Hi again.
Is there any method powerfull than sendmessage or closewindow, to make a window close itself.Thank you.
what do you mean by more powerful?
Use the PostMessage api function.
Another way would be to use the CloseHandle api function (this way, you can close a program by knowing it's file path).Code:Declare Function FindWindow Lib "user32" Alias _
"FindWindowA" (ByVal lpClassName As String, _
ByVal lpWindowName As String) As Long
Declare Function PostMessage Lib "user32" Alias _
"PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
ByVal wParam As Long, lParam As Any) As Long
Public Const WM_CLOSE = &H10
Dim winHwnd As Long
Dim RetVal As Long
winHwnd = FindWindow(vbNullString, "Calculator")
Debug.Print winHwnd
If winHwnd <> 0 Then
RetVal = PostMessage(winHwnd, WM_CLOSE, 0&, 0&)
If RetVal = 0 Then
MsgBox "Error posting message."
End If
Else
MsgBox "The Calculator is not open."
End If
Code:Declare Function ProcessFirst Lib "kernel32" Alias "Process32First" (ByVal hSnapshot As Long, uProcess As PROCESSENTRY32) As Long
Declare Function ProcessNext Lib "kernel32" Alias "Process32Next" (ByVal hSnapshot As Long, uProcess As PROCESSENTRY32) As Long
Declare Function CreateToolhelpSnapshot Lib "kernel32" Alias "CreateToolhelp32Snapshot" (ByVal lFlags As Long, lProcessID As Long) As Long
Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szexeFile As String * MAX_PATH
End Type
Public Function KillApp(myName As String) As Boolean
Const PROCESS_ALL_ACCESS = 0
Dim uProcess As PROCESSENTRY32
Dim rProcessFound As Long
Dim hSnapshot As Long
Dim szExename As String
Dim exitCode As Long
Dim myProcess As Long
Dim AppKill As Boolean
Dim appCount As Integer
Dim i As Integer
On Local Error GoTo Finish
appCount = 0
Const TH32CS_SNAPPROCESS As Long = 2&
uProcess.dwSize = Len(uProcess)
hSnapshot = CreateToolhelpSnapshot(TH32CS_SNAPPROCESS, 0&)
rProcessFound = ProcessFirst(hSnapshot, uProcess)
Do While rProcessFound
i = InStr(1, uProcess.szexeFile, Chr(0))
szExename = LCase$(Left$(uProcess.szexeFile, i - 1))
If Right$(szExename, Len(myName)) = LCase$(myName) Then
KillApp = True
appCount = appCount + 1
myProcess = OpenProcess(PROCESS_ALL_ACCESS, False, uProcess.th32ProcessID)
AppKill = TerminateProcess(myProcess, exitCode)
Call CloseHandle(myProcess)
End If
rProcessFound = ProcessNext(hSnapshot, uProcess)
Loop
Call CloseHandle(hSnapshot)
Finish:
End Function
Usage:
Call KillApp("C:\Windows\Calc.exe")
Numibesi: CloseWindow will only minimize the window, not close it.
Also, PostMessage and SendMessage are exactly the same (neither is more 'powerful' than the other) except for the fact that PostMessage returns instantly whereas SendMessage does not.
Thak´s.
I could´t use the find window bacause the form caption changes every time it open´s.But i found a way, i saw that it just opens after an hour so i made a program that when it runs opens the other program and 59 min lather close it again and 2 min lather reopen´s it, so that popup never apears.
