VS 2005 Exception Freezing Program
Jul 27, 2009I have a form with binding sources and a method for saving the data.[code]I was testing to see what would happen if the operator tried entering duplicate data in the primary key field. They exception occurred as I expected but the program gets stuck at that point. The exception messagebox just keep redisplaying when you click OK. I'm fairly new to .Net, but this code is how the help files show updating a TableAdapter using the "Try/Catch".

View 4 Replies.net - Loading GIF Freezing Sometimes?
Feb 25, 2009I'm trying to use a loading overlay on top of a Windows form that adds a 50% opaque layer on top of a windows form with a loading GIF, while it does what it needs to do in a background thread. The overlay is a windows form that I'm drawing in the onPaint event.
The loading overlay works fine on multiple different form loads, but fails to work properly when summoned to ensure patience during a 30 second upload process (That Prints a Word Document to PDF, then uploads that PDF to a SQL Server). This upload collects some data from the form, puts it into an Object, then operates entirely on a background thread. The loading overlay will appear, show the first frame loading GIF, then just freeze. The onPaint is getting fired and the image frame is being updated, but it isn't visible
Constructor sets the form to be UserPainted:
Sub New()
InitializeComponent()
SetStyle(ControlStyles.UserPaint Or ControlStyles.Opaque, True)
End Sub

Forms :: While Loop Without Freezing?
Jul 30, 2011I'm a VB.Net newbie, and would like to write a small app that runs a While loop to check a DNS domain name, and exits once the domain has been registered.
I found code at How to Get Host Name and IP Address in VB.Net - .Net Articles & Samples to resolve the hostname and handle the "No such host is known" error if it still hasn't been registered, but I have a couple of issues:
1. How to make sure the GUI is correctly displayed even though there's an endless While loop? Should I use some kind of asynchronous call so that the window doesn't freeze?
2. I'd like the app to mimize to the icon bar, and have its window title display some status information ("Still waiting/Registered!") so that I can simply move the mouse over it and know whether the domain has finally been registered or not.
Forms Freezing On .show()
Mar 6, 2012I have an application that does not load a main form. My start up object is Sub Main. I am not using the application framework. I have several classes that handle different parts of the program.
objAlerts is the main one being used for this issue I am having.
This is how they are referenced in the main program class.
CODE:
This is the unfinished objAlert
CODE:
My issue is that the windows (alert.Show) open in a frozen state where the mouse pointer displays the hoursglass and the window does not respond. The windows show in the list of objects no problem.
Is there a special way that I should be opening these? I can open windows on the main class no problem.
I read that <form>.invoke(alert) might work, but there is no invoke on the main class according to VB.
I am thinking this might be a threading issue, but I don't know how to fix it because this is the first program that I have made using a Sub Main instead of a form.
IDE :: Dropdowns And Scrollbars Freezing?

View 2 RepliesIE Freezing While Accessing ActiveX?
Apr 4, 2009Lets discuss about those created active x which got created in VB6 and not working in Vista.Here i will let you know my problem,no idea wheather we need to upgrade any runtime file in VB6 or in vista?
I have done an ActiveX to get client MAC address as its major part and runs over IE.it is successfully running in Win2000, Win2003, WinXp and even with IE7 with previously mentioned Window versions.
This ActiveX was developed in VB 6.0.
This ActiveX gets installed atomatically through a cab file, whenever the application was accessed first time.
this cab file work fine in WinXP but when we try to run this cab file in vista IE get hang
Now, we have to support it with IE7 over Vista.
let me know what should I do to make it compatible with IE7 and Vista. I am using Vista Business right now.
When the application was accessed through IE7 for the first time, ActiveX installation dialog appeared. I pressed the Install button but then IE7 threw an error message that "Internet Explorer has stopped working". After that each time, whenever the application was accessed IE7 threw the same error message.
Cab file i made in VB6 using internet and deploy package wizard,along with cab file we will get one HTM file also to get Object id and code base along with version,even if we try to open this HTM file then also IE get hang.
I tested by manually registering the ocx, also turned off the Protected Mode and enabled my ActiveX through Manage Ad-on as well, but to no avail.
Infinite Loop - TCP Freezing With .NET?
Aug 12, 2009I made a game in VB .Net that uses tcp and sends messages back and forth.What is happening is, every so often, the message cannot be sent quickly enough, so then the TCPObj.connect() method goes into a loop, until it reaches the timeout and then spits out an error. Most of the time though, it never gets to the error, my application just freezes, and then comes back after TCPObj.connect() succeeds. How can I make the connect() method do application.doevents while it's trying to connect? Basically, I dont want it to freeze up my whole application. Since tcp.connect() is a .NET method, I can't go in and add application.doevents.
View 3 RepliesPause Without Freezing The Application
Dec 23, 2011I have a loop and within that loop I'm running a Dispatcher Timer.[code]Basically what I want is to show each item in the items list pausing after each on for 5 seconds. I want to show elapsed time in a label and after the elapsed time hits 5 seconds show the next item. This is not possible using the Thred.Sleep method, because it just freezes my application for 5 seconds, and shows the next item without ever updating the label with elapsed time.So what to use instead of Thread.Sleep to not freeze the application and update the label with elapsed time?

ActiveX Blocking Functions Freezing The UI
Aug 27, 2010Is there a way to include an ActiveX to VB .NET project without adding it to a form?
If I add it to the form and call a function on it that blocks, the UI is unresponsive until the function returns. Even if I am making the call in a different thread.
I was able to compile the code when I did not include it via the form, but got this error once I called a function on it.
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
How could I make the UI responsive when the ActiveX functions are blocking?
Add Background Workers To Prevent Freezing
Oct 3, 2011I am a bit of a noobie with vb.net and I made this application that does a lot of http requests and stream reading. But when it does this it always freezes my application.So I did a little research and found that I could use background workers to solve this. But I have no idea where to start. So if you could look at my code and tell me where and how I can add background workers to prevent the freezing that would be awesome.[code]
View 2 RepliesCommunications :: TCP Request Freezing Application
Nov 4, 2008I have a Data Acquisition and Control application that controls at 10 Hz and logs at 1 Hz. Both of those timers call a separate. I recently added a feature to the program to request 6 characters from a server for the barometric pressure. (29.206, etc) It works for the most part, but two weeks ago a computer froze, last week another one froze, and two froze this morning. I have not had freezing problems in the nearly three years this program has been running 24/7. Turns out they disconnected the server this morning, so that explains the simultaneous freezes in two test cells. I used a try catch statement, but apparently that wasn't good enough. how I can make this code more robust?
