Writing Data To An Existing Excel File?
Mar 15, 2010I'm working on a project where I have to allow users to write data to an existing Excel worksheet (by entering the data into a form created in Visual Basic.NET). I've created a form that allows users to enter data such as the following:
Name (First, Last)
Mailing Address
Email Address
Gender
Age
...and so on. I've programmed the data to be sent to the Excel file upon clicking on the Submit button in the form itself. I've also created the Excel file and placed it on my C: drive, but the problem I'm having is trying to send the data from the VB form to the Excel file itself. Can someone please show me some sample code or point me in the right direction as to how to get the submitted information from the form to save into the Excel file, please?
I'm trying to get the information to show up in rows and columns in Excel like the following below (the dashes are just to show that the information should be in rows and columns):
Name--------------------------Mailing Address-------Email Address-------Gender-------Age
John Doe---------------------2300 Jackson Street-------- xxx@xxxx.com-------Male---------17

Jan 19, 2010Im 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

Writing Array Of File Names To Text File
Mar 11, 2010I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.

Link To A Small Zip File With An Existing VB
Sep 23, 2010Below 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.
Open An Existing VB Class File?
Jun 30, 2011I 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?
Overwriting And Existing Saved File?
Nov 3, 2011I'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:
VB
If gstrJob = "S11" Then
xlWorkSheet.SaveAs(gstrFilePathS11 & gstrFileNameS11 & gstrFileTypeS11)
Else
[code].....
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?
