The T-SQL programming language of SQL Server is powerful in data storage and recovery, but is less functional in terms of interaction with systems outside of the SQL Server database. However, we can overcome this limitation with SQL Server's built-in COM automation environment, which enables users to automate COM objects in stored procedures.
With 7 extended stored procedures in SQL Server 7.0 and SQL Serve
PHP can operate COM and DCOM object 1 under the Win32 platform. I created a DLL to compute something. Is there any way to run this DLL in PHP? 2. What does ' unsupported variant type:xxxx (0XXXXX) mean? 3. Is it possible to manipulate visual objects in PHP? 4. Can I put COM objects into session? 5. How do I capture COM errors? 6. How do I generate DLL files in PH
In my daily work, I have seen many COM codes written by different developers. I was amazed by the many creative ways of working with COM, and some of the clever code that made COM work might not even have occurred to Microsoft. Also, seeing some mistakes repeated again and again made me frustrated. Many of these errors are related to thread and security, and this
The object-oriented idea is difficult to adapt to this distributed software model, so the idea of componentized programming has developed rapidly.
According to the idea of componentized programming, complex applications are designed into small, single-functional component modules that can run on the same machine, it can also run on different machines.
In order to implement such an application, some extremely detailed specifications are required between the build program and the build program. On
first, the basic knowledge of COM components introduction:
1, what is COM
COM is a Microsoft set up a component of the specification, the purpose is to achieve the reuse of components, whether you are in C, DELPHI, VB what language to write, as long as the observance of this specification is COM components, can be inv
The problem starts with this: I need to write a COM + to connect to different databases. Some friends might say that you should build a COM + for each database, but not in my system. We are doing an education-assisted system, the user is a school (including school teachers, students, parents), we build a database for each school, these databases are the same structure. Of course, we also have a management d

COM functions built into PHP4 are quite attractive for us to develop programs in the Win32 environment, but there is still not much relevant technical documentation. This article will deal with MS office Word, Excel, and Adobe Distiller in three examples to illustrate how to use COM functions in PHP.
COM technology was presente
. NET technology is the next-generation platform technology that Microsoft vigorously promotes. Since the formal release of. NET Technical Architecture Beta2, this technology has gradually become mature and stable. According to Microsoft's platform system occupancy rate, we can easily imagine that in the next year or two. NET technology is bound to become a mainstream technology platform, and the most important premise for a new technology platform to develop rapidly is: he will not abandon the
In addition to providing back-compatible,. NET Framework also supports forward compatibility, which is meant to be exposed. NET assembly is possible for COM utilization. Now let's see how we can get COM to leverage. NET assembly.
Calling. NET assembly from COM
Now let's look at the principle of using. NET assembly from COM
Com is the abbreviation of Component Object Model.
What kind of software products do users need? This is a multi-choice question, but it is highly efficient and robust. How can a software developer meet users' needs? Ensure that the backward compatibility with previous versions is not damaged during application upgrade. System services must be extended without a specific operating system. Object-orientedProgramDesign is obviously a revolution
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.

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

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

At the same time, Sohu it is exclusively informed that the company's business has been reorganized within 51.com.

Although COM technology has not been recommended by Microsoft, I still have a simple record of how to debug a COM component.
It's almost like debugging a normal DLL, a little different.
1. Creating COM components
Now use vs to create COM components is very easy, can use c++/vc++ or C #, indifferent C # to write
New Year's high trading continues. COM domain name again lead the coquettish
2009 out of the sight of people, ushered in 2010 years, in this old year, the domain name transaction also brought good luck. Digital Domain name 1199.com in Christmas Eve to 230,000 sold, the world's tallest high-rise caliph sent a high 160828.com domain name 160,000 of the price, and
In this article, we will discuss the following questions:
• Create a simple COM object using C # (using COM's interop attributes).
• Access COM from VC + + client software. The client software uses the TypeLibrary (. tlb file).
For simplicity and convenience for developers to use and test, we used the Northwind database in the default installation of SQL Server database software.
