thanks for the help,
i change my code like this:
privateFonts.AddFontFile( @"c:\Windows\Fonts\XX.ttf");
but after i install my program i got message that can't find the file
|
|

|
|
OK, the thing to do is to NOT change the code. You should be diagnosing what the installer is doing with that font file. Find out first, then react to it.
|
|
|
|
|
Is the file actually there? If no, your installer is in error. If yes, you're probably passing another path.

thanks for the help,
after the install i see the font file in my application folder
but still same error.....
|
|
|
|
|
how do i make my program autorun when my computer open(windows service)?
|
|
|
|

Not enough information.
What is this program supposed to do? Does it require a user interface? Is it support to start doing it's processing when Windows starts, or when a user logs in?
Windows Service applications starts after Windows starts and do not show an interface at all. You'd have to write your application specifically as a Service application.

Create an application which will call the web services or do what ever you want...then make an exe..put that exe in C:\Users\arka\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup this location. As your computer will start your app within this path will execute.

That location doesn't start an app when Windows starts. That starts an app when that user logs in.

Some cleaning apps might flag it as possible malware though; the start-menu folder usually contains links to executables, not executables itself.

I was just reading someone's blog where he tested
bool isEmpty = (MyString == "");
bool isEmpty = string.IsNullOrEmpty(MyString);
bool isEmpty = string.IsNullOrWhiteSpace(MyString);
bool isEmpty = MyString.Equals("");
bool isEmpty = MyString.Length == 0;
and he listed the number of ticks each example took.
That got me thinking....
If you wanted to know of a string was null, that's one thing, and determining if its an empty string is another.
But do you REALLY care about TICKS???
With today's PC's and Servers running at ultra high speed, why would anyone really care?
Bonus question: I prefer IsNullOrWhiteSpace. What's your favorite & why?

Most of them are not even equivalent.. of course you can weigh both apples and oranges, but there aren't many useful conclusions that can be drawn from the results.Coder For Hire wrote: With today's PC's and Servers running at ultra high speed, why would anyone really care?
Moving into hypothetical territory here, it's easy to make up a scenario in which it matters. "Do that thing a billion times" is usually a good start.
By the way, if you're referring to this blog[^], then disregard the results, that's a very bad benchmark, he makes all the rookie mistakes.

I can identify these mistakes:
- he uses DateTime.Now instead of StopWatch
- he doesn't allow for JIT-precompilation
- no GC.Collect() (which shouldn't matter much here but would be good practice)
Are there more mistakes?

A couple more,
- the result goes nowhere. Apparently it worked, but it's dangerous (operation could be discarded, and really they should have been, so I have a sneaking suspicion it might have been run while suppressing JIT-optimization).
- the whole thing is only done once. The worst part of that is the JIT-compilation, but there is also "turbo lag" (part of the first loop could run at a lower frequency), other start-up nonsense (extra cache misses and so on), and a semi-random number of context switches.
- from these benchmarks, it's impossible to tell how much of the time taken is due to the loop overhead.
- it's measuring a throughput but kind of implying it's a latency.

Thank you, Harold! I got the first points but I don't see how he's implying that it's a latency - can you elaborate on that?

Well, he doesn't really come right out and say it, but the way he puts things makes it look like it's about latency. Things like "worth the extra ticks" or "takes x ticks", none of it is actually wrong but I just get that vague sense that he doesn't really make the distinctions between how long something takes and how often you can do it in a unit of time.

Ah, alright. I thought I should be able to see that in the code  Thank you, Harold.

string MyString = null;
bool isEmpty = (MyString == ""); What do you think the result of this little test is? (Slightly non-intuitive if you expect this to blow up because MyString is null).
string MyString = " ";
bool isEmpty = string.IsNullOrEmpty(MyString); Okay, is this an empty string? This is a common test to see if a user has entered some details - a space generally isn't considered true for entering details. We can dispense with the last two examples by using the same MyString = null assignment. Because it's null, neither will work so you'd have to issue a null check beforehand anyway.
By omission, you can guess which my favourite is.

I'm in the same camp.. I like IsNullOrEmpty because it's really all you need.

Ahem - my camp is strictly in the IsNullOrWhitespace field. I've pitched my tent, put on the gas stove and am boiling up a brew.

All are different functions but doing almost same work.So my choice better to use IsNullOrEmpty() as its safe and performance is good as compare to IsNullOrWhiteSpace().As IsNullOrWhiteSpace()can be removed if you are not using Unicode data.Apart from that other functions Equals and Length check functions having some performance issues in large projects.
So I prefer ISNullOrEmpty() in many situation.
At last its depend upopn the code what it needs.
Thanks.
