I found out there are ways to Select, Insert, and Update Excel file by using OLEDB. But the limitation is that we can not delete a record.My idea is to delete row (instead of record). The question is how to programmatically delete row in excel, by id selected?I want to delete the row where id = 3. I can grab the id, but have no idea how to delete the row which contains the id 3.

I am having some issues with an application written in VB.net.
As part of a routine, an sqlce database gets backed up before the routine then if an error occurred gets restored. I am using system.io methods copy and delete.
I have released all the objects (connections, commands, datareaders) asscociated with the sqlce database by disposing them if they are not nothing. I also do a GC.COLLECT however when my delete command runs, an error message says it is open by another process. The PROCEXP.exe process explorer tool says it is attached to 4 undefined processes. After a while in debug mode, these clear and I am able to delete the file. However this is not acceptable as my program cannot "wait around" until they are released! I was under the impression that object.dispose forced an immediate disposal rather than waiting for the garbage collector to clean up (if you were just to use object=nothing), but still there appears to be a finite time before these objects are released.
My question is, is there an alternative way of checking (programatically in vb) for what is holding open an sqlce database (or in fact any other file for that matter) then killing these processes?
I created a custom control and add it to a form programatically.
The user can add and move them all over the form.
The problem is when I want to clear the form of my user control I don't know how.
I created an array of my control called ctlCorkNotes
Say I create ctlCorkNotes(1) and now I want to delete it.
How do I do this so it is gone and would have to recreate it to show up again?
Are there any way to do so? I prefer to use VB.NET or Java and try to avoid to use VBA.

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.
View 3 RepliesWhats 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#
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?
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

View 1 RepliesHow do I left justify my columns in Excel programmatically in VB? I have a VB program that is writing an excel file based off of certain information. I have tried using:

View 1 RepliesI'm reading data from Excel and processing the file line by line.
If the process succeeds then I need to delete that row from Excel and save it. If it fails, then continue with the next line and so on.
Initially I used OLEDB to read data from Excel, but by using this I cannot delete rows.
I think we can solve this by using COM component.

I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...
Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).
If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.
I am trying to delete a worksheet from an Excel workbook. Here's my code snippet

The Strange thing is that Microsoft API reference says that it would produce a Boolean, but it doesn't as it is a Sub and not a function.
