问题 I'm using the Microsoft.Office.Interop.Excel to open an password protected Excel file from my C++/CLI program. I supply a password as the 5th argument. When I run my program, Excel starts and opens my file but it prompts for password. Note that the file is password protected, not the worksheets. According to the documentation the password should be of type object but supplying it as a literal should also work? using namespace System; using namespace Microsoft::Office::Interop::Excel;

问题 I'm reverse-engineering a manually created spreadsheet for dynamic creation. Most of the cells are populated with simple data, but there are a couple that are "sort/Filter" dropdowns like so: How can I dynamically create such a control? Is there a way to "view source" in the Excel spreadsheet to see what sort of code might be required to produce these controls? UPDATE Adapting MacroMark's code, this compiles: var rangeMonthYears = _xlSheet.Range[_xlSheet.Cells[7, 3], _xlSheet.Cells[7, 15]];

问题 I am using Excel interop to create excel workbooks from my query results. When there are thousands of records it takes a long time for the workbook to be generated. The below code is a sample of how I am populating the cells. RowNo = 1 For i = 1 To 4000 ColNo = 1 For j = 1 To 5 Dim cell As excel.Range = ws.Cells(RowNo, ColNo) Dim value = j cell.Value = value ColNo = ColNo + 1 Next RowNo = RowNo + 1 Next For the above code to run it takes more than a minute. How can I optimize it? 回答1: Found

问题 I have an Excel 2007 add-in with a ribbon. One of the buttons in the ribbon triggers heavy manipulations of the current worksheet and I set various Excel.Application properties like Interactive and EnableEvents to false during the manipulations for speed and UX reasons. My problem is that the ribbon doesn't steal focus so if the user was editing a cell when he clicks my ribbon button, an exception is thrown when setting Application.Interactive = false because Excel considers the user is still

问题 Everytime I run this code, the object won't close. I still have an excel.exe running in the task manager. Even if I set the objects = null, still nothing. I've even tried using the objects .Quit() method. What am I doing wrong here? private bool ValidateQM() { //setup the objects Excel.Application oXL = null; Excel.Workbook oWB = null; Excel.Worksheet oSheet = null; int hWnd = 0; try { //Start Excel and get Application object. oXL = new Excel.Application(); hWnd = oXL.Application.Hwnd; oXL

问题 I've got a Class report witch includes a method RunExcelReporting . It knows what workbook to open and what routines to run via a control table. As a test I've just spelled one of the macros incorrectly in the control table. The console application creates an instance of report and runs the RunExcelReporting method but then stops at a point where Excel is diplaying the message box which asks if the user would like to save the workbook. This is a bad halfway house point for me - I'd rather

问题 Problem Overview: I am automating the report generation (excel) for a customer using C# with "native" excel support (microsoft.office.interop.excel) and the EPPlus library.
