hi,
you can change the tool tip text when ever needed.
toolTip1.SetToolTip(this.button1, "My button1");
the follwing was from an external help:
The following code example creates an instance of the ToolTip class and associates the instance with the Form that the instance is created within. The code then initializes the delay properties AutoPopDelay, InitialDelay, and ReshowDelay. In addition the instance of the ToolTip class sets the ShowAlways property to true to enable ToolTip text to always be display regardless of whether the form is active. Finally, the example associates ToolTip text with two controls on a form, a Button and a CheckBox. The code example requires that the method defined in the example is located within a Form that contains a Button control named button1 and a CheckBox control named checkBox1, and that the method is called from the constructor of the Form.
Visual Basic
' This example assumes that the Form_Load event handling method
' is connected to the Load event of the form.
Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles MyBase.Load
' Create the ToolTip and associate with the Form container.
Dim toolTip1 As New ToolTip()
' Set up the delays for the ToolTip.
toolTip1.AutoPopDelay = 5000
toolTip1.InitialDelay = 1000
toolTip1.ReshowDelay = 500
' Force the ToolTip text to be displayed whether or not the form is active.
toolTip1.ShowAlways = True
' Set up the ToolTip text for the Button and Checkbox.
toolTip1.SetToolTip(Me.button1, "My button1")
toolTip1.SetToolTip(Me.checkBox1, "My checkBox1")
End Sub
C#
// This example assumes that the Form_Load event handling method
// is connected to the Load event of the form.
private void Form1_Load(object sender, System.EventArgs e)
{
// Create the ToolTip and associate with the Form container.
ToolTip toolTip1 = new ToolTip();
// Set up the delays for the ToolTip.
toolTip1.AutoPopDelay = 5000;
toolTip1.InitialDelay = 1000;
toolTip1.ReshowDelay = 500;
// Force the ToolTip text to be displayed whether or not the form is active.
toolTip1.ShowAlways = true;
// Set up the ToolTip text for the Button and Checkbox.
toolTip1.SetToolTip(this.button1, "My button1");
toolTip1.SetToolTip(this.checkBox1, "My checkBox1");
}
C++
// This example assumes that the Form_Load event handling method
// is connected to the Load event of the form.
void Form1_Load( Object^ sender, System::EventArgs^ e )
{
// Create the ToolTip and associate with the Form container.
ToolTip^ toolTip1 = gcnew ToolTip;
// Set up the delays for the ToolTip.
toolTip1->AutoPopDelay = 5000;
toolTip1->InitialDelay = 1000;
toolTip1->ReshowDelay = 500;
// Force the ToolTip text to be displayed whether or not the form is active.
toolTip1->ShowAlways = true;
// Set up the ToolTip text for the Button and Checkbox.
toolTip1->SetToolTip( this->button1, "My button1" );
toolTip1->SetToolTip( this->checkBox1, "My checkBox1" );
}
J#
// This example assumes that the Form_Load event handling method
// is connected to the Load event of the form.
private void Form1_Load(Object sender, System.EventArgs e)
{
// Create the ToolTip and associate with the Form container.
ToolTip toolTip1 = new ToolTip();
// Set up the delays for the ToolTip.
toolTip1.set_AutoPopDelay(5000);
toolTip1.set_InitialDelay(1000);
toolTip1.set_ReshowDelay(500);
// Force the ToolTip text to be displayed whether or not the form
// is active.
toolTip1.set_ShowAlways(true);
// Set up the ToolTip text for the Button and Checkbox.
toolTip1.SetToolTip(this.button1, "My button1");
toolTip1.SetToolTip(this.checkBox1, "My checkBox1");
} //Form1_Load

I know that solution, but here it is not possible to update the text of the tooltip automatically.
The only solution to solve this is to generate an event OnDataChanged and then to update the ToolTip text...

i am making a game using C#. a lot of the game variables, i am storing in hash tables. lately whenever i am trying to run the program i am facing outofmemoryexception.
i was not facing this problem before; and has erupted suddenly.
can you suggest a better way to store game information?
please help

What kind of data and how much are you talking about?
|
|
|
|
|
I suggest to not use much variables because it become large proccess when u run it and slows ur PC as well..

The key thing I hear is "Hash Tables", i.e. plural. Sounds lke you have a added so much data that you have basiscaly overfilled the sink.
The answer I am about to give may not be easy to deal with but it sounds like you are at the point of fix or scrap. Here is what I would do: First perform a full evaluation of the design to determine how much data really needs to store in a persistent manner, how much is ephemeral in nature, and finally what is the best way to store all this stuff? Remember a hash table is a fair amount of code that comes at the expense of memory. However in a game "speed" is the chief criterion. Thus finding a viable storage mechanism and keeping memory utlization reasonable should guide the solution.
For these reasons I would think about creating a more efficient storage strategy. This takes into account things like graphics, you only need one copy and after that you should only store the deltas. Sure this means GDI programming but your are writing a game afterall. Game design is almost always equated with system code, and in C# that equates to unmanaged code. If you create a memory storage strategy and implement memory allocatio via Marshalled OS calls and pointers, then you are on the right track. For sure, any game write should know exactly how much data needs to be stored, how much needs to be paged in from disk, etc.
Although C# is nice for lots of applications, I personally would use C++ for a game because of the closer fit to the OS. At the same time you can always write DLLs in C++ if you need the performance tweaks.
Good Luck

I have managed to change the colour of tabpages. I also managed to change the fonts of each tab to my own font. Now my application is in my user defined colour EXCEPT for the tabs for the tabcontrol, how do I change that?!

Can you show some code of how you are using it?
|
|

There are some excellent articles here on TraceListeners, I recommend starting there. You can create you own trace logging methods like this:
<br />
public class MyTrace <br />
{<br />
private readonly string tracePath;<br />
private StreamWriter writer;<br />
<br />
public MyTrace( string filename )<br />
{<br />
this.tracePath = filename;<br />
}<br />
<br />
public bool Open( )<br />
{<br />
try<br />
{<br />
writer = new StreamWriter( tracePath );<br />
return true;<br />
}<br />
catch<br />
{<br />
return false;<br />
}<br />
}<br />
public void Log( string format, params object[] args )<br />
{ <br />
if ( writer != null )<br />
{<br />
string msg = string.Format( format, args );<br />
writer.WriteLine( msg );
}<br />
else<br />
throw new Exception( "Trace File must be opened" );<br />
}<br />
public void Close( )<br />
{<br />
writer.Flush( );<br />
writer.Close( );<br />
writer = null;<br />
}<br />
}<br />

Hi there!
I try to serialize Unit struct into XML,
<code>XmlSerializer xs = new XmlSerializer(typeof (Unit));
MemoryStream s = new MemoryStream();
xs.Serialize(s, new Unit(100));
Console.WriteLine(Encoding.UTF8.GetString(s.ToArray()));</code>
Then I got following XML:
<code><?xml version="1.0"?>
<Unit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" /></code>
There is no data in this XML.
Ummm, need helps, thanks.

The Xml serializer requires the fields to be public.

Hi, im using MCI to play wave files.
I need to control the balance of one of this but i havent been able to do it.
Ive tried the command string "set id audio left off" but i get an error message (the device isnt compatible with the specified command).
Any idea or api i could use?
Thanks

Hi!
You could use the mixer API to control the balance (and to find out whether a device/mixer line supports setting balance).
There are several articles here on this topic, for example this one.[^]
