View 4 RepliesNot really asking for code, but I'm interested in knowing the basics of "thread performance".For example, you try to copy a bitmap in a pixel by pixel operation. (Is slow, but it is a nice example)
[code]...
This is, of course, very buggy and causes a lot of violation errors etc. But that doesn't matter right now. How come the multi-threading way is so much faster than the regular routine? Is the processor not running on full speed with the first code, and is it working harder on the second?I find it weird to see this type of "threading performance increase", as if every single thread gets their own piece of processor speed allocated like it is a new process
I have the following windows service file:
Imports System.ServiceProcess
Imports System.IO
Public Class fswService
[Code].....
2 problems: first, intellisense error saying: 'fswService' is a type and cannot be used as an expression. second, I can not figure out a way to pass on to the service the path of the folder to watch (which is stored at My.Settings.userPath).
Is there a way I can use VS 2008 to monitor a Windows Server 2008 (R2) that I do not have admin rights to? We run a SQL Server 2008 installation on it, and I am concerned there may be issues with the OS but no one from our ISIT Support group seems able to find any problems. I've asked for remote desktop connectivity but keep being denied, and so I'm trying to find a work around. I'm OK with VS 2005 and have not used VS 2008, but figured 2008 would have the most current functionality. Basically I would like to build a Windows Performance Monitor to connect to the server from my desktop.
View 4 RepliesI have a windows service written in .net framework 2.0. This service installs and runs perfectly fine on both XP and windows server 2003.We have a new 2008 box that we are migrating over to, so need to get this windows service up and running.When i try to 'start' the windows service on the 2008 machine, i get "Windows could not start the <service> service on local computer. Error 1053: The service did not respond to the start or control request in a timely fashion."I have searched everywhere looking for an answer, and all I could find was a fix attributed to .net framework 1.1 for this same error. That; however, is not applicable here, as the service was written in 2.0.

View 4 RepliesI am trying to create a windows service that sits in the background waiting for programs to be started. When the programs start I want to be able to check a unique bit of information for each program (I believe GUIDs may provide this) to see what the program is. If the program is not allowed, I aim to provide a warning to the user and possibly close the program. The aim of the application is to identify when users are attempting to install additional software on to the computer so simply monitoring for a certain executable wouldn't work as msiexec is called for all MSI's and as I only want to stop blacklisted programs...this wouldn't work.
View 4 RepliesI have a dual monitor setup. I want my app to run in the secondary monitor by default (through settings in my app). I have been browsing the net for a solution and I found a solution which is setting the Form.Bounds to the Bounds of the secondary monitor. My problem is that if I set the bounds of my newly created form, when it gets displayed, it doesn't show in the secondary monitor.
private void button2_Click(object sender, EventArgs e){
Form1 frm = new Form1();
frm.SetBounds(-1280, 112, frm.Bounds.Width, frm.Bounds.Height);
MessageBox.Show(string.Format("frm.Bounds [{0},{1}]",frm.Bounds.Left,frm.Bounds.Top));
//frm.Bounds = Screen.AllScreens[1].Bounds;
//frm.Location = Screen.AllScreens[1].Bounds.Location;
frm.Show();
MessageBox.Show(string.Format("frm.Bounds [{0},{1}]", frm.Bounds.Left, frm.Bounds.Top));}
In the code above, I first set the bounds, I can see from the message box the settings I assigned. After form gets displayed, I checked the bounds again, it has changed to it's default. How do I show then a newly created form to a specific Bounds?
I use following .vbs can let me know the Windows Title is running or not, however, I would like to do more

I've developed a VB.NET application with Visual Studio 2008. The application communicates with SQL Server and processes a text file.
My question is about performance. While I run it from Visual Studio 2008, it takes 3 sec to complete. The same is when I run the executable created by the Setup Wizard on my desktop (Windows XP sp 3). But if I run the executable installed on a Windows 2003 Server, it takes 15 sec to complete! What could be the reason of degrading performance on the server vs. the desktop? The .Net framework 3.5 SP1 is installed both on the desktop and the server.
We have a windows service running under a network account that calls and runs an ActiveX exe. The exe is running under the local system account, not the network account of the service.

I've got an application (that is targetting .Net Framework 2.0) that is running on startup of the System, and I'm trying to get a NotifyIcon to display.When my program starts up when a user either Runs it normally or is started as a child process after the system has already logged on everything is fine.
If my application starts up as the system is performing an AutoLogon using POSReady2009 (basically XP with Single User set). Then the NotifyIcon never becomes active.If you subsequently check (in a timer) the .Visible of the Icon at any point later it always reports that it is visible = true.If you disable the SSDPSrv and restart the Computer, the Icon displays correctly.I have a sneaking suspicion this is related to .Net 3.5sp1 installed over the top of a .Net 2 system.Is there some process that I should be following to ensure that my NotifyIcon is always available to the user.I have setup RegisterWindowMessage("TaskbarCreated") but I don't get this message called, except when you forcilbly Kill Explorer.exe and restart it. Even so, a NotifyIcon interally registers for these notifications anyway, so it shouldn't be required.I'm happy to stall the startup of my program, but once the program starts up, I expect that the icon shows correctly.

View 4 RepliesCan I monitor the registry for changes similar to how sysinternals process monitor does it in VB?

View 3 RepliesI've been researching for days and I've gotten to the point where my WCF service creates an Access object via com/interop.I've ran the Open Current Database call for the Access object without an error but Application.CurrentDB is still nothing/null. If the CurrentDB is nothing then I surely can't call Application.Run "myFunction" I realize WCF services aren't meant to be user interactive, but it's a long story why I'm trying to go this route. Basically I need to have a proof of concept ready sooner rather than later and the alternative (correct) route involves the complete re-writing of a large complex access VBA application. It's not a permissions issue, I have the IIS user names added to the security tab. What I really need is a way to set Environment.UserInteractive to true so my WCF service can create an instance of Access on my server machine, run the VBA functions, close out, return true.I'm using VS 2010 for the WCF, IIS 7 for my server, Access 2010 for the VBA application.
View 1 RepliesI have a per-call WCF service that serves a number of clients. I'm looking to speed up the services by running some background processes so they don't block or slow down the main function of the services.
One example is that the main function needs to return a set of data, while the background thread needs to record some statistics based on the parameter(s).
Code:
Public Function GetAccountDetails(id As Integer) As AccountDetails
Dim retVal As New AccountDetails
Dim a As New Accounts
[Code]....
If I use this background thread to record the statistic it doesn't block the main thread from returning the data to the client.
It's been working well in test scenarios, but my question is, are there any dangers with leaving this thread to execute without Joining it before returning the data to the client? Could there potentially be any loss of statistic data? Could there be potential memory problems on the server side?
