You sure do, as you seem incapable of using your own abilities.

Wrong site. Try rentacoder.com, they do your work for you. The idea of CP is to answer specific problems, not provide free code for people to pass off as their own work, either for college or when they have assured a client they can do it but haven't got a clue.

- Dont put "Urgent Help Required" or somesuch. It's in the FAQs/ How to post a question sticky at the top of the board
- Don't expect us to supply you with source code. Describe your problem and what you have tried. It's in the FAQs/ How to post a question sticky at the top of the board
- You can't really expect anyone to provide an entire system for you? If this is a college project, we should get the credit (and qualifications) for our work, not you, also if you don't do it yourself you won't learn anything. Assuming it isn't a college project this is, after all what you are getting paid for , so anyone writing the system has a reasonable expectation for the same

Hi,

Btw. this is an C# forum, and you posted some VB code. Also try to not double post.

I have created one text file in File Contain -> "abc or some value"
Account :LocaSystem
protected override void OnStart(string[] args)
{
if (!File.Exists("C:\\DevLog.txt")) {
EventLog1.WriteEntry("File Not Exist"); 5. }
else {
StreamReader sr = new StreamReader("C:\\DevLog.txt");
string tempstr = sr.ReadToEnd;
if (string.IsNullOrEmpty(tempstr)) {
}
else {
EventLog1.WriteEntry("Get File Name");
st = tempstr;
}
sr.Close();
}
}
the error msg is:---Service cannot be started. System.IO.FileNotFoundException: File not found.
I think you get clear idea about problem ...
Thank for reply

So its not necessarily that it can't read your file. Comment out all your code to do with the file and just write a message to the eventlog to show your sevice is working. Then you will make some progress.
There should be no problem reading a file, many services are file watchers, waiting for files to process.

Without File handling code it will working properly and also get proper eventlog up to the File.Exist()
Thanks for reply
|

So now try just checking for file.exists and logging a message. Put it in a try ctach so you can log the full exception details and that should give you some pointers.
Really, this is a basic programming technique for trapping/tracing errors so you should be able to properly identify where it goes wrong and also get the full error message as to why.

You can use Events to trigger the status of the buttons based on the tree view node.

I wrote class library (dll) and this library contains one singleton class. Like this;
public class MyList : List<string>
{
private static readonly MyList m_Instance = new MyList();
private MyList()
{
}
public static MyList Instance
{
get { return m_Instance; }
}
}
Client --- WCF --> Server; add item to MyList class, its properly work.
Another Client --- WCF --> Server; add item to MyList class, its properly work.
But;
I have a thread in server side. If this thread add to item to MyList, clients items not contain in the MyList. Actually main problem is I can't see MyList items which are aded by clients in server thread.
I think this problem related about AppDomain. How can I solve it?
Best Regards...

Doesn't the server exit the application after the first client does its thing?

My WCF Service use TcpBinding and host on windows service. I am not use ServiceBehavior InstanceContextMode... Problem not related about WCF.
I wrote class which is MyClass1, this class in server side. This class have a Start() function.
public void Start()
{
Thread thread = new Thread(new ThreadStart(CheckTablesAreChanged));
thread.IsBackground = true;
thread.Start();
}
private void CheckTablesAreChanged()
{
while (true)
{
... ADD ITEM TO MyLIST CLASS ...
}
}
Start() function call when WCF is hoting like this;
host.Open();
MyClass1.Start();
So this side not related about WCF.
In Client side;
Client --> WCF --> Server --> ADD ITEM TO MyLIST CLASS
For example client add 3 ITEM TO MyLIST CLASS, after that I check MyLIST CLASS count property in "CheckTablesAreChanged()" function, MyLIST CLASS count is 0.
