Debug.Write

What is the difference between Debug.Write and Debug.WriteLine?

Debug.WriteLine displays each result in a new line while Debug.Write displays all the results on one line without spaces.

Back to Top

Debug.WriteLine

Purpose:

Is used to display a message in the Output window while a procedure is being processed by the computer. If the message is a container, the contents thereof will be displayed.

Syntax:

Debug.WriteLine(message)

message: can be a literal constant, e.g. "Hello" or "5"

can be the name of a variable, object or constant, e.g sngSales, objTextBox, conTax

Example:

To display the contents of the variable sngNumber in the Output window

Debug.WriteLine(sngNumber)

Back to Top

Focus

Allows you to shift the focus to a specified control (make an inactive control active) while the program is running.

Syntax:

	[Me.]object.Focus()
	Me.	Optional, refers to a form-level object
	object	Is the name of the control object, e.g a button, to which you want to give focus
	Focus	Method name

Back to Top

SelectAll

Is used to select (highlight) all the text contained in a textbox. Text will only be selected if the textbox has the focus, so use it in conjunction with the Focus method for best results.

Syntax:

	[Me.]textbox.SelectAll()
	Me.	Optional, refers to a form-level object
	textbox	Is the name of the textbox where the text appears that you wish to select (highlight)
	SelectAll	Method name

Back to Top

SetBounds

Is used to change the location and/or size of a control while the program is running.

Syntax:

control.SetBounds(x, y, width, height, specified)
control	Is the name of the control object, e.g a button, whose size/location you want to change
SetBounds	Method name
x	Specifies the location of the left edge of the control on the Windows Form - a zero value means no change	Together they are referred to as the Location
y	Specifies the location of the top edge of the control on the Windows Form - a zero value means no change	Together they are referred to as the Location

width	Sets the width of the control - a zero value means no change	Together they are referred to as the Size
height	Sets the height of the control - a zero value means no change	Together they are referred to as the Size
specified	Is an intrinsic constant that specifies the arguments in the method (see the Arguments list below).

Arguments list:

BoundsSpecified.None	- No arguments are specified
BoundsSpecified.All	- All arguments are specified
BoundsSpecified.Location	- Both X and Y arguments are specified
BoundsSpecified.Size	- Both width and height arguments are specified
BoundsSpecified.X	- Specifies left argument
BoundsSpecified.Y	- Specifies top argument
BoundsSpecified.Width	- Specifies width argument
BoundsSpecified.Height	- Specifies height argument

Tips:

*	The values contained in the x, y, width and height elements can be numerical variables, e.g intValue or numerical constants, e.g conMove or plain numbers, e.g 6.
*	Arguments can be used in conjunction with logical operators, e.g "BoundsSpecified.X Or BoundsSpecified.Width" or "BoundsSpecified.Y AndElse BoundsSpecified.Height"

Examples:

Notice the effect of using two different arguments for the same statement:

Me.FruitPictureBox.SetBounds(35, 60, 0, 0, BoundsSpecified.Location) -- The picturebox is placed 35 pixels from the left edge of the form and 60 pixels from the top edge of the form, but the size remains unchanged

Me.FruitPictureBox.SetBounds(35, 60, 0, 0, BoundsSpecified.All) -- The picturebox is placed 35 pixels from the left edge of the form and 60 pixels from the top edge of the form. The width and height is adjusted to zero pixels

Using a numerical variable in the SetBounds method:

The counter (intCount) in the For...Next loop controls the value of the x argument (x refers to left) in the SetBounds method. The counter increases with every loop which results in the picturebox's x argument being increased accordingly - the visible effect will be that the picturebox moves 5 pixels away from the left edge of the form with every loop.

Dim intCount As Integer

For intCount = 0 To 275 Step 5

Me.FruitPictureBox.SetBounds(intCount, 0, 0, 0, BoundsSpecified.X)

Next intX
