Reopen A File Immediately After It Closes Via My C# Application

May 18, 2012

I ran out of ideas and couldn't find any reference about it so here I go... I need to keep a secondary application wich is not related to my c# project always running in background. So if this secondary application crashes or someone else close it manually it will automatically re launch again via my c# app.

I have no clue of how to accomplish this one, I mean checking if this application closes by something external to my c# app.

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"?

VB Runtime Error 1004 - Excel File - Save ?

May 27, 2008

Here are some important facts:

This code works (no Error 1004 on numerous laptops and desktops) A couple of months ago it began to fail (Error 1004 reared it's ugly head) on a couple of machines. The users claim that nothing changed - I can neither confirm nor deny accuracy of these claims. All users, except one, are running Windows XP and Office 2003. The problem also surfaced on a new machine running Windows XP and Office 2007. I could not force the error on my development/test machine - Windows XP with Offic 2003. It fails every time on another machine I have running Vista with Office 2007

The following is the code that causes me the problem. I know the error is raised on the WB.Save statement. I added the error trap to eliminate the problem of the Excel file being unaccessable without a reboot, due to the fact that Windows thought Excel still had it open.

Cannot Open Excel File - Error 0x800AC472 - User Permission

Apr 10, 2012

This is a simple fragment of my code:

[Code]...

The last line throws an exception "Cannot open file" with certain end-user profiles. It works perfectly fine when executing from an Admin account. I just cannot figure out what user privileges and access settings may cause the error. Note that it also works with some end-user accounts (not admins). What missing user rights can cause this?

Write & Close & Reopen & Read Files

This question only applies to files of line-terminated/text strings.[code]I suspect that ultimately, I will generate the myfiles version of the HD file as I write it to disk,but at this point in my VB.net 'skills', until I can prove what I've written by reading it back and having control of it in my program, I can't assume anything about the data/format/file that I have written.

Forms :: Close And Reopen Child Form Within Parent?

Dec 22, 2010

When my application first loads the parent opens and I select my child form from toolstrip:

'In parent open the form when option is clicked
Public Sub Showfrmitemreview(ByVal sender As Object, ByVal e As EventArgs) Handles itemreivewStripMenuItemA.Click, itemreviewStripMenuItemB.Click

Nothing happens I don't even get an error message. I've played around with the code numerous times and the only thing that worked was to have it open outside of the parent which I do not want to happen.

Error - Microsoft Office Excel Cannot Access The File 'D:OfficeStationaryV0.2ReportTMPReportItem.xlsx'

May 19, 2011

I used Visual Studio 2005. It works well when testing, but when I publish it got error: Microsoft Office Excel cannot access the file 'D:OfficeStationaryV0.2ReportTMPReportItem.xlsx'. There are several possible reasons: - The file name or path does not exist. - The file is being used by another program. - The workbook you are trying to save has the same name as a currently open workbook.

my following code is:

Dim ExcelApp

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.

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

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.

Asp.net Using Oledb To Export Excel File Returns Empty Excel File

Feb 24, 2010

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

Office Automation :: Error With Excel Dll On Server Without Excel?

Jun 15, 2011

We have a VB 2005 program that reads data from a database and builds an Excel output file to be emailed. This works fine from my computer but when we put it on the server it fails on the Excel functionality.

The error is: Unhandled Exception: System.Runtim.InteropServices.COMException

Although Excel is not installed on the server we did also build a Setup program to install our program. It copies the Microsoft.Office.Interop.Excell.dll to the server folder with the exe.I thought the setup program should register the Excel DLL and the program should work even if the server does not have Office or Excel installed.

Excel Spreadsheet Opens With The Error "this File Is Not In Recognizable Format"?

Apr 9, 2009

[Background]:I created a Winforms App that reads data and spits it out into an Excel Spreadsheet. On my computer, I have Microsoft Office 2003 and inside of the Visual Studio Project, I referenced COM Object "Microsoft Excel 11.0 Object Library". The Executable is on a shared directory and end users can run the application and generate the reports themselves.

[Problem]:Problems arise when an end user with Microsoft Office 2007 runs the application, generates the Excel Spreadsheet and sends it to someone with Microsoft Office 2003, the Excel Spreadsheet opens with the standard "this file is not in recognizable format" error and when you push "ok", the data shows up as symbols (garbled text).

[Question]When I reference "Microsoft Excel 11.0 Object Library" in my project, how does the .Net Framework (or my Application) find this COM Object object when it is ran from another CPU?I guess, I would like to know how references work. When you reference DLLs in a VS.Net project, compile the program and then put the execuable on another PC, how does VB.Net go about finding those DLLs you referenced or is it part of the compiled program?

I suspect when a user running MS Office 2007 runs my app, it is running a 2007 dll instead of a 2003 dll.However, I would think an error would be thrown if this was the case.

Open/ Modify Excel Through ADO.net - Error: System.Data.Odbc.OdbcException: ERROR [42000]

Jun 22, 2010

I'm writing an application that imports and tidy up address data into a cleaned, deduped excel workbook ordered in rows with each column as an address field. One of the issues I've ran into is that we sometimes get a workbook where the multiple address fields are held in a single cell with line breaks. I've written code to extract all of this data out of the excel sheet in to a dataset with each sheet as a table and the address fields contained within. I now want to create a new Excel workbook from this data with the address fields in Row and columns the problem I have is I can Open/create the Workbook but when I try to insert a new Sheet (Table) I get an error saying the Workbook is read only....
