You could do this two ways...either through connecting to excel file Excel on Connectionstrings.com[^] or through Office Interop...

Going the connection string route may be the easiest, but the Office Interop way is powerful but a bit too involved to post...

Like this i am now able to read the values, but i am now copying string to string. when i tried declaring s as int array and s = (int) ran.text, i am getting error

how can i convert the ran.text string to s int array

for(int row = 2; row< 12; row++) // loop through first 10 rows excel is

{
ran = (Excel.Range)Worksheet.Cells[row, 1];
s = (string) ran.Text;
MessageBox.Show(s);

}

this is working for me, i dont know whether it is correct type casting or not

You will see the code like that in Program.cs

<br />
[STAThread]<br />
        static void Main()<br />
        {<br />
            Application.EnableVisualStyles();<br />
            Application.SetCompatibleTextRenderingDefault(false);<br />
            Application.Run(new Form1());<br />
        }

So, change form1 to the form name you want.

eg:

<br />
[STAThread]<br />
        static void Main()<br />
        {<br />
            Application.EnableVisualStyles();<br />
            Application.SetCompatibleTextRenderingDefault(false);<br />
            Application.Run(new FormThatIWantToShow());<br />
        }

my application listens for socket connections. client can open socket connections and transmit messages. it connects to another server to get updates. each second my application get 300-400 data updates filters them and tranmits the updates to the connected clients same filterred 10 to 12 updates to each clients.
When 500 clients connected to my application its cpu use was 40-80% memory use 15 MB but after 3 hours I get windows error. some window apprears saying "This application encountered some problem needs to shut down. Sorry for the enconvience." Amazingly my app is running happyly no change in cpu and mem uses. When i close the error window it shuts my app.

This is a multithreaded application. I checked for deadlocks confident that there is none and .net 2 handles deadlock itself. Confident that there is no memory leaks. Application totally written in C#.
Can anybody help how to ger rid of this windows error?

How is .NET supposed to do that (generally)?

First thing to do is to find out the unhandled exception that's being thrown. Usually an unhandled exception is the reason for "This application encountered some problem...", but without the exception only looking into a crystal ball can help you.

Did you check the other properties of the process at runtime? GDI Handles and USER objects come to mind. When they're used and not disposed of correctly, the app will run out of handles after some time.
But once again: It's impossible to tell without seeing code.

#1. maybe, the parameters that you are sending from code are more than the actual parameters of stored procedure.

OR

#2. try to call the stored procedure with fully qualified name. (eg: dbo.myStoredProcedure or mydb.dbo.myStoredProcedure )

OR

#3. check-out this article[^] if you are using Datagrid view or ObjectDataSource

Hope it helps...

Why not use only 1 form if all forms are the same?

Yeah. This is the way it is.. this is like inheriting the base class. When you inherit the base class, the new class won't get the code but it access its parent functionalities.

What about creating a user control?
If the most of things (controls, layout) are the same, you may probably create one user control. Place this control in all forms.

There is posisbility to use inherited forms. (In the new item window). I tried to use this, but it does not work well with the form designer view (unfortunately). You can try to put all functional stuff in a separate class and use an object of this class in your form. You even can attach alle controls to control functionality you define in this class.

the quesion about Timer:it is Started but does not run the funtion every minute?

supercsharp111-Aug-07 21:36

11-Aug-07 21:36

I hava a page,named TaskConf,there is a System.Windows.Forms.Timer timer1,and there is a funtion named SetTmier() to Start timer1
public void SetTimer()
{
timer1.interval = 60000;
timer1.Ticked += new EventHandler(Task_refrush);
timer1.Enable = true;
}
The funtion Task_refrush is the event funtion，which is belong to page TaskConf.

In the other page login I call TaskConf Constructor，and then Start two thread to Start SetTimer and Task_refrush which ara belong to TaskConf:

TaskConf tc = new TaskConf();
.
.
.
..
...
Thread t1 =new Thread(new ThreadStart(tc.Task_refrush));
t1.Start();
Thread t2 = new Thread(new ThreadStart(tc.SetTimer));
t2.Start();
I found these two threads are all running，The code in Task_refrush and SetTimer is excuted，（TaskConf is not open，but constructed,only the page login is open）,the timer1 in TaskConf is started，but why the timer1 does not run the funcion Task_refrush every minute?Why?

Are you using Windows.Forms.Timer in ASP.NET Webpage??

If you are calling the start() function of timer in constructor of the form, Tick() event of timer will get fired without showing the form...

public Form3()<br />
       {<br />
           InitializeComponent();            <br />
           timer1.Start();<br />
       }

Slow String Arrays

Expert Coming11-Aug-07 19:55

11-Aug-07 19:55

I am opening about 70 web pages and pulling about 1000 strings from each. My arrays tend to be 60,000 to 100,000 string arrays.

The problem I am having is this is very slow. I am using RegEx to get the 1000 names from each web page, and then putting them into a SQL database.

How do I speed this process up, it takes around 20 minutes.

I think one major slow down is I am inserting them into the database one by one. Is there a way to fix this piece? Will stored procedures help?

Is there a faster way to implement a RegEx like solution to speed up the string collection?

Is the fact that I am using an ArrayList the huge slow down?

Any help, suggestions, articles, anything, would be greatly appriciated.

Thanks!
