You mean is opened in Word of Excel, etc?
If so, one solution would be to wait until the file has been sent to the printer(by periodically checking the number of print jobs) and after that close the main application.
The first part can be achieved with this(code suggested by Martin#):
ObjectQuery qry = new ObjectQuery("SELECT * FROM Win32_PrintJob");<br />
ManagementObjectSearcher srchr = new ManagementObjectSearcher(qry);<br />
ManagementObjectCollection coll = srchr.Get();<br />
<br />
int initialJobs = coll.Count;<br />
<br />
while (coll.Count == initialJobs)<br />
{<br />
System.Threading.Thread.Sleep(10);<br />
coll = srchr.Get();<br />
}
Good luck!

Hi,
I need to compare the records between two datasets, having 5 columns in each.
Dataset1 contains 5 records and Dataset2 contains 100 records.
I need to check whether all the records in dataset1 is present in dataset2 ,
and suppose if the records are not in dataset2 i need to check how many records are not present.
Can anyone help me..

Hi Jintal Patel,
I need to compare the complete row..
I need to find the exact row match.
currently i'm using a for loop
for eg
for(int i=0;i<dataset1.tables(0).rows.count;i++)
{
for(int j="0;j<dataset2.tables(0).rows.count;j++)
{
" <code="" to="" compare="" each="" column="">
if(dataset1.tables(0).rows[i].itemArray[0].tostring()==
dataset2.tables(0).rows[j].itemArray[0].tostring())
{
}
if(dataset1.tables(0).rows[i].itemArray[1].tostring()==
dataset2.tables(0).rows[j].itemArray[1].tostring())
{
}
}
}
Is thr any better way ?

="" for="" (int="" j="0;" <="" dataset2.tables[0].rows.count;="" j++)
="" {
="" for(int="" k="0;k">5;k++)
{
if(dataset1.tables(0).rows[i].itemArray[k].tostring()==dataset2.tables(0).rows[i].itemArray[k].tostring())
}
}
}
try this.

There is performance issue with for loop. So i need to know whether we have any inbuilt methods.

Have you try using Sql Query?or You don't want to slove using Sql Statement.

Tried to use the DataTable.Select(...) method?
DataSet ds1 = new DataSet(), ds2 = new DataSet();
DataTable t1 = ds1.Tables.Add();
DataTable t2 = ds2.Tables.Add();
for (int i = 1; i <= 2; i++) {
t1.Columns.Add("C" + i.ToString(), typeof(int));
t2.Columns.Add("C" + i.ToString(), typeof(int));
}
for (int i = 0; i <= 5; i++) {
t1.Rows.Add(new object[] { i, i});
}
for (int i = 0; i <= 100; i++) {
t2.Rows.Add(new object[] { i, i });
}
for (int i = 0; i < 5; i++) {
DataRow[] good = t2.Select("(C1 = '" + t1.Rows[i][0].ToString() + "') AND (C2 = '" + t1.Rows[i][1].ToString() + "')");
if (good.Length > 0) {
}
}

Hello Everyone,
Can anybody tell me wht's the diff. between virtual function and new modifier in C#
|
|
|
|
|
Virtual functions
When you have a function defined in a class which you want to allow to be implemented by the inherited classes you can use virtual function.
The virtual function could be implemented by the inherited classes in their own way and the call to the method is decided at runtime.
New Modifier
The new modifier creates the New instance(object) of the class

No it doesn't. The new modifier tells the compiler that a method ina derived class is a new implementation and the compiler should hide one of the same name / signature in a base class.
The new operator creates new instances.

So why
class A
{
public void SomeMethod()
{
Console.WriteLine("Base called");
}
}
class B : A
{
public new void SomeMethod()
{
Console.WriteLine("New called");
}
}
public static void Main()
{
A instance = new B();
if (instance is B)
instance.SomeMethod();
RL();
}
writes "Base called" on the console??
Nb. if A.SomeMethod would be virtual and overriden in B , then "New called" would be displayed.

Exactly - it is virtual, so the overridden method would be called.
gajatko wrote: public new void SomeMethod()
In class B, you have modified the method as 'new', which removes any inheritance of that method. Type A has no knowledge what so ever of this method now.
gajatko wrote: A instance = new B();
You instantiate a static member of type A with a dynamic instance of type B. Calling the method on this instance will invoke the Type A method, as that is the only method matching the signature, and it has not been overriden.
( I think...!! )

The first thing you should learn as NIIT is www.google.com. Just out of a bizarre curiosity, I typed both your questions into google, exactly as you typed them here....and guess what....
MP3 - 850,000 hits...hmmm[^]
Txt - 956,000 hits....[^]
Now, as a student, what do you reckon is the better way of getting an answer to these questions? Google, getting nearly 2million responses in less than 0.5 seconds or posting the question here and getting nob all except sarcasm and stupid replies as you are too lazy to even search for this yourself?

Why?
OK - you ask on code project. You get maybe 1 or 2 answers. They could be similar, they could be different. YOu look on google, you get a million answers. You look at three or four, or more (there's plenty of them) and you then get a feel for the correct way to do something.
Why I think you want an answer here : It is so you can cut and paste the code, verbatim, without having to understand it, and when you find you can't even do that you have the person who answered your question on hand to guide you through it step by step.
Good luck Sir.

You can still use Google to search CodeProject.com. Just suffix
site:codeproject.com to your search query string and Google will restrict the results from CodeProject.com.

Codeproject memebers will help you with stuff that you have problems with. In this case it seems you have a problem with using google and a codeproject member helped you!
Don't expect people to come running to help you if the answer can be found in a few seconds on google, that just makes you look lazy.

you were helped. you didn't tell us you had a problem. you only wanted us to tell you how to do it. Have a go first, when you hit a problem, then ask for help - I will guarantee you will get help then. Don't go off all grumpy because because you asked the wrong question....google for it, have a go, and see the difference a bit of effort makes.;)

You are unbelievable. Search for it yourself. If you have a problem with the code, ask about the problem. Don't ask for a general solution to your requirements.
