I have a workbook (Workbook1) that runs through some steps using visual basic, which ends up opening another workbook Workbook2). Once Workbook 2 is opened, I need to copy a section of data from it, into Workbook1 int a specific worksheet. I was able to do this by recording a macro, but the challange is, the name of Workbook 1, and Workbook 2, will vary by User. When I created the macro it uses the files as they are currently named. The section of code is below.

i have a scanner set up which scans .bin and .iso files and returns the crc32 checksums (then displays various info based of that etc)
Im looking into adding support for .rar and .zip files, so the end user wont have to extract there files to scan them, how ever that adds to many variable for the crc32's based of what each persons compression is etc. So what about scanning the file inside of the rar/zip file.
So would it be possible to scan a rar or zip file, and get the crc32 of the .iso/.bin located within that archive?

I had a related question running on this in a different thread,but I was told to start a new thread since the original had gotten off the original topic. I am trying to scan multiple pages from an Automatic Document Feeder Scanner and combine them to a singlemulti-page tif file. I am using two different third party libraries to do this.The first library I am using is to scan the documents. It saves the files to the local hard drive as single page tif files. This library returns the file-names as they were saved on the hard drive. This part seems to be working as advertised. The sourcefor this including a video on how to use it is at:
Dim FileNames As Collection
Dim FileArray As New List(Of String)
Dim Mergename as String

what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

I know how to write and read files but I can't seem to add 1 to an existing file.
This file currently contains "10" but when I click a button I want it to +1 to that number.
I've tried a.WriteLine(+= 1) but it gives me an Expression Expected erorr which I don't get how to fix or what's wrong with it.
If anyone can help me fix or give another code that +1 to the existing numbere.

Im creating a login system that allows staff to clock in using a 5 digit code. Staff members can also use the "add an employee" function to add a new employee to the Random File.The problem is, everytime i try to create a new employee and hit the save button, the new record writes over the existing records, one by one, everytime the programme is stopped and started up again.
My Question is: How can i get the new record to be saved, without deleting existing records,
Here is the save buttons click method:FileOpen(fileNumber, "C:employee.dat", OpenMode.Random, OpenAccess.Write) 'open the file with Write Access
myEmployee.name = txtNewName.Text 'adds the name
myEmployee.id = txtNewID.Text 'adds the ID
FilePut(fileNumber, myEmployee, n) 'save to the file
FileClose(fileNumber)

Below is a link to a small zip file with an existing VB (2005 I think) program. [URL] This programs detects if the OS is Locked. I want to make a small edit, and have found the required code for the edit, but I have been unsuccessful at attempting to implement the code. As I said this program only detects windows locks and unlocks. What I want to do, is set it to run an exe when I lock my computer. Doesn't matter what the exe is, just a very basic program.
I however have not been able to find where I need to insert this code. The zip file contains about 6-8 files, I thought I found the if statement where I needed to drop the code but even when I added it to every if that seemed probably I couldn't get any result. what if statement the code I need to add should go into. honestly all I need, I can handle the code past finding that.

I want to open an existing VB class file, add a few properties and close it again.
Simple enough, I thought: Take the CodeDom, a VBCodeProvider, parse the code (using the Parse-method), then identify the location where I want my stuff added (doubtless using some nifty LINQ expressions), add a bit of code and then have it generated and here we go.
Now I see that Microsoft apparently added the Parse method only for the fun of it but never implemented it.
What's the story here? Can I only generate code from scratch? Is it not possible to load existing code?
