The purpose of the program is for text to be dragged between boxes to move assets around. I've managed the drag and drop functionality but need to persist the text in the text boxes once the program is shut down so that when reopened, the last location of all moved text is still present.
I've tried the easiest to understand suggestion to get me started but when I build and publish the program it says that I do not have access to the file to save the values!!
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim txtpersist As IO.TextWriter = New IO.StreamWriter("C:UsersHPDocuments

Inheriting from the System.Web.UI.WebControls.WebParts.EditorPart class I have been shown that it is possible to expose a public property in your VisualWebPart that when updated through the EditorPart will be automagically persisted in sharepoint.
The problem I have run into is saving strings and integers works great but when I attempt to persist the value of a collection such as List<String> the object is not saved.
The code looks like this.
Public Class MyCustomEditorPart Inherits EditorPart Public Overrides Function ApplyChanges() As Boolean
Alright, so here's my basic ASP.NET page setup: I've got a page with a GridView that has ContentTemplates in it. You can add a row and edit/remove rows at any time. There's a "New" button that creates a new row.
All of this data is bound to custom data objects. So if I have a GridView of "People" and each row has "FirstName", "LastName", and "Gender" (with TextBox and DropDown controls), I then have a "Person" object which has public properties for "FirstName", "LastName", etc. I have the binding set up correctly, and I can push data into the GridView from the object, and I persist the object with the Session variable. My page lifetime structure looks something like this:
Page_Load: Loads the List(Of Person) from Session() Any events fire, and modify the List(Of Person).
After any event, the List(Of Person) gets saved back into Session(), and is then DataBound to the GridView (and any subsequent fields are also DataBound, such as the DropDownList.
My question is: Whenever I fill in rows in the GridView, and then add a new row (there is no database saving going on whatsoever), my fields clear out and don't persist across PostBacks. So, how can I persist my custom data objects with databinding across postbacks?
If InputBookinglength.SelectedValue.ToString = "2" Then Dim paramstring As New StringBuilder If Session("SelectedDates") IsNot Nothing Then

This code works fine when selecting multiple days in one month. But when you switch to display a different month, the previous months selections are lost. how to persist the selections when the visible month changes.
In a MDI WinForm I want to save each child window position and state, per application user, that is different by the logged in Windows user. My application has its own users; so I won't use the user settings like my.Settings... etc.One option is to read/write directly to the database, but I don't like the idea to access the database for something so trivial as the windows positions. The plus is that I could store that information independently by the machine where the user works, wherever she logs in, her preferences will be remembered.Another option, that I'd like to follow, is to use Xml to store that information in a file locally on the user's computer. The structure could be something like:
how this could be done; maybe using Linq to Xml? I've found I can write something as simple as
Dim formPos As XElement = _ <User><%= My.Application.connectedUser.id %> <form1>[code].....
2) How to write the XElement when finished building it. Should I use an XmlWriter.Create? Hot to pass it the XElement?
3) What happens when in the Xml file there's already a node with the same name, I want to overwrite the previous user settings if they are already there, but not append to the file, nor rewrite the entire file, of course.
Does anybody know how to persist (save and recall) a structure array when using a custom control? I don't want this data to show up in the properties window but it needs to be available "behind the scenes".
Right now, I'm writing the information to a file but this causes portability problems and may trigger the UAC.

How can I persist this without writing to a file? Should I save it to the registry?
(I've answered the question below with a hack. I'm fairly confident in it unless MS change the way that codedom serializers the designer code.)ETA2:I've worked out what is going on. I wondered why sometimes it would work and not others. It boils down to the name that I give to the internal property and the collection.If I rename the property 'Annoyance' to 'WTF', it will serialize correctly because 'WTF' is, alphabetically, after the name of the collection - 'InternalAnger'.It looks like the serializer is creating instances of objects alphabetically and needs my internal property to be created by the time it comes to create the collection.I can fix this with a rename, but that's a hack and I fear that writing a custom serializer is a big job - which I've never done before.ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code:
Public Class Anger End Class Public Class MyButton
This is the only way I know how to obtain the info I need for this equation but if generated again with no input from the textboxes I get an error. Is there anyway to bypass this if its generated a second time with no inputs?

I want a text in my textbox in gray that dissapears when the user clicks in the textbox.I am not sure if that is a good enough explanaition so here is an example:You often have search boxes on websites or application.In the searchbox there often is a text like "search", "keyword", "type here".As soon as you click with your mouse inside the textbox it dissapears.I could make this in code but I was wondering if there already is a textbox property for this?

I cant seem to find any link or topic regarding my problem. I have 2 forms in a project, form one has labels and adjacent combobox while the other form (form 2)has textboxes with adjacent combobox. I am supposed to change the text property of the labels using textbox entry from form 2 and add/delete/change combobox contents in fom 1 using entries combobox at form 2.
im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.
Here is the code that i used for this:
listarrays = name of listbox textbox1 = name of textbox
l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer
Dim text As String = Me.TextBox1.Text For Each item As Object In listarrays.Items If item.ToString = Me.TextBox1.Text Then
[code].....
use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?
I am trying to bind a textbox to a binding source (using the IDE DataBindings Editor) and it works fine except for one thing: if I delete the text I get the subject error. What I want to happen is the datarecord field be updated to a dbnull value -- how do I get that to happen?
