Delphi的TService 服務路徑獲取 Dll中獲取文件路徑

研究delphi服務的路徑，試了好幾個方法 ，都沒取出來，最後發現，要採用取DLL路徑的方法

//1、獲取Dll自身路徑

//1)方法一：

Function GetDllPath（sDllName:string):string;

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

begin
//{取得dll的實際位置}
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自身路徑
GetModuleFileName(HInstance, PChar(ModuleName), Length(ModuleName));
Result := PChar(ModuleName);

end;


// 2、獲取調用程序路徑

Function GetExecutPath:string;

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

end;

點擊打開連接

Delphi遍歷進程並獲取進程路徑

得到進程可執行文件的路徑： GetModuleFileNameEx， GetProcessImageFileName， QueryFullProcessImageName

功能模塊改良版：

unit UntModulePath;

interface

uses
Windows, SysUtils, PsAPI;

//獲取EXE、Dll模塊名稱 或 路徑
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自身路徑
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.
