Sounds like you're making progress
You should use Invoke not BeginInvoke in AddPicture if you're using a thread. Otherwise, the thread will not block and will loop round adding all the images without waiting for each image to be added.
For the interrupt method, just call CancelAsync once, and then handle the RunWorkerCompleted event.

Is there a BinarySearch for IList<T> - or a similar generic BinarySearch?
Couldn't find any besides the (non-generic) Array.BinarySearch

There is a generic version of Array.BinarySearch . You can use that to search in IList(T) . Assume you have sorted strings in IList(T) .
int index = Array.BinarySearch<string>(list.ToArray<string>(), "SearchString"); list.ToArray<string>() is an extension method. If you are on .NET 2.0, you won't see this.
Hope it helps

if (list == null) throw new ArgumentNullException("list");
if (comp == null) throw new ArgumentNullException("comp");
if (list.Count == 0)
return -1;
return BinarySearch(list, item, comp, 0, list.Count - 1);
}
private static int BinarySearch<T>(IList<T> list, T item,
Comparison<T> comprasion, int start, int end)
{
while (true) {
int i = (end + start) / 2;
int cmp = comprasion(item, list[i]);
if (cmp == 0)
return i;
else if (cmp > 0) {
if (i == end)
return -1;
start = i + 1;
}
else {
if (i == start)
return -1;
end = i - 1;
}
}
}
} Hope this helps .

How many weeks (months?) have you been trying to call 1 method for now?

Whenever I try to encrypt or hide my strings my program immediately crashes when I double click the .exe. Does anyone have a clue of why this may be happening. I'm using 9Rays.net Obfuscation.
Thanks,
Buckley.

It might be another setting in the 9rays software causing the crash. Have you asked 9Rays about it?

I draw the string("ABCDEFGH")or Square in panel using c#.I want to rotate the shape
in any angles.Please help me how to find the Center point and rotate the shape.
Note: I used DrawLine() method to draw shapes

Create a custom panel control and you'll have to do your rotational transforms in the Paint method of your custom panel control. Do an article search, there are many on how to do this.

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?
|
|
|
|
