I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:

VS 2010 To Window Service Or Not To Window Service?

Jul 20, 2010

I am making a server program, it works, cool.Made it display the info coming in via a textbox, the number of users connected, etc.I based it off of one of the members heres examples (jmcilhinney).However, I am kind of in a rock and a hard place.Do I try and convert it to a windows service so its on all the time? Or do I leave it in a exe format?I have never touched windows services before, but they look promising.However, this will be residing on a collocated server running Windows Server 2003.The problem with that is, if I run it. Person B, C, D, E, whoever.. can not see it due to the virtualized desk tops of RDC (even under the same username).I am kinda curious if I should make it a windows service, then make my 'display' program that just.. remotely taps into it to control it, and view stats and such.The 'server' will take info sent from the client, and add it into a database, then pass back some commands and such.

System.Threading.Timer Fails To Fire After Minimizing Window?

Mar 16, 2009

I have used timers in .Net for a long time now an never had this problem.Start timer to fire every 10 seconds that reads an object and updates the UI using a delegate.This works great until the form is minimized several times, then the timer thread seems to vanish.Anyone come across this before?

Obviously I can roll my own using a thread directly and sleeping it, however this seems like reinventing the wheel when a threading timer class exists already.
Code: Private Sub m_Tmr_Tick(ByVal state As Object)

Handle Case Sensitive Classes And Methods From A C# Web Service In .net App?

Jun 22, 2011

I am working on a VB.Net application that needs to access a web service that I am nearly certain has a C# backend. At bare minimum, the backend is providing classes to me that are differentiated only by case, and within a number of those classes, there are properties and methods that are only differentiated by case.

VB.Net is case insensitive, and it sees a number of these items as being ambiguous.I've thought of a few ways of dealing with this, but I would like suggestions before I go down a road that is likely difficult.

Here are some ways I have considered going about it.Modifying the generated code for the wsdl. This has presented problems in responding as the xml output would no longer conform to the webservice requirements.I think there might be some attributes I could use to override this, but I'm not sure what they are yet. Even so, this web service gets frequent updates and I would hate to have to keep refixing the service every time I refreshed it.Creating a csharp wrapper project where I expose the underlying classes with different names. Primarily through inheritance. Although the big problem here has been the issue with properties and methods that are only differentiated by case as well.

I'm sure at some point I could get one or the other of these solutions working, but if anyone has any better suggestions that I'm not thinking of,

Uninstall A Window Service?

So when I open VS with the project, I right-click on the servicesetup and choose uninstall and it says "This action is only valid for products that are currently installed." It is listed in control panel Services, so isn't it installed?

Accessing Properties On A Window Service?

Aug 30, 2009

If I have a custom windows service running on a server, is there anyway I can access the value of a property/variable within that service? For example, I would like to have a client vb program be able to "read" the value some variable from that service. A simple example would be the service would capture a boolean value of the success or failure of the last time it kicked off a process. I would then like to have a client windows app "connect" with the service and be able to read that boolean value.

Window Service Call A Stored Procedure?

Feb 22, 2012

I used the same lines of codes to call a SQL server store procedure to export sql data to an XML file:

1. If I call the stored procedure from a window form application, it works and generates the file at the designated location.

2. If I call the stored procedure from a window service application with a setup project, and the install process run well, and I started the service, and checked the event log, it showed the service start successfully, BUT it FAILED to generate the file at the destination folder. I also run everything as administrator, but it still failed to generate the file. It made me wonder if a window service can call a stored procedure. Because, again, mine ran fine with the window form appl, but window service, I would like to have your sample codes. I have googled around for 3 days now, but could not find the answer. I use vs 2008, sql server 2008, and Windows 7

Window Service Does Not Start All Process On Window Start?

Aug 1, 2011

We create a window service that will launch multiple process of an application with different configuration. And application further communicate with sql server. It works fine when we start service manually from service manager. It launch all the process ( try with launching 3 process ). But when we test it by restart the machine and service launch automatically then it launch only one process third one. I check the event log in event viewer. I see the following message by MSSQL$MSSQLEXPRESS service

Login failed for user 'dduser'. Reason: Failed to open the explicitly specified database. [CLIENT: <local machine>]

one thing we also tried by delaying ( with thread sleep ) the code execution of service. Then by starting machine again , it launch 2 process , first one still not launch.

Using Sender As A Case In Select Case Statement?

Mar 21, 2006

When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?

.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application

Jul 14, 2011

i 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
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
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.

.net - If Case Statement Throws Exception "case Else" Start Working?

Jun 19, 2012

It looks like impossible but...

Try
Select Case command
Case 1
smth()
Case 2

[code]....

Firstly Case 2 runs. Throws exception. And right after this debugger shows that next processed statement is Case Else. Only after Case Else throws own exception Catch block start working. I've never seen this trick. Why can this happened?I'm sure the block is entered once (not like this:first enter hit Case 2 and second hit Case Else).

Update:-To Matt Wilko. Thank you for answering. I've switch to Strict On in Options of VS2010 but nothing has changed. Command is variable, not function. Watch tool shows that on each step Command is the same ( Command = 2).

Fixed. Yeeaaaahhh. I simplefy code to
Try
Select Case 2
Case 2

[code]....

and change project to Console app. This works as I mention. The fix was in Release mode. I was debugging in Release mode. When I switch to Debug mode everything goes as it should.

.NET Application Receiving 503 Service Unavailable Error When Calling Web Service?

Apr 28, 2009

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.

Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
