The original thought is not to use the. def file in the DLL, and add __declspec (dllexport) adornments directly before the function that needs to be exported. But when it comes to exporting stdapi __declspec (dllexport) DllGetClassObject, Just prompt"warning C4518: "__declspec (dllexport)": Unexpected storage class or type descriptor encountered here; ignored"(I'm using vc.net.2003).

#ifndef, (or #ifndef), #def, #endif等宏这几个宏是为了进行条件编译. In general, all lines in the source program are compiled. However, sometimes it is desirable to compile a part of the content only if certain conditions are met, that is, to specify the conditions for the compilation of some content, which is "conditional compilation". Sometimes, you want to compile a set of statements when a condition is met, and then compile another set of statements when the condi

In a task completed last week, I found a bit confused: When writing C ++ DLL for VB call, the def file must be used to define the export symbol. OtherwiseProgramFailed to link. We all know that the def file is used to prevent the C ++ compiler from renaming the function. Another alternative to achieving the same effect is to use the extern "C" identifier. If the DLL is called by C ++, C #, Java, and so on

Use def to export a function from the DLL, or use the _ declspec (dllexport) command to export a class from the DLL, which is familiar to everyone and often used. Here we will introduce Use the def file to export a class from the DLL. The specific principle or why is it not nonsense? Learn How to export and try again. The procedure is described here. 1. Open vc6.0 and create a "Win32 dynamic-Link Library" p

In Python programmingProgram, Which can be defined using functions. The basic form is: Def Function Name (parameter 1, parameter 2 ,......, Parameter n ): Execution statement The name of the function is called, and the parameter is the input parameter, which can be defined or not.#Example 1: simple function usage#Coding = gb2312#Define functionsDefHello ():Print'Hello python!'#Call a functionHello ()>>> Hello python! A function can contain pa

It can be said that def defines a module variable, or a variable of a class. It is itself a function object. The function that belongs to an object is the property of the object. Of course, you can also call it "method".Python's functions differ greatly from those of other languages. It can be overridden by other variables, such as: def func (): print 1 print func () #1 func = 5

def, refers to definition. Is the definition of a function. Define the time functions, functions do not execute, they are prepared for calculusVal, refers to value. is a phased outcome of the calculation. The part to the right of the equal sign is evaluated to a value, no matter how long. It can be said that a Val is a small computational process. Val is the smallest program unit in which the function is programmed.var, refers to variable. Their value

When you declare variables within a function definition, they are not related to other variables with the same name outside the function, that is, the variable name is local to the function. This is called the scope of the variable. All variables are scoped to their defined blocks, starting with the point where their names are defined.Using local variablesdef func (x):Print (' x is ', x)x=2Print (' Changed local x to ', X)X=50Func (x)Print (' x is still ', X)OutputX is 50Changed local X to 2X is
