Windows表单应用程序与DLL链接 [英] Windows form application linking with DLL
问题描述
我在c ++中有一个Windows窗体应用程序（vs2015）。我想将DLL链接到这个应用程序并使用dll函数。
我有一个类库项目（.dll）
// test.h //标题文件
#include" test1.h" //使用的结构在这里定义
命名空间测试
{
class Class1
{
public：
static int write（WRITE_TEST writetest）;
};
}
// #include test.cpp
#include" test.h" ;
命名空间测试{
int Class1 :: write（WRITE_TEST writetest）{
//实现。
}
以上代码构建为DLL。
<我有一个Windows窗体应用程序。我在这个表单应用程序中添加了上面的dll作为参考。还包括其他包含目录中的dll路径。
#include" test.h"
&NBSP;测试::的Class1 ::写（writetest）; //从dll调用函数。
但我得到的错误是未解析的令牌（0A000499）public：static int _cdecl test： ：Class1 :: write（struct）。
从DLL调用函数时有什么遗漏？

还包括其他包含目录中的dll路径。
为什么这样？附加的include目录属性告诉编译器
在哪里查找其他头文件。 （与#include语句一样。）

Hi,
i have a windows form application(vs2015) in c++. i want to link DLL to this application and use dll functions.
i have a class library project(.dll)
//test.h //header file
#include "test1.h" //structures used are defined here
namespace test
{
class Class1
{
public :
static int write(WRITE_TEST writetest);
};
}
//#include test.cpp
#include "test.h"
namespace test{
int Class1::write(WRITE_TEST writetest){
//implementation.
}
Above code built as DLL.
i have a windows form application. i added the above dll as reference in this form application. Also included the dll path in additional include directories.
#include "test.h"
test::Class1::write(writetest); //calling function from dll.
but i get the error as unresolved token(0A000499) public:static int _cdecl test::Class1::write(struct ).
Anything am missing for calling the function from DLL?

Also included the dll path in additional include directories.
Why do that? The additional include directories property tells the compiler
where to look for additional header files. (As in #include statements.)
