I have a winform, VBExpress 2008 with a single button and this code behind it to illustrate the problem:

MsgBox(OpenFileDialog1.FileName)

I have a winform, VBExpress 2008 with a single button and this code behind it to illustrate the problem:
CODE:
When I select a file (in my case small PDF's) I am getting a 3 to 6 second delay after selecting the file until it goes on to the next statement, in this case a MsgBox.
If I repeat selecting that same file a second time, I don't get the delay. But, if I exit the program and re-start it, then I do get the delay again (one time). After the first one hangs it looks like it hangs about ever 7 to 9 tries and the window says "not responding" for a few seconds. I don't have this problem on Vista or XP.
If I select the same file over and over, it might hang the 1st, 2nd and 12th time. Close program try same again, this might be the 1st, 3rd and 9th time. Never the same - as if it is running out of resources and clearing a cache.
I've watched the task manager during the delay and don't see anything unusual coming up. I have a new computer with everything operating properly. I thought maybe it was my Norton Internet Security -- but I turned that off and it made no difference.
How I might trace the source of the delay to the bottom of it? I've tried everything I know to isolate the problem and am running out of ideas. I don't see any other posts about this particular thing.
I know the propertys transparency key and opacity. It isnt what I am looking for. I need to have my form to have the same Glass Effect the as win7 does while runing under win7 plataform. Like, if i have glass effect in the top I should have it in the background.
View 14 RepliesI know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

View 1 RepliesDepending on what component is handling the print for you, some of them are not 64 bit ready (i.e. 32 bit only). To use them you must compile your application as 32 bit only. It will then run on the WOW platform that Win7 supplies.
You change this option on the PropertiesCompile screen. Press Advanced Compile Options and review Target CPU:

I used VB6 to create an EXE file that uses MSComm1.The program runs OK in my XP computer and also in my Win7 computer (that has VBE installed).It would not run on my Vista laptop. I installed the VB runtime files (even though Microsoft says they are not compatible with Vista/Win7) but with no success.However, when I installed VBE on the laptop, it now runs the EXE quite happily.Does installing VBE also install a different set of runtime files?Is it posible to distribute my program to my friends who have Vista or Win 7, without them having to first install VBE?

View 1 RepliesI am making a windows service that will communicate with a local application through named pipes, and with a server through WCF webservice. So the application hosts the WCF service for the local application, and is a client for the webservices. When trying to run this as a service, the whole thing crashes. I have localized the problem to the "Session 0 Isolation" issue?
�If two-way interaction is required, use Windows Communication Foundation (WCF), .NET remoting, named pipes, or any other interprocess communication (IPC) mechanism (excluding window messages) to communicate across sessions. WCF and Remoting have a better security enforcement that will prompt the user (assuming UAC not shut-off) to elevate if needed. But I am not sure what they meen. As far as I know, i cannot create a windows service as WCF.
I have a vb.net program that is using a voice modem. Well, there is a someweird issues with the modem. (I am trying to work with them but they are kinda slow).

I have a program for playing MP3 files using Media Player. The program developed originally under Vista using VBExpress 2010 works fine.
But when I run it under Win7 parts of the program don't work. In both cases the audio is played OK but under Win7 the 'playstatechange' events don't seem to happen!?!

I've had developing an old vb6 (sp6) app in my pc with winxp and running it in other with win7.
View 1 RepliesHere's a drilled-down version of what I'm trying to do.
Module Module1
Sub Main()
Dim regType As Microsoft.Win32.RegistryValueKind = Microsoft.Win32.RegistryValueKind.String
Dim regKey As String = "SOFTWAREFOOBAR"
[code]....
On Windows XP, this works fine. On my Windows 7 64 machine, if I simply run the executable normally, it throws an exception - something along the lines that access to HKCUSOFTWAREFOOBAR is denied. I'm typing this from my XP machine so I don't have the exact message at the moment, but that is the gist of it.
Now, if I run the executable in administrator mode, then it works fine. The intuitive explanation is that writing to HKCU requires elevated privileges. But I've run Steam on the Win7 machine, and I'm pretty sure Steam writes to HKCU without needing elevated privileges. Just running it while logged in as an admin is enough. So, is it possible for me to write a program that creates keys in HKCU too, without needing the user to manually invoke admin mode?
I'm trying to make a utility that will fade out the system volume (for when I fall asleep listening to my music). In XP and prior, controlling the system audio was very simple, however, in Vista and 7, I can't figure out how to do it. Because in Windows 7 each application has it's own volume control, lowering the volume doesn't affect the system overall - only the current app. Can anyone point me to a resource how to do this? Every forum posting that I've found on this topic is about XP, and doesn't work under newer versions of Windows.
