In MultithreadingProgramUsing COM objects in is really a headache. When you can access an interface pointer, it does not mean that you can call methods on the interface. I have never really understood several thread modes of COM. The problem is that when I tried to call a COM interface method in a thread and this

register the COM + managed component. Regsvcs.exe uses the following properties to publish the component as a SOAP endpoint and server (out-of-process) activation on the server: [Assembly:applicationactivation (Activationoption.server, soapvroot= "Cssoapsql")] This component uses a different transaction in each method invocation, has an automatic completion method, and is configured to buffer. When using managed and unmanaged

. When the com you write is to be submitted to "others", you must process the assertion failure. 4. Write some macros that can be "lazy. If a component has many attributes, and the processing of attributes is just to directly access member variables, writing a lot of get and put functions is a little annoying. These functions look almost the same, but the types of accessed data are different: Get func

Then write the client program to call it. Place a dcomconnection in the client program, connect to the write COM + server above, place a clientdataset, set its remoteserver and provider proper

Because a COM component can only be used on Windows, the program must be run on a Windows server. In the local XP system installed on the installation of no problems, installed on the server Win2003, encountered n a problem, finally, or Gump classmate shot to solve, a full toss of not less than 10 hours to finish. After installing the latest 12012 version of the WPS Office Personal Edition, it is logically finished, but the running program reported e

can contain one or more apartments. Sta means that the apartment can only contain one thread.MTA (multi threaded apartments ). This apartment can contain multiple threads.The biggest difference between STA and MTA is that MTA can use all the shared resources in the same apartment to execute multiple threads concurrently. While multiple Stas can share data, but cannot execute threads concurrently, there is a performance problem. Specific Search: sta mta. Single- Threaded apartmentsa process h

the standard interface of OLE. Because OLE already provides standard interface proxy and stub components, the automation object can be run in the DLL component, you can also run it in the EXE component. In a distributed environment, automated objects can be created or connected by remote customers. 3. attributes and Methods Methods and properties are two basic features of automated objects. Methods refer to the functional services provided by automated objects, and properties refer to the dat

The greatest "invention" of Microsoft in the last decade is probably counted as COM (Component Object Model. In the sophomore year, I have been using. Net for Windows development.ProgramThe operation of the Set (assembly) is much simpler than that of the COM operation, and. Net can also interoperate with the original COM. It is reasonable to say that you can ski

The most vexing problem with developing COM + applications is how to debug COM + components. Because COM + is performed in COM + 's execution Environment, Delphi programmers cannot, like Delphi's distributed multi-tier application system, set breakpoints for application servers directly in the Delphi IDE to debug. In

Guangzhou Asian Games officially held only more than 250 days, the construction of the Asian Games has entered the final stage, in order to allow the Guangzhou Asian Games to become the largest Asian Games in the history of one of the biggest games, Guangzhou from all walks of life muster the energy to carry out the final sprint. With the close of the Asian Games, the various topics related to Guangzhou and the 2010 Asian Games have become the focus of public attention. One of the most notewort

http://danadler.com/jacob/ What is Jacob? The "JACOB is a" java-com bridge "allows" to call COM Automation components from JAVA. It uses JNI to make native calls into the COM and Win32 libraries. The JACOB project started in 1999 and are being actively used by thousands of developers. As a Open-source project, it has benefitted from the combined experience to the

From: http://blog.163.com/junby2004@126/blog/static/9714233120091105308843/ People familiar with object-oriented programming and network programming must be familiar with ActiveX, Ole, and COM/DCOM concepts, but the relationship between them is still vague to many. The difference between components and objects should be clarified first. A component is a reusable module that consists of a set of processing

, jstring, jint ); Step 3: Compile Windows DLL (using vc6.0)First, I want to write a Windows DLL using MFC or SDK. In order to access COM more conveniently, I used MFC in my example and used part of ATL, however, you can actually use the simplest SDK method. 3.1: generate the api dll frameworkA: Use the VC Wizard to generate a DLL in the MFC mode (Note: it is a conventional DLL and cannot be extended)B: Def

Summarize the code implemented in this article into a single project. At present, it is only implemented to an intermediate stage, focusing on the implementation principle of COM interface, and does not include the part of the class factory. In the future, we need to add advanced functions such as plant. File composition: Ifoo.h COM interface IFoo, interface ID iid_ifoo declaration file. outside.c

How to read and write data from the COM port of the device through SerialPort The SerialPort class is used to control serial port file resources. It provides synchronous I/O and event-driven I/O, access to pin and interrupt status, and access to serial driver attributes. In addition, the SerialPort function can be encapsulated in the internal Stream object, acces

Basic Principles of connectable objects and connection points In order to provide greater interaction between the component object and the customer, the component object also needs to actively communicate with the customer. The Component Object communicates with the customer through the outgoing interface. If a component object defines one or more output interfaces, this component object is called a connectable object. The so-called outbound interface is also a

successfully use ServicedComponent remotely, you will also need to use the Gacutil.exe or. NET Framework user interface to put this compiled assembly into the global Assembly cache (GAC). To access this SOAP endpoint through WSDL, use the following VBScript: Set c = GetObject ("SOAP:WSDL=HTTP://LOCALHOST/CSSOAP/CSSOAP.CALC.SOAP?WSDL") For i = 1 to 10 WScript.Echo I "" C.add (i,i) "" Time Next As a simple example of SOAP interoperability, SOAP T

wireless routers are increasingly unable to meet user needs. Recently, IP-COM has launched a new suitable for home users, cost-effective W641R11N wireless router. W641R is based on the latest IEEE802.11n standard. The wireless network transmission distance is more than six times that of common 802.11g products, and the transmission rate is more than three times that of common 802.11g products. Backward compatible with the IEEE802.11b/g standard. This

This time I was thinking about how to use a small program with COM components. I suddenly remembered why I used com during the last interview, instead of using a common DLL? After checking it on Google, many people also asked the same question: using COM to write a program is more troublesome than using a common DLL, but it brings a lot of benefits, especially wh
