Instead of StreamReader, you can use File.ReadAllText(path) and for return type of the function, you can make its return type to string instead of void. Is the programming language c++, unfortunately I am not proficient in it.

i finally found a way to read two files and put into the function private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { Pen^ blackpen = gcnew Pen(System::Drawing::Color::Black, 3); OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog; StreamReader^ srMQB ; StreamReader^ srCANTrace; String^ xm; String^ xc; std::string MQB,CANTrace ; if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)//to open a dialog box { srMQB = gcnew StreamReader(openFileDialog1->FileName);//read the file xm = Convert::ToString(srMQB); MQB = msclr::interop::marshal_as (xm); } OpenFileDialog^ openFileDialog2 = gcnew OpenFileDialog; if (openFileDialog2->ShowDialog() == System::Windows::Forms::DialogResult::OK)//to open a dialog box { srCANTrace = gcnew StreamReader(openFileDialog2->FileName);//read the file xc = Convert::ToString(srCANTrace); CANTrace = msclr::interop::marshal_as (xc); } data->Read_CAN_file(MQB, CANTrace); } now i want the output of that function to be displayed in richtextbox

Sorry, I couldn't able to understand your question. Are you asking to read files through openfiledialog and show the output to richtextbox? Please elaborate your question properly

sure but i need to convert from string to streamstring, because in the function it accept file in string but while reading through button click event i use streamreader, can you tell me the method to convert OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog; StreamReader^ srMQB ; StreamReader^ srCANTrace; String^ MQB; if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)//to open a dialog box { srMQB = gcnew StreamReader(openFileDialog1->FileName);//read the file } OpenFileDialog^ openFileDialog2 = gcnew OpenFileDialog; if (openFileDialog2->ShowDialog() == System::Windows::Forms::DialogResult::OK)//to open a dialog box { srCANTrace = gcnew StreamReader(openFileDialog2->FileName);//read the file } data->Read_CAN_file(srMQB, srCANTrace);
