关于VC中得到窗体标题

怎样得到另一个窗体的标题文本
用GetDlgItemText函数具体怎样实现？谢谢！
谢谢2位 请问具体怎么实现 比如获得一个VB窗体的标题 并保留到str中

Answer 1

CWnd::GetDlgItemText
Call this member function to retrieve the title or text associated with a control in a dialog box.
//用这个函数重新得到对话框的标题

int GetDlgItemText(
int nID,
LPTSTR lpStr,
int nMaxCount
) const;
int GetDlgItemText(
int nID,
CString& rString
) const;

Parameters//参数
nID
Specifies the integer identifier of the control whose title is to be retrieved.
//对话框的ID号
lpStr
Points to the buffer to receive the control's title or text.
//读取后存放标题的指针型变量
nMaxCount
Specifies the maximum length (in characters) of the string to be copied to lpStr. If the string is longer than nMaxCount, it is truncated.
//定义字符串的最大尺寸,如果超过这个尺寸,将被切除掉.这个尺寸是上一参数lpStr的尺寸
rString
A reference to a CString.
//一个访问的字符串?
Return Value//反回值
Specifies the actual number of characters copied to the buffer, not including the terminating null character. The value is 0 if no text is copied.
//指定一个给定尺寸的字符串型的缓存,这个字符串的结尾不是NULL(\0)
如果,没有读到标题,返回值为0
Remarks
The GetDlgItemText member function copies the text to the location pointed to by lpStr and returns a count of the number of bytes it copies.
//这个函数,通过参数lpStr来传递标题,并返回标题的字节数.

Answer 2

HWND FindWindow( LPCTSTR lpClassName,
LPCTSTR lpWindowName
);
Parameters

lpClassName
[in] Pointer to a null-terminated string that specifies the class name or a class atom created by a previous call to the RegisterClass or RegisterClassEx function. The atom must be in the low-order word of lpClassName; the high-order word must be zero.
If lpClassName points to a string, it specifies the window class name. The class name can be any name registered with RegisterClass or RegisterClassEx, or any of the predefined control-class names.

If lpClassName is NULL, it finds any window whose title matches the lpWindowName parameter.

lpWindowName
[in] Pointer to a null-terminated string that specifies the window name (the window's title). If this parameter is NULL, all window names match.
