Visual Studio .dll Reference not found ?

I had never had this error before, and I didn't move any file, or exclude any reference. I'm getting this error (link). In the ajaxcontroltoolkit.dll.refresh file, I get a path to the DLL, but it is a path that was located in someone else's computer (who no longer is in charge of this). It might as well work if I just re-do the refere...

Third-party DLLs in a website layout

I have a solution with several projects and one website. The website uses some third-party DLLs. I have to place the DLLs in the bin folder under the website. This is the same bin where the DLLs from the other projects get auto-loaded. Is there a way I can place the third-party DLLs in a separate folder? If I 'Add Reference' to the DLL ...

latex table reference

Hi, I wrote a long table with a label in a tex file and \input it into my main tex file. The reference in the main tex file to the table, however, does not show the numbering of the table but the one of the next table that are written directly in the main tex file. All long tables that are written directly in the main tex file have corr...

.NET Reference "Copy Local" True / False Being Set Based on Contents of GAC

We had a very interesting problem with a Win Forms project. It's been resolved. We know what happened, but we want to understand why it happened. This may help other people out in the future who have a similar problem. The WinForms project failed on 2 of our client's PCs. The error was an obscure kernel.dll error. The project ran fine o...

Cleaning up a dynamic array of Objects in C++

I'm a bit confused about handling an array of objects in C++, as I can't seem to find information about how they are passed around (reference or value) and how they are stored in an array. I would expect an array of objects to be an array of pointers to that object type, but I haven't found this written anywhere. Would they be pointers,...

C++ Implicit Conversion Operators

I'm trying to find a nice inheritance solution in C++. I have a Rectangle class and a Square class. The Square class can't publicly inherit from Rectangle, because it cannot completely fulfill the rectangle's requirements. For example, a Rectangle can have it's width and height each set separately, and this of course is impossible with ...

We say Reference are const pointers. Why I am able to assign a new variable to ref B? The below program compiles successfully.

#include<iostream.h> int main() { int a=10; int &b=a; cout<<"B"<<'\n'<<b; cout<<"A"<<'\n'<<a; b=100; cout<<"B"<<'\n'<<b; cout<<"A"<<'\n'<<a; int c=20; b=c; cout<<"C"<<'\n'<<c; cout<<"B"<<'\n'<<b; } ...

C++ is there a difference between assignment inside a pass by value and pass by reference function?

Is there a difference between foo and bar: class A { Object __o; void foo(Object& o) { __o = o; } void bar(Object o) { __o = o; } } As I understand it, foo performs no copy operation on object o when it is called, and one copy operation for assignment. Bar performs one copy operation on object o when it is ...

Adding a reference to a class library or service from a smart device project in VS.Net?

We're trying to debug a WCF service that is being consumed by a smart device project. The problem is that the service never gets debugged, only stepped over. Similarly, when trying to add a class library to a smart device project, the following error is seen: Cannot add a reference to a desktop project from a smart device project. An...

Does GC guarantee that cleared References are enqueued to ReferenceQueue in topological order?

Say there are two objects, A and B, and there is a pointer A.x --> B, and we create, say, WeakReferences to both A and B, with an associated ReferenceQueue. Assume that both A and B become unreachable. Intuitively B cannot be considered unreachable before A is. In such a case, do we somehow get a guarantee that the respective references...

Wondering about a way to conserve memory in C# using List<> with structs

I'm not even sure how I should phrase this question. I'm passing some CustomStruct objects as parameters to a class method, and storing them in a List. What I'm wondering is if it's possible and more efficient to add multiple references to a particular instance of a CustomStruct if a equivalent instance it found. This is a dummy/exampl...
