I am trying to populate a form from a list of values. I am fetching data into a recordset. I have a textbox that displays the date, however, when I try to assign a date value I am getting the error message that I cannot set the textbox value to a textfield. Is there a way to assign the date value to the textbox?

My screen tends to seize for a few seconds while the list boxes are populated.I moved the call to the List Populate procedure to the form's shown event.This improved the performance slightly but not enough.Is there a method whereby I can ensure the form is fully loaded and displayed before the lists are populated?
View 6 RepliesI have the following "contact" data (exampled below) stored in an xml file.I've created a frmContacts windows form and placed a list box control inside it.I'm new to the list box but plan to have the users manage the list by letting them add, delete, and pick from it. For searching there should also be a sort function/button (by last name then first name).If the user deletes from the list the corresponding data in the file will be deleted.If the user picks from or adds to the list, I'd like to find the best way to populate the corresponding data elements on another form (i.e., in their respective text boxes). This will include the ability to edit/save from this other form too.

Let's say I have 50 cars and I created 6 attributes for each of the 50 cars (therefore 300 total variables and values for those 300 variables). These attributes are created and valued based upon the following structure:
Car1Name = "Dark Red Car"
Car1Color = "Dark Red"
Car1DoorCount = 4
Car1Cost = 10000
Car1Appeal = 10
Car1BoughtStatus = False
Car2Name = "Bright Red Car"
Car2Color = "Bright Red"
Car2DoorCount = 4
Car2Cost = 11000
Car2Appeal = 8
Car2BoughtStatus = True
and 48 others of similar structure/syntax
How do I take a a module with these variables and values and populate them into a listview within a form such as Form1 and ListView1 without continuously going into listview's UI and manually entering the data? The goal is to show the USER a list of 50 cars, their color, door count, cost, appeal, and purchase status.
I'm working on a project for personal use to make my life as an IT administrator a little bit easier. (Yea right)So basically, i'm creating a windows application with a form. On this form, it has a button, and a listview.When they click this button, it will load all "Windows XP run commands" into the list view. I also, have a on-click event to capture a click on certain lines in which it will automatically open said run command, or shortcut.
Here is an example of what I am working with so far. (It populates correctly, and the clicking event works like a charm. However, i'm just looking for a better way to clean this code up, or maybe, a better way to go about everything).Once done, I will populate this to the codebank if there isn't another similar thing out there.
On to the code:This is what I have for the form_load event
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
With ListView1
.View = View.Details 'Changes the view to "detailed" view
.LabelEdit = True 'Allow user to edit text

View 1 RepliesI'm very new to VB.net/Vb2005. I just finished my first semester learning VB and I'm working on a few personal projects to solidify/increase what I've learned this year. Right now I'm building a simple inventory application that will keep track of individual users at my job.
The problem I'm having is in trying to populate a comboBox with items from a text file. My goal is that when the application loads, a comboBox will be populated with the names of users(located in a text file.) Upon selecting a user, the application will read some other(like users name, windows version, computer name, etc) data from another text file and populate the applications text boxes with that information.
I know how to go about building most of the application, but the problem I'm running into is how to use a text file to populate the comboBox. If I use an array or a collection for the comboBox data, then the user list will be lost each time the application closes. Also, whenver a new user is added, that data will be lost, because the collection or orray will be lost each time the application ends. Also, I don't want to use a database for the program, just a simple file.

I'm using a Datagridview to fetch information from an XML. Each row contains a separate entry. I can read from and append to the XML database, but I want to:
A) Be able to save any edits made in the database to an XML file.
B) Store and fetch a collection of possible variables to populate a list box.
A should be relatively easy, but I don't know if B is. The XML database will contain hex values that can be written to predefined offsets, and each could be any number of bytes long. So one entry in the XML/Datagridview database could read "00,0A,0B,0C", where commas separate available write values, with each possible value being another line in a listbox. When a value is picked from the listbox it will be written to the XML.
I don't want to have to make <ListBoxValue1>, <ListBoxValue1> in the XML for each possible entry, so I'm hoping there's a more efficient way.
If you're interested in what I'm making, it's a hex editor that loads descriptions of offsets from an XML, then loads the values for each offset from a file. Here's a screenshot.
I am trying to populat a treeview with nodes that are the values of a column in a datatable. I have managed to get the correct number of nodes but the text is not displayed next to the nodes, there is just a 3 shape but the other way round and with square corners shown.
The code is below. I would like to have these parent nodes populated on the form load and then (i think this is what i have read) to be quicker i would like to then load the childnodes once a parent node has been selected, as i don't want to load the whole database on form load or when the form is refreshed.
Here is the code with more dtails below:

I'm attempting to add comma delimited values to a combobox. The problem is I do not know if this is the best way to split the values into the combobox. Is there a more cleaner/efficient way to do this?:
Dim toread As String

Dim textdelimiter As String
textdelimiter = ","
Dim splitout = Split(toread, textdelimiter)
Dim i As Integer
For i = 0 To UBound(splitout)

View 1 RepliesIs there a way to get an integer value from a DataRowView? I have a list box with datasource set to a binding source. I would like to be able to do this:
dim num as integer
num = lstBox.SelectedValue
But I receive an InvalidCastException:
Conversion from type 'DataRowView' to type 'Integer' is not valid.
This is how I fill my list box:
myDataAdapter("SELECT CustID FROM Customers", cn)
myDataAdapter.Fill(myDataSet, "Customers")
myBindingSource.DataSource = myDataSet
[Code]....
I have one list box this works for and one it doesn't, so far. The only difference that I notice is: the one that works, the Query in the data apapter retrieves and auto number from my access table, the one that does not work, the Query in the data adapter retrieves a number.
Or, is there another way I should go about this?
The application that I am trying to make is a form with a list box for CustID, OrderID, ItemID, and others. The CustID is from table Customers, OrderID is from table Orders, and ItemID is from table Items.
I have a dropdownlist that I want to populate with a specific value and specific text. I'm not using a datasource but I am manually making a connection and retrieving data in code.

//connection string etc goes here

I'm trying to get a listbox to populate a list of processes that are neither running nor in the "blocked" list. This code is in a timer, so it also checks if the process is already in the list.

It is strange because this is populating the list, but adding the same process over and over again, even though I seem to have the checks in there.
(This a follow-up to a previous question. VB.NET WPF NullReference Exception)I have a TreeView with a parent node and two children node. Each of the nodes contain a checkbox stored in a TreeViewItem. I want the two children node checkboxes to be set to IsChecked=true when the user checks the parent node and I want the two children node checkboxes to be IsChecked=false when the user unchecks the parent node.
I have a for loop in which the child node checkboxes are stored in a list. The parent node's checkbox check/uncheck event should iterate through the child node checkbox list but I am having a problem with the childCheckboxes list in the chkbox_AllChecked function (the parent node's checkbox check/uncheck event). For some reason the list is empty. I think the problem is how I try to populate the list while inside a For loop. Can anyone explain what I am doing wrong?

I want to populate a Combo Box with a list of names and from that have the contact information (address, phone, email, ect..) populate a series of textboxes. The list is roughly 20 names, but it could grow to a hundred or more. Since the contact information changes periodically, I would like a very easy way to maintain it (Excel or Access).
