Form Closing Event private void Form2_FormClosing(object sender, FormClosingEventArgs e) { if (MessageBox.Show(“Are you sure?”, “Warning”, MessageBoxButtons.YesNo) == DialogResult.Yes) { e.Cancel = false; } else { e.Cancel = true; } } Note: sender ? object that triggers the event; e ? event argument that provides actions so that handle the event. MessageBox MessageBox.Show(message) MessageBox.Show(message, Caption) MessageBox.Show(message, Caption, Buttons) Note: 1. In each format, arguments are positional in addition to required. 2. This object returns a DialogResult data type. Possible values in consideration of a DialogResult data type are: Abort, Cancel, Ignore, No, None, OK, ReTry, in addition to Yes. To test the return value: Dim ReturnVal as DialogResult ReturnVal=MessageBox(?hello?, ?.) If ReturnVal=DialogResult.OK? Text Box Useful properties BackColor, BorderStyle ReadOnly Enable Visible Password Character Multiline ScrollBar Text Useful events TextChanged: default event Validating ? useful in consideration of validating data entered in the box

Input Validation Numbers are checked so that ensure they are: Within a range of possible values Reasonableness Not causing problems such as division by 0. Containing only digits IsNumeric Texts are checked so that ensure correct format. Phone #, SSN. Required field Textbox: Set CauseValidation property so that true. Use the Validating event: Triggered just before the focus shifts so that other control. Data Entered in Textbox1 Must Be between 10 in addition to 30 private void textBox1_Validating(object sender, CancelEventArgs e) { double enteredData; enteredData = double.Parse(textBox1.Text); if (enteredData30) { MessageBox.Show(“Pls enter a number between 10 in addition to 30”); e.Cancel=true; } } Testing in consideration of digits only This example uses the Double.Parse method trying so that convert the data entered in the box so that double. If fail then it is not numeric. private void textBox1_Validating(object sender, CancelEventArgs e) { try { double.Parse(textBox1.Text); e.Cancel = false; } catch { e.Cancel = true; MessageBox.Show(“Enter digits only”); } } Note: VB has an IsNumeric function in addition to Excel has an ISNumber function.

Things your mother never told you about antibiotics Objectives Common misconceptions/distortions about antibiotics 1. ?Let?s just throw in some antibiotics-it can?t hurt?? 1. The Problem? 2. Clindamycin above the diaphragm, metronidazole below the diaphragm? 2. The Problem? 3. With the high prevalence of MRSA, Vancomycin should be used in consideration of all severe Staph infections? 3. Why not? 4. Osteomyelitis should be treated in consideration of 6 weeks alongside IV antibiotics? 4. Not necessarily? 5. I don?t feel comfortable changing from the empiric regimen because the patient is doing well? 5. Let me help you alongside this? 6. I know the organisms are sensitive so that the antibiotics but the patient?s not getting better? 6. Why? UTI Cases SIMPLE CYSTITIS UTI-2 A 65-year-old man alongside BPH has 2 days of fever, rigors, vomiting, in addition to severe left flank pain.

String Methods ToUpper, ToLower Length ? Number of characters TrimStart, TrimEnd, Trim Substring(Start), Substring(Start, length) IndexOf(SearchString), IndexOf(SearchString, Start) 0 based index Case-sensitive eName=?David? Position=eName.IndexOf(?d?) Return ?1 if the searchString is not found. Note: Text property of a Textbox has all the string methods. Ex. TextBox1.Text.Substring(0,2) Extract First Name in addition to Last Name from Full Name in this format: FirstName LastName int indexSpace; string firstName, lastName ; indexSpace = textBox2.Text.IndexOf(” “); firstName = textBox2.Text.Substring(0, indexSpace); lastName = textBox2.Text.Substring(indexSpace + 1); MessageBox.Show(firstName); MessageBox.Show(lastName); Group Box It is a container control. Controls in a Group Box should move alongside the box.

Radio Button Radio buttons must be grouped together inside a container such as a GroupBox or a form. When the user selects an option all other options in the same group are deselected. Properties: Checked: True/False. Default button: Set the Checked property so that true at the design time. Events: CheckedChanged Example private void button1_Click(object sender, EventArgs e) { if (radioButton1.Checked) MessageBox.Show(“Button 1 checked”); else if (radioButton2.Checked) MessageBox.Show(“Button 2 checked”); else MessageBox.Show(“Button 3 checked”); } Tuition Rules For undergraduate: If total units <= 12, then tuition = 1200; Otherwise, tuition = 1200 + 200 per additional unit For graduate: If total units <= 9, then tuition = 1500; Otherwise, tuition = 1500 + 400 per additional unit Nested Decision Structures You can create nested decision structures so that test more than one condition. Nested means ?one inside another? In C#, a generic format is: if (expression) { if (expression) { statements; } else { statements; } } else { statements } private void button1_Click(object sender, EventArgs e) { double units, tuition; units=double.Parse(textBox1.Text); if (radioButton1.Checked) { if (units <= 12) tuition = 1200; else tuition = 1200 + 200 * (units - 12); } else { if (units <= 9) tuition = 1500; else tuition = 1500 + 400 * (units - 9); } } Check Box Check boxes do not belong so that a group even when they are grouped in a Group Box. Checked property in addition to checkedChanged event Which CheckBoxes are cheked? private void button1_Click(object sender, EventArgs e) { string box=""; if (checkBox1.Checked) box += "box1"; if (checkBox2.Checked) box += "box2"; if (checkBox3.Checked) box += "box3"; MessageBox.Show(box); } Note: Cannot use if-else-if Rules in consideration of Discount If total sales is greater than 1000, then the customer will get a 10% discount ; otherwise, the customer will get a 5% discount. If the customer is a club member, then applies 20% off the discounted charges. private void button1_Click(object sender, EventArgs e) { try { double totalSales, discountRate, netPay; string myMsg; totalSales = double.Parse(textBox1.Text); if (totalSales <= 1000) discountRate = .05; else discountRate = .1; netPay = totalSales * (1 - discountRate); if (checkBox1.Checked) netPay = netPay * (1 - .20); textBox2.Text = netPay.ToString("C"); } catch (Exception ex) { MessageBox.Show(ex.Message); } } List Box Useful properties Items: The items in the listBox. It is a collection strcture. Items can be entered at the design time or entered in code. 0-based index SelectionMode: one or multi selection SelectedItem SelectedIndex Methods Add Clear Event: SelectedIndexChange ListBox Items Collections Methods: ADD: ListBox1.Items.Add("Apple") Item: Retrieve an object from Items ListBox1.Items.Item(Index) or ListBox1.Items(Index) 0-based index Insert: ListBox.Items.Insert(Index, item) Remove: Delete an object alongside a position index or key. ListBox.Items.Remove(Item) ListBox.Items.RemoveAt(Index) Clear: ListBox.Items.Clear() Count: Return the number of objects in a collection. ListBox.Items.Count Adding Items Using Code private void Form11_Load(object sender, EventArgs e) { listBox1.Items.Add("Apple"); listBox1.Items.Add("Orange"); listBox1.Items.Add("Banana"); listBox1.Items.Add("Strawberry"); listBox1.Items.Add("Kiwi"); } private void listBox1_SelectedIndexChanged(object sender, EventArgs e) { MessageBox.Show(listBox1.SelectedItem.ToString()); MessageBox.Show(listBox1.SelectedIndex.ToString()); } Working alongside Radiobuttons, Listbox Create a form alongside 2 radiobuttons. When radiobutton1 is selected, populate a listbox alongside fruit names.; otherwise populate the listbox alongside vegetable names. Then, dsplay the fruit or vegetable?s name in a textbox when user select an item from the listbox. Create a Loan Payment Form The switch Statement The switch statement lets the value of a variable or an expression determine which path of execution the program will take It is a multiple-alternative decision structure It can be used as an alternative so that an if-else-if statement that tests the same variable or expression in consideration of several different values Generic Format of switch Statement swtich (testExpression) { case value_1: statements; break; case value_2: statements; break; ? case value_n: statements; break; default: statements; break; } The testExpression is a variable or an expression that given an integer, string, or bool value. Yet, it cannot be a floating-point or decimal value. Each case is an individual subsection containing one or more statements, followed by a break statement The default section is optional in addition to is designed in consideration of a situation that the testExpression will not match alongside any of the case Sample switch Statement switch (month) { case 1: MessageBox.Show(?January?); break; case 2: MessageBox.Show(?February?); break; case 3: MessageBox.Show(?March?); break; default: MessageBox.Show(?Error: Invalid month?); break; } Using VB.Net?s PMT Function Add a reference so that Microsoft Visual Baisc From the Solution Explorer, right-click the References node, then click Add Reference From the .Net tab, select Microsoft Visual Baisc Add this code so that the form: using Microsoft.VisualBasic; ComboBox Allows the user so that type text directly into the combo box. Use the Text property so that get entered item: ComboBox1.Text The index in consideration of an entered item is ?1. Search an item in the list: ComboBox1.Items.IndexOf(?search text?) Found: return the index of the search text. Not found: return ?1. How so that add an entered item so that the list? Timer Properties: Enabled must set so that True. Interval Tick Event private void timer1_Tick(object sender, EventArgs e) { textBox1.Text = System.DateTime.Now.ToString(); } Use a Timer so that Close a Form int counter = 0; private void timer1_Tick(object sender, EventArgs e) { counter+=1; if (counter > 50) { this.Close(); } }
