Showing of my forms is somewhat slow, I am thinking of loading them when the app is started but I am worried it will take too much memory. What other means can I do to make the showing of the form faster?

I have a Setup form that calls the main form after the user clicks on a button. This works fine in VB6, but in VB.Net, the original form either hangs around if I call the new form with .ShowDialog() or the new form exits immediately if I call the new form with .Show()...
View 1 RepliesI have a menu which when clicked will load form which take quite sometimes (although not very long) but the user keeps on clicking the menu and so the "not responding" message appears on the title bar of the app. I am thinking of displaying "Loading....Please Wait" so that users will stop clicking the menu or will wait until the loading of the form is completed. I tried these code but the form is still displayed even if form has loaded completely. [Code] I like to use the same concept also when the user clicked the save button, to tell the user to wait while changes are being saved.

I'm developing a windows application using vb.net (VS 2005 and windows XP) I've set images (transparent png files) to buttons.I do it importing images into the resources of the project I could do it for most of the buttons of this project, but today I noticed new images I set, not showing in run time. In the development form I can see all images on buttons, but when I run the application, buttons with new images are missing. This happens to the new images I import and set as button images. I tried few times new images I set are not showing.
View 18 RepliesI fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

I open a form using .showdialog and load some info onto it. I have code that runs on the MyBase.Load event. Basically, I have a Try, Catch, End Try block and if the Catch executes in preparing my information, I want the form to stop loading i.e. give a message and not show at all.

I have created a series of custom user controls for a wizard interface that I am making. Each user control represents one step in the wizard and really shouldn't be used outside of the wizard. The thing that is bugging me is that each wizard step user control shows up in the toolbox of components to insert into a form.
Is it possible to hide a user control from the toolbox? Better yet is it possible to hide a user control from other classes not in the same namespace of an assembly? Is this a good approach or should I think of a different approach?
Why is my MDIChild form not being displayed in my MDIParent form? I want to click a button on form frmStudyResultsFilter which will then display an MDIContainer form frmCalculatedResults (maximized). When frmCalculatedResults is shown I want a small dialog modal form to be in the center of frmCalculatedResults. For some reason frmCalculatedResults will not show on top. Plus I get this error"Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling ShowDialog." Here is my code:
Public Class frmStudyResultsFilter
Private Sub btnCalculated_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculated.Click

I'm sure I'm doing my login process for my app in a not so perfect way, but as with lots of things, it works. The issue is to make it work I have to use the very unpopular DoEvents thing. I would like my application to show a login screen before loading my main form. Currently I have a login dialog box with a FormOpen boolean property and an authenticated boolean property. If a user logs in successfully, I hide the login form, set formopen to false, and authenticated to true. If they cancel out, then I do the same and just set the authenticated property to false. If authenticated=false then I end the app, else I show the main form via application.run(MainForm)

View 3 RepliesI'm trying to figure out how to set the form's location/size before calling the .show method. I figured out the location part, but still can't figure out the size part. No matter what size I set the form to in the designer, it never uses that, so I figured I would set it with code right after setting the location.
'set location before .show
Form2.StartPosition = FormStartPosition.Manual
Form2.Location = New Point(103, 449)

In a Winform application, I'd like to animate the showing of a form a bit like when an email comes in and the notification window raises slowly from the bottom of the task bar.
I've got a few ideas involving timers and resize but they all seem complicated and/or clumsy so I wonder if anybody could suggest a simple way to do this or some magic function I could use to do it automatically.

When textbox1.focus() at that time i clicked Control + Enter key, the formid=55 is showing instead of formid=54.
I have a single form called 'FolderSelector' with a label, textbox and a button.The problem I'm having is that everytime I run the application, the only thing that shows up is a blank form called 'Form1', the program runs everything it should do except to show the actual form which is really weird.Here's the code in case there's something in there that's causing it that I haven't spotted.
Imports System.IO.Directory
Public Class FolderSelector
Public Const SPI_SETDESKWALLPAPER As Integer = &H14
Public Const SPIF_UPDATEINIFILE As Integer = &H1

I wrote an application with multiple forms.One form is used to show any kind of messages helpful to the user (frmMessageWindow).The user has the option to not show frmMessage Window.I would like to hide frmMessageWindowbut keep it loaded and continue to add messages to it so they will be available when the user chooses to show the form again.I use frm MessageWindow.Visible = false to hide the form and this works fine.But there is a check box on frmMessageWindow and if I check the value from another form it makes frmMessageWindow visible.
View 2 RepliesSomething annoying suddenly happened with a text box in a self made program in Visual basic 2008. Whenever I try to run the program, this text box shows what is behind the program itself. (For example my desktop background)
Not only that, if I click on it with the mouse, the window which is behind my application will pop up in front.
I tried to replace it with a new text box and a new name, in case I'd been messing around with some wrong properties, but the problem still remained.
I don't know why but text that should display in a text box, ALSO appears at the top of the form, where the title would be. Here are pictures of what I mean. The first picture is before the button to display the text is clicked. The title at the top is "Surrogates (20009)". The second picture is after the button is clicked and as you can see the text shows up in both the textbox and at the top.
