VS 2005 - Saving Records In XML Files
Jan 22, 2011
I am trying to learn XML, for which i have created a simple Employees Program. I want to save the records of the employee in an xml file, so far i have the following code:
vb
Private Sub SaveRecord(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim XMLSettings As New XmlWriterSettings
XMLSettings.Indent = True
XMLSettings.IndentChars = " "
XMLSettings.NewLineOnAttributes = True
[Code] .....
This is only working for a single record, How should I insert more employees records within this xml file?

A query concerning opening and saving a file.i have two commands, one the opens and another that saves [the same file].i'm using the StreamReader and StreamWriter methods.issue is this:if i comment out the open code, the save works fine.if i comment out the save code, the open works fine.if i let both run together, i get an error, usually with the save saying that the file could not be accessed. note, before anyone asks, i do close the file after saving or opening what could be the problem? open works fine, because it usually happens prior to the save, and then save process cannot access the file..?

I have a datagridview on my form which is not bounded to any database table.The datagridview is only used for data entry. When the user has populated the datagridview and click the save button, I want to be able to save all the rows into a table in my database.At the moment, if more than one row is populated, my code is saving only the second row of the datagridview and everything else is ignored. If only one row is populated, it works fine.I am using Oracle database 11g and a store procedure to insert the records. Below is my code.
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim cmd As New OracleCommand("MHMS_Package.Insert_Service", conn)
Dim strCmd As New OracleCommand("MHMS_Package.Insert_Service_Details", conn)[code].....

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]

My program runs with no errors, but the actual .accdb file does not reflect changes when I make them in the running program. Also when I fill in the text boxes and click the "Add New Item" Button, the "ID" text box displays a -1. "ID" is the primary key in my Access Database.
Imports System.Data.OleDb
Public Class addMemberForm
Inherits System.Windows.Forms.Form

I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:
[Code]...
There are no problems during build or run time, but I do not see changes to database after the program runs.

It's saved as google2.txt.(it will contain many of the same links as google1.txt & i do not want to re-visit those links)How can I reference google2.txt to google1.txt & end up with google-new.txtWhich will only contain NEW links, that are not in Google1.txt

I have a slight problem understanding how the following code works, it's specified in an example I have that the code is to check if FileName is a valid path for a text file and other things of course but I'm just interested in that part(checking it's a valid path). Here's the code:
Method save()

I have a routine which populates a DataGridView. I generate the data on the fly in arrays and the populate the datagridview simply by saying
For each Row in DataGridView1.Rows
DataGridView1.Rows(row.index).Cells("PastColumn) = Array(row.index)
Next
I am not saving the data to log files. I only display the results at the end of my routine. When I close the project the data is lost.I am trying to understand why one would bind data. Would you do this in the case where you are saving the data to a file and you want the datagridview to update when the file is updated or loaded again at another time?

We have to learn VB.NET for the semester, my experience lies mainly with C# - not that this should make a difference to this particular problem. I've used just about the most simple way to save a file using the .NET framework, but Windows 7 won't let me save the file anywhere (or anywhere that I have found yet). Here is the code I am using to save a text file.

Any way to save all files that are being downloaded trough the WebBrowser I've made in my Visual Studio 2010 to a specific location, by letting user to chose option save file without knowing where it saves. Or maybe to don't show the "save file" thing at all.

I am working with .net resources using LINQ to XML. I want to edit some resources, so I coded this:
Public Shared Sub AddTranslation(ByVal filename As String, ByVal name As String, ByVal value As String)
Dim items = From translation In XElement.Load(filename).Elements("data") Where translation.Attribute("name").Value = name
[Code]....
This seems to work, and even when I debug VisualStudio says that the file changed, but actually it doesn't. I think the problem is in the Save() action, but I don't know other way to save it...

I'm having some problems with people saving text files using my program, but only people using Vista. Since I don't use Vista myself, I'm not sure what this is but it's not a problem on any machine running XP.
Note that my file saves just using the standard Savedialog box and Filestream/Writeline commands.
From what my customers are telling me, the save dialog comes up fine and there is no error as the file appears to save, but when they look for the completed text file, there's nothing there.

First time user on here, basically have been teaching myself VB and I enjoy it quite a bit! Basically I have a program now that has the File Drop-Down Menu with Open and Save options. I want to open and save in a .txt format. The open command will need to place the text in TextBox1 ; and the Save command will need to take the text from TextBox2 and save it as a .txt. I have gotten to the point where it will save it to a specified .txt file, but I would like the user to be able to "browse" the computer for where to open from and save files to.

I have to create a school reward system. Currently i have written code for creating user accounts and logging into the system. I have been able to write to the file i need to and i have been able to log in. However i can only log in for the first saved account. when i hover over the stored variable whilst stepping through it appears that unnecessary gaps have been added to stored information...User.stored username is the data structure type that i have stored information as...
user.storedUsername = " TestStaff "
I believe it should be like this:
user.storedUsername = "TestStaff"

I am working on saving excel objects to a directory of my choosing. I am able to use a folder browser dialog to select the save location and the saveas method within the excel interop and i am able to create a file in the folder i select with the name i choose. The issue is that when i later go to open that file it is blank. no workbooks no worksheets etc . Just a seemingly blank file in the proper location with the proper name.
It should be noted that if i single click on the report icon to open it the microsoft browser window does show a tiny preview of what seems like the correct report.
eapp.Worksheets(1).SaveAs(FileName:=patient_frm.savefolder & "Lateral Postural Analysis")

I have ALWAYS used the SQLDataSource to update my records in my SQL Server 2005 database, so i am not really sure how this would be done in normal code. I am using VB.NET but if you are a C# developer and want to show me some code that is more than welcome as well.
I am using ASP.NET 3.5.My user will see a page with 5 Text boxes with their contact details in. Those details I will get from a SQL Server DB and when they go and change the text in the text box and click submit, it must then save the changes.
This is very easy with the SQLDataSource but how can i code this myself?
