Base Address Proprty - C# / C Sharp

Steve Guidos

We are writing a set of Windows Services using C#.NET that will run on the
same server. One of the developers here said that we should assign each
service its own Base Address using the Properties page, so that the services
won't conflict with each other. I cannot seem to find any information about
when to set the Base Address or what its practical effect would be. My
impression is that the BaseAddress is just a "suggested" base address, and
that Windows / .NET will check it but load the .dll where it thinks is best
if there is a conflict.

Is setting the Base Address something that we should do? What is the
practical effect of changing that parameter?

Steve,

The Base Address that is suggested by VS.NET is random (from what I can
tell). VB6 defaulted to a fixed address, which required the DLL to be
remapped by the OS for the process when it was used.

However, if they are the same, the loader will take care of the mapping
for you, there will be no conflict. Having different base addresses just
makes it faster (by how much depends on the size of the assembly).

Also, since these are separate services, the point is moot, since they
each have their own address space.

Hope this helps.

How Do I Prevent Copying From Base Class?

by: Bryan Parkoff | last post by:

I find an interesting issue that one base class has only one copy for each derived class. It looks like that one base class will be copied into three base classes while derived class from base class is executed. It means that three derived classes are pointed to a separated copy of base class. I do not allow second and third copy of base class to be created, but it must remain only first copy of base class. It allows three derived...

Passing derived class object array in place of base class object array

by: justanotherguy63 | last post by:

Hi, I am designing an application where to preserve the hierachy and for code substitability, I need to pass an array of derived class object in place of an array of base class object. Since I am using vector class(STL), the compiler does not allow me to do this. I do realize there is a pitfall in this approach(size of arrays not matching etc), but I wonder how to get around this problem. I have a class hierachy with abstract base...

For most users, this new feature is actually very convenient. If you want to control the update process,...
