I thought I'd made them. Put your database on the server, store your answers locally in an encrypted file, so if they alter the file, the server won't accept it. Send the answers to a web service when the app can find a connection. Accept that people who reverse engineer your code and create new encrypted files probably deserve to get good marks anyhow.

agreed.
but the problem is,
there are too many fields and too many things to take care of.
so using flat files will be a big head ache.
thats why we need database.
we have thaught about using files but concluded that we will need to use database.
whats ur view?

I think I've stated my views often enough. Anyone can read your code, a password is easily broken. In fact, almost anything you do, will be broken reasonably easily, but just a password, that will be trivial.

can i develop an application in -for example- VS2005 and run it over Linux, well i know about the mono-develop project!! but it's different from my requirement, am talking about full portability like in Java??
thanks in advance
Never stop learning!!

No, Mono is your only option.

well i have a related second question -maybe it's stupid one-, i understand that Sun made JVM -Java Virtual Machine- to support portability for all O/S, but what i don't understand why Microsoft used also a Virtual Machine while their .NET applications are going to run only over Windows

I have no idea, I suspect it has to do with MS regardig the other 3% of the market to not be their problem. MS have said people are free to develop versions for other OSs, but Mono is the only one that's come to light, so far.
Perhaps it also has to do with multi platform being why every Java GUI app is a nightmare. Perhaps MS just didn't want to go there. What .NET does is multi language to a common framework, not a common framework for many platforms ( although it CAN do that, too, if anyone wants to do it )

Well, he can code in VS2005 and just compile it with Mono - that's what I do. In many respects, Assemblies produced by MS's compiler are compatible with Mono too (you're asking for trouble if you execute them, missing dependencies, etc, etc, but you can probe them easily).

Hi.
I don't underestand what is delegate, and where is need !!
I'd read many papers ....
You know any refrence that describes it clearly ?
Best wishes

A delegate is a function pointer. An example of a delegate is a click event. If you place a button on your form class, that button defines a delegate, that is, a function signature. Your form class can subscribe to the delegate, that is, it can write a function with that signature, and tie it to the event. When your button class registers that it's been clicked, the code in your form class is called. so, delegates are a way for one class to call a method in another class.

A delegate is a something like int,string etc used for functions.
Basically a delegate declares a type for a specific function signature.
Then using this delegate you can create a function pointer.of coarse target function signature and the delegate's function signature must much.

So I want to poll for example if program is in "C:\prog1\" I want to put this path in string at program start up, so i can manipulate files accoring to that as root folder?
|
|
|
|
|
It actually happened to me few times some files ended who know where when I only set file names in program and no path... (all work fine with absolute path but I don't want to hard code it) so I want to prevent this behavior?
|
|
|
|
|
string originalPath =System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
will this work for you.
this gives full path of ur exe file u have to parse to get the path only.
|
|
|
|
|
Application.ExecutablePath, I believe. It's something like that.

Thank you both, I tried
Christian Graus wrote: Application.ExecutablePath,
and it work just fine, I'll try other method too.
Does anyone know maybe why XMLTextWriter write file who know where sometimes if only file name is specified (and it's almost random, sometimes it end up where it need to be)?
This way it work fine
|
|
|
|

If you don't specify a path, the working directory will be used. It's usually the same, but not always.

Yeah for example if array list is same on serialization like one I deserialized in (data didn't change) than it remain same, but if I added something to it... then it isn't go figure...
|
|
|
|
|
I use Application.StartupPath...
|
|
|
|
|
I'll try this also... although other solution work nice... but as they say there is always more than one way to do something in programming
|
|
|
|
|
Try Application.ExecutablePath
There is also and another property which return the applications folder. Sorry currently i don't have access to VS
|
|
|
|

kinda' late but maybe it will help ... Application.StartupPath

Thanks... it's not late all things I do in C# for now are only my learning so more I know better...
I'll implement all options to see if there is any difference...

I have a bitmap (300x471) which I added as a resource.
I wanted to modify the bitmap and display it.
My picture box control has also same dimensions. (300x471)
void Smile_Load(object sender, System.EventArgs e)
{
_Background = Book.CSharp.Properties.Resources.Monaliza;
_Final = new Bitmap(_Background.Width, _Background.Height);
Graphics fg = Graphics.FromImage(_Final);
fg.DrawImage(_Background, 0.0F, 0.0F);
fg.Dispose();
pictureBox1.Image = _Final;
}
problem: If I give picture box actual bitmap (pictureBox1.Image = Background) it fits inside the control.
But if just copy to new bitmap, then it does not fit and control scales to bigger bitmap and only show partially which is very annoying.
I looked different articles and it looks perhaps this is done by AutoScaleDimensions
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.None;
I played and also even removed, but no effect.
Any idea?
A prompt answer will be very appreciated.

Yep, I would suspect the automatic scaling.
Maybe you can replace
fg.DrawImage(_Background, 0.0F, 0.0F);
by
fg.DrawImageUnscaled(_Background, 0.0F, 0.0F);
FYI both also accept int coordinates, no need for floats here.
