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.

Copy UserForm To Email, File Or Word

Feb 3, 2010

I have a Macro that prints Sales Vouchers, is it possible to attach the userform to an Email or write it to a file for later attaching to an email or even send the UserForm to Word again the aim is to transmit the voucher electronically rather than paper. My code at the moment is very simple: UserForm2.PrintForm which prints the form. I tried printing to a file but couldn't get it to work. I am guessing that printing to a file is for Text only and not bit by bit.

I need to open an excel file from and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created.

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 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

Excel - Open A File In An Active Workbook?

Aug 19, 2010

I have a program that filters data and then outputs it to a tabg delimited file. I then use Excel Interop to open this file in Excel because directly outputting to a worksheet takes too long. So currently I am using this code:

Dim WB As Workbook = ExcelApp.Workbooks.Open(AD.DF.DatafileInfo.WriteToFileLocation)
ExcelApp.Visible = True

The first line takes the filtered data and outputs to a tab delimited file. The second opens that same file in a new workbook in Excel. And obviously the third makes Excel visible. Here is my problem though: right now when this code is run there are two open workbooks. I already have an active workbook and I would just like to open this file to that workbook.
