C# - Getting A Certain Node Using DataSet?
Mar 29, 2010
I have the following XML
<xml>
<ObsCont xCampo="field1">
<xTexto>example1</xTexto>
</ObsCont>
[code]....
Is there a way to get the content of "xTexto" inside the ObsCont that has "field2" value for the attribute xCampo using DataSet?It would be desireable to have a single liner like the following:
DataSet ds = new DataSet();
ds.ReadXml(StrArquivoProc);
ds.Tables["xml"].Rows[0]["field"].ToString();
//field == "information"
If I use the same method I'm not specifying that I want the one with the desired attribute.

i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.
vb
Dim reader As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath() & "ConfigDevs.txt")
Dim strs() As String = Split(reader, Environment.NewLine)
For Each s As String In strs
[code]....
Thats what i have so far, how can i set it so 'Dim parentNode As TreeNode = ' points at the 'Developer' node?

I have a tree view in my project with a parent node and with theoretically speaking infinite child nodes.
Now I want to delete the last child node from the tree view when the user presses a certain button. I thought I could do this trick with this code:
Private Sub Bundo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Bundo.Click
Try

Basically, it refuses to find the node when the root node contains an attribute.
[code]...
When I do xml.SelectNodes("DataSet") with the xmlns in the root tag, it finds no nodes. If I remove the xmlns attribute, it works fine.How can I make it work while leaving the attribute?

Finding the level of the particular xml using a node value in .Net Experts ! This is my sample Xml.This is a tree structure and T->T.1,T.2->T.2.2,TA->TA.1 - this is the tree strucutre. I know the value of tag . ie 1232,1343.. etc.Using this ID how can I find that 1343 is coming under 1232. or 1490 is under 1090 which is again under 1232.Expected output : if i pass 1490 then I need to know 1490,1090,1232 etc (from that nodeto the top node).I am using .net 2.0
<Abc>
<A>
<Name>T</Name>
<Id>1232</Id>

I need to add a node which should be next to the selected node. Not as child node. It should be in same level but next to the selected node. Provide the sample in VB.net with default treeview control.

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.

I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all.

I have multiple datasets that I would like to combine into one. There is a common ID field that can be associated to each row. Calling Merge on the dataset will add additional rows to the dataset, but I would like to combine the additional columns. There are too many fields to do this in one query and therefore would make it unmanageable. Each individual query would be able to handle ordering to ensure the data is placed in the correct row.
For Example lets say I have two queries resulting in two datasets:
SELECT ID, colA, colB
SELECT colC, colD
The resulting dataset would look like
ID colA colB colC colD
1 a b c d
2 e f g h

ok, I've finally got my test database issues sorted out, however now I need to actually modify my existing report to add the two new fields from my test database. I have made a copy of the report so that I am not modifying the original. I have deleted the two old fields and now want to add my two new fields in there. In the Field explorer window, I see an object called "dataset1" and when I expand it, it is using a view that includes fields from the table that I added my two new fields to.
The problem I see here is that I have gone in and modified the view to include these two new fields in my test database - but again, they are not showing up as selectable fields here. I am just assuming that "dataset1" is somehow pointing to the live database again and that I need to change the datasource location.In my solution explorer, I see an object called "dataset1.xsd" but the properties of that do not tell me much about where it is actually pointing to...

I have some concern about designing Datasets. I was told that it would be good to have a dataset for each table for maintenance purpose. Because frequent change in database tables is expected, having one dataset including every tables would be pain to make the corresponding change in the application.
Q. is it good approach to have a dataset for each table ( I would end up having 30~40 datasets for each db table using Stored procedure) ?
I have a separate project for commonly used datasets. each project include "dataset project" as a reference, and use it by including needed dataset into Forms, classes, etc.
Q. Does this approach makes the whole system to be slower? If I have a set of datasets as a separate project, it would be beneficial, since It will be easier to make a change (I only need to make modification in one place)
