View 6 RepliesI have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

View 6 RepliesIm 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?
I'm creating an app that will be run via scheduled task, it will save an XLS file with the following naming convention:'S14-PROORDEREXP-Thursday' (the Thursday will change depending on what day of the week it is)I have the following line of code to save this excel file:

If gstrJob = "S11" Then
xlWorkSheet.SaveAs(gstrFilePathS11 & gstrFileNameS11 & gstrFileTypeS11)
Else

this will work fine the first time this scheduled task runs and there are no existing files but at the end of 1 week when I will be overwriting the existing files, how do I tell the application to overwrite the existing files without waiting on a yes prompt from me which it does in debug mode?
I have a series of .DAT files I need to read into vb.net and then parse the data into a format that can be easily read into an SQL database that already exists. Would I be using a StreamReader object? Or is there a different way to go about this?
