Stop Forms From Freezing?
Aug 21, 2010Is there a way to stop or minimize forms and dialogue boxes from freezing? they seem to take up a lot of memory when loading to the point that they some times look transparent for a few seconds.

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.
Forms - Binary File Read Operation - Make Searches Fast Without Freezing The UI
Feb 9, 2011I have a windows form which to summarize lets the user open a file containing 32 bit hashes, then search for one of them. The hash is then converted to its string representation. The application is giving the results I would expect but I'd like to make it execute faster than it does now; some files can be pretty big > 100 MB.
I'm doing the file read using a BackgroundWorker object to display progress updates and ensure that the UI is available during the process. But for that i need to add a System.Threading.Sleep(1) instruction in the loop; otherwise the application freezes with big files. And System.Threading.Sleep(1) creates a noticeable lag. Any suggestions on how to make searches fast without freezing the UI? Getting speeds comparable to hex editor programs for example.

View 1 RepliesForms :: Stop Loop With Button Control?
Dec 5, 2010I am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.
View 2 RepliesForms :: Trying To Coordinate Start And Stop Buttons
May 21, 2009I'm very new to Visual Basic, and have just installed VB Express 2008 from a Sams book titled, "Teach Yourself Visual Basic 2008 in 24 Hours", by James Foxall. I've managed to make it through most of the book, which was very helpful in getting a quick jump start, but I find that I am still "not quite getting it" yet.
I've written a program that has a "Start" and "Stop" button which are suppose to control the logging of data through a serial port. When I click the Start button, the serial port gets initialized, opened, and then I go into a Do-Loop-Until loop to process the incoming data stream, and that is suppose to stop when the Stop button is pressed. However, I haven't figured out how to implement that.

View 1 RepliesC# - Stop Developers From Calling System.Windows.Forms.Application.DoEvents()?
Mar 15, 2009We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:
Add checkin gates to source control?
Developer training?
Code Analysis rules (why is this not already a built-in rule?)

View 6 RepliesStopping Multiple Timers - Stop Button To Stop Each Timer One At A Time
Feb 26, 2009Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

View 5 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

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?
