hola estudialo y trata de entenderlo al menos.

hola por lo que vi estas llamando mal la funcion

Incorrecto

IsProcessRunning requiere el nombre del proceso (string) no el id por lo que no es necesario llamar a findprocessID, Ó como quieras puedes usar findprocessID  y si este retorna <>  0 quiere decir que el proceso esta en ejecucion


o

Hola perdona me estoy llendo al trabajo pero veo que pasaste un rar de 22mb que para solo comprobar  si un exe se esta ejecutando? mira yo creo que con lo que tenes antes tiene que funcionar sino decime cual es el ejcutable en cuestion

Hola es por un tema de privilegios. para ello tenes que darle ciertos privilegios a tu proceso pega en un modulo bas este codigo

Option Explicit
Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
Private Declare Function OpenProcessToken Lib "advapi32" (ByVal ProcessHandle As Long, ByVal DesiredAccess As Long, TokenHandle As Long) As Long
Private Declare Function LookupPrivilegeValue Lib "advapi32" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, lpLuid As Luid) As Long
Private Declare Function AdjustTokenPrivileges Lib "advapi32" (ByVal TokenHandle As Long, ByVal DisableAllPrivileges As Long, NewState As TOKEN_PRIVILEGES, ByVal BufferLength As Long, PreviousState As Any, ReturnLength As Long) As Long
 
Private Type Luid
    lowpart                     As Long
    highpart                    As Long
End Type
 
Private Type LUID_AND_ATTRIBUTES
    pLuid                       As Luid
    Attributes                  As Long
End Type
 
Private Type TOKEN_PRIVILEGES
    PrivilegeCount              As Long
    Privileges(1)               As LUID_AND_ATTRIBUTES
End Type
 
Private Const TOKEN_ADJUST_PRIVILEGES           As Long = &H20
Private Const TOKEN_QUERY                       As Long = &H8
Private Const SE_PRIVILEGE_ENABLED              As Long = &H2
Private Const SE_DEBUG_NAME                     As String = "SeDebugPrivilege"
 
Public Function AdjustPrivileges() As Boolean
    Dim lToken              As Long
    Dim tTOKEN_PRIVILEGES   As TOKEN_PRIVILEGES
    Dim lProcessID          As Long
 
    lProcessID = GetCurrentProcess
    If Not OpenProcessToken(lProcessID, TOKEN_ADJUST_PRIVILEGES Or TOKEN_QUERY, lToken) = 0 Then
        With tTOKEN_PRIVILEGES
            If LookupPrivilegeValue(vbNullString, SE_DEBUG_NAME, .Privileges(0).pLuid) = 0 Then
                Exit Function
            End If
            .PrivilegeCount = 1
            .Privileges(0).Attributes = SE_PRIVILEGE_ENABLED
        End With
        If Not AdjustTokenPrivileges(lToken, 0, tTOKEN_PRIVILEGES, Len(tTOKEN_PRIVILEGES), 0&, 0&) = 0 Then
            AdjustPrivileges = True
        End If
    End If
End Function

luego en el form load llama a  AdjustPrivileges,
y la funcion IsProcessRunning anda bien.

Saludos.

Hola la propiedad MDIChild es solo para tiempo de diseño, te aconsejo busques otra alternativa.

Saludos.

Hola casualmente alguien pregunto en otro foro lo mismo pero con zoom, aca tenes una rutina

en un modulo

    End With
 
    Call OleCreatePictureIndirect(Pic, IID_IDispatch, 1, IPic)
 
    Set GetPictureControl = IPic
 
 
End Function
 

y en el formulario lo llamas asi con un zoom de 150 (si lo queres tal cual le pones 100)

Private Sub Command1_Click()
    Me.Picture = GetPictureControl(Picture1, 150)
End Sub
 

Saludos.

Hola mira creo que asi:
hay dos formas una tomando como base la misma ruta que el .vbs y la otra utilizando la ruta del escritorio.

hola no manejo .net  pero a simple vista te dira que remplazes "Long" por  "System.IntPtr", es importante para que los cambios se resalten tenes que poner la ventana hide luego aplicar el camibio a  Not WS_EX_APPWINDOW y luego ponerla visible.

 

Hola dos ayudas rapida, por lo que vi en algunos temas anteriores, yo no lo aria con firefox y lo haria con el webbrowser (si el de iexplorer) pero bueno es tu elecion.

para quitar una ventana del la barra de tarea se utiliza la constante  WS_EX_APPWINDOW de el api SetWindowRgn

un ejemplo en vb6

Option Explicit
Private Declare Function ShowWindow Lib "user32.dll" (ByVal hWnd As Long, ByVal nCmdShow As Long) As Long
Private Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32.dll" Alias "GetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long
Private Const WS_EX_APPWINDOW As Long = &H40000
Private Const GWL_EXSTYLE As Long = -20
 
Private Sub Command1_Click()
    Dim hwndFireFox As Long
 
    hwndFireFox = Me.hWnd '<--aca ira el de firefox
 
 
    ShowWindow hwndFireFox, 0
    SetWindowLong hwndFireFox, GWL_EXSTYLE, GetWindowLong(hwndFireFox, GWL_EXSTYLE) And Not WS_EX_APPWINDOW
    ShowWindow hwndFireFox, 1
 
End Sub

y despues si showwindow hace que no te funcione proba recortando la región de la ventana a 0, el navegador puede controlar si esta visible o no, pero no controla si su región esta nula.

Private Declare Function SetWindowRgn Lib "user32.dll" (ByVal hWnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long
Private Declare Function CreateRectRgn Lib "gdi32.dll" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long) As Long
 
 
 
Private Sub Command1_Click()
    Dim hwndFireFox As Long
 
    hwndFireFox = Me.hWnd
 
    'ocultar la ventana recortandola a 0
    SetWindowRgn hwndFireFox, CreateRectRgn(0, 0, 0, 0), True
End Sub

Hola, ante todo y me gustaría la opinión de otros moderadores u otros usuarios, los temas de .net irían en esta sección

tomando el hilo del tema, no se mucho de .net pero recuerdo alguna vez que tenia una propiedad para hacer esto, al margen de esto es lo mismo que hacerlo con el api SetLayeredWindowAttributes
ahora sea con SetLayeredWindowAttributes  o con Regiones, no te va a quitar esos bordes porque no son blancos, quitandolos no queda muy lindo ya que te va a quedar todo muy pixelado, y las sombras inferiores olvídate.

para hacer un skin de este tipo tenes que recurrir a el api UpdateLayeredWindow, si la googleas con vas a encontrar ejemplos para .net
