Ok, after three C# books, (C# How to Program, Programming in the Key
of C#, and C# Weekend Crash Course) and three weeks, I believe I have
tried everything to make a certain form function correctly. I am
trying to learn C# after playing around for a bit with procedural
programming with PHP, not OOP, and believe I have learned quite a bit
in three weeks, just not enough to accomplish this one task.
If anyone has a bit of free time and wants to impress the hell out of
me, I would love to get this problem behind me. Thanks to Jon a few
weeks back for giving me some direction, and I tried to get it
running, but to no avail.
Specifics:
1) Form is part of an MDI app developed in VS 2003 Architect
2) Form basically calculates the speed an engine operates based on
certain parameters the user enters. (gear sizes, roller circumference,
max rpm, etc.)
3) Results should calculate each time a variable has been changed by
the user, preferably without the user clicking a calculate button.
4) This is the part the gives me the headache: Results need to be
sorted in a textbox, or possibly a listview with columns, but that's
not a necessity, sorted by engine speed(mph) or ratio, either one, and
each ratio and gear combination need to be listed as well. Example of
one line:
Gears Ratio Speed
15/21 1.400 75.47
....next line, etc....
If you view the form, it will hopefully make better sense. Also,
currently, the form blows up if you select anything except and engine
first. I can fix that, but just have not since I have been trying to
get the results sorted in the textbox.
Looking forward to whatever help is received ...sorry, no prizes :/
Thanks,
Mark

No. There are two methods of adding a custom component:
1) (The recommended way)
Add a reference to the project the component class is in (if it's a separate
project), THEN, go to the toolbox and right click on it, go to add/remove
items, browse, find the DLL the component class is in, and select it. You
should then have an icon representing your new component, which you can then
drag onto your form.
2) (The quick way - good for if the component class is in the same project
as the main exe)
Add a standard listbox to your form, and then go into the code listing,
expand the 'component designer generated code' region, and replace
System.Windows. Forms.ListBox with the name of the custom listbox-derived
component I gave you (there should be two instances - one where it's
declared, one where its instantiated). Then build the project. If it builds
OK, switch back to the form designer view and it should update itself.

Thanks for the reply.
Added the component class using the 2nd method you mentioned. I
then...
replaced this:
private System.Windows. Forms.ListBox listBox1;
with this:
private McLb listBox1;
and replaced this:
this.listBox1 = new System.Windows. Forms.ListBox() ;
with this:
this.listBox1 = new McLb();
Error when debugging:
....\multilistb ox.cs(8,21): error CS0246: The type or namespace name

Still having difficulty implementing the custom component class ...:(

Added the component class using the 2nd method you mentioned. I
then...
replaced this:
private System.Windows. Forms.ListBox listBox1;
with this:
private McLb listBox1;
and replaced this:
this.listBox 1 = new System.Windows. Forms.ListBox() ;
with this:
this.listBox 1 = new McLb();
Error when debugging:
...\multilistb ox.cs(8,21): error CS0246: The type or namespace name
'ListBox' could not be found (are you missing a using directive or an
assembly reference?)

No. There are two methods of adding a custom component:
1) (The recommended way)
Add a reference to the project the component class is in (if it's a separate
project), THEN, go to the toolbox and right click on it, go to add/remove
items, browse, find the DLL the component class is in, and select it. You
should then have an icon representing your new component, which you can then
drag onto your form.
2) (The quick way - good for if the component class is in the same project
as the main exe)
Add a standard listbox to your form, and then go into the code listing,
expand the 'component designer generated code' region, and replace
System.Window s.Forms.ListBox with the name of the custom listbox-derived
component I gave you (there should be two instances - one where it's
declared, one where its instantiated). Then build the project. If it builds
OK, switch back to the form designer view and it should update itself.
any problems post back

Wow, can't wait to get to that point in my C# travels ...after three
weeks, I'm at a level of confusion where I understand 10% of it 90% of
the time and 90% only 10% of the time :)
I'm having a bit of difficulty implementing the Component Class. I
added it to my project, but not sure how to call it. Would it be
something like:
new ListBox(mCurren tCounter, mCurrentAxle, mRatio, mMph);
Thank you so much for the time.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
