Trying to get names of all visible open excel workbooks. I found code online, that is below.I suspect the code is not working for me because either: I didn't include a reference (in addition to the MS Excel 12.0 Object reference and in addition to the Microsoft Office Interop reference, both were made) or something else basic being missed. i have been using the "early-bound" code below that is recognizing oExcelApp as visible...however, the open excel workbooks that I have open, are not being recognized.
I am using Windows XP and VB in Visual Studio 2010.Here is what I found online; disregard the late-bound if doesn't apply:
I am working with a folder of xls files that are all in identical format (automatically generated by entering numbers into a pricing app). I need to pull the data that is in cell D54 on the worksheet of the same name in every file. Can't seem to get anything to work to make it loop.
I have a bunch of Excel workbooks that contain multiple worksheets. I want to loop through each workbook and export each worksheet into it's own new workbook. I want one worksheet in each new workbook.
Here's what I've got so far: Sub ExportWorksheet(ByVal worksheet As Excel.Worksheet, ByVal filePath As String) Dim xlApp As Excel.Application = New Excel.ApplicationClass Dim xlWorkBook As Excel.Workbook = xlApp.Workbooks.Add worksheet.Select() worksheet.Copy() [Code] .....
When working with Excel in this context, is there a way to get the Excel Application/Workbooks/Sheets events?
Imports System.Runtime.InteropServices Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Process.GetProcessesByName("Excel").Count <> 0 Then
Our small business uses a VB project to 'process' information in excel workbooks. The project works on all machines except one (a new one) which generates a "Runtime Error 9". All machines are using Office 2003. When I try to debug it takes me to the following code, Workbooks(Tempname).Close SaveChanges:=False

I'm trying to upgrade an Excel VBA workbook to a VSTO Excel Add-in in VB.NET using VS 2010. In the original (i.e.- VBA) version I have a modeless UserForm (called frmMain) that floats on top and is visible at all times while the user is still within the Excel application, but is not visible if the user moves to another window outside of Excel.
For example, within Excel the user can click on any worksheet tab, select any cell, etc. and the UserForm is still visible. This is exactly how I'd like it. The problem is, that in the new VSTO add-in, I can not get the Windows form to mimic this same behavior. I use frmMain.Show() to show the form as a modeless form, but the moment the user clicks an Excel worksheet (i.e.- activates a worksheet) the form becomes hidden behind the worksheet.
I would like to open the excel file after create the excel file. The creating file function is done, but the system unable to open the excel file. My coding as below:

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?
i have 4 different excel files of different names.each excel file has 8 columns and 15 sheets.All excel files has same columns and same number of sheets (same sheet names and column names)i have to merge these 4 files into one.that file must be identical to the individual files.i.e same column names,and same number of sheets.
I am trying to get excel sheet name here is my code but it throws an exception "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"
My application searches for a specific worksheet in an open workbook. The code to find the worksheet is:
If Amendaction = True Then If oBook IsNot Nothing Then
For Each ws As Excel.Worksheet In oBook.Sheets
If ws.Name = SheetToFetch Then SheetFind = ws.Name
[code]....
When I execute the code, depending on the worksheet name, the result found in ws.name has one or more spaces in front of the text. e.g. "Bour001" used in creating the worksheet name becomes " Bour001" when returned by ws.name.
How do I find out the hidden excel sheet name using ADO(OLEDB) in C#? In My Excel workbook there are a lot of sheets. Only one Excel sheet is in hidden mode. I need to find out the names of hidden sheets. My code finds both hidden and visible sheets.This is my code to find excel sheet names for all sheets. Is it possible/can any one tell me how to find out hidden excel sheet names without using Interop services in C#?
I have 2 forms (e.g Form1, Form2) which have multiple labels drawn on them (e.g Form1 has Label2,Label3 and Form2 has Label5,Label8).How can I fetch into an excel (or notepad etc) sheet the total number of labels and their names that I have in my forms?
I need to populate a Combo Box with sheet names in an Excel File. I Have an openfiledialog that i search for the excel file and put the dirPath to a textbox, now i need to populate the ComboBox with the sheets in that file, the idea is so when i select sheet3 in the ComboBox, i can pass that sheet name to the string for processing.
I have an excel sheet with image names in column A. I have a directory (with subfolders) on my network with all the images in there plus some.I need to copy only specific files from one location to another.
I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!
I have five menu items that i have created as a user control and placed on the master page. Now i want one of the menu items to be visible only for particular user role and not visible for others. Here is what I did. Its not working though.
I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

what I want to do is have a column name in the excel worksheet which is not included in the code..i'm getting the data from a datagridview but it only shows the data in the excel.. i also want the field name of these data to be shown..another, as you can see in the code given, the directory is fixed.. what do i have to do to choose a directory to save my work? and also, i have many gridviews and whenever i'm exporting my work to the excel worksheet, it always overwrites my work.. i want to choose the directory to save, also show the field names, and make a separate worksheet for every gridview..
I'm using Microsoft Visual Basic 2008 Express and had developed an application to perform Excel.Workbooks.OpenText. I had tried the application on my PC (running Office 2000) and my friend's PC (running office 2007); the software running fine on both PC. But I had experienced error using to application on Office 2000. It's giving me error which read as:
"System.AccessViolationException:Attempted to read or write protected memory. ... at Excel.Workbooks.OpenText"
Does the error relate to Office version i'm using? Or it's PC hardware dependant (like lack of RAM).
