Win7 And Session 0 Isolation?
Oct 14, 2011
I 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 to handle concurrency control and I used SqlClient.SqlTransaction with IsolationLevel.Serializable level. In that transaction, I do 3 works:
1. Select the latest updated time from a record of a table
2. Compare the latest updated time with a stored time paramater
3. If the result form comparision is "same" I will update that record
But my problem is, when 2 transactions is run at almost the same time.

I have a VB.net CF app connecting to a SQL 2008 server. I'm trying to implement transactions but when i break my code at the start of a transaction certain read queries cannot be done on the table. For instance selecting all records from the table where id <> 123 Won't return any values. But select * from stock will return all values except for the row I'm working on.

I am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

Depending 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 mean not like windows xp which the number and signs are not in the same textbox, but like windows 7 which you can see the whole calculation before pressing equal, and i don't think that compute.datatable can do this because it's limited with the basic signs(+,-,/,*) and it doesn't include the other signs(like : sin,^,root,log), so how to make a calculator like windows 7 one?

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?

how to get my vb6 exe to run in any win7 or Vista?The error I'm getting is: Component comdlg32.ocx or one of it's components is not correctly registered or missing. I've tried using the P&D Wizard to specifiy loading it into the SysWOW64 folder but I'm not sure if I'm doing this correctly. I use the P&D Wizard then load everything into Inno for delivery but my customers who now have Win7 or Vista can't use my product.

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). Anyway, they only way I can resolve the issues with the modem is resarting the machine. I want to automate this. If I have problems with the modem, I want to reboot the machine and back into windows 7. How can I go about doing this? I am really concern about the login back into windows7. I want to keep the login screen up, but I want to bypass it if my program was the one to restart the machine.

I have looked through more old threads than I can count and I just cannot get any of the suggestions to work. I did a little poking around MSDN as well. I am trying to use the registry to enable AutoLogon on a Win7 machine through code. I can read the current value with no problem but I am running into security problems when I attempt to change AutoLogon to "1". This is what I have done so far.

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 have put a breakpoint in event and under Vista the events happen...under Win7 the breakpoint is never reached. In both cases I am using VB Express 2010 and running under the debugger. I have seen this problem reported before in the forums but no answer was apparent.

ETA: Using Environment.TickCount does not present the same problem. ETA2: I should add that I don't actually use the Forms.Timer in my app - as this would negate the use of a high frequency timer. I've used it here to simplify the code. ETA3: I've published a workaround as an answer below. I'm having problems with the StopWatch class that I'm observing on a laptop with XP but not a different laptop with Win7. Here's the test code:

I've created a custom DateTimePicker and implemented code I found on the web to allow customization of the BackColor of the dtp (Making use of WndProc). However, I've discovered that this doesnt work in Windows 7 with the XP Visual Styles option enabled in the project. How to make this work for Win7, without disabling the Visual Styles (the controls look ugly without them).
Below is the code I'm using:
Private _BackColorBrush As SolidBrush = New SolidBrush(SystemColors.Window)
Public Overrides Property BackColor As Color
Get
Return MyBase.BackColor
