Any reasons C/C++ programmers steer away from enums? All I ever see is defines...
Hey leppie! Your "proof" seems brilliant and absurd at the same time. - Vikram Punathambekar 28 Apr '03

This is actually bad practice in C++. You should use const declarations instead.
const int DIALUP = 0;
or enums, as another poster has suggested.
The #define in C# is for conditional compilation. And it should be used like this in C++ also.
See, for example, Scott Meyers's "Effective C++"

Hi, i'm starting C#, and i have a problem:
I'm developing a application that should open one "window", which should be created from a form that has buttons, like a menu selector. When i click the button it should open a new especific form, e.g. button 1 opens form1; button 2 opens form 2 ... That i can do, but i want to open it in the same "window", not openning a new window with my new form, an when i hit a save button i want to go to the previous form.
Can´t it be done???
thank for your time.

It looks like a MDI app[^].

It sounds like you want to create an MDI application. This gives you one main window while allowing you to open various child window applications. One of the authors on here wrote a cool little tutorial that should help you out.

Its funny you say that, because I posted a question similar to that just a little while ago, here are a couple of solutions for you:

S. Rod gives you a great solution, I give a simple one.
Good luck, its titled form design quandries.
Good luck,

Instead of using MDI, you could create all of your "forms" as user controls and just handle their loading/unloading on the same form

Could you please send me a small example?

It's more easy to use a panel in form and you cant make him on run-time
like this . In the dinamic construction the bad point is that the RAM is more use that for static declaration , but the diference is very small .
in Click event of the window make the code
{
Panel p=new Panel();
//give Panel properties
this.Controls.Add(p);
}

Depending on the amount of unmanaged versus managed code you want to expose :
- expose C# classes as COM type libraries. More info here[^].
- use MC++ mix mode. More info here[^].

I don't see your point. Owned windows are not like modal windows. That is, controls in owner windows continue to respond to mouse events even if an owned window is active. In other words, owner window/owned windows are exactly behaving like palettes versus main windows. The only slight difference is the window caption which changes from highlighted to unhighlighted when you click on one window and then on another.
If you are having problems with that caption, just hide it by applying the appropriate window style to it (remove WS_CAPTION). How this is done is through Interop SetWindowLong. Just look at a post 2 days ago, where I have the C# code to do something similar.
Hiding the caption can also be combined to making a form behave like a tool window (WS_EX_TOOLWINDOW), ie like a floating toolbar. But this won't change much since, as I have already said, owner/owned forms are not even modal against each other.

Hi WiB,
thank you for your answer, but this is not really what I want. Is there a Com-Object or anything else to communicate with serial-Ports??? I haven´t found anything in my Toolbox.
