獲得某子控制元件或子表單句柄，怎么利用SendMessage函式去實作通過句柄 點擊這個表單的內部坐標

我用gdi取得了DPI的解析度和像素，想計算圖片的列印尺寸（厘米），可是要取影像解析度（PPI）,我看EXIF中有這個資訊，不知道怎么取，請教各位大大

推薦使用clswindow，參考：http://blog.csdn.net/sysdzw/article/details/9083313
http://download.csdn.net/detail/sysdzw/9295969
以下是簡單的一個演示例子，獲得當前記事本的句柄并設定為活動視窗，然后點擊此視窗內40,40的坐標，也就是檔案選單
Dim w As New clsWindow
w.GetWindowByClassNameEx("Notepad").Focus
w.ClickPoint w.Left + 40, w.Top + 40

/* CaptureScreen(aRect, bCursor, sFileTo, nQuality)
1) If the optional parameter bCursor is True, captures the cursor too.
2) If the optional parameter sFileTo is 0, set the image to Clipboard.
If it is omitted or "", saves to screen.bmp in the script folder,
otherwise to sFileTo which can be BMP/JPG/PNG/GIF/TIF.
3) The optional parameter nQuality is applicable only when sFileTo is JPG. Set it to the desired quality level of the resulting JPG, an integer between 0 - 100.
4) If aRect is 0/1/2/3, captures the entire desktop/active window/active client area/active monitor.
5) aRect can be comma delimited sequence of coordinates, e.g., "Left, Top, Right, Bottom" or "Left, Top, Right, Bottom, Width_Zoomed, Height_Zoomed".
In this case, only that portion of the rectangle will be captured. Additionally, in the latter case, zoomed to the new width/height, Width_Zoomed/Height_Zoomed.
Example:
CaptureScreen(0)
CaptureScreen(1)
CaptureScreen(2)
CaptureScreen(3)
CaptureScreen("100, 100, 200, 200")
CaptureScreen("100, 100, 200, 200, 400, 400") ; Zoomed

樓上，針對樓主的問題發代碼，別亂復制。 正好也能學習學習。uj5u.com熱心網友回復：
你這樣說，豈不是有意刁難它？
uj5u.com熱心網友回復：
我覺得他應該真會，針對性的撰寫代碼分享下，大家也可以學習學習。說實話近十年了，看到ahk的回帖我就想刪，但是不能隨便刪。
趙四哥們，你把你回復過的所有ahk的帖子翻出來，看看有多少人關注或者樓主采用的。光發一個鏈接就是垃圾回復，對樓主來說毫無價值。你要是覺得是個非常好的東西忍不住要分享的話請務必帶對應代碼，否則就是個隱形帖，大家都無視了。
