I'm working on an Inno Setup installer, which calls net use to connect to a shared server. The installer can connect to the server, if it's running on Windows XP, but not on Windows 7. I think it's related to UAC as I type the same command, the server is connected on Windows 7, but the setup is running with admin privileges.
I'm using the following net use command through Exec or ShellExec script functions:
/c net use \\servername password /user:username
Actually, here is a part of the script showing the net use command call:
[Code]
var
ErrorCode: Integer;
cmdString: String;
intvalue: Integer;
str: String;
function InitializeSetup(): Boolean;
begin
cmdString := '/c net use \\servername password /USER:username';
ShellExec('', ExpandConstant('{cmd}'), cmdString , '', SW_SHOWNORMAL,
ewWaitUntilTerminated, ErrorCode)
if (ErrorCode = 0) then
begin
MsgBox(ExpandConstant('{cmd}'), mbInformation, MB_OK);
end;
end;
Can anybody suggest how to use net use from Inno Setup on Windows 7? We just want to connect to a server and let user input name and password.
Thank you!
How to connect to a remote resource invoking the credentials dialog?
Using a different view on your question, which is actually as the title of this answer says, I'd suggest you to use the WNetUseConnection function call with CONNECT_INTERACTIVE and CONNECT_PROMPT flags. That will in combination with empty user ID and password parameters invoke the credentials dialog (and that's what you wanted). In Inno Setup script it may look like this:
[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program
[Code]

#else
#define AW "A"

I need to get a fully qualified domain name for a Windows machine on a domain in Delphi.
I've tried to use LookupAccountSid but it gives me only the netbios domain name,
in my case it is "intranet" but I need the full "intranet.companyname.com"
Any Ideas?
Try the GetUserNameEx Windows API function.
const
NameUnknown = 0;
NameFullyQualifiedDN = 1;
NameSamCompatible = 2;
NameDisplay = 3;
NameUniqueId = 6;
NameCanonical = 7;
NameUserPrincipal = 8;
NameCanonicalEx = 9;
NameServicePrincipal = 10;
NameDnsDomain = 12;
function GetUserNameExString(ANameFormat: DWORD): string;
var
Buf: array[0..256] of Char;
BufSize: DWORD;
GetUserNameEx: function (NameFormat: DWORD; lpNameBuffer: LPSTR;
var nSize: ULONG): BOOL; stdcall;
begin
Result := '';
BufSize := SizeOf(Buf) div SizeOf(Buf[0]);
GetUserNameEx := GetProcAddress(GetModuleHandle('secur32.dll'), 'GetUserNameExA');
if Assigned(GetUserNameEx) then
if GetUserNameEx(ANameFormat, Buf, BufSize) then
Result := Buf;
end;
using the NameDnsDomain format for example, will result www.mydomain.com\user_name if you are logged into "www.mydomain.com" domain.
Since I now implemented this for my own needs in our application, #iPath's comment was quit right. better use GetComputerNameEx, and specify one of the COMPUTER_NAME_FORMAT for your own needs.
A Delphi implementation would look like this (Unicode version):
interface
...
type
COMPUTER_NAME_FORMAT = (
ComputerNameNetBIOS,
ComputerNameDnsHostname,
ComputerNameDnsDomain,
ComputerNameDnsFullyQualified,
ComputerNamePhysicalNetBIOS,
ComputerNamePhysicalDnsHostname,
ComputerNamePhysicalDnsDomain,
ComputerNamePhysicalDnsFullyQualified,
ComputerNameMax);
function GetComputerNameExString(ANameFormat: COMPUTER_NAME_FORMAT): WideString;
implementation
...
function GetComputerNameExW(NameType: COMPUTER_NAME_FORMAT; lpBuffer: LPWSTR;
var nSize: DWORD): BOOL; stdcall; external kernel32 name 'GetComputerNameExW';
function GetComputerNameExString(ANameFormat: COMPUTER_NAME_FORMAT): WideString;
var
nSize: DWORD;
begin
nSize := 1024;
SetLength(Result, nSize);
if GetComputerNameExW(ANameFormat, PWideChar(Result), nSize) then
SetLength(Result, nSize)
else
Result := '';
end;
NetGetJoinInformation should work fine.
MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa370423(v=vs.85).aspx
Example:
type
PWKSTA_INFO_100 = ^WKSTA_INFO_100;
WKSTA_INFO_100 = packed record
wki100_platform_id: DWord;
wki100_computername: PWChar;
wki100_langroup: PWChar;
wki100_ver_major: DWord;
wki100_ver_minor: DWord;
end;
TNetSetupJoinStatus =
(
NetSetupUnknownStatus,
NetSetupUnjoined,
NetSetupWorkgroupName,
NetSetupDomainName
);
TNetApiBufferFreeFunction = function(ABuffer: Pointer): DWORD; stdcall;
TNetWkstaGetInfoFunction = function(const AServername: PWChar; const ALevel: DWord; const ABufptr: Pointer): DWORD; stdcall;
TNetGetJoinInformationFunction = function(const AServerName: PWChar; out ANameBuffer: PWChar; out ABufferType: TNetSetupJoinStatus): DWORD; stdcall;
const
NERR_SUCCESS = 0;
function GetLocalComputerDomainName: string;
var
NetApiBuffer: Pointer;
NetApi: THandle;
NetApiBufferFree: TNetApiBufferFreeFunction;
NetWkstaGetInfo: TNetWkstaGetInfoFunction;
NetGetJoinInformation: TNetGetJoinInformationFunction;
NetSetupJoinStatus: TNetSetupJoinStatus;
NameBuffer: PWideChar;
begin
Result := '';
NetApi := LoadLibrary('netapi32.dll');
if NetApi <> 0 then
begin
NetApiBufferFree := TNetApiBufferFreeFunction( GetProcAddress(NetApi, 'NetApiBufferFree'));
NetGetJoinInformation := TNetGetJoinInformationFunction(GetProcAddress(NetApi, 'NetGetJoinInformation'));
NetWkstaGetInfo := TNetWkstaGetInfoFunction( GetProcAddress(NetApi, 'NetWkstaGetInfo'));
if #NetApiBufferFree <> nil then
begin
if #NetSetupJoinStatus <> nil then
begin
if NetGetJoinInformation(nil, NameBuffer, NetSetupJoinStatus) = NERR_SUCCESS then
begin
if NetSetupJoinStatus = NetSetupDomainName then
begin
Result := NameBuffer;
end;
NetApiBufferFree(NameBuffer);
end;
end;
end;
FreeLibrary(NetApi);
end;
end;
I tried all of the above, but without success. In the end, I settled for simply grabbing the environment variable.
uses jclSysInfo;
function GetDomain:string;
begin
result:=GetEnvironmentVariable('USERDNSDOMAIN');
end;
Tested on Server 2008 R2 - works fine. Returns "server.home.lan".
Results in an empty string on a Windows 7 non-domain connected PC.
The only correct api to use is DsGetDcName.
Because NetGetJoinInformation is still from the 'lanmanager age' so, the domain is LM compliant.
The code here is C, but you are smart enough to do the same in Delphi :)
PDOMAIN_CONTROLLER_INFOW pdomInfo ;
auto result1 = ::DsGetDcNameW(nullptr, nullptr, nullptr, nullptr, DS_DIRECTORY_SERVICE_PREFERRED | DS_RETURN_DNS_NAME, &pdomInfo);
if (result1 == ERROR_SUCCESS) {
auto retVal = SysAllocString(pdomInfo->DomainName);
::NetApiBufferFree(pdomInfo);
}

CoInternetIsFeatureEnabled in Delphi2010
Does anyone know how to stop the clicking sound. That doesn't appear to work in Delphi XE when I drop it into a separate pas file. There is some missing . and other reasons why it wont compile so im a bit stuck.
Here's what I did.
unit untUrlMon;

CoInternetSetFeatureEnabled(FEATURE_DISABLE_NAVIGATION_SOUNDS, SET_FEATURE_ON_PROCESS, True);
end;
I'd imagine you need something like this:
unit untUrlMon;
implementation
uses
Windows;
const
SET_FEATURE_ON_PROCESS = $00000002;
FEATURE_DISABLE_NAVIGATION_SOUNDS = 21;
function CoInternetSetFeatureEnabled(FeatureEntry: DWORD; dwFlags: DWORD; fEnable: BOOL): HRESULT; stdcall; external 'urlmon.dll';
initialization
CoInternetSetFeatureEnabled(FEATURE_DISABLE_NAVIGATION_SOUNDS, SET_FEATURE_ON_PROCESS, True);
end.
If you replace the final "end;" with "end." it should compile.
I believe you also need ";" after the two function declarations (after the "external 'urlmon.dll'" part).
The final "begin/end" is then run automatically in every program you include this unit in.
So I just got an answer to my question about getting the Skype Chatbox handle.
I am now trying to create a simple function, that digs for a handle. Here is how I am hoping to be able to use it:
MyHWND := DigForHandle(['Notepad','Edit'],['Untitled - Notepad','']);
Params:
1) Array of String: Holds the Class Hierachy.
2) Array of String: Holds the Window Caption Hierachy.
As you see, the 2nd entry in the 2nd parameter is empty, since the Edit Class does not have a Window Caption.
Would it be possible to create such function? :)
Try this
uses
Windows, Messages, TlHelp32, SysUtils;
type
PGetWindowParam = ^TGetWindowParam;
TGetWindowParam = record
ProcID: DWORD;
WindowCaption: string;
Result: HWND;
end;

TempExeFileName: string;
begin
Result := 0;
SnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if SnapshotHandle <> 0 then
begin
FillChar(ProcessEntry32, SizeOf(ProcessEntry32), 0);
ProcessEntry32.dwSize := Sizeof(ProcessEntry32);
ContinueLoop := Process32First(SnapshotHandle, ProcessEntry32);
while ContinueLoop do
begin
TempExeFileName := ExtractFileName(ProcessEntry32.szExeFile);
if SameText(TempExeFileName, ExeFileName) then
begin
Result := ProcessEntry32.th32ProcessID;
Break;
end;
ContinueLoop := Process32Next(SnapshotHandle, ProcessEntry32);
end;
CloseHandle(SnapshotHandle);
end;
end;
function GetWindow(Wnd: HWND; P: LParam): BOOL; stdcall;
var

begin
Result := True; // assume it doesn't match; keep searching
Param := PGetWindowParam(P);
ProcID := 0;
GetWindowThreadProcessID(Wnd, #ProcID);
if ProcID <> Param^.ProcID then
Exit;
FillChar(WindowTitle, SizeOf(WindowTitle), 0);
if SendMessage(Wnd, WM_GETTEXT, SizeOf(WindowTitle) - SizeOf(Char), LPARAM(#WindowTitle[0])) <= 0 then
Exit;
if AnsiSameStr(WindowTitle, Param^.WindowCaption) then
begin
Param^.Result := Wnd;
Result := False;
end;
end;
function DigForHandle(const ProcName, Caption: string; const Hierachy: array of string): HWND;
var
Param: TGetWindowParam;
I: Integer;
ParentWnd: HWND;
begin
Result := 0;
FillChar(Param, SizeOf(Param), 0);
Param.ProcID := FindPID(ProcName);
if Param.ProcID = 0 then
Exit;
Param.Result := 0;
Param.WindowCaption := Caption;
EnumWindows(#GetWindow, LPARAM(#Param));
if Param.Result = 0 then
Exit;
I := 0;
ParentWnd := Param.Result;
while (ParentWnd <> 0) and (I < Length(Hierachy)) do
begin
Param.Result := 0;
Param.WindowCaption := Hierachy[I];
EnumChildWindows(ParentWnd, #GetWindow, LPARAM(#Param));
if Param.Result = 0 then
Break;
ParentWnd := Param.Result;
Inc(I);
end;
if I >= Length(Hierachy) then
Result := Param.Result;
end;
When I thought about it, I realized that it was actually rather simple - the code I had though, was "confusing" for me, which was why I asked a question here. After trying it out, I found that doing it this way, its a lot easier to read, and not as complicated (IMO).
Function DigForHandle(ClassHierachy, TextHierachy : Array of String):HWND;
Var
Handle : HWND;
I : Integer;
PClass,PText : PChar;
Begin
Result := 0;
I := 0;
while (I <= Length(ClassHierachy)-1) do
begin
PClass := PChar(ClassHierachy[I]);
PText := PChar(TextHierachy[I]);
if PClass = '' then PClass := Nil;
if PText = '' then PText := Nil;
Result := FindWindowEx(Result,0,PClass,PText);
Inc(I);
end;
End;
Using the standard win32 api, what's the best way to detect more than one user is logged on? I have an upgrade to our software product that can't be run when more than one user is logged in. (I know this is something to be avoided because of its annoyance factor, but the product is very complicated. You'll have to trust me when I say there really is no other solution.) Thanks.
In order to have more than one user logged in at once, Terminal Services or Fast User Switching must be enabled. Since Fast User Switching is implemented using Terminal Services, you first need to find out if the OS has it enabled. You can use GetVersionEx with an OSVERSIONINFOEX. Check for the VER_SUITE_SINGLEUSERTS and VER_SUITE_TERMINAL flags.
If TS is enabled, you can use WTSEnumerateSessions to find out how many users are logged on. This only works if the "Terminal Services" service is started.
If the machine doesn't support Terminal Services (or if the service isn't started), then you can only have one user logged on.
Here's a solution that works on XP, Server 2003, Vista, and Server 2008. Note, this won't work on Windows 2000, because "LsaEnumerateLogonSessions" is not available on Windows 2000. This code is modified from a Delphi-PRAXIS post.
To compile this, create a new VCL application with a TButton and a TMemo on the form. Then copy and paste this code and it should compile. I tested on XP and Vista and it works well. It will return interactive and remote users.

This might be a roundabout way, but run down the process list and see who the process owners are.
