Creating the Visit Form

The final part of the three-part minuet is to create the Visit form from within the larger .NET application. A "real" Visit form might include a lot of data, and sophisticated search tools to pick the patient, the new diagnosis, and the appropriate medications. To keep things simple, we'll just use drop-downs to identify the patient and the new diagnosis, as shown in Figure 5.

Figure 5. New visit

Once the patient name and the new diagnosis have been added, new medications can be added as shown in Figure 6.

Figure 6. Add Rx.

That done, specific notes for the visit may be added, as shown in Figure 7.

Clicking Discard will discard all these changes (and the new diagnosis and medications for the user will not be recorded). You might want to pop up an "Are you sure?" dialog!

Clicking Save will save the new visit, the new diagnosis, and any new prescriptions to the database, and will create the new personalized Word document for mailing to the patient. Let's examine the Save code in some detail. Here it is in full (analysis follows):

private void btnSave_Click(object sender, EventArgs e)
{
    Cursor = Cursors.WaitCursor;

    // gather data 
    int patientID = Convert.ToInt32(patientsComboBox.SelectedValue);
    string patientName = 
        ((System.Data.DataRowView)(patientsComboBox.SelectedItem)).Row.ItemArray[1].ToString();
    int diagnosisID = Convert.ToInt32(diagnosesComboBox.SelectedValue);
    string diagnosisString = 
        ((System.Data.DataRowView)(diagnosesComboBox.SelectedItem)).Row.ItemArray[1].ToString();

    //** update the database **

    // update the visit table
    this.visitsTableAdapter.InsertVisit(visitTime, txtNotes.Text, patientID);

    // update the Diagnosis table
    this.patientToDiagnosesTableAdapter.InsertPatientToDiagnosis(patientID, diagnosisID);

    // add the new meds
    string newMeds = string.Empty;
    foreach (MedicationHolder holder in lbMeds.Items)
    {
        newMeds += holder.MedName + ", ";
        int numAdded = this.patientToMedicationTableAdapter.InsertNewPatientMedication(
            patientID, holder.MedID, visitTime);
        if (numAdded != 1)
        {
            MessageBox.Show("Unable to add " + holder.MedName, "Uh oh",
                MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
        else
        {
            this.patientToMedicationTableAdapter.InsertNewPatientMedication(
                patientID, holder.MedID, visitTime);
        }
