VS 2008 Form Hangs Under Vista 64 Bits?
Jul 8, 2010
I have detected a problem running my application under Vista 64 bits OS.
My application is developed using VB.NT 2008 and compiled as x86
I have a main form. In this form there is an option to open other form. TThis second form must return a few values to the main form. When the user click on this 2nd form, to return values, this form hangs up (2nd form hangs up)
But for what I could have known, it continues executing the rest of code that exists after to open form. I want to say that the form dialog (2nd form) is not closed (hangs up) but it the code continues being executed, because I have seen that inserts the data in the database.
The application not returns any error and any exception.
frmWaiting (form displayed when call thread)
This forms contains progressbar
main form
Dim ThreadVentas As System.Threading.Thread

I have a heavily timer tick driven application that seems to randomly just stop on vista/w7 while minimized, sometimes it goes on for hours sometimes just minutes but the end result is same just stops for no apparent reason, the moment i unminimize it it keeps going. This never happens on xp tho where it works perfectly so what might be the problem?

I have an installer class that presents a form to the user. One of the functions of the form is to browse to a file using the open file dialog. This form functions fine when used in an application but hangs when calling OpenFileDialog.ShowDialog() during an installation on a Windows7 or Vista machine (Windows XP it works as expected). I get the same rusult when 'run as administrator' and with UAC off. I also get the same results when calling SaveFileDialog.ShowDialog() in the same context. The call doesn't throw an exception but causes the form to stop responding. Any suggestions on how to get this to work correctly?

The VB2K8 Express IDE is hanging intermittantly when I click on the form's Design tab. The tab's work area goes blank and a wait cursor appears. I can't switch tabs or do anything else within the IDE at this point. I have to go to the Task Manager, end the VB taskk, and restart the IDE. VB is at SP 1 with .NET 3.5. I have no third party add-ins or controls except for the Visual Basic Power Packs which aren't being used. At this point it is annoying and I haven't lost anything yet but it is happening more frequently over time.

I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.

I'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.

I have win7 pro, on my win form is a traffic light icon(when it starts it is red, when finished it is green), so that I know when job is finished. But when I run application icon isn't changing and form hangs it self, can not do nothing until job is finished. Only in the end, I see that icon is quickly changes to red and then back to green.

For my VB.NET application, I'm using the windows installer that came with Visual Studio. I can successfully install and run my program on any computer in our office except for one. On this particular machine, my program will stall for about 30 seconds before being able to load the main form. When I start up the task manager, the CPU is hovering at about 0 to 1%, so its not really doing anything but freezing up. It will eventually load, but it really shouldnt take this long, especially when it loads instantly on other computers. Now this machine is windows xp with serverice pack 3 and .net 3.5 sp1.

This seems like it would be so simple and fast, but I cannot figure out how to accomplish it in VB since there aren't many bit functions. I want to take a file and append 5 junk bits at the beginning and 3 junk bits at the end. In essence, just add 1 byte to the file, but in the process offset all the current bits so the file is no longer readable.
I just need a very simple encryption/decryption, but it needs to be very fast as well. I try XORing the bytes, but it gets slow with just a 1MB file. Some of the files are going to be close to 10MB.

I have written a simple VB.net application which saves information to an RFID tag. I am now trying to compress my data. The solution I have come up with involves bitwire operation.Basically I store 2 numbers per 1 byte (0-9, 10 being a period, 12 possibly being a negative/positive flag,13,14,15 unused as of yet).The code I am using basically shifts the byte containing a number left, 4 spaces, then 'OR's it against another number.Therefore 12 is now represented as 00010010. The problem i'm having is decompressing. Obviously getting the '1' back is easy, as I just shift right 4, then grab it. I need to append or remove the last 4 bits.My solution after many headaches was to reverse the bit order, shift left 4, then reverse, then tostring it.

I am writing my first application in Visual Basic Express 2008 and the program conistently hangs (Not responding in the Task Manager) midway through execution. The operating system is Windows XP Professional SP3 running on a 1.20 GHz Intel Core Duo CPU with 2 GB of RAM.
The application has very deep layers of subroutines and functions, all of which are using lots of math routines. There are no recursive routines anywhere in the program. The program creates and destroys quite a few class elements, and I have written dispose methods for all of them using IDisposable, setting all the properties to Nothing. I also use GC.Collect() to force garbide collection, and GC.WaitForPendingFinalizers(). As a result, I don't think there are any memory leaks.
I think the depth of sub and function calls are causing a stack overflow, but I'm not certain. I have tried without success to increase the stack allocation to 2 Mb using Editbin.exe after reading some forums, but nothing changed. I then searched my machine and did not find EDITBIN.EXE.When the program hangs up, the background of the forms on the screen turn to solid white and the controls are no longer visible.It looks like a window pops up but it disappears too quickly to read anything. If I view the task manager while the application is running it hangs immediately. I have not published it, I am still developing and running it out of the VB environment.The more complexity (sub and function calls) I add, the earlier the program hangs.

For some reason, the Add New Item command on the Project Menu is hanging VB on my Vista based machine.but now, it hangs. By that I mean the the little circle cursor spins and spins and spins... This happens even when all I do is start VB, start and new project. and then try to add something, eg. another form, a class, anything except "existing item".

I'm using Vista Ultimate x64 to develop on and I have found that any unhandled exceptions that I would expect to get thrown in the Load event of a form do not actually get thrown... This happens no matter which compile mode I select (x86, x64 or AnyCPU). If I copy the exact same EXE to an XP machine then the unhandled exception is thrown as expected and the JIT debugger warning message appears. Its very annoying as absolutely no indication that an exception has occurred is shown, the program just loads normally but anything after where the exception should have been thrown is not executed. For example, if I create a new project now and stick this in the form load event then the program would just load as if nothing has gone wrong:
My.Computer.FileSystem.ReadAllText("----")

windows service app I am developing to audit events in the Windows Security Event Log. I am using the EventLog class to read entries from the "Security" event log. I have set the log to raise events when an entry is written so I can parse the data. Here is where my problem comes in. If I run the service on Windows 2003 I can get all the data I need from each entry, but when installed on Server 2008 the EventLogEntry ".message" property comes back with useless data like this, "The description for Event ID '4738' in Source 'Microsoft-Windows-Security-Auditing' cannot be found." Under Server 2003 the message property has good data. Using the Event Log Viewer in Server 2008 I can see that it is rendering the correct data, but I am having a heak of a time doing the same. The "replacementStrings" property has the corresponding data that I need, but it appears to involve some other steps to get the data localized to the event provider, but I do not know how to do that.
I also checked the registry HKLMSystemCurrentControlSetServicesEventlogSecuritySecurity on both the 2003 servers and 2008 servers. They are identical execpt the 2003 has an entry the 2008 server does not:
String Type: GuidMessageFile

Editing a Visual Studio 2008 solution (1 Windows project and 1 installer project) that has been working flawlessly.Recently, attempts to edit the Dataset (add/modify queries) by right-clicking the dataset and selecting "Edit Dataset With Designer" brings up the MyProject_Dataset.xsd window TAB, and initially displays "Please wait while loading..." in the middle of the window -- and then does nothing else.Alt-Tabbing to other apps then leaves "ghost window" stuff displayed where "Please wait while loading" once was... and editing queries, etc., is impossible.Shutting down Visual Studio will enable me to successfully get into the editor once ot twice, but then it locks up again.
