Did you try all three types of timers?

System.Timers.Timer
System.Threading.Timer
System.Windows.Forms.Timer

Sounds like somebody's got a case of the Mondays

Hi All,

I have created one project and have installed on GAC. After that I am not able to "debug" my code. Could you please help me to resolve my problem.

Exactly saying, I have created one IE toolbar. That assembly, I have kept it in GAC. But, I am unable to debug that assembly.

Thanks in advance

Thanks and regards,
Srinivas

Why not just remove it from the GAC?

Datagridview: got the row value now need the string value

I know a lot of people ask how to get the row index value in a C# datagridview so this code should help them. But I am now stuck.

The data source is created on the fly and is destroyed as soon as it is viewed so I have to retrieve data from the visible datagrid view:

I need to get the string value of my known (row, column). Googling and going through the IDE has been no help. How do I do this?

int i = adObjectDataGridView.CurrentRow.Index;<br />
MessageBox.Show(Convert.ToString(i));<br />
//adObjectDataGridView.//need string value of known row, column

if you know row# = i, and column# = n, try:

adObjectDataGridView.Rows[i].Cells[n].Value.ToString()

EventHandler for Child Form Closed Event?

alanteigne10-Dec-07 8:31

10-Dec-07 8:31

In my project I've created an instance of a custom form class. In my form class, I have error detection that simply closes the form if an un-handleable error occurs. Due to the nature of the app, this is the desired behavior. However, I would like an event on the main form to fire off whenever this happens. How can I do this?

I initialize my custom for like this:

frm_myForm myForm = new frm_myForm();

For any other control I want to add a handler for, I would do something like this:

btnShowForm.Click += new System.EventHandler(btnShowForm_Click);

... and create the corresponding function. I applied similar logic to my form instance but it doesn't seem to work that way. (myForm.Closed += new blah blah). Am I missing a key concept here? It seems like this would be functionality used all the time so I fear I'm being dense and not seeing the big picture. Any advice is appreciated...

Alan

Look at the performance counter component. It can do all the things you're asking for.

Here's a little bit of help, pulling code from something I wrote a while back:

add this reference...
using System.Diagnostics;

create a perf counter...
private PerformanceCounter cpuCounter;

define it
cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total", true);

get the value:
cpuCurrValue = Convert.ToInt32(cpuCounter.NextValue());

I created a myPerfMon class that uses the perf counters to get and return the values, and another class that tells it to do so on a timer.

Reading registry values

I am trying to get the Computer's name in the registry under
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\ComputerName\ComputerName
with the following:

string strCompName = (string)Registry.LocalMachine.GetValue("SYSTEM\\ControlSet001\\Control\\ComputerName\\ComputerName\\ComputerName");

But I am getting a null value.

BTW I did search the forum, but every post I clicked on from the query sent me to the main forum page.

Thanx in advance!

Figured it out. I thought that RegistryKey.CreateSubKey() would create values, but it reads the subkey.

This can be accomplished in an easier way:

Environment.MachineName will return the computers NetBIOS name. (If that's what you're looking for).

So far I got it working!

Do you mean event handler?

If I have understood your question, you're asking if it is possible to call a method from an event handler, right? Well, the answer is yes. You just type the name of the method within the event handler, then it will be called every time that event is triggered.

private void timer1_Tick(object sender, EventArgs e)
{
    SomeMethod();
}
