Hi,
Sorry to disappoint you, but i wanted to ask my own question in this.
Are you able to detect when the user is clicking on the window in the taskbar?
Actually, i have made a program in which i have made the FormBorderStyle as None. This prevents the system menu to appear when i click on the window in the taskbar.
So, i wanted to figure out a way in which i could detect a click on the taskbar window and display the menu manually.
Please let me know, if you happen to know about this.
Thanks in advance.

I think, i am getting your problem.
See, when you pop-up the message box, the event is still being fired and it still shows the taskbar menu too, but the message box removes the focus and hence makes the taskbar menu disappear.
Secondly, the fact that the taskbar menu is appearing shows that you are able to hide the icon successfully, but somehow another event is being generated which is being sent again.
I am not sure about how this is happening, but i guess, you can refer to this article[^] for more details.
Also, i hope, you are using the NotifyIcon control. It saves a lot of time.
I hope this helps.

Hello!
I have wrote a code in which i m trying to hide the Notification icon when i click on the context menu (which pops on that icon). BUt in this manner two events fire. One which is my event written in the code(which works according to my requirement) and other is the Windows own event, which is Taskbar Popup menu. which always seems bad. if i call any messagebox after that fired events, the windows event hide but i don't want to show message box. Please help me.

I think this will solve your problem :
try {
int port = FindUnusedPort(IPAdress.Any);
}
catch (SocketException) {
// no free ports
}
...
using System;
using System.Net;
using System.Net.Sockets;
...
public int FindUnusedPort(IPAddress localAddr) {
for (int p = 1024; p <= IPEndPoint.MaxPort; p++) {
Socket s = new Socket(AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp);
try {
s.Bind(new IPEndPoint(localAddr, p));
s.Close();
return p;
}
catch (SocketException ex) {
// EADDRINUSE?
if (ex.ErrorCode == 10048)
continue;
else
throw;
}
}
throw new SocketException(10048);
}
Cheers

I want help in opennig only one child file at a time. My application irritates me when there are too many child forms open.
I added this code (on all the menu items) to open only one, but the problem is that, I can't open another child while there is a child active. How do you control that ?
Interfaces - Is the folder Name where all forms are located
frmPerson - is the child form (requered form to open)
private void mnuManagePerson_Click(object sender, System.EventArgs e)
{
if (Interfaces.frmPerson.ActiveForm.ActiveMdiChild == null)
{
Form frmchildfrmPerson=new Interfaces.frmPerson();
frmchildfrmPerson.MdiParent = this;
frmchildfrmPerson.Show();
}
}

Make the base class of your child form to implement the singleton pattern

How do i manipulate hashtables in c# ? i could store objects into hastables but i get problem while retrieving them back.
i tried this :
<br />
Dictionary<string, string> openWith = <br />
new Dictionary<string, string>();<br />
[here i intend replace "string" with my own object type]
but it failed,
may be because it failed even when i tried to include this
using System.Collection.Generic;
it says like "are you missing any assembly reference?"
BTW, just like we have vectors in C++, what's the equivalent container in C# ?

A potentially dangerous Request.Form value was detected from the client.
I have a webpage using .net 2.0 with
an asp:button Back and
a textbox with text = "<space>"
I've done my research and everything I see says set ValidateRequest="false" in page directive which I did.
There's no problem if I click the browsers back button. But when I click my own asp button BtnBack, the error is produced. Is there something like setting the validation within my own button?
Thanks!

Hi,
When browser back button is clicked, no new request is sent to browser, I think(unless we expire the page programmatically). Most probably, you have written a Response.Redirect in your asp button click, right? So, the html code gets posted to the server and server generates the error.
You can either call History.Back(or something like that in javascript) in your button click or you can set ValidateRequest = "True"
Regards,
Jim

Hi there,
I have an urgent need for help. I'm currently on a project where I'm developing an Indigo service
(CTP Feb 2006) which is hosted in IIS 6.0 on a Windows 2003 server. This service needs to access a COM component.
First, I tried registering it on the server (regsvr32) and accessing it, but I always get E_NOINTERFACE.
Second I tried to isolate the component and deploy it with a manifest.
But it still doesn't work. I get another COM error (Sorry, don't remeber the actual number but it was something like 80040154).
Now I actually have two questions:
1. Can anyone tell me what I'm doing wrong, and
2. Does anyone know if the isolation of COM components is possible on W2K3 server.
Many thanks in advance

Good day to all,
Currently im developing an administrative tool that allows me to monitor all workstation under my domain. I want to do remote shutdown/restart/log-off using C#. At first I was thinking of executing the ff:
shutdown -r -f -m \\pcname -t 0 for restart..
shutdown -s -f -m \\pcname -t 0 for shutdown..
I planned to execute it under C# Process & ProcessStartInfo however i feel i doesnt much have control because whenever i shutdown/restart an offline pc, if it is on command line, then it will just hang-up or just a cursor blinking and will not exit the command (maybe it would take too long..). I hope somebody could help me find a way to execute shutdown/restart/log-off remotely which we have better control and more reliable way. Also also want to get remotely,the processes that runs under the client machine/workstation, i hope this is feasible in C#.
Im using .NET 2003 environment,
thanks a lot,

Try this :
string t = "-r -c \"I am going to reboot your mechine\" -t 20";
Process process = new Process();
process.StartInfo.FileName = "shutdown.exe ";
process.StartInfo.Arguments = t;
process.Start();
I think this will solve your problem.
Cheers

Hi Jijo,
Thanks for your reply. I guess i will just have to use shutdown.exe and continue using Process and ProcessStartInfo.
More power to you!

Hello,
I'm working on a localized project and have the following problem now:
PROBLEM:
The Visual-Studio-2003-Designer does not show the correct language. What i did is that:
WAY:
1. Create a new WindowsForm-Project and place a button on the form.
2. Add a new userControl and place a button in the userControl (compile it).
3. Place the userControl on the Form.
4. Localize the project to "invariant", "german", "english"... (compile...)
I named all buttons according to the localized language (invairant, german, english).
EFFECTS:
When I now open the Form with the designer, and the language of the Form is set to "invariant", the button of the form is named "invariant" but the button of the control is named "german". It doesnt matter in wich language set when I compile the userComponent. Most of the time it's "german" (sometimes I saw "invariant" but I couldnt figure out why  ).
During runtime everything works normal and I can see the language that is set in "System.Threading.Thread.CurrentThread.CurrentUICulture". 
PRESUMPTIONS:
I suppose that it may depend on the language of the Visual Studio or on the language of Windows (both is german in my case). But I would like to understand WHY EXACTLY this happens (and what I can do to prevent it).
Thanks in advance
