EagleTool.h

#ifndef _EagleTool_H_
#define _EagleTool_H_
class EagleTool {

  public:
    void static extractCorrectPathofEagle();

 };

#endif

EagleTool.cpp

#include "stdafx.h"

#include "EagleTool.h"
#include "Form1.h"

void static extractCorrectPathofEagle(){

}

Answer 1

您需要在定义中包含类名：

static void EagleTool::extractCorrectPathofEagle() {
    // ...
}

否则，您将定义一个完全不相关的函数，该函数碰巧具有相同的名称。

visual studio windows从另一个类调用函数
