So, the solution was to refresh the currency manager after resetting the data source by adding the following two lines:
CurrencyManager* cm = __try_cast<CurrencyManager*>(BindingContext->Item[search_results_list]);
cm->Refresh();

Hi all,

Hi All,
What's the equivalent of CScrollView in .NET? I'm looking for something to let me draw large vector diagrams in a scrollable, zoomable view, then print them either on multiple pages or scale-to-fit, and nothing seems to fit the bill.
Any suggestions gratefully received!

Should I implement an IEnermable interface explicitly?
#region IEnumerable<Range> Members
IEnumerator<Range> IEnumerable<Range>.GetEnumerator()
{
foreach (Range r in ranges)
yield return r;
}
#endregion
#region IEnumerable Members
System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
{
throw new NotImplementedException("Non-generic enumerator");
}
They both cannot be implicit because C# does not allow overloading methods that only differ by return type. In what senerio should GetEnermerator be explicit rather than implicit? How do you usually implement yours? Also should I implement anything in the non-generic GetEnumerator method?

I'm not sure I understand the question, but I would probably change that first method to
<br />
IEnumerator IEnumerable.GetEnumerator() <br />
{<br />
return ( ranges.GetEnumerator() ) ;<br />
}<br />

I am curious to whether I should implement the interface explicitly rather than implicitly. If I implement it explicitly I will not be able to call the GetEnumerator method unless I cast the instance of my class to IEnumerable(I think). Do you usually implement your IEnumerable interfaces explicitly, and do you implement any functionality in the non-generic GetEnumerator method?

Why does your generic GetEnumerator method return a non-generic enumerator?

CP seen those as HTML tags and removed them, I should have checked "ignore html tags" when I posted it. It is generic in my project.

I see.
If you let Visual Studio create the stubs for implementing the interface, this is what you get:
public class test : IEnumerable<string> {
#region IEnumerable<string> Members
public IEnumerator<string> GetEnumerator() {
throw new Exception("The method or operation is not implemented.");
}
#endregion
#region IEnumerable Members
IEnumerator IEnumerable.GetEnumerator() {
throw new Exception("The method or operation is not implemented.");
}
#endregion
}
This makes the non-generic method explicitly implemented. I think that will work the best, as you should prefer the generic method unless you are using a reference to IEnumerable.
I would implement both of them, even if one is rarely used. There might be a situation where you would need the non-generic one.

Is it possible for me to use the yield statement in the non-generic GetEnumerator method? If so should I then make the generic version call and return the return value of the non-generic GetEnumerator method which would contain the iterator logic with the yield keyword? What is the best practice for implementing the IEnermerable interface?
I figured out a better way, I will just return the enumerator for the internal array.

I wrote some C# code to send an e-mail using System.Net.Mail.SmtpClient. This allows me to specify the sender, receiver, message, etc., and it works on one SMTP server perfectly. However, when I tried using AOL's SMTP server instead, I was getting authentication failures from their server. Using my regular e-mail program (Eudora), I CAN send to AOL's SMTP server.
The only apparent difference between the two programs is that Eudora does this:
EHLO name..
AUTH LOGIN..
<credentials>..
The program I wrote using SmtpClient does this:
EHLO name...
AUTH LOGIN <credentials>..
AOL's SMPT server rejects the latter, saying "501 INVALID SASL FORMAT OR LENGTH".
I don't know if what AOL's server is doing is breaking any rules or not, but that's kind of beside the point. Is there any way to adjust the SmtpClient object to be more "friendly" to AOL? If not, is there another class I can use?

I have my collection displayed as property in PropertyGrid.
How can I prevent the collection from being editable by .NET Framework's Collection Editor Dialog Box?
Thanks.
|
|
|
|
|
if i understand correctly
[Browsable(false)]<br />
public CollectionType Collection<br />
{<br />
get{;}<br />
set{;}<br />
}
|
|
|
|
|
No, this is not what I mean...
"[Browsable(false)]" on my collection tells the property grid not to display the collection in the grid.
Whereas I _need_ the collection to be displayed; at the same time the collection is expected to be in "read-only" mode.
Thanks.
|
|
|
|
|
Oh sorry man.
You define only the get function.
Now if you want the property to be read/write but only readonly in the designer i realy haven't used it but i think there might be a readonly attribute like browsable.
Let me know. Thank you.

I have a managed dll that captures webcam video with Directshow. I could easily display the video in .NET 2.0 by drawing on the background of the panel. There is just an abstract Panel in .NET 3.0, other Panels (Dockable,..) have no Graphic object I could draw with nor any background I could set my images to.
I tried the following:
BitmapSource bitmap = BitmapSource.Create(320, 240,
96, 96, PixelFormats.Rgb24, null,
Streaming.samplePointer, 357480, 320 * 3);
dockPanel1.Background = new ImageBrush(bitmap);
dockPanel1.InvalidateVisual();
It didn't work. It just fills my memory periodically if I observe Task Manager, but it displays nothing. And streaming works perfectly well under 2.0 by drawing on a Panel. What should I do? How is this situation supposed to be handled in 3.0?

Hi All,
How can I change the build version of the generated DLL file in Visual Studio 2005 webproject??
I want it to be changed automatically each time I build the project.
Thanks all

In your AssemblyInfo file, there is a section that looks like this:
<br />
[assembly: AssemblyVersion("1.2.1.*")]
This controls the assembly version. The asterisk at the end shows that the revision will be autoincremented. If you want to autoincrement the build number, place a * there as well.

Yes. Lots of people. And lots of them can be found through Google.

Yes, I tried with google. But I couldnt find it in nice way(may be my query was in incorrect matching, because google works on it only), if you have any link please provide it to me, no. Please. Thank you.
