Building detours with the VS 2008 compiler and 6.1/Server 2008 SDK

ben — Tue, 23 Sep 2008 23:43:57 +0000

There are a couple of potential problems you may run into when trying to build detours using the VS 2008 SDK 6.1 tools and headers:

on an x64 system the make file will default to building for x64, which is disabled in the free version. To build for x64 you must get a license from Microsoft for $10000 — most likely you just want to build the x86 version though. You can configure building to x86 by setting an environment variable:
```
set DETOURS_TARGET_PROCESSOR=x86
```
your lib and include paths might not be set correctly, I recommend setting both to first the SDKs directory, then the VS directory like:
```
set lib=C:\Program Files\Microsoft SDKs\Windows\v6.1\Lib;C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib
```
```
 
```
```
set include=C:\Program Files\Microsoft SDKs\Windows\v6.1\Include;C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include
```

When you do a “nmake all” now, detours itself should build, but the compilation of the samples will abort with an error:

symtest.cpp(270) : error C2664: 'BOOL (HANDLE,PSYM_ENUMMODULES_CALLBACK64,PVOID)' :

 cannot convert parameter 2 from 'overloaded-function' to 'PSYM_ENUMMODULES_CALLBACK64'

of the functions with this name in scope match the target type

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\cl.EXE"' :

 return code 0x2'

Stop.

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\nmake.exe"' : return code '0x2'

Stop.

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\nmake.exe"' : return code '0x2'

Stop.

Austin Donnelly has posted a patch for this problem, you’ll need to patch two files, first samples/findfunc/symtest.cpp:

After you applied those two patches, “nmake all” should successfully build detours and all the samples.

MSI setup: how to do a sql server connection test

bschwehn — Tue, 16 Oct 2007 19:27:12 +0000

The WiX (Windows Installer XML) toolset is a collection of open source tools that assists the creation of MSI installations.
It includes a collection of custom actions that (among other things) allow including a sql database setup in your installation.
Setting up a database is quite simple:

DropOnReinstall="no" Server="[SQLSERVERNAME]" Database ="[SQLSERVERDATABASENAME]">

Note that the server and database name are variables. They are filled in by the user during the GUI part of the installation.

Unfortunately, no custom action is provided that would allow you to do a connection test before actually executing the sql custom action. If the user makes a typo, the custom action will fail at install time and the entire installation is rolled back.

As this is not really acceptable, I’ve written a C++ custom action that does a connection test. With this custom action I can test the user provided credentials before the actual installation starts – and provide feedback if the credentials are incorrect.

Using the code and libraries that come with WiX, writing the custom action was really quite simple:

#include

#include

#include

#include "wcautil.h"

#include "dutil.h"

#include "sqlutil.h"

#include "strutil.h"

void ReleaseString(LPWSTR psz) {

if(psz) {

StrFree(psz);

extern "C" UINT __stdcall CheckSqlConnection(MSIHANDLE hInstall) {

LPWSTR pszDbName = NULL;

LPWSTR pszServerName = NULL;

LPWSTR pszUserName = NULL;

LPWSTR pszAuthentificationMode = NULL;

LPWSTR pszPassword = NULL;

BOOL integratedMode = FALSE;

HRESULT hr = WcaInitialize(hInstall, "CheckSqlConnection");

ExitOnFailure(hr, "Failed to initialize");

hr = WcaSetProperty(L"SQLCONNECTIONTESTRESULT", L"Not checked");

ExitOnFailure(hr, "Failed to set property");

hr = WcaGetProperty(L"SQLSERVERDATABASENAME", &pszDbName);

ExitOnFailure(hr, "Failed to get property");

hr = WcaGetProperty(L"SQLSERVERNAME", &pszServerName);

ExitOnFailure(hr, "Failed to get property");

hr = WcaGetProperty(L"SQLSERVERUSERNAME", &pszUserName);

ExitOnFailure(hr, "Failed to get property");

hr = WcaGetProperty(L"SQLSERVERAUTHENTIFICATIONMODE", &pszAuthentificationMode);

ExitOnFailure(hr, "Failed to get property");

integratedMode = wcscmp(pszAuthentificationMode, L"1") == 0;

hr = WcaGetProperty(L"SQLSERVERPASSWORD", &pszPassword);

ExitOnFailure(hr, "Failed to get property");

IDBCreateSession* sessionId;

hr = SqlConnectDatabase(pszServerName, L"", L"master", integratedMode, pszUserName, pszPassword, &sessionId);

if (hr == ERROR_SUCCESS) {

hr = WcaSetProperty(L"SQLCONNECTIONTESTRESULT", L"1");

ExitOnFailure(hr, "Failed to set property");

else {

hr = WcaSetProperty(L"SQLCONNECTIONTESTRESULT", L"0");

ExitOnFailure(hr, "Failed to set property");

LExit:

ReleaseString(pszDbName);

ReleaseString(pszServerName);

ReleaseString(pszUserName);

ReleaseString(pszAuthentificationMode);

ReleaseString(pszPassword);

return WcaFinalize(hr);

You have to export the CheckSqlConnection method (e.g. by using an exports.def file) and link with msi.lbi (comes with the windows sdk) and the WiX libraries dutil.lib and wcautil.lib.

In my setup GUI I’ve included a dialog that allows entering the sql credentials and do a connection test (note: SharpDevelop comes with a handy GUI designer for WiX)

generate create assembly from <binary bits> script

bschwehn — Sun, 07 Oct 2007 21:06:32 +0000

Just a quick’n'dirty powershell script to generate the t-sql create assemby statement for creating a clr assembly. Converts the dll to the corresponding <assembly_bits> binary values like:

create assembly [TestAssembly] from 0×4D5A90 [...]

Useful when you just want to have a sql script and don’t want to bother copying or otherwise making the dll accessible to the database server.
I use it for building in a makefile target.

param

$out = 'createAssembly.txt',

$assemblyFile = 'TheDll.dll',

$assemblyName = 'TestAssembly'

$stringBuilder = New-Object -Type System.Text.StringBuilder

$stringBuilder.Append("create assembly [") > $null

$stringBuilder.Append($assemblyName) > $null

$stringBuilder.Append("] from `n0x") > $null

$assemblyFile = resolve-path $assemblyFile

$fileStream = [IO.File]::OpenRead($assemblyFile)

while (($byte = $fileStream.ReadByte()) -gt -1) {

$stringBuilder.Append($byte.ToString("X2")) > $null

$stringBuilder.Append("`nwith permission_set = SAFE")

$stringBuilder.ToString() > $out;

$fileStream.Close()

$fileStream.Dispose()
