The result of integer division is always an integer; if you want a real (i.e. float or double) result, make sure at least one of the operands is real; for constants, append ".0" to the number, for variables use a float/double variable, or cast to float or double. Examples:

100.0/48
100/48.0
100/(double)INT48
((double)INT100)/48
DOUBLE100/48
100/DOUBLE48

Then optionally use formatting to get the number of decimals you want, as in x.ToString("N3"); or x.ToString("F3");

No offense but you really should have known that.

sure, using a language assumes such basic knowledge; however if he were an experienced VB programmer, things get confusing as division behaves somewhat differently in VB.

And how often do we see things questions like: why do I get zero from percent = current/maximum*100;?

Too often. But that's more of an operator precedence problem IMO

Not in VB, if you do

Dim a As Integer = 1 / 3 * 100

the result is 33 (unless you have Option Strict On, then it results in an error); in C-like languages 1 / 3 * 100 is zero.

Well VB is odd. I didn't know it was That odd, but then I'm not a VB programmer and I've never written a single line of VB Smile | :)

Uhm beginner coders are also allowed to ask questions aren't they?

Absolutely!

Your question was easy to understand, even if it appeared simple to some members. They forget that they didn't know things not so very long ago. Smile | :)

As long as you continue to post clearly defined questions, carry on doing so.

Bear in mind however that if you ask too many really simple questions, all you will get back is suggestions that you buy a beginners book. Which is not a bad idea. It gets you past the really simple stuff and using the IDE and so on, so you might consider that anyway.

[Edit]
It has been pointed out to me that it is not enough to just buy a beginners book. You have to read it as well and work through the examples it contains. Big Grin | :-D

doesn't help at all. You have to study the book; owning it and keeping it around for future reference is a good idea, however it isn't sufficient. Laugh | :laugh:

I think you are looking for some fuscator.
Please go through this first DotFuscator[^].

The link given by Arindam Sinha, is correct but you should be aware that you cannot currently hide your .Net code from a determined hacker. All that Obfuscators do is to slow them down a bit.

Every working executable can be cracked, all we can do is slowing things down. You can obfuscate with Dotfuscator or protect your executable with Themida.

I personally use DotFuscator.

64-bit Jet OLEDB Provider

I was using the Jet OLEDB Provider in my web site to convert SQL table to Excel sheet.
When I moved to 64-bit OS (IIS real 64 bit), it turned out that the Jet OLEDB DLL is not supported in 64-bit and Microsoft does intend to do so in the future - What options do I have to support this option (Saving SQL table to Excell file) in 64-bit OS?

Thanks

This is not a C# question as far as I can see. Please read How to get an answer to your question[^], and post in the correct forum.

You have no choice but to force your app to compile as 32-bit only. Look for "Target Type" or "Target CPU" in your project properties, probably behind an "Advanced" tab or button, and set it to "x86".
