VS 2008 - Form To Show That The Program Is Busy Thus The "ShareClass.LoadingIndicator" Routine
Aug 21, 2009
Look at the first section of code below:
Private Sub vIV_Comp_Cert_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles vIV_Comp_Cert.Enter
CurrForm = sender
[CODE]...
This code is used to load a PDF in a PDF viewer. Because the PDFs are sometimes huge and there is no idea on how fast the machines are that will access the app, I have created a form to show that the program is busy thus the "ShareClass.LoadingIndicator" routine.
Here is the ShareClass.LoadingIndicator Routine:
Shared Sub LoadingIndicator()
Dim frm As New LoadingIndicator
frm.TransparencyKey = Color.Magenta
[CODE]...
The problem I have is that when the app runs and these subs fire, the LoadingIndicator form shows up but the ProgressBar1 and Label1 show as all black on the screen. I tried to make a screen shot of this but the screen shot showed nothing as if the form wasn't even there. How can I resolve this? What I would like to do is make the LoadingIndicator form be borderless so it appears as a label and progressbar laid ontop of the loading PDF reader as the PDF loads. If I take the transparency off it works fine.

Is there a command in vb that can be used to pause a routine to give time for the form to show before the routine starts as my routine is running and completing before my form shows up?

I am currently working on a launcher, and it must consist of the following:
- one main routine being called, NO WINDOW may be created at any times after or before this main routine.
- one small form called by the main routine if a certain command was sent through the Command (shortcut).
At this point I use a Windows Form, but it seems a little useless to create and initialize a form if you won't even use it. Any way to make a routine run when my program starts without showing any window? But still make it possible to show that small dialog?
I did this at first but it seems a bit dangerous:
'NOTE: The following procedure is required by the Windows Form Designer 'It can be modified using the Windows Form Designer. 'Do not modify it using the code editor.
<System.Diagnostics.DebuggerStepThrough()> _
Private Sub InitializeComponent()
Main()
End Sub
Sub Main()
'Code to run here
End Sub
It starts another program (process) which has a GUI, so I do not want to display a console window.

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?

is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5
[Routine A]
Else
[Routine B]
End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.

I have a small program which draws some lines with a method called: Drawlines But Now I want to call this method in the load form routine. So if the form is loaded the lines should be drawn in the picturebox. But is this possible or should the form first be loaded completely before you can call methods in that same form?

I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.
Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"
[Code]....
The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.

Can a data grid in another open form be refreshed by calling a sub routine? This app has a form with 2 data grids. When the user double click on one of the grids another form is opened that shows data details. After the user changes the details the user clicks a save button. We have placed this code in the Closing event of the the details form.
Private Sub FormParents_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
FormParentsAndStudents.RefreshDataGrids()
End Sub
[Code]...
Can you tell us what additional coding is needed to refresh this data or if we are using the incorrect place to call this code from within the details form?

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.

My mate & Myself are currently building a IRC Client, a problem we have come across is when opening a chatroom the form Freezes for example.
We are currently using arrays so we can open multiple chat rooms and at this current time to open a chat room we use
Channels(ChatIndex).Show()
The form opens but freezes.
I have also tried using
Channels(ChatIndex).ShowDialog()
Application.DoEvents()
Using the above code, the form does not freeze but appears we can not access any of the controls such as (RTB)
What would be causing the form to freeze on .show(), Has anyone else had any similar issues?
