Hi,
I need your help for some sporadic problem that I got during starting new process (C# 1.1).
when I 'm starting new process on remote machine (using remoting), my process starts properly and launching an external application, but from some strange reason it does not exit , and the CPU is growing almost to 98% despite the fact that the application I run via this process finished its job.
Please see my code below:
Code: ( text )
proc = new Process();
proc.EnableRaisingEvents = true;
proc.StartInfo.FileName = m_AppExeName;
proc.StartInfo.WorkingDirectory = m_AppFolderName;
proc.StartInfo.UseShellExecute = false;
proc.Start();
10x,
Lior

Hello,
Two Point's that come in my mind:
.)
Are you holding the reference to the Process all the time or are you disposing it proper.
You could use a 'using'-block for that:
using (Process proc = new Process())
{
proc...
}
.)
Why are you setting the 'EnableRaisingEvents' to 'true'.
Are you handling the 'Exited' event somewere?
All the best,
Martin

Thanks for your quick response 
I'm holding a reference to this Process indeed.
In addition, I'm using the 'Exited' event later in the code in order to get notified
when my process finished its job (notify the client).
Do u think it can cause this problem??
Thanks,
Lior

I'm really not sure about that.
Give it a try without holding the process and the delegate.
All the best,

if i declare the function in the class as public static .i now no need to create the object , like
class abc
{
public static void abc1()
{
}
}
class def
{
void abcbd()
{
abc.abc1();
}
}
what will happen if i declare the class as static?

Open www.google.com[^].
Type "C# static class".
Hit the "Google Search" button.

In this case the result will be the same. Because when you declare a method static in a non-static class you can call it without creating new object. If you declare class static, you're declaring only static methods inside... For more search google...

I have to make a clarification in the following funciton.
public SqlParameter Parameter<T>(string parameterName, DbType parameterType, T value, ParameterDirection direction)
{
}
here in the funciton <T> is declared after the funciton name.
if in the funciton parameters , i declare string value inspite of T value.
will it produce any sort of less effeciency.
I mean What's the importance of this <T> in the funciton?

Sonia - when I originally posted the snippet with the <T> parameter in, I explained to you that this was a generic. Please take a look at google and see what you can find out. When you've had a look, feel free to come back and ask questions, but this question is answered in the basics of using generics.
CodeProject is not a programming tutorial. It is not here to remove the need for you to buy a book or two. In little over 6 months, you've posted approximately 835 questions and follow up questions. Doesn't this tell you that you could get some help from other sources?
I would suspect that most people on the forums are like me, and buy books and use google a lot. These should be your first port of call EVERY TIME.

That's generics.

In this case, not really, as the value of an SqlParameter will be stored as an object anyway, but you may get type conversion problems if you for example try to store a date in a parameter, and the date format on the server is different from what the database expects.
Sonia Gupta wrote: I mean What's the importance of this <t> in the funciton?
Generics is used to create type specific code (which is more efficient than using dynamic types) without having to rewrite the code for every possible type you want to use.
A List<t> is for example used instead of ArrayList to produce type safe lists where you don't have to cast to and from Object when accessing the items.

Hi, i am new to this language but loving it. Can someone please tell me how to
Add a chm file (This is my help file that i created) to my existing c#.net project. It is a windows application.
The help will be much appreciated
|
|
|
|
|
Drag a Help Provider control from the toolbox and assign the .chm filename to it in its properties...the .chm file will be invoked on pressing the F1 key

Thanks for the reply, I tried but it does'nt display the file whem i press F1. On the properties window i specified the HelpNamespace, is this correct?
|
|
|
|
|
That's correct...set HelpNamespace="Your file location".
Also add the following code in your designer.cs under the helpprovider1 section
this.helpProvider1.SetShowHelp(this, true);

You must have used some wrong code.
Create a MouseMove event and set the Location to the point of the mouse.

Coders,
Is there an application/sample source here in codeproject
that is the same in DTS (Data Transformation Service). It will copy database from source to destination.
Can you help me, a link or something.
Thanks in advance.;)

hi all,
I have a listview where i am trying to display thumbnail images similar to windows explorer. i have set the owner draw property to true and i managed to display the thumbnails using the drawitem event.
But when i execute my application there seems to be a flickering in listing of images. i found many samples illustrating to set the doublebuffered property to true. and use setstyles property.
public mylistview()
{
//Activate double buffering
this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
//Enable the OnNotifyMessage event so we get a chance to filter out
// Windows messages before they get to the form's WndProc
this.SetStyle(ControlStyles.EnableNotifyMessage, true);
this.DoubleBuffered = true;
}
protected override void OnNotifyMessage(Message m)
{
//Filter out the WM_ERASEBKGND message
if (m.Msg != 0x14)
{
base.OnNotifyMessage(m);
}
}
but still the flickering occurs. i found a article Flickerfree listview
here^
but that does not seem to work perfectly.
Can anyone help me with some links or suggestions??
Thanks in advance.
Regards
Anuradha
