Hi,

I'm trying to find the existence of a child node in Treeview control. I used the following find(), Contains(), ContainsKey() methods.

1. TreeNode[] ad= treeView2.Nodes.Find("child2",true);
2. bool res= treeView2.Nodes[0].Nodes.Contains(selNode);
3. res = treeView2.Nodes[0].Nodes.ContainsKey("child2");

None of the above is giving result. Please let me know how to find a child node in a treeview control.
Thanks in advance.

what are you searching for and is it in the base level only?

the Find method should work fine, "child2" should be the key of the node to find, i.e. the Name property, change false to true if you want to search deeper than the base level.

what results are you getting from you find function?

Try the following code for the same:

For Each LeftMenuNode As TreeNode In LeftMenu.Nodes ' LeftMenuNode will give you Nodes in TreeView
For Each LeftChildNode As TreeNode In LeftMenuNode.ChildNodes 'LeftChildNode will give u childnodes if any
If LeftChildNode.Text <> "Child Nodes" Then
LeftChildNode.NavigateUrl = "#"
End If
Next
Next

Ive never seen a more non-sense programming language lol

Anyway after translation it is a good suggestion, but from what i gather this will only search levels 0 and 1 of the treeview. No?

infact your code s k to find the child the treeview control
what more u have to do is to select that child node.
[code]
if (treV.Nodes.Find("child",true).Length>0)
{
treV.Focus();
treV.SelectedNode=treV.Nodes.Find("child",true)[0];
treV.SelectedNode.EnsureVisible();
}
[/code]

create the maximum number of different textboxes you need, then assign them a number each i.e.

TBLine1 = 0
TBLine2 = 1
TBCity = 2
TBRegion = 3
TBPostcode = 4
TBCountry = 5

Then in your database you have a list of countries and also a column with the order the address should be displayed split with a non numeric character, i.e.

UK 0;1;2;3;4;5

USA 2;3;4;5

Then you can parse the column and dynamically set the location of the fields based on the ordering

Auto text match and replace

Hi,

I need to create a simple application where a user types in an abbreviation of a word and this is automatically changed into the full word. The text can be entered in any application e.g. MS Word, MS Excel, Notepad, E-mail, Blog, etc.

A simple example:

Use enters.. tc<space>mw.
System recognizes a space, comma or any other punctuation and replaces the text to.. take care Matthew White.

tc -> take care
<space> triggers the previous action
mw -> Matthew White
fullstop triggers the previous action

Basically, the application matches the entered text to a dictionary (edited by user) and replaces the word with the meaning. Also the program can be running in the task bar allowing the user to disable the feature.

Well, what you are descibing does not fit this category, at least to my mind, but if you think its a simple application go ahead and create it - I would be interested in seeing the finished product.

Change date format setting of {Regional and Language Options}

As I said, its far from simple and to be honest I have no idea how you are going to do it - you need to hook into ANY app that has a text area and monitor key presses.

All I can say is good luck.

Problem in DataSet

hi.

Please see the following code.

HistoryData is also a dataset..

string strExpression = "Date >= '1/2/2009' And Date <= 2/2/2009"

Dataset dsData =  HistoryData;
DataSet dsNew = new DataSet();

DataTable dt = dsData.Tables[0];  

DataRow dr = dt.Select(strExpression);

in the above code it gives the filtered rows into dr.

but i need to apply the select command to dataset and copy the filtered data into new dataset.

Please help me..

Hi,

first of all the statement:
DataRow dr = dt.Select(strExpression);
will return the array of rows not a single row. So it will be
DataRow[] dr = dt.Select(strExpression);

After this you can traverse in the DataRow using Foreach and then can add the same in the new table having same columns(structure)

foreach (DataRow dr in dt.Select(strExpression))
{
DataRow drRow = newtable.NewRow(); // newtable having same structure as of the main table dt
drRow["Column1"] = dr["Column1"].ToString();
drRow["Column2"] = dr["Column2"].ToString();
drRow["Column3"] = dr["Column3"].ToString();
...
drRow["Columnn"] = dr["Columnn"].ToString();
drRow.Rows.Add(drRow);
newtable.AcceptChanges();
}

This way you can get a new table having required rows.

I think better to use DataView to create new table instead looping through all filtered rows and add them to datatable
i am suggesting following
[code]
DataView dva1=new DataView(dataTable or dataSet);
DataTable dt=dva1.toTable(filterString);
[/code]
