[vbnet]
Shared Function GetDesktopImage(Optional ByVal Width As Integer = 0, Optional ByVal Height As Integer = 0, Optional ByVal ShowCursor As Boolean = True) As Image
Dim W As Integer = Screen.PrimaryScreen.Bounds.Width
Dim H As Integer = Screen.PrimaryScreen.Bounds.Height
Dim DesktopBitmap As New Bitmap(W, H)
Dim g As Graphics = Graphics.FromImage(DesktopBitmap)
g.CopyFromScreen(0, 0, 0, 0, New Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height), CopyPixelOperation.SourceCopy)
If ShowCursor Then Cursors.Default.Draw(g, New Rectangle(Cursor.Position, New Size(32, 32)))
g.Dispose()
If Width = 0 And Height = 0 Then
Image = DesktopBitmap
Return DesktopBitmapElse
Dim ScaledBitmap As Image = DesktopBitmap.GetThumbnailImage(Width, Height, Nothing, IntPtr.Zero)
DesktopBitmap.Dispose()
Image = ScaledBitmap
Return ScaledBitmap
End If
End Function[/vbnet]

<li>Add this code to the timer.<br></li>

[vbnet]
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
TimerCount += 1If TimerCount = 1 And Me.WindowState = FormWindowState.Minimized Then
PictureBox1.Image = GetDesktopImage()End If
If TimerCount = 2 And Me.WindowState = FormWindowState.Minimized Then
Me.WindowState = FormWindowState.Normal
End If
End Sub

[/vbnet]

<li>Add this code to the button.<br></li>

[vbnet]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.WindowState = FormWindowState.Minimized
TimerCount = 0
End Sub

Technology stack and requirements

To run this VB.NET project, you need the following on your development machine:

• Visual Studio 2019 or later. The free Community Edition is enough for building, debugging, and running the project.
• .NET Framework 4.7.2 or higher. Most Windows 10 and 11 systems have it preinstalled through Windows Update.
• MySQL Server 8.0 or MSSQL Express 2019. Choose whichever your capstone panel prefers; both work with VB.NET data adapters.
• MySQL Connector/NET or SqlClient library. Add via NuGet Package Manager inside Visual Studio.
• Crystal Reports (optional). Required only if the project generates printable reports; install the runtime redistributable.

Installing the source code

The download link contains a ZIP archive with the full solution. Extract and set up in five steps:

1. Extract the archive to a folder outside Program Files (avoids permission issues).
2. Open the .sln file in Visual Studio. It loads the full solution with all forms and modules.
3. Restore NuGet packages. Right-click the solution then Restore NuGet Packages if prompted.
4. Import the database. Locate the .sql file in the archive and import via phpMyAdmin (MySQL) or SQL Server Management Studio.
5. Update the connection string in App.config or module code to match your local database name, user, and password.

How to use this project for your BSIT capstone

This VB.NET project maps cleanly to standard BSIT capstone documentation. Suggested chapter alignment:

• Chapter 1 (Introduction). Discuss the problem the system solves in real-world context. Cite Philippine business or academic use cases where a manual process could be replaced.
• Chapter 2 (Review of Related Literature). Compare this system’s features against 5-10 similar published projects. Cite journals like IJERT or IEEE Access for academic-standard sources.
• Chapter 3 (Methodology). Include Use Case Diagram, Data Flow Diagram, Entity Relationship Diagram, and Activity Diagram covering all major workflows in the system.
• Chapter 4 (Results and Discussion). Screenshot each module of the running system with a caption explaining what data it processes and which user role interacts with it.
• Chapter 5 (Conclusion and Recommendations). Identify features that could be added in a Version 2, such as web dashboard, mobile app, or REST API export.

Modules typical of How to Capture Full Screen using VB.Net

• Master data. CRUD forms for the primary entities the system manages, with search and filter.
