It's pretty straightforward. What do you do to calculate 25% ? You have the total, you just need to do the math to work out what 25 % is.
Alex501 wrote: const decimal TaxRate = 0.08M; // 5.75%
.08 is 8%, not 5.75% - the comment is wrong.
You calculate the tip exactly the same way that you calculated the tax.

You already got

so obviously you need to do the same but with the various tip percentages you mentioned

I am working on a printing a report and need to know how to calculate the font width by device. Height is easy (font.GetHeight(graphics);), but there is not a similar setting for width. There used to be an API call (I think it was something like GetTextMatrix) that I used to determine the average width (letters like M and W were wider than letters like I and l). Is there something I can do to check before I start printing? or is there a way that if I ireate through the arrays I can tell what the maximum width are for each column before I start the print page routine.
Thanks,

Use the graphics context for the device and call MeasureString.

I installed SQL Server 2005 in my machine couple of months ago now i dn't remember its password to login. Do i have to reinstall so i don't go through this hectic process.. Ya i am a local admin of my machine

SQL server 2005 had two login modes, "Windows Authentication mode" and "SQL Server and Windows Authentication mode". So that means that you should be able to log in with the Windows Credentials for the user you installed with. Try that and see what you come up with.

1) This is not the appropriate forum, the SQL or even General forum would be better than C# for this question
2) DON'T use urgent in the subject. It may be urgent to you, but not to everyone else. People volunteer to answer questions, saying urgent is like demanding a response. It's rude!

I want to compare between two dates.
One date is System Date mm/dd/yyyy format
Other one is User i/p Date in SAME FORMAT.
I want to check whether the User I/P date is greater/less/euqal than the system date.
How can I compare between them
|
|
|
|
|
I don't know what you mean by:
simworld wrote: Other one is User i/p Date
Anyway, you can compare dates as following
myDate1 > myDate2 or myDate1 <= myDate2, etc
|
|
|
|
|
I want to say..
I have a table that contains columns with date value(System date).
In a form a Text box (User i/p)that takes only date in a mm/dd/yyyy format
if user date will be greater/less/equal than the system date,then certain event will occur.
I want the C# code syntax that will compare those date.
i think this give u clear view what my question is??

The date comparison examples I gave before would be how you compare dates.
I'm guessing what you mean is that you want to make sure that the user enters a valid date and compare that to another date.
To do this you can implement code similar to this:
DateTime systemDate = DateTime.Today;<br />
DateTime userInputDate;<br />
bool bValidDate = DateTime.TryParse(textBox.Text, out userInputDate);<br />
if (!bValidDate)<br />
{<br />
MessageBox.Show(textBox.Text + " is not a valid date!");<br />
}<br />
else<br />
{<br />
if (systemDate < userInputDate)<br />
{<br />
}<br />
}

Use a DateTimePicker, not a TextBox.
|
|
|
|
|
Convert userIPDate to DateTime
DateTime DateNow = DateTime.Now.Date;
return DateNow.CompareTo(userIPDate); will return -1 if DateNow is less than, 1 if greater than and 0 if equal to.
|
|
|
|
|
The best way I have found is to subtract one DateTime from another, creating a TimeSpan object. Then use the result of the TimeSpan object to do your testing. Hope this helps!
DateTime dt1 = DateTime.Now;
DateTime dt2 = DateTime.Now.AddDays(1);
//Compare
TimeSpan ts = dt1 - dt2;
if (ts.TotalMinutes < 50)
{
//do good stuff here
}

You can't, not trivially. The backup format is supported by SQL Server, there's no methods you can call to unpack it, unless it's really a zip, or unless you can control SQL Server to do it via interop.

How can i read properties of a file(microsoft office) using ifilter. I can read the text in file as there are lot of such examples but no examples where i could read property( which are on summary tab of file property) using only c# any help will be highly appreciated

Try this[^] article form information on using IFilter. While he doesn't deal in the article specifically with summary info, it's fairly easy to then follow this up with a read of this[^] article which should give you more detail.
