Hi Mark.
I think the simplest way to do this would be to use XmlSerializer [^]class. Using this class, you just mark your class with the [Serializable] attribute, then when you want to save your object:
XmlSerializer serializer = new XmlSerializer(typeof(Terrain));
serializer.Serialize(someFileStream, myTerrainInstance);
And when you want to load a saved terrain object:
FileStream terrainFile = ...;
Terrain myTerrainInstaince = (Terrain)serializer.Deserialize(terrainFile);

I'm also a great fan of the XmlSerializer but according to a discussion I recently had in the XML forum it does not support the IDictionary interface. Therefore instances of the Dictionary though marked as Serializable cannot be used with the XmlSerializer.

You're right, however, there are workarounds[^].

Thanks Juda, I'll give that a try. I think this is exactly what I'm looking for.

Hi all,
i'm working on CheckedListBox, where in which i am using itemCheck event To capture the checked and unchecked values of checkboxes of CheckedListBox,
But here if Am loading some values
|
|
|
|

The common thing to do is to set a flag that tells you to ignore the event, within the event itself. If it's on page load tho, you could just hook up the event handler AFTER setting your values.

ya i've taken a flag, saying for the first time[when count is zero] i have restricted my itemCheck event code,
but its not working
int count=0;
if (count != 0)
{
if (e.NewValue == CheckState.Unchecked)
{
lstChcked.Items.Remove(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
else if (e.NewValue == CheckState.Checked)
{
//ChklbxAdd= Convert.ToString(chklstMultipleMdfyTbl.CheckedItems.Count);
// string[] ChklbxFill = new string[chklstMultipleMdfyTbl.CheckedItems.Count];
lstChcked.Items.Add(chklstMultipleMdfyTbl.SelectedItem.ToString());
}
}
else
{
MessageBox.Show("try to restrict this event");
}
}
I DIDN't Understand ur last line,
***you could just hook up the event handler AFTER setting your values.**

It's the same thing I'm telling you over and over again.
BTW, your count flag cannot work since you obviously defined it inside the event handler, so it will always have the same value (0) when execution reaches the if statement. The flag has to be an instance field that preserves its value between subsequent executions of the event handler. Furthermore, it would be sufficient to use a boolean instead of an int.

In Visual Studio, add a Setup project. Click on the setup project's file system editor. Right-click, add special folder-> users start menu. There, add a shortcut to the uninstaller.

I am trying to create a TabPage as separate object. I can edit them iside s tab control allright, however, I can't create or edit the control layout of a separate TabPage.
When I create a user control (or a form), and change the base class to "TabPage", the editor changes to a generic controll collection.
What can I do?

I don't think there is a Visual Studio designer that allows you to layout tab pages visually. If you really need this, I think you're going to have to create your layout as a custom control, then add that to the tab page at design time.

This actually was easier than I thought - thanks!

I was searching for how windows detect MMC or SD or Flash disk and bring up a dialog that gives you options to open folder or in windows media player..etc. ...
I want to build application that make the same...
I had made an application that detect any change in disks generally but for example ( I'm intereted in MMC ) my application can detect the memory reader when it's plugged or unplugged but when I insert a memory stick in the reader it doesnot detect any change ...should I make timer that watch the memory reader all the time!! I think it's not good way..so any one has any solution for this??? and this dialog that windows brings up is from shell32.dll so any one knows how to know the function and its parameters??
thanks in advance

Ok I you create a new C# windows project and then create a ".settings" with an item (string) and (user) as the type. Now this will create an app.config file associated with the project. Go into the properties for the app.config and change the Build Action to (Embedded Resource). Now in your windows form create and edit box and a button which loads and saves the setting that your created.
Build the project. Go into the bin folder and click on the exe file to run the project. Try changing the settings and saving the settings. Close the project and load it back up by clicking on the exe file to verify that the save works which it will.
BUT WHERE DOES IT SAVE TOO??????????
I cant figure it out......

Hi,
It saves it somewhere in C:\Documents and settings\UserName\LocalSettings\Application Data \Your Application Name .Exe XXXXXXXXXXXXXXXXXXXXXXXXXXX\VersionNumber\user.config
Try search *.config in your documents and settings and u will find it.
That's because .Net wants to save Config settings for each Windows user. so it does not touch the application.config file that can be shared between many users.
That happens even u don't set the Build action to Embedded Resource wich is not logic because the config file must not be embedded in the exe.
HTH.

Hi, I am just beginner in .NET with C#. In my study, I have learned that when an instance of a class created in the heap is not owned by reference (a variable of that class) , the Garbage Collector (GC) removes this instance from the memory after a while. In my first small application in .NET, I hasitate in a point that When I am testing a click event of a button control of my Form1 class, I declared a variable of type a Form class (let's say Form2). The View is like this:
private void button1_click(....)
{
Form2 myForm2 = new Form2();
myForm2.Show();
}
Here when the execution gets out of the click event, then I expect that the local "myForm2" becomes out of scope for availibility. But my new form (Form2) still apears on my screen. Why? Cause no availiable reference to this Form2 instance anymore, immediately after the button click event routine. Anything I need to know more about "scopes" and GC ?
|
|
|
|
|
As u have created reference of form2 from form1's button click event so this reference of form2 will remain in scope till the form1 is in scope and as soon u will close the form1 the reference of form2 will also be lost and GC will reclaim the memory back and will close the form2 also.

First, I'd really like to thanks to you rah_sin for your answer..
I need one more point: What you explain is valid for only class of Form or those inherited from Form class? Cause as you hv seen in my example the refernce "myForm2" is not a direct member of Form1 class but a local declaration in button click event. Or should I understand that Show() method of Form class, saves or register its reference into a global collection internally or somewhere in caller form ?
In other words, what if my locally declared variable was of simple class like:
class Sample
{
private string sName;
private int nIdNumber;
public Sample()
{
//...
}
public string Name
{
get {...}
set {...}
}
//...
}
private button_click(....)
{
Sample mySample = new Sample();
mySample.Name = "Testing Name";
}
