. Net Program excel export method can be described everywhere. however, it is only the export of some data. versions, formats, and locations are generally not considered. and word export. this may not be frequently used. word operations are indeed a little harder than excel operations. here, the younger brother collected some information. I wrote a demo. it seems suitable for use in the development process. the core code below will be shared with you. The project first references a component Mic

Studio generates an InterOP assembly for the project that might not work fully in all cases. for more information, see troubleshooting in office at run time.

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:

operation may cause exceptions and exchange temporary copies with the original object; 3. The Terminator, dispose () method, and the target method bound to the delegate object should ensure that they do not throw an exception under any circumstances. 46. Minimal interoperability 1. There are three costs for interoperability: Data enumeration costs between managed and unmanaged stacks, and switching costs between managed and unmanaged code, development work for developers dealing with hybrid

The GNU program, also known as the slave program, was publicly launched by Richard Stallman on September 27, 1983. Its goal is to create a set of completely free operating Systems. It has made a standard for the GNU C when writing Linux. ANSI American national standards association, the standard ANSI C standard that it made to C was later accepted by the Internat

1. Introduction C ++ language was originally created as "a better C ", however, this does not mean that the compilation and connection methods used by global variables and functions similar to C in C ++ are the same as those in C. As a language to be compatible with

This article is about how to invoke C (c + +)-written DLLs in a C # environment. "Reprint marked the source." First, the preferred creation of a C DLL project, production DLL files used for standby, steps are as follows: 1, VS2010 create C + + Project Select Win32 Applicatio

In recent projects, project source code confidentiality issues are involved, because the code is written in C #, easy to decompile, so the decision to extract the core algorithm part of the use of C + + writing, C + + so far seems to have not been very good decompile, of course, if you are a disassembly master, perhaps it is possible to decompile. This means that
