在站內搜尋過了...但還是解決不了問題... 我是用OpenDialog先給出目的地,但是copyfile出了問題.試過用StringReplace(),解決"\\"問題...但是還不行呀!!!  

 
void __fastcall TMainForm::FileNew1Execute(TObject *Sender)
{
   AnsiString sz;
   TReplaceFlags Flags;
   Flags<Title="Give a name";
        if (OpenDialog->Execute()){
                sz=OpenDialog->FileName.c_str();
                ShowMessage(sz);
                //AnsiString sz1=StringReplace(sz, "\\", "\\\\", Flags);
                //ShowMessage(sz1);
           if(CopyFile("_.md_",sz.c_str(),false))
                CreateMDIChild(OpenDialog->FileName);
           else{
                GetLastError();
                ShowMessage("Cannot copy file - errno = "   String(errno));
           }
        }
}

您好:    PO程式碼的方式請參考版規說明,煩請修改謝謝您的配合 >

Ross 您好：    您將 CopyFile() 的參數放反了，改成如下所示即可：    if(CopyFile(sz.c_str(), "_.md_", false))

不會把.... Copies the source file to the destination file. function CopyFileTo(const Source: string; const Destination: string): Boolean; Parameters const Source: string Source file name. const Destination: string Destination file name. Returns Boolean - True if the file is copied, False on error. Description CopyFileTo is a function used to copy the file specified in Source to the file specified in Destination. CopyFileTo will return False if the file in Destination already exists. CopyFileTo encapsulates the platform-specific calls needed to perform the file copy operation. On the Windows platform, this is the Win32 API function CopyFile. On the Linux platform, CopyFileTo uses a TFileStream instance to create the destination file.

Ross 您好：    您在您自己的範例中使用的是 CopyFile() 而不是 CopyFileTo()，CopyTo() 的說明資料如下：

The CopyFile function copies an existing file to a new file.     BOOL CopyFile(
    LPCTSTR lpExistingFileName,        // pointer to name of an existing file 
    LPCTSTR lpNewFileName,        // pointer to filename to copy to 
    BOOL bFailIfExists         // flag for operation if file exists 
);     Parameters    lpExistingFileName
    Points to a null-terminated string that specifies the name of an existing file.     lpNewFileName
    Points to a null-terminated string that specifies the name of the new file.     bFailIfExists
    Specifies how this operation is to proceed if a file of the same name as 
    that specified by lpNewFileName already exists. If this parameter is TRUE 
    and the new file already exists, the function fails. If this parameter 
    is FALSE and the new file already exists, the function overwrites the existing 
    file and succeeds.

我想大大你唔會了...我是想張"_.md_" copy 到 目的地"sz.c_str()"...

Ross 您好：    如果是這樣的話，那麼您最好是將存放 "_.md_" 檔案的路徑一併指定清楚，否則程式會在您指定目標檔案的目錄去讀取 "_.md_" 那個檔案，如果兩個檔案並不是在同一個目錄的話，將會產生錯誤。 如果您的 "_.md_" 檔案與程式放在同一個目錄內，那就改成下列方式試試看：

String tempFile = ExtractFileDir(Application->ExeName) "\\_.md_";
if(CopyFile(tempFile.c_str(),sz.c_str(),false)){
.....
