i have in my Employees table a filed that hold the start date of worker
and i nedd to get a message when the worker get 7 month of work
i try to do this :
while (reader.Read())
{
DateTime dt = (DateTime)(reader["Sdate"]);
//DateTime dt2 = new DateTime(dt.Year, dt.Month, dt.Day);
DateTime tomorrow = DateTime.Today.AddDays(360);
TimeSpan Diff = tomorrow - dt;
if (dt > tomorrow && dt < tomorrow)
this.listBox1.Items.Add("העובד " + reader["Fname"].ToString() + " ת.ז" + reader["ID"].ToString() + " נכנס ל 7 חודשי עבודה ");
and its dosent work where is ths problem ?
thanks alllooottt ....

For one thing, your if statement will never evaluate to true. You're checking the following:
if (dt > tomorrow && dt < tomorrow)
You can never have a date that is greater and less than another date at the same time. Plug in a test value:
if("1/2/2005" > "1/1/2005" && "1/2/2005" < "1/1/2005).... They can't both be true.
Also, if you're trying to check for 7 months why are you adding 360 days? Shouldn't you use
DateTime.Today.AddMonths(7)
|

|
|
|
so what do i need to do to make this work ?
|

You should really try debugging on your own. It's a good exercise in problem solving. *ALSO NOTE* I'm providing this for reference, without warranty of any kind since I'm totally unclear on your overall goal.
DateTime dt = (DateTime)(reader["Sdate"]);
DateTime dtSevenMonths = DateTime.Today.AddMonths(-7);
if (dt < dtSevenMonths)
{
this.listBox1.Items.Add(......);
}

Hello:
From a class I want clean a place holder contained in a web form.
I’m using this code:
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
namespace WUC_CreDes
{
public class Class1
{
public static bool Hay_PostBack()
{
WUC_CreDes.WebForm1 parent1 = (WUC_CreDes.WebForm1) this.Page;
parent1.Example.Controls.Clear();
return false;
}
}
}
Where “Example” is my place holder within the web form.
When I compile my Project it’s sending me this error: “Keyword ‘this’ is not valid in a static property, a static method or as startup of static field”.
Does somebody has some idea about how can I attain it?
Thanks you in advance.
Greetings.

Finally I attained it thus:
In WebForm1 I did:
bool que = WUC_CreDes.Class1.Hay_PostBack(this);
And in my class I did:
public static bool Hay_PostBack(WUC_CreDes.WebForm1 parent1)
{
parent1.Example.Controls.Clear();
return false;
}
But now I need do same from a WUC, if I do:
bool que = WUC_CreDes.Class1.Hay_PostBack(this);
I understand I need replace 'this' with web form's name, here WebForm1.aspx
Somebody know how can I do to attain it?

If I use: bool que = WUC_CreDes.Class1.Hay_PostBack(this.Page); it's sending me an error when I compile: Argument '1': it's not possible convert from 'System.Web.UI.Page' to 'WUC_CreDess.WebForm1'
May be I'm coding something wrongly but what?

i already did in VB few month ago, and i want to do the same in C#. the function insert in DB the info i get in excel and works well.
' example in VB
public function myFunction(byval LastName as string, byval FirstName as string, optional Email as string="NA", optional PhoneNbr as long=0)
end function
// now how can i do the same in C#?
i can do with polymorphiste but if some function have 20 argument, i need 400 different functions to do the equivalent of vb?
the missing value work, but i need to put all the argument in object type.

If all ur optional parameters are the same type, u can use the 'params' keyword. U could use it even if they weren't the same type, but u would need to use an object array which u dont want.
Otherwise, the only solution is to overload ur 400 different functions, C# does not support optional parameters.

Hi,
I have a procedure that takes the bill of material for a part
and gets all the routing for each component in the bill.
I would like to create a gant chart in Microsoft Project to show the
time line for creating each component required. I have been
looking all over the place for information on using C# with
Microsoft Project but with not much luck.
Any advice would be great
Thanks
Will

I want to use a base class to enforce that any children must implement a property and that property must be static and exist at the child class level NOT the base class. The compiler will not allow abstract statics , does anyone know of an elegant work around ?
|
|
|
|
|
Abstract & static would be an oxymoron, something cannot be both as an abstract member implies that a derived class will implement. If it were static there would be no derived class.
Im not sure I personally understand what you are trying to achieve.

Hi all.
I'm trying to read in the date and time from a binary file that was created using mfc. The cTime class was used to create the time stamp. I'm using a TimeSpan object and a DateTime object in order to get the date and time that was saved in the binary file. i.e.
public Count(BinaryReader read)
{
TimeSpan span = TimeSpan.FromSeconds(read.ReadUInt32());
TimeStamp = new DateTime(span.Ticks);
CountNumber = read.ReadUInt32();
}
The date and time returned ends up coming out as 18/02/0035 16:00:01 which is obviously incorrect as this is old data not future data
I looked at the number of ticks returned in span.Ticks compared to the current number of ticks (at roughly 15:22 today)
632460649505030970 - Today
10771200010000000 - Returned from the file.
As you can see there is a big difference and im pretty sure this data is only a year old at the most.
If anyone knows what i'm doing wrong it would be greatly appreciated.
Cheers
Kev

I get the correct date returned when i create a DateTime object with the "Current" number of ticks 632460649505030970 but when i create one with the number of ticks created using the reader i'm getting the date mentioned above, 18/02/0035 16:00:01 which is very wrong.
For some reason the number of ticks that i get returned from span.Ticks must be wrong.
Any ideas anyone??

A good article, but it seems to cover everything except what i want. The mfc class being used to store the time is cTime and the article mentions that this class provides an overload for the >> and << operators which are being used to store the time.
The article just doesn't go into any details about how they are overloaded. The time is being saved using the >> (or <<, cant remember :-P) operator and i need to read it into a C# class in such a way as i can get at the date and time. I thought, as did leppy from his comments, that what i did would work but it doesn't so i assume that cTime stores the dateTime in a different format.
If anyone knows how to do this it would be great. I dont need to know why it doesn't work i just need a way to read the cTime data, that has been stored using the >> operator, into a DateTime class in C#.
Cheers

The point is that cTime stored the numebr of seconds since Jan 1, 1970 12:00am and the .NET Framework epoch is Jan 1, 0001 12:00am and stores the number of 100 nanosecond intervals since then. You'll have to do a little bit of math to convert the number of seconds to the number of ticks, then use that to create a DateTime object out of the result.

OK, so the number im reading in was stored based on seconds since 1970 but the Dot Net framework's times are based on 100 nanoseconds since 0001??
