SqlDataAdapter adapter = new SqlDataAdapter(yourQuery, conn);
DataSet ds = new DataSet();
DataTable dt = new DataTable("tablename");
adapter.Fill(dt);
ds.Tables.Add(dt);
ds.WriteXml("C:\text.xml");
Then On your crystal report Database Fields:
change your dataset with "text.xml"
If U have finish it, then create a dataset with your query, then change the code like this:
SqlDataAdapter adapter = new SqlDataAdapter(yourQuery, conn);
DataSet ds = new DataSet("YourDataSet");
DataTable dt = new DataTable("tablename");
adapter.Fill(dt);
ds.Tables.Add(dt);
ReportDocument rd = new ReportDocument();
rd.SetDataSource = ds;
crystalReportViewer1.ReportSource = rd;

ds.WriteXml("C:\text.xml");
-- \t is the character code for a tab. You need to escape your backslashes by... using another backslash.
ds.WriteXml("C:\\text.xml");

Hello Edwin,
One of my friend had told me that this issue can be resolved through SELECT EXPERT. Do you had any idea about this.

Hi there .
Look my friend you set you ReportViewer data source it's wrong . you must create new instance of your CrystalReport.rpt file . for example i have an report file named report.rpt .
// Create new instance of your CrystalReport File
Report _Report = new Report();
// Set Report data source ,no your viewer .
_Report.SetDataSource(Your_DataSource);
// Finally set your report viewer report source to your Report file .
crystalReportViewer1.ReportSource = _Report;

Hello everyone,
Is there anyone that I can know there was a Mouse Double Click in the MainForm_MouseDown? I currently can detect if there has been a Left or a Right click but I would like to be able to check for Double Click.
if (e.Button == MouseButtons.Left)<br />
{<br />
MessageBox.Show("You have just clicked on " + e.Button + " button.");<br />
MessageBox.Show("X: " + e.X + " -- Y: " + e.Y); <br />
}<br />
if (e.Button == MouseButtons.Right)<br />
{<br />
MessageBox.Show("You have just clicked on " + e.Button + " button.");<br />
MessageBox.Show("X: " + e.X + " -- Y: " + e.Y);<br />
}
Thank you very much and have a great day.

Hello,
I don't think that it's possible in MouseDown, as MouseDown is fired bevore Click and Double Click.
But MouseUp is fired after Click and DoubleClick.
So this would work:
private bool FlagDoubleClick = false;
protected override void OnDoubleClick(EventArgs e)
{
FlagDoubleClick = true;
base.OnDoubleClick (e);
}
protected override void OnMouseUp(MouseEventArgs e)
{
if(FlagDoubleClick)
{
FlagDoubleClick= false;
}
base.OnMouseUp (e);
}
All the best,
Martin

Hi,
MouseDown event offers MouseDownEventArgs parameter
its Clicks member contains what you need:
on a double click, the event fires twice, once with Clicks=1, once Clicks=2

Hello Luc,
I just tested it and saw that it works.
But I don't understand why.
When is the Clicks property reseted?
And isn't a Click only a Click if the MouseUp is excecuted?
I'm sure you will clear my confusion!
Thanks for your time!
-- modified at 5:56 Monday 30th July, 2007
Just did additional tests, and now I think I understand it.
Looks like the DoubleClick is fired only by the correct MouseDown delta time, no second MouseUp needed for the validation.
But it get's fired only after MouseUp is excecuted.
I'm not sure if this behaviour is very logic, but who said that programming has to be logic at all!
All the best,
Martin

Hi Martin,
Martin# wrote: I just tested it and saw that it works
A click consists of a down followed by an up (both keyboard and mouse)
To count clicks, you could wait until you get a click, then increment counter;
or you could simply count physical downs (cant have two physcial downs without an
up in beteen !)
So you may argue that the member name should have been Count instead of Clicks,
but it is no miracle they can make it work.
And you would be right if you don't like MSDN saying "MouseEventArgs.Clicks gets
the number of times the mouse button was pressed and released"

Hello Luc,
Luc Pattyn wrote: So you may argue that the member name should have been Count instead of Clicks
Would be better!
Specially when you see a scenario, where you:
Make the double MouseDown fast enough for the DoubleClick (so in MouseDown, you get e.Clicks == 2), and then Move the Mouse over an other Control bevor you release the Mouse.
In this case you would assume the DoubleClick is comming because of MouseDown, but it will never get fired.
All the best,
Martin

Martin# wrote: then Move the Mouse over an other Control
that is why one should use KeyPress and MouseClicked as much as possible,
and only use KeyDown and MouseDown if something really needs to be done
as soon as the user's action starts.

Hello,
I'm trying to make an application so that I can display an XML document such that it doesnt show the text in the tag names of the XML document. It should show the text in those tags rather than tag names. e,g
<my_tag>This is my Tag
Then it should display 'This is my tag' instead of my_tag. Please tell me how I can do that. The problem is further increased as I want to provide some filtering capability on the basis of this text prior to populating the treeView.
Any help would be highly appreciated.
Thanks

I want to develop an input method (using visual studio 2005 and c#) for my mother_language .
(when inputing a character it will lists the words which begin with the character).
anybody can tell me what should I do? please help me!

I believe that it's possible to build a list of words and set them up to offer auto complete, either in a textbox, or a list box ( not sure of hte details ). If not, you need a list of words, and you need to show a filtered list as someone types.

Sounds like you are trying to implement some sort of auto-complete? Correct me, if I am wrong

I am not sure this is a great idea.
Unless your native language has a lot of characters, there may be hundreds or
even thousands of words starting with the same character, so showing all these
in a list will take quite some time, and may not be appreciated by the user at all...

Do you mean how to create connection to sql server or what?
If you want to create connection to sql server 2005 Express :
Step 1:
In you app.config add this code
<connectionStrings>
<add name="CONNECT"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=YourDatabase;Integrated Security=True;"
providerName="System.Data.SqlClient" />
</connectionStrings>
Step 2:
add reference to your main code
using System.Data;
using System.Data.SqlClient;
add this to your main code
string connectionString;
connectionString = ConfigurationManager.ConnectionStrings["CONNECT"].ConnectionString;
SqlConnection conn = new SqlConnection(connectionString);
then if you want to open connection to your database :
conn.Open();
if you want to close connection :
conn.Close();
Hope this will help you.
Regard,
Edwin

Actually, the connection string i have done it but still i have problem.
let me explain what exactly happen in my application..
- my system is created in the c# express edition and for database is sql server 2005 (express edition)
- the system is in console application...
The idea is like these:
- supposed that my system can retrieve the result that fired by the trigger everytime there is a data inserted. Means that, everytime a data inserted into the table, all the data details would be display on the console application
- for now i have created the trigger but i dont know how to display the result fired by trigger on the console application.
If u can help me or give me idea on this, it would be very helpful.
Thanks in advance
Jac

Oh... Console base application...
Usually I create Windows app. To show my data, I usually use Datagridview.
If I want everytime a data inserted into the table, I just refresh the Datagridview's data source, and it will show the inserted data.
In your case, if you show your data using dataset or xml you just need to declare your data source again... I think it will auto refresh.

Edwin

hem...so do u mean that i dont need the trigger function?...because i dont have any other way to get the real time data inserted in the database since the trigger function fired whenever any transaction made on that particular table.
Before, i have done same thing that only using the dataset but if using the dataset i cant get the latest data (real time) inserted.
