Hi,
I would like to find out how I can run a Windows Service by pressing a key on the keyboard.
My idea is to create a Windows Service in C# and when the user press the Print Screen key the service must capture the screen and save the image.
Thank you!!

hi
I want to list out the drives on my device. i wrote this code for .net compact framework:
string[] dList = System.IO.Directory.GetLogicalDrives();
for (int i = 0; i < dList.Length; i++)
{
MessageBox.Show(dList[i]);
}
But on compilation i get the error saying that "System.IO.Directory.GetLogicalDrives()" is not supported.
Can anyone please help.
Thnaks

All the devices/platforms are not supporting this method. Please make sure that your device is supported by Compact framework.
You can go through this[^] link for that.

I have a treeview, when it has many items, then the scrollbar automatically appears, but it always
scrolls to the end item by default, how to force it to scroll to the start position by default?
thanks.
|
|
|
|
|
The scroll position will be determined by the selected item in the tree view. After loading the treeview make the first node as the selected one.
like
if (treeView1.Nodes.Count > 0)
{
treeView1.SelectedNode = treeView1.Nodes[0];
}

Hi,
I want to enable a menu, which is in main class, against any child class function but it is not activating.
Instead If I enable it against any button of main class it becomes enable.
as here udb-main is main class and from its button of start I open another form like:
private void bstart_Click(object sender, EventArgs e)<br />
{<br />
<br />
UserLogin uslog = new UserLogin();<br />
<br />
uslog.Show(); <br />
}
Now in userlogin class login button I want to active main class activities menu against successful login.Here just relevant code is:
<br />
private void bLogin_Click(object sender, EventArgs e)<br />
{<br />
<br />
DialogResult ds;<br />
ds = MessageBox.Show(" you are successfully login ","Login Success", MessageBoxButtons.OKCancel);<br />
if (ds == DialogResult.Cancel)<br />
this.Close();<br />
else if (ds == DialogResult.OK)<br />
{<br />
udb-main hmain=new udb-main();
hmain.activitiesToolStripMenuItem.Enable=true;<br />
hmain.hessloadfunc();<br />
this.Close();<br />
} <br />
<br />
}<br />
plz tell me how I can enable/disable any control from another class.
Thanx.

You have to assign the parent class to the hmain field instead of assigning a new instance. Most probably it has to be
udb-main hmain = (udb-main)this.Parent;// Main class.
BTW the architecture which is changing the state of a parent element does not seems to be good.

There is a small change required in both of the functions, we can use Owner instead of Parent
private void bstart_Click(object sender, EventArgs e)
{
UserLogin uslog = new UserLogin();
uslog.Show(this);
}
and
else if (ds == DialogResult.OK)
{
udb-main hmain = (udb-main)this.Owner;
hmain.activitiesToolStripMenuItem.Enable=true;
hmain.hessloadfunc();
this.Close();
}
Please try this.

Now I am working with webservices.But now we are facing a problem while calling a method in webservice asynchronously from a web page.ie.when the webmethod computes the result it will not get reflected in the webform, because the page would be rendered to the client while the method processing data.Please help me to avoid this problem( without using polling)...........

Did it occur to you to read the documentation? Look at the DateTime class.

System.DateTime moment = new System.DateTime(
1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;
// Month gets 1 (January).
int month = moment.Month;
// Day gets 13.
int day = moment.Day;
// Hour gets 3.
int hour = moment.Hour;
// Minute gets 57.
int minute = moment.Minute;
// Second gets 32.
int second = moment.Second;
// Millisecond gets 11.
int millisecond = moment.Millisecond;

I doubt you will be work around this because it's more of a security feature. I use it all the time to verify what link I am actually clicking on, since what's displayed has nothing to do with the underlying link.
For example, http://www.apple.com
Take care,
Tom
