我必須創建一個軟件，它將掃描多個目錄並提取有關找到的可執行文件的信息。如何使用C++獲取有關Windows可執行文件（.exe）的信息
我需要做兩件事情：
.exe，.dll，等等） - 檢查擴展可能不夠好。我從來沒有這樣做過，因此我不知道是否有Windows API（或輕量級C/C++庫）來做到這一點，或者甚至可能。我想是的，因爲explorer.exe這樣做。
你們知道什麼可以指引我朝着正確的方向嗎？
非常感謝您的幫助。
您可以根據需要驗證儘可能多的PE File Format。如果你願意，你也可以檢查PE file signature。然後，您可以使用File Version API來檢索公司名稱，產品名稱，版本號等。
您可能會發現this CodeProject article which wraps the file version API對第二項任務有幫助。要檢查文件是否可執行，您可能需要解析PE headers。
謝謝！我一定會看看;） – ereOn 2010-05-07 13:59:14
檢查這個代碼，並根據需要烏爾修改....

Program to dump the PE,DOS headers and Hex Dump of particular section

BRIEF VIEW OF PE FILE
.----------------------.
| |
| Other stuff not |
| touched in this |
| program |
| |
|----------------------|
| |
| Various Section like |
| ..... |
| ..... |
.------>| .reloc |
| .---->| .idata |
| | .-->| .data |
| | | .>| .text |
| | | | |----------------------|
'-|-|-|-| | <--- Each entry in section table have pointer
'-|-|-| Section | offsets to actual sections
'-|-| Header or Table |
'-| | ---.----------------.
|----------------------|-----/ | PE Optional | 1) ImageBase
| | | Header |
| | | |
| NT Headers | |----------------|
| | | COFF/PE | 1) NumberOfSections
| | | Header Info | 2) SizeOfOptionalHeader
|----------------------|----- |----------------|
| UNUSED | \ | PE Signature |
|----------------------| ---'----------------'
| MS-DOS stub |
|----------------------|
| UNUSED |
|----------------------|
| MS-DOS Header | <-- Here at 0x3c location we have the offset of NT Header
'----------------------'
Structres related to these exe headers
--------------------------------------
1) MS-DOS Header ---> IMAGE_DOS_HEADER
2) NT Header ---> IMAGE_NT_HEADERS --->contain
--->IMAGE_FILE_HEADER dealing with COFF/PE Header
--->IMAGE_OPTIONAL_HEADER dealing with Optional PE Header
3) Section Table ---> IMAGE_SECTION_HEADER
Key Points
----------
dosHeader = Memory mapped base address
ntHeader = (IMAGE_NT_HEADER)((DWORD)dosHeader + dosHeader->e_lfanew)
sectionHeader = (IMAGE_SECTION_HEADER)((DWORD)ntHeader + OFFSET(OptionalHeader) + sizeof(OptionalHeader))
each section = (char *)((DWORD)dosHeader + sectionHeader.PointerToRawData)
