如何在WM_DROPFILES() 中返回文件的大小，创建时间等和文件的相关信息？[已解决]
本帖最后由 xwt620 于 2011-11-24 01:07 编辑Func WM_DROPFILES($hWnd, $msgID, $wParam, $lParam)
Local $nSize, $pFileName
Local $nAmt = DllCall("shell32.dll", "int", "DragQueryFile", "hwnd", $wParam, "int", 0xFFFFFFFF, "ptr", 0, "int", 255)
$aDroppedFiles = 0
Dim $aDroppedFiles[$nAmt + 1]
For $i = 0 To $nAmt - 1
$nSize = DllCall("shell32.dll", "int", "DragQueryFile", "hwnd", $wParam, "int", $i, "ptr", 0, "int", 0)
$nSize = $nSize + 1
$pFileName = DllStructCreate("char[" & $nSize & "]")
DllCall("shell32.dll", "int", "DragQueryFile", "hwnd", $wParam, "int", $i, "ptr", _
DllStructGetPtr($pFileName), "int", $nSize)
$aDroppedFiles += 1
$aDroppedFiles[$aDroppedFiles] = DllStructGetData($pFileName, 1)
$pFileName = 0
Next
ReDim $aDroppedFiles[$aDroppedFiles + 1]
EndFunc ;==>WM_DROPFILESRT，这段代码只能返回文件名，我想从这个函数中返回我需要的文件信息，然后用数组返回。
如果有这方面链接也可以。 自己在函数里面加 FileGetTime 不就行了 这个是干什么用的？能解释一下函数的参数和作用吗？ 这个是干什么用的？能解释一下函数的参数和作用吗？

这个还需要解释吗？参见GUIRegisterMsg的帮助说明
如下面的代码，你拖一堆文件到窗口，就明白 了

这个方法我找了好久了 谢谢lz和楼上的 回复 2# afan
回afan大大，我知道用FileGetSize、FileGetTime可以获取文件相关的信息，但是我看到很多源码里用DllStructGetData函数返回信息很方便，其实我也是想学习下DllStructGetData函数，但是苦于找不到好的学习资料。 回复 5# kyniel
