问题 I want to generate Excel report identical that we use before (with old version of Excel). The only problem is that all cells in old style reports were presented as strings with apostrophe character: I created basically the same report with the next code: oleDbConnection = new System.Data.OleDb.OleDbConnection( "provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileFullPath + ";Extended Properties='Excel 12.0 Xml;HDR=YES' "); oleDbConnection.Open(); oleDbCommand.Connection = oleDbConnection;

问题 I have a project in which I have to use Visual Studio 2008, and I'm trying feverishly to add a Page Footer. It adds from the top menu in VS 2008 under "Reports" However, I cannot see it getting displayed. I have a Excel export link that rips through all the code rendering out the RDLC into Excel.

问题 I have created excel workbook using .NET interop. The excel workbook is created successfully through my C# code. When the user makes any changes in the excel, I want to do some stuff.

问题 Apparently Excel is hardcoded to only allow 255 characters in footers (and headers I think). Naturally I wanted to put more than that in the footer hence this post. Header Workaround: I found that putting stuff in the RDLC header and setting PrintsOnFirstPage and PrintsOnLastPage to true, when exported DOESN'T actually put the RDLC header items into the Excel Header it just uses a split region (with an empty Excel header) and you can put in as much as you like. Visually it's OK but obviously

问题 I am using the VBA-code below to open a csv-file in Excel (the code simulates the Data\Text to Columns - command). In the code it's necessary to specify an array for the property TextFileColumnDataTypes , which for every column in the csv-file specifies a data format (2 = text format). However, since I don't know how many columns the csv-file will have, I would like to specify the format 2 (= text format) for ALL columns in the csv-file. The problem right now is that I can only specify the
