Programmatically Check To See If A Sheet Exists In Excel?
Nov 4, 2010
I was wondering if there is a way to programatically check and see if a sheet exsists in an excel workbook?
Basically what I am doing is checking if an excel document exists, opening it up and checking if the specified sheet exists. I am currently unaware as to how to check and see if the sheet exists.
UPDATE
I have been given some good code to make this work. All i am missing now is the correct imports.
I have searched and found this import :
Imports Tools = Microsoft.Office.Tools.Excel
But for some reason that is not recognized. Do I have to configure VS somehow to make it work? Or am I just using the wrong import?

Whats the easiest way to change a sheet name of a newly create .xls file using VB.net.
The .xls is created as follows in a directory location:
filename = strDirectoryName & "1-TestFeedFile-" & strToday & "-" & iFile.ToString() & "of" & totalFile.ToString() & ".xls"
outputWriter = File.CreateText(filename)
The header of the xls file is created as follows:
line = "Blah1" & Chr(9) & "Blah2" & Chr(9) & "Blah3" & Chr(9)
outputWriter.WriteLine(line)
This code was orginally written to create a .txt file but was changed to a create a .xls, in that case I'm wondering if i'll have to change the code to create an new excel object which then can be used and access its sheet property?I don't mind if the solution is in VB.net or C#

[code] objExcelAppDataSheet is the excel application's object and strTemplatePath is the path of the excel file.This excel file is like a template that i am using in my application. In this file some cells are merged. After copying to the new sheet the formatting of the sheet does not remain same. Columns sizes are changing. Why this problems occurs? Is this MS office versions issue??

I have to provide an Excel file as an output. I have to color some of lines and make them bold.The input is based on a dynamic list (in memory) and it also could be based on CSV file that I'm already provide today (based on the same dynamic list).I'm wondering what would be the most efficient way (in terms of performance) in order to provide the colored Excel output?Should I export directly from dynamic list into Excel - or - Should I export from CSV into Excel ?

So I've got this Excel sheet of employees which have all the information about them. I'm trying to import this info into AD, but in order to do that I need to get the username for these users as well. And I would like vba code or vb.net code that basically takes the value of every row in column D and looks for it in AD and returns the username and adds it to column A. Would something like this be possible?

I have created a connection to an excel file. This is the code i created to select the data in the excel. But i want to make the [sheet1$] to be dynamic, which means it will get the sheet name depending on what is in the excel workbook. This workbook has only one sheet. This is to make sure that there will be no error when the sheet names are different. [code]

I post a question similar to this a few days ago, but nobody answer. Now I modify my request a little bit, I want to read an excel file using VB.NET program. I know the logic below can do this. The logic is shown below.
But I have a question. This logic needs the worksheet name, but usually my application doesn't have this information, the worksheet name cannot be hardcoding. I have 2 request:Can I always upload the first sheet from the selected excel file. (ACCESS can do this without knowing the worksheet name).

I'm able to add a new sheet to an excel ss and name it. But to tighten up the code I thought a counter was in order. So I tried a while loop.
[Code]...
A few oddities, for one this makes a total of 11 sheets. I thought this would make a total of 7. The first 3 then adding 4 from the while loop. I thought a counter starting at 0 then going to < 4 would add 4. Also I'm getting an error, noted in the code, it expects an end of statement. It doesn't like the +=. I'm trying to add to the sheet name/number of Taroko #. Maybe it's trying to start at 0 there. So I'll initialize the namectr to start at 2. No still doesn't work.
I think my syntax is simply bad for the statement..Sheets("Sheet4").Name = ("Taroko # " + nameCtr += 1) ' error here also tried & instead of +.

This is the standard way of checking if URL exists [code]....
return true; } catch (Exception ex) { return false; } But my problem is that we have to check it for around 100 URL's. It takes more then 2 minutes to check for all as it is trying to get response of all of them. Is there any way that we can check if URL exists without getting complete Response so that total response time is less.

I have 300+ excel files that need to be combined. There are 4 different types and in 4 different directories on my network. I need to copy the data out of each one and combine the data into a new single workbook (1 for each type). I have come up with a solution that does MOST of what it is supposed to do. Only problem is I can't figure out how to have the paste operation go to the same single workbook. No matter what I have tried it opens a new copy of excel to paste into everytime. Here is what I have so far.[code]...
