}
conn.Close();
}
i m opening this form 'Login' on button click n then if i close this form by clicking on close button, application itself must also stop running automatically. As even if i close all forms the application keeps on running till i stop it myself.
Plz help on it.
Thank You.

You have to set up an event handler for the Form.Closed or Form.Closing events then handle your application exiting functionality there. However you're going to want to probably inherit the form class into a new loginform class so that you know the internal state of the login form so you will know if the form window is closing because the [X] was pressed, or because the login process completed and it's time to move onto different things, without exiting the application.

first remove this
If (login_.Close()) Then
{
Application.Exit();
}
one prob solve.
|
|
|
|
|
but after i logout, this login form is shown again, now if i close this login form from close button, application must also end automatically,which is not ending till i stop it myself.
how to do it?

Arey, 'close' is not my button, it is the form close button on top right side with minimize n restore buttons.
|
|
|
|
|
Private Sub formName_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Application.Exit();
End Sub
this is the even of form this is called at the time of form closing. ok
and formName is the name of form.

thanx, yes it is working.
take care. cu

You can't add the framework to your app, you need to deploy it seperatly.

Hi
Create two connection. First connection open sql server db and access in next con. Write a loop that fetches data from SQL server and inserts into access.

 I am just learning C#, and am having a problem with it that I don't know what I'm doing wrong with.
I have a method that asks for and recieves two numbers. These are parsed into two int's, and then stored. The next method is supposed to add the two numbers together, and give a return, i.e. sum. I also have outside the methods but inside the class "int firstNum, secondNum" declared.
When I try to call the method using;
DetermineNumberSum(firstNum, secondNum);
I am told that my firstNum and secondNum are errors because of "Use of unassigned local variable 'firstNum/secondNum".
I have not got a clue as to what is going on. Can anyone point me in the right direction so that I can solve this problem.
Thank you in advance for your input.

just Initialize like below.
firstNum =0,secondNum=0;
i hope it will work

I'm sorry, I think that I didn't express myself correctly. the two numbers are initialized by whatever the user puts into the the original string. The string is then parsed into an "int".
public static void fetchTwoNumbers(out int firstNum, out int secondNum)
{
Console.WriteLine("Type in the first number.");
string strFirst = Console.ReadLine();
firstNum = int.Parse(strFirst);
Console.WriteLine("Type in the second number:");
string strSecond = Console.ReadLine();
secondNum = int.Parse(strSecond);
}
As you can see some input is needed to initialize them.
Thank you though.

You are using the variables firstNum and secondNum, and have not assigned them a value. Local variables must have a value assigned to them before they can be used.
You said something receives two numbers and parses them into ints, I can only assume it looks like this:
Int32.Parse(strFirstNumber);<br />
Int32.Parse(strSecondNumber);
Well, when you do that you must not be storing those values into either firstNum or secondNum. So after declaring firstNum and secondNum, aka "int firstNum, secondNum;" you need to say something like:
firstNum = Int32.Parse(strFirstNumber);<br />
secondNum = Int32.Parse(strSecondNumber);
Then call:
DetermineNumberSum(firstNum, secondNum);

This is the coding I have at present. I think it is what you are saying.
public static void Main()
{
int firstNum, secondNum;
DetermineNumberSum(firstNum, secondNum);
fetchTwoNumbers(out firstNum, out secondNum);
}
public static void fetchTwoNumbers(out int firstNum, out int secondNum)
{
Console.WriteLine("Type in the first number:");
string strFirst = Console.ReadLine();
firstNum = int.Parse(strFirst);
Console.WriteLine("Type in the second number:");
string strSecond = Console.ReadLine();
secondNum = int.Parse(strSecond);
}
public static int DetermineNumberSum(int firstNum, int secondNum)
{
int numberSum;
int first = firstNum,
second = secondNum;
numberSum = first + second;
Console.WriteLine();
Console.WriteLine("The sum of the numbers is: {0}", numberSum);
return first + second;
}
It should work but, I am still getting the "Use of unassigned local variable 'firstNum/secondNum'. I don't know why. Thank you for your input though.

No, this cannot work. You need to assign values to firstNum and secondNum, OR use them as out parameters. You try to use them BEFORE using them as out parameters, and you didn't give them values to start with, which is always bad programming. You should also create one variable per line, for readability.

Using pdflib library in C# I have created a pdf file which is
protected using owner password .Different options are disallowed like
print, copy contents etc. Things were working very fine untill i came
to know about some password crackers which could easily crack the
file , eliminating the password , thus making it possible for
operations like printing, copy etc .
The study showed that using user password as well will make the file
strong enough to be decrypted ,but "user password" is not a solution
in my case .
The code which actually creates a pdf file using pdflib is as under :
PDFLib obj = new PDFLib();
obj.begin_document(FileName, "masterpassword=23wdlm3ldjwld4w
permission={noprint}");
Now i wonder even that the file is encrypted using 128-bit
encryption , how a password cracker can retrieve that stored password
form the encrypted file .What operation is performed by the cracker to
remove the password and making the file accessible for all options .
Can any one please help me in this ....
Regards,
Madni
