 Delphi的TService 服务路径获取 Dll中获取文件路径
研究delphi服务的路径，试了好几个方法 ，都没取出来，最后发现，要采用取DLL路径的方法

//一、获取Dll自身路径

//1)方法一：

Function GetDllPath（sDllName:string):string;

var
ModuleFileName:array[0..255] of char; 

begin
//{取得dll的实际位置}
GetModuleFileName(GetModuleHandle(sDllName), @ModuleFileName[0], SizeOf(ModuleFileName));
Result := ModuleFileName;
end;

//2)方法二：

Function GetDllPath:string;

var
ModuleName:string;
begin
SetLength(ModuleName, 255);
//取得Dll自身路径
GetModuleFileName(HInstance, PChar(ModuleName), Length(ModuleName));
Result := PChar(ModuleName);

end;


// 二、获取调用程序路径

Function GetExecutPath:string;

var
ModuleName:string;
begin
SetLength(ModuleName, 255);
//取得调用Dll程序的路径
GetModuleFileName(GetModuleHandle(nil), PChar(ModuleName), Length(ModuleName));
Result := PChar(ModuleName);

end;

Delphi遍历进程并获取进程路径

获得进程可执行文件的路径： GetModuleFileNameEx， GetProcessImageFileName， QueryFullProcessImageName

功能模块改良版：

unit UntModulePath;

interface

uses
Windows, SysUtils, PsAPI;

//获取EXE、Dll模块名称 或 路径
function GetModuleFileNameDef(GetPath: Boolean = True): string;

function GetWindowProcHandle(Wnd: HWND; GetPath: Boolean = True): string;

var
DllPath: string;

implementation

function GetModuleFileNameDef(GetPath: Boolean = True): string;
var
ModuleName: array [0..MAX_PATH - 1]of Char;
begin
FillChar(ModuleName, Length(ModuleName), 0);
//取得Dll自身路径
GetModuleFileName(HInstance, ModuleName, Length(ModuleName));

if GetPath then
Result := ExtractFilePath(StrPas(ModuleName))
else
Result := StrPas(ModuleName);
end;


function GetWindowProcHandle(Wnd: HWND; GetPath: Boolean = True): string;
var
pID: Cardinal;
hProc: THandle;
ModuleName: array [0..MAX_PATH - 1]of Char;
begin 
Result := '';
if Wnd= 0 then
Exit;

FillChar(ModuleName, Length(ModuleName), 0);

GetWindowThreadProcessId(Wnd, pID);
hProc:= OpenProcess(PROCESS_QUERY_INFORMATION or PROCESS_VM_READ, False, pID);
if hProc= 0 then
Exit;
try
GetModuleFileNameEx(hProc, 0, ModuleName, Length(ModuleName));
finally
CloseHandle(hProc);
end;
if GetPath then
Result := ExtractFilePath(StrPas(ModuleName))
else
Result := StrPas(ModuleName);
end;

initialization
DllPath:= GetModuleFileNameDef;

end.
