Hello,

The kernel32.dll provides a method called SetLocalTime:

[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
public struct SystemTime
{
    public short sYear;
    public short sMonth;
    public short sDayOfWeek;
    public short sDay;
    public short sHour;
    public short sMinute;
    public short sSecond;
    public short sMilliSeconds;
}

[System.Runtime.InteropServices.DllImport("kernel32.dll")]
public static extern bool SetLocalTime(ref SystemTime time);

Or call the System Timesetting directly over a process:

using System.Diagnostics;
 
ProcessStartInfo TimeSetting = new ProcessStartInfo(@"C:\WINDOWS\system32\rundll32.exe","shell32.dll,Control_RunDLL timedate.cpl,,0");
TimeSetting.UseShellExecute = false;
TimeSetting.WorkingDirectory = @"C:\WINDOWS\system32";
Process TSet = Process.Start(TimeSetting);
TSet.Dispose();
TSet = null;

Hope it helps!

All the best,

Martin

In the OS? Or just for your application?

I wouldn't attempt the former.

Nope. We're here to help you write your own code, not just hand over our own work to someone to play with.

Content Alignment

Hi,

I'm wondering if there is a content alignment feature inside container controls (Panel, TableLayoutPanel) . e.g. I have several controls in a TableLayoutPanel. Those controls may change their size on runtime. I want to place them into a grid (like html table) one per cell and align them to middle of the cell(horizontally and vertically). Is this possible without writing custom code ? Until now, I figured out only way that to keep them aligned is to dock-Fill them.

Hello,

Have a look at the "Anchor" property of the controls?
Maybe it fits your needs.

All the best,

Martin

It's easy to build a chat application. But a messenger like msn is far more complicated. The client should be in sync with the server. i.e: whenever you get a new message the client should be intimated. Mechanisms like polling in regular interval would be complicated,or rather may not be optimal . I think msn messenger has implemented a tcp channel for that purpose.

The benifit of the class view:

Shows all the classes include in the project.
provides the definition for all the classes used.
Faster reference if you want to go to any part of the class just double click the class name

Overall it is for better understanding of your project!

You can't start to build the complete website straight away. You have to read the book and try some samples steps by steps.. then, if you get some ideas how web application works, you can start the project... You can also participate in opensoure ASP.NET project if you wanna practice ...

Convert Font size

Lucy29-Aug-07 22:25

HI I have created an application that uses the registry.

On the application there are two textboxes and a button. When the form is loaded the first textbox displays a font that has been declared in the registry and the second text box displays the font size, again declared in the registry. The button allows the user to change the font and font size using a FontDialog. When this dialog is opened (by clicking the button), the selected font is the font declared in the registry. I also want the font size that is declared in the registry to be selected in the dialog. The font name works perfectly fine, I am just having trouble with converting the font size.

First of here is my code:

string font;

int size;

FontDialog selectFont = new FontDialog();

font = Convert.ToString(Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RegKey_test", "Font", ""));

selectFont.Font = (Font)TypeDescriptor.GetConverter(typeof(Font)).ConvertFromString(font);

size = Convert.ToInt32(Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RegKey_test", "FontSize", ""));

selectFont.Font.Size = (Size)TypeDescriptor.GetConverter(typeof(Size)).ConvertFrom(size);

if (selectFont.ShowDialog() == DialogResult.OK)

{

Registry.SetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RegKey_test", "Font", selectFont.Font.Name.ToString());

TBFont.Text = selectFont.Font.Name.ToString();

Registry.SetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RegKey_test", "FontSize", selectFont.Font.Size, RegistryValueKind.DWord);

TBFontSize.Text = selectFont.Font.Size.ToString();

}

I am unsure if I should set the variable size as an integer or a string, and then according to this how is it converted to Font.Size?

I think Size property is readonly. so, try like that..

Example 1

Label1.Font = New Font("Tahoma", 30)

Example 2

<br />
font = Convert.ToString(Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RegKey_test", "Font", ""));<br />
<br />
size = Convert.ToInt32(Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RegKey_test", "FontSize", ""));<br />
<br />
selectFont.Font = new Font(font,size);

Hi
i am using ms Glee and visual studio Graph class and i have created an ellipse and displayed on Glee gview tool so i want serialize this ellipse in an xml file
here is what i have done in creating an ellipse.

Graph g = new Graph("graph");
g.AddNode("Ellipse");
gViewer1.Graph = g;

here is where i am trying to serialise but it

XmlSerializer mySerializer = new XmlSerializer(typeof(Graph));
XmlTextWriter myWriter = new XmlTextWriter(@"C:\users\dake10\documents\jacob\motors.xml", Encoding.UTF8);
Graph g = new Graph("");
g.AddNode("House");
mySerializer.Serialize(myWriter,g);

I get this error message"Microsoft.Glee.Drawing.Graph cannot be serialized because it does not have a parameterless constructor."

You can't serialize a Glee graph object using an xmlserializer.As the exception says it doesn't have a parameterless constructor.
If your aim is to draw graph,I think still graphviz is the better choice to GLEE
