You can use snippets or modify the new class template.

Thank you Chritian Graus.
Using the Export Template, I was able to export the template for the whole class which will surely be useful when I am writing a new class. But there are some existing class which I need to adhere to the coding standards.

This is what I want to achieve.
Open a file, Select a function, click the add-in/macro and a fucntion header in the form of XML comments should get added automatically. How can I do this?

Thanks and Regards,

Have you looked at GhostDoc.

It will do some of what you want if I understand you correctly. For a file header, you could try writing a code snippet.

Hi!
i want to close windows form when i click on any tree node. when i click a tree node, after_select event of tree node is called and in that After_select event i closed my current web form and opened new form but it throws following exception.

Disposed object of tree view could not be found.

I posted this question two times before also but no satisfactory answer is given. One of member suggested to use IDisposal but i m not getting how to use it. So, can anyone suggest me the solution in detailed form.

Thanx

IDisposable won't help here, the issue is precisely that you close the form while some code is running, and so the control is disposed while you're trying to use it.

You're closing web forms ? Not windows forms ?

private void TreeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
Form2 f=new Form2();
f.show();
this.close();
}

I do not know the exact solution:

But, see if this helps U.

Locate the line "Application.Run(new Form1());"
and enclose it within try catch.

try
{
Application.Run(new Form1());
}
catch(Exception exe)
{
}

Gosh - it's pretty obvious what's going wrong.

OK, I remember this. I told you days ago what to do.

You can't do this. Because, when you close this form, you cause the Form2 instance to also be closed/disposed. Instead, make form1 and form2 user controls, put them both on the one form, and switch between them.

Also, for goodness sakes, use real variable names and not TreeView1 and Form2.

That's not a link.

What the page you hoped to link to says does not matter. What you're doing is wrong. Create user controls, lay them out to be your two forms. Put them both on the one form, and then make only one of them visible at a time.

You are creating this object within the original form (where the TreeView1 is)... it is available only within the After_Select event. When you close a form, all objects that are part of that form are destroyed and references to those will no longer be valid.

Hope this helps.

Hi guys ,
I came across a piece of code similar to the below one.

public partial class Form1 : Form
{
private void Form1_Load(object sender, EventArgs e)
{
ad test = new ad();
Ia id5 = test.testobj();
id5.display()
}
}

public interface Ia
{
void display();
}
public class b : Ia
{
public void display()
{
MessageBox.Show("do it man");
}
}

public class ad
{
public Ia testobj()
{
b gh = new b();
return gh;

}
}

My question is why should we typecast object gh to interface Ia in testobj() function as the interface object when we can directly use the object of class b to call display function.

Thans in advance,
sishya

Because the point of an interface is that lots of objects can impliment it, and, despite their differences, they can exist as an instance of that interface via the same collection, or variable.

In this example, it is not necessary since the example doesn't do anything much. The reason to do so would be if other classes implemented the interface and you want to call display() for a collection of different classes using a common variable of type Ia.

Webbased SQL Query Analyzer?

Succodimele26-Apr-07 23:37

26-Apr-07 23:37

Hello I've got a problem.

In my office, the Port 1435 and 1433 under which my MSSQL Database runs is locked. But I have to use the db for the finish work of my apprentice. Is there something Like a Web based Sql Query Analyzer, where I can run SQL Code? With it I can generate my Stored Procedures and tables?

Best regards
succo

How does this relate to C# ?

You want to go to a website, which creates procs and tables on your local SQL Server, or which hosts one you can play with ?

I search a Web Application, which i can use on my ASP.NET web space. (Something like that: http://www.codeproject.com/aspnet/WebSqlUtility.asp) The Application doesn't have to have an intelligent. I Program my Application on my local Computer and when I'm finish i will put it online. I will create script, which creates the SPs and Tables. The tool have only to exec the SQL-Code.

You didn't answer me - where would the database be, local to you, or local to the tool ?
