Use DateTime.Parse() instead, it's easier.

There's also a website ( http://regexlib.com/default.aspx ) which I use a lot to get the currect regular expression for string evaluation. HUGE database also and lots of approaches for the same goal.

Set a registry key or value in the config file to tell you it's been run before.

But not a problem, where theres a will theres a way :->

hello,
I am using the webbrowser control with c#. The problem I am facing is with javascript popups. I want my browser to behave like IE and display popups and allow toggling location, directories etc display on or off depending on window.open parameters.
Can you give me any pointers as to how I should go about it? If I make the links open in a new instance of the browser, the session data in webpages will no longer be valid....

I am trying to create a collection of classes with similarly named functions but different functionality in a DLL.
How can I create an instance of an object at compile time and then assign it a class at run time so that the action can be changed based on a user variable and not an ugly case/switch structure?
|
|
|
|
|
An OO class structure seems the way to do this.

You could implement the State Pattern - it's often a good choice for replacing switch statements, especially if you have them in many methods.
There's an article here:
http://www.codeproject.com/useritems/StatePattern.asp[^]
Or google for "State Pattern".

Hi, Dear Respected Programmers
1) Kindly let me know, How my I find my any required word or sentense in

Thank you

you can use regular expressions to find text in teh richtextbox, and as the text is found, you can replace it with the desired text.

;PIf I have a form with 5 text boxes on it how to I return the text from the active text box so I can copy it to a string or if the cursor is in a text box how can I paste from the clipboard to the active text box? All examples are very simple in that they all paste to or copy from textbox1 only. I was going to use these but can't figure out how to get the active textbox.
private void CutCopyData()
{
String str1 = null;
Clipboard.SetDataObject(str1);
}
private void PasteData()
{
IDataObject iData = Clipboard.GetDataObject();
//Determine whether the data is in a format you can use.
if (iData.GetDataPresent(DataFormats.Text))
{
string str = (String)iData.GetData(DataFormats.Text);
Thanks Jon Stroh

hi all,
I am able to highlight the syntax when I type the text ie c# code in richtextbox using the following code
code:
// Calculate the starting position of the current line.
int start = 0, end = 0;
for (start = richTextBox1.SelectionStart - 1; start > 0; start--)
{
if (richTextBox1.Text[start] == '\n')
{
start++;
break;
}
}
// Calculate the end position of the current line.
for (end = richTextBox1.SelectionStart; end < richTextBox1.Text.Length; end++)
{
if (richTextBox1.Text[end] == '\n')
break;
}
// Extract the current line that is being edited.
String line = richTextBox1.Text.Substring(start, end - start);
// Backup the users current selection point.
int selectionStart = richTextBox1.SelectionStart;
int selectionLength = richTextBox1.SelectionLength;
// Split the line into tokens.
Regex r = new Regex("([ \\t{}();])");
string [] tokens = r.Split(line);
int index = start;
foreach (string token in tokens) {
// Set the token's default color and font.
richTextBox1.SelectionStart = index;
richTextBox1.SelectionLength = token.Length;
richTextBox1.SelectionColor = Color.Black;
richTextBox1.SelectionFont = new Font("Courier New", 10, FontStyle.Regular);
// Check whether the token is a keyword.
String [] keywords = {"abstract","base","bool","break","byte","case","catch",,...."using","virtual","void" };
for (int i = 0; i < keywords.Length; i++)
{
if (keywords[i] == token)
{
// Apply alternative color and font to highlight keyword.
richTextBox1.SelectionColor = Color.Blue;
richTextBox1.SelectionFont = new Font("Courier New", 10, FontStyle.Bold);
break;
}
}
index += token.Length;
}
// Restore the users current selection point.
richTextBox1.SelectionStart = selectionStart;
richTextBox1.SelectionLength = selectionLength;
But my aim is to write c# code in text file and load that text file into a richtextbox and as soon as i load the text file into richtextbox the syntax should be highlighted.but in my case i am not getting that.
can anyone help me to solve this problem
Don't wait to hear a word of thanks from anybody when you help them instead ask them to help three other people and ask them to continue in chain.

Hi,
I want to manipulate an ACPI-device via C#/.NET . Having searched the net for a while now, I've been pointed to the System.Management namespace, but I can't find anything useful, I have no experience working with WMI and that namespace.
The goal is pretty simple: I have a laptop with a led, which should be displaying incoming emails. Only that it doesn't work with my current mail program out-of-the-box and the available plugins/addons/etc can't please me. Plus, I'm always into trying something new. So I wanted to write a app, which is independent from my mail-program and checks for mails, then flashes the LED, whenever there's new mail.
Could someone point me to some documentation on that topic (preferred also referring to .NET, examples/code would be great!)?
And just to be complete: The hardware is an ASUS laptop and the name of the "device" (the LED) I want to switch is "/_SB/ATKD/MLED", if that helps in giving me some hints.
Thanks in advance...

Hi
I get a web page with boxes (choices) that need to be clicked. I want to click a predetermined box when it comes in. That box may or may not be available or becomes available by changing color. When the right color is present I need to click it.
I am new at C# but I only what examples of how it might be done or at least pointed in the right direction.
I have downloaded the 1 example of an autoclicker that is here. Will investigate.
Thank you for any help you may give.

Then your odds of achieving this are low. Where is the web page coming from ? How do you hope to know what it's color is ( the most likely way is a complex HTML parser, or a screen capture ) ?
