my application contain three forms:
frmMain(mdiContainer)
frmEditable
frmTools
private void frmEditable_MouseDown(object sender, MouseEventArgs e)
{
choice1Enable = true;
if (choice1Enable)
{
Generating(0, e.X, e.Y, 20, 20);
}
}
i want to capture this events using delegate..it is located in frmEditAble form.
actually i want that when a user click on frmTools's Rectangle label. it should be displayed a rectangle on frmEditable thorugh delegate..
how can i do this
hghghgh

I'm not sure I entirely understand your question, is this what you are looking for?
First, you need to create an EventArgs class that will notify the listeners which rectangle should be genereated:
public class NewRectangleEventArgs : EventArgs
{
public int ID;
public int X;
public int Y;
public int Width;
public int Height;
public NewRectangleEventArgs(int ID, int X, int Y, int Width, int Height)
{
this.ID = ID;
this.X = X;
this.Y = Y;
this.Width = Width;
this.Height = Height;
}
}
Next, you need to create an event in your for class that others can register to:
public EventHandler<NewRectangleEventArgs> OnNewRectangle;
Now, other classes can register the event when they have a handle to your form:
form.OnNewRectangle += new EventHandler<NewRectangleEventArgs>(NewRectangleEventHandler);
With NewRectangleEventHandler being a method like:
public void NewRectangleEventHandler(object sender, NewRectangleEventArgs args)
{
}
Finally, your form needs to raise the event whenever a new rectangle should be generated:
if(OnNewRectangle != null)
OnNewRectangle(this, new NewRectangleEventArgs(0, e.X, e.Y, 20, 20));
Hope this helps

hi
i have problem with this code
objCommand.Parameters["@nopersoneli"].Value = Int32.Parse(vpost.txtNoPersoneli.Text);
:error
Input string was not in a correct format
why?
please help me
|
|
|
|
|
Most likely you have illegal characters in vpost.txtNoPersoneli.Text
The need to optimize rises from a bad design
|
|
|
|
|
What is the type of objCommand?
What is your vpost.txtNoPersonali.Text?
|
|
|
|
|
txtNoPersoneli forexample=45
|
|
|
|
|
What is objCommand? It's possible that your objCommand.Parameters["@nopersoneli"].Value gets string and you get it an integer variable.
and what is this "@" for?
|
|
|
|
|
Most likely you have some type of invalid character in vpost.txtNoPersoneli.Text...

Hi.
Please write your snippet code here.

try
objCommand.Parameters.add["@nopersoneli"].Value = convert.toint32(txtNoPersoneli.Text);

// write the expected and calculated minimax values to the console
Console.WriteLine("Expected minimax value is 5");
Console.WriteLine("Calculated minimax value of the tree " + tree.Minimax(true));
//Console.Write(tree.children.first);

And what is your question after all?
|
|
|
|
|
My question after all is about how to add a code with the variable that holds minimax value of the node, the node having a variable that holds the board position bearing in mind that the value of this valuable can be an array of length 9 which makes values X and O (or 1 and -1 talking of integers) leading to generating a tree automatically by computing successor states for the board positions represented by a particular code, starting with the empty board for the root node, recursively computing successors until terminal nodes reached.

Hi,
First of all, Please let me know if I am posting in the wrong forum.
I am tryingto access a class written in c# which has an array of classes. The class code is:
public class ClientData
{
private ClientDataDetail benchmark;
private ClientData[] buckets;
private ClientDataDetail portfolio;
public ClientDataDetail BenchMark
{
get{ return benchmark;}
set{ benchmark = value;}
}
public ClientData[] Buckets
{
get{ return buckets;}
set{ buckets = value;}
}
public ClientDataDetail Portfolio
{
get{ return portfolio;}
set{ portfolio = value;}
}
}
When I try to access this class in VBA as follows:
Dim clntData As ClientData
Set clntData = dispData.GetClientData()
//This is the line where I get the error: "Wrong Number of arguments or Invalid property assignment"
Dim anotherClntData As ClientData
<b> anotherClntData = clntData.Buckets(0)</b>
The same code (i.e. accessing the internal array of ClientData class via the indexer) works perfectly fine in c#.
Any pointers. Do I need to use an arraylist in place of array of classes?

Your C# Buckets function gets or sets the whole buckets array (gets or sets ClientData[]) but you want to get one element from Buckets (ClientData)

Hi Pedram, Thanks for replying.
I do undertsand your reply.But then Please let me understand how come the same code functions correctly in c#? (If I understand what makes it work in C# maybe I could implement the same thing in VBA) Code sample below:
DisplayData cd = new DisplayData();
ClientData clntdata = new ClientData();
clntdata = cd.GetClientData();
ClientData data1 = new ClientData();
data1 = clntdata.Buckets[0];
Thanks,
Neeraj

I think this works:
DisplayData cd = new DisplayData();
ClientData clntdata = new ClientData();
clntdata = cd.GetClientData();
ClientData data1 = new ClientData();
cd.Buckets = new ClientData[100];
data1 = clntdata.Buckets[0];

Hi Pedram,
Sorry for the late reply. Had left office the other day and I didn't have net access at home.
You are right. I am setting clientData.Buckets to some meaningful value. That was inside the function GetClientData().
What I am asking is that even after doing this,
ClientData data1 = new ClientData();
cd.Buckets = new ClientData[100];
// clndata.Buckets[0] = //Something usefull
data1 = clntdata.Buckets[0];
The last line gives me error. But the other two classes i. e. Protfolio and BEnchmark are accessible in VBA.
If I have an array of classes (private ClientData[] buckets;) in the class (ClientData) itself, can we not access it like c#? If not how can we modify the code to access it?
Thanks again for your time.

I saw your post right now so I'm sorry too.

Did you uncomment line 3?
If not, it's like this:
int a;
int b = a;
Did you understand? You have to set a value for your variable before you can get it.
If yes and you uncomment line 3, I really don't know what is happening to your application, and unfortunately I have no more idea 
What's your error message?

I want to set two find options : "MachCase" and "WholeWord"
this code works correctly :
richTextBox1.Find(StrSearch, RichTextBoxFinds.MatchCase);
but this code doesn`t work; It has compiler Error :
richTextBox1.Find(StrSearch, RichTextBoxFinds.MatchCase, RichTextBoxFinds.WholeWord);
How should I write this code to set either RichTextBoxFinds.MatchCase, RichTextBoxFinds.WholeWord
Hello Friends

If you noticed, RichTextBox.Find method has two arguments: string str, RichTextBoxFinds option.
So you have error.
You should ask your user which option he/she wants. MatchCase OR WholeWord
|
|
|
|

I know. But May be an User have either "MachCase" and "WholeWord" even more like "search Foreward or Backward".
This ability is also in Standard application like Microsoft Word or Visual Studio
Hello Friends
|
|
|
|
|
Well simply search your text with MatchCase if Find can't find anything (returns -1) search for WholeWord.
