Hi,
I know that you can add a Form to another Control (e.g. a Form) by setting its TopLevel
property false; I have no idea if that is possible in Visual Designer itself tho.
Not sure how useful it would be either, if it has to be part of a Form right from the start,
why make it a Form first?

It´s not useful, i don´t need it! 
I only wanted to know how is done. I saw it in some applications and it looks nice!
|
|
|
|
|
I wish to do something along the lines of:
MyObject theObject = new MyObject();
DumpObject(theObject);
...
elsewhere...
public void DumpObject(Object obj)
{
string name = GetName(obj); // <<--- This is the part I'm missing
System.Console.WriteLine("The name of the object is " + name);
// this will print out:
// "The name of the object is theObject"
}
I thought I could use reflection to get the name of the object but I'm not having any luck. I know this must be possible, but I'm stumped.
TIA,
Jeff

how you can get object name if it doesn't have Name property  , or you just want to know its type?

No, I can't assume that the object has a Name property, and I don't want to know the type (which I'd just do Type t = myObject.GetType()).
I'm developing a (generic) debugging routine, so if I passed a variable named someObject:
MyMethod(someObject);
...at runtime I want to get "someObject". I'd like to, and I'm sure there is a way, but I'm not seeing how to do it.
Thanks though,
Jeff

Hi Jeff,
1.
you are confusing objects with references. An object can have a name (say you provide a Name property),
a reference only refers to the object.
Also there could be many references to the same object.
How about
MyObject theObject=new MyObject("Paul");
MyObject anotherReference=theObject;
DumpObject(anotherReference);
Now which name would you want to get?
The only one you will be able to get is "Paul" provided it got stored somewhere *inside* the object.
2.
It is however possible to get the name of the reference itself, using reflection.
But then you have to pass the reference itself, hence something like:
MyObject theObject=new MyObject("Paul");
MyObject anotherReference=theObject;
DumpObject(ref anotherReference);
Now DumpObject gets hold of anotherReference itself, and through reflection should be able
to get at its name. Haven't done this though, when names are important I store them inside the
object.

With the above code, I'd want to get the string "anotherReference" inside of DumpObject(). If the code was DumpObject(theObject), I'd want to get the string "theObject" inside of DumpObject().

That's the part I'm not able to do.

No, it's not possible. An instance of an object doesn't have a name, neither has the reference to it.
The variable holding the reference does have a name, but that is not passed along to the method, neither is a reference to the variable. Also, unless the assembly is started with debug information, I don't think that you can even get the name of a local variable.
There might not even be a variable holding the reference. Consider these examples:
Here you have no variable at all:
DumpObject(new MyObject());
Here the variable is just a member of a KeyValuePair structure in a dictionary:
Dictionary<int,MyObject> MyDictionary = new Dictionary<int,MyObject>();
MyDictionary.Add(42, new MyObject());
DumpObject(MyDictionary[42]);
What would you imagine that the name should be; "Value", "42" or "MyDictionary"?
Despite everything, the person most likely to be fooling you next is yourself.

Right.
What was I thinking again?
so only solution is to put a Name inside the object, and forget reference names altogether.
|
|
|
|
|
But then, what's the name of the Name? 
|
|
|
|

.NET 4.0 is rumored to provide introspection for that very purpose.
|
|
|
|
|
That's cool, but I can't wait that long. For now what I'm going to do is something like:
DumpObject(theObject, "theObject");
Thanks,
Jeff

OK.
FYI: There used to be a little preprocessor trick to automate that in C and C++ (using some ## magic),
but that is not available in C#...

Hi, do you want to acess a object from a form in otherform?

I have wrote a few projects in c# now, but in my latest I have come across a problem I can not seem to figure out. I have a float input from my user, lets say its something like
float t = 29;
I need c# to recognize and treat this float as 29.0 and be able to display it as such.
How do you control precision in c#? Thanks for the help!

Hi,
there is nothing wrong with float t=29;, but you could also write
float t=29.0f; to make it more explicit.
When outputting, use ToString() with a format specification argument if you prefer to be in charge
of the details.

Thanks a lot! Its always the small differences between c# and java that seem to trip me up. Such is the learning process. I appreciate it!
|
|
|
|
|
You're welcome.
How is this different from Java?
|
|
|
|
|
to display float in string form use yourFloatVariable.ToString("nx") where x is your precision

Ah thanks a lot, its those little ones that get me. Thanks!

Is there a way to create pure C# remote processes and capture StdOut ?
I am able to do this by calling PsExec.exe (from sysinternals) from Process class and capturing Stdout.
I need an elegant way, Can Process class also create remote processes?
Can System.ManagementObject call capture StdOut apart from creating remote processes?
Thanks in anticipation

Hi,
the Process and ProcessStartInfo classes hold what you need.
MSDN contains a simple example, where stdout (not stderr) is captured, and becomes available
only when the EXE terminates. Using extra threads and some Stream methods can overcome these
two limitations when necessary.

Oh I still could not find that link..could you please forward the remote process article.
Thnaks!

Well i was happily coding away when i launched the debug process and ms started throwing exceptions. (and it was working fine about 5 secs before)
Application.StartupPath is throwing a SecurityException
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Why now?

Make sure your project doesn't have partial trust security settings enabled.
In Visual Studio, you can go to your project properties and click on the Security tab to discover this information.
