Step 1
OnCreate Event
Answer
To begin, you will need to read the heading from the panel and assign it to a variable. This can be done using the following code:
Dim heading As String
heading = pnl01_1.Text
Next, modify the heading by using the relevant string functions:
- Append a dash (-) to the end of the string and the current date:
heading = heading & " - " & Format(Date, "yyyy/mm/dd")
- Convert the entire heading to uppercase:
heading = UCase(heading)
- Change the font style to bold:
pnl01_1.Font.Bold = True
- Finally, write the updated heading back to the panel:
pnl01_1.Text = heading
Step 2
Button [1.2 - Display]
Answer
To set up the button functionality, use the loop to output the characters from Z to R by implementing an unconditional loop:
Dim sOutput As String
Dim cCounter As Integer
sOutput = ""
For cCounter = Asc("Z") To Asc("R") Step -1
sOutput &= Chr(cCounter)
Next
TextBox1.Text = sOutput
Step 3
Button [1.3.1 - Total number of words]
Answer
To calculate the total number of words:
- Declare an integer variable:
Dim numPages As Integer
- Read the number of pages from the spin edit:
numPages = spinEdit.Value
- Calculate the total words:
Dim totalWords As Integer
totalWords = numPages * WordsPerPage
Step 4
Radio group [1.3.2 - Type of book]
Answer
For determining the read time based on the type of book, follow these steps:
- Determine the type of book selected:
Dim timeInMinutes As Integer
If radioLiterature.Checked Then
timeInMinutes = totalWords / (250)
Else
timeInMinutes = totalWords / (75)
End If
- Display the time in the edit box:
editTimeMinutes.Text = timeInMinutes
Step 5
Combo box [cmb01_4]
Answer
To handle the password decryption:
- Declare necessary variables:
Dim password As String
Dim decryptedPassword As String
- Read the selected password from the combo box:
password = cmb01_4.SelectedItem
- Move the first two characters:
decryptedPassword = Mid(password, 3) & Left(password, 2)
- Replace the # character if it exists and handle other replacements:
If InStr(password, "#") > 0 Then
decryptedPassword = Replace(decryptedPassword, "#", "$&.")
End If
Step 6
Button [1.5 - Coordinates]
Answer
To calculate and display the (x,y) coordinates:
- Clear the output area:
TextBox2.Clear()
- Display the heading:
TextBox2.Text = "Coordinates" & vbNewLine
- Read x value from edit box:
Dim x As Integer
x = Val(EditX.Text)
- Calculate y using the line formula:
Dim y As Integer
y = 3 * x - 2
- Format and display the output:
TextBox2.Text &= "(x,y) = (" & x & "," & y & ")" & vbNewLine
- Reduce x by 2 and repeat until y <= 0:
Do While y > 0
x = x - 2
y = 3 * x - 2
TextBox2.Text &= "(x,y) = (" & x & "," & y & ")" & vbNewLine
Loop
