Since you said below that it is a Windows application, I don't know how you found an AllowPaging property in VB.NET. Properties are not artefacts of the language you are using, but of a class. A control, like the DataGridView, has the same properties whatever language it is used in, and the Windows forms DataGrid view doesn't have an AllowPaging property at all.

Basically I want to use COM Interop facility and expose some functionality from my .Net application (made in 2.0 n above)to COM Client (which can be any application in VB 6.0 or c++). My requirement is when COM client makes a call to my .net component, my .Net application should start in the background and after the work is over .net application should stop automatically. So to fulfill this I will have to make COM+ Servers. Now as my component is in exe form, I understand that I will have to create a Out proc server. But in .net I don't find any easy way to register my application as out proc.
I searched the web and also code project site but not to much help. On code project site I found some useful information but the way of implementation shown is bit too difficult. (Pls visit : http://www.codeproject.com/useritems/BuildCOMServersInDotNet.asp[^])
Is there any easy way to fulfil my requirement in easier way? Pls advice.
regards,
Krunal

[CODE]
private void CreateMaze(int h, int w)
{
int r = h * w;
Room[] rooms = new Room[r];
Random rm = new Random();
int newrm = rm.Next(0, r);
int nrmcntr = newrm;
do
{
rooms[newrm].rWall = "|";
if (newrm == rooms.Length() -1)
{
newrm = 0;
}
newrm += 1;
}
while (newrm != nrmcntr);
[/CODE]
At the line:
if (newrm == rooms.Length() -1)
I am trying to compare an integer to the last index of an array of room objects.
I get the error:
Method name expected
at that line but have no clue.
Thank you in advance for any explanations.

Length is a Property for arrays not a Method
use rooms.Length-1 instead of rooms.Length()-1
good luck

i want to pass for example an employeeid which exist in the first form and on clicking the button the second form appear containing all data (firstname,lastname,hiredate,....)for this employeeid

Pass it in the constructor, or via public properties. If form2 is not a child of form1, pass it using a delegate.

Hi,
have a look at the BackgroundWorker class, that is intended for such situations.

if you are using framework 2 then i think there is some thing called parametrize thread. if you are using frame work 1.1 then have a function in a different class which doesnt take any parameter but use class level variabe in that class pass the parameter through constructor and and in the method use those mvariable. and call that method using thread.

I want to load data from sql server table to a datagridview using threading and I want to display the loading progress in progressbar. Please help.

Hi,
typically loading data from a database is a single, atomic, operation, which gets launched,
executes, and returns when done; the client simply waits while the server is
gathering the requested data. So progress information is simply not available.

I found a solution during my googling. But it is not working in my case, can any body please check this code.
this what I found:
public partial class Form1 : Form
{
public static string ConnectionString = "" //your connection string here
DataSet DS = new DataSet();
double TotalRows =0;
double RowIndex = 1;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
OleDbConnection DBConn = new OleDbConnection(ConnectionString);
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand("SELECT Count(*) from tblPersons", DBConn);
DBConn.Open();
TotalRows = (int)DBAdapter.SelectCommand.ExecuteScalar(); //retrieve the nr. of rows in the DB Table
DBConn.Close();
DBAdapter.SelectCommand.CommandText = "SELECT * from tblPersons";
DS.Tables.Add(new DataTable("Customers"));
// Add event handler to the row changing event in the dataset
DS.Tables["Customers"].RowChanging += new DataRowChangeEventHandler(Form1_RowChanging);
DBAdapter.Fill(DS, "Customers");
dataGridView1.DataSource = DS.Tables[0];
}
void Form1_RowChanging(object sender, DataRowChangeEventArgs e)
{
if (e.Action.ToString() == "Add") //check if the action is 'Add' (not 'Commit')
{
Thread.Sleep(500);
progressBar1.Value = (int)Math.Round((double)(RowIndex / TotalRows) * 100); //update the progressbar
progressBar1.Refresh();
RowIndex++; //count rows
}
}
}
}

Hi - nobody helped you 5 hours ago as your question is poorly formed, doesn't make sense and doesn't tell anybody what you have actually tried already to solve your problem.
Posting the same question again is NOT going to make sometbody suddenly thing - "oh darn, I didn't answer Thaer's question - I better do it now."
Form you questions in a clear, concise way, state exactly what the problem is what 'what you have tried to solve it' and you watch the difference.....you will not have to post it twice either. People here WANT to help - but will only help those that want to help themselves, and not those that just want their work doing for them.

i have a setup project setup1 which deploys two windows services windows
service1,windows service2.i also added some custom installation actions into
it using projectinstaller.cs.In windowsservice1 oninstall event,i attached a
database ;(create database for attach command) .
in windowsservice2 onuninstall event,i deletes the databse using "drop
database";
the setup exe installs the windows services successfully.but when i
uninstall them, the drop database does not work as sql server places a lock
on mdf files.(cant drop database as mdf file is in use).how can i solve this
problem. Also since uninstall operation is not transactional, only the
windowsservice1 gets uninstalled. when i again try to uninstall ,it shows
"the specified service does not exist as an i nstalled service"(probably the
setup again tries to unstall the already uninstalled windowsservice1).
How can i solve these problems?
i need a way to unlock the mdf files before executing drop database
command
And in unstall event of windows service 1, i need a way to check if it is
already uninstalled
public override void UnInstall()
{
how to check whether the service already uninstalled()?;
base.Uninstall();
}

Are you sure dropping the database is such a good idea??
What say you just want to upgrade the service??

No.The uninstall operation ,I mean,completely delete the application including db and registry entries .I could not uninstall the application yet.Is there atleast a way to debug the custom install actions?

I thought you were using an install shield with custom actions, the install shield will worry about all that for you!

Hi, I want to place my windows form 10 pixels from the right side of my user's screen.
But they have different screen resolutions, so i cant place it with a value in pixels.
So do anyone know how to do it?
I'm using this code on my form-load, to place the window:
<br />
this.Height = 175;<br />
this.Location = new Point(0, Screen.PrimaryScreen.WorkingArea.Height - this.Height);<br />
Thanks,
Elias Sorensen
