I don't know exactly what you mean, but if you mean the size of the string array, I had used a string array that contains 1000 line and another one that uses 100 line from the txt file, and both give me the same result.

Get ProcessExplorer or a similar tool and monitor the asp.net process that is running your webservice, I think that IIS is restarting the process due to large amount of RAM usage. I got the same error uploading large files by calling a webservice, chunk by chunk. A solution is to use free the memory from time to time by calling the Garbage Collector.

Hello,
As you know helpprovider component helps you to integrate help 1.0 files in the application. These are chm or html files. Is there a way to integrate help 2.0 files (hxs, msdn style help) into my windows forms application? So that it opens at specified place in document explorer like it happens in VS 2005. Thanks

Hi I have created a a service project in C#
It was installed perfectly. When the service started, It is giving error as "Could not perform requested operation for the Service "ServiceName" in local machine.

If I remove the 2 line:
The service is installed and starting and stoping.
If I put this 2 line,m Service is installed but not starting. It give the following error:
"Could not perform requested operation for the Service "ServiceName" in local machine.
Please help me. Thanks in advance.

My first guess would be whoever you set up the windows server to run as, that is the username and password does not have rights to do what you are trying to do.
Hope that helps.

Thanks Ben!!!
In effect when I try to start the service I
receive an error that says something like that: "The DataBaseService
service on the local computer has been started and then stopped. Some
services stop automatically if there aren't operation to execute, for
example ........ "
|
|
|
|
|
Most of the time when I get that error, it means my username and password are not valid. That is not a good message to get. You want to get sevice started successfully.
Ben
|
|
|
|
|
But I changed the Account Properties to: LocalService
Still I am getting the same error
|
|
|
|
|
I don't think you want it to run as localservice. I was set up a new user and password for that server with the correct rights on the computer to do what it needs to do.

Thanks Ben.
The Code works fine if I remove the 2 lines from the Start Method.
QuoteServer.QuoteServer quoteServer;
quoteServer=new QuoteServer.QuoteServer(@"C:\Documents and Settings\sumantar\Desktop\C#\C# Experiment\QuoteServer\quotes.txt",4567);
quoteServer.Start();
Even the start method is not having any thing
public void Start()
{
}
Without the above 2 lines the code works fine. When I put these lines, It gives error
|
|
|
|
|
If you take those two lines out of the start method then your window service doesn't do anything. I don't know what a quoteserver is, but I am guessing the user that the windows sevice is running as needs to have some rights. I would guess by default what ever user you are using doesn't have rights to your personal desktop. I would suggest creating a folder called C:\temp Put your quotes.txt file in c:\temp and change your QuoteServer call to point to c:\temp. Or set the user and password as you since you have access to your own desktop.
Hope that helps.

For this i used GroupBox with Label control and some effects to expanding and collapsing it.
Then when i used this usercontrol in one windows project, I couldn't add controls to it! I want to add controls like button from toolbox to it in design time by drag-n-drop.

i created a remider project. But now all I want is when its 1 oclock, the program display a pop up message "Testing!!!" even if the project is close.
|

|
If the program is not running it can't check time and display pop-up
|
|
|
|

You can either use SchTasks) to schedule the start-up of your application at givent time or write you own service to do that.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Add a timer, handle its Tick event, compare DateTime.Now.Hours to 1 or 13 and show a MessageBox.
If it your timer continues to fire Tick events when the MessageBox is still displaying (while you are sleeping for example  ) then you should create a custom Message Box from Form class and store a reference to it in you application like:
Reminder : Form
{
}
MyApplication : Form
{
Reminder reminderForm = null;
myTime_Tick(...)
{
if(reminderForm != null && !reminderForm.Disposing)
{
reminderForm.Dispose();
reminderForm = null;
}
else
{
reminderForm = new ReminderForm();
reminderForm.Show();
}
}
}
or you should be able to just hide and show the reminder form instead of disposing and recreating it.

Take a look at the documentation of the WebRequest.Create method.

Thnx so far.
I've checked the WebRequest.Create method. What i want to do is, take the response of the source url put it in the variable and download the csv file to the destination file. De destination is also in a variable.
|
|
|
|
|
Call GetResponse on the WebRequest returned by WebRequest.Create. The returned WebResponse has a GetResponseStream method that returns an instance of the Stream type that lets you access the response data. Read from that stream and write the content to another stream representing the csv file.
