Windows 7 SDK Installation success or error status: 1603

Aug 03 2011

Today my team lead asked me to install FxCop 10 for static code analysis(which is available as part of Windows 7 SDK.) in our projects. As I am using Visual Studio Professional edition, the inbuilt option for Static code analysis is not available. I downloaded the Windows 7 SDK ISO from http://www.microsoft.com/download/en/details.aspx?id=8442 link. And I am able to start the installation. After some time, I got a wiered error like the following -

Windows 7 SDK - Installation Error

Windows 7 SDK - Installation Error

After checking the log file I found a line like this. Installation success or error status: 1603. I searched for this particular error and it was a generic error, sometimes it was related to low disk space. I tried the installation serveral times and everytime I got the same error. Then I modified the installation options, I un-checked all the VC++ related options; which is not required for me. And its worked :) Later I found some problem with the VC++ compiler options and Microsoft has released a patch for it. And you can down load it from http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=4422

Happy Coding :)

Upload multiple files using Silverlight

Jul 17 2011

Early this year I wrote a post about creating a File Uploader using Silverlight and WCF. And today I got a question from one forum, about to create uploader for multiple files. And here is source code, I am just modified my eariler source code slightly to select multiple file.

OpenFileDialog openFileDialog = new OpenFileDialog();
//Hard coding filter - You can read it from client side too.
openFileDialog.Filter = "Image Files|*.jpg;*.bmp;*.png";
openFileDialog.Multiselect = true;
bool? result = openFileDialog.ShowDialog();
if (result.HasValue && result.Value)
{
    spProgress.Visibility = System.Windows.Visibility.Visible;

    Service1Client client = new Service1Client();
    client.DoUploadCompleted += (o, p) =>
    {
        if (p.Error != null)
        {
            MessageBox.Show(p.Error.Message);
        }
        else
        {
            MessageBox.Show("Done");
        }
    };
    client.DoUploadAsync(CreateUploadData(openFileDialog.Files));
    client.CloseAsync();
}

And here is the helper methods.

private Dictionary<string, byte[]> CreateUploadData(IEnumerable<FileInfo> infos)
{
    var files = new Dictionary<string, byte[]>();
    foreach (var fileInfo in infos)
    {
        files.Add(fileInfo.Name, ReadFileContents(fileInfo.OpenRead()));
    }

    return files;
}

private byte[] ReadFileContents(Stream stream)
{
    using (Stream sr = stream)
    {
        byte[] contents = new byte[sr.Length];
        sr.Read(contents, 0, contents.Length);
        return contents;
    }
}

And here is the change in WCF Service.

[OperationContract]
public void DoUpload(Dictionary<string, byte[]> files)
{
    string folder = @"C:\Uploads";
    foreach (var file in files)
    {
        using (FileStream sw = File.OpenWrite(Path.Combine(folder, file.Key)))
        {
            sw.Write(file.Value, 0, file.Value.Length);
        }
    }
    return;
}

Sometimes if you are uploading too many files with large size, you may get some error like Not Found, maxArrayLength exceeded. You can fix this error by addingin the web.config file.

How to fix Error Code 29506, While installing SQL Management Studio Express on Windows 7 x64

Jul 15 2011

Today I started installing SQL Server Management Studio express on my Windows 7 x64, and I started installing it, after few seconds, I got an error message like this

This installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 29506

Error Code 29506, While installing SQL Management Studio Express on Windows 7 x64

Error Code 29506, While installing SQL Management Studio Express on Windows 7 x64

My initial thought was may be it is because of some problem with my downloaded installer. I downloaded it again and still the problem exists. Then I tried it with commandline(cmd), with Run As Administrator option and its worked :)

Image cropping control in C# for Windows Forms

Jul 03 2011

This post is also inspired by a SO post – Image Cropping Control for WinForms with Selection Rectangle. I had done a similar implementation using VB.Net long back but I couldn’t remember the implementation. :( Today I tried it again and here is an implementation, which helps to crop an Image using selection rectangle.

namespace dotnetthoughts
{
    using System.Drawing;
    using System.Drawing.Drawing2D;
    using System.Windows.Forms;

    public class CustomPictureBox : PictureBox
    {
        private Rectangle _rectangle;
        private Point _startingPoint;
        private Point _finishingPoint;
        private bool _isDrawing;

        public CustomPictureBox()
        {
            Cursor = Cursors.Cross;
            _startingPoint = new Point();
            _finishingPoint = new Point();
        }
        protected override void OnMouseDown(MouseEventArgs e)
        {
            base.OnMouseDown(e);
            if (e.Button == MouseButtons.Left)
            {
                _isDrawing = true;
                _startingPoint = new Point(e.X, e.Y);
            }
            Invalidate();
        }

        protected override void OnMouseUp(MouseEventArgs e)
        {
            base.OnMouseUp(e);
            if (e.Button == MouseButtons.Left && _isDrawing)
            {
                _finishingPoint = new Point(e.X, e.Y);
                if (e.X > _startingPoint.X)
                {
                    _rectangle = new Rectangle(
                        _startingPoint.X <= e.X ? _startingPoint.X : e.X,
                        _startingPoint.Y <= e.Y ? _startingPoint.Y : e.Y,
                        e.X - _startingPoint.X <= 0 ? _startingPoint.X - e.X : e.X - _startingPoint.X,
                        e.Y - _startingPoint.Y <= 0 ? _startingPoint.Y - e.Y : e.Y - _startingPoint.Y);
                }
                else
                {
                    _rectangle = new Rectangle(
                        e.X <= _startingPoint.X ? e.X : _startingPoint.X,
                        e.Y <= _startingPoint.Y ? e.Y : _startingPoint.Y,
                        _startingPoint.X - e.X <= 0 ? _startingPoint.X - e.X : _startingPoint.X - e.X,
                        _startingPoint.Y - e.Y <= 0 ? e.Y - _startingPoint.Y : _startingPoint.Y - e.Y);
                }
            }
            _isDrawing = false;
            Invalidate();
        }

        protected override void OnPaint(PaintEventArgs pe)
        {
            base.OnPaint(pe);
            using (Pen pen = new Pen(Color.Red, 2))
            {
                pen.DashStyle = DashStyle.Dash;
                pe.Graphics.DrawRectangle(pen, _rectangle);
            }
        }

        public void CropImage()
        {
            Bitmap bitmap = new Bitmap(_rectangle.Width, _rectangle.Height);
            using (Graphics graphics = Graphics.FromImage(bitmap))
            {
                graphics.DrawImage(this.Image, 0, 0, _rectangle, GraphicsUnit.Pixel);
            }
            Image = bitmap;
            //Removing the rectangle after cropping.
            _rectangle = new Rectangle(0, 0, 0, 0);

        }
    }
}

We can modify this control by adding nice to have features like

  1. Overlay while cropping.
  2. Drag and Re-size the selection Rectangle.

Happy Coding :-)
