FindResource找不到資源雖然他們存在

Question

我的fingers are hurtin'。我試圖從我的exe使用WinApi（FindResource）加載資源。我已經使用WinApi成功創建了一個字符串資源，並驗證了它們與PE Explorer，Resource Hacker和Hex Editor存在。

我不能做的是通過FindResource找到它們。該函數完成後，返回一些指針並將LastError設置爲0.但指針b指向無效內存。我嘗試以4種不同的方式導入FindResource，並且都有相同的結果（b1，b2，b3，b4表示每個聲明的b）。我發現我需要調用LoadLibrary率先做出FindResource找到「東西」（A1 = A2 2個相同的模塊處理該點正是 exe文件的開頭在內存中加載後，就具有不同的功能獲得） 。

我以爲 a（a = a1 = a2）和 b必須位於相同的存儲空間（偏移到模塊開始？）。但b與a的差別始終是相同的16568.在十六進制編輯器中，我發現我的字符串在8000左右的某個位置，並且在創建每個資源之後會有所不同。我有想法可能是錯誤的，但我不知道：

• MAKELANGID(0, 0)〜我的理解是0和0立場中立的，我讀的地方，有可能是一些關於*.mui文件？
• 創建資源破碎資源？其實這兩個資源編輯器都沒有問題顯示我的資源
• 進口聲明可能是錯誤的，但我已經嘗試了這麼多的可能性，那些是最好的
• 資源需要打開/鎖定/不管？

如何成功找到資源？我的代碼中是否有錯誤？

我知道有很多很多，大約FindResource很多帖子在互聯網上，我讀了很多人，但什麼都沒有這個問題解決。

Answer 1

FindResource()返回句柄，而不是指向資源的指針;它需要更多的步驟來獲取數據。您需要LoadResource()然後LockResource()以獲取指向實際資源字節的指針。

據我可以告訴這是從16位的舊天保留。
