我需要编辑或替换Inno Setup的About Setup对话框文本中的文本.
这是一张图片：
在互联网上看到我得到这个代码：
[Setup]
AppName=My Program
AppVerName=My Program v 1.5
DefaultDirName={pf}\My Program
OutputDir=.
[Languages]
Name: "default"; MessagesFile: "compiler:Default.isl"
[Files]
Source: CallbackCtrl.dll; Flags: dontcopy
[Code]
type
TWFProc = function(h:hWnd;Msg,wParam,lParam:Longint):Longint;
function CallWindowProc(lpPrevWndFunc: Longint; hWnd: HWND; Msg: UINT; wParam: Longint; lParam: Longint): Longint; external 'CallWindowProcA@user32.dll stdcall';
function SetWindowLong(Wnd: HWnd; Index: Integer; NewLong: Longint): Longint; external 'SetWindowLongA@user32.dll stdcall';
function WrapWFProc(Callback: TWFProc; ParamCount: Integer): Longword; external 'wrapcallbackaddr@files:CallbackCtrl.dll stdcall';
var
OldProc:Longint;
procedure AboutSetupClick;
begin
//Edit your text here
MsgBox('CUSTOM TEXT HERE',mbInformation,MB_OK);
end;
function WFWndProc(h:HWND;Msg,lParam:Longint):Longint;
begin
if (Msg=$112) and (wParam=9999) then begin
Result:=0;
AboutSetupClick;
end else begin
if Msg=$2 then SetWindowLong(WizardForm.Handle,-4,OldProc);
Result:=CallWindowProc(OldProc,h,Msg,lParam);
end;
end;
procedure InitializeWizard;
begin
OldProc:=SetWindowLong(WizardForm.Handle,WrapWFProc(@WFWndProc,4));
end;
似乎工作正常..
但如果我关闭安装程序,我会收到崩溃消息.
我需要帮助来修复此代码或提供更好的示例来更改“关于设置”对话框文本框中的文本.
我使用的DLL.

解决方法
在退出安装应用程序之前,需要将保存的原始Windows过程返回到向导表单.为此,请使用以下内容：
const GWL_WNDPROC = -4; procedure DeinitializeSetup; begin SetWindowLong(WizardForm.Handle,GWL_WNDPROC,OldProc); end;
无论如何,您可以使用更可靠的库来包装回调,即InnoCallback库.我已经对您使用的代码进行了审核,并添加了对Unicode InnoSetup版本的支持,期望使用InnoCallback库：
[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program
OutputDir=userdocs:Inno Setup Examples Output
[Files]
Source: "InnoCallback.dll"; DestDir: "{tmp}"; Flags: dontcopy
[Code]
#ifdef UNICODE
#define AW "W"
#else
#define AW "A"
#endif
const
GWL_WNDPROC = -4;
SC_ABOUTBox = 9999;
WM_SYSCOMMAND = $0112;
type
WPARAM = UINT_PTR;
LPARAM = LongInt;
LRESULT = LongInt;
TWindowProc = function(hwnd: HWND; uMsg: UINT; wParam: WPARAM;
lParam: LPARAM): LRESULT;
function CallWindowProc(lpPrevWndFunc: LongInt; hWnd: HWND; Msg: UINT;
wParam: WPARAM; lParam: LPARAM): LRESULT;
external 'CallWindowProc{#AW}@user32.dll stdcall';
function SetWindowLong(hWnd: HWND; nIndex: Integer;
dwNewLong: LongInt): LongInt;
external 'SetWindowLong{#AW}@user32.dll stdcall';
function WrapWindowProc(Callback: TWindowProc; ParamCount: Integer): LongWord;
external 'wrapcallback@files:InnoCallback.dll stdcall';
var
OldWndProc: LongInt;
procedure ShowAboutBox;
begin
MsgBox('Hello,I''m your about Box!',MB_OK);
end;
function WndProc(hwnd: HWND; uMsg: UINT; wParam: WPARAM;
lParam: LPARAM): LRESULT;
begin
if (uMsg = WM_SYSCOMMAND) and (wParam = SC_ABOUTBox) then
begin
Result := 0;
ShowAboutBox;
end
else
Result := CallWindowProc(OldWndProc,hwnd,uMsg,lParam);
end;
procedure InitializeWizard;
begin
OldWndProc := SetWindowLong(WizardForm.Handle,WrapWindowProc(@WndProc,4));
end;
procedure DeinitializeSetup;
begin
SetWindowLong(WizardForm.Handle,OldWndProc);
end;
