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.
