the project i am currently working on has a form in it that has quite a few objects that take a couple of seconds to load. Because of that, if i simply use the .show command, the form shows up, but there are a bunch of blank white boxes where the content is still loading, how can i have the form not become visible until ALL of the contents and images inside are fully loaded?

I'm in the process of adapting a current program that I've created to automate it. **Current State***User selects an excel file and the contents are loaded into a DataGrid User can select which environment to run their query against (stage/prod) Program completes processing and updates datagrid with new values User can export datagrid to excel What I'd like to do is centralize the program on one computer and have it monitor a network folder for creation of a specific file type (*.xls or *.xlsx). If one of these is created in that folder then I want to add that file to a queue for processing. Once done processing I want to send the results as an attachment to an email to the user that created the file. After a file is processed I would like to remove it from that folder as well (into a diff folder of completed items).

1. How do I make it so a listbox displays a files contents once loaded?
2. How do I save a textboxs text?
3. what does this error mean?
An error occurred creating the form. See Exception.InnerException for details. The error is: Failed to initialize because CategoryName is missing.
I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

View 2 RepliesWe are looking to make a final decision on our Mocking framework. After trying several, I have fallen in love with Moq. I also love TypeMock - but because we are in the early stages of implementing TDD across the team, we do not want to make such a large investment quite yet. We are using VS 2008 now and are going to move to 2010 as soon as it is released.
So after doing much research I have decided on Moq because it's nearly as good as TypeMock and has super clean syntax, etc. Now here's the problem/question: we are mainly a VB.NET shop but are using C# for all of our CRM implementation code (plugsins, etc). It seems Moq only fully supports C# due to VB.NET lacking Lambda sub routines. Can anyone confirm that when VS2010 comes out Moq will work fully with VB.NET in its current version?
Is anyone here using Moq with VB.NET? w/ 2010? We need to make this decision asap, as we are under tight deadline and do not want to change frameworks again (went from NMock to TypeMock and now want to make final decision and move to Moq) or have 2 separate ones per language...

View 3 RepliesI have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

I have a form in a Windows form application that I want to display on top of a main form, close it, and then immediately show a dialog box using MessageBox.Show(). But the first form is still showing when the message box is shown, and it does not disappear until I click OK on the message box. I tried waiting to show the message box in an event handler for the form's VisibleChanged event and even calling Refresh() on both the form and the main form. Is there a way I can determine when the first form has fully disappeared before displaying the message box?
Edit:Here is some code that demonstrates how the forms are being shown.
static class Program
{
// The main form is shown like this:
static void Main()

View 4 RepliesI am learning VB.NET and as a first task I am creating a login form. I've been trying to link it to another form once a correct username and password are entered. However, despite that I still cant be able to hide it or unload it once the next form is loaded.
Here is the Code
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
If UsernameTextBox.Text = "chris" And PasswordTextBox.Text = "chrispass" Then
Me.Hide()
Form2.Show()

Me.Close()

The Form2 appears as coded above but the 'Me.Hide()' manages to hide the login form but then it appears again.

View 1 RepliesSo just to get better at VB, I'm trying to make this application that takes pictures from your clipboard and uploads them. I'm adding a label, that will tell you if there's anything in your clipboard or not, but the problem with that is that I don't know how to make it check the clipboard all the time.I'm still a beginner, so I only know how to make the app do something when a Form has loaded up, or clicked etc., but how do I make it so it checks the clipboard when it has changed? If I can't do it, how do I make it so it checks the clipboard like maybe every second. Do I need to use threads (I'm not sure, because I don't quite fully understand threads).
