DivX register-app won't start under 64 bit OS

The DivX register app is hardcoded to use the System32 folder as path for Rundll32, which of course doesn't exist on a 64bit system. So when running Vista 64, you'll have to use a command similiar to this:

C:\Windows\Syswow64\rundll32.exe C:\Windows\System32\dtu100.dll,dtuSerialRunDll 7B63B2922B174135AFC0E1377DD81EC2

Vista network slowdown when using media apps

Vista throttles networkspeed to keep multimedia viewing glitch free - but they have missed that we'rent using 286's no more...

To disable the "feature"

Regedit:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioSrv

Key "DependOnServices" - edit the list, remove "MMCSS"

Quit regedit, start MSCONFIG -> Services -> Disable "Multimedia Scheduler"

Reboot and Njoy networkspeed even when listening to a MP3

Virtual PC 2007 Console window won' t show

Happened me last nigh, my VPC:s ran just fine but I could only access the console through the traybar.

Evidently, the options.xml file has been damaged, or at least there are faulty values in it.

You have to view hidden systemfiles to find:

C:\Users\UserName\AppData\Roaming\Microsoft\Virtual PC\Options.Xml

find the console section and you will find that the layout parameters are way off, like max(int). Change the left/right etc to 10 or something similar and the window will pop back to the desktop. You must close all VPC:s and console to be able to save the options file.

Data controls ASP NET 2

When working with the data controls in ASP NET 2 - like GridView and DetailsView you are always best of if you use templated columns. The simplest way to acomplish this is to start of with DataBound fields then just right click them and choose "Convert to template field.

There are two major reasons for using templated fields:

1. You get predictable names, like CTL_MyView_TemplatefieldName - which is good if you need to access them via Javascript.

2. From code behind you can get your fields like this:

TextBox t = (TextBox) ((DetailsView)sender).FindControl("tbStatusDetailTemplate");

Application Wide(Windows Forms) - capture Keys(like functions keys)

1) Define constants

const int WM_KEYDOWN = 0x100;
const int WM_KEYUP = 0x101;

2) Add interface, IMessageFilter

public partial class Form1 : Form, IMessageFilter

3) Make message interceptor

public bool PreFilterMessage(ref Message m)
{
Keys keyCode = (Keys)(int)m.WParam & Keys.KeyCode;
if (m.Msg == WM_KEYDOWN && keyCode == Keys.F8) // We'll just handle F8 here
{

MessageBox.Show("Key: " keyCode.ToString());
return true;
}
return false;
}

4) Add message interceptor to forms message handling(in Forms constructor)

Application.AddMessageFilter(this);

Enjoy!

You have to run the above command(Vista) to grant HTTP on URL xxx for user XXX before you can start a WCF-server.

If you use DualHTTP you have to open the firewall for the incoming requests from the client.

Week of year

// Updated 2004.09.27. Cleaned the code and fixed a bug. Compared the algorithm with
// code published here . Tested code successfully against the other algorithm
// for all dates in all years between 1900 and 2100.
// Thanks to Marcus Dahlberg for pointing out the deficient logic.
// Calculates the ISO 8601 Week Number
// In this scenario the first day of the week is monday,
// and the week rule states that:
// [...] the first calendar week of a year is the one
// that includes the first Thursday of that year and
// [...] the last calendar week of a calendar year is
// the week immediately preceding the first
// calendar week of the next year.
// The first week of the year may thus start in the
// preceding year
const int JAN = 1;
const int DEC = 12;

const int FIRSTDAYOFJAN = 1;
const int THURSDAY = 4;

// Get the day number since the beginning of the year
int DayOfYear = date.DayOfYear;

// Get the numeric weekday of the first day of the
// year (using sunday as FirstDay)
int StartWeekDayOfYear = ( int ) ( new DateTime ( date.Year, JAN, FIRSTDAYOFJAN ) ).DayOfWeek;

// can be incremented by one.

// If week number is still 0, it means that we are trying to evaluate the week number for a

Winform 2.0 annoyance on XP

Having problems seeing your design when running you windows forms app on XP? Looks good in VS design, but colorless and dull in runtime?

Then you need to make this fix to the main method:

[STAThread]
static void Main()
{
Application.EnableVisualStyles();
// Calling DoEvents after the above method call seems to fix this issue
Application.DoEvents();
Application.Run(new Form1());
}
