Hi,
I have just finished an article on timers, I trust it may well solve your problem.
I expect it will appear on CP in a matter of days.

Hi,
this dialog seems very good, but is there a way to make it run under .NET 1.1? Or in other words, what makes it only compatible for 2.0?

Oops, I must have posted my question in the wrong forum, but perhaps someone here can also help me with that. I mean the OpenDialogEx:
http://www.codeproject.com/cs/miscctrl/OpenFileDialogEx.asp
(I clicked "New Message" on the bottom of that page, now I am confused (about this forum), and there might be a cross-post somewhere else here...  )

Hi,
I have a WinForm that needs to run only if a registry entry exists. If not, I want the application to immediately exit.
I don't believe you can call Application.Exit until after initialization of the form is complete.
Is there a workaround or better solution to achieve my needs?

Why not do it in Form's Constructor.... It's run b4 Initialization. You can call dispose from there.
Or even better you can use a static constructor try to set a static boolean variable and check it's value b4 instantiating...
Any Static Construct is the first thing which is run After class loading.

Thanks for your assistance ... I have a rough idea of what you suggest but would appreciate your elaborating a bit.
This is what I have now:
<br />
<br />
namespace blahblah<br />
{<br />
public partial class MainForm : Form<br />
{<br />
public MainForm()<br />
{<br />
bool startupCheckValue = true;<br />
startupCheckValue = startupCheck();<br />
if (!startupCheckValue)<br />
{<br />
Dispose();<br />
this.Close();<br />
Application.Exit();
}<br />
etc etc etc<br />
<br />
private bool startupCheck()<br />
{<br />
[code works fine]<br />
}<br />
<br />
<br />
How do I go about implementing what you suggest.
Thanks in advance.

Thanks for that - I have since done some research and certainly understand constructors and specifically static constructors and methods a little better Frankly, I agree your suggestion should work - at least in theory.
Unfortunately I still can't get the program to exit. I made the changes you suggested without success and then as an extreme test changed it to the following:
<br />
public partial class MainForm : Form<br />
{<br />
static MainForm()<br />
{<br />
Application.Exit();<br />
}<br />
public MainForm()<br />
{<br />
<br />
[etc etc]<br />
I'll keep delving into this and welcome any other suggestions.

Application.Exit will nit work inside the constructor, because Application.Run wasn't executed yet. If you look at the static Main method of your application it looks similar to this:
static void Main()
{
Applivation.Run(new MainForm());
}
So what happens, is that an instance of the MainForm class is created (calling your constructor) and afterwards passed to the Application.Run method. That's why Application.Exit does not work inside the constructor.
It would probably be the best to assign the instance of MainForm to a variable and only call Application.Run, if your MainForm could be properly initialized:
static void Main()
{
MainForm form = new MainForm();
if (something)
{
Applivation.Run(form);
}
else
{
Show some kind of error message
}
}

i want to make my event in win form
using c#.i have created it but
the problem is that the event is not firing.
so i need your help.
i created these events by taking help of
vb.net program.
ashu

|
|
What event? and give us some code
|
|
|
|
|
What do you mean by not Firing... It's not meant to fire auto... You are required to do it explicitly.
|
|
|
|
|
You need to explain what you mean by 'not firing', and you need to explain how your code is working between VB and C#, probably by posting some code.

Hi! I am new to C# programming and have run into a roadblock. I don't know how to get it to count the number of months needed to pay off the loan. Here is what I have so far:
//declare variables
double loanAmount;
double interestRate;
double monthlyPayment;
double balance;
double monthlyPrincipalPayment;
int monthCounter;
double totalInterestPaid;
//initialize variables
loanAmount = 0;
interestRate = 0;
monthlyPayment = 0;
balance = 0;
monthlyPrincipalPayment = 0;
monthCounter = 0;
totalInterestPaid = 0;
//input statements
Console.WriteLine("Enter loan amount: ", loanAmount);
loanAmount = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("Enter monthly interest rate in decimal format: ", interestRate);
interestRate = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("Enter monthly payment: ", monthlyPayment);
monthlyPayment = Convert.ToDouble(Console.ReadLine());
//calculate monthly principal payment
monthlyPrincipalPayment = balance - (interestRate * loanAmount);
//calculate the total interest paid
totalInterestPaid = totalInterestPaid + (loanAmount * interestRate);
//calculate the total number of months to pay off interest
//while loop
while (balance > 0)
{
//count the number of months
monthCounter++;
//calculate balance each month
balance = balance - monthlyPayment;
}
//display the total interest paid
Console.WriteLine("You paid $ " + totalInterestPaid + " in interest");
//display the total number of months it took to pay loan
Console.WriteLine("It took " + monthCounter + " months to pay off your loan.");

Hi,
Your logic is flawed? You cannot calculate the interest on the whole of the loan unless you know how long they want the loan for. Therefor your program, as it is written, will go into an infinite logical loop as the balance will never be paid.
You will need to decide when you are going to calculate and charge interest. It seems the following is what you are suggesting:
Initial Loan $10,000 (for example)
Interest rate is fixed.
Interest is charged on daily outstanding balance and is included in the fixed repayment offered.
Repayments will be fixed each month (be careful here as you will create another infinite loop if the payment is insufficient to cover principal and interest).
psuedocode is:
While (BalanceOutstanding > 0)
{
count++; // whatever your counter is
BalanceOutstanding = (BalanceOutstanding * Rate / 12) - Payment; // psuedocode
}
You would be better of not using a While statement to calculate the months - use maths (used to be called algebra when I went to school ). Google for the appropriate formulae.
Cheers,
Glen Harvy

The problem is I am supposed to use the while loop to decrease the loan amount until it gets to 0. Thanks for your help.
