Hey...

Like this:

this.WindowState = System.Windows.Forms.FormWindowState.Minimized;

I have a function with a problem as describe in it:

public void Func(Control control)
{
   // If control is actually a Form object, do this
   ...

   // Else if control is a Button object, do that
   ...
}

I need to know at runtime, whether the control object is actually derived from Form or Button. Any ideas?

public void Func(Control c)
{
if (c.GetType().ToString() == "System.Windows.Forms.Form")
{
}
else if (c.GetType().ToString() == "System.Windows.Forms.Button")
{
}
}

Or you could make it look nicer by

public void Func(Control c)
{
     if(c is System.Windows.Forms.Form){
     {
    
     }elseif(c is System.Windows.Forms.Button)
     {


     }
}

Crystal reports with multi typed datasets

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

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 | :)
