Here's my scenario:
I want to create a report with a header, details and footer where each of these sections come from a separate typed dataset.
So, for an invoice I want to do the following:
header - client info
details - line items for order
footer - totals for order
I can't go directly to the database with Crystal, so I thought using typed datasets would be OK.
I can create a header report and a line item report with separate typed datasets, but can't come right with one report composing of three typed datasets.
To create one report I'm using:
CrystalReport1 report1 = new CrystalReport1();
report1.SetDataSource(lines); //lines = a typed dataset
crystalReportViewer1.ReportSource = report1;
For the composite report, I've tried:
dsCompo.Tables.Add( lines.Copy());
dsCompo.Tables.Add( companytx.Copy());
CrystalReport4 report4 = new CrystalReport4();
report4.SetDataSource(ds);
crystalReportViewer1.ReportSource=report4;
But the viewer jsut asks for a database login...
I have tried using a subreport, but get the same result.
Is there something obvious I'm missing?
Cheers,
Simon

Same question as above, just after 2 cups of coffee:
Here's my scenario:
I have report A populated with a typed dataset and it works.
I have report B populated with a different typed dataset and it works.
Now I want to combine these 2 into another report.
Using the Crystal.NET designer, I make a new report and add the above 2 subreports.
Given the following code:
CrystalReport4 report4 = new CrystalReport4();
report4.SetDataSource(/* ??? */);
crystalReportViewer1.ReportSource=report4;
What do I set the datasource of my composite report to?
I really need to pass both populated typed datasets in, but the interface is a little unhelpful...
Cheers,
Simon

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;
newTimer.Tick += new EventHandler(TheMethod);<br />
<br />
<br />
newTimer.Start();

By the way this will solve it:
Tuliplanet wrote:
this.Opacity = this.Opacity + 5;
Change it to
this.Opacity = this.Opacity + 0.05;
You should use numbers between 0 to 1.

see my reply!!
i set interval=100,but the form just show after a flash!

Hehe.. Easy man. Didnt see that sorry.
Anyways.. You could also use Thread and ThreadStart?
<br />
using System.Threading;<br />
<br />
<br />
ThreadStart ts = new ThreadStart(TheMethod);<br />
Thread t = new Thread(ts);<br />
t.Start();<br />
<br />
<br />
public void TheMethod(){<br />
for(int i = 0;i<=100;i++){<br />
Thread.Sleep(10);<br />
}<br />
}<br />

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;
