequest )provider.GetService( typeof( HttpWorkerRequest ) );
 3            byte[] byteHeader = request.GetPreloadedEntityBody();
 4            if ( byteHeader != null )
 5            {
 6                byte[] byteData = new byte[request.GetTotalEntityBodyLength()-byteHeader.Length];
 7                int size = request.ReadEntityBody( byteData , 0 , byteData.Length );
 8
 9                byte[] theImgData = new byte[byteHeader.Length + byteData.Length + 1];

                for ( int i = 0 ; i < byteHeader.Length ; i++ )
                    theImgData[i] = byteHeader[i];

                for ( int i = 0 ; i < byteData.Length ; i++ )
                    theImgData[byteHeader.Length + i] = byteData[i];

                using ( MemoryStream mStream = new MemoryStream( theImgData ) )
                {
                    System.Drawing.Image img = System.Drawing.Image.FromStream( mStream );
                    img.Save( "D:\\test\\aaa.bmp" , System.Drawing.Imaging.ImageFormat.Bmp );
                    img.Dispose();
                }
            }

 

注:  以上代码在 vc++6.0和vs05 iis6 win03上测试通过 ( 附件是vc UpLoadFile类 )
