I think u have to add ":" while calling the javascript function like this
body onunload="javascriptCloseHelp();">
change this to
body onunload="javascript:CloseHelp();">
Similarly change others also
Hope now it'll run.

I need to following filter in a dataview:
EventTime > '7:00' AND EventTime < '12:00'
But it simply doesn't work. The result is an empty grid showing up.
All properties have been linked correctly. So it should be something with this filter. Can anyone tell me how to use time as your RowFilter?

Hi,
How can i develop a application which can execute once and the executive file would be removed from device. Like: After program show a message, this executive file is removed. I got a straight way that after the application executes, deleting this application file. But how? Running program couldn't delete itself. Any suggestion is welcome. Thanks!
Regards, ginee

Hi!
I don't think that it is possible to delete a program that's running, but you could add an entry to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce to delete the file at the next system start.

You can't delete the .EXE file if it's running, or any of it's loaded .DLL's for that matter.
Your app would have to launch an external process, that handles changing out the executable you want to replace, then quit. This external process (.EXE) would have to wait for the original app to quit, then it could change out any of the files that it needs to upgrade or modify, then when done, launch the original app, then quit.

A simple solution would be to use a batch file (.bat) to run your application. You could run the executable from within the batch file and when you have exited the main application it could delete the executable. I use something like the following to quickly write a test sample, compile it, run it and then delete it when the app is done:
csc /target:winexe test.cs
pause
test.exe
del test.exe

In my "Drag Enter" method, how can I get the path of the file I dragged? Is it in the IDataObject somewhere or what?
/\ |_ E X E GG
|
|
|
|
|
AFAIK path and name are the dragged String data:
<br />
private void control_DragEnter(object sender, System.Windows.Forms.DragEventArgs e) {<br />
String droppedItem = (String)e.Data.GetData(typeof(String));<br />
}<br />

Dosn't seem to work.....

Hello,
I am creating a custom schedule control similar to the way Outlook behaves.
I am having some difficulty trying to graphically/visually resolve conflicting appointments on a schedule.
Anyone have some ideas or a pointer or two to help me out?
Thanks,

i want, form another form, and at a specified condition, to create an object from a certain control and add it to the first form, like :
namespace Win
{
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1 = new Button();
private System.Windows.Forms.Button button2 = new Button();
public System.Windows.Forms.Panel panel1;
public Form1()
{
InitializeComponent();
}
static void Main()
{
Application.Run(new Form1());
}
private void button1_Click(object sender, System.EventArgs e)
{
this.Close();
}
private void button2_Click(object sender, System.EventArgs e)
{
Form2 f2 = new Form2();
f2.Show();
}
}
public class Form2 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1 = new Button() ;
public Form2()
{
InitializeComponent();
}
private void button1_Click(object sender, System.EventArgs e)
{
Button b = new Button();
b.Text = "Hello" ;
Form1 f1 = new Form1();
f1.panel1.Controls.Add(b);
}
}
}
this code does not work. What is the wrong here ?
thanks

In Form2.button1_Click you're creating a new instance of Form1, adding a Button to its panel1 control and... well, that's it. f1 is going the way of the dodo bird when the method exits.
What I think you're trying to do is add the Button to the instance of Form1 that called Form2.Show in the first place. You'll need a reference to that object in Form2. You can pass it in Form2's constructor or as a property. Here's an example:
public class Form2 : Form
{
Form1 _form1;
public Form2(Form1 form1)
{
_form1 = form1;
}
private void button1_Click(object sender, EventArgs e)
{
_form1.panel1.Controls.Add(b);
}
}
public class Form1 : Form
{
private void button2_Click(object sender, System.EventArgs e)
{
Form2 f2 = new Form2(this);
f2.Show();
}
}

I don't see the method InitializeComponent. Either create it, or get rid of this line

The project I'm developing is an Explorer bar which loads and saves files. Because it's an Explorer bar, the target output is a DLL (C# assembly). When the saved files are double-clicked, I would like to launch the Explorer bar.
Is it possible to setup an open handler within the DLL, rather than writing a helper EXE that will launch the Explorer bar, etc.? I like the idea of keeping the open-file handler bundled with the Explorer bar in the same DLL. In the mean time, until I hear from someone, I'll work on a helper EXE.
Thanks!

I am not sure about this one:
What about rundll32.exe ?
You, IMHO, should be able to associate an extension not only with an executable, but also with an executable with custom parameters.
If I am right here, you could then simply associate your extension with
"rundll32.exe mydll.dll MyExplorerBarStarter" or something like that.
I am not sure it will work with .NET-DLLs though 
Cheers

Hello all,
I have a simple custom control I use to draw an ellipse. The code is shown below. The problem is that if one ellipse is drawn INSIDE the area of another, the larger of the two always gets displayed in the foreground despite the z-order of the smaller ellipse. In fact, I can call BringToFront() on the smaller ellipse all day and the larger ellipse still gets displayed in the foreground.
I really don't understand why this is. Could someone more versed in painting custom controls help me out?
Thank you,

Unbelievable. I'm sitting here studying for my MCSD C# exam, and I decided to check this thread. If you are right, I just wasted 12 hrs. writing code that determines if an ellipse has been stacked on, in front of, or somewhere in the area of another ellipse. The code then draws the overlapping ellipse region on the ellipse considered to be backward in the z-order. All great but this post would have saved me tons of time. I must have accidentally deleted the CodeProject email regarding your response amidst all the spam I normally receive.
Well, I'll let you know ... thanks for the post leppie. BTW, xacc-ide looks sweet! I can't wait to test my C# insertion sort dll in mono, it's gonna be my first mono project.

Leppie, you are a master of custom control drawing. In fact, you may just be THE master. Thank you!!!

Eeeek Mon!,
I'm trying to use the following function from the WinInet API in order to read an "Internet Settings" setting (IE) for "Check for newer versions of stored pages"
BOOL InternetQueryOption( HINTERNET hInternet,
DWORD dwOption,
LPVOID lpBuffer,
LPDWORD lpdwBufferLength
);
So I try dis in c#...
[DllImport("Wininet.dll")]
public static extern int InternetQueryOption (IntPtr hInternet, int dwOption, char[] lpBuffer, int lpdwBufferLength );
public static char[] getInfo2(){
char[] buffer=null;
int iLen = 0;
int iRet = InternetQueryOption (IntPtr.Zero,INTERNET_OPTION_END_BROWSER_SESSION, null, iLen);
buffer= new char[iLen];
int iRet2 = InternetQueryOption(IntPtr.Zero,INTERNET_OPTION_END_BROWSER_SESSION, buffer, iLen);
return buffer;
}
}
Calling it 1st time for size and 2nd time to fill in 'buffer');
It compiles/runs but gives me back nothing.
Help mi mon!
Yo help appreciated mon!

Should it be defined as:
[DllImport("Wininet.dll")]
public static extern int InternetQueryOption (IntPtr hInternet, int dwOption, IntPtr buffer, ref int dwBufferLength );

But then how do I use IntPtr to get a value back? I need the value of buffer.
