No, unfortunately not. I don't think that glutBitmapString has the ability to render text at any angle. I've looked for an alternative font library, but I either can't find a suitable one, or they are not created for use in C#
Edit: I've also tried using the glutStrokeString function, but I cant get this to render anything at all.

hi
i want to get position of my datarow in dataset, How to do that ??
i am using vC# 2005
thanks

Well, a DataSet doesn't contain rows directly. Rather, it contains DataTables, which then contain rows. To find a row in a table in a dataset, you need to iterate over all the DataTable objectss, then look for the row in each table. Something like this:
int GetIndexOfRow(DataSet dataSet, DataRow row)
{
foreach(DataTable table in dataSet.Tables)
{
int index = table.Rows.IndexOf(row);
if(index != -1)
{
return index;
}
}
return -1;
}

I am displaying blocks of text in a datagridview control. The column is setup to not wrap or size. The first x characters are shown and then truncated. Since the column type is string, the datagridview shows the entire cell contents in a tooltip. Is there a way to control the font of this default behavior? I just need to increase the font size from what looks to be 10pt to 12pt or 14pt.
Any information would be greatly appreciated.

Did you find the solution....? I am also stuck in the same problem.

I downloaded the 'Building a Data Access Layer - The Demo Application' by Damon Armstrong. I want to use the DataServiceBase class that he built in another application. I do not want to use the PersonDataService that he has in the same Namespace. To make a long story short, I copied the class that I want to a new C# Class Library. There is only one problem, it won't compile. I get the following error:
The name 'ConfigurationManager' does not exist in the current context C:\HAA_C_Library\DataServiceBase\DataServiceBase.cs
Here is the method that causes the error:
protected static string GetConnectionString()
{
return ConfigurationManager.ConnectionStrings["DB"].ConnectionString;
}
I have the following before the start of the class:
using System.Configuration;
When I go to the Object Browser, it shows ConfigurationManager as a class within System.Configuration. Yet, when I try to use it; it is not there. When I go to the original code that I downloaded, it behaves as desired.
What is happening here? I've looked at everything I know to look at and can't see any difference between the original code and mine. But one works and one doesn't.
Thanks in advance,
Mary

Well, after trying almost everything. I got it to work. I added System.Configuration to the References section. Now all is fine. Evidently, it was not using the correct library.
|
|
|
|
|
No, you were using the correct library you just hadn't told the compiler to link it in, so although it was importing the System.Configuration namespace it couldn't actually find it.

i wanna to know how can i generate an algorithm by using DNA computing to solve A/B problem? is it NP complete?
SUMA
|
|
|
|

bool isA = false;
bool isB = false;
foreach (chromosome c in theCell)
foreach (gene g in c)
{
if (g == KnownGenes.BloodTypes.A)
isA = true;
if (g == KnownGenes.BloodTypes.B)
isB = true;
}
if (isA && isB)
printf("type AB");
else if (isA)
printf("type A");
else if ( isB)
printf("type B");
else printf("type O");

Rules of thumb should not be taken for the whole hand.

thanks alot for reply, is there a way to proof that a\b is a NP complete or not?? using hamitolian path for example?is their such algorithm for that??

i didnt mean that,, i wanna to know if there any resources of what i need couse i searched but i didnt find any good result, & if u familiar of these kind of problem u know that it is just the first step

Harta hr = this.ParentForm;
hr.OnPaint1();
this code raises the folowing error
Error 1 Cannot implicitly convert type 'System.Windows.Forms.Form' to 'THE_PROJECT.Harta'. An explicit conversion exists (are you missing a cast?) C:\Documents and Settings\Razvan\My Documents\Visual Studio 2005\Projects\THE PROJECT v2\THE PROJECT v2\Elemente.cs 48 23 THE PROJECT v2
i knew it was imposible for that to work but i need to call that method from the child form. Can somebody help me?

The method that Pete mentions is valid. However, I would suggest you look at having the child form raise an event that the parent form subscribes to.
public class MainForm : Form<br />
{<br />
public void CreateChild()<br />
{<br />
ChildForm cForm = new ChildForm();<br />
cForm.ParentForm = this;<br />
cForm.MyOnPaint += new EventHandler(OnPaint1);<br />
<br />
cForm.Show(); <br />
}<br />
<br />
protected override void OnPaint1(object sender, EventArgs e)<br />
{<br />
}<br />
}<br />
<br />
public class ChildForm : Form<br />
{<br />
public event EventHandler MyEvent;<br />
<br />
protected override void OnMyEvent(object sender, EventArgs e)<br />
{<br />
if (MyEvent != null)<br />
MyEvent(sender, e);<br />
}<br />
}
Please forgive any typos as I wrote the above code on-the-fly. So, in the child form when something happens that you want to communicate back the event you just call OnMyEvent from within the ChildForm. The nice thing about this is that it promotes loose coupling, because the ChildForm doesn't know if it's parent is MainForm or SomeOtherForm. You can take it a step further by making the event part of an interface that ChildForm implements. In that way you decouple the child from the parent as well.

Have you checked IsClosed()?

Hi everyone!
Please help me with following questions:
1- How can we add nodes in treeView using following context menu:
Before Node (at same Level)
After Node (at same Level)
Child Node
2- How can we disable particular contextMenuItem? For example if root node is selected "Before Node" will be disable. Where should I put "meuItem.enable = fasle;" line in the code. I have used "treeView_AfterSelect" event for disabling but it doesn't work fine with right click.
Please guide me by an example and please tell me if any sample on code project regarding treeView.
Thank You.

Go add a new TreeNode at the same level as a given TreeNode you will need to look at the current TreeNode's parent and add your new node to the parents Nodes collection using the Insert method of the TreeNodeCollection.
A rough example (not tested):
.
.
.
int currentIndex = CurrentTreeNode.Parent.Nodes.IndexOf(CurrentTreeNode);
.
.
.
CurrentTreeNode.Parent.Nodes.Insert(NewNode,currentIndex);
.
.
.
CurrentTreeNode.Parent.Nodes.Insert(NewNode,currentIndex+1);
.
.
.
Note that you should check that the current node isn't the root (parent == null).
To add a child you simply add a new node to the current node using CurrentTreeNode.Add(NewNode)
To disable the menu items you might want to do it on the context menus Popup event.

How can I set the currentTreeNode equal to Selected Node.
I want to add before and after the selected node.
Thank you.

You need to hook in to the AfterSelect event and then test the value of e.Node.Level to determine what level in the tree control the selected node is located. Based on this value you can enable/disable different menu items. To do this with mouse clicks, you need to hook in to the NodeMouseClick event. You can test using something like e.Node.IsSelected && e.Button == MouseButtons.Right
In your event handlers, you will need to use the value of e.Node to determine which node you need to interact with to add the new TreeNode object.
