Hi
I have a Sql Server datebase in our company on a Server.
I want to read the server Time from the clients and i don't want users can change their computer time .
but I don't know how can i do it.please help me
|

|
|
With SQL Server, you can run the following select statement to get the time:
SELECT GETDATE()
To set the time, read the source code of the NTPClient class from the article SNTP Client in C#.
To prevent users from changing the clock, investigate the "Change the system time" policy for users in your domain/local computers.

I have an problem in converting the desktop coding in Windows Serice. all the code was translated successfully but the problem i m facing in below code of line when i trying to write this line of code in wnidows service its getting error in Invoke method, its compulsory for me to call this (INVOKE)method cause the parameter inside this are delagate and collection of parameters that i have to pass these in any case, so can any one tell me what should i do to access this INVOKE method in windows service.
Code: this.Invoke(new PingStartedEventHandler(netMon_PingStarted), new object[] { sender, e });
|

I presume you're moving this code from a Windows application? If that's true, then the Invoke you are talking about would be Control.Invoke, which I *think* won't be available in a Windows service.
If you're not updating UI elements, I guess you can safely skip the Invoke and directly call the method using the delegate.
PingStartedEventHandler pe = new PingStartedEventHandler(netMon_PingStarted);
pe(sender, e);

hi everybody,
I would like to ask a question here.
Is Static function advantage or disadvantage ?

Thank for answering my questions ,

Depends on the context. Static functions are useful for factory methods like Create, which create and return appropriate objects.
dinh van hai wrote: How are they disadvantage ?
Static functions are like global functions, only that their scope is restricted to the class. So too many static functions and the class then becomes a dumping ground where you keep adding functions that don't fit elsewhere.
dinh van hai wrote: Shuold I use many static function in a program ?
Of course you can. You can take the system defined static functions, like File.Create as a starting point.

Senthil

how do static functions affect the performence and memory of our program ?
|
|
|
|
|
If the function doesn't use any data from the instance of the class, it should be static, so that you don't have to create an object just to call the function.
Declaring a function as static also supplies the information that the function is self-contained and doesn't need any data from an object.

Hi together!
I'm currently searching a way to get a Process by it's window title, not by it's classname...
in following code, the GameName would be, e.g. "sol" (means Processname of game "Solitär")
<br />
static ProcessMemoryReaderLib.ProcessMemoryReader pReader;<br />
static Process[] myProcesses;<br />
<br />
public static void InitRWCode(string GameName)<br />
{<br />
pReader = new ProcessMemoryReaderLib.ProcessMemoryReader();<br />
myProcesses = Process.GetProcessesByName(GameName);<br />
}<br />
that's the code i'm currently using...
but i'm looking for something like that:
in this case GameName would be "Solitär" instead of "sol"
<br />
static ProcessMemoryReaderLib.ProcessMemoryReader pReader;<br />
static Process[] myProcesses;<br />
<br />
public static void InitRWCode(string GameName)<br />
{<br />
pReader = new ProcessMemoryReaderLib.ProcessMemoryReader();<br />
myProcesses = Process.GetProcessesByWindowTitle(GameName);<br />
}<br />
Has someone an idea 
I've already tried the GetWindowThreadProcessId together with the FindWindow, but it returns the wrong ID...
Thx for any suggestions!!!

Hi! Thanks for your reply!
Yes of course - and that's the problem. In my case it's too slow - i'm working with hotkeys. And every time a hotkey is pressed, it needs to get the excact handle of the window. So every time GetProcesses is called. And that's very slow. So i have to get the window handle directly by it's window name - that's a lot faster!!! than GetProcesses!!!. So if anyone have a suggestion... Please let me know...
Thx!

Hi, I'm using SgmlReader to obtain the XML data from a web page and I have an IndexOutOfRangeException exception when I execute the Load method from the XmlDocument class.
I had no problems before but now it started to happen.
Here is part of the code:
string path = @"C:\....";
StreamWriter w = new StreamWriter(path+"file.txt",false,System.Text.Encoding.Unicode);
SgmlReader r = new SgmlReader();
r.DocType = "HTML";
r.Href = "http://www.webpage.com/page.htm";
XmlDocument xml = new XmlDocument();
xml.Load(r); <-- Here the exception is threw.

Sam,
You might want to read "Test Run: Low-Level UI Test Automation," specifically the section "Manipulating the App and Checking App State." by James McCaffrey.
In that section, he has the following code:
public void ClickOn()
{
uint WM_LBUTTONDOWN = 0x0201;
uint WM_LBUTTONUP = 0x0202;
PostMessage( this.ptrToWindow, WM_LBUTTONDOWN, 0, 0 );
PostMessage( this.ptrToWindow, WM_LBUTTONUP, 0, 0 );
}where this.ptrToWindow is an IntPtr that stores the target window's handle.
He then explains about the two last parameters to the PostMessage call.
When processing the WM_LBUTTONDOWN and WM_LBUTTONUP messages, the wParam value indicates whether various key-state masks like MK_SHIFT are down. The lParam value represents the x and y coordinates of the cursor relative to the upper-left corner of the window. Here I pass 0,0 to WM_LBUTTONDOWN and WM_LBUTTONUP in order to simulate mouse clicks on the upper-left corner of the target window without any keys pressed. Hope that helps.

Unfortunately, the only way that I know how to send those mouse-click messages is through the Win32 API methods SendMessage and PostMessage. I mean, to click where the mouse is, you could use the EnumWindows Win32 API call, find which window the mouse is under, do some quick math to get the position relative to the window's (0,0) coordinate, and then send the PostMessage/SendMessage to that relative coordinate.
In .NET, I just don't know any other way because of the security involved. Sorry. Hopefully someone else will give you a more satisfying answer. <grimace>

How to create manually DataSet with 3 columns and 3 rows and then make gridView from it?
I have such a code:
DataSet myDataSet = new DataSet();<br />
myDataSet.Tables.Add();<br />
myDataSet.Tables[0].Columns.Add();<br />
myDataSet.Tables[0].Columns.Add();<br />
myDataSet.Tables[0].Columns.Add();<br />
myDataSet.Tables[0].Rows.Add(true,"aaa", "bbb");<br />
myDataSet.Tables[0].Rows.Add(true, "aaa", "Bbb");<br />
dataGrid.DataSource = myDataSet;
Where is myDataSet is DataSet, and dataGrid is gridview with 3 columns, first is checkbox column and other two is text columns.
But this code dont work.

How about the following code?
DataSet myDataSet = new DataSet();
myDataSet.Tables.Add();
myDataSet.Tables[ 0 ].Columns.Add();
myDataSet.Tables[ 0 ].Columns.Add();
myDataSet.Tables[ 0 ].Columns.Add();
myDataSet.Tables[ 0 ].Rows.Add( new object[] { true,"aaa", "bbb" } );
myDataSet.Tables[ 0 ].Rows.Add( new object[] { true, "aaa", "Bbb" } );
dataGrid.DataSource = myDataSet.Tables[ 0 ];

thank you. It helped.
But I still have one little problem. How to make the first column with checkboxes?
I've tried first to make gridView with three columns. and the first was checkboxes. But when I make:
DataSet myDataSet = new DataSet();<br />
myDataSet.Tables.Add();<br />
myDataSet.Tables[ 0 ].Columns.Add();<br />
myDataSet.Tables[ 0 ].Columns.Add();<br />
myDataSet.Tables[ 0 ].Columns.Add();<br />
myDataSet.Tables[ 0 ].Rows.Add( new object[] { true,"aaa", "bbb" } );<br />
myDataSet.Tables[ 0 ].Rows.Add( new object[] { true, "aaa", "Bbb" } );<br />
dataGrid.DataSource = myDataSet.Tables[ 0 ];
Thats adds 3 more columns to my gridView.

And i want to make in gridView 3 columns total. And first checkboxes.

How about this?
DataSet myDataSet = new DataSet();
myDataSet.Tables.Add();
myDataSet.Tables[ 0 ].Columns.Add( "My Bool", typeof( bool ) );
myDataSet.Tables[ 0 ].Columns.Add( "My String 1", typeof( string ) );
myDataSet.Tables[ 0 ].Columns.Add( "My String 2", typeof( string ) );
myDataSet.Tables[ 0 ].Rows.Add( new object[] { true,"aaa", "bbb" } );
myDataSet.Tables[ 0 ].Rows.Add( new object[] { true, "aaa", "Bbb" } );
dataGrid.DataSource = myDataSet.Tables[ 0 ];
