Actually, that should be:
ftemp = 0.0 - ftemp;
The value 0 is an integer value. You should use a double value to make sure that your value doesn't get converted to an integer before the calculation.
The zero value is superflous, though:
ftemp = -ftemp;

b { font-weight: normal; }

Just to be pedantic, the integer value (0) would be widened to a double value (0.0), not the other way around.

You've got to be kidding me!! I find it interesting to see the miriad of solutions people come up with for such a simple problem. But DAMN, the performance and memory implications of this one, in a high-use situation, are just sickening!! Good job!!

yep. Apparently there are people with so little knowledge of math, they didn't realize a simple -1 multiplication would swap the sign.

Yeah, I'm feeling that pain too! I'm dying to get my hands on the SP, but causiously. It seems every other SP that comes out breaks more than it fixes...

Or so little knowledge of the language that they don't realize that there is a negation operator that is specially made for just changing the sign of a number.

Hi!
I have a problem, if i have a treeview which is filled with allot of TreeNodes and for some reason i need to restart the treeview, can i restart it to the same visible mode that it was before, i mean if i opened node one and its chield and its chield, and now i restart it, i mean create it again can i visibly show the same childs as it was before the restart, this is of corse when the treeview does not change.
Thanks

You can, but there's no magic way to do this. When you clsoe the TreeView, record the node hierarchy and each node's expanded state. When you want to restore your nodes, you'll have to do this manually based on the information you previously recorded.

Hi.
I want to catch the audio from modem when somebody calls my computer by phone.
i.e that must convert the analog sound that arrives to modem, to digital in the form that I can get it.
Now I can establish a call via modem commands.
I prefer that do this in managed code in c#

First, you need to get the data out of your database. To do that, use ADO.NET. If you have an ADO.NET-specific question, ask in the ADO.NET forum[^].
Once you've got your data out of the database, you can provide a constructor that takes an integer for each form you want to pass:
class MyForm : Form
{
public MyForm(int integer)
{
...
}
}
You can then construct it like
MyForm form = new MyForm(5);

hello Judah Himango
i know how to connect to database
and i know how to open form with parameter
the probelm now if i want to generate button on form load what i must do to get parameter 5 on Click on the second button ...

Let me make sure I'm understanding. You want to get parameter 5 once the button is clicked?
To generate a button from code and listen for a click event:
Button b = new Button();
this.Controls.Add(b);
b.Click += new EventHandler(OurClickHandler);
...
void OurClickHandler(object sender, EventArgs e)
{
}
Does that answer your question?

Hi,
I have a Typed DataSet that is bind to some winform controls. TextBox, Labelx etc....
At some point, my dataSet values are updated being the scene. The probleme is that my binded controls are not updated automatically when DataSource is updated.
What I have to do to force the rebind of my controls ?
