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 made an application to give to my friends as practice for my learning, so the app works fine with XP but not on a Vista 64 bit machine. Will the app need re-coding? The app is used as a game mod, so it writes to process.
View 2 RepliesWe have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?

We have a VBA based application that run with Excel, in where we are facing an error like "COMPILE ERROR IN HIDDEN MODULE". This issue occurs only at WINDOWS VISTA machine. This issue does not occur with WindowsXP/Windows 2000
Initially this issue comes where ever "Dictionary" class used. When we replaced it by explicitly specifying it's library like "Scripting.Dictionary", the same error comes where ever "VBA" library classes used. After investigating further, it's found that none of the built in classes able to find references to their corresponding libraries. We have all the proper references check box checked, at Menu-> Tools-> References Window.

I was having trouble before editing the registry on a WPF application I'm working on, in order to get autostart to work, so I ended up creating a shortcut in the startup folder to automatically start the application. My problem is, that this not working on Windows 7 (and Im guessing Vista too). Here's my code. Does Environment.SpecialFolder.Startup not work on Windows 7?

how to get working aero in Visual Basic 2008.I am making this media player and got everything I need for that. But what I really wanted is aero since Windows Vista got a nice interface and a few lucky people got it.But the tutorials I got worked great on Windows 7! However, I couldn't get aero because of a transparency key. (I swear I use a color picker to see if background color and transparency key are the same color.)I can't get it to work any piece of code I give.But the good part is that aero WILL work on any 7 or Vista without any form change, but the text is white with blue specks and that is not what I want.
EDIT:i found how to do it now! you need to use the property UseCompatibleTextRendring and put it to True. Now the problem is how do i do the same for the rest? (microsoft was to lazy to edit the controls)
I have an app developed in VB that works fine on Vista machines but fails on Win7. The offending line of code merely references a variable stored in a module. Evidentally, something is quite different on Win7. How to I find and fix this behavior?
The code is very straightforward. The error occurs in the Application Startup event.

ByVal e As ApplicationServices.StartupEventArgs) _

my goal is to control the incoming and outgoing packets to a game server, to alert when a game round finishes the main code is this:
Private Buffer(65535) As Byte
Private RawSocket As Socket

this code works perfectly with XP (you can read both incoming and outgoing packets to the game server)... with Vista the same code displays ONLY the incoming packets....
Ok, I'm trying to tackle this topic again. I have searched for setting file associations in the registry, and I only find references to adding the association the ClassesRoot, which, in Vista 64, throws an Access Denied exception.I would like to know if it is possible to set the association somewhere other than classesroot in the registry. Or, if it must be set in HKCR, then the proper way to temporarily elevate the application to perform the registry change.
What should happen is user clicks a button in my program to add the file associations, a Vista security dialog pops up prompting the user to confirm the operation or enter administrative username and password, user confirms, application sets the file associations, then drops back down to regular security.
in vista, if we fires a dialog box then the background get dimmed.

The reason I am starting a new thread is to be more concise; explain the exact issue I now face in detail. Reading my last thread may help, but what I provide here should be sufficient. I am basically trying to find the best route I should take for my program as far as UAC and Vista is concerned. My program (SysPad) is accessible through my sig).
My program requires constant write access. The purpose of my program is to provide access to a quick notepad-esque program that is directly accessible from the Notification Area. It saves every time the user types into one of the textboxes.
The issue lies in the fact that when UAC is enabled on Vista, there is no folder that is writable to without elevation to Administrator rights. The hitch is that my program is designed to be a startup utility and the issue is that a user who has UAC enabled will have to allow my program through UAC confirmation every time my program runs at startup.
Basically, I am looking for options that will resolve this and make it less "painful" on the end user who uses UAC.
Basically, the only idea I've been able to come up with that is least annoying/intrusive, is to create a Launcher.exe program that does not require elevation and have it sitting in the Notification Area with the same icon as my program at startup. When the user goes to access the program, it then launches the actual program (exiting the launcher) thus invoking the UAC verification.
Of course this would happen every time they boot their PC or restart my program; but, at least they won't be asked for UAC verification as soon as their PC boots.
Does anyone have any other suggestions? I really would like to get this to work with UAC as best as possible. Otherwise, I could just make my program check if UAC is enabled, and if it is, tell them they can't use my program lol. But, I'd rather not do that.

i've been looking for a solutions/alternatives to use sendkeys in Vista after reading many threads about the issue, i did see posts of alternatives, there was mentioning that SendKeys does work in Vista with .Net v3.x Framwork.

I tried running this application as administrator, even though I am on an admin account. I even disabled UAC. Nothing seems to work.

I've encountered several scenarios when my application wants to delete an item, but is prevented from doing so by the operating system. So I've been wondering, is it possible to ask for elevated status after the application has launched? E.g. the application needs to delete a certain file, so it asks for confirmation and then deletes the file...
