I hate repeating myself.
YOU have to tell us what the problem is. We're not going to copy and paste your code into a project just to diagnose whatever problem you're not telling us about. What problem are we looking for?
Just posting your code and saying "it won't work" will NOT get you a solution to the problem.
You also have to post in the correct forum. You're posting this question in the C# Forum. You want the Visual C++[^] Forum.

i hate repeating myself too. and yeah by the way where's the forum then if not here? i'm doing C Programming. and not Visual C++.******

Look at the top of any forum page. You'll find the link to Visual C++. Since C is just a subset of C++...

Dave is right, but in addition, did you mean to write a C program, or C++ ? This program is in C not C++. you can still ask in the C++ forum, of course.

Are you saying you need to know that the .NET runtime has to be installed on any machine so your code can run on it ? That's what's needed to ship your app.

SqlConnection con = new SqlConnection("server=SK-WAQAS;uid=sa;pwd=Butt;database=pubs");
SqlDataAdapter daemp = new SqlDataAdapter("Select * From employee where emp_id= '" + empid + "'", con);
DataSet ds = new DataSet();

What do you not understand? The compiler message is very clear: 'Underfined label 'main' in function main'
You're using a label called "main" in your function "main" and this label is not defined.
Most likely you've got a syntax error, but without even giving the full and correct error (the compiler didn't output "Underfined" for sure!) or the code line the error occurrs on you won't get any decisive help!

Hello,
I am wondering if anyone can point me in the direction of a nice bit of code to draw a tree structure. Not the tree that is one of the default windows controls, but the list tree structure

like that.
Thanks

How does one go about making part of the messagebox() show a web link?
something to the effect of:
MesageBox.Show("Help File Not Found: \n\nTo download the latest Helpfile, go here:" + SomeSortaWeblink(http://www.mysite.com))
Any help is truly Appreciated

You can't. You'd have to create your own dialog box that has a Link control in it.
Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

There is no direct solution to this.
What you can do is , write a Customized Message Box (your own Form) which can include this.

i need to serialize an object but before to serialize i want to encrypt it
How can i encrypt? Can someone decrypt it with some program?
|
|
|
|
|
Hi,
don't serilize it directly to a file. First serialize it into a MemoryStream. Then put that one into a CryptoStrem (this article should give you the basic idea on how to use it). The output of that one can then finally be written to a file (FileStream class).
If you use the cryptographic classes correctly it will be very hard to nearly impossible for someone else to decrypt it.
|
|
|
|

Hi, tnx for your advise, but just one consideration:
if i use these lines in my code
cryptic.Key = ASCIIEncoding.ASCII.GetBytes(“ABCDEFGH”);
cryptic.IV = ASCIIEncoding.ASCII.GetBytes(“ABCDEFGH”);
it can be get in back by hackers opening my application in assembly code or just if it crash for whatever cause.
Isn't it?
My trouble is can someone got these keys? so use to decrypt manually the stream?
|
|
|
|
|
This is the problem facing everyone, and there is no way around it. There are numerous ways to make it harder for someone to get the keys, but ultimatley if you want to encode and decode from within your program then you will be susceptible to the problems you mentioned.
However, if the user is entering the key/password then it's a different matter entirely, and you can make it very secure.

I'm sorry so many people voted without giving you advice. My advice, you shouldn't do anything that will be seen in the real world for your first project. You should take the time to learn some stuff first.
A really simple way to do this is with a response.redirect statement in your page when payment is confirmed, which goes to either the zip ( which will start a download ), or the page with the zip ( which you can hide from google, but which someone will hand out, or discover, eventually. You should password protect your zip and send the password as another line of defence and a way to get your clients email addresses ( don't sell them or spam them, but do use them to send info on updates, etc. )

Suppose I have this:
public Pen[] activePen = new Pen[] { new Pen( Color.Blue ), new Pen( Color.Green ), new Pen(Color.Red) };
How to infinitely cycle through the 3 Pens?
thanx
|
|
|
|
|
Like this?
int i = 0;
while (true) {
i = i % 3;
Pen nextPen = activePen[i];
i++;
}
|
|
|
|
|
That works-thanks-- but I have one Pen array for the form and
several different g.DrawLine calls to put a few different colored
lines on the form due tied to text boxes --- thanks again
|
|
|
|
|
Well you don't need the while loop. Instead make a private member out of i and put call this method to get a Pen:
private int _penIndex = -1;
private Pen GetNextPen() {
_penIndex = (_penIndex + 1) % 3;
return activePen[_penIndex];
}
