备注：
编程环境VC6.0
第一个问题：,经过调试发现：
pHdr->apRes[0]->cx=68
pHdr->apRes[1]->cx=68
pHdr->apRes[2]->cx=68
pHdr->apRes[0]->cy=105
pHdr->apRes[1]->cy=105
pHdr->apRes[2]->cy=105
为什么，我的rc文件中的三个对话框的描述都不是这个宽度和高度？？？？
第二个问题：
// Map the rectangle from dialog box units to pixels.
MapDialogRect(hwndDlg, &rcTab);
这个函数到底是干嘛的？经过这个函数调用以后，68变成了136，105变成了210，都变成原先的二倍，不理解。
第三个问题：
TabCtrl_AdjustRect(pHdr->hwndTab, TRUE, &rcTab);
这个函数到底是干嘛的？弄的头大。

它做了很多包装，代码量很少，而且界面可以用鼠标拖拉控件来设计，不写一行代码。

c+ +builder不也是调用windows–api吗？他怎么会简单！

解释不对，我的三个对话框宽度和高度各不一样，请看rc文件，获取的结果却是一样的！！！

1、用的单位是不同的，运行时获取的默认是像素
2、https://msdn.microsoft.com/en-us/library/ms645502(v=vs.85).aspx
Converts the specified dialog box units to screen units (pixels). The function replaces the coordinates in the specified RECT structure with the converted coordinates, which allows the structure to be used to create a dialog box or position a control within a dialog box.
3、TabCtrl_AdjustRect是个宏，相当于发送TCM_ADJUSTRECT消息，调整控件大小

SDK编程挺繁琐的，不知道楼主对C++ Builder有没有兴趣呢？可以了解一下。

赵老师，第二个问题和第三个问题似乎明白了，第一个问题呢？怎么解释呢？

MapDialogRect
The MapDialogRect function converts (maps) the specified dialog box units to screen units (pixels). The function replaces the coordinates in the specifiedRECT structure with the converted coordinates, which allows the structure to be used to create a dialog box or position a control within a dialog box.
BOOL MapDialogRect(
HWND hDlg, // handle of dialog box
LPRECT lpRect // address of structure with rectangle
);
Parameters
hDlg
Identifies a dialog box. This function accepts only handles for dialog boxes created by one of the dialog box creation functions; handles for other windows are not valid.
lpRect
Pointer to a RECT structure that contains the dialog box coordinates to be converted.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, callGetLastError.
Remarks
The MapDialogRect function assumes that the initial coordinates in theRECT structure represent dialog box units. To convert these coordinates from dialog box units to pixels, the function retrieves the current horizontal and vertical base units for the dialog box, then applies the following formulas:
left = (left * baseunitX) / 4
right = (right * baseunitX) / 4
top = (top * baseunitY) / 8
bottom = (bottom * baseunitY) / 8
In most cases, the base units for the dialog box are the same as those retrieved by using the GetDialogBaseUnits function. If the dialog box template has the DS_SETFONT style, however, the base units are the average width and height, in pixels, of the characters in the font given by the template.
QuickInfo
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Requires version 1.0 or later.
Header: Declared in winuser.h.
Import Library: Use user32.lib.

TabCtrl_AdjustRect
VOID TabCtrl_AdjustRect(
HWND hwnd,
BOOL fLarger,
RECT FAR *prc
);
Calculates a tab control's display area given a window rectangle, or calculates the window rectangle that would correspond to a specified display area. You can use this macro or send the TCM_ADJUSTRECT message explicitly.
No return value.
hwnd
Handle to the tab control.
fLarger
Operation to perform. If this parameter is TRUE, prc specifies a display rectangle and receives the corresponding window rectangle. If this parameter is FALSE, prc specifies a window rectangle and receives the corresponding display area.
prc
Address of aRECT structure that specifies the given rectangle and receives the calculated rectangle.
