Read text from Text File

[Nerrazzuri]

Need some help on my NRZBot v2.1

I'm able to copy the texts on every textbox to a .txt file using StreamWriter class but hell I can't retrieve it back to the textbox from the .txt file.

here is the code i use to write to the .txt file

Code: Select all

String^Skill1 = textBox2->Text;
String^Skill2 = textBox3->Text;
String^Skill3 = textBox4->Text;
String^Charge1 = textBox5->Text;
String^Charge2 = textBox6->Text;
String^Charge3 = textBox7->Text;  
String^ValueHP = textBox1->Text;
String^ValueMP = textBox8->Text;
StreamWriter^ sWriter = gcnew StreamWriter("c:\\BotSettings.txt");
sWriter->WriteLine(Skill1);
sWriter->WriteLine(Skill2);
sWriter->WriteLine(Skill3);
sWriter->WriteLine(Charge1);
sWriter->WriteLine(Charge2);
sWriter->WriteLine(Charge3);
sWriter->WriteLine(ValueHP); 
sWriter->WriteLine(ValueMP);
sWriter->Close();

And I've tried to read through some examples on google but return no result. Wish someone who can help me on this.

I'm not using MFC, so im not sure if this can be used.

get the line of the file with ifstream.h into a variable
then SetDlgItemText for that textbox,
then continue getting the next line

hope it helps

I'm not using MFC either, I'm using Windows Form C++/CLI class, so SetDlgItemText doesn't work for me.

for me i will use array

Code: Select all

string^writedata = textBox2->text +";" + textBox3->text + ";" + textBox4->text + ";" + textBox5->text + ";" + textBox6->Text + ";" + textBox7->Text + ";" + textbox1->text + ";" + textBox8->text;
StreamWriter SR = gcnew StreamWriter("C:\\settings.txt");
SR->Write(writedata);
SR->dispose();

for reading,use this

Code: Select all

Streamreader^SR = gcnew StreamReader("C:\\Settings.txt");
string[]^readdata = SR->Readtoend->Split(";");
textBox2->text = string[0]->tostring();
textBox3->Text = string[1]->ToString();
//blablabla

NOte:you can use \n to spllit the data u wrote using streamwriter

Instead of using your codes, this is mine.

Code: Select all

String^ delimiter = ";";
String^ fileName = "c:\\Settings.txt";
StreamReader^ sr = gcnew StreamReader(fileName);

			try
			{
				while (sr->Peek() >= 0)
				{
					String^ r = sr->ReadLine();
					array<String^>^ items = r->Split(delimiter->ToCharArray());
				}
			}
			finally
			{
				sr->Close();
			}

Ok, got rid of that error. Still it doesn't re-write it back into my textBox. Clueless. >.<

I can't, I have no idea how to write it back into the textbox from the text file. :S
