I'm changing a control property at design time (backColor, etc), at some point of the program... I want to restore the control's default properties that I have chosen at design time.
Is that possible?

Hi, Im a first time poster long time user of the code project.
I am currently working on a web browser. I have release the beta 1 version (its called: T.I.B. [Beta 1])and people all over the place loved it especially the people that tested it at Cybershack Forums.
I am now making a beta 2 and i have failed many a time to figure out how to get the html source of a webpage to open in a notepad document (.txt) like Microsoft Internet Explorer or for it to open the html source in a richTextBox when the user wants to view the source.
Can somebody help me out here, can you make me a code that will open the html source from a web page in a web browser control that will open in a .txt document or in a richTextBox or even in a pop-up windows form.
P.S. If somebody does manage to help me out here, i will give them credit for their programming in the credits of the my web browser program as a sign of how grateful i am.

Why not combine these two? Create a windows form with a RichTextBox and assign the html source to its Text property.

You can invoke the View Source function in the AxWebBrowser object:
http://support.microsoft.com/?kbid=329014[^]
or you can do this your self by getting the source of the document, and writing it to a text file in your temp folder, then simply launch notepad with the filename as an parameter.

I still don't get it... perhaps somebody who gets it can make a demo project of this function, it would be good.

I am trying to write data to a textbox I have on a form (Form1) from a method in a class.
In my class I try writing -
public class NumberProcessing
{
public static void UpdateNumArray()
{
Form1.textBox1.text = "hello";
}
but the intellisense does not recognise anything past Form1.
Why can I only access textbox1 when in public partial class Form1 : Form ?
How can I access the textbox property of Form1 from other classes ?

Sorry, c# is not VB6 you need an object reference to Form1 in order to update it. If you insist on this pattern pass the reference to the form in the NumberProcessing contructor. However, I seriously recommend scrapping it and trying again. From what I see you are about to design something very unmaintainable.

Thanks for your reply. I am very new to C# coming from a C programming background.
I do not fully follow what you mean as I understand constructors to be used when creating an instance of a class (i.e an object) here I am using static type which can not be initialized. If possible could you give me a short example of what you mean?
Basically I want to know how I can get access to the textbox property from a class other than Form1?
Or do I / should I always make reference to to the textbox property from within the Form1 class?
Thanks in advance

class SomeLogicClass{
public static void DoSomething(Form form){
}
public static void DoSomething(Control control){
}
public static void RegisterForm(Form form){
}
}
Also, you can create a singleton class. There are a lot of options. However, the path you are taking I have seen before and it will cause problems in the future. Look for some samples in a c# book as a good guide.

Trying for a more helpful version of the comment you got...
haz13 wrote: Form1.textBox1.text = "hello";
Form1 is a class. You need to access an instance of the class to pass a value through. What you're trying to do is a VB6 hack.
The best way to do this is to create a delegate between the two classes. I assume delegates can be static, although I've never seen one. If not, you will need an instance of NumberProcessing inside Form1.
The other way to do it is to create a property on Form1 which sets the text of textbox1, and pass a reference to the Form1 instance that's in use to NumberProcessing. This is less of a hack than what you're doing, but not as nice as the delegate.
I trust the code you're showing is just pseudo code. There is no level on which textbox1 and form1 are acceptable variable names. Also, if your controls are public, change them to protected at least. That's just another poor design that you'll come to regret later.

Yes the use of delegates can do that,
Declare a delegate event handler, implement that event handler
in the Form1 class and invoke that event from the other class where you are trying to set the textbox value and pass the value as a parameter to the delegate.
e.g
public delegate void TextChangeEventHandler(string text);
public delegate void ChangeText;
Then implement this method :
You can just write
this.ChangeText += new TextChangeEventHandler(ChangeText);
then the method
Public void ChangeText(string Text)
{
textbox1.text = Text;
}
and in Your class u can just raise the event
Form1.TextChangeEvent obj = new ...
and obj.Invoke();
Hope that works for you

Thanks for your more helpful version. I am new to this oop and slowly getting my head around it.
I have gone away and read up on delegates but still fail to understand their use.
I understand what you mean in your second method but am slightly confused about loading a reference into my NumberProcessing class. Surely when creating the instance Form1 which is public(of the form class) Form1 properties and methods should be available to other classes within the same namespace. I don't understand why I can't see them?
OK - accepting you can't see the properties and methods of Form 1 in other classes, how do I load a reference of the Form1 object into my static NumberProcessing class?
Here is my code - the problem is when trying to access Form1.SetFormData(); in the NumberProcessing class.
namespace RouletteV1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btn1_Click(object sender, EventArgs e)
{
NumberAttributes.Load(1);
}
public void SetFormData()
{
//here is where I will set the textbox properties
textBox1.Text = "Hello";
}
}
}
--------------
namespace RouletteV1
{
public static class NumberAttributes
{
public void Load(short Number)
{
// load the number data into global properties here
NumberProcessing.UpdateNumArray();
}
}
---------------
namespace RouletteV1
{
public static class NumberProcessing
{
public void UpdateNumArray()
{
// Here I want to call the SetFormData()function in Form1 but it won't recognise it - why???
Form1.SetFormData();
}
}
}
Thanks in advance for your help - Please feel free to comment on what you think to the structure of the program - if you think I have made any other fundamental mistakes

Is it possible to copy a file using .NET where the path is greater than 248 characters? If not, are there any work arounds?
|
|
|
|
|
Before asking this question you should atleast try this I hope this will work.
Use File.Copy() Method
Best Regards,
Rizwan

|

This is what I use but my path contains more than 248 characters which throws a System.IO.PathTooLongException exception. I was wondering if there was any way around this.
|
|
|
|
|
Have you tried
FileInfo f = new FileInfo(LongPath);
f.CopyTo(NewLocation);
|
|
|
|
|
Yes - it throws the same exception.

Hi guys,
In my title bar title text I have my application name and then next to it I would like to put TM, in very small letters. How can I do that?
Please help

Open up Microsoft Word, Choose Insert --> Symbol.
Select the 'TM' symbol
Copy it
Paste it in the TEXT property of your form.
This is the 'non technical' way of doing it
