打算写一个C++程序 其实我是想用MFC静态库实现一个通过TXT配置文件在程序中动态创建界面的程序。
主要思路是：
1：提供一个基类CSearchBaseDialog，在基类中，程序从配置文件中读取界面控件的信息，然后根据配置文件中的信息在界面上创建相应的控件。
配置文件的格式：
IDC_BTN_MAIN_MENU=10;80;10;40;102;button;菜单
解释：
IDC_BTN_MAIN_MENU=left;right;top;bottom;nID;controlType;TEXT
即：
IDC_BTN_MAIN_MENU=x坐标;y坐标;top坐标;bottom坐标;控件句柄数;控件类型;控件文本
现在对代码进行了重构:
1:stdafx.h的代码:
#ifndef STDAFX_H_
#define STDAFX_H_
#include <afxwin.h>
#include <afxext.h>
#include <afxdisp.h>
#include <afxdtctl.h>
#include <afxcmn.h>
#include <windows.h>
#define MFC_SHOWWND 0x04EF
#endif
2:读取配置文件的类:
const int ITEM_COUNT = 500; // 文件数目
class MFCINi
{
public:
MFCINi();
virtual ~MFCINi();
public:
/**------------------------------------------------------------------------------------
* 名 称: <Open>
* 说 明: <打开配置文件>
* 参 数: <MFCINi &ini>：<配置信息对象>
* <const CString &strPath>：<配置文件路径>
* 返 回: <true：打开成功；false：打开失败>
*---------------------------------------------------------------------------------------*/
bool Open(MFCINi &ini, const CString &strPath);
/**------------------------------------------------------------------------------------
* 名 称: <Close>
* 说 明: <关闭文件，释放占用的内存>
* 参 数:
* 返 回:
*---------------------------------------------------------------------------------------*/
void Close();
/**------------------------------------------------------------------------------------
* 名 称: <Read>
* 说 明: <根据配置键，取得配置项>
* 参 数: <char* item>：<配置键>
* 返 回: <读出的配置信息>
*---------------------------------------------------------------------------------------*/
char* Read(char* item);
/**------------------------------------------------------------------------------------
* 名 称: <GetAppPath>
* 说 明: <取得应用程序的路径（bug路径）>
* 参 数: <CString &strAppPath>：<存储取得的路径的字符串>
* 返 回: <配置项的值>
*---------------------------------------------------------------------------------------*/
static void GetAppPath(CString &strAppPath);
char **m_chItems; // INi文件配置项
char **m_chItemValues; // 项目值
int m_nItemCount; // INI文件总配置项数
private:
FILE *m_pf; // INI文件指针
};
该类的实现:
#include "stdafx.h"
#include "MFCINi.h"
//////////////////////////////////////////////////////////////////////
// Construction/Destruction
//////////////////////////////////////////////////////////////////////
// 取得应用程序的路径
void MFCINi::GetAppPath(CString &strAppPath)
{
GetModuleFileName(NULL, strAppPath.GetBuffer(MAX_PATH), MAX_PATH);
strAppPath.ReleaseBuffer();
int nLength = 0;
char ch = NULL;
ch = '/';
nLength = strAppPath.GetLength();
strAppPath = strAppPath.Left(nLength - 1);
nLength = strAppPath.ReverseFind(ch);
strAppPath = strAppPath.Left(nLength + 1);
}
MFCINi::MFCINi()
{
m_nItemCount = 0;
m_chItems = NULL;
m_chItemValues = NULL;
m_pf = NULL;
}
MFCINi::~MFCINi()
{
Close();
}
// 打开文件
bool MFCINi::Open(MFCINi &ini, const CString &strPath)
{
CString strIniPath;
CString strAppPath;
MFCINi::GetAppPath(strAppPath);
strIniPath.Format("%s%s", strAppPath, strPath);
m_pf = fopen(strIniPath, "a+");
if (m_pf == NULL)
{
return false;
}
m_chItemValues = (char**)malloc(ITEM_COUNT*sizeof(char**));
m_chItems = (char**)malloc(ITEM_COUNT * sizeof(char**));
for (int i = 0; i < ITEM_COUNT; i++)
{
m_chItemValues[i] = NULL;
m_chItems[i] = NULL;
}
char chReading[500];
char *pchSeparator = NULL;
while(m_nItemCount < ITEM_COUNT)
{
int nEOF = fscanf(m_pf, "%s ", chReading);
if (nEOF == EOF)
{
// 读取成功
return true;
}
pchSeparator = strstr(chReading, "=");
int nCharCountName = pchSeparator - chReading;
if (nCharCountName < 0)
{
continue;
}
int nCharCountValue = strlen(chReading) - nCharCountName - 1;
chReading[nCharCountName] = 0;
// 复制数据
m_chItems[m_nItemCount] = (char*)malloc(nCharCountName + 1);
strcpy(m_chItems[m_nItemCount], chReading);
m_chItemValues[m_nItemCount] = (char*)malloc(nCharCountValue + 1);
strcpy(m_chItemValues[m_nItemCount], chReading + nCharCountName + 1);
m_nItemCount++;
}
return true;
}
// 读取配置项
char* MFCINi::Read(char *nItem)
{
if (m_nItemCount == 0)
{
return NULL;
}
int i = 0;
while (strcmp(m_chItems[i], nItem) != 0)
{
i++;
if (i == m_nItemCount)
{
return NULL;
}
}
return m_chItemValues[i];
}
void MFCINi::Close()
{
if (m_pf != NULL)
{
fclose(m_pf);
m_pf = NULL;
}
for (int i = 0; i < m_nItemCount; i++)
{
// 释放第i个配置项内存
if (m_chItems[i] != NULL)
{
free(m_chItems[i]);
m_chItems[i] = NULL;
}
// 释放第i个值内存
if (m_chItemValues[i] != NULL)
{
free(m_chItemValues[i]);
m_chItemValues[i] = NULL;
}
}
// 释放配置项内存
if (m_chItems != NULL)
{
free(m_chItems);
m_chItems = NULL;
}
// 释放值内存
if (m_chItemValues != NULL)
{
free(m_chItemValues);
m_chItemValues = NULL;
}
m_nItemCount = 0;
}
2:存储配置文件信息的结构体ConfigInfo:
struct ConfigInfo
{
int nLeft; // 左
int nRight; // 右
int nTop; // 上
int nBottom; // 下
int nID; // 控件ID
char* chType; // 控件类型
char* chText; // 控件文本
char* chKey; // 控件主键
};
3:存储创建窗体样式的结构体:
struct CreateWndStruct
{
int nWndType; // 窗体类型
DWORD dwstyle; // 窗体样式
DWORD dwExStyle; // 扩展样式
LPCTSTR lpszClass; // 对应类
LPCTSTR lpszName; // 名称
DWORD style; // 样式
HWND hwndParent;
HMENU hMenu;
HINSTANCE hInstance;
LPVOID lpCreateParams;
};
4:创建公共函数类ToolKit:
声明:
class ToolKit
{
public:
static char* TrimForCharArray(const char* chRes);
static void ShowMessageBox(char* chText);
ToolKit();
virtual ~ToolKit();
};
实现:
#include "stdafx.h"
#include "ToolKit.h"
//////////////////////////////////////////////////////////////////////
// Construction/Destruction
//////////////////////////////////////////////////////////////////////
ToolKit::ToolKit()
{
}
ToolKit::~ToolKit()
{
}
void ToolKit::ShowMessageBox(char *chText)
{
AfxMessageBox(chText);
}
char* ToolKit::TrimForCharArray(const char *chResource)
{
char *chRet = NULL;
char *pchSeparator = NULL;
pchSeparator = strstr(chResource, "");
int nCharCountName = pchSeparator - chResource;
if (nCharCountName < 0)
{
return chRet;
}
int nCharCountValue = strlen(chResource) - nCharCountName - 1;
// 复制数据
chRet = (char*)malloc(nCharCountName + 1);
strcpy(chRet, chResource);
return chRet;
}
5:创建主要的基类CSearchBaseDialog:
声明:
#include "ToolKit.h"
#include "MFCINi.h"
class CSearchBaseDialog
{
private:
public:
CSearchBaseDialog();
virtual ~CSearchBaseDialog();
ConfigInfo GetConfigStruct(char* chValue);
public:
/**-----------------------------------------------------------------------------

virtual void DrawItem(WPARAM wParam,LPARAM lParam);

public:

//HWND CreateControl(char *chKey, char *chValue);
HWND CreateControl(const ConfigInfo &info);

程序代码:
主要思路是：
1：提供一个基类CSearchBaseDialog，在基类中，程序从配置文件中读取界面控件的信息，然后根据配置文件中的信息在界面上创建相应的控件。
配置文件的格式：
IDC_BTN_MAIN_MENU=10;80;10;40;102;button;菜单
解释：
IDC_BTN_MAIN_MENU=left;right;top;bottom;nID;controlType;TEXT
即：
IDC_BTN_MAIN_MENU=x坐标;y坐标;top坐标;bottom坐标;控件句柄数;控件类型;控件文本
