Aug 4th, 2008
Hello all,
I have overloading method problem with my miniproject. The code is below :
C# Syntax (Toggle Plain Text) 
  1. patients.UpdatePatientsDetail(patientsidTextBox.Text, patientsnameLabel1.Text);

Error is : no overload for UpdatePatientsDetail takes '2' arguments
Code for this method is :
C# Syntax (Toggle Plain Text) 
  1.  public void UpdatePatientsDetail(string strPatientsID, string strPatientsName, string strPatientsAddress, string strPatientsTelephonenumber, string strPatientsDateofBirth, string strPatientsNric, string strPatientsEmailAdress, string strPatientsApponitmentTime)
  2.         {
  3.             string SQL;
  4.             SQL = "UPDATE Patients SET PatientsName = '" + strPatientsName +
  5.                 "', PatientsAddress = '" + strPatientsAddress +
  6.                 "', PatientsTelephonenumber = '" + strPatientsTelephonenumber +
  7.                 "', PatientsDateofBirth = '" + strPatientsDateofBirth + 
  8.                 "', PatientsNric = '" + strPatientsNric +
  9.                 "', PatientsEmailAdress = '" + strPatientsEmailAdress +
  10.                 "', PatientsAppointmentTime = '" + strPatientsApponitmentTime +
  11.                 "' where PatientsID = " + strPatientsID + "";
  12.             ExecuteDataCommand(SQL);
  13.         }

I can't fix the error. Any help will be appreciated. Thank you.

Your method takes 8 parameters, and you are trying to call it with just two params. Either give it all 8 or override the UpdatePatientDetails() to take 2 parameters
===========================
can you repeat the part of the stuff where you said all about the things?

Thank you for your reply.
I still got error can't overload the method.
C# Syntax (Toggle Plain Text) 
  1.  consu.UpdateConsultationDetail(consultationidTextBox.Text, consultationdateTextBox.Text, patientspastillnessComboBox.Items.Add, patientspastdiagnosisComboBox.Items.Add, patientscurrentillnessTextBox.Text, patientscurrentdiagnosisComboBox.Items.Add);

The method is below :
C# Syntax (Toggle Plain Text) 
  1.  
  2. public void UpdateConsultationDetail(string strConsultationID, string strDiagnosis, string strConsultationDate, string strPatientsPastIllness, string strPatientsCurrentIllness, string strPatientsPastDiagnosis, string strPatientsCurrentDiagnosis)
  3.         {
  4.             string SQL;
  5.             SQL = "UPDATE Consultation SET ConsultationDate = '" + strConsultationDate +
  6.                 "', PatientsPastIllness = '" + strPatientsPastIllness +
  7.                 "', PatientsPastDiagnosis = '" + strPatientsPastDiagnosis +
  8.                 "', PatientsCurrentDiagnosis = '" + strPatientsCurrentDiagnosis +
  9.                 "', PatientsCurrentIllness = '" + strPatientsCurrentIllness +
  10.                 "' where ConsultationID = " + strConsultationID + "";
  11.             ExecuteDataCommand(SQL);
  12.         }

How to fix it? I passed enough parameters but still got error. Thanks.

I think you passed the wrong parameters.

•
•
•
•
patientspastillnessComboBox.Items.Add
patientspastdiagnosisComboBox.Items.Add,
patientscurrentdiagnosisComboBox.Items.Add
is it the String above three parameters?

As I knew, those means that the event.

The parameters declare are strings, but those are all combobox and I want to pass all the content of combobox into the method. So now what should I do?

That's easy way here.

Your method :

•
•
•
•
consu.UpdateConsultationDetail(consultationidTextBox.Text, consultationdateTextBox.Text, patientspastillnessComboBox.Items.Add, patientspastdiagnosisComboBox.Items.Add, patientscurrentillnessTextBox.Text, patientscurrentdiagnosisComboBox.Items.Add);
changed into:

consu.UpdateConsultationDetail(consultationidTextBox.Text, consultationdateTextBox.Text, patientspastillnessComboBox, patientspastdiagnosisComboBox, patientscurrentillnessTextBox.Text, patientscurrentdiagnosisComboBox);

after doing this,

you can choose items in CheckBox in the method by

(String)patientspastillnessComboBox.Items[INDEX_NUM]; // INDEX_NUM: 0 ~ n(existed item number)

I hope this reply help you.

Change the code of all combobox.

from:
patientspastdiagnosisComboBox.Items.Add

to:
patientspastdiagnosisComboBox.SelectedItem.ToString()
