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#
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?
my VB.Net desktop app writes to an Excel file. I need to set the style to a row. I can read a style of one row, but am unable to set the style in another.
[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 am working on some code to take a csv file, save it as xls, then chunk the data down into a series of new worksheets. However I am having problems with saving the changes and I really can't pin it down. The code is as below

I'm trying to import data from an Excel file into SQL server. However, the Excel file's format is not recognized by SQL Server. In fact, when I open it and try to save it, I get the following message:<filename> cannot be saved in the current format. To save your changes, click OK, then save it as the latest format.When I do that manually, it puts it in a usable format. However, the automated process I'm trying to build can't save it without intervention. When the VB in my SSIS process gets to it it brings up a save window, and I have to click the "Save" button and then the "Yes" button to replace the existing file. I'd strongly prefer to have this automated. I've have tried using the SendKeys.Send("{ENTER}") code, but it brings up this message:SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.I've tried SendWait, but it just seems to hang. I don't know how to change the application to handle error messages. I have also tried saving the Excel file as a new file with my VB code. However, as a new xls, xlsx, and csv file it still wasn't recognized by the import. I've only had success when manually saving it. In the SaveAs code I have been using, I'm only using the FileName parameter. I can't get any FileFormats to work or be recognized. Note, though, I'm opening the app and worksheet as Object variables. I can't add the Excel component in the Add Refrence area because only the .NET tab is there. I don't have a COM tab. I haven't asked if/how to get access to it, though.
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 ?
I am trying to create double and number format cells in excel using NPOI library. I used code like Dim cell As HSSFCell = row.CreateCell(j) cell.SetCellValue(Double.Parse(dr(col).ToString)) In excel numbers are aligning right but when I check format it is showing in "General" then I changed my code to like below
I have an Excel file that downloads automatically, but for some reason the binary XLS file contains some garbage HTML text at the end of it.
When opening the file in the Excel application, it shows a warning but proceeding will automatically remove the garbage HTML text.
However, I need to open the file programmatically. When doing so via
Dim wb As Workbook = Excel.Workbooks.Open(ExcelFileName)
It throws:
Exception from HRESULT: 0x800A03EC
a) Get Excel to perform a similar action as if I manually opened it and remove the garbage HTML automatically. NOTE: Tried setting the XlCorruptLoad.xlRepairFile parameter and it didn't work.
OR b) Remove the garbage text from the XLS binary file (FileStream?) and resave it before attempting to open the file with the code mentioned above.
The garbage html always comes at the very end of the file and starts with
I know album name is usually to music files & stuff probably but I guess album is what I need to categorize my video files correctly in Windows Media Player as it does organize my music files correctly when using album name & title. Anyways, these files I just want to change album name at the least & the description is something else I'd like to change on them as well. These files when I right click & go to properties then over to the details tab will show all the things like it usually does, but it will not let me change them. I am guessing this has to do because they are protected type files but I just want to change some things so they display correctly in Windows Media Player.
It already lets me change attributes inside Windows Media Player & at the bottom pane of the screen in explorer when the file is selected of attributes the file already had, but it won't let me add in the album name & description since it didn't start with one. I don't want to get rid of the protection on the files to be able to add these attributes either as I thought that was illegal or something, plus I don't want to download another program I don't have just to do this, whether it be a protection remover (which I said above, I think is illegal, even if it wasn't or isn't, I still wouldn't want to do that anyways) or even a thing that can change the attributes for me I wouldn't want to download since I just don't like downloading things that I won't use often, even if it's easy to remove & everything.
Since I already have VIsual Basic 2010 Express Edition installed I would just like to code something to change these attributes programmatically. It can be a simple textbox which is the location of the file and a button which changes the album name and description to "Just Text" that way I can put in each file I want to change & then click a button and it will be good from there. I will be able to change the variables after they are there to what I want after that from explorer or windows media player so I don't care for having textbox to change album name & description per file as I can just do this in explorer afterwords to what I want. By the way, files are in .wmv file format.
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.
