I think this would work if I were on the same server but my issue is I am trying to get the files from another server. Although I am using a virtual path I have to actually change the "Server". Isn't there a way to use a "http://server/folder" path for this?

I have an ArrayList populated with UserControl objects. I need to display this list on a windows form and when a user clicks on any of the items I need display the properties of the control.
I thought I could use ListBox control since we can populate it with the objects. But the problem is that when I populate the list box I dont get any text values. And if you click on the list box you can clearly see where the items were populated but no textual representation for it.
foreach(UserControl c in mb.UserControls)
{
listBox1.Items.Add(c);
}
unless i do:
foreach(UserControl c in mb.UserControls)
{
listBox1.Items.Add(c.ToString());
}
Its something really simple but for some reason I am not getting it. Would appreciate some help. Thanks.

Any time you want a list of thing more complex than strings you are likely better off to use the ListView Control

Listbox.Items is an ObjectCollect so it can store strings as well as ListBoxItems
only two letters away from being an asset

Hi,
a ListBox is great at showing a collection of objects in a vertical list. There are basically two
ways to visualize the items:
1.
provide a ToString() method that returns the string you want; it could show whatever
member(s) of the item, or some other calculated value. This way always renders a single
string, all in one color.
2.
or make the entire ListBox userdrawn; by providing a paint handler to the DrawItem event,
you can paint anything you like, even the actual look of the UserControl itself...
You probably will want to show selected items in a different way than unselected ones, e.g.
a different background color.

well I ended up doing something like this:
Dictionary<int, UserControl> dic = new Dictionary<int, UserControl>();
...
int count = 0;
foreach (UserControl c in mb.UserControls)
{
listBox1.Items.Add(c.Name);
dic.Add(count, c);
count++;
}
and when user double clicks a control I simply use the selectedIndex to pull the control out from dictionary
foreach (KeyValuePair<int, UserControl> kvp in dic)
{
if (kvp.Key == listBox1.SelectedIndex)
{
MessageBox.Show(kvp.Value.Name, kvp.Value.Size.ToString());
winForm.Controls.Add(kvp.Value);
}
}
is that a terrible solution?

Hi,
if it suits your needs, then it is fine.
One remark though: since all your keys are different (as they should),
and a dictionary has an indexer (i.e. can be read as if it were an array),
there is no need to search for a specific item, you could simply do:
int index=listBox1.SelectedIndex;
if (index>=0) {
UserControl uc=dic[index];
MessageBox.Show(uc.Name, uc.Size.ToString());
winForm.Controls.Add(uc);
}
BTW: you don't really need a Dictionary, a simple List< UserControl> would work
the same way.

Can anyone help me with this monster? I want to be able to do collision detection for ALL OF my StaticBLocks (with the Player: BTW both 25X25) and make them not move in the direction they are bumping. I can do collision for 1 block, but how would I do this for all 200?

Hi,
I don't think we needed all that code to try and answer the question at the bottom...
I once did multi-object collision by drawing everything in a hidden bitmap, using:
- two colors only (empty and filled);
- reduced resolution (if everything is a multiple of 25, then divide all coordinates by 25).
In such a bitmap you can detect possible moves and collisions before you apply them to the
"real world". You may want to use more than two colors, say one for empty and one for each
of the objects, that way you know immediately with which object you are going to collide.
Final remark: it does not have to be a real Bitmap and GDI+ operations, you could simply use a
two-dimensional array and manipulate the "pixels" yourself, removing a rectangular object
is a simple clear in two nested fors, adding it at a (slightly) different position is similar.
Collision detection can be handled by just peeking at the intended new positions of the
leading edges.
BTW: nevertheless I like to do it in a paintable way, and for debugging purposes I have
a checkbox that chooses to show either the real world or the simulated world, at the same
location on screen (rescaled to undo the reduced resolution); doing so any bugs become
noticeable right away.

Does GDI and such apply fo XNA?
And thank you for your reply, even if I have some trouble with it.
Another Possible Way?:
Is there a way to check collisions with all of the StaticBlocks with a for loop with good performance results? I tried something like this, but the framerate dipped to around 10...

I don't know. Anyway, I told you you don't really need GDI+, a 2D array and some simple loops
is sufficient.
Furthermore if XNA does not support GDI+, it must have another way to create and operate on
bitmaps without showing them all the time.

Typically you'd store your scene data in a quadtree setup which would let you pick out all the StaticBlocks that are relevant to your player (in the same region). Then its fairly trivial to check if two squares will intersect...

Hi, I have run into a small problem reading text from a file.
Consider this line below as part of the source file.
(Code 1956, § 486.01)
I'm using the good old Streamreader to read the file.
string line = sourceStreamReader.ReadLine();
When this line executes on the above source line the "Section" character " §" is read as char 65533.
I've declare the streamreader as follows.
<br />
StreamReader sourceStreamReader = new StreamReader(sourceFiles[i].ToString());<br />
System.Diagnostics.Debug.WriteLine(sourceStreamReader.CurrentEncoding.EncodingName);<br />
the output from the debug line tells me thats its UTF-8 encoding, but the "section" character is not read nor writes as its original value.
Can someone please tell me where I went wrong!
Just because we can; does not mean we should.

As it turns out, changing the code to the listing below resolved my issue.
<br />
FileStream fStream = File.OpenRead(sourceFiles[i].ToString());<br />
byte[] buffer = new byte[fStream.Length];<br />
int bytesRead;<br />
bytesRead = fStream.Read(buffer, 0, buffer.Length);<br />
<br />
<br />
fStream.Close();<br />
Decoder decoder = Encoding.Default.GetDecoder();<br />
char[] cBuffer = new char[buffer.Length];<br />
int bytesConverted, charsConverted;<br />
bool bCompleted;<br />
<br />
decoder.Convert(buffer, 0, buffer.Length, cBuffer, 0, buffer.Length, false, out bytesConverted, out charsConverted, out bCompleted);<br />
Just because we can; does not mean we should.

That means that the file is not at all Unicode, but ANSI.

Ouch. You read from the file, but you ignore the result. The Read method doesn't have to read as much data as you request. You have to loop until all data is read, or the method return zero.
The easiest is of course to just replace all that code with:
string text = File.ReadAllText(sourceFiles[i].ToString(), Encoding.Default);
Despite everything, the person most likely to be fooling you next is yourself.

Hi all,
Any one suggest me how to get a file from a folder using the partial file name. It's similar to wildcard search in database.
For eg:
in my folder there are files with following name.
sample_text.txt, sample_data.txt,samplefile,data_text.txt
in the above files i have to get the file list which name starts with sample_ like this.
is it possible to do this using regular expression?
Please suggest me
Thanks in advance

Use the System.IO.Directory.GetFiles() method. Set your search expression to 'sample_*.*'.

Thank you very much for your replay. I tried the above suggestion. But it returning me Illegal Charter path error.
My sample code:
string filenamesss = Directory.GetFiles("c:\\samplefiles\\20*.pdf");

Try this if the documentation you read does not make it clear. BTW, Directory.GetFiles returns a string array!
string[] filenamesss = Directory.GetFiles("c:\\samplefiles\\", "*.PDF", System.IO.SearchOption.TopDirectoryOnly);
OR
<br />
string[] filenamesss = Directory.GetFiles("c:\\samplefiles\\", "*.PDF", System.IO.SearchOption.AllDirectories);
Just because we can; does not mean we should.

Is it possible to create static extension methods in the latest .Net framework? I presently have the following scenario:
I have a bottom level project, call it Base, that defines some objects that
are common accross multiple solution files (lets use UInt128 as an example)
I have a Web Service API project, call it WebAPI, that only contains a web reference
I have a main project file, call it Main, that has a reference to both Base and WebAPIThe problem is that WebAPI contains a class, WebAPI.UInt128, that is logically equivalent to Base.UInt128. Now, I want to add an explicit operator to case a WebAPI.UInt128 into a Base.UInt128 and back. Since neither the WebAPI nor the Base projects have a reference to both types, I wanted to define this operator in the place that makes the most sence, which is within the Main project. Is there some way to do this? Thanks in advance,
Sounds like somebody's got a case of the Mondays

Yes with framework 3.5 you can create extension methods. Although I would think it better to define it in base and have WebAPI use that reference. Creating a class with the same name in different namespaces, with presumably different functionality will lead to confusing code that is difficult to maintain.

I actually don't create two different classes with the same name... Visual Studio does it for me. Basically, the WebAPI.UInt128 only contains the serialized data from within the Base.UInt128 class, even though both are logically equivalent. However, since the WebAPI is automatically generated and in actuallity does not depend on Base, I should not need to add that reference to the WebAPI project. For a client that DOES have access to both WebAPI and Base, that client should be able to use either UInt128 class interchangeably. That is why I asked for such a thing.

Could you please provide an example of how I would declare the following from within the Main project? I am having a hard time finding any documentation describing how to externally define static extension methods.
public static explicit operator WebAPI.UInt128(Base.UInt128 other) { ... }Thanks,
