I'm using Visual Basic express 2008.The application I am working on is the first major project I have ever undertook with visual basics. The application is a launcher for a private server for world of warcraft.I have a menu bar that pulls the file path of the wow.exe and puts it in a hidden textbox, I then have another option that saves this text to c:wowexe.txt. All of this works GREAT!
How can I read the .txt file to end and return the information stored in the .txt file to this line of code.
Dim RetVal
RetVal = Shell("This is where I need the data from the .txt file to be seen", 1)
If your wondering why I don't just type in the path of the .exe, it's simple, not everyone installs World of Warcraft on the C drive.

I am making trying to make a program that can read the file information directly from a specified file, but I am having a lot of difficulty reading things like file comments.An example of this can be found in windows XP when you alternate / right click on any file and click on properties. You'll get a lot of extra information.Now I have a few questions about this.
1.Can this information even be read in VB.NET
2.If so how
3.If not do I need to create some kind of data file to store the file information
Here is what I did so far

I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

Application using ado.net
When reading data from an excel file the driver tries to detect the data type of a column based on the contents of that column.
Once it's decided on the datatype then data that is not compatible with that datatype is simply ignored and returned as Null when you read that column using ado.net
For example if most of the column contains numbers then the occasional cell containing non-numeric data is returned as null.
Is there a way to force it to always return all data as text no matter what the actual column contains. ?

I have a program that I wrote that uses a system generated excel file from a remote system.
[Code]...
The issue I'm having is when I query the system generated excel file, it is not returning the last row. If I open the file in Excel and then save it, It returns all the rows. Since Windows 2008 64bit does not allow control via Excel to the file, I have to query the file via Jet provider or Odbc provider. I have tried using the Jet provider and the odbc provider.How do I get all the return all the rows with the system generation file?

I have always used Excel.interop before but I thought oledb would be simpler because, for this application, I only have to read the data which it can't seem to do. It accesses the file alright because I can't open the file while I am at a breakpoint. It attempts to read the file because oExcelReader.fieldcount = 14 which is correct. oExcelReader.hasrows = true which is not correct. The line where I use getstring(1) errors out and says there is no data for this row/column.

I'm creating a program and it is paramount to its functionality that it can open->read->close a Microsoft Excel (.xlsx) file.Now, I've searched the forums with the keyword "Excel" and found a lot of stuff in many programming languages, none of which were any use to me.
I should pinpoint that I'm not that good at programming as university takes all my times, but every summer (like this one) i really enjoy tackling my problems via programming.[code]...
