hard code ur Key to ur program and check with the input. if the input matches the Key u hardcoded into ur project, execute it or else just pop up a message telling wrong product key! Try again.

3D Model Viewer

I have no experience w/ directx. So, i'm looking to learn. In particular, I want to take a 3D model of an object and display it on my app using directx. Also, I want to feed that model X,Y,Z values and have it rotate itself respectively.

Can somebody point me to an example or something that does something link this? Also, I don't know how to make my "model" either, i'd be happy if it was just a square. Do I create it in some 3d app and then load that file into directx?

For example, say I have a square model. I just want to show it in my C# win form and send it some Cartesian values X,Y,Z and have it rotate relative to some point.

Your absolute best bet would be to use Avalon/WPF/.NET 3.0, a new framework ( still in beta ) that gives you a lot of control over how the UI looks.

How to convert Integer value to Datetime value?

bigeyed31-Jul-06 14:32

Hi..

I get 5 int values
For instance, they will look like the below...
int a = 2006; //year
int b = 3; //month
int c = 5; //day
int d = 1; //hour
int e = 3; //min
int f = 2; //second

but I want to put them in DB looks like "20060305010302" which means..
year has to be 4 digit, month has to be 2digit, day has to be 2digit..and so on...

so if I get the month data number 5, then I have to be able to convert number to 05 (because the DB column character is set for "yyyy:MM:dd:HH:mm:ss".

can I do this in one shot?? I can't think of anything good...
what i'm thinking is that comparing the length and if the length is shorter than 2 then, put the "0" in front of the number.... -_-...

please help... thanks

You can create a DateTime object and then use a Custom DateTime Format String.

For Example, this generates the output you want:
DateTime d = new DateTime (2006,3,5,1,3,2);
d.ToString ("yyyyMMddhhmmss");

MSDN Custom DateTime Format Strings

Hope this Helps,
Chris

Slight correction to the format string; "hh" gives hours in the range 1-12, use "HH" to get hours in the range 0-23:

DateTime d = new DateTime (2006,3,5,1,3,2);<br />
d.ToString("yyyyMMddHHmmss");

Detecting Ctrl + arrow keys

I need to distinguish Ctrl and Ctrl+arrow key commands in my app. Using ProcessCmdMsg rather than OnKeyDown handler allows me to register arrow keys, but when user strikes and holds Ctrl key, there are lot of messages with key code equal to this Control key, bud I'm not able to detect both Ctrl as modifier key and arrow key at the same time.

You can please try the below:

private void Form1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
	if ( e.Control && e.KeyCode == Keys.Up )
	{
		this.Text = "Control key + Up Key pressed";
	}
	else
	{
		this.Text = "Other Key pressed";
	}
}

static keyword like C++

how to do like it was in C++
int fun() {
static int i = 0;
i++;
}

in general - i want a static varible in method - not static for all class but static only for one method..

Ideal compilator compiling comments without code...

There are no static local variables in C#.

Declare it in the class. It's stored exaclty the same as a static local is in C++. The only thing that differs is the scope.

If you write a variable in a method and does not make it global it will be static only for that function not for all classes.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
