Hi Paul,
I am sure it is not related to memory alignment: double alignment is not
more relaxed than float alignment. If there is any difference in performance, one
should have a look at actual code (assembly rather than MSIL); it could prove
Colin's guess is right.

Hmmm, I think I might just write up a quick little app to do a fun little weekend investigation

Nothing really outstanding at this point. Seems to be a push between the two.

But, that is just my guess.
It's correct that the processor does all operations internally using doubles. Which ever type is faster also depends on several other factors, though. If you for example process an array of numbers, floats may be faster than doubles just because more of them fits in the processor cache.

Hi
for floating point operations Double is the most efficient type because those operations are optimized by hardware.

thank you all.
look at these codes
1.
for(int i=0;i<100000000;i++)
{
float f1=i/357;
float f2=i/546;
if(f1>f2/3454)
{
f2=f1;
}
}
2.
for(int i=0;i<100000000;i++)
{
double f1=i/357;
double f2=i/546;
if(f1>f2/3454)
{
f2=f1;
}
}
the first code consume 7.27 sec and second code consume 6.73 sec in my computer.
of course assignment statement is high time consumer.
somebody has any idea about it?

I have a user-defined control which has as a child control a TextBox (.NET 3.0). When I call Focus() on this TextBox, it doesn't work. However, if I add a MessageBox.Show() line, and then call Focus(), it does indeed Focus on the TextBox. I'm not sure what is happening here - focusing on a different control, and then on the TextBox, doesn't seem to produce the same effect. Can anybody point out my (probably obvious) mistake?

Try to call Focus() on the user control first. Where did you add the MessageBox.Show() line?

The code is like this:
<br />
LineControl newLineControl = GetControlForLine(newLine);<br />
MessageBox.Show("try now"); <br />
newLineControl.Dialogue.Focus();
I tried adding newLineControl.Focus() before newLineControl.Dialogue.Focus() as suggested, but it didn't make a difference.
I tried logging when each control gets and loses focus, and got the following result when clicking on a LineControl (my user control):
TextBox got focus
LineControl got focus
..then away from it:
TextBox lost focus
LineControl lost focus
This was the same regardless of whether the MessageBox.Show() line was included, yet when that line is included, newLineControl.Dialogue.Focus() works, and when it isn't, it doesn't. Any ideas? Very confused.

What part do you not have any idea with? Is it the datagridview part or the Excel Office Interop part ( I am assuming this is how you are going to do it )?

You are not very clear. If you want to run another .exe from an .exe, you can use the Process class.

Well, you...
1. take the input that the user has given you.
2. hash the password (because you are using hashed passwords, right?)
3. call a stored procedure that looks up the user and compares the hashed passwords. This will return a true/false back to to the application.
4. If the password is correct you allow them to continue
5. If the password is wrong you repeat the process or exit the application.
If you want more detail on any of this you have to show where you got stuck. If you take a different design descision you have to tell us what that is.
