I am writing a service (service.exe) which I will be installing multiple times on a server with different display names (service1, service2,... servicen).Based on the display name the service will perform slightly different operations (e.g. monitor a different COM port).How can I programmatically determine the display name to find out which instance is executing?

View 3 RepliesI've found various C# examples here, but I can't seem to get a VB version working.I want to be able to pass a simple variable into a User Control to determine whether it shows a certain section of data.It's basically a Customer Data form, and in some circumstances I need to show a line with the customers account number and sort code, and in some I don't, so my user control:
<controls:customerForm ID='customerForm' showBankDetails="no" runat='server' />
But I can't work out what to do with the showBankDetails variable in Code Behind to stop it from rendering that section, or simply hide it with a CSS snippet.How do I access that variable in the code behind using VB.NET?
I am not sure how to do this, I need to output what service pack is installed on a windows 7 machine along with what antivirus is installed. Any idea on how I would get that information using VB?

I have a page that allows users to "upload" a file. The page includes an asp.net fileUpload control. However, all it does is send the byte array to a WSE 2.0 web service. I can't change this. This may be updated in the future, but for now, this is what I have to go with.The page has an animated gif that starts when the user clicks the submit button. And the page should be updated accordingly based on the result returned by the web service call. I'm able to start the gif and consume the WS successfully. However, while the page is hitting the web service, the gif file freezes.
I then tried to use a separate thread to consume the web service. This speeds up the process and does not freeze the gif, but the page is not updated when the web service completes. If I put the main thread to sleep, the page updates, but I'm back to the same issue mentioned above, where the gif freezes. I'm pretty sure I could make the call using javascript and update the page that way, but at this point, I'd really rather do it server side (out of stubbornness if nothing else).

View 3 RepliesI'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 1 Repliesi have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be

interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I have a multi-processing application that kicks off up to 4 threads at a time to process data into a SQL-Server database. It seems to work okay, except at times the processors are pegged at 100% and all threads slow down a bit.
So, what I want to do is conditionally fire a thread based upon the processor load... if they're already running at 100%, it makes no sense to kick off another thread.
Is there a way to determine what the processor load is? Task manager shows processor load, so there probably is... but how do I do it?
I know this is just a simple question but I could hardly find the value for the buttons in msgbox for code execution.I tried to use codes I did in vb6 and was able to execute the codes properly but when I started vb2008 I encountered logical error for these codes.Let me take you alook for the codes:[code]When you click the yesbutton it executes the Statement1 but if you click the nobutton it should only execute Statement2.
1.Why is it when you click the nobutton it would still execute the Statement1 instead of Statement2?
2.What would be the right If..Then...Else statement should be used to execute it properly?
I have Visual Studio 2008/VB application that opens Excel workbooks, reads all the sheets, and writes some data to a SQL database. I need an easy way to determine if a sheet has any data on it. By default most books has three sheets (Sheet1, Sheet2, Sheet3) and usually, but not always, my books have data only on sheet1. But i need to look at alal sheets to check for the existence of data. I know I can do a nested for loop from 1 to columns.count and rows.count, but that would take a good bit of time since those numbers usually are something like 256 and 65K.
Is ther some easy way to determine if there is any data on the sheet? If there is, is there an easy way to find the "first" cell with data in it?

View 1 RepliesIs it possible to have a sub that is triggered when any control of a specified type is clicked (or some other interaction), and then within the code of that sub, determine the sender and depending on the sender perform an action?For example, you create buttons dynamically, and assign them a name based on a counter that tells the number of buttons on the form. Now you click on a button, but there was no code written for 'button123.mouseclick' specifically. Instead, you get the name of the sender (button123) and you do something specific to that button.[code]
