Hi,
In my project I use a TreeView in which all nodes are supposed to be sorted in alphabetical order. When the user edits a node label I want the TreeView to automatically sort itself. Using the following code I am able to make it work for the top level nodes but not their children.
<br />
protected override void WndProc(ref Message m)<br />
{<br />
base.WndProc(ref m);<br />
<br />
if (m.Msg == 0x004E)
{ <br />
SendMessage(treeView.Handle, 0x1113, 1, 0);
}<br />
}<br />
Any help would be greatly appriciated!

Can you use the TreeView.Sorted property and set it to true?
"we must lose precision to make significant statements about complex systems."

Unfortunately not, setting the TreeView.Sorted to true makes the TreeView sort the nodes upon insertion but not after editing a node label.
|
|
|
|

Cool. That makes sense.
Then, how about setting the Sorted value to true, subscribing to the TreeView.AfterLabelEdit event, and, after the label gets edited, do something like:
public void EventHandler( object o, NodeLabelEditEventArgs nleea )
{
TreeNode node = ( TreeNode ) o;
if( TreeNode.Parent != null )
{
TreeNode.Parent.Remove( node );
TreeNode.Parent.Add( node );
}
}

Hi
How do I compare 2 strings, ignoring their case. For instance, I want to achieve the following result:
bt = BT > true
GD = BT > False
bT = Bt > true
regards
|
|
|
|
|
Use the string.Compare method:
string.Compare(string strA, string strB, bool ignoreCase)
---
b { font-weight: normal; }

Read everything I can find on .dll's but I'm still stuck -
I recently purchased a usb device controller (PC BEE) online and have managed to get it working ok, however I want to talk to it with Matlab 7.0.
I've been provided with .dll file - 'bee.dll' and a .def file - bee.def. However as I've no header I cant use the loadlibrary command in matlab
Apparently there are only two functions:
typedef BOOL (*TypeBeeInit)();
typedef void (*TypeBeeOut)(unsigned long bits);
So the header should be quite small, but I have no idea how to write it!!!
Can anyone help!?! 
---------------------------------------------------------------------
I've included the .def file if that's any use:
; bee.def : Declares the module parameters for the DLL.
LIBRARY "bee"
DESCRIPTION 'bee Windows Dynamic Link Library'
EXPORTS
BeeInit
BeeOut

Where is the DLL present? Is it in the application directory? Does it have any dependent DLLs?

is using it.

I think it's a location, "2 nautical miles west southwest of Nellieville" (wherever that is).
|
|

|

No, it's a position.
If I'm not mistaken: Two nautic miles west-south-west of Nellieville.
I believe that the intention of giving this position was to supply a nonsense answer to a nonsense question...

Hi,
What language do you speak best... maybe someone here can talk to you in that language. There are lots of people here 
In case you can understand english fairly well, a thread is like a separate running "bit" of code. One common use is to load data on a separate thread to the user-interface so that the interface remains responsive and does not "hang". You can find many many articles on Threading here at code project or via a search on google.
Good luck, and sorry for the original sarcastic answer

Can you recomend any good scheme/product for protecting a .Net application against piracy? Something that can be used for when you have a production application.
It seems to me there isn't too many options out there, as all assemblies compile into IL, which is wide opened for anybody who wants to look into it.
Thanks.

Lock every copy in a safe. Or buy an expensive obsfucator before you start, so that your clients can't find your protection method and disable it. Then really if you want to stop your program being distributed, your program needs to access the web, and your copies need unique keys, so that you can verify that each key is in use on one machine only.

hi,
i am having a problem accessing an enum.
i declared enum as:
public enum Rating {Good,Bad}
i have no problem accessing from the same class but i cannot access it from the other class though i can access the methods defined in the class where enum is specified.
will really appreciate if u can let me know what i did wrong here.

Because you put the enum inside a class, you have to prefix the classname before it.
class A
{
public enum B
{Good, Bad}
}
class C
{
void Method()
{
A.B b = A.B.Bad;
}
}
Regards
Senthil
