Windows Service To Import Data From CSV Files Dropped Into A Directory?
Jul 26, 2011
I am writing a Windows service to import data from CSV files dropped into a directory. One of the steps is to load an XML file with validation rules which I load into a List(Of T). It will pull the data, and then I have it pass the list to a class that monitors the folder and processes the files. After that I clear the list and read in the next file configuration. Now I have noticed that the validation rules aren't matching up and it seems that the list is being passed as a reference type even though the signature is of a value type.Is there anything I can do to get around this?
[Code]...
So here when I pass it, at first it will have 3 validation rules in the new ImportService class I created, but when I call fields.Clear(), it wipes out the class member of the ImportService class.

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 VB.net web service that returns JSON that works fine. Once the response gets to a certain size though, the client browser says that the server has closed the connection and sent no data. This is true using IE, Chrome, or Firefox. The magic size seems to be about 16383 records, or about 1.13MB of data. I know this is slightly large for a web service.

For some reason the Current Directory of my windows service is C:WindowsSystem32
and when I schedule my service I get this error Access is Denied.
In one of the blogs I saw this peice to change the current directory. But I am not sure where to place this code.
System.IO.Directory.SetCurrentDirectory(System.AppDomain.CurrentDomain.BaseDirectory)

I have created a windows service in VB in visual studio 2008. The purpose of this service is to copy files from one network drive to the UNC path for a sharepoint file location. It works properly on a Windows XP machine, however when I installed it on Windows 7, I am now getting Access Denied error messages. In troubleshooting, I tried to simplify things to see if I can see the directory that I'm trying to write to, and the System.IO.Directory.Exists is returning false. I am able to see other netowrk shared drives, just not this particular one, and it appears to only be an issue from my Windows 7 machine, as I can do this with a Windows XP box.
I have also tested this code in a Windows forms application and it will work as expected. It appears only when I move to the service.

I have a PictureBox control (in Form3) that is used is used as a drop box where the user can drag and drop one or more image files at a time. When the user imports files, the form (Form3) will close itself.Meanwhile,the application stores file data in Form1.ListView1.The following is the code that I use for PictureBox's DragDrop event.
'Form3.PictureBox1_DragDrop
Dim s As Array = e.Data.GetData(DataFormats.FileDrop)

I have written a service to run an exe.What I have also tried to do is check if the file is present on the local computer, and if not copy it from a networked drive to the local computer.
If File.Exists("\\static1\software\testapp.exe") = True Then
File.Copy("\\static1\software\testapp.exe", "C:\Program Files\Testing\testapp.exe")
End If
I have previously ensured that the directory exists.When I run this as a service, it doesn't work. No errors are thrown up, but the file is not copied.When I put this into a windows forms application it works fine.
I have used:
Imports System.IO
In the header. why this won't work?
I have also tried:
My.Computer.Network.DownloadFile("\\static1\software\testapp.exe", "C:\Program Files\Testing\testapp.exe")
And that also does not work.I am trying to run this on Windows XP Professional.

So essentially, I have this text editor. How can I make it so when I drop a text file over it, it opens it in textbox2? Or when I doubleclick on the file, it automatically opens it in my program (in textbox2).

I've been developing in .NET (VB, C++, C#) for a number of years, but I am finally creating my first service application (in VB). I need to read/write to a file contained within a user's documents. As a service is not associated with a particular user, would a service have access to a user's documents? ...regardless if that user is signed on or not?

My application is often used to import volumes of data. The application currently supports .CSV, .XML, and XLS. The question relates to handling EXCEL files. Specifically, what are the best practices for coding?
Today, since customers are beginning to see .XLSX files coming in, I modified the code to use either JET.OLEDB.4.0 or .ACE.OLEDB.12.0 depending on whether it was reading an .XLS or an .XLSX. My instincts tell me that cannot be the correct way to go about this. First, customers still using Office 2003 are going to have to download the AccessDatabaseEngine in order to read the .XLSX files. Second, what if a customer installs Office 2010? Are they going to have the 12.0 stuff or am I now faced with another issue.

I am using data grid view in Vb.net and would like to load two excel files into it. My two excel files look like this:
[Code]...
The problem I want to solve is the following:I would like to map the values from the data set in file 2 to the sorted data set from file 1. So for example If I want to sort all the data by id# descending then (using the example from above) the data in datagrid view1 and in datagridview2 should be reversed.
Right now if I sort the column from file1 in datagrid view all the other columns in THIS datagridview1 are also sorted in relation to column2. What I want is that the columns in file2 will also sort according to file1.

I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.
A simple template example:
{<prt_Mark>:G} {<prt_Qty>:F2} {<prt_Length>:F2} {<prt_Remarks>:G}

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 want to build a service that "listens" for data coming in from various ports which then moves the data to the main application.To manage the settings for these services, I want to create some sort of custom management console to change the settings, start/stop the service and view the incoming data.Since you can't test the service in debug mode, would you suggest building all the logic in a win form app, making sure it works before you move the logic to a service project?Secondly, how can the incoming data being read from the service be propagated to the management console application for users to "test" and view the data?

I can reference the local (generic) data directory for an SQL file as follows:
Dim
T01Database As SqlCeConnection =
New SqlCeConnection("Data
Source=|DataDirectory|Test File.sdf")
I get a "file not found" error when trying the same syntax for referencing an Excel file:
Dim
T01Workbook As Microsoft.Office.Interop.Excel.Workbook
= T01Application.Workbooks.Open("|Data Directory|Test File.xlsx"
)
correct syntax for referencing an Excel file in this manner?

I'm experiencing a weird problem. I need to create a Windows service that listens to a port for data. The data is comma separated, so I need to split it up and just write a few of the separated values to a file. This is a brief summary of my code:-
Do While True
tcpClient = tcpListener.AcceptTcpClient()
networkStream = tcpClient.GetStream()
Dim bytes(tcpClient.ReceiveBufferSize) As Byte
[code]....
Now the above code works fine. But suppose I just want to write only (2) to file i.e 2 of the comma separated values, problems arise. This is what happens:-
If I include both lines (1) and (2), output file = lines (1) and (2)
If I include only line (1) and comment out (2), output file = line (1)
If I include only line (2) and comment out (1), output file = BLANK ???

I have written a windows service that uses sockets to send receive data, it works fine when the server has been running and all other services have started, but after a reboot it does not work. Now I know its probably dependant on another service and I know how to add dependencies, but how do I work out which services its dependent on?

When you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?

I am going to need to create a windows form for work that we can connect to a database table, select a directory and move files from the directory that are in the table and move to another folder. The directory will have sub directories that I need to search for the file name and move. I would like to have the table hold the file name (or path) and move all files that are in the database. There might be 20 files or 1000. Depends on the client we are processing for.
