I did this under 32bit XP without any problem.

I don't have a clear idea regarding how to handle 32bit under 64bit OS.

Actually, I found it.

For C#, Managed C++ and native C++, all target platform/machine are x86.

The native C++ is used as a static library.

Yes, that is one thing I tried to do. I am able to set target platform for both C# and managed C++/CLI, but I did not find Target Platform option for native C++ progects.

Hi, All,

I am trying to expose functions in native c++ through managed c++/CLI to C#. when I set the Target platform to "Any CPU", I got the error

Unable to load file or assembly,....
...

Yes, it works. However, i still don't understand why the compiler stops searching the base class for a method called foo() when it sees one in the derived class. It is not intuitive to me, although...

Hi, Lindley,

Thanks for your quick reply.

foo(a, b) is also a pure virtual function, which will be defined later in another class, say, E. If I explicilty tell D to call B::foo, will it invoke...

Hi, Folks,

I have pure virtual class questions:

class B
{
public:
virtual double foo(int a) = 0;
virtual double foo(int a, int b) =0;
}

Thanks.

Here is the constructor I have:

InitializeComponent();

this.FormBorderStyle = FormBorderStyle.None;
//this.Opacity = 1;
this.CenterToScreen();...

Hi, All,

I am trying to create a splash window using a modeless window. The dialog template is built as usual and is displayed by calling Show() instead of ShowDialog() as for modal window. The...

I am using stl library.

I observed that four thread is slower than one single thread and I am trying to figure out why?

Suppose one thread accesses the first part of a vector and another thread operates on the second part of the vector.

If the vector can only be accessed by one thread at a time, one thread has to...

If a vector is synchronized, will multiple thread be more efficient than a single thread?

What is other alterative to a vector in the context of multi-thread?

Thanks,

Arjay,

Four threads read the same std::vector through iterator, but they are not overlapping, say for example 0-1000, 1001-2000, 2001-3000 and 3001-4000.

Vector is synchronized, does this mean...

Hi, All,

I tried to use multiple thread to speed up. Unfortunately, it becomes about 10% slower if I add one more thread, although exactly the same code is used in both cases.

I am sure my...

Hi, All,

My .Net assemlly, which depends on Microsoft.Office.Interop.Excel.dll, is not working. I want to test if Excel can load the right version of this supporting dll. Is there any way to load...

yes, I call a Native C++ member function from Managed C++ to get a member variable, a vector of double.

Hi, All,

I am trying to call a native C++ function from managed C++, which is supposed to return a vector of double. Unfortunately, it is always empty in release mode, although it works under...

Hi, All,

I made a automation add-in for MS Excel.

If I calculate a cell calling a function from the COM by return, it generates a VB error:

Can't find project or library.

However, it...

Hi, Gurus,

I am trying to build a .net assembly using C#. Within this assembly, some other .net assemblies provided by Microsoft as well as some third party .net assemblies and COMs are used. It...

Hi, Gurus,

I have a C# COM Addin used in Excel. I want to display some texts in the Excel status bar from C#. Any one has any idea of how to make it?

Thanks in advance.

Hi, Peter,

Thanks for your help.

I cannot agree with you. Since "A a" only declares a local variable in some function, the classs will not be instantiated until "A a;" is executed at running...

Actually I could not reproduce the problem in another context.

I am using Excel + COM + Managed C++ + Unmanaged C++. I cannot post a small piece of the code to reproduce the error.

What I am...

Here is the context of the problem:


I have a base class

class B
{
public:
virtual bool fun() =0;
}

Hi, all

I am running into a very interesting problem, which has been bothering me for a while.

I have a base class

class B
{
public:
virtual bool fun() =0;
