'1-) Inicie um novo projeto no VB e inclua um módulo no seu projeto. inclua o seguinte código no módulo:
Public Type STARTUPINFO
cb As Long
lpReserved As String
lpDesktop As String
lpTitle As String
dwX As Long
dwY As Long
dwXSize As Long
dwYSize As Long
dwXCountChars As Long
dwYCountChars As Long
dwFillAttribute As Long
dwFlags As Long
wShowWindow As Integer
cbReserved2 As Integer
lpReserved2 As Long
hStdInput As Long
hStdOutput As Long
hStdError As Long
End Type
Public Type PROCESS_INFORMATION
hProcess As Long
hThread As Long
dwProcessID As Long
dwThreadID As Long
End Type
Public Declare Function WaitForSingleObject Lib _
"kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds _
As Long) As Long
Declare Function CreateProcessA Lib "kernel32" _
(ByVal lpApplicationName As Long, ByVal lpCommandLine As _
String, ByVal lpProcessAttributes As Long, ByVal _
lpThreadAttributes As Long, ByVal bInheritHandles As Long, _
ByVal dwCreationFlags As Long, ByVal lpEnvironment As Long, _
ByVal lpCurrentDirectory As Long, lpStartupInfo As _
STARTUPINFO, lpProcessInformation As PROCESS_INFORMATION) _
As Long
Declare Function CloseHandle Lib "kernel32" (ByVal hObject _
As Long) As Long
Public Const NORMAL_PRIORITY_CLASS = &H20&
Public Const INFINITE = -1&
'2-) A seguir insira o seguinte código em um formulário padrão:
Public Sub ExecCmd(cmdline$)
Dim proc As PROCESS_INFORMATION
Dim start As STARTUPINFO
'Inicia a strutura STARTUPINFO
start.cb = Len(start)
'Inicia a aplicação escolhida para ser executada
ret& = CreateProcessA(0&, cmdline$, 0&, 0&, 1&, _
NORMAL_PRIORITY_CLASS, 0&, 0&, start, proc)
'Aguarda a aplicação iniciada terminar
ret& = WaitForSingleObject(proc.hProcess, INFINITE)
ret& = CloseHandle(proc.hProcess)
End Sub
'3-) Agora adicione um botão de comando - command1 - ao formulário e no evento click do botão digite o seguinte código:
Private Sub Command1_Click()
MsgBox "Vou iniciar o programa"
Call ExecCmd("E:ProgramaMyMeuPrograma.exe")
End Sub
'O código acima irá executar o programa MeuPrograma.exe. Você executa o programa através da função ExecCmd informando o nome e local do aplicativo que quer executar...
