Hi,
CodeProject hosts a lot of articles on progress bars, some or good, some not.
Progress can only be reported to the user if the operation consists of multiple steps and you know (or can somehow estimate) the relative duration of each step.
If OTOH your backup basically consists of a single SQL (or other) statement, then it is impossible to report progress as there are only two states: nothing done (before the statement) and all done (after the statement).

I draw line on windows form, using following function.
private void DrawLine(Point pPoint, Point pFisrtPoint)
{
Graphics graph = this.CreateGraphics();
Pen pen = new Pen(Color.Red);
graph.DrawLine(pen, pPoint, pFisrtPoint);
}
How can I get painted points coordinates?

hi,
that is bad code for several reasons:
- when no longer needing objects that you created and have a Dispose() method should be disposed, especially the expensive ones such as a Graphics;
- Pens.Red is for free;
- within a Paint handler, the Graphics is for free, see PaintEventArgs.
- you should not use CreateGraphics except as a last resort.
I suggest you read this[^].
BTW: the pixels modified by a DrawLine are on or near the line you paint, which exactly depends on some parameters, such as SmoothingMode I guess.

What do you mean? you want to get coordinates of already pained point? (All points on screen are painted)
Or are you refering to?
pPoint.X
pPoint.Y
also Graph.TranslateTransform can affect your coordinate system

For example I write following code;
Point p1 = new Point(0, 0);
Point p2 = new Point(3, 0);
DrawLine(p1, p2);
I want to get painted Point;
"0,0", "0,1", "0,2", "0,3",

You'll need to implement you're own line drawing algorithm to return those points. There is nothing in the .NET Framework that will do it for you.

That's not strictly true - he could paint it onto a bitmap of the same size and examine the pixels.

WMI should help. Check this[^] article.

how do I use the default language in datetimepicker?
eg computer I set the default language is English! but is still datetimepicker french
|
|
|
|
|
No such thing.
Plus you should always use an ISO 8601 format, e.g. yyyy-MM-dd.
|
|

I Think that is connected to OS language. Since I am using XP with Slovenian language. And I useded DateTimePicker, I got in Slovenian names. You must be missing something. (XP have 3 difrent location settings in Regional settings) gonna tried at home, where I have Win7 english

Now i am home and i know what affects it.
Under Region And Language (Where you see date and time formats), you need to change Format to specific country

For a specific url which is opened in IE, I want the details temporay internet files (like images, textfiles, pdfs) of that specific URL. I try to retrieve all those information through wininet functions like FindfirstURLcacheEntry, FindNextURCacheEntry, GetUrlcacheEntryInfo,
I tried to make a log about all the details which can be obtained from temporary internet files for that specific url, I observed that I was unable to get the PDF path which exists in temparary internt files.
How can I get this,
Is there any other method to get that PDF?
If anyone knows something, plz suggest some solution. thank you

I would use HttpRequest class to request the same page again, then analyze the HTML code and again use HttpRequest to fetch the referenced files of interest.

Hi,
I am new to C#, I have a doubt please tell me the answer.
I have a form1. In that I am retrieving student information(studentgroup, studentname, admintionnumber). Now
<br />
<br />
namespace student_information<br />
{<br />
public partial class Form1 : Form <br />
{<br />
<br />
string m_stname;<br />
string m_sgroup;<br />
int m_iadminnum; <br />
<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
}<br />
<br />
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
m_stname = this.textBox1.Text;<br />
m_iadminnum = int.Parse(this.textBox2.Text);<br />
m_sgroup = this.comboBox1.SelectedItem.ToString();<br />
<br />
<br />
Form1 f1 = new Form1();<br />
<br />
f1.m_iadminnum = m_iadminnum;<br />
f1.m_sgroup = m_sgroup;<br />
f1.m_stname = m_stname;<br />
<br />
<br />
}<br />
<br />
}<br />
<br />
}<br />
In the above code what i did is i am receiving information from form1,
Now that information in f1(object). Can any one tell what is the procedure for store this data into a file.
Also please tell me the procedure for retrieving object information from the same file.
Thanx in advance......
