The definitive answer is "Maybe". No, I'm not kidding around.
You're going to have to recompile the app under SP1, then install it on a machine without SP1 on it and test it. It's that simple! It's the ONLY way you're going to get the DEFINITIVE answer.
"led mike" was correct in every way, only YOU can answer that question: "will your app work??" You're not going to know until YOU test it, and that testing is not limited to strictly functionality. The other question you have to answer is performance. Sure, the app may work, but does it do so with acceptable performance??

Sp1 contains two types of stuff.
1) New libraries (e.g. the entity framework).
Provided you don't go using these, it won't matter that your users don't have them. You will need to be very careful to make sure you don't accidentally use some new sp1 functionality that your users don't have.
2) CLR improvements. (e.g. various performance improvements to WPF loading times etc). It doesn't matter that your assembly is compiled against 3.5 SP1 on your PC, it will still work on a PC with just plain old 3.5, but you just won't see any of the improvements.
So in theory it should work fine, but as with anything in development, I wouldn't bet your life on it. The best way forward is probably to ensure you test thoroughly on a 3.5 pc without sp1 before deploying it to your users.

Is there implementation SiteLock interface for ActiveX on C#?
or C# and .NET is not good option to make ActiveX?
Thanks

Hey Dudes (Dudets),
I read this awesome article IDisposable: What Your Mother Never Told You About Resource Deallocation[^] and a bunch of other not so awesome ones.
However, I failed to find an answer to this question:
1. I got a base class - ObjectA that inherits from a UserControl.
2. ObjectA is then inherited from by ObjectB and tailored to particular uses elsewhere in the code. (ObjectB is not inherited from)
3. There are many different ObjectB implementations (ObjectB1....10) all of which add EventHandlers for ObjectA events and declare their own distinct events that are handled by other objects.
4. Now all ObjectBx objects are stored in a collection and then disposed off like so:
For Each oA as ObjectA in CollectionOfObjectBx
oA.Dispose
Next
5. Each ObjectBx overloads Dispose method and uses it to Remove EventHandlers.
However, these Dispose overloads never get called because instances of the ObjectBx are disposed via the base class that is not aware of anything going on inside inherited objects.
But does it matter? Want GC eventually kill off all handlers since the objects themselves are dead?
I would greatly appreciate if anyone could shed some light on this.
Regards
Alex

Hi, you need to override and not overload. all dispose methods should be called from the leaf type to the top. I think that you should clean up after your self when creating objects that are disposable. in large objects you should also set values to null explicitly to free the memory faster. The next code calls all methods when disposing:
///
/// The main entry point for the application.
///
[STAThread]
static void Main()
{
//This code should go in the main
//ObjectB1 inherits from ObjectB which innhertis from ObjectA
ObjectB1 b1 = new ObjectB1();
//Calling the dispose will call the dispose of ObjectB1
//within the dispose of ObjectB1 there is a call to the base dispose.
b1.Dispose();
}
public partial class ObjectA : UserControl
{
public ObjectA()
{
InitializeComponent();
}
private void ObjectA_Load(object sender, EventArgs e)
{
}
}
public class ObjectB : ObjectA
{
public event EventHandler ObjectBEvent;
public ObjectB()
{
this.MouseClick += new MouseEventHandler(ObjectB_MouseClick);
}
void ObjectB_MouseClick(object sender, MouseEventArgs e)
{
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
MessageBox.Show("Dispose : ObjectB");
ObjectBEvent = null;
}
protected virtual void OnObjectBEvent(EventArgs e)
{
if (ObjectBEvent != null)
{
ObjectBEvent(this, e);
}
}
}
public class ObjectB1 : ObjectB
{
public event EventHandler ObjectB1Event;
public ObjectB1()
{
this.MouseClick += new MouseEventHandler(ObjectB1_MouseClick);
}
void ObjectB1_MouseClick(object sender, MouseEventArgs e)
{
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
MessageBox.Show("Dispose : ObjectB1");
ObjectB1Event = null;
}
protected virtual void OnObjectB1Event(EventArgs e)
{
if (ObjectB1Event != null)
{
ObjectB1Event(this, e);
}
}
}

Hey Natza,
Thx for taking the time to answer my post. Unfortunately your solution doesn't help.
You are disposing ObjectB1 which would have worked if not for the fact that the generic dispose proc that sits in Main only knows of ObjectA and has no idea that ObjectA was inherited from.
In a word you are suggesting Top Down Dispose method calls.
But I need the Dispose methods to be called Down to Top first e.i. the last inheritor ObjectBx needs to be notified when the base class is being disposed. Once that's accomplished i can go down the inheritance tree and kill off my handlers.
Lastly, there is a twist. A few of ObejectBx's events are handled by ObjectC that is only destroyed on app shutdown.
Hence, there is a live reference remaining in memory to all ObjectBx events even after they are disposed.

I think there is a workaround for this i'll post more in a bit.

Hi I dont know whether I understand what you are trying to do.
Note that ObjectB1 dispose is called first even when using:
ObjectA a = new ObljectB1();
a.Dispose();
And it does not matter whether they know each other or not.

How do you overload Dispose? I'm guessing you have public non-virtual Dispose in your base class and then methods with the same signature in all the derived classes?
If that's the case, you need to make the method that does the disposal virtual, and override it in the derived classes. That way, the Dispose calls will go the actual (runtime) types - in your case, ObjectBxs.

Come one Pete, give the guy a break. He wants to create ASP.NET. That would be good for all of use right?
[typo-caused-by-nervous-finger-energy] As I read that now I can only imagine what sort of quips you might use on that.

Hi,
actually i have to insert an invisible watermark in MSword files using c#.can anyone help me?
|
|
|
|

How do you mean "an invisible watermark"? My definition of a watermark is that of a semitransparent image displayed behind text. Obviously, semitransparent != transparent. Are you referring to permissions, which will allow only certain users to view and edit a file?
|
|
|
|

"invisible watermark is a process that embeds data that is not perceptible". there are different techniques which allow to embed invisible and unremovable data to images.But i want to embed invisible and unremovable data into text documents such as MS word documents using c# program.if u know anything then plz do reply me

I already finished your project for you. If you execute a test you will find that your requirements have been satisfied. Once you have done that we can discuss payment for services rendered.

Sure, here is how I solved the requirement of having an invisible watermark.
1) Print the document
2) Open your eyes, you cannot see the watermark because it is invisible. REQUIREMENT SATISFIED

Could you not generate an image with meta text.
If you look at the file format of a *.jpg or *.tiff. You might find a space to embedded it there. There is usually some header tags. Owner, author etc...
or
Depending on the image type you could create your own colour pallet. the first spot representing the color white or what ever background color. The others represent your message in char. Different color depths can increase the size of your message.
8 bit would be useful for an ascii message. 'A' 41 0101 0001
rgb could be three charactors. 'ABC' 414243
so
#000000 - white
#414243 - ABC
Might be a start
Could use 7 bit ascii and gain a few characters
or
create a style sheet with colors representing a message
For another idea:
compress your message to make it smaller and hide the message a little more
