Open Excel Workbook On Client Machine With Web Application?

Sep 29, 2009

I'm writing a VB.NET WEB application and I'm fairly new at it. What I want to do is open Excel workbooks on the client workstation so the user can "Save As" or print or basically do whatever they want with it past that point. I've done this in a windows application using System.Diagnostics but all the information I've read so far doesn't seem to work. I can open .txt and .xls files using this approach:[code]but it opens in the browser, which is not what I want. Do I need to mix Javascript with the HTML and the VB code?

.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))."}

Open Excel File And Reusing Existing Excel Instance?

Jul 13, 2010

I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.

The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.

I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.

How can I do the same thing without using the fileopendialog?

I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.

I want to open up an existing instance if my program is already running only if its running the same version.I noticed that this question was asked for only if the name exists, but what if the version is older, I just want to notify the user that an older version is still running, "please remove older version before starting this version."The other link is this one:Return to an already open application when a user tries to open a new instance but they don't talk about closing an instance if an older or newer version is detected.

C# - Excel Interop Quitting The Excel Application Instance Makes Tests Fail?

Feb 23, 2011

I want to encapsulate the use of Excel Interop to make it easier to use somehow in a reuseable library.So far, I have written some tests that work good altogether, except that between each test, I force Excel to quite so that it does have handle on the test file no more in order to be able to delete.Once I quit the application instance between after each of my tests, Excel seems to be no longer responding, causing Windows to display "Excel has stopped working and is looking for a solution"

message. This message lasts a few seconds, meanwhile Excel is closing, causing the hang on the file to occur and my tests to throw an exception like "Cannot access file because it is being used by another process..."

Using VB To Open A .csv File With "excel.workbooks.open"

Using VB to open a .csv file with "excel.workbooks.open", editing it, then saving as .csv.

Even though it is saved as .csv, it is still identified as .xls.

Is there an alternate way to open this .csv file so that when it is saved as .csv the excel application actually identifies it as a comma delimited, not a spreadsheet?

Best Or Better Method To Open Excel File

Jun 2, 2011

Im struggling on how to open an excel workbook without one of two problems.

1. After the first workbook is opened and I close the workbook, if another is opened the worksheet area is "transparent", as in, you can see the desktop or any open app behind excel.

2. Closing excel and opening another workbook after X times (4+?) via the vb.net app I use causes the computer to reboot.

I am stuck thinking it is the method used to open excel within the app.The code below has two methods, both produce the same affect. One method is blocked (makes it easy to test either one).[code]I have two buttons that open workbooks, both have identical code less the workbook requirements.Is there a better or best method to use for opening excel workbooks from vb.net?
