Hi,
the node that has been checked is supplied in the TreeViewEventArgs of the event. Use its ParentNode property to determine whether it has a parent or is a top level node.

There are no any Propety for System.EventArgs e.
please can you explain in details?
|
|
|
|
|
If you catch the AfterCheck event you will get TreeViewEventArgs and not EventArgs. I assume you probably used the Click event so far. Use AfterCheck instead and you'll be fine.

The 'AfterCheck' event occurs after the tree node check box is checked. Just delegate this event and in the function you'll get 'TreeViewEventArgs' as the second parameter.
It would have all the information you are looking out for.
For more details you can refer to the 'AfterCheck' help in MSDN.

Hi guys, im trying to write a multimonitor application, how do i move a form to the second monitor, well whats the best way? i use the following code i wrote some time ago, not sure its the best way though, i want the least amount of overhead.
using(DXQuartz frm_quartz = new DXQuartz())
{
Screen[] screen = new Screen[1];
screen = Screen.AllScreens;
frm_quartz.Location = new Point(screen[1].WorkingArea.Left, screen[1].WorkingArea.Top);
frm_quartz.Size = new Size(screen[1].WorkingArea.Width, screen[1].WorkingArea.Height);
frm_quartz.Show();
}
Any help on this would be amazing, there is probibly a built in method for this im missing, thanks for the input

Hi!
There are 2 problems with this code:
1. The assignment screen = new Screen[1]; doesn't have any effect because you're assigning Screen.AllScreens to screen in the next line.
2. The code will throw an IndexOutOfBoundsException if there's only one Screen available.
Otherwise it's the normal way to make the form fill the second screen...

Hi,
Why is it that my Convert.ToDateTime isn't working any more...
Usually when i said DateTime Test = Convert.ToDateTime(System.DateTime.Now); the value of Test was "2006/09/11 14:00:00 PM" now it is "11/9/2006" not at all what i want... Is there a setting to change this?
The regional settings are the same as when the Convert.ToDateTime work right...

|
|

try out
Test.ToString("MM/dd/yyyy");
rahul
|
|
|
|
|
I might be wrong but wouldn't this: Test.ToString("MM/dd/yyyy"); bring back the value "11/09/2006"...
I'm looking for the value of "2006/09/11 14:00:00 PM"
Usually the Convert.ToDateTime brought back this value that i'm looking for without a problem... on my friends PC this Convert.ToDateTime(System.DateTime.Now); brings back the value "2006/09/11 14:00:00 PM" but not on mine... as it brings back the wrong value format..."11/09/2006"
What could the reason be for this?
Thank you in advance...
Regards Nico

then try
Test.ToString("yyyy/dd/MM")+" "+Test.ToLongTimeString();

I really don't understand what you are trying to do because System.DateTime.Now already returns a DateTime object. So the Convert.ToDateTime() method call is redundant - it does nothing.

No, the value of Test is a DateTime object (which has no culture specific representation)

I just used the System.DateTime.Now as and example. That could be a string "2006/12/12 14:00:00 PM", The thing is ... usually when i used the Convert.ToDateTime("WHATEVER") the correct value (being "2006/09/11 12:00:00 PM" so the format was "yyyy/MM/dd hh:mm:ss") but now it brings back a value of "11/09/2006" which is "dd/MM/yyyy". How could this be? I change nothing that i know of....
Please help.

I suggest that instead of using Convert, use DateTime.Parse.
See Example from MSDN below:
using System;
using System.Globalization;
namespace Parse
{
class Class1
{
public static void Main(string[] args)
{
// Assume the current culture is en-US.
// The date is Feburary 16, 1992, 12 hours, 15 minutes and 12 seconds.
string myDateTimeValue = "2/16/1992 12:15:12";
DateTime myDateTime = DateTime.Parse(myDateTimeValue);
Console.WriteLine("1) myDateTime = {0}", myDateTime);
// Reverse month and day to conform to a different culture.
// The date is Feburary 16, 1992, 12 hours, 15 minutes and 12 seconds.
IFormatProvider culture = new CultureInfo("fr-FR", true);
string myDateTimeFrenchValue = " 16/02/1992 12:15:12";
DateTime myDateTimeFrench =
DateTime.Parse(myDateTimeFrenchValue,
culture,
DateTimeStyles.NoCurrentDateDefault);
Console.WriteLine("2) myDateTimeFrench = {0}", myDateTimeFrench);
// The date is Feburary 16, 1992, 12 hours, 15 minutes and 12 seconds.
string[] expectedFormats = {"G", "g", "f" ,"F"};
myDateTimeFrench =
DateTime.ParseExact(myDateTimeFrenchValue,
expectedFormats,
culture,
DateTimeStyles.AllowWhiteSpaces);
Console.WriteLine("3) myDateTimeFrench = {0}", myDateTimeFrench);
}
}
}
/*
This example yields the following results:
1) myDateTime = 2/16/1992 12:15:12 PM
2) myDateTimeFrench = 2/16/1992 12:15:12 PM
3) myDateTimeFrench = 2/16/1992 12:15:12 PM
*/

Okay thanks,
But why would DateTime TodayTest = DateTime.Now; produce the value "2006/09/11 12:00:00 PM" on my friend's computer but on mine it shows "11/09/2006". What could be the symptoms?

DateTime, as I've already said, has no cultural bias. It has no display format. There are a few methods on DateTime that convert it into a culturally biased string. Most of these methods take the culture of the OS (i.e. what is in the control panel for how to display date and time information). The ToString() method on DateTime can be supplied with any format you like if you want to get specific. e.g. DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")

You've asked the same question several times. I think you need to provide a little bit more information before we can help you.
Here's a few things to answer/think about:
What type of application is this? Is it WinForms or ASP.NET?
How are you attempting to print out the date? Have you printed out the DateTime.ToLongTimeString() to see if the time is there. BTW - you can't have a value of 14:00:00 PM;)
As I stated in an earlier answer to you, I suspect that your problem is the CurrentCulture. If you are using ASP.NET, then it is entirely possible that the problem is because the culture of the user that ASP.NET runs under is different to yours. To solve this, you can use a "clever" trick to sort this out.
In your Page_Load method, call the following routine:
public static void SetCulture(HttpRequest req)<br />
{<br />
if (req != null && req.UserLanguages != null && req.UserLanguages.Length > 0)<br />
{<br />
SetCulture((string)req.UserLanguages[0]);<br />
}<br />
}<br />
<br />
public static void SetCulture(string culture)<br />
{<br />
CultureInfo ci = new CultureInfo(culture);<br />
Thread.CurrentThread.CurrentCulture = ci;<br />
Thread.CurrentThread.CurrentUICulture = ci;<br />
}
If you call the first method, the user will get data presented to them in the culture that they have set up on their machine. So, somebody from France would probably get information back for the culture fr-FR. Now, calling the second method means that you can specify the culture explicitly, and the user will get information back in that culture, so the same French user would get back information with GB settings if you called SetCulture("en-GB");

No it's winforms. Thank you...i tried your previous example that you gave me...
CultureInfo culture = new CultureInfo("en-GB");<br />
<br />
DateTime dateTime = Convert.ToDateTime(_appDate+" "+startTime, culture);<br />
DateTime dateTime2 = Convert.ToDateTime(_appDate+" "+endTime, culture);
but this brought back the exact same date "11/09/2006" as when i tried just to
string _fromDateTime = _appDate+" "+startTime;<br />
string _endDateTime = _appDate+" "+endTime;<br />
FromTime = Convert.ToDateTime(_fromDateTime);<br />
ToTime = Convert.ToDateTime(_endDateTime);
but on my friends pc it brings back the value "2006/09/11 02:00:00 PM"
Sorry, in know i'm not explaing enough what my problem is but i'm not even sure what is wrong... its just when i try to compare to dates like in this example: if( _today>=vch.FromDate && _today <=vch.ToDate)
_today has the value of todays date... on my computer it is "11/09/2006" the value of vch.FromDate is "11/09/2006" and the value of vch.ToDate is "11/09/2006"... This if statement should return true... Am i right.
On my computer it returns false... ????  that is just one example... another one was yesterday's problem, but some how that sorted itself out... when the selected time "2006/09/11 02:00:00 PM" was writen into the database the the time would be inserted as AM but without the AM if that makes sense (like so: "2006/09/11 02:00:00.000)... Now it writes the time in the db correctly... "2006/09/11 14:00:00.000" Weird but true...

What is vch? Is it a calendar control or something? Could this be the source of your troubles?

the vch part is a class parameter. it is property in a class.

Try the following wrapper class and test:

_dt = dt;<br />
}<br />
<br />
public WrappedDate(string dateOnly)<br />
: this(dateOnly, null)<br />
{<br />
}<br />
<br />
public WrappedDate(string date, string time)<br />
{<br />
if (string.IsNullOrEmpty(time))<br />
time = "00:00:00";<br />
if (!time.StartsWith(" "))<br />
time = " " + time;<br />
while (time.IndexOf(" ") > -1)<br />
{<br />
time = time.Replace(" ", " ");<br />
}<br />
try<br />
{<br />
_dt = Convert.ToDateTime(date + time);<br />
}<br />
catch (Exception ex)<br />

_dt = null;<br />
}<br />
}<br />
<br />
public DateTime? Date<br />
{<br />

WrappedDate finish = new WrappedDate(DateTime.Now.AddHours(1));<br />
WrappedDate compare = new WrappedDate(DateTime.Now.AddMinutes(30));<br />
Console.WriteLine(dt.Date.ToString());<br />
<br />
if (compare.Date >= start.Date && compare.Date <= finish.Date)<br />
Console.WriteLine("Success");<br />
else<br />
Console.WriteLine("Failure");<br />
Console.ReadLine();<br />
}<br />
}<br />
}

Hi Pete, i have great news...
The problem is only on my pc. As soon as i build and install onto another pc it works fine...
The variable shows me the wrong values in the debugger but somehow it contains the correct values and writes these correct values into the database.
The problem still eludes me, but for now it at least works on the client's computers.
Thank you for taking the time to help out... 
Regards
Nico
