The problem is not with thread or timer. He set the wrong value for that property.

I have a xml document with utf-8 encoding and tags name is on cyrilic. I can't use XPath to find a tag. What can I do?
10x in advance

What do you mean by I can't use XPath? You get error you don't know the proper query string? There are many samples article about XPath in this site and some thers in MSDN too. Have you take a look at them?

I'm using KBDLLHOOKSTRUCT.vkCode and need to get char
|
|
|
|

You should just be able to cast it to a char:
char c = (char)theStruct.vkCode;

Point p = new Point(12, 14);
....
p.X = 13;
p.Offset(1, 0);
p = new Point(13, 14);

Are you sure you're typing an upper-case X and not a lower-case x? The latter is a private field and thus only accessible from the Point struct itself. Assigning the former (upper-case X) is fine.
Also keep in mind that the Point struct (like all structs) is a value type. If you think you have a reference to it somewhere else and you didn't pass it using the ref keyword, then you're mistaken. If you pass Point as a param you pass a copy, not a reference. If you're expecting Offset to change that, it won't. Otherwise, it does modify the instance of the Point on which it was called.

First of all, there is no "global" anything in .NET. If doesn't matter if these ArrayLists are instance or static members, the problem is that the Point struct is a value type and a statement such as
((Point)myArrList[i]).X = 13; is actually compiled to something similar to this
Point p = (Point)myArrList[i];
p.X = 13; Either way, therein lies the problem. Since the Point struct is a value type, you're actually making a copy of it (in p in this example), not assigning a reference to it. This is how value types work. It doesn't matter if you pass them as parameters or store them in a list. When you get them from the list you are getting a copy so the value type in the list will not be changed.
See the article, Value vs Reference Types in C#[^] (actually, all of .NET) for a comprehensive discussion of the topic.

I just read the article, it was really informative...
But now there is a very big question in my mind:
Where should I store my Point structs so that be able to change their X and Y properties later, without requiring to reNEW them?

You don't have to re-instantiate them, only re-add them to the ArrayList (or collection, or class member, etc.):
Point p = myArrList[i];
p.X = 13;
myArrList[i] = p;

Set the URL to a URL like http://host.domain.tld/dir/file.mp3. Download the Windows Media Player SDK[^] for nearly completely API documentation.

Hi, I need to use a form control but without the round-edged windows title bar. Does anyone know how to get rid of the title bar. Anyway, I'm using C# in this Windows application. Thanks.
|
|
|
|
|
Set the ControlBox property to False and the Text property to blank.
|
|
|
|
|
You can also set Form.FormBorderStyle to FormBorderStyle.None.

...which makes it really cool for use as a "splash" window, among other fun things you can do with a borderless form...

Hi,
I have functionality already implemented in double click event of ListView. Now I want to add a button that would do the same, but instead of writing everything for that button click event, I just want to fire the ListView Double Click event !
How can I achieve this ?
Thanks,
Paul

My suggestion is that you write another method and call that method from the Click and from the DoubleClick. Something like this:
private void listView1_DoubleClick(object sender, System.EventArgs e) {
someCommonLogic();
}
private void someCommonLogic() {
MessageBox.Show("Hello World!");
}
private void btnSharesMethod_Click(object sender, System.EventArgs e) {
someCommonLogic();
}
private void button1_Click(object sender, System.EventArgs e) {
listView1.Items.Add("Item" + (listView1.Items.Count + 1).ToString());
}

I know there is a PerformClick for button, is there something not like that for other events ?
|
|
|
|
|
My understanding is that PerformClick exists essentially so that keyboard actions like "ESC" and "Enter" can invoke a button. In general terms, I believe you are looking for more information on Events and Delegates. In other words, you can define your own events and methods with the correct signature that are "bound" to those events as handlers. Although somewhat complex, there is documentation in MSDN and the .NET Framework to understand how you can pursue this further. You might try this[^] as a starting point.
