MFC保存照片到指定的文件中

[W大鹏]

我在代码项目中文件根目录下新建了一个Pic文件夹，Pic文件夹中要跟随我抓拍保存的照片信息生成对应的 年 月 日 这样格式的文件夹。我该怎么写代码。

void CCapturePictureDlg::OnOnePicture(LONG ILoginID, BYTE *pBuf, UINT RevLen, UINT EncodeType, UINT CmdSerial)
{
	//Get file path
	char path[1000];
	int filelen = GetModuleFileName(NULL,path,1000);
	int i = filelen;
	while(path[i]!='\\')
	{
        i--;
	}
	path[i + 1] = '\0';
 
    CString filepath(path);
	CString filename = "mpeg4.JPG";
	CString strfile = filepath + filename;
	char *pFileName = strfile.GetBuffer(200);

现在的路径是这样的

每次都调用CreateDirectory函数创建“年月日”目录，CreateDirectory第一个参数为 Pic目录 + 年月日字符串，格式化一下即可。
