It's been a long time since I've done any winforms, but in principal I'd:
- Extract the UI that allows viewing/adding/updating the record as a control.
- Set the control from above's enabled state to false - this will disable the control
- Show/hide buttons in the control as appropriate
Another option is to create two controls - one for add/edit the other for view only and display the relevant one. Depending on what you are doing, you can usually improve the user experience, though at the cost of extra work, so you need to balance these off with eachother.

If you only "SELECT" data it will always be readonly. Simply don't update the data.
No, MySQL has no magic functions.

how to create continue rotational word

A standard textbox automatically rotates a word throught 360 degrees - it's just to fast for you to see, as rotating something 360 degrees brings it back to its start position!

Sadly you see the result only, not the process...
Well, judging from your signature, you might see the process too, even if it is not visible to the rest of us.

The simplest solution is to just use a RichTextBox: add your RTF string to it; and, read back its 'Text Property:
YourRichTextBox.Rtf = YourRTFString;
string YourPlainText = YourRichTextBox.Text; Or, you could use this:
private char[] cleanRTF = new char[] {'\\', ' ', '{', '}', '\r', '\n'};
string[] sAry = str.Split(cleanRTF, StringSplitOptions.RemoveEmptyEntries);But, then, you've got to do something with the resulting string[], like combining it back into a continuous string, in which case you will still have lots of the RTF formatting codes.
For more sophisticated "cleaning" you should consider using a RegEx; but even that is not easy, as you can read about here: [^].

Am back again with another issue in my tool.
i need to grade out a text box, on selecting an option in a combo box drop down.
A part of my tool looks like this:
Label1 (Status) Combobox1 (In-progress, On-Hold,
Label2 (Result) Combobox2 (Pass, Fail)
i need the Combobox2 need to be Disabled only when i select "In-Progress or On-Hold" in the combo box1
i tried with implementing checkbox instead of combobox (if checkbox1.checked = true) etc. it works.
But i donot want to implement the same using combox box.
please assist.

And what is the problem?
You clearly know how to disable a Textbox, and you presumably know that the ComboBox has SelectionChanged events - so what part of this do you need help with?

Try this:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
comboBox2.Enabled = ! (comboBox1.SelectedItem == "In-progress" || comboBox1.SelectedItem == "On-Hold");
}Here the assumption is made that there are other selectable Items in comboBox1 which, if selected, should enable the use of comboBox2.

Hi all, I'm pretty new to C# and would like to have some questions answered regarding getting data from the user. Suppose I have a class called MyClass like the following:
Class MyClass
{
string firstName;
string lastName;
MyClass(string fName, string lName)
{
this.firstName=fName;
this.lastName=lname;
}
public string fN{ get { return firstName; }set { firstName= value; } }
public string lN { get { return _firstName; } set { lastName= value; }}
}
Then in the code behind of my aspx page I want to create an array of type MyClass and get firstName and lastName from the user and put them in the array.
I plan to have the user enter firstName and lastName into textboxes and insert them into the array by sending them in as parameters during the instantiation of the array. The following is what I have done but it does not work.
MyClass[] projects = new MyClass[4];
projects[0] = new Project(firstName, lastName);
Any help is greatly appreciated, thanks in advance

No, it won't work.
Or rather, it will - but not for long.
The problem is that you aren't thinking website - you are thinking desktop.
Websites do not work in the same way: the application is not running all the time, waiting for the user to do something. Instead, the website application is started again each time the user does something like request a page, press a button, and so forth. Which means that unlike a desktop application any data you assemble in your application ceases to exist as soon as the last bytes of data have going back to the client. If you don't store it somewhere permanent (or semi-permanent) explicitly, it is discarded, to make way for the next website / user combination.
If you want to keep a list of users, then you need to explicitly save the data, in a database, or in the Session, or in Cookies, depending on how permanent you need it to be.
