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?

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.
I have the following code:
Code:
Imports System.Data.SqlClient
Imports System.Data
Public Class Main[code]...
and the sub Exceptionquery is not working. I can verify this because it is supposed to create a new table called scratchpad3. what I may be missing in that sub routine that isn't allowing it to work?
My main form has a timer that monitors idle time in my app: no mouse movements and no clicks.If the idle time reached 3 seconds, in *this example below*, then I want to show frmRestart, which will call the UnloadAllFormsExcept(Me) function from frmMain.When three idle seconds are reached, frmRepeat starts to show on the screen but never does!! I just see the border of the form and nothing else. My mouse goes into "thinking" mode forever.[code]
View 5 RepliesFirst, I launch a website in Internet Explorer from VB.net and automatically login the user with ther username and password. As soon as the username and password fields are automated, I send "enter" to the website so it goes to the next website. This part works perfectly. However, my problem is that i want to send a mouse click event, which i have already written, to click a hyperlink on the next website page. I tried a few different things, none of which worked. My program is automatically logging in the user and doing the mouse click event at the same time. I have tried to use the "sleep" command, but the mouse click event is still not executing after the second webpage loads. I have tried using nesting "If, then" statements and that has not worked either. Does anyone know how to make sure the webpage fully loads before executing a sendkeys routine or a mouse click event? This is my code thus far:
If (Search.ComboBox1.Text = "IWR") Then
BlockInput(True)'this disables the mouse and keyboard
Dim IE As New Object
[code].....
There are no errors, everything is just executing all at once instead of letting the second webpage load and then executing the mouse click event.
Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)
View 3 RepliesSo I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..

View 1 RepliesI have a form where I have created a custom property, DataEntryRole, and set its Browsable attribute to True, as shown:
<Browsable(True)> _
Public Property DataEntryRole() As UserRole.PossibleRoles

Return mDataEntryRole

When I view the designer for my form, DataEntryRole doesn't appear in the property box. I assume that it should appear if I were to create another form that inherited from this base form, but that's not what I want. I want this property to show up in my current form.

View 9 RepliesI have a StopWatch running, I convert the milliseconds to the following format. 00:00:00 i.e HH:MM:SS which is a label.
I can pause the the stopwatch and resume but I dont seem to be able to edit the stopwatchs time. So lets say my time says 00:00:02 , i now want to pause the program which I can, but also change the stopwatch time to 00:00:10 and resume counting.

There are two location one main form and other is communication class which use comport to send command.Everything is good in VB6 but same code fails in vb.net actually program behavior is really different.in vb6 one function execute at a time but in vb.net it execute two function at a timeeg. In form there is function to write command over comport once command is posted one event is raised by serial port in this function byte array is formed and the statement immediate next to raise_event use this array to show on formbut when event is raised control is toggle between first function and event function it execute one statement from second(COMMUNICATION CLASS) function and one statement from f
View 1 RepliesI 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?
View 5 Repliesis 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.

View 3 RepliesI'm making an app using wpf and vb.net in vb2010 express and having a problem. I have a timer that execute a backgroundworker every minute:
Private Sub timer_Tick() Handles timer.Tick
If Not bworker.IsBusy Then
bworker.RunWorkerAsync()
End If
End Sub
The backgroundworker is working with xmlelement and xmldataprovider:
Private Sub bworker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bworker.DoWork
Dim source As XmlDataProvider = Application.Current.Resources("r1")
Dim sometext As String = "something"
Dim elemento As XmlElement = source.Document.CreateElement("elemento")
elemento.InnerText = sometext
e.Result = elemento
End Sub
Then I'm using e.Result on RunWorkerComplete to add the XmlElement to source. It works perfect the first time I execute the backgroundworker, but when the timer calls it the second time it throws a InvalidOperationException in the line "elemento.InnerText = sometext" why is that and how can I solve it?
