Problem with add listview items

[mark108]

Hi guys,

I need your help. I am using managed c++/cli to code for my project. I know how to add the listview items by extact the data from the website. Now I just want to know how I can do the autosearch in the textbox to search the actual items in the listview?

I have tried this:

using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace System::Net;
using namespace System::Text::RegularExpressions;
using namespace System::IO;
using namespace System::Text;
using namespace System::Web;
using namespace System::Configuration;
using namespace System::Collections::Generic;
using namespace System::Runtime::InteropServices;

private:
	bool isMatch(ListViewItem ^lvi)
	{
		return lvi->Text->StartsWith(TextBox1->Text);
	}

private: System::Void TextBox1_TextChanged(System::Object^ sender, System::EventArgs^ e) {

			Random ^r = gcnew Random();
			List<ListViewItem^> ^items = gcnew List<ListViewItem^>();
			array<ListViewItem^> ^filteredItems = Array::FindAll(items->ToArray(), gcnew System::Predicate<ListViewItem^>(this, &Form2::isMatch));
			ListView1->Items->Clear();
			ListView1->Items->AddRange(filteredItems);
		 }

private: System::Void timer1_Tick(System::Object^ sender, System::EventArgs^ e) {

			 MessageBox::Show("timer starts now");
			 timer1->Enabled = false;
			 Form2 ^form7 = gcnew Form2();

			 try
			 {
				 //Address of URL
				 String ^URL = "http://www.mysite.com/login.php?user=" + form2->ComboBox1->Text + "&pass=" + form2->TextBox1->Text;
				 HttpWebRequest ^request = safe_cast<HttpWebRequest^>(WebRequest::Create(URL));
				 HttpWebResponse ^response = safe_cast<HttpWebResponse^>(request->GetResponse());
				 StreamReader ^reader = gcnew StreamReader(response->GetResponseStream());
				 String ^str = reader->ReadToEnd();

				 String ^pattern1 = "(<p id='myid1'>(.*?)</p>)";
				 MatchCollection ^matches1 = Regex::Matches(str, pattern1);

				Random ^r = gcnew Random();
				List<ListViewItem^> ^items = gcnew List<ListViewItem^>();

				 for each (Match ^x1 in matches1)
				 {
		 array<String^> ^StrArr1 = x1->Value->ToString()->Split();
		 items->Add(gcnew ListViewItem(gcnew array<String^> {x1->Value->ToString()->Replace("<p id='myid1'>", "")->Replace("</p>", "")}));
				 }
				 ListView1->Items->AddRange(items->ToArray());
			 }
			 catch (Exception ^ex)
			 {
				 MessageBox::Show("the site you request is down!");
			 }
		 }

It doesn't work. None of the listview items have been adding in the listview.

Do you know what the problem is?



Any advice would be much appreicate.

Thanks,
Mark

Does anyone know how to do this?

I can barely read it, much less fix it, but you might repost this in the .NET programmer area if no one here can help. Sorry but managed code just isnt c++, they changed so much its a new language.

I moved it to the .NET section so reposting isn't necessary.
