His spelling is correct. You appear to have reposted a question to get it further up the message listing. This is considered bad form (rude)

My spelling is correct. What I am saying is that it is rude and disrespectful of other posters when you attempt to bump your post (hence it's bad form).

That is bad form AGAIN. It sounds like you are demanding that he help you. He doesn't owe you anything. No one here does.

About your question. That fact that people cannot understand your question is your fault, not theirs. Perhaps you need to study the technology you are attempting to use so that you may pose questions using knowledge and standard terms that people will understand.

I have several list collections(i.e list1,list2 list3...etc)
and i have one xml file(i.e data.xml).I am storing the xml data to my suitable lists(i.e edge data in list1, subpart data in list2 like this...)
Now after storing the xml data in list collections i want to save this data from list to data base.
Till my coding is doing fine working properly and date are geting save into database.

But this entire process is time taking and user does not know when this process will completeed.Basicaly the xml file is not fixed.i will get sevaral xml file with more or less data(data structure of xml file is same).

I want to implement the progress bar here to inform how many hours or minutes or seconds left to to finise the entire process from storing xml data into list to saving data in database

can anyone give me idea about it...

with regards
tarak

You can't really do this. When you think about it, progress is dependent on many factors outside your control, such as network latency, server load, type of operation to be performed, other processes running on your machine, and so on. So all you can do is give (at best), a rough approximation of how long it will take.

Most algorithms work by knowing how many operations need to be performed, and then start by calculating how long one operation takes - then extrapolating the total time from this. After a certain number of operations, this figure is refined because there is greater statistical sampling at this stage. This is done over and over, until the operation is finally completed.

Style of a DataGridView.Row by using DataSet

The following code shows you how I created a DataSet and added it to the DataGridView.
To define the default column style, I added 2 columns to the DataGridView before and set their DataPropertyName.

<br />
DataSet ds = new DataSet();<br />
ds.Tables.Add();<br />
<br />
ds.Tables[0].Columns.Add("a");<br />
ds.Tables[0].Columns.Add("b");<br />
<br />
colColumn1.DataPropertyName = "a";<br />
colColumn2.DataPropertyName = "b";<br />
<br />
for (int i = 0; i < 10; i++)<br />
{<br />
    ds.Tables[0].Rows.Add("a" + i, "b" + i);<br />
}<br />
<br />
dataGridView1.DataSource = ds.Tables[0];

Now I have the problem that I can't change any style (BackColor) of the rows that will be added by setting the DataSource.
Can I define it somehow in the DataSet (DataRow) OR is there any event that will be called after the row finished adding?

[I don't want to go through each row after the DataSource is setted and set the new style]

In that way i currently solved it:

<br />
private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)<br />
{<br />
            int i = 0;<br />
<br />
            try<br />
            {<br />
dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.White;<br />
                if (dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString().Contains(textBox1.Text))<br />
                {<br />
                    dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.ForestGreen;<br />
                }<br />
                int ii = 1 / i;<br />
            }<br />
            catch<br />
            {<br />
<br />
            }<br />
        }<br />

I used the RowPrePaint event. So everytime when the row will be painted there is a check if the BackColor should be changed.
I tested it with 1,000,000 rows in fullscreen and the performance is (not the best but) ok.

But if you have another solution, feel free to post it.

Instead of trying to set the background through code its better to use CSS.

I forgot: It's a Windows.Forms application. So i can't do it in that way.

But in Websites it's also a solution.

Calling Code in Host Application From a Workflow

Hi,

I am experimenting with hosting a workflow within a Windows Forms application. From within a Code box in the workflow, I want to bring up a window in the host application, but am struggling with giving the workflow visibility of anything in the host application.

I realise it is questionable design that the workflow know anything too intimate from the hosting application, but can I get workflow code to call delegates in the host application perhaps? If so, what is the best way of 'passing' these delegates to the workflow.

Or am I missing some fundamental generic method that I should be using for doing stuff like this?

Any help or advice or pointers to good articles on this would be very much appreciated.

Best wishes, Patrick

Just a question on your design (that you mentioned is questionable Big Grin | :-D

), workflows are normally not in a presentation layer and run as background functionality (hence can be called by any application, forms or ASP), are you sure you want to run the workflow in the presentation layer?

The app I am developing (actually it is just an experiment at the moment) is similar to a Windows Troubleshooter. I was thinking of using the Workflow to provide the flowchart logic, while the Forms part simply acted like a dumb slave, providing functions such as AskQuestion(). As I say, it is all something of an experiment at the moment. I am just seeing how it would all fit together if I were to go down this route. On the face of it, it does seem to be ideally suited to this type of application.

Write a Xsl and bind your Xml data to this xsl.

You can use XmlTextReader object to read and parse XML files and display accordingly.
