如何检查某个文件是否已在某些 Excel 实例中打开？

我使用 DXL (DOORS) 语言，但它应该独立于这种语言。

我可以调用任何 OLE 方法来检查打开了哪个文件并将其与路径/文件名进行比较？

如果可能的话，我可以只关闭那个 Excel 应用程序中的那个工作表/文件吗？

编辑：这是我到目前为止得到的，这有效但只有一次。DXL 使 Excel.exe 进程保持打开状态，并在接下来的检查中使用没有打开的工作簿甚至根本没有窗口的实例。

        if (confirm "File \"" fPath "\" already exists. Do you want to overwrite it?") {

        // check if file is opened in any Excel instance
        OleAutoObj oleWorkbooks     = null;
        OleAutoObj oleExcel         = null;
        OleAutoObj oleWorkbook      = null;
        OleAutoArgs autoArgs = create;

        oleExcel = oleGetAutoObject("Excel.Application");
        bool opened = false;
        // if excel is opened
        if(oleExcel != null){
            d("Excel is opened");
            // Get workbooks and open file
            oleGet(oleExcel,"Workbooks", oleWorkbooks);

            // compare each open workbook
            int count = 0;
            oleGet(oleWorkbooks,"Count", count);
            string workbookname = "";
            string sPath = replace(fPath, "\\", "/");
            sPath = stripPath(sPath, true);

            while (count > 0) {
                d("checking opened document");
                clear(autoArgs);
                put(autoArgs, count);
                oleGet(oleWorkbooks,"Item", autoArgs, oleWorkbook);
                oleGet(oleWorkbook, "Name", workbookname);
                opened = sPath == workbookname;
                if(opened) {
                    if(confirm "The file is currently opened in Excel. It must be closed. Do you want to close the document?") {
                        clear(autoArgs);
                        oleMethod(oleWorkbook,"Close",autoArgs);
                    }
                    break;  
                }
                count--;
            }
        }
        oleCloseAutoObject(oleExcel);
        oleCloseAutoObject(oleWorkbooks);
        oleCloseAutoObject(oleWorkbook);
        // todo leaves excel process open

        if(!opened) {
            streamOutputData = write fPath;
            streamOutputData << sOutput;
            close streamOutputData;
            return true;    
        }
    }

使用现有的 DXL 方法 canOpenFile(string path, bool write) 解决了它：

if (confirm "File \"" fPath "\" already exists. Do you want to overwrite it?") {
        if(canOpenFile(fPath, true)) {
            streamOutputData = write fPath;
            streamOutputData << sOutput;
            close streamOutputData;
            return true;    
        }
        else {
            e("File \"" fPath "\" is opened in another program. Close it! (It's probably Excel ;) )");
        }
    }

我不知道 DXL，但这是你可以在 VBA 中做的，我让你适应 DXL：

Sub IsXLBookOpen(strName As String) 

     'Procedure designed to test if a specific Excel
     'workbook is open or not.

    Dim i As Long, XLAppFx As Excel.Application 

     'Find/create an Excel instance
    On Error Resume Next 
    Set XLAppFx = GetObject(, "Excel.Application") 
    If Err.Number = 429 Then 
        Set XLAppFx = CreateObject("Excel.Application") 
        Err.Clear 
    End If 
    On Error GoTo 0

     'Loop through all open workbooks in such instance
    For i = 1 To XLAppFx.Workbooks.Count
        If XLAppFx.Workbooks(i).Name = strName Then
           MsgBox("The workbook is open")
           'Close the workbook and ask if user wants to save
           XLAppFx.Workbooks(i).Close
           'Force close and save changes
           XLAppFx.Workbooks(i).Close True
    Next i 
End Sub
