Never mind the following does the job:

Dictionary<object, object> cControl = new Dictionary<object, object>();

Thanks anyway Smile | :)

Hey, me again Smile | :)

You can also do this if you need access to the key value as well:

SortedList<String, Control> myList = new SortedList<string, Control>();
foreach (KeyValuePair<String, Control> pair in myList)
{
    String thisIsTheString = pair.Key;
    Control thisIsTheControl = pair.Value;
}

Please don't keep posting ASP.NET questions in the C# forum. And, perhaps if you actually posted some code, we could work out your problem ?

Hi,
I have 10 radioButtons and when I first time select radioButton1 on GUI everthying works well, I see the method radioButton1_CheckedChanged_1 has been invocked. But after when I select radioButton2 I see first that the radioButton1_CheckedChanged_1 has been invocked an after that radioButton2_CheckedChanged_1 and same behaviour for the rest of radio buttons.
Can somebody help me with the isuue that when I select a radio button then the right radiobutton method is going to be invocked.

Thanks in advanced

The event is called 'checkedchanged', it's working as advertised. When radio1 unchecks, the check has changed, so the event is called. The object passed into the method is the control that raised the event, so you can use that to check if the control is checked or unchecked ( or when you have one event per control, you can access it directly )

Hi,

In regards to your query I would suggest you to try the following code snippet:
The following code example demonstrates initializing a ListView in detail view and automatically resizing the columns using the AutoResizeColumn method. To run this example, paste this code into a Windows Form and call the InitializeResizingListView method from the form's constructor or Load event handler.

-----------------------------------------------------------------------------------------------------
private ListView resizingListView = new ListView();
private Button button1 = new Button();

private void InitializeResizingListView()
{
// Set location and text for button.
button1.Location = new Point(100, 15);
button1.Text = "Resize";
button1.Click += new EventHandler(button1_Click);

// Set the ListView to details view.
resizingListView.View = View.Details;

//Set size, location and populate the ListView.
resizingListView.Size = new Size(200, 100);
resizingListView.Location = new Point(40, 40);
resizingListView.Columns.Add("HeaderSize");
resizingListView.Columns.Add("ColumnContent");
ListViewItem listItem1 = new ListViewItem("Short");
ListViewItem listItem2 = new ListViewItem("Tiny");
listItem1.SubItems.Add(new ListViewItem.ListViewSubItem(
listItem1, "Something longer"));
listItem2.SubItems.Add(new ListViewItem.ListViewSubItem(
listItem2, "Something even longer"));
resizingListView.Items.Add(listItem1);
resizingListView.Items.Add(listItem2);

// Add the ListView and the Button to the form.
this.Controls.Add(resizingListView);
this.Controls.Add(button1);
}

private void button1_Click(object sender, EventArgs e)
{
resizingListView.AutoResizeColumn(0,
ColumnHeaderAutoResizeStyle.HeaderSize);
resizingListView.AutoResizeColumn(1,
ColumnHeaderAutoResizeStyle.ColumnContent);
}
-----------------------------------------------------------------------------------------------------

Hope this helps Smile | :)

Set the ColumnHeader width to -1 or -2 to get autosize according to heading or content.

//create new worksheet
Microsoft.Office.Interop.Excel._Application _appClass = new ApplicationClass();
_appClass.Visible = true;

_appClass.Caption = "Exported ECS Errors";

Microsoft.Office.Interop.Excel.Workbook wbk = _appClass.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);

wbk.Worksheets["Sheet1"] = "Mvelo";

Please explain what the Spreadsheetgear is/provide me with a solution to this code.

Reading XML which has colon in Element

17-Apr-08 20:43

Hi,

I'm using following code

<br />
XPathDocument doc = new XPathDocument(XMLFilepath);<br />
XPathNavigator nav = doc.CreateNavigator();<br />
// Compile a standard XPath expression<br />
XPathExpression expr; <br />
expr = nav.Compile("/"+root+"/"+name+"/"+ElementName);<br />
XPathNodeIterator iterator = nav.Select(expr);<br />

It is working well except following

<br />
<root><br />
<br />
       <wafer> </wafer><br />
</name:device1&gt;<br />
</root><br />
<br />
</code><br />
<br />
after few anlysis i found that name:device : does this flaw. What this solution to read such kind of XML files?<br />
<br />
Thanks in advance.

Re: Reading XML which has colon in Element

name:device1 means that name is a namespace. You then have to define the name namespace. Or fix your XML format.

There is no such direct method available in .Net, this can be done using FlashWindow API function which is available in User32.dll file.

Calling this function will require you to use InteropServices class.

Check following link for a tutorial –

normalize int data

17-Apr-08 20:28

Hello everyone,

I have a couple of integers, and I want to find a simple and effective way to normalize them into range [0, 1]. Any ideas and code refer?

thanks in advance,
George

Re: normalize int data

Christian Graus17-Apr-08 20:33

Christian Graus

17-Apr-08 20:33

If you only have two ints, then one is 0 and one is 1, right ?

You need to turn them into floats if you want to normalise in a range that includes decimal points. Then you need to decide what the low and high point of the range are, and do the divide/etc on each one to build your normalised list

Re: normalize int data

Do you have any pseudo code or tutorials for that idea?
