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);

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

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

Hello, this is Sergey

I have a problem with dataGridView:

One of the predefined columnes has type DataGridViewComboBoxColumn with predefined items.

When i'm adding new row

int index = datagrid.Rows.Add();

and after that trying to set default value in DataGridViewComboBox,

DataGridViewCell dgvc = datagrid.Columns[2].CellTemplate;
dgvc.Value = "High";// it has index = 0 in items of column
datagrid.Rows[index].Cells[2] = dgvc;

it throws messages that its incorrect. I've tried in other ways, searching for information, nut i didn't find it

Could you help me to set this shirt default value to combobox and get then it back?

Thanks,
Sergey

Custom Listbox with Only Left Key Enabled

29-Aug-07 20:36

Hi, I need a Listbox with only Left Key Event. All other keys should be ignored.
I've Inherited the Listbox Control and overridden its OnKeyUp(...) (and similar) Methods and provided them with
following Implementation

protected override void OnKeyUp(System.Windows.Forms.KeyEventArgs e)
{
if( e.KeyCode == Keys.Left )
{
// My Code
}
else
; // Do Nothing
//No Call to base.OnKeyUp(e) Made Anywhere in this method
}

Still My Custom Listbox Implements its Default Key behaviour and handles all the keys (Up, Down, PageUp, etc...)
Please Advice

Thanks...

Hello,

You have to override OnKeyDown where you check the KeyCode, and also OnKeyPress.
Not calling the base. method will not work in this cases, you will have to set the e.Handled property to true.

public class SpecialListBox : System.Windows.Forms.ListBox
{
    public SpecialListBox()
    {
    }

    protected override void OnKeyDown(KeyEventArgs e)
    {
        if(e.KeyCode != Keys.Left)
        {
            e.Handled = true;
        }
        base.OnKeyDown (e);
    }

    protected override void OnKeyPress(KeyPressEventArgs e)
    {
        e.Handled = true;
        base.OnKeyPress (e);
    }
}

Hope it helps!

All the best,

Martin

Thanks for the Way, Martin...

Actually I wanted to Shift the Focus to some other control whenever the user pressed Left on My CustomListBox. So all I did was...

protected override void OnKeyDown(System.Windows.Forms.KeyEventArgs e)
{
if( e.KeyCode == Keys.Left )
{
MyControl.Focus(); // Do What I Want to For Left Key Press
e.Handled = true;
return;
}
else // for Other Keys do your Default Handling
base.OnKeyUp(e);
}
protected override void OnKeyPress(System.Windows.Forms.KeyPressEventArgs e)
{
e.Handled = true;
base.OnKeyPress (e);
}

How to impose expiry date to various documents using C#

Dear All,

Please guide me about imposing Expiry date to MS Office files (.doc, .docx, .xls, .xlsx, .ppt, .pptx, InfoPath) using C#, such that if the file has expiry date today, it should not open tomorrow.
I know, we can do it if the IRM client is installed on client machine, but to avoid burden on the user we are told to do it through code.

Regards
Sachin

There's no way to implement that kind of functionality. The filesystem would have to support it and, of course, it doesn't. You'd have to write your own file system extension (not in C#) to do this.

Thanks for your reply.
But I think its possible, as its already done by one vendor of our client, since its their IP, we do not have access to the source code. That DLL imposes all IRM rights that includes expiry date too.

Sachin

One of two things can do this. Either the application supports it, or the file system supports it.

For the file system, you'd have to write an extension to the file system.

For an application, you'd have to write some kind of Add-In for that application that replaces the app's load/save functionality.

You can't just "throw in" an expiration date into the document properties and expect that to work on every instance of the application. For instance, throwing an expiration date into a Word document doesn't do anything unless that copy of Word has this extension installed. BUT!! What's to stop the user from opening the document on a copy of Word that DOESN'T have the extension installed?? NOTHING!! The document must be encrypted somehow to get around this kind of functionality limitation. You need to stop other copies of Word from opening up the document.

As for how to replace the load/save functionality, I have no idea.

Thanks for the reply Dave,
Well, I got some clue from MOSS ECM Starter Kit, where they have given some information about custom IRM protector.
If I get anything concrete out of it, will definitely share.
If any one has already done some work on it, please do share.
