We have created a dll to convert an excel spreadsheet to a csv file. At the moment we open the xls file, an eror occured (file doesn't exist / is used by an other user)
Used
Dim excel As New Microsoft.Office.Interop.Excel.Application
Dim wb = excel.Workbooks.Open("d:my.xls") '<<<<<<<<<<< not possible to open
wb.SaveAs("d:my.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlTextMSDOS)
wb.Close(SaveChanges:=False)
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"?

I cannot find any up-to-date information on the internet on how to successfully open an excel document from a VS 2010 application.
What imports/declares are needed to open, save, close and (if you know) how to enter current values of variables into certain cells in the Excel document from a Visual Studio 2010 application?
I would like to be able to have my users open an Excel file and include their add-ins they have installed and usually show up when Excel normally starts. Using this code, Excel opens with no add-ins visible:
vb.net Dim excel As Microsoft.Office.Interop.Excel.Application
Dim wb As Microsoft.Office.Interop.Excel.Workbook
Try excel = New Microsoft.Office.Interop.Excel.Application
wb = excel.Workbooks.Open(filelocation & "checks.xls")
excel.Visible = True
[Code]...
Is there a property to allow add-ins when opening an Excel file?
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.
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:

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.
I have created a picturebox in a form that I want to click on and then it would send me to a excel file that I already have created. I don't know if it is even possible. Do I need to use a button instead?, or am I just way off all together.

When saving as an xls it works fine but when saving as a htm its a disaster Just a bunch or symbols and stuff. BUT if I go into my xls document and Save As webpage from there, it works fine!
I dont get this. I use code from one project that works and paste into anther and now its full of errors.
I have no clue how to solve this (See attached image).All of the errors have to do with Excel and Outlook applications.The info for "Imports" section is the same as my other project and all the "Dims" are the same as well. (These are two separate projects).Basically, I copied a form from one app and made a stand alone app for that form.
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))."}

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.
