Have a look at this[^]. Though this is for DataGrid, but DataGridView should also behave same. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

I'm building a game in C# and i need your help in something...
It's a simple game, no graphics, just text background and voice.
the game itself is built on choices,I mean that every now and than in the game the player has to chose between a couple of choices.
so I'm putting 4 buttons and i want that every time the player has to chose, he'll be able to press the button the text will change and so on.
so here my questions:
how can i make it that every time there is a choice it will change accordingly and the button won't be tied to one line?
thanks a lot!!!

sorry...
I meant that how can i make the Text change accordingly to the choice by one of the buttons?

You write code code in the Click event handler of the buttons...

C# controls have a "Text" attribute. Assigning a string to this attribute will change the control's text. For example:
System.Windows.Forms.TextBox nextQuestion;
...
nextQuestion.Text = "What was the name of Paul McCartney's first band?"; or
System.Windows.Forms.Button nextAnswerButton;
...
nextAnswerButton.Text = "The Beatles";
|
|
|
|
|
so if my buttons name is "button1" so it will go something like this?
System.Windows.Forms.TextBox button1;
...
button1.Text = "What was the name of Paul McCartney's first band?";
|
|
|
|
|
|
but the question is how will the program know to which text to go?
i mean do i have to declare something or something like that or any other action?
thanks a lot!!!

Whatever string you assign to the text member will appear on the screen. It's your decision.
|
|
|
|
|
can you show me how i assign a string to a text please and in what section of the code i write it in?
thanks!!!!!!

You need to learn how to program in C#. There are many tutorials on the Web. They're free.
|

You need to dynamically create your choices based on the allowed choices. You can still use the same event listener if you utilize the Tag property in windows forms based applications, or in web forms based applications you will be able to use the ClientID property.

what do you mean by "dynamically create your choices"?
|

It is possible to develop your user interface at run time without the benefit of using the Visual Designer. By doing so you will have complete control over the look, placement, actions, etc. of these buttons. Creating controls at runtime is called dynamic creation. There are many articles available that can shed a lot more detailed light on the subject than I can in a brief post.

Hi everybody.
How can I Abort all created Thread ?
For example :
I created a button that creates a thread by clicking on it.
Now I want close all of open Threads when my WinForm close.
|
|
|
|
|
When you create the threads, set the IsBackground property to true.
Then these threads are terminated when the app closes.
----------------------------------
Be excellent to each other
|
|
|
|
|
The threads belong to the process they were created from and cannot exist outside it. When the process is terminated, all it's threads are too.
|
|
|
|
|
I like to create member variables for the the class that contains the run method in my thread and then have a thread-safe method in said class that allows graceful termination of the run method.
If I have a form that closes I create an listener on the OnClosing event and then signal, or request from the threads to stop gracefully.

that is system dll, im invoking it...
this is code..
[DllImport("user32.dll", CharSet = CharSet.Auto)]<br />
public static extern IntPtr RegisterDeviceNotification(IntPtr hRecipient, DEV_BROADCAST_DEVICEINTERFACE NotificationFilter, UInt32 Flags);<br />
<br />
[DllImport("user32.dll", CharSet = CharSet.Auto)]<br />
public static extern uint UnregisterDeviceNotification(IntPtr hHandle);<br />
<br />
[DllImport("setupapi.dll", SetLastError = true)]<br />
public static extern IntPtr SetupDiGetClassDevs(ref Guid gClass, UInt32 iEnumerator, IntPtr hParent, UInt32 nFlags);
List< string > HWList = new List< string >();
public list< string > getAll()
{
Guid myGUID = System.Guid.Empty;
IntPtr hDevInfo = Native.SetupDiGetClassDevs(ref myGUID, 0, IntPtr.Zero, Native.DIGCF_ALLCLASSES | Native.DIGCF_PRESENT);
if (hDevInfo.ToInt32() == Native.INVALID_HANDLE_VALUE)
{
throw new Exception("Invalid Handle");
}
Native.SP_DEVINFO_DATA DeviceInfoData;
DeviceInfoData = new Native.SP_DEVINFO_DATA();
DeviceInfoData.cbSize = 28;
DeviceInfoData.devInst = 0;
DeviceInfoData.classGuid = System.Guid.Empty;
DeviceInfoData.reserved = 0;
UInt32 i;
StringBuilder DeviceName = new StringBuilder("");
DeviceName.Capacity = Native.MAX_DEV_LEN;
for (i = 0; Native.SetupDiEnumDeviceInfo(hDevInfo, i, DeviceInfoData); i++)
{
while (!Native.SetupDiGetDeviceRegistryProperty(hDevInfo,
DeviceInfoData,
Native.SPDRP_DEVICEDESC,
0,
DeviceName,
Native.MAX_DEV_LEN,
IntPtr.Zero))
{
}
HWList.Add(DeviceName.ToString());
}
}
In the HWList Array all the devices are listed, but i need to check which device is connected to serial port(may be is it possible to do with the Device ID)
