For a C# 2010 windows service I need to check to see if files exist in a speciifed directory location at specified time intervals. If file(s) exist in the specified location, I need to accomplish the following steps:
1. I need to call some specified code for updating the database,
2. I need to find a way to indicate the files where already accessed without moving the files from their original location.
3. I need to know how to setup the windows service.
Thus I am wondering if you can tell me and/or point me to a reference that will tell me how to accomplish my goal using a windows service? I could use a different utility if you think it is better than use a windows service.

2) You may be able to set an attribute, otherwise you may need to store the file info in the database
3) How frequently? If not very frequently, like ten minutes or more, then a Windows Scheduled Task may suffice.

You should look at FileSystemWatcher

I would say that sounds like a stupid requirement. If it was me I would question that.
But you can just record the file names in the database.

You can google that.

In a C# 2010 desktop application, I need to create a dynamic directory
paths based upon the names of some documents I obtain from a web service. Basically if the name of the file type in an xml file is called 'Customer Inventory", I need to place these documents in a folder one level lower than the rest of the documents. Basically most files will end up in a path that looks like:
C:\temp\customers.
However the files that are marked in the xml file called "Customer Inventory", need to end up in a file directory path that looks like the following: C:\temp\customers\Customer Inventory.
Thus can you tell me how I can create the correct directory paths I need to work with?

Use the Directory.CreateDirectory[^]-method.

My question is how can I place the files in one directory path or the second directory path that is longer? Basically the output files can go to 2 different locations. Can you tell or show me how to determine and actually place the different type of files in the different directory path locations?

This is all fairly basic stuff. What, exactly, is your background? How did you end up with this task? Judging by the number of questions you have posted recently, it seems that you are turning straight to Code Project for solutions.

I have 2 years of experience with C# and 1 year with VB. I only ask the simple questions here. I do not place the difficult questions here since I do not think that is what this message board is setup for.

So, how do you think you should solve this problem? Talk me through the problem and potential solutions. Break it down into little steps; you'll be surprised just how easy it is to solve when you know this.

Based on your other responses.
You were told how to create directories.
You already know the name of the file you must look for. If you don't then you MUST figure that out BEFORE you code.
So now that you know the name, from your example there is one name, so you use an 'if' to compare the name of the file to the file that you have.
So the pseudo code looks like
fileName = GetFileName()
if (fileName equals "Customer Inventory")
if (! Output dir)
CreateOutputDir()
WriteFileToInventoryDir()
else
WriteFileToMainDir

I am having a problem using linq to sql in a C# desktop application that connects to sql server 2008. Basically if the CustId already exists in the Trans table, I do not want to insert a new row into the table. However the code listed below does not work.
**Note the CustId is not the primary key of the table. there is an identity key that is the primary key of the table.
eDataContext rptData = new eDataContext();
var eupdate = (from a in rptData.Tran
where a.Cust_ID == CustId
select a).SingleOrDefault();
if (eupdate != null)
{
log.Info(CustId + "already exists in the Trans table");
}
else
{
Trans subCustid = null;
subCustid = new Trans();
subCustid.Package_ID = pkgid;
rptData.Trans.InsertOnSubmit(subCustid);
rptData.SubmitChanges();
}
Thus can you tell me what I can do to not allow a row to be inserted into the Trans table when the CustId already exists in the table?

In a C# 2010 desktop I have one solution file that have 4 separate project folders. In two of the project folders I need to access two of the same tables using linq to sql. I do not know how to make each project folder be aware of the two tables. Thus I embedded basically the same *.dbml files within each separate project folder.
I do not think what I did is the best solution. Due to this fact, I have the following questions:
1. Is there some kind of a way that each project folder can have access to the same *.dbml file? If you can you tell me how to accomplish this goal?
2. One of the project folders is a proxy file. Is it a good or bad idea to have a proxy class (project) folder update a *.dbml? Can you explain your answer to me?

The solution is to create a single library project that exposes the database as an object library.
Then both of the application projects can use this library and no worry abouy what you're asking about at all.

|

Can you show me code and/or point me to a link that will show me how to the code as you are just suggesting needs to occur?
|
|

Not really. It's a matter of thinking about the problem the correct way. Think about this... you're writing a library that interacts with the database. What do you have to expose in the way of methods and return types that any application you write can use that library and not worry about how the database is implemented at all??
Try getting a book on the Entity Framework and you'll see what I mean.

The click-event simply isn't fired for a MdiContainer. Hence, what you want is not possible.

Hi,
I have an application which will be shown on TV in the customers' waiting area to show the ticket numbers.
I want to know how can I display a live TV in the same application within a panel or a component so it will be part of the screen?

There's no "TV-control" in .NET. How did you plan on getting the TV-information in Windows?
I've had a Pinnacle-TV card and that came with an application to operate it (and record to harddisk). If you have a similar app, you could use an old trick[^], I believe you used that one before.
Best would be to "search" on the COM-tabpage from the "Add References" dialog in Visual Studio. Most of those apps use a COM-component to display their stuff, and it might be easy to re-use it.

Has anyone done this? I've tried using wmi via c sharp with the namespace
\\[servername]\ROOT\cimv2\dell:Dell_RemoteAccessServicePort and haven't gotten anywhere.
Our drac IP list is not accurate and I'd like to have a program that queries a server list and gives an update list from WMI or some other source. I've seen racadm do it locally, so it must be stored somewhere that is accessible from the OS.
I just did a procmon on racadm and could not find anything as far as how it generates the drac ip when it does a query. Thanks for reading.

I'm refactoring a WinForms project. I have 2 forms that do the same thing, except the data entities passed in are slightly different, so the guy who wrote them decided to duplicate the forms instead of making one form that works for both. So I'm refactoring them.
Assume I have these 2 entites:
public class Entity1
{
public string SomeProperty { get; set; }
public string Name { get; set; }
}
public class Entity2
{
public string SomeProperty { get; set; }
public string Caption { get; set; }
}
In the CTOR of the form I have:
public partial class Form1<T> : Form
{
T entity;
public Form1()
{
InitializeComponent();
entity = (T)Activator.CreateInstance(typeof(T));
}
}
The problem is I now need to set properties on the object passed in. In most cases the 2 objects have the same name properties, but ther are differences.
What is the right way to work with this object? Seems like I have no choice but to cast.
Thanks
If it's not broken, fix it until it is

What I think you need is:
public partial class Form1<T> : Form where T : new()
{
T entity;
public Form1()
{
InitializeComponent();
entity = new T;
}
}
|
|
|
|

yes, but I still wont have access to the properties, at least without doing
Type type = typeof(T);
var prop = type.GetProperty("Name");
prop.SetValue(entity, "TheName", null);
not sure I like this because the property names would have to be listed in calls to GetProperty.
I dunno, what do you think?

OK
What you need to do is create and interface:
public interface IEntity
{
string SomeProperty { get; set; }
string Caption { get; set; }
}
Then use this interface on the classes:
public class Entity1 : IEntity
{
public string SomeProperty { get; set; }
public string Name { get; set; }
}
public class Entity2 : IEntity
{
public string SomeProperty { get; set; }
public string Caption { get; set; }
}
Then use is in the generic:
public partial class Form1<T> : Form where T : IEntity, new()
{
T entity;
public Form1()
{
InitializeComponent();
entity = new T();
}
}
