Try something like this:
using (System.IO.StreamWriter sw = new System.IO.StreamWriter("test.txt",false))
{
foreach(object o in this.comboBox1.Items)
{
sw.WriteLine(o.ToString());
}
sw.Close();
}

The sw.Close call is redundant, the "using" statement automatically closes the StreamWriter when control reaches the end of the block.

Yup, I know this is true for the StreamWriter (and should be for any class implementing the IDisposable interface).
I just can't get rid of the habit to be on the safe side.
And sometimes i have something like this:
using (x)
{
using(x.y)
{
x.Close();
}
}
by calling the x.Close i simply free the resource as soon as i do no longer need it, not as soon as the finally of the using statement is reached.
And finally you never know if the IDisposable.Dispose actually does implement all the stuff you expect it to contain.
OK, your are right... it is redundant  (but i still have my points!)

Hmm. Just for the sake of argument,
using (x)
{
using(x.y)
{
x.Close();
}
}
After all, that's the sole purpose of the using statement

hi
can anybody help me to see if a certain item exists in a drop down box?
thank you
|
|
|
|
|
Use the Contains function on the drop down box's Items property. Like
...
bool isItemPresent = comboBox.Items.Contains(itemToBeFound);

Which one? It would be easier to help if you said what exactly that error says. (with stack trace if possible!)

You don't. If your drpSelected.Items contains array of string, than it works. If it does not, item text (displayed in control) are result of item's ToString() method. Now think about it. What Contains method need to find your item? It must be able to say if some item from items is (equals) to item you are searching for. So, in order to make THIS example work, you can a) have only strings in drpSelected.Items (so Contains will compare string references) or b) override Equals() method for items or c) if( drpSelected.Items.Contains( item ) ). First option seems to be best, but then again we have no idea what your code *really* means.
[edit]
or you can create new item (e.g if( drpSelected.Items.Contains( new item(lblID.Text) ) ) )+ override Equals(). But that sounds quite stupid
hmmm it looks like your drop has something to do with IDs? I suspect your Item have properties Item.UserName and Item.ID, right? Don't you need only selected one? Than use SelectedValue instead of SelectedText. (you must fors say what is Value "column" -ListControl.DataValueField Property[^] )
[/edit]
Does it help?

Where can i find a good article about c# and exchange server. I need to programmically delete email in a particular mailbox and other possible functions.
Please help
|
|
|
|
|
|
Ohh ... i just review your link and i don't think that would be my purpose. My application will send a email into serveral mailboxs and if those users click a submit button on that emails and successfully postback to the server page, these emails has to be automatically removed (controled by my script) from their mailboxs .
I know there are so many DLLs and implementation i can use, such as WebDEV, CDO, or etc, but i need a good starting point ...
Thannk you

In the System.Windows.Forms.UnsaveNativeMethods class (which is marked as internal) it is defined as:
[DllImport("user32.dll", CharSet=CharSet.Auto)]
public static extern IntPtr DefWindowProc(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);
If you define it just like this you can use it in your own code.

why if i add this row:
[DllImport("user32.dll", CharSet=CharSet.Auto)]
i get a compile error.
What do i have to specified to the compiler?

You probably get a "DllImport" not found (or the like) message.
Simply add this line to you file:
uses System.Runtime.InteropServices

er... actually it should be using 
It is somwhat differnt from the uses clause in pascal.
Using is simply telling the compiler to try to prefix the namespace for any non local symbol.
The Pascal uses equivalent in C# is the References section in your solution.
Btw. my I ask why you need a call to the DefWndProc in C#?
What kind of subclassing strategy are you up to? I have not yet entered any scenario where i would like to call the DefWndProc directly since it is completely encapsulated by the framework.

of course, i'm overring some windows message to avoid to draw the form title bar as unactive.
It is just a hard stuff

Shouldn't something like this do the magic?
<code>
protected override void WndProc(ref Message m)
{
const int WM_NCPAINT = 0x0085;
if (m.Msg == WM_NCPAINT)
{
m.Result=(IntPtr) 0;
return;
}
base.WndProc (ref m);
}
the base.WndProc(ref m) calls the DefWndProc then...
