hi there
i am trying to develop an application similar to the laser game
I have tried many ways to deflect the laser beam (a line that i drew from a point to the mirror)
I am using a movable label control to repersent the mirror
any ideas on how to go about this problem???
Thanks
regards
Yasin

You should handle all drawing in a paint event handler. You just can't do it wth controls, not nicely. The deflection is basic physics. Which bit are you stuck on, drawng the line, or working out where it goes ?

As I said before[^] forget the Label, it only complicates matters.

- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information
- before you ask a question here, search CodeProject, then Google

Forget the controls and rendering code for now. You haven't figured out how to represent your game's data properly yet.
The graphics you see in any game is a visual representation of the game's internal database. You can't possibly draw anything until you've got your data representation and management worked out.

Hi all,
I have an urgent question.
I am writing an windows service to retrieve files from a network drive mapped as Y: I get the following error... Could not find a part of the path "Y:\verify".
When I run an Application it works fine, so I tried to shell the exe from my service, but still get the error!
I have read and tried several things but to no success 
Can anyone please assist me?

Have you tried the UNC e.g. instead of :
"Y:\somefile.txt"
Try (depending on the path):
"\\FredsComputer\C$\somefile.txt"
You always pass failure on the way to success.

Yes I have tried that, but the share needs authentication.
So I get access denied error
|
|
|
|

Sounds like a permissions/user issue.
I am not a networks expert and I guess someone else on this forum may be able to help.
Good luck...

A Windows Service runs, by default, as the Local System account, which has no rights to any network resources. The service does NOT run under the user context. It runs as if a seperate user logged into the machine (actually it DOES login to Windows) with no network permissions.
To the service, there is no Y: drive. The only drives that exist are the local floppy, hard drive, and any CD/DVD drives.
If you want the server to have access to the network, you have to change the account it's running under to one that has network permissions. Click Start/Run and type services.msc. Find your service in the list and double-click it. In the dialog that shows up, click the LogOn tab to change the account.

Thanx for the reply.
I have tried that approach but maybe i'm doing something wrong?
I log in with a domain account, so in the service properties I
specify my logon details. But then I run the service it can still
not access my mapped drive 
Got any idea why it would do this?

DO NOT CROSSPOST in multiple forums. It makes collaboration on an answer impossible.
Did you map the drive by hand yourself at any time or did a login script do it for you?? If it wasn't through a login script, then the service will not see the mapped drive because it hasn't mapped it itself.
Using mapped drives is a bit old-fashioned anyway. If you used UNC paths, you haven't have to worry about the mapping at all. The service still needs to run under a network account though.

Because the service logs in under its own security context. It's not aware that you logged in under the same account. It's completely in its own litte world. Nothing you do under your account will affect what the service sees.

The reason why it doesn't work now is because you're using multiple binding sources. Knock that back to one binding source and update all the bindings and it'll work without any code.

If e.button = vb.VB6.MouseButtonConstants.RightButton Then
ContextMenu1.MenuItems.Clear()

ContextMenu1.MenuItems.Add(menu1)
Me.ContextMenu1.Show(AxTreeView1, New Point(e.x, e.y))
End If

Hi every one..
i have 2 buttons and one label..
if i click accept button time starts from 0 and if i click hangup button the label must dispaly how much time it hasd taken between two clicks....
can any body guide me how to achieve it....
|
|
|
|
|
put a timer on the form
put timer interval at 1 sec
on click of accept button start timer
on every timertick you increase a global variable by 1
on click of hangup button stop timer
do some calculating with the global variable and you know how much time past
(I'm sure there are better ways to do this but don't have the time to look for one at the moment)
If my help was helpfull let me know, if not let me know why.

A more accurate way than was suggested:
DateTime start;
button1Click
{
start = DateTime.Now;
}
button2Click
{
TimeSpan elapsed = DateTime.Now - start;
}
This approach is more accurate and simpler than playing with timers.
