I am making an application that asks a series of multiple choice questions. I have created an array of forms for my questions and I want to open one at a time, once the question is answered, that form closes and the next one in the array is opened. What i want to know is how to open just one at a time, i have a loop that opens the forms, but instead of one at a time, it opens the forms all at once. here is my code.

I added 2 textboxes on the form and runs it...I pressed the enter after I type in simple text.. it will not goto next textbox but tab can do.

What's the best way to save the form state & reload when the program next runs.
I mean text he has entered in list boxes, the selected item of combo/list/radio, whether a checkbox is cheeked, etc
I've created a form with a PictureBox on it and would like to dynamically create another PictureBox on the form while the program runs (to the left of the static one). I've written this code:
Dim temp As PictureBox
temp = New PictureBox
temp.Image = StaticPictureBox.Image
temp.Visible = True
[code]....
When I run this code I can detect that the temp PictureBox does get created. However, it is not rendered onto the form. It seems like it's there but is invisible.
Im Using VB 2008. I have MsgBox() statements in all Mouse & Form Click events to TEST & NOTHING FIRES during Form Load when I click on Form or Button Controls !!! The Form Load event contains code for Displaying the Label.Text control many times with changes in the Text to simmulate annimation.

The following code does create a form within a form and does place NotePad inside the child form. You have to manually start NotePad prior to execution (I work on that later) but the code does workŠ My problem is now I want to manipulate the properties of notepad i.e. focus, size, location, etc. but I cannot figure out how to reference notepad and its properties.

I have a form being called form several forms using ShowDialog().
1. Is there a way for called form to know which form called it by receiving a code or key from the calling form?
2. The calling form has a gridview. How can the called form pick up a column's value from the currently highlighted row in gridview in the calling form?
i have my main child form open. then i show the new form:
[Code]...
but when the form opens it flickers a lot. so i want move the new form behind the main form while it loads so the user does not see the flicker. once it is done loading i will set the form to topmost. how do i move the new form behind the main form?
I have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.
What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.
I designed a class contains a form that have buttons. When i click any button this function runs
Public Sub BtnClick(ByVal sender As Object, ByVal e As EventArgs)
result = CType(sender, Button).Text

In another project I imported this class. I called the method that shows the form in my class. I need to store the 'result' variable in another variable in the new project. How can It be done.
how to pass value from one form into another form...? for example if i have 1 mdiform and 2 form (form1, and form2) for load form1 i'm using system.reflection.assembly here is the code for load form1 :
Imports System.Reflection
Private Asm As Assembly
Private FrmNama As Form
Public Function GetForm(ByVal FormName As String) As Form
[code]....
after form1 load i call form2 from form1 and from form2 i want pass value, here is the code from form2 to pass value into form1 :
form1.textbox1.text = textform2.text
why value from form2 can't fill into textbox1 in form1?
I'm new in .Net and I have an application with windows form "LOGIN" When users enter the user and password and click "ok", then if user passes validation then I have the code Show(MDIMainMenu) (I'm trying to open an mdi form), but I receive the following error: "Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling Show. Error Number 5"

i want to be able to click anywhere there isn't a control on the form and be able to move the form to anywhere on the desktop...
the control box is off and the form text is blank, so there is nowhere on top of the form to click and move the form..
I wish to get my VB 2010 program to wait a few seconds after executing a command, and then exit.
For example:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'do.stuff
'wait a few seconds

View 6 RepliesI am writing a very basic memory match card game, and am trying to get the program to flip over the selected cards, wait 2 seconds so the user can see the values, then flip back over. The code I have to do this is:

I know there is always better ways of doing things. Normally when you create a thread and I want it to pause/sleep for a set amount of time I use the <Object>.Sleep(1000) but this is frowned upon in .Net2+.

using Timer in this code as it doesn't seems to work.[code]

Dim returnTime As Date = Now.AddSeconds(seconds)

okay this may be a simple answer so I apologize if it is. What I'm trying to do is when button1 is clicked for a text box to display text. Then when that same button is clicked again, that text box will display different text. Then so fourth for about another 4 times. Now I know putting this all together will create one big execution, which I don't want. I just want the application to wait until the button is clicked again to display different text.

I have a VB Windows App created using VS2K10. It produces pdf files from SQL data. The SQL data is refreshed every 10 minutes pulling from a DB2 (ERP) system via a Linked Server by a SQL DTS package being run by SQL Job Agent (SQL 2005). Because of OLEDB and security issues, the data download can only be performed by a specific Windows 2003 server. (It takes from 2-3.5 minutes to download the necessary data.)
Now, if the process of creating and printing the PDF files takes longer than 6 minutes then it's still running while the next data download is starting, the result of which is that several PDF files are created blank or absent any data. I tried to execute the DTS package on demand instead of on a timer, but cannot get past the OLEDB quirks related to our iSeries (IBM server) DB2 database system. The only answer seems to be to have the client application pause at a specific time interval and resume after @ 4 minutes, but I haven't a clue as to how to do that. Before you ask, using ODBC to pull specific data from the DB2 system directly into the client is too slow to be a viable option.
I have a problem with my application "getting ahead of itself" what the problem stems from is i am manipulating a file and then using the manipulated file further along in the program, the trouble is the program is getting to the second step before the file manipulation is complete so i receive a file not found exception. The program that is doing the manipulation has an OnEnd sub routine and i have been looking at event handlers to try and figure out how i can hold up the application until the On End routine is fired. But i have been trying this to no avail, is there an example i can have that waits for an event to be fired?
View 17 RepliesI'm trying to play a MIDI file in my VB.NET (VB 2010 Express) and things work well with the code from this other question here on Stack Overflow, which I translated from C to VB.However, I also need to PAUSE, while that code is only for open and stop. I edited the code like this:

I would like some information on pausing my application until a file with a certain extension has been created. What hapens is, my application creates an input file that is sent to an external app that returns a file with a different file extension. In my application i then extract data from this new file.I was thinking i could use a timer to "hold up" my app, but then i started reading about event handlers and catchers. What i have tried is using an If FileExists loop but i get a file not found exception. How should i use the file create event? By looking in the folder and "waiting" for the file to be created?
View 6 RepliesIs there a way to play a wav file and then pause for 10 seconds and then it will repeat? I know it will be a loop, but the part that gets me is pausing for 10 seconds before starting the loop again.
View 1 RepliesI'm making... well, it's sort of like a game in VB.net (using VS2008, if it matters). Being sort of like a game, it's dependent on timing, but it also has a large area (have to scroll the window on pretty much any resolution).The problem I'm having is that whenever I scroll the window (or move any of the smaller, additional windows) the program pauses what it's doing, and doesn't start again until I stop scrolling (or moving windows, or whatever).So is there any way to stop it pausing when you scroll or move windows?
View 1 Repliesi am trying to understand how to keep my console app open even after it gathers data and sends it off. I am converting a GUI to the console app. It has a timer that fires the sub every 20 seconds. But it doesnt seem like it works in the console app since after it fires off the sub it closes the app without waiting.
