حذف نوار عنوان و خصوط حاشیه یک برنامه خارج از برنامه اصلی توسط توابع API

[ROSTAM2]

سلام.
من می خوام نوار عنوان و خطوط حاشیه پنجره یک برنامه خارج از برنامه اصلی مثل Notepad یا یک console app رو با کدهای API حذف کنم.
دستور موجود هیچ تغییراتی روی پنجره ایجاد نمی کنه:

ثابت ها و توابع API:

 Public Const GWL_STYLE As Short = -16

Public Const WS_BORDER = &H800000



    Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long

    Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long

متود سفارشی:

Sub SetWindowBorder(Handle As IntPtr)

        Dim lStyle As Long

        lStyle = GetWindowLong(Handle, GWL_STYLE)

        lStyle = lStyle And Not WS_BORDER

        SetWindowLong(Handle, GWL_STYLE, lStyle)

    End Sub

مشکل از کجاست؟

سلام و روز خوش

در همین منبع اصلی:
pinvoke.net: GetWindowLongPtr (user32)

اومده که برای ویندوز 64 بیت باید از این تابع استفاده کنین.

چون ویرایشگر اینجا کدها رو به هم میریزه کل ماژول رو بعنوان یک فایل پیوست میکنم:

[mazoolagh]

بخش تعریف WindowStyles کلا از اینجا برداشته شده:
pinvoke.net: WindowStyles (Enums)

فقط یک مورد دیگه بهش اضافه کردم:

WS_NOBORDER = Not (WS_BORDER Or WindowStyles.WS_SIZEFRAME)

[mazoolagh]

Public Class Form1 

   Dim WS_original As WindowStyles

    Dim hWnd As IntPtr





    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim prc() As Process = Process.GetProcessesByName("cmd")

        If prc.Length > 0 AndAlso prc(0).MainWindowHandle.ToInt32 > 0 Then

            hWnd = prc(0).MainWindowHandle

            WS_original = GetWindowLongPtr(hWnd, GWL.GWL_STYLE)

            Dim WS_new As WindowStyles = WS_original And WindowStyles.WS_NOBORDER

            SetWindowLongPtr(hWnd, GWL.GWL_STYLE, WS_new)

این ساده ترین حالت هست،
ممکنه لازم باشه شما با توجه به شرایط تعریف دیگه ای برای WS_NOBORDER بنویسین.
یا نیاز باشه که از WindowStylesEx هم استفاده کنین.

سلام.
ممنون برای صدا زدن پروسس به اون صورت جواب می ده اما من ی Console App رو با خود نرم افزار اجرا می کنم همزمان با لود شدن فرم:

    Dim P As Process

    Private Sub MainForm_Load(sender As Object, e As System.EventArgs) Handles Me.Load

        Dim s As ProcessStartInfo = New ProcessStartInfo(Application.StartupPath + "\Console\ConsoleApp.exe")

        With s

            .UseShellExecute = True

            .WorkingDirectory = Application.StartupPath + "\Console"

            .CreateNoWindow = True

            .WindowStyle = ProcessWindowStyle.Maximized

        End With

        P = Process.Start(s)

    End Sub

و در رویداد Shown از فرم دستورات حذف نوار عنوان قرار دادم ولی روی اون app اجرا نمی شه در صورتی که با همین روش توسط کد های api شیء والد برای اون تعیین کردم و درست عمل می کنه.

 

        SetWindowParent(Me.ConsolePanel, P)





Dim WS_original As WindowStyles

        WS_original = GetWindowLong(P.MainWindowHandle, GWL.GWL_STYLE)

        Dim WS_new As WindowStyles = WS_original And WindowStyles.WS_NOBORDER

        SetWindowLong(P.MainWindowHandle, GWL.GWL_STYLE, WS_new)

Untitled.jpg

آیا این دستورات می تونن یک پروسس تعریف شده در خود برنامه رو پشتیبانی کنن یا باید فکر دیگه ای کرد؟!

[mazoolagh]

سلام دوباره
این کد اگر window handle مشخص باشه مشکلی نداره صرفنظر از این که parent اون چی باشه.
فکر کنم وقتی رخداد window shown اجرا میشه هنوز پروسه p کاملا اجرا نشده و بنابراین window handle اون مشخص نیست.
برای اطمینان 2 راه هست:

1- کد رو بجای window shown در یک button click بذارین و نتیجه رو چک کنین.
اگر اجرا شد مشکل همینه

2- در ابتدای رخداد window shown و قبل از کد اصلی، کد زیر رو اضافه کنین و window handle رو چک کنین:

debug.print (p.mainwindowhandle)

اگر 0 باشه مشکل همینه

اگر مشکل همین مشخص نبودن window handle بود کد زیر رو قبل از کد اصلی اضافه کنین - باحتمال زیاد برطرف میشه.

do while p.mainwindowhandle=0

loop
