I have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?

View 1 RepliesI need to work with multiline textboxes. I am currently developing a web application that was started by someone else. The only problem I have is the text in my multiline textboxes is going to the next line before it needs to. I have played around with settings, removed the textboxes and added them back, and I am still having the same problem. When typing in the textboxes, the text moves to the next line after pressing the space bar.

I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the
VB.NET
Public Structure valTxtBox
Public nome As String
Public texto As String
End Structure
[Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.

I have a multiline textbox that while a file is read in some data is echo'ed out onto the textbox. Is is possible to programatically scroll the object down to the bottom?

View 5 RepliesI'm trying to make a textbox at runtime, Dim t as Control
t = New Textbox
t.Multiline = True
t.Size = New Size(300,120)
Form1.Controls.Add(t)
I found out that you can only size a textbox when Multiline is set true. And that's the problem. When I use t.Mutiline = true I get the error " 'multiline' is not a member of 'system.windows.forms.control' "
I've searched the internet for hours without result.
