Firing a DataGridView.Sort() on an unbound column generates an error.
Try use a bound column which is used to calculate the unbound one and fire the sort on that column. If you do not have one, create a dummy one.

I'm able to connect to a pop3 email using the tcpclient and i'm also able to get the email, i'm having problem when someone send me an attachment like an image or a .doc file. How can i decode the attachment from the email and save it to my computer?
|
|
|
|
|
I think you should consider using regular expressions to identify the image / doc or whatever comes with the mail.
You will however need to read some rfc's before starting ...
|
|
|
|
|
I can do the regular expression since the email tells you what type of mime is, and what is rfc's? do you have any example that I can follow?

You don't.
Use the window.status property in Javascript to set the text of the status bar.

This should be an easy on but I can't seem to find the answer. How do you return the index of an item selected by a user from the ListView control?
Thanks
|
|
|
|
|
.SelectedIndices[0]
/ravi
|
|
|
|
|
Thanks, this works but when the first item in the listview is selected I get the following.
InvalidArgument=Value of '0' is not valid for 'index'.
Parameter name: index
???

That implies no item is selected. Try this (intentionally verbose) example:
int GetFirstSelectedItem
(ListView theListView)
{
int nIndexOfFirstSelectedItem = -1;
SelectedListViewItemCollection selectedItems = theListView.SelectedItems;
if (selectedItems.Count > 0) {
ListViewItem firstSelectedItem = selectedItems[0];
nIndexOfFirstSelectedItem = firstSelectedItem.Index;
}
return nIndexOfFirstSelectedItem;
}/ravi

Thanks, it seems that the problem was I was checking the index when the SelectedIndexChanged was fired. Whenever I made another selection I would receive the error. I switched the code to the Click event and now it works fine.
Thanks for your help

Hi every body ,
(sorry for my english...)
Suppose we have a text box (textBox1).
If we "leave" this text box by pressing the TAB key, the order of the following events is:
textBox1_Validated
textBox1_LostFocus
But, if we leave this text box using the mouse, that is by pressing on another control on the Form using the mouse, the order of these events is:
textBox1_LostFocus
textBox1_Validated
This is strange behavior in my opinion.
May anyone explain me this behavior?
Thanks in advanced, elaj

When you change the focus by using the keyboard, focus events occur in the following order:
- Enter
- GotFocus
- Leave
- Validating
- Validated
- LostFocus
When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:
- Enter
- GotFocus
- LostFocus
- Leave
- Validating
- Validated
There is nothing strange in that, is it?

Hi SkyWalker,
There is nothing strange if your code does not depend on it.
However, i wrote a code that that register to control's "LostFocus" event and do some job there.
If the user call some other method - i unregister the event handler, but it should be done only after the "LostFocus" occurred.
Because the the user traditionally will call my method in the "Validate" event, you may understand why this behavior raise some problems.
However to overcome it i do the following:
I registered to the "GotFocus" event, and within this event handler i registered to the "LostFocus" event.
When the "LostFocus" event occurred, i do my job and unregistered the handler when it completed.

I have a simple question with no doubt a complex answer. What I am trying to achieve is to check LAN for machines (mostly Workstations but could be windows xxxx Servers among them and find which ones are running a particular Service.
Is there a relatively easy way of doing this? What sort of security measures could get in the way? The service I'll be searching for will does export a remoting interface.
Any pointers would be greatly appreciated.
Happy programming!!

One way could be using
<br />
[DllImport("MPR.dll")]<br />
public static extern UInt32 WNetEnumResource(IntPtr hEnum, ref Int32 lpcCount, IntPtr lpBuffer, ref UInt32 lpBufferSize);
Some code example[^]

When you design a form in Visual Studio 2005, you may put a control in form and set properties of this control. After you did this, Visual Studio will insert codes to XXX.designer.cs automatically. Even the control is a Third-Part control, Visual Studio can do the same thing.
So, my question is how to do the thing by ourselves ?

By not doing it in the designer. If you want to control the property completely, create it in your form's load event, and add it to the forms Controls collection.

You can write the code by yourself.. declare objects and initialize them in InitializeComponent() (run the method in constructor) if you want them to be available at design time or in OnLoad event if you want them to be created at runtime.
vs designer uses *.designer.cs files (and keyword 'partial') to separate it's code from yours. so the file isn't needed.
