The FolderBrowserDialog has a property called SelectedPath that gives you the path selected by the user. Use this path together with the classes provided by the System.IO namespace to get further information about the selected directory and its content. For example, to get the names of the files in the directory pass the return value of FolderBrowserDialog.SelectedPath to the static Directory.GetFiles method.

i want to create the list box which has horizantle and vertical scroll bar in asp.net using c#
|
|
|
|
|
Ask it in the ASP.NET forum.
|
|
|
|
|
I am not sure. Try applying CSS
|
|
|
|
|
private class classStr {
public string str;
}
public void temp()
{
classStr[] objStr = new classStr[3];
objStr[0].str = "New string";
}
when i m trying to execute above code it gives error at this line
objStr[0].str = "New string";
whether i hav to type cast "New string".
error generated: Object reference not set to an instance of an object.

Hi
You need to create an instance for each index of an array before accessing it.
Here is an example:
classStr[] objStr = new classStr[10];
for (int i = 0; i < 10; i++)
{
objStr[i] = new classStr();
objStr[i].Var = "New String";
}
Hope this is clear.

You must get that error!!!
Explanation: In the function temp,
In Line 1.You are creating an array of 3 elements. So that you are allowed to store 3 objects. But remember you dont have any objects so far in any of your array position(cell).
In Line2: The first object in 0th cell of the array you are trying to access( So far you dont hav anything in 0th cell of the array and so you get the error.)
So the bottom line is .... you must assign ( or store )something in the array before accessing array element(s).
Hope this helps ... 
Thanks,

What is the use or writting same code there ? When user clicks windows close button form will close automatically ? Then what's u r prob ?

Never mind. I got it. Its not as simple as it looks to be.
I wanted to delete all databases created in the project.
Earlier, a separate button used to do the trick.
But if the user fails to click the special button, then the databases wont be deleted, which will in turn pose a problem the next time i run it.
What I mean to say is before the application exits, a series of tasks/events should occur. With the windows default close button, the application simply exists. Hence I wanted to place the code of events over there.
anyways thanks.

Form.Close();
this.WindowState = FormWindowState.Maximized;
this.WindowState = FormWindowState.Minimized;

thanks got it.
I wanted a series of events to happen when the user clicks the default close button.
We can directly use the form closing event to do the trick.

You are not initializing array try something like
public static Form[] listFormChoose = new Form[4];

Thank you, but when I rewrite follow you, has a error :Index was outside the bounds of the array. Can you help me!

This means that the values of i and j that are used as array indexes are getting to big. Arrays have a null-based index, so if your array has four elements those are accessible via indexes 0, 1, 2 and 3.

I've been making a calculator that i can include in apps that may need one (for convenience)
But ive come accross a slight problem. I have it in hex mode, i type in FF, i use the not operator, i get FFFFFFFFFFFFF00. So all is good.
I do this by converting the hex FF, into a ulong (or UInt64). But when i try to use the NOT again, it goes to FFFFFFFFFFFFFFFF, this is because:
FFFFFFFFFFFFF00 = 18446744073709551360
and NOT 18446744073709551360 = -18446744073709551361
See nows there's the problem, ulong has no negatives. And im way to tired to think anymore. So any unput would be real good. Thanks.
