Hi!

If you want to learn how to use RegEx, just search in google. Helpful is one of the regex trainer which let you test your regex search-string before you use it.
But here is an example to catch URLs:

// Clear old data in listboxes
listBox1.Items.Clear();
listBox2.Items.Clear();

// example HTML document
string lsCode = "<HTML><BODY>test1<BR><A HREF='LinkURL1'>Link1</A><BR>test2<BR>" +
"<A HREF='LinkURL2'>Link2</A><BR></BODY></HTML>";
// Regex object to search
System.Text.RegularExpressions.Regex loCheck = null;

// search-string for regex (improtant: ignorecase-option)
loCheck = new System.Text.RegularExpressions.Regex("href=[\"']{0,1}([^\"'> ]*)", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
System.Text.RegularExpressions.MatchCollection loLinks = loCheck.Matches(lsCode);

// write every value in the list
foreach (System.Text.RegularExpressions.Match loResult in loLinks)
{
// loResult.Groups[0].Value = "HREF='LinkURL1"
// loResult.Groups[1].Value = "LinkURL1"
listBox1.Items.Add(loResult.Groups[1].Value.ToString());
}

// search-string for regex (improtant: ignorecase-option)
loCheck = new System.Text.RegularExpressions.Regex("[\"']>{0,1}>([^<]*)</A>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
System.Text.RegularExpressions.MatchCollection loLinksText = loCheck.Matches(lsCode);

// write every value in the list
foreach (System.Text.RegularExpressions.Match loResult in loLinksText)
{
// loResult.Groups[0].Value = "'>Link1</A>"
// loResult.Groups[1].Value = "Link1"
listBox2.Items.Add(loResult.Groups[1].Value.ToString());
}

In listBox1, all Link addresses will be added. In listBox2, all link text (within <A HREF>???</A>) will be added.

Hallo C# Friends Wink | ;)

,

I've a problem and hope for help.

I've created an automation addin for excel with .Net 1.1. It works fine.

Now, the same addin should work with fw 2.0.

I created a new Project with vs2005 (Addin Project). Same settings like the old addin.

I installed the addin and want getting started. But the addin won't start. The Function OnConnect never get started.

Has anybody else the same Problem or can anybody give me help?

Thank for attention
Mario

Adding a macro to my Word doc from C#

Dear group:
I have this Marco witch I wanna run it from my C# App.

Sub Macro1()<br />
    If ActiveWindow.View.SplitSpecial <> wdPaneNone Then<br />
        ActiveWindow.Panes(2).Close<br />
    End If<br />
    If ActiveWindow.ActivePane.View.Type = wdNormalView Or ActiveWindow. _<br />
        ActivePane.View.Type = wdOutlineView Then<br />
        ActiveWindow.ActivePane.View.Type = wdPrintView<br />
    End If<br />
    ActiveWindow.ActivePane.View.SeekView = wdSeekCurrentPageHeader<br />
    Selection.TypeText Text:="<big>a header here</big>"<br />
    ActiveWindow.ActivePane.View.SeekView = wdSeekMainDocumentEnd Sub

This is what I did but got an error in *oWord.

oWord.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekCurrentPageHeader;<br />
*oWord.Selection.TypeText text = "<big>a header here</big>";<br />
oWord.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekMainDocument;

My goal is adding a Header with Dynamic Text.
Tnx in advance.

Always Smile | :)

Escape the quote using the \ escape character:

string x = "\"";

or use a @-quoted string and double quotes:

string x = @"""";

b { font-weight: normal; }

Hi!

In C# you cannot do that in that way, this is just possible in VB. But you can use excape sequences for that:

string x = "\"";

The Backslash shows the compiler: 'the next charcater is a control character and not an normal character!'.
Her are other Escape-sequences:

\n = new line
\r = carriage return
\t = tab stop

Yes, it's possible in C#. @-quoted strings in C# works just like strings in VB:

string x = @"""";

i tried that

if i want show it on screen,it's right.but i want search this in a richtextbox.
then it finds not " alone,it finds with "\".

Re: using &amp;quot; in a string variable

MarcelErz13-Dec-05 22:30

13-Dec-05 22:30

Sure! You shoq the compiler with the "\", that it is a special character. So, even in searching, you need to input a "\". Otherwise the compiler will not know if it is a " in a string or a " around a string.

The string x will contain one single character, the quotation mark.

If you have any trouble using it, you have to be using it the wrong way. How do you use it?

MTAThread and AllowDrop?

13-Dec-05 21:19

Hi
I use a COM object which needs that I set my Threading-Model to Multi-Threaded-Apartment (MTAThread). If I do not set it to MTAThread I get System.InteropServices.COMException when I call COM-Functions.

If I set it to MTAThread I get a 'System.InvalidOperationException:DragDrop registration failed' exception when opening a Windows-Form element with AllowDrop set to true.

Is it not possible to enable DragDrop in a Multi-Threaded-Apartment?

Thanks
Martin

Convert a String to Binary

I want to convert a string to its binary equivelancy. How might I go about doing this? This is what I have so far, but it doesnt work.

if(textBox1.Text.ToString() != "")<br />
{<br />
	int temp2;<br />
	string temp = textBox1.Text.ToString();<br />
	temp2 = Convert.ToInt32(temp,2);<br />
	textBox2.Text = temp2.ToString();<br />
}<br />
else<br />
{<br />
	textBox2.Text = "Please enter a String";<br />
}

I don;t think that this is actually what you are trying to do but your code is designed to convert a binary number into a base10 Integer

Is the text in the textbox1 actually a valid binary string of mumbers? - e.g., "1000111100010".

So if the value was as above you are trying to produce the the Int32 equiv of that Base 2 Binary Number: e.g.:

<br />
int temp2 = 0;<br />
			string temp ="1000111100010";<br />
			temp2 = Convert.ToInt32(temp,2);<br />
			MessageBox.Show(temp2.ToString	());<br />

Produces the output
4578 which is the integer equivilant of the binary number 1000111100010

Is that waht you're trying to do?

I want it so that the user enters any String like "Hello World" into textBox1.

Then it converts the string to its binary form, 100101010010110 (or whatever it may be)

Basically I want it the exact opposite way that Rowan just described.

Re: Convert a String to Binary

-Rowan-14-Dec-05 0:41

14-Dec-05 0:41

Well, that is possible - can I ask why you want to do this?

If it is unicode then every character represents atleast 8 digits in binary. So if the text is Hello World you will have a string 8 * Length("Hello Word") = 80 Characters long.

Each character can be represented as a number between 0 and 255. So what you have to do is convert each character of the string to its binary number and then append it to another string.

Without actually writing the code I guess it would go something like this:

<br />
string temp1 = "Hello World";<br />
			string output = "";<br />
			foreach (char x in temp1)<br />
				output += ConvertToBinary(x);<br />

I couldn't find a Convert to Binary Routine so you may have to write one yourself.

Good luck.
