  • Windows disk full trouble...

    On my laptop I was constantly running out of diskspace. All the time I compressed everything I could, but I kept running out of diskspace. I was getting really pissed why this was happening so I searched my disk for big files. The Windows temp directory on my Windows Server 2003 (c:\windows\temp) was full of 100MB big files, and they kept comming. I wondered which application was creating them, so I used filemon.exe from http://www.sysinternals.com. A great utility to monitor all disk access. It happened to be the dw20.exe application, an error reporting application from Office 2003 (which is also installed on my machine!). After searching Google (searching at Microsoft makes no sense!) I found a link to an article at http://www.microsoft.com/office/ork/xp/beta/five/ch19/MntB02.htm. It describes how to turn off error reporting (don't know what is going wrong, everything seems to work, but errors kep getting generated I think).

    I tried to follow their directions, but could not find the mentioned Group Policy Object Editor. Finally found it: execute mmc.exe from run... Do Add/Remove snap-in, select Add and select “Group Policy Object Editor“. Now follow the instruction in the article, and set Disable error reporting to Enabled. Now error reporting is disabled! The registry settings also described in the article did not work for me...

    Finally I can get back to developing again!

     

  • WSS documentation on MSDN seems RTM

    I am already programming on WSS/SPS2 for a few months, but I was missing a lot of documentation on it. A lot of sections in the documentation were still empty or incomplete. But he, that is the fun in programming on beta software. The online documentation on MSDN on WSS seams to be updated to the RTM version, it is now much more complete!!

    Start at http://msdn.microsoft.com/library/default.asp?url=/nhp/Default.asp?contentid=28001891&frame=true for all online documentation on the new SharePoint platform!

  • Pragmatic ADO.NET...

    I by a lot of books. Not to read from cover to cover, more to skim through, and then use as a reference. Once in a while I read a book from cover to cover, especially if I am enjoying a luxuous vacation in our house in Italy. Writing from my vacation address (and it really has been a while that I posted something here) I would like to point you to a book I just finished: Pragmatic ADO.NET, by Shawn Wildermuth. Great introduction to ADO.NET with clear examples and not to thick!! I hate those 2 Kg Wrox books with elaborate, not to the point, example code. This books gives you a flying start.

  • Using IE within a Windows Forms application

    Changed this blog posting into an article. It's just too long for a post, and might be handy to keep around...

    Everytime I'm busy with something I think: hmmm, would be nice to share this.. but one way or the other the time just isn't there. I will try harder...

    I'm working on a simple windows forms app to browse some of the hierarchies of SharePoint Portal Server 2003, and besides a tree control on the left side  I needed a browser control at the right side to display some detail information in HTML. Of course you can add the Internet Explorer dll shdocvw.dll to the toolbox so a wrapper is generated... but there are some problems left like what values to pass for all those parameters and how do I handle events that are raised.

    One of the .Net world famous programmers Lutz Roeder, developer of Reflector (http://www.aisto.com/roeder/dotnet) did write a class encapsulating the Internet Explorer Active-X control that is used in Reflector. Although he did not publish the source code (as far as I know), this file came on the web one way or the other. I found it at the following link:

    The code follows below, together with some code how to use it....

    And now some example code describing how to use it... I created a window with a tree control at the left, the Internet Explorer at the right and a splitter in the middle so the controls can be resized dynamically...


    using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using System.Threading; using Reflector.Library; namespace SPS2Admin { ///  /// Summary description for SPS2Admin. ///  public class SPS2Admin : System.Windows.Forms.Form { ///  /// An Internet Explorer embedded browser instance is used for displaying detail information. ///  private HtmlBrowser _htmlBrowser; ///  /// The tree for navigating SPS structures. ///  private TreeView spsTree; private System.Windows.Forms.MainMenu mainMenu; private System.Windows.Forms.MenuItem menuItemFile; private System.Windows.Forms.MenuItem menuItemView; private System.Windows.Forms.MenuItem menuItemFileConnect; private System.Windows.Forms.MenuItem menuItemFileExit; private System.Windows.Forms.MenuItem menuItemViewWebs; private System.Windows.Forms.MenuItem menuItemCurrentCredentials; private System.Windows.Forms.MenuItem menuItemCreateProgram; private System.Windows.Forms.MenuItem menuItemNavigator; ///  /// Required designer variable. ///  private System.ComponentModel.Container components = null; public SPS2Admin() { // // Required for Windows Form Designer support // InitializeComponent(); _htmlBrowser = new HtmlBrowser(); _htmlBrowser.Parent = this; _htmlBrowser.Dock = DockStyle.Fill; Splitter split = new Splitter(); split.Parent = this; split.Dock = DockStyle.Left; split.BackColor = SystemColors.Control; spsTree = new TreeView(); spsTree.Parent = this; spsTree.Dock = DockStyle.Left; _htmlBrowser.Navigate("http://www.macaw.nl"); } : : } }


    I did display only some relevant part of the code... this should do the job, no "design time" control, but hey.. who needs that!

    Update:
    I got a solution from Julien CHEYSSIAL to resolve the problem concerning controls like textbox,
    combobox which were displayed with the old looking style while using the WebBrowser in a Windows Form application.
