My project requires that a windows service checks up a table on a sql database(MDF) and if product existence is 0 then sends an email to some mail address and keep checking every 24 hrs.Now Im able to send mail messages but what Im not able is to make the service itself to work or at least make sure that is working.I do the following(correct me if I do something wrong or missing a step):
1. create a new project and choose windows service
2. add a timer and set to 4000 ms just to test not wait the 24 hrs lol
3. then open its event timer_elapsed and put some code on it, like a msgbox that would keep spamming every 4 secs just to test
4. at the event onstart I enable the timer by: timer1.enabled=true
5. at the event onstop I disable the timer by: timer1.enabled=false
6. right click then choose add installer
7. in the newer installed with the two objects:
a. serviceinstaller1 set its properties to: displayname: myservice and servicename: myservice
b. serviceprocessinstaller1 set account property to LocalSystem
8. build the project and install it by opening the VS console and type: "installutil c:path blah blahservice.exe" then hit enter
9. all successfull installed open the pc manager and run the service from the list and this should be the deal
Now my real problem is that by following those steps my service is sucessfully builded, installed, and started but after the 4 seconds no msg pops up so this leads me to think that is not doing anything or I did something wrong in the steps above. Is there another way to test if this service is working else than the msgbox or the log entry? Plus, Im working on my home pc which is a xp OS. I tried the same at college pcs wich are win7 and when I did install by the console it returned an error weird but in my home pc it doesnt(and I have to present my project at college at college and tomorrow
i have written hundreds of programs with vb.net 2008, but never a service before. I have a simple service written that basically just rights a entry in the eventlog to test. No coding/compiling issues. I run the "installutil.exe" and I get a error ever time. So I went back and added the "Add Installer". But I am sure of what else I need to do, as I get the same error. Please assist.

My VB app will not work properly on a Windows 7 64 bit PC.When I launched it on the Win7 PC it will open up OK but when I open a crystal report, the form page comes up ok but the report is missing.Then I get a pop up window asking me for a user name an PW:
i just want to know how i can make this program run proberly. if you import a file in the listbox and you wanne start it whit the process.start methode it won't work. here is my code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click OpenFileDialog1.ShowDialog()
[code]....
My question is how can i make the process.start work properly and will the program start the file?
I am working on a Windows Service project that is supposed to start automatically with Windows and it has a timer to check if a certain process is created (in this case "iexplorer") the service should terminate that process. In addition, the user should not be able to stop the windows service.
I was able to create the process and make start with Windows. I changed the property (CanStop) to False but that did not help because after a few tries the servise stops. I used a For-Next loop in the timer to check for the process to terminate but unfortunatly, it didn't work. The code I used is:
Dim theProcesses() As Process = System.Diagnostics.Process.GetProcessesByName("Iexplore") For Each currentProcess As Process In theProcesses
I completed my VB project a while back and it worked great in XP.Now the same program is needed on computers that have Win7 installed.The program installs without any problems, but when I open it, it gives me an error saying the database is not accessible.
I used Visual Studio 2008 and SQL Compact to design the project.The database was included in the project and in the installation file. I also checked the Programs folder and the database was installed correctly into the correct path.What is the problem with my programs compatibility with Windows 7?
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.
I'm trying to make a LAN IM client using the net send command and I was wondering if there is any way to capture the text of the messages received through net send and display them in a label.
I am using a backgroundworker to start ffmpeg and trying to use a progressbar.ProgressBar1.Value = e.ProgressPercentage does not seem to work probably because the way ffmpeg uses standard error to report progress. I think i could use the output text to do the trick. the output.Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.92 (359/12) [code]
I have myself a self-hosted WCF server setup, which serves a clientaccesspolicy.xml and an index.htm which is just points to my xap (accessible via app.xap).
I'm currently serving them via the following code: Public Function GetPolicy() As System.IO.Stream Implements IClientAccessPolicy.GetPolicy WebOperationContext.Current.OutgoingResponse.ContentType = "application/xml" Return New IO.MemoryStream(IO.File.ReadAllBytes("Server Files/ClientAccessPolicy.xml")) End Function Public Function GetIndex() As IO.Stream Implements ISilverlightServer.GetIndex [Code] .....
It works, does the job I'm after. However, I don't think this streams the xap properly, and I know it's a streaming type. If this isn't streaming it properly, how should I stream it? (The endpoint that the XAP and index.htm files are coming through has a webHttpBinding binding). Is it being streamed properly? Or should I make some changes?
i've got a problem here whereby my ctype doesn't work.firstly, to replicate my case briefly, i've created an extension of control class
[code]...
father.getheight 'compiler writes: Panel class doesn't support getheight, but I've already converted it to a Control with CType!end sub of course if i dim father as Control it works perfectly, but in my case father may be other objects as well that aren't controls so I had to dim father as a general object, is there a fix so i could properly convert father into a Control object?
I'm using the IsBusy property to determine when a backgroundworker has completed. In the RunWorkerCompleted event I assing the result of the RunWorkerCompletedEventArgs to a public variable within the module where the backgroundworker events reside. The trouble is, the IsBusy property occasionally becomes true before the public variable gets assigned the value of the RunWorkerCompletedEventArgs. I experimented with putting a Threading.Thread.Sleep(10) after the IsBusy property becomes true and it seems to fix the problem. But it really doesn't seem right that I should have to do this. What is wrong here? I have placed the backgroundworker events in a component that is instantiated from the windows form, instead of placing the background worker events within the code of the form itself.
Here is my code;
Function SendAndWait(ByVal IntegerArray() As Integer) As String Component.BackgroundWorker.CancelAsync() Do While Component.BackgroundWorker.IsBusy
I'm working through a programming project, which should be quite easy but im stuck right at the start (relatively new to VB). I have a textbox (named textbox1) and a checkbox next to it. I want the checkbox to be ticked (.checked) when ever the value in the textbox is between 1 and 100, the checkbox to not be ticked when theres nothing in there, and for it not to be ticked when the value is < 1 and > 100. Figured a case statement would be the easiest. (this piece of code is just a validation check, basically in the real thing the user would have to enter in a value between 1 and a given number, and need to tell the user if that value is valid).
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged Select Case TextBox1.Text Case Is = ""
[code]....
But what happens is, if I enter in the value 1 in the textbox, the checkbox becomes ticked, as it should. It tick with any values between 2 and 99 (any number not starting with 1) but the checkbox becomes ticked again when the value is 100. For any other range, say 1 to 70, the checkbox would be ticked if the value in the textbox is 1 to 7, or any number starting with 1 or 7, but not 8 or 9, or any number starting with 8 or 9.
I found a class that saves column order and column width for a list view but i cant get it to work properly.
Public Class cListviewHelper Private Declare Function ListViewiColumnOrder Lib "user32" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal Msg As Integer, ByVal wParam As Integer, ByRef lParam As Integer) As Integer[code].....
It saves the right number of columns but not in the order they are.It always saves them like this in the registry "0,1,2,3,4,5,6"
I wrote a program which is editing data from database. I used few tutorials (I`m beginer) and everything is working fine(I can make changes in datagrid). but when I`m trying to save changes made in dataset(e.g. save added record) I can not to that (there are no changes in my access database, but inly in datagrid)what is interesting when I delete record - changes are saved and record is deleted from db. where is my mistake? what is wrong? maybe some tips what can I improve in this small program?

I am trying to communicate with a Windows service on a remote machine on the network but i keep getting an exception saying the following: "System.InvalidOperationException: Cannot open Service Control Manager on computer 'machine001'. This operation might require other priviledges. ---> System.ComponentModel.Win32Exception: Access is denied.
Is it possible to have a dotnet windows service which monitor other services and upon stop of any service, the monitoring service would be able to start the stopped service.
In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
I have a user control with an embeded DataGridView. I exposed the Columns property so that the columns collection could be edited in the visual designer:
