Hello to all!
I've got problem with getting values from combobox. Code below how i get data from database and populate it in combobox. The problem is that few lines below this code i need to get value member value when something is selected in this combobox. With this code VS compile successfully. But the result is not correct. I'm not sure that this code actually works correct.
comboBox2.ValueMember = Issues.Tables[0].Columns[0].ToString();
If you understand me can you help me? 
String ConnStr = settings.ConnectionString().ToString();
String SQLIssues = "SELECT issueid, projid, summary FROM issues";
SqlDataAdapter IssuesAdpt = new SqlDataAdapter(SQLIssues, ConnStr);
DataSet Issues = new DataSet();
IssuesAdpt.Fill(Issues);
foreach (DataRow Issue in Issues.Tables[0].Rows)
{
comboBox2.Items.Add(Issue[2]);
comboBox2.ValueMember = Issues.Tables[0].Columns[0].ToString();
}
King Regards!

i have an input TextBox ,now i want to caputer the CTRL+V Acsi Code on the Textbox of the window form how can i capture ?
when i see this code CTRL+V code in the Debug mode its shows some Speical Character.

Ctrl+V doesn't have an ascii code. You need to check if ctrl is pressed and watch for V being pressed.

When I run the following code from inside the Visual Studio, it works fine, but when I run the exe, it restarts my machine.
I have written the following code:
System.Diagnostics.Process[] prs = System.Diagnostics.Process.GetProcesses();
foreach (System.Diagnostics.Process proces in prs)
{
try
{
if (proces.ProcessName.ToLower().ToString().Trim() != "" && proces.ProcessName.ToLower().ToString().Trim() != "manageallprocess.vshost" && proces.ProcessName.ToString().Trim() != "ManageAllProcess" && proces.ProcessName.ToLower().ToString().Trim() != "devenv" && proces.ProcessName.ToUpper().ToString().Trim() != "EXPLORER" && proces.ProcessName.ToString().Trim() != "Explorer" && proces.ProcessName.ToLower().ToString().Trim() != "explorer" && proces.ProcessName.ToLower().ToString().Trim() != "system" && proces.ProcessName.ToLower().ToString().Trim() != "idle" && proces.ProcessName.ToLower().ToString().Trim() != "svchost" && proces.ProcessName.ToUpper().ToString().Trim() != "SVCHOST" && proces.ProcessName.ToString().Trim() != "SvcHost")
{
proces.Refresh();
if (!proces.HasExited)
{
proces.Kill();
proces.WaitForExit();
}
}
}
catch (Exception exc)
{ }

I think you need a bit more experience before you start killing processes!

all do the same thing - you only need one of them
More worryingly, and the cause of your problem I expect, is the fact that unless the process is in your list it will be killed. This will kill all sorts of system processes by the look of it.

Yea, that is why I am putting a condition on SVCHOST and the application name through which I am running the kill process. Also, I have put a condition that all the explorer windows that are open do not get closed.
What do you suggest???

What exactly are you trying to achieve?
To me it looks like your code is trying to kill all running processes except Explorer, SvcHost and your own app. Why do you want to do this?

Exactly. This is what I want to achieve. This is a customer requirement.

This is a stupid customer requirement. Killing all processes will always restart the PC because you will be killing critical OS processes. (The only reason it doesn't when you run from inside visual studio is because VS is preventing your app from doing stupid things)
Tell your customer that they don't really want to do that. Ask them what they are trying to achieve by killing all processes.

ha ha ha. Actually they already have a third party tool which does the same thing, but does not restarts the system.
They actually want a proprietory product.

What the third party app will be doing is only killing non-critical processes.
Find out the real requirements from your customer. They don't really want to kill all processes, because that will cause a system restart. Find out what they actually want.
I suspect they want something like, close all open applications. In which case, you need to find a way of only closing user apps and not just blindly killing all system processes.
You should probably be using process.Close() instead of kill. This gives the exiting processes a chance to clean up their data.
Either way, the important point here is to ask the client what they actually want and why they want to do it.

Umh, killing svchost on Windows is never a good idea.
Besides that, why don't you call proces.ProcessName.ToUpper().ToString().Trim() just once for each process in the list? Also, comparing something not in uppercase to this string will always result in false, so the != comparison is pointless.

yea, I know that killing the svchost on windows is not good that is why I have put a check on that. Though, I guess could have written one condition for one process and not three different.
What else do you suggest please.
The problem is that when I run the application from VS 2008, it runs fine, but when I run the exe, it reboots my system.

Assuming it is related to your process stomping, put a confirm dialog ahead of each kill and wait a minute or so between each yes click. That'll let you know what process's death is taking the system down.
The requirement itself is a major WTF, there has to be a better way to accomplish whatever the clients actual objective is.
You know, every time I tried to win a bar-bet about being able to count to 1000 using my fingers I always got punched out when I reached 4....

Let me just try that. Though I tried to put a MessageBox, but that was of no help.

And it seems to me that anything other than those in his list will be killed, hence the system reboot.

Which specific process causes the system to reboot apart from the SVCHOST. We can restrict the same.

Countless ones! wininit.exe for example, winlogin too, csrss, services (and a host of services required under that).
Open you Task Manager, and start killing them and you will see. If you wanna do things in this retarded way, you will need to suffer the pain of debugging it.

Hi everyone,
I have a problem with executing some code in an Event.
In detail I use a WebBrowser control and its onDocumentCompleted Event.
When the Document is completely loaded I want to do some work (adding some event listeners to the document's mouse events).
But now, on pages containing frames, my event gets interrupted by the other frames firing the same event (I use the same method for every DocumentCompleted Event).
Does anyone know why my event gets interrupted and how I could manage to finish the event method and afterwards proceed it for the next event in queue?
Here is my code (the class ExtendedWebBrowser is inherited from the standard class WebBrowser):
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
MessageBox.Show("1");
ExtendedWebBrowser brws = ((ExtendedWebBrowser)sender);
brws.zoom = 3;
if (brws.Document.Window.Frames.Count > 0)
{
for (int i = 0; i < brws.Document.Window.Frames.Count; i++)
{
brws.Document.Window.Frames[i].Document.MouseMove += new HtmlElementEventHandler(tabControl_MouseMove);
brws.Document.Window.Frames[i].Document.MouseUp += new HtmlElementEventHandler(tabControl_MouseUp);
brws.Document.Window.Frames[i].Document.MouseDown += new HtmlElementEventHandler(tabControl_MouseDown);
}
}
brws.Document.MouseMove += new HtmlElementEventHandler(tabControl_MouseMove);
brws.Document.MouseUp += new HtmlElementEventHandler(tabControl_MouseUp);
brws.Document.MouseDown += new HtmlElementEventHandler(tabControl_MouseDown);
MessageBox.Show("2");
MessageBox.Show("3");
}
It would be fine if anybody could help me to solve the problem or give me a hint on how to search on (maybe I used the wrong words in google?!).
Maybe I have to say that I am more a novice in programming but willing to learn more 
Thanks for your help.

Because you are showing a message box from the event handler.

Don't use a message box in the event handler.
Despite everything, the person most likely to be fooling you next is yourself.

Thank you for help.
I tried it out but the problem is not really fixed.
I have the same problem when putting break points instead of the MessageBoxes.
For the main page containing the frame set, all 3 break points are reached. But afterwards the event is called by the other frame pages and I reach only the first break point. Going through step-by-step I can see that the execution is interrupted by another document completed event.
Why does this happen? Where can I find a list or sth. else with all possible things which can interrupt an event?
My next problem is that the documentCompleted event is not fired when I reload the page via F5-Key. Can anyone say what I could do to catch this event, too?
Again big thx for your help.

Hi,
I have a windows service (C#) running continously and so some values saving in memory always and at the time of stoping the service I need to save those values to an external file may be notepad etc. I am able to handle the stop event (OnStop) if it is a normal service stopping. But when the user is killing the process through task manager, I am unable to handle or track that event in my windows service, so that I cannot save the values from memory to the external file.
Is there any event provided by framework to handle those kind of killing process or is there any Win API providing those events to handle in windows service.
Anyone facing these situation please give me a response....Thanks in advance....

Handle the Application.ApplicationExit event.
Note that this will only get triggered if the user uses the "End Task" button on the Applications tab. The "End Process" button on the Processes tab will not trigger this event.
This is because EndTask allows the app to run any clean up code itself. EndProcess is to kill totally unresponsive processes. You can't get round this. You have to accept that the user always has overall control of their PC and if they want to kill your app without letting it clean up they can. Windows does warn that killing processes can cause undesired behaviour. (Just think, the user could just pull the plug out from the socket which would give your app no time to clean up)
I would suggest writing the data out periodically (say every 10 minutes) and save a timestamp with the data so you know when it was saved. Then, when the service is exited correctly, write out a little bit of information at the end of the file that says "Service exited correctly" or something that means that. Then, when your service starts up, look for the "Service exited correctly" message. If it's not there you know the service was terminated unexpectedly, so you can warn the user. If you stored a timestamp with the saved data you can tell the user how much data was lost etc.

Thanks for the response and help...
But I am still thinking that atleast operating system will get a notification that the said process is going to kill now or it is getting killed. So in that way, any API can provide those handling of killing. As you said saving data periodically will is one way we can achieve max data and if the EndProcess is having such a limitation, my requirement is still pariall.
So if you get further more info plese keep me posted....
Thanks again Simon.
