Use XmlSerializer.

using (FileStream fStream = new FileStream("test.xml", FileMode.Create))
{
  XmlSerializer s = new XmlSerializer(typeof(DataSet));
  s.Serialize(fStream, dataSet);
}

You can convert the DataSet to XML and then save the XML file to the web browser by setting Response.ContentType appropriately.

SQL Stored Procedure and Datagrid problem...

swjam7-Dec-06 18:31

I need some help guys. Rest assured I have done some research before posting here. Thanks in advance!

I have a form where I added a datagrid control. Then I dragged a stored procedure in one of my connections to the form. This created a SqlConnection and SqlDataAdapter objects below the form. I then created a DataSet using the Generate Dataset wizard. Once the dataset is created, I associated the datasource of the datagrid control to the dataset's stored procedure. Everything seems fine as I can see the columns of the stored procedure appeared as headers in the datagrid.

Next, I initialized the stored procedures parameter by going to the SqlDataAdapter's SelectCommand property. I clicked the ellipses from Parameters and in SqlParameter Collection Editor, I went to initialize each of the parameter's value.

Finally, under the InitializeComponent() of the constructor, I put the following 2 lines to initialize the datagrid with the dataset of the stored procedure:

sqlConnection1.Open();<br />
sqlDataAdapter1.Fill(dataSet11.dbo_spMyStoredProc);

I then run my little application but then gets a runtime exception that I cannot debug due to
Registered JIT debugger is not available.

My questions are as follows:

1. Without having to debug first as there seems to be a problem with the JIT debugger, what could I have missed/done wrong that results in the runtime exception?

2. Is this the best way to running a stored procedure (with parameters) and displaying its result set in a datagrid control?

3. How do I fix the JIT debugger unavailable so I can debug my CSharp codes? It seems to be caused by corrupted VStudio so is reinstalling the only way to fix this?

Again, thank you very much. Hope to hear from you soon as my deadline is approaching.

cheers!

Is it a Web Application or Windows Application?

Yes, when I write my article, I will cover this approach. It's very nasty, you should never do this. At a minimum, expose properties that get ( for example ) the text of a textbox, but not the textbox itself. This isn't VB, we're supposed to know about OO.

That won't help, it's a different instance to the one that has the data you need

You can pass the right instance of form1 to form2 as a parameter, or, better yet, use delegates to pass data between forms.

hi
yes he is right. u would be able to access information of ur control as creating an object
would create new instance of form1 i just told that declaring a control as public would make that control accessible in another form..But to pass value u need to use delegate to communicate between them.

cheers.

It works. But what if I want the document to be displayed in my window application (rather than opening an external application)?

The obvious solution is a webbrowsercontrol, as that already knows how to show PDFs, and can be added to a form.

Wrapped String Calculation

Hi,

I'm thinking how to do a text wrap calculation for a string by myself. I need to calculate how many lines will a string wrapped to (within a fixed area region). The fixed region is a location and an area for filling the string. I also have to know which part of the string is wrapped to the corresponding line. Could some of you give me some ideas?

e.g.
string txt1 = "AbcdefgHigklmnopqrstuvWxyz. Dear, Hello Hello My Friend...";
if the fill region is limited to the size of "100x400",
what is the good way to calculate how many lines will the txt1 wrapped to?
as we can imagine, txt1 maybe wrapped into 3 lines.
1st line: AbcdefgHigklmnopqrs
2nd line: tuvWxyz. Dear, Hello
3rd line: Hello My Friend...

I'm thinking to use graphics.MeasureString to calculate the width of each character. is it a good way..
I would be appreciated if you can give me some example?
Thanks so much for your help?

MeasureString can be used on the whole string, keep cutting until it fits. Make a string of what's left and start again.

I have to write some C# code to call passport-authenticated web services to verify if some user has the privilege to do that.
This is the first time that I work with passport authentication.
Could anybody please shed some light where I should start or if possible, some sample code that I should follow?

Any help is appreciated.

Thanks,
