I used to use subversion (I used TortoiseSVN), but recently switched to Mercurial distributed version control software. There have been a few threads about it here in the lounge this past week. On windows, I am using TortoiseHg and on Linux, I am just using the command line. I am liking it very much.

Well, there are hundreds out there. If you are coming from a background of something like SourceSafe, then Subversion will come as a bit of a shock, because it has a very different approach to source control, but it's good once you get into its mindset. SourceGear's Vault is sort of "SourceSafe on steroids", GIT is very fashionable at the moment but I've never seen the appeal; same thing with Bazaar which is popular with some people (Pythonistas, mainly). MKS do some good products, but they are top-end and relatively expensive. There's also a freebie opensource Java one called SourceJammer which is probably OK for entry-level Java shops. Those are the ones I've had experience with (to varying degrees).

application Getting Crashed if i run the below code....

class Program
{
static void Main(string[] args)
{
try
{
Microsoft.Office.Interop.Word.ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
object file = "D\\two.doc";
object readOnly = false;
object isVisible = true;
object o_null = System.Reflection.Missing.Value;

Microsoft.Office.Interop.Word.Document doc = wordApp.Documents.Open(ref file,
ref o_null, ref o_null, ref o_null, ref o_null, ref o_null,
ref o_null, ref o_null, ref o_null, ref o_null, ref o_null,
ref o_null, ref o_null, ref o_null, ref o_null, ref o_null);

doc.ActiveWindow.Selection.WholeStory();
doc.ActiveWindow.Selection.Copy();
IDataObject data = Clipboard.GetDataObject();
string allText = data.GetData(DataFormats.Text).ToString();
//doc.Close(ref missing, ref missing, ref missing);
//wordApp.Quit(ref missing, ref missing, ref missing);
Console.WriteLine(allText);
}
catch(Exception e)
{
Console.Write(e);
}

}
}

can some body help me out and suggest me the actual problem or else correct it.

Thanks in advance....

First of all, please wrap your source code in PRE tags to make it easier to read.

Anyway, it seems like you're missing a colon here:

object file = "D\\two.doc";

It should be:

object file = "D:\\two.doc";

(I might be wrong, but that's the only explanation I can come up with)

Hello friends!
How to clear a text file from my code?
I write on C #.

an existing file can be:
- deleted with File.Delete(path)
- replaced by an empty file with File.WriteAllText(path, "")
provided the file isn't open and access rights allow you to do those things.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

Here are two ways you can do that:

C#

File.WriteAllText(@"C:\mytextfile.txt", string.Empty);
((new FileInfo(@"C:\mytextfile.txt")).Open(FileMode.Truncate)).Close();

If you meant you want to delete a file, you can do this:

C#

File.Delete(@"C:\mytextfile.txt");

See here[^]. This link give you an idea on how to do basic IO operations on a text file. You can open a file and clear its contents using these IO functions.

Hi,

I have to different type of lists.
List<firstclass>
List<secondclass>

i'm trying to add to the List<SecondClass> the List<FirstClass>

 List<SecondClass> secondClass = new List<SecondClass>();<br />
//query.ToList() => the list that returns by link with the type of FirstClass<br />
<br />
            foreach (FirstClass item in query.ToList())<br />
            {<br />
<br />
                secondClass.Add(item);<br />
            }

What i need to do to be able to add FirstClass items to SecondClass list?
Can someone please help me?

Make sure FirstClass derives from SecondClass.

List<T> is meant to contain only items of type T or a derivative of T.
Just like an array of int is meant to contain only int values.
That is the whole purpose of generics.

If you need a list to hold all kinds of objects, you have to find a common type T.
In the extreme, you'd have List<T> which is very much like the old ArrayList. But then you loose all the advantages of generics.

I understand.

Can i convert it to SecondClass [] instead of List<secondclass>?

what are you rambling about?
- changing a List<SecondClass> to a SecondClass[] array will not change the ability to "add" items of another type.
- turning a List into an array is what List<T>.ToArray() does.

I strongly recommend you read up on arrays and generic collections. Buy and study a book on C#. And use the MSDN documentation. And learn to use Google.

See? It *is* worse.

That has the same exact issue as List<SecondClass>. All generic collections would have this issue.

Not really. If you just create a List<object>, that will work too... or if both classes derive from some other common type, that'd work too.

[Forum Guidelines]

Create a base class (let's call it "MyBaseClass") from which to derive FirstClass and SecondClass.

At that point, you can create

List<MyBaseClass> myList = new List<MyBaseClass>();

and then you can add any object derived from MyBaseClass to myList.

If you want to know how/why this works, use google.

Hi My friends,

When you have a tabcontrol with some tabpages, how can browse tabpages automatically.
For example you located in tabpage3 and you need to go to tabpage4 after clicking a button.

Best Regards,
Reza Shojaee

Hi,

use TabControl.SelectedTab or TabControl.SelectedIndex. It is all documented.

Smile | :)

Harumph... That's the same as saying "use google". Smile | :)

Not really, there is no problem in locating the information. The only problem seems to be lack of willingness to read it.
