Hey I need some help. I cant figure out whats going on. I'm working on a Restaurant Management System, and I can create an employee, but then when I try to create another after I created one, it wont work. My Post Tools aint working so I'm gonna wing it on the CODE Tags. So sorry if it's messy. Maybe big_k can wrap em up till I figure out my problem. Here is the code that saves the employee info to file, and the code to show a message box if that employee number file already exists.

(Toggle Plain Text)

 Sub Save()         File.WriteAllText(My.Application.Info.DirectoryPath & "\" & number & ".emp", _         "-Employee Name Info-:" + vbCrLf _         & first + " " & middle + " " & last + vbCrLf _         & "-Employee Address Info-:" + vbCrLf _         & address + vbCrLf & city + vbCrLf & state + vbCrLf & zip + vbCrLf _         & "-Employee Info-:" + vbCrLf _         & bday + vbCrLf & hphone + vbCrLf & cphone + vbCrLf _         & "-Employee Social Security Number-:" + vbCrLf _         & ssn)         managercp.txtfirst.Text = ""         managercp.txtmiddle.Text = ""         managercp.txtlast.Text = ""         managercp.txtaddress.Text = ""         managercp.txtcity.Text = ""         managercp.txtstate.Text = ""         managercp.txtzip.Text = ""         managercp.txtbday.Text = ""         managercp.txthome.Text = ""         managercp.txtcell.Text = ""         managercp.txtssn.Text = ""         managercp.txtnumber.Text = ""     End Sub      Sub EmpExists()         MsgBox("Employee File with that number already exists. Please specify a new number, or delete the existing Employee File.", _         MsgBoxStyle.Critical, "Employee File Error")     End Sub

Here is my code for the Save Employee Button:

(Toggle Plain Text)

  Private Sub save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles save.Click         If My.Computer.FileSystem.FileExists(My.Application.Info.DirectoryPath & "\" & txtnumber.Text & ".emp") Then             Employee.EmpExists()         Else             Employee.Save()         End If     End Sub

Like I said everything would work, if I only wanted to create one employee file. But it wont let me write to another file. When I click save, it erases the text boxes, and if I try to create a file with a duplicate employee number, it handle the error. It just wont create the file. I typed in my info for all the info i needed, clicked save, the text was "" in the textboxes, but no file was created. Am I missing somehtign in my code, guess I've been looking at it for the past hour and a half trying to see it, but i don't. Either I'm tired, or I can't program. I'll let yall be the judge of that. But just help me, if ya can. Thanks

Repost your code with line breaks so it's legible and I will take a look.

When you write the 2nd file are you updating the number variable with the new number from txtnumber.text? It doesn't appear so.

Won't this mean that you trying to create a file that already exist, since the number is used to in the filename?

What was this error it handled?

mattireland · Aug 30th, 2007, 4:11 PM

What I don't understand is that this has got 102 views and yet only (now 5 replies)...

Sorry for the OT nonesense...

He is saying that part of the program worked correctly. When he attempted to create a duplicate file "the error was thrown" AKA "it handle the error"

Yes that is BS, I completely agree. Usually I use the forum to recieve help and insight on my own problems, but when I see a post like this just sitting around it bothers the hell out of me that no one tries to help. It happens to me all the time.

bigguy · Aug 30th, 2007, 10:09 PM

I think the biggest reason no one helped was because of my damn code tags thanks to avant has now been fixed though. But yeah that EmpExists sub i have created shows the message box incase they already have a employee file with that same number. I guess it really aint an error, but sorry for the confusion.

Also kilo, about the updating this is what I am using.
File.WriteAllText(My.Application.Info.DirectoryPath & "\" & number & ".emp" << I specify it to write to number.emp

Is that kind of what your asking?

No not really... I meant this

(Toggle Plain Text)

number = txtnumber.text
File.WriteAllText(My.Application.Info.DirectoryPath & "\" & number & ".emp")

bigguy · Aug 31st, 2007, 1:47 PM

Yeah I have that I just didnt post that part, cause I didnt think it would help any. But yeah all that first middle and last stuff I have.

Dim number = managercp.txtnumber.text
Should I have
Dum number As Integer = managercp.txtnumber.text.tostring?
Maybe try that
