Assuming you are using VS .NET 2003, Right click on the Project in Solution Explorer, click Properties, go to Common Properties->General, you'll find an entry for Application Icon.

Convert to int but....

Sasuko3-Jul-05 0:49

3-Jul-05 0:49

I would to convert to int a number got by a division of two doubles....
For example 500/900 i get 0.555... that is converted using Convert.ToInt16() in 1.
I would get 0 instead, then 1 if i divide 900/900 or 970/900.
How can i do?

Perhaps you are looking for the Math.Round function?

Math.Round just convert a double value to the nearest one, i need to convert it to the littlest one,
example:
1,43 to 1
1,21 to 1
1,98 to 1
2,01 to 2
2,54 to 2
8,76 to 8
5,99 to 5

ok? How can i do?

You are talking about the Floor function (returning nearest LOWER integer):

<br />
double a = 1.43;               // a = 1.43<br />
int    i = (int)Math.Floor(a); // i = 1<br />

Similar function is Ceiling, it returns a nearest higher integer ( Math.Ceiling(1.43) = 2 ), just for curiosity.

Have you considered Math.Floor()?

ShowInTaskbar causes Alt-Tab icon to disappear

Check out the pasted code. When the app starts, you can hit Alt-Tab and see the colorful icon in the Task Switching window. Now check the box and hit Alt-Tab again. We are left with a different icon.

The actual application I am working on has an Icon that appears on the exe and in the top-left of the form, but when ShowInTaskBar goes false, the Alt-Tab icon goes from the icon I designed to some default icon.

Any ideas?

If you compile that code, you'll see that there is an icon (albiet some default icon) that represents the Application when you hit alt-tab and see the task switcher come up. This icon has three colored boxes.

Now, see what happens when you go back to the application and uncheck the check box. Hit alt-tab again, and you see some new icon representing the application. This new icon looks like an empty Windows form with a blue border on the top. My question is: What happened to the other icon with the boxes? I only posted a test program to show this; my actual program has icons every place I need them, except for alt-tab when ShowInTaskBar is false.

Do you have a reference to System.Drawing in your project?

yes i have included System.Drawing as a namespace..

S. Senthil Kumar3-Jul-05 3:35

The System.Drawing namespace is spread across multiple assemblies. You need to explicitly add a reference to System.Drawing.dll.
