RPC_E_SERVERFAULT Error On Opening An Excel File In Asp.net

Apr 13, 2011

I'm trying to open an Excel file to get and set some values. Unfortunately, I have no choice, I must to work with Excel.

Dim xAp As New Microsoft.Office.Interop.Excel.Application
Dim xWkb As Microsoft.Office.Interop.Excel.Workbook

xWkb = xAp.Workbooks.Open("c:uploads este.xls")

Always I have this exception: (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))

Need I Excel installed in server machine to open Excel files? I don't think so, because when I create a new application and workbook throught code, all things go right, but... its a possibility...

Error Opening Excel File From .net 2010?

Aug 26, 2009

Dim excel As New Microsoft.Office.Interop.Excel.Application()
Dim wb As Microsoft.Office.Interop.Excel.Workbook = excel.Workbooks.Open(txtFileLocations.Lines(w))
Dim ws As Microsoft.Office.Interop.Excel.Worksheet = TryCast(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)

when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?

Excel 2007 Macro - Runtime Error 1004 After Saving And Re-opening A File

Oct 25, 2009

I have an Excel file with utilizes macros to allow a user to enter names of people and then double click on cells to enter ratings via radio buttons. When I open a blank file and enable the macros, I can add users, rate their skills using the radio buttons, etc. with no issue. I then SaveAs the file and continue working on it. once I Save and CLOSE the file, then go to re-open it, the trouble begins. Keep in mind, there is no alteration to the macros directly. Just entering data and using the form as intended. Here's what happens.

I reopen the file.I enter in the name of a person on one line. I go to the first box - double click on it.It is supposed to pop up a dialog box which allows me to choose a rating via radio button (as I had been doing before I closed the file). Instead, in that first column of ratings, it instead gives me the following error:

Runtime error '1004'Unable to set the LineStyle property of the Border class

When I hit "debug" this is the code it points to:

If ActiveCell.Column = leftb Then Range(Cells(ActiveCell.Row, leftb), Cells(ActiveCell.Row, rightb + 1)).Borders(xlEdgeTop).LineStyle = xlContinuous I have no idea why this would not work when I re-open the file!

note that when I go to click on the subsequent cells (there are 8 cells in which you provide ratings, moving across the columns with each cell) - the 2nd through 8th cells function fine. The dialog box pops up, the rating can be selected. it's just the FIRST cell that gives the issue What would possibly be the cause of this? We need users of this form to be able to save, close, and re-open it if needed.

VS 2005 : Error In Opening An Excel File : Old Format Or Invalid Type Library

Feb 24, 2012

I am trying to open an Excel file using the following commands:

xlsWB = xlsApp.Workbooks.Open(filename, , True)

where 'filename' is the name of the file.However I am getting the following error message:

Message = "Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))"

I originally developed an application where I used the above code with default language setting of "English" (under regional and language settings). When I am changing the language setting to "French", the above errror comes up. I am changing the language setting to French in order to simulate an error when this application is run in a French version computer.

Office Automation :: Excel Automation Causing: Rpc_e_serverfault

Jun 1, 2010

We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.

This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.

My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.

Opening An Excel File

Apr 22, 2010

My company is currently using a Linux/Powerterm program that exports reports via email on a daily basis. I have a add-in program installed on outlook to automatically save the report to a folder on the server. The file that is exported appears to be an XLS 97-2003 Worksheet, but I confirmed from the original programmer that this file is not a true Excel file, I believe it is a unicode file, but it can be opened by Excel. I want to link these files to an Access database within my form, but Access does not recognize this file format.I attempted to create several programs in Studio to convert the file to an XLSX file, but on each attempt I receive an error the file is an in unrecognizable format which is killing me at the moment. I even made attempts to dump the data to an dgv but it still wont be accepted.

I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).

.net - Excel Worksheet In Windows Form Application Without Opening Excel Application?

Nov 18, 2011

I am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.

I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:

{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
