C # To C ++ -- C # The Path to C ++ Transformation (1) C It takes a lot of determination to study full-time. Some people may say why they don't study while working. Indeed, everyone has their own path. I chose to move to the bottom layer of technology and quickly. Therefore

It's actually the old post of a previous blog. If you haven't written a blog for too long, paste it. Since max9, maxscript can directly call. Net DLL files and create classes to use the methods. And. Net can call the DLL file written in C ++. Therefore, you can use C # to encapsulate the C ++ code and call it in Max. The following is an example. --------------- B

After reading [C # | Excel] by the farmer's uncle, I accidentally remembered a small project I created two years ago, I have encountered this strange problem that the Excel process cannot end. In fact, the solution is very simple. Excel is a very special thing, all operations on the resource are exclusive, so it is necessary to strictly release the resource. In order to better communicate with you and help those programmers who are being confused, I w

under the Java.util.zip namespace. Zip files and C # I want to use ZIP compression in an application written in C #. Unfortunately, the Microsoft.NET Framework does not currently contain any classes for manipulating Zip files. However, I did find several products related to Zip compression. For example, #ziplib (formerly known as Nziplib,http://www.icsharpcode.net/opensource/sharpziplib/default.asp) is

C ++ introduction source code Concise version, C ++ entry-level C ++ learning, the difference between C ++ and C is worth knowing, the source code is known C ++ introduction source code brilliant version,

C language is process-oriented, and C + + is Object-orientedThe difference between C and C + +:C is a structured language that focuses on algorithms and data structures. The design of the C program is primarily concerned with the

interfaces, developers can write custom RCW and manually map the types provided by the COM interface.. NET Framework compatible type. Use comimport to reference COM componentsCom InterOP provides access to existing COM components without modifying the original components. Using comimport to reference COM components often involves the following issues: 1. Create a COM object. 2. Determine whether the COM interface is implemented by an object.

adds a reference to the interop assembly, you can use the. NET application to create an instance of the various types contained in this assembly (that is, the COM wrapper object), the method invocation (or access to its properties) of those objects will be forwarded to the COM component.To debug word, for example, you might often need to write code like this before c#4:Object WordApp = new Word.Application

Set the support for the Common Language Runtime Library to "Support for the Common Language Runtime Library (/CLR )" Program code: #include "stdafx.h"#include "stdio.h"#using "../debug/AddDll.dll"using namespace AddDll;int _tmain(int argc, _TCHAR* argv[]){ int result; Add ^add = gcnew Add(); result = add->iadd(10,90); printf("%d",result); scanf("%

COM objects have been the basis of Windows Programming for many years. It is inevitable that the existing COM objects still need to be used during the transition to. net. "Interoperability encapsulation processing" is a packaging process. When you move parameters and return values to or from a COM object, in this process, these parameters and returned values are packaged as equivalent data types. The Common Language Runtime Library exposes COM objects by calling the runtime callable wrapper (RCW

Recently, in a project, the customer requested to display the content in the generated RTF file by page. As he had no idea about this, he also found relevant information on the Internet, in addition, I used my own search on msdn to solve the problem. The following is a simple summary of C # Word documents (encryption, decryption, and pagination). I hope to help some friends. Pai_^ Before writing code, you need to reference the corresponding DLL file:

unmanaged stacks, and switching costs between managed and unmanaged code, development work for developers dealing with hybrid environments; 2. Using the blittable type in InterOP can effectively replicate back and forth in hosted and unmanaged environments without being influenced by the internal structure of the object; 3. Use the in/out feature to ensure the most appropriate and unnecessary multi-copy, and improve performance by declaring how da
