You can't use VS 2003 with .Net 2.0. Either purchase an 2005 version of VS or just use one of the freely available Express editions. They can be installed side by side and not interfere with each other.

Don't try to mix them. You will fail.

i want to show in a tree XML file, the problem is that i want the tree to have only the element name inner text, how can i do it, i always have a problem with the function:

<folders>
<folder>
<name>80
<folder>
<name>Madona
<media>
<file>C:\songs\80\Madona\Like a vergin.mp3
<file>C:\songs\80\Madona\papa.mp3

<folder>
<name>Madona
<media>
<file>C:\songs\80\Madona\Like a vergin.mp3
<file>C:\songs\80\Madona\papa.mp3

<folder>
<name>90
<folder>
<name>Metallica
<media>
<file>C:\songs\90\metallica\blackend.mp3
<file>C:\songs\90\metallica\unforgiven.mp3

what do you say Smile | :)

The tree should look like this:
80
madona
madona
90
metallica

Thanks Smile | :)

Your XML isn't displayed properly. Replace the < and > tags with [ ] and repost. People here understand that [ and ] map to < and > respectively. You might then get a quicker answer.

The website http://www.codeproject.com/csharp/englishparsing.asp[^] states that you can get the .bin files from http://cvs.sourceforge.net/viewcvs.py/opennlp/models[^] but cannot get there. How else can I obtain those files to get the application to work?

Thanks.

Is there a way to run an app as a system-user on the compact framework?

I need to do some stuff with the certificate store, and I keep getting no-permission errors..

Help would be much appreciated Smile | :)

HELP! Processor at 100%

I have a datagrid with a dataset table as it's datasource and a tree with a copy of the original dataset table as it's datasource. The datagrid dataset can be changed, but the tree needs to stay constant.

This is for a biology app. After I add nodes for each Family\Genus\Species to the tree I want to go back through it and add a (number) after each node to designate how many collections are under each node.

This works fine on faster processors but not on slower as the processors hit 100% and take up to 8 minutes to run. It takes 8 seconds when it doesn't hit 100%.

Here is the code that adds the (number) after each node:

public void AddCollectionsToNodes()
{
this.collectionTree.SuspendLayout();
this.CollectionsDataGrid.SuspendLayout();

string oldFilter = "";
if(dsCollections.Tables[0].DefaultView.RowFilter != null)
{
oldFilter = dsCollections.Tables[0].DefaultView.RowFilter;
}
try
{
foreach(TreeNode all in this.collectionTree.Nodes)
{
foreach(TreeNode family in all.Nodes)
{
string filter = "";
if(oldFilter.Trim().Length > 0)
{
filter = oldFilter + " AND Family_Name='" + family.Text + "'";
}
else
{
filter = "Family_Name='" + family.Text + "'";
}
dsCollections.Tables[0].DefaultView.RowFilter = filter;
int rowCount = dsCollections.Tables[0].DefaultView.Count;
family.Text += " (" + rowCount + ")";
if(rowCount > 0)
{
foreach(TreeNode genus in family.Nodes)
{
int count = 0;
for(int i = 0; i < rowCount; i++)
if(dsCollections.Tables[0].DefaultView[i]["Genus_Name"].ToString().Trim() == genus.Text.Trim())
count++;
genus.Text += " (" + count + ")";
if(count > 0)
{
foreach(TreeNode species in genus.Nodes)
{
count = 0;
for(int i = 0; i < rowCount; i++)
if(dsCollections.Tables[0].DefaultView[i]["Specific_Epithet"].ToString().Trim() == species.Text.Trim())
count++;
species.Text += " (" + count + ")";
if(count > 0)
{
foreach(TreeNode infra in species.Nodes)
{
count = 0;
for(int i = 0; i < rowCount; i++)
if(dsCollections.Tables[0].DefaultView[i]["Infra_Epithet"].ToString().Trim() == infra.Text.Trim())
count++;
infra.Text += " (" + count + ")";
}
}
}
}
}
}
}
}
}
catch ( System.Exception e)
{
MessageBox.Show (String.Format ("Error: {0}", e.Message), "Add Number of Collections to Family Nodes");
}

dsCollections.Tables[0].DefaultView.RowFilter = oldFilter;

this.collectionTree.ResumeLayout();
this.CollectionsDataGrid.ResumeLayout();
this.collectionTree.Nodes[0].Expand();
}

Thanks for any ideas!

Look at the number of nested for loops you have and its no wonder it pegs the processor.

If you need to get the number of child nodes use node.Nodes.Count.

Problem is, (number) is not the number of child nodes, it's the number of collections that will be seen in the datagrid for that particular parent/child/child node.

Can you return the number of these collections from the database? Get a second resultset from your query and use it to populate the treeview.

Populate the treenode by issuing a select that returns COUNT and put that number in the node.

What is the best way to return more than one value back from a method?

I have a method that I'm calling that I want to return back some data, a primary key, and the datetime stamp. I was thinking of returning a struct back, but was wondering if there was a better way?

Tom

A struct or some out variables on the signature, depending on if the struct makes any sort of sense beyond being a way to return the values.

You can also use "out" paramaters, which let you pass information back as a write only variable.

private string ReturnStuff(out var1, out var2)
{
var1=something;
var2=something;
return primaryKey;
}

Note these are Write-Only variables.

Indeed. Asking for answers without try does not benefit students at a long run. It looks like a side effect of forum.

Hello guys, Jun, Christian Smile | :)

Well, why don't we help the newbies with code snippets? This would encourage them, and give them a head start, wouldn't it?

I mean.. Is it "cheating" if we help them with a line or two, just as an assistance in their projects? I don't endorse it as a habit, yet I think they sometimes deserve more help than mere general guidance don't you agree? Smile | :)

Yeah right!!

If you're a student, get used to the fact that nobody is going to do your job for you. Nobody.

If you are already in the industry, why have you not figured that out yet?!?!?!?!?! Poke tongue | ;-P

Good luck. The clock is ticking...

Dataset copy

hi,

I create a dataset and fill it with access database. everything is fine, I can see the data in the binded grid control. but i have an exception when I do the copy operation. the exception says, the dataset can not pass the constrains (non null, foreign key...).

I think I can not create the first dataset if the data is wrong?

does anyone have idea about this?

Thanks a lot!

DataTable has two methods, BeginLoadData and EndLoadData, which can be used when copying data into the table to prevent constraints from being enforced temporarily. Try using those when copying the data.

I am coding a interest calculator in C# using Visual Studio 2005 Express edition and I keep on getting the following error: "CalcBalance does not exist in the current context".

Convert.ToInt32(TextBox3.Text),
Convert.ToInt16(DropDownList1.SelectedItem.Value)).ToString();
}

private string CalculateBalance(int Principal, double Rate, int Years, int Period)
{
double result;
double NumToBeRaised = (1 + Rate / Period);
result = Principal * System.Math.Pow(NumToBeRaised, (Years * Period));
return (result.ToString("C"));
