How to create a fadein dialog by C#?

I'm not sure if you can use multiple DataSets, but you could merge one typed DataSet with the other and use that. In order to design the report, you might consider creating a typed DataSet that has the merged structure. If you don't want to keep the generated classes for it in your project, you could probably toss it after you're finished designing your report since the merged DataSet would have the same structure.

Change the Opacity property of your form in a timer or something like that.

it doesn't work!

the interval property of timer is 100!

this is my code,is there anything wrong?

private void button1_Click(object sender, System.EventArgs e)
{
this.Opacity = 0;

timer1.Start();
}

private void timer1_Tick(object sender, System.EventArgs e)
{
this.Opacity = this.Opacity + 5;

if(this.Opacity >= 100)
{
timer1.Stop();
}
}

Hey.. You have to set the timers interval, when it has to run the method.

Timer newTimer = new Timer();<br />
newTimer.Interval = 1000; // one sec<br />
newTimer.Tick += new EventHandler(TheMethod);<br />
<br />
// ..<br />
<br />
newTimer.Start();

By the way this will solve it:

Change it to

this.Opacity = this.Opacity + 0.05;

You should use numbers between 0 to 1.

Hehe.. Easy man. Didnt see that sorry.

Anyways.. You could also use Thread and ThreadStart?

<br />
using System.Threading;<br />
<br />
//..<br />
<br />
ThreadStart ts = new ThreadStart(TheMethod);<br />
Thread t = new Thread(ts);<br />
t.Start();<br />
<br />
// ..<br />
<br />
public void TheMethod(){<br />
 for(int i = 0;i<=100;i++){<br />
  Thread.Sleep(10);<br />
  // Perform Code<br />
 }<br />
}<br />

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

How to convert Virtual-Key code to char?

5-Feb-04 21:33

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?

Changing the X and Y properties of a point

6-Feb-04 2:42

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; //Compile time error, Why?
p.Offset(1, 0);//I don't no why it dosn't work?
p = new Point(13, 14);//The only way I got through

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.

Sure!

I am actually in this situation:

I store some instances of Point structs into an ArrayList, then I have a lot of these ArrayLists each of which is stored in one main ArrayList, so for changing the X position of all points, I iterate through all of them within 2 ArrayLists.

Heath Stewart wrote:

Sure, the 2 ArrayLists are defined globally in my class, and I don't pass them as parameters.

Anyway, I can send you my source code later if needed,
and I really appreciate your answers Heath! Rose | [Rose]

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.
