I have a third part dll COM that communicates with my C# program through the interop.
I launch my program and it works correctly.
Then I attach some events that dll COM can fire. I do nothing in those events.
Now I launch my program and it leaks.
Is there a known bug firing events from COM to .NET or using interop?
Thanks in advance.

Hi All.
I'v got a problem with vertical scrolling in Win form DataGridView control.
I show about 40000 rows and make it by binding rows to a DataSet.
Some time the DataSet needs to be refilled from database and I run refilling function in a new thread. Then I initialize a datasource property with the new dataset. The datagridview shows my results but the vertical scrolling seems to be disabled. It doesn't react to my mouse clicks and even doesn't show a scroll on the scrilling bar. But if I do not use the thread everything works fine. Does anybody know a workaround? Please help.
Here is my code:
ThreadGetDataSource TGDS = new ThreadGetDataSource();
TGDS.Query = query;
TGDS.CallBack = SetDataSource;
Thread t = new Thread(new ThreadStart(TGDS.ThreadProc));
t.Start();
public void SetDataSource(DataSet DS) {
if (DS != null && DS.Tables.Count > 0)
this.dgView.DataSource = DS.Tables["Data"];
this.dgView.Refresh();
}
public delegate void SetDataSource(DataSet DS);
public class ThreadGetDataSource{
public SetDataSource CallBack;
public string Query = string.Empty;
public void ThreadProc() {
DataSet DS = GetData();
CallBack(DS);
}
public DataSet GetData (){
DataSet DS;
DataTransfer DT = new DataTransfer();
DS = DT.GetDataSet(this.Query, "Data");
return DS;
}
}
I tried to use methods Update, Refresh of the DataGridVew but it doesn't help.
Tried to call Refresh on DataBindingComplete event. Doesn't help either.
Thank you.
My best regards

How did this differ from the other query you posted at this permalink [^] just about three minutes back?

It doesn't. It's a duplicate.

Please don't duplicate posts. If the second post was accidental, please remove it (but only if there are no responses) otherwise remove the first post (again, only if there are no responses). If it wasn't accidental, you need to realize that the people here answer questions on a volunteer basis and will probably not respond in a timeframe you desire or find acceptable.

 hello sir,
i am new in .net. i had made a window application in c#.net
as front end and sql-sever as back end.
now the problem is that how to install sql-server ,.netframework,and execute sql-script and my project on client computer step by step. plz give me details .
your shuaib

I doubt you're going to get a step by step runthrough. This is quite a length topic, and there are several good articles on this. Try searching on google for details on .net setup with sql server.
Deja View - the feeling that you've seen this post before.

I write a C++ program which does the installation of the framework, etc, then I'd build into my app or write a seperate app that runs the scrpts to create the DB.

I have created an add-in to Visual Studio 2005, and I would like to use a WCF service.
This requires a configurationfile with the configured endpoints. Normally I would create an app.config, and let visual studio build it to [appname].config in the output directory and it would work.
But when I try to access the services from the add-in, i get a configuration error that the endpoints are not configured. How do i make it open the configuration for the add-in, and not for Visual Studio?
With kind regards

If I'm in the wrong place or this is a stupid question I apologise in advance.
I am having to write a data acquisition program in .NET (C#) before I’ve had time to learn it which is making for some interesting code. What I would really like to do is reference a group of 24 progress bar components within a for/next loop using the index of the loop. Does anyone know how to do this? The code I use at the moment is very inelegant and bugs me. Would appreciate any pointers (sorry ‘bout pun)

Wow Ted, that just sounds horrible. But given your situation:
sysrev wrote: before I’ve had time to learn it
and
sysrev wrote: a group of 24 progress bar components
With that situation I would go with "if it works, I don't care".
|

But I'll need to do it again somewhere - and again, and again.........

Hi,
hard to give a good answer without knowing your exact situation. You could add all progress bars to a List<progressbar>. After you have done this once you can iterate the list with for/foreach or whatever technique you like.

Thanks for the suggestion Robert.
The progress bars display the output of a pressure sensor over a 24 hour period. When I get a new reading, I shift values chronologically "down" one bar and put the new value in the "top" (most recent) bar. The coding begs for an iterative loop but I don't know how to address the bars name property with the index. So I ended up using a switch construct which works okay but is awkward to maintain.
The List class is new to me and on your suggestion I had a quick look at it. I must say, it does not look promising but will try it out if I can.

Hi,
I'll try to outline what I meant:
private List<ProgressBar> _bars;
_bars = new List<ProgressBar>(new ProgressBar[] { pb1, pb2, pb3, ... });
for (int i = 0; i < 24; i++)
{
_bars[i] = someArrayWithTheValues[i];
}
With the mod operator you could also easily switch which hour should be displayed at the top:
int hourToDisplayAtTop = 4;
for (int i = 0; i < 24; i++)
{
_bars[i] = someArrayWithTheValues[(i + hourToDisplayAtTop) % 24];
}

I think I can see what you are suggesting and am trying to experiment with it in a new application as here:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace IndexComponents
{
public partial class Form1 : Form
{
private ProgressBar pb1;
private ProgressBar pb2;
private ProgressBar pb3;
private List<ProgressBar> _bars;
public Form1()
{
InitializeComponent();
int[] someArrayWithTheValues = new int[3] { 1, 2, 3 };
//Field declaration in the Form/UserCotrol
/// private List _bars;
//somewhere after the InitializeComponents call
/// _bars = new List(new ProgressBar[] { pb1, pb2, pb3 });//when you want to update the bars
_bars = new List<ProgressBar>(new ProgressBar[] { pb1, pb2, pb3 });//when you want to update the bars
for (int i = 0; i < 3; i++)
{
_bars[i] = someArrayWithTheValues[i];
}
//With the mod operator you could also easily switch which hour should be displayed at the top:
int hourToDisplayAtTop = 2;
for (int i = 0; i < 3; i++)
{
_bars[i] = someArrayWithTheValues[(i + hourToDisplayAtTop) % 24];
}
}
}
}
I am now working on the last two(I hope!) build error which are flagged within the two for loops as below:
Error 1 Cannot convert type 'int' to 'System.Windows.Forms.ProgressBar'
Error 2 Cannot implicitly convert type 'int' to 'System.Windows.Forms.ProgressBar'
