my program running on background makes my current open application in desktop to blink blink such excel , google, outlook etc.

[User 12776818]

Hi All, I create a program that runs on backgound using VB.NET minicap.exe with CMD as process. Inside the code is module and SUB_MAIN with system timers. It works fine except i notice that when my program runs on background as process? The other application on desktop is BLINKING intermittently. the system timer is set to 2sec upto 10seconds. heres my code below. The main purpose of my program is to capture screenshot of desktop and save to network drive using MINICAP.EXE and CMD and SYSTEM TIMERS.

Imports System.Timers
Imports Microsoft.Win32
Imports MySql.Data.MySqlClient

Module Module1
Private myTimer1 As Timer
Private myTimer2 As Timer
Private myTimer3 As Timer
Private WithEvents MyProcess As Process
Private Delegate Sub AppendOutputTextDelegate(ByVal text As String)

Sub main()


    DBconnection()

    Dim uname As String
    Dim mname As String
    Dim Yourpath As String


    uname = Environment.UserName
    mname = Environment.MachineName

    Try
        Dim squery As String = "Select \* from tbl\_settings WHERE Computer = '" & mname & "'"
        Dim sadapter As New MySqlDataAdapter
        Dim scommand As New MySqlCommand
        Dim sqltable As New DataTable
        Dim i As Integer
        Dim PAT
        Dim STAT
        Dim INTR
        Dim COMPR
        Dim x As Integer
        With scommand
            .CommandText = squery
            .Connection = myconnection
        End With
        With sadapter
            .SelectCommand = scommand
            .Fill(sqltable)
        End With

        x = sqltable.Rows.Count
        STAT = IIf(sqltable.Rows(i)("Status") IsNot DBNull.Value, sqltable.Rows(i)("Status"), vbNullChar)
        If STAT = "ON" Then


            COMPR = IIf(sqltable.Rows(i)("Compression") IsNot DBNull.Value, sqltable.Rows(i)("Compression"), vbNullChar)
            INTR = IIf(sqltable.Rows(i)("Interval") IsNot DBNull.Value, sqltable.Rows(i)("Interval"), vbNullChar)
            PAT = IIf(sqltable.Rows(i)("server\_path") IsNot DBNull.Value, sqltable.Rows(i)("server\_path"), vbNullChar)


            'InputTextBox.Text = "minicap.exe -capturedesktop -stderr -noerr -cursor -compress" & " " & CAP & " " & "-exit -save" & " " & PAT

If you are capturing images of the screen at regular intervals then you must expect some disruption to the screen display.

I understand that loading of mouse cursor is normal every interval but interacting with other windows form or programs is not.

On a slower PC, the "blink" may become more visible; my PC isn't a very fast one, but running on a high resolution - you'd be saving a large blob every so often. So no, the spyware isn't going to work.

I dont save it as blob. You can check the minicap.exe by donation coader. it saves directly to shared drive. loading of a mouse cursor if fine. but the main problem is the Windows form is intermittently loosing focus and focusing on minimized forms.
