in development environment of .net, when design mode, Application.StartPath is the path of development environment, but run the application the path is program's path. I want to get the path what it is always the application the path is program's path. How to do it?

When you're in design mode, there is no program to have a path, the IDE is actually running your code.

So....
I get UTC time from a C server in a 32-bit unsigned integer (aka long). Let's say for sake of discussion the UTC time is in the following variable:
uint utcTime;
And let's say I also have:
DateTime locTime;
And of course, there seems to be no combination of DateTime() methods that will address my simple need.
Any ideas?

I'm not quite sure what you're asking. Are you trying to turn your uint into a DateTime?
Edit:
Boy, MSDN[^] is sure helpful:
Convert.ToDateTime Method (UInt32): Return Value
This conversion is not supported. No value is returned.

Look at him. He runs like a Welshman. Doesn't he run like a Welshman? Doesn't he? I think he runs like a Welshman.

Yea, but the Uint32 that holds the time contains UTC formatted time from a C based program sent over ethernet. I pull it out of a packet, decode and now I need to be able to convert it to DateTime to be able to use it the C# app. Thanks

I believe the Uint32 value is the number of seconds since January 1, 1970 (most likely). Thus, to get the correct DateTime, you must initialize the your DateTime variable to January 1, 1970 and add the Uint32 seconds to it.

Thanks for the tip George. Here's what I have encountered:
uint uval
DateTime dt = new DateTime( 1970, 1, 1 );<br />
dt.AddSeconds( uval );<br />
Console.WriteLine( "Date is {0}", dt.ToLocalTime( ) );<br />
Here is a real result to illustrate:
2/23/2006 11:49:15 AM: Raw POSIX Date-Time: 1140713262, Conversion: 12/31/1969 7:00:00 PM<br />
I printed out the 2K/POSIX value, followed by the conversion to local time. I was thinking the conversion should have yielded a date time along the lines of the message preamble 2/23/2006 11:49:15 AM give or take a few seconds in terms of synchronization w/ the server time. However it was off by just a few years!
I was curious to what was happening so I changed the dt.ToLocalTime() to dt.ToUniversalTime() and it yields 1/1/1970 5:00:00 AM. Since the DateTime is initialized to DateTime( 1970, 1, 1 ) this begs the question of just what is dt.AddSeconds( Convert.ToDouble( uval ) ) adding?
Interestingly if I print out dt without the ToLocalTime() conversion it yields 1/1/1970 12:00 AM. That means the seconds added should be 18000 to result in 1/1/1970 5:00:00 AM. This is why I am a little suspect of the 2K/POSIX value, it doesn’t make sense to me to added a 10 digit value and only yield a 5 hour delta since the 1970 epoch.
Now I have quadruple checked the packet decoding logic and I can tell you that all fields before and those after in a variable length packet are all correct and at the appropriate offset. Thus I have revisited the decoding and it appears to be OK in every respect less the date time situation.
At this juncture I am wondering if the 2K flavor of UTC requires any special consideration. Or is there something I am just plain missing? I am stumped.
Final FYI – according to the documentation from the Server vendor, the date-time is stored as followed:
TIME 4 Bytes A date/time, expressed as the number of seconds since Midnight January 1, 1970 Coordinated Universal Time (UTC).
So at least I know I am playing with the right deck,

I have succeeded in getting my code to successfully do mouse clicks on a commercial program, running at a specific screen location, using this code:
SetForegroundWindow(targetWindowHandle);
input.type = INPUT_MOUSE;
input.mi.dx = 900;
input.mi.dy = 50;
input.mi.mouseData = 0;
input.mi.time = 0;
input.mi.dwFlags = 0;
input.mi.dwExtraInfo = 0;
SetCursorPos(input.mi.dx, input.mi.dy);
input.mi.dwFlags = (MOUSEEVENTF_ABSOLUTE+MOUSEEVENTF_LEFTDOWN);
resSendInput = SendInput(1, ref input, Marshal.SizeOf(input));
input.mi.dwFlags = (MOUSEEVENTF_ABSOLUTE + MOUSEEVENTF_LEFTUP);
resSendInput = SendInput(1, ref input, Marshal.SizeOf(input));
The problem is, of course, if the window is moved, the clicks miss. I would love to be able to do the clicks relative to position 0,0 of the window pointed at by targetWindowHandle instead of relative to position 0,0 of the screen.
(I hope that statement makes sense to you guys.)
Any suggestions?
 Thanks.

for those interested ...
The solution was rather trivial after i found "GetWindowRect" in User32:
public struct RECT
{
public int left;
public int top;
public int right;
public int bottom;
}
[DllImport("user32.dll")]
public static extern int GetWindowRect(int hwnd, ref RECT rc);
// Get the target window's screen coordinates
RECT rect = new RECT();
int hwnd = GetWindowRect((int)targetWindowHandle, ref rect);
Persistence pays ...

I need to make a calcualtor (must be able to add, subtract, divide, and multiply). Two text boxes allow you to enter numbers which in turn does the math and prints to a seperate

Which is what?
You've got to be more specific about what your problem is in order for us to help. For example, I commented that in your first post the sentence ended midstream. So we can only guess or assume what you want.
You have two text boxes.
I'm assuming you have a bunch of buttons. +, -, /, *
I'm assuming you have a textbox or label for the result.
What part isn't working? What have you tried already?

i have two text boxes, and four buttons. Each text box allows for numbers, the buttons are teh math function. They then print the answer onclick to a seperate label.
I have tries adding the strings which simply put the two numbers in the box next to one another. I have tries sending the text.tostring function to the label.......

You need to convert it to an int before you can add them. Use this method:
<br />
int x = Convert.ToInt32(
int y = Convert.ToInt32(
<br />

int x;
int y;
private void btnAdd_Click(object sender, System.EventArgs e)
{
int x = Convert.ToInt32.txtFirstNum;
int y = Convert.ToInt32.txtSecondNum;
x + y;
}
It doesn't recoginze the ToInt32! Is this supposed to be my answer label name?

Can't you at least copy/paste correctly????

In addition to my previous post.
jessica gelina wrote: x + y;
Needs to assign the result to something in order for you to use it. e.g.
int result = x + y; Then you can take the result and assign it to the Text property of your Label. (Remember to convert it to a string when you do that)
Does this help?

He is referring to the fact that you coded:
Convert.ToInt32.txtFirstNum; When the example clearly used brackets and specified you needed to pass in a string.
Convert.ToInt32(txtFirstNum.Text);

Just need to make a few changes:
<br />
private void btnAdd_Click(object sender, System.EventArgs e)<br />
{<br />
int x = Convert.ToInt32(txtFirstNum.Text);<br />
int y = Convert.ToInt32(txtSecondNum.Text);<br />
x + y;<br />
}
That should fix it

Ohh lol oops.
private void btnAdd_Click(object sender, System.EventArgs e)<br />
{<br />
<br />
int x = Convert.ToInt32(txtFirstNum.Text);<br />
int y = Convert.ToInt32(txtSecondNum.Text);<br />
x + y;<br />
<br />
}
Sorry bout that.

Sounds just like project 5 in the Basic Programming course at St Louis Community college.
Good luck.
