hi,

ok i have 3 files

target.exe, sample.dll, injector.exe

the target.exe has a code something like these..
int a = 2, b = 3, c;
a + b = c;


and the injector.exe has also a code like this..
int c = 5;


after my injector.exe inject the sample.dll to the target.exe
i want to send int c = 5(from injector.exe) to the target.exe. (How?)

Solution 1

Define a Property(get set) for the private member c.

Then you can set the property using reflection. Let Property Name is "PropForMyC"

private int c;
Public int PropForMyC
{
get {return c;}
set {c = value;}
}


Suppose you have your Target.exe has an object(class) that has the above mentioned Property. Let this object be obj
Now you can use like this :
PropertyInfo prop = obj.GetType().GetProperty("PropForMyC", BindingFlags.Public | BindingFlags.Instance);
if(null != prop && prop.CanWrite)
{
    prop.SetValue(obj, 5, null);
}



Thanks,
