상위 양식의 중앙 MessageBox
.net 2.0에서 MessageBox를 상위 형태로 중앙에 배치하는 쉬운 방법이 있습니까?
저는 이것이 C#에 꼭 필요했고 Center MessageBox C#을 찾았습니다.
여기 제대로 포맷된 버전이 있습니다.

Joel Spolsky의 블로그 댓글에서:
메시지 상자는 항상 화면 중앙에 있습니다.소유자를 제공할 수 있지만, 이는 Z-order용일 뿐 중심이 아닙니다.유일한 방법은 Win32 후크를 사용하여 직접 중심을 잡는 것입니다.당신이 그것을 검색하면 당신은 온라인에서 그것을 하는 것을 찾을 수 있습니다.
메시지 상자 클래스를 직접 작성하고 센터링 기능을 추가하는 것이 훨씬 쉽습니다.그런 다음 기본 캡션을 추가할 수도 있습니다. 다시 표시 안 함 확인란을 선택하여 모델이 없는 상태로 만들 수도 있습니다.
"Win32hooks"는 아마도 다음을 사용하는 것을 의미할 것입니다.SetWindowsHookEx이 예에서 보듯이.
그러나 MessageBox별 구현을 중단해야 하는 이유는 무엇입니까?아래 클래스를 다음과 같이 사용합니다.
private void OnFormClosing(object sender, FormClosingEventArgs e)
{
DialogResult dg;
using (DialogCenteringService centeringService = new DialogCenteringService(this)) // center message box
{
dg = MessageBox.Show(this, "Are you sure?", "Confirm exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
}
if (dg == DialogResult.No)
{
e.Cancel = true;
}
}
대화 상자 창이 다른 스레드에 의해 소유된 경우에도 대화 상자 창을 표시하는 모든 항목에서 사용할 수 있는 코드(우리 앱에는 여러 UI 스레드가 있음):
다음 코드는 대화 상자가 두 모니터 사이에 중앙에 있지 않거나 부분적으로 화면 밖에 있도록 모니터 작업 영역을 고려한 업데이트된 코드입니다.필요할 것입니다.enum SetWindowPosFlags아래 중)

한번 해보세요, 시간을 정당화할 만큼 충분히 간단합니다.
이것은 C로 작성된 Win32 API용입니다.필요할 때 번역해 보세요...
case WM_NOTIFY:{
HWND X=FindWindow("#32770",NULL);
if(GetParent(X)==H_frame){int Px,Py,Sx,Sy; RECT R1,R2;
GetWindowRect(hwnd,&R1); GetWindowRect(X,&R2);
Sx=R2.right-R2.left,Px=R1.left+(R1.right-R1.left)/2-Sx/2;
Sy=R2.bottom-R2.top,Py=R1.top+(R1.bottom-R1.top)/2-Sy/2;
MoveWindow(X,Px,Py,Sx,Sy,1);
}
} break;
WndProc 코드에 추가...원하는 대로 위치를 설정할 수 있습니다. 이 경우에는 기본 프로그램 창을 중심으로 배치됩니다.모든 메시지 상자, 파일 열기/저장 대화 상자 및 기타 기본 컨트롤에 대해 이 작업을 수행합니다.확실하지는 않지만 COMCTRL 또는 COMMDLG를 포함해야 사용할 수 있을 것 같습니다. 적어도 대화 상자를 열고 저장하려면 사용할 수 있습니다.
저는 NMHDR의 알림 코드와 hwndFrom을 보고 실험을 했습니다. 그리고 나서 그것이 그만큼 효과적이고 훨씬 쉽다고 결정했습니다.매우 구체적으로 설명하려면 찾기 창에서 찾을 창에 제공하는 고유 캡션(제목)을 찾으라고 합니다.
이는 메시지 상자가 화면에 그려지기 전에 실행되므로 코드에서 작업이 수행되는 시기를 나타내는 글로벌 플래그를 설정하고 고유한 캡션을 찾는 경우 수행하는 작업이 한 번만 수행됩니다(알림자가 여러 명 있을 가능성이 높음).이에 대해 자세히 살펴보진 않았지만 CreateWindow를 통해 메시지 상자 대화 상자에 편집 상자를 추가할 수 있었습니다.그것은 복제 돼지의 척추에 이식된 쥐의 귀처럼 어울리지 않는 것처럼 보였지만, 효과가 있었습니다.이런 식으로 일을 처리하는 것이 자신의 일을 처리하는 것보다 훨씬 쉬울 수도 있습니다.
까마귀.
EDIT: 올바른 창을 처리할 수 있도록 작은 수정 작업을 수행합니다.부모 핸들이 전체적으로 일치하는지 확인하십시오. 그러면 이 작업이 제대로 수행됩니다.같은 프로그램의 두 사례를 봐도 그렇습니다.
확실히 배경(디자이너) 코드를 조금 더 많이 사용한다면 자신만의 패널이나 양식을 사용하는 것이 가장 간단한 접근법일 것입니다.사용자 정의 코드를 모두 작성하지 않고 중앙 집중화 및 조작 측면에서 모든 제어를 제공합니다.
