HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\*\MRUList
這里的值記錄的是檔案歷史打開保存記錄
在xp系統下，資料型別是reg_sz, 通過RegistryGet函式可以直接取出來用。
代碼示例如下：
string ls_express, ls_dir
long ll_rtn
blob lbl_temp
ls_express = 'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\*'
ll_rtn = RegistryGet(ls_express, "MRUList", Regstring! , ls_dir)
但在vista/win7里。 注冊表位置和資料型別都變了
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePidlMRU\*\MRUListEx
資料型別是reg_binary, 通過RegistryGet函式取出來后，應該做一個轉換才能使用。
我的做法是:
string ls_express
long ll_rtn
blob lbl_temp
ls_express = 'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePidlMRU\*'
ll_rtn = RegistryGet(ls_express, "MRUListEx", RegBinary! , lbl_temp)
現在我就卡在這里了。lbl_temp無法正確轉為string。
特在此請教各位前輩。。

你自己測驗一下，自己寫的regbinary!，能否正常取出并轉換blob lb
registrySet( "HKEY_LOCAL_MACHINE\SOFTWARE\aa", "aa",RegBinary!,blob('測驗一下'))
registryGet( "HKEY_LOCAL_MACHINE\SOFTWARE\aa", "aa",RegBinary!,lb)
messagebox('',string(lb))

string ls_expresslong ll_rtn
blob lbl_temp
ls_express = 'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSavePidlMRU\*'
ll_rtn = RegistryGet(ls_express, "MRUListEx", RegBinary! , lbl_temp)
messagebox('', string(lbl_temp, EncodingANSI!))
messagebox('', string(lbl_temp, EncodingUTF8!))
以下是pb中string的幫助說明，請參考
