Double up the collection. Often I will use both a list and a hash in 1.1. I use the list for iteration and the hash for indexing. If the data is good enough I will keep it in an Array List sorted and Binary Search it.
On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. - Charles Babbage

Since you mentioned that clsLabelCollection inherits from CollectionBase, it should have a Contains and an IndexOf method.
Assuming that both of these are actually implemented in the collection class, you can use them to find a specific clsLabels instance:
clsLabels l = null;
if (m_clsLabelCollection.Contains("value"))
{
int i = m_clsLabelCollection.IndexOf("value");
l = m_clsLabelCollection[i];
}
You can also iterate over the collection (using foreach) and explicitly test to see if the current item is equal to the one you want. When you find the match, break out of the loop.
This would be something like this:
clsLabels l = null;
foreach(clsLabels lbl in m_clsLabelCollection)
{
if (lbl.label == "value")
{
l = lbl;
break;
}
}
I'm assuming that lbl.label is a string field and that you are looking for the label "value".

Hello!
How many GraphicsState can we save. Does it depend on hardware capability? If so, how to get that stack size?
<br />
GraphicsState state1 = g.Save();<br />
GraphicsState state2 = g.Save();<br />
GraphicsState state3 = g.Save();<br />
...<br />
g.Restore(state3);<br />
g.Restore(state2);<br />
g.Restore(state1);<br />]
Thank you.

I dont think you want to call that recursively, its a rather expensive operation. Performace will be terrible before you hit stack overflow.

Dear All,
I am showing some thumbnail pictures in a listbox. Thumbnails have category. Now I want to show tumbnails category wise in ListBOx. So that i can expand or collapse each category to see thumbnails like tree view. Have anybody some idea about it?
|
|
|
|
|
can you use a listview but listbox?
because the listview has SmallImageList property. it can show picture on a item.

You can input anything that matches the ShortTimePattern or LongTimePattern of the current culture.

Hello in keypress event for a text box i want to convert the e.KeyChar into the actual character how do i make it do this?
|
|
|
|
|
Hello Tyrus,
I think two things are possible here.
Inside your keypress event:
1)
if(e.KeyChar == ??)
{
e.Handled = true;
SendKeys.Send("{???}");
}
2)
if(e.KeyChar == ??)
{
e.Handled = true;
textbox.Text.Insert....
}
All the best,
Martin

hi id like to prevent people from pasting in my text box what is the best way to trap the keyboard commands and stop the paste menu from poping up on right click?
|
|
|
|
|
Hello Tyrus,
In this case you should use the KeyDown Event.
this.textbox.KeyDown += new KeyEventHandler(CheckKeys);<br />
<br />
<br />
private void CheckKeys(object sender, KeyEventArgs e)<br />
{<br />
if (e.Control && e.KeyCode == Keys.V)<br />
e.Handled = true;<br />
}
All the best,
Martin

any idea how i can disable the context menu that pops up with i right click?
|
|
|
|

Hello Tyrus,
Maybe for your project it would be helpfull if you use a MYTextBox class which inherits from windowsd Textbox.
There you can override the MouseUp Event.
protected override void OnMouseUp(MouseEventArgs e)<br />
{<br />
if(e.Button != MouseButtons.Right)<br />
{<br />
base.OnMouseUp (e);<br />
}<br />
}
Hope it works for you!
All the best,
Martin

On the body tag just write the following code. It will disable the right Click in a page.
<body oncontextmenu="return false">

Hi everyone.
I have a question!
There are some programs like Desktop Plant, that the application windows are behind the desktop icons and in front of the background window! You can move the plants and put them everywhere!
You can download it here, it's free to try and just 873 KB:
http://www.desksoft.com/DesktopPlant_Download.htm
Does anyone know how to do that?
I really like to learn it.

Hi Divyang Mithaiwala,
Thanx for attention, but as I know, the plants are window, cause they have their own process and if you find and download the TaskManagerEx program in the articles, you will see that the process has a window, and I'm almost sure that it is the plant window.
I know that there are some windows that make the main shape of the windows UI, and they have names like "Desktop" that makes the desktop window containing the task bar man desktop icons and a window named "Program manager" that contains the desktop icons and desktop elements, and when you hide this window, the whole wdesktop elements will become hidden!
So I wrote a program that maks a window form and makes it the child of the "Program Manager" window and It became one of the thesktop elements, but the problem is that even when I try to set the "Z Order" to the lowest window, my window will stay in front of the Icons and the plants even!

I am trying to pass an Excel.Application object from c# to c++ DLL via PInvoke.
The c++ code expects an IDispatch.
The Pinvoke Wizard paulyao.com suggests:
[DllImport("myDLL.dll")]<br />
public static extern short Initialise(ref LPDISPATCH pExcel);
so I have tried this code c#:
[DllImport("myDLL.dll")]<br />
public static extern short Initialise([MarshalAs(UnmanagedType.IDispatch)]ref object pExcel);
and
[DllImport("myDLL.dll")]<br />
public static extern short Initialise([MarshalAs(UnmanagedType.IUnknown)]ref object pExcel);
And this is the code that calls the routine.
Excel.Application excelApp= (Excel.Application)application;
object o=(object)excelApp;<br />
Initialise(ref o);
When the c++ code is called it throws a COleDispatchException error. m_wCode is 00000000 and 80020005 respectively.
Any ideas on how I should pass the Excel Application object?
Regards
Alias47
