No, cchIniName is initialized, I was just saving everyone an extra chunk of
code that is working. Here is the function that initializes cchIniName and
the other WiX property strings before the call to fopen_s:
// NOTE: Caller responsible for freeing TCHAR * buffer if non-null return
code
TCHAR * __stdcall privMsiGetPropertyStr(MSIHANDLE hInstaller, TCHAR
*strName)
{
TCHAR* szValueBuf = NULL;
DWORD cchValueBuf = 0;
UINT uiStat = ::MsiGetProperty(hInstaller, strName, TEXT(""),
&cchValueBuf);
if (ERROR_MORE_DATA == uiStat)
{
++cchValueBuf; // output count does not include terminating null, so add 1
szValueBuf = new TCHAR[cchValueBuf];
if (szValueBuf)
{
uiStat = MsiGetProperty(hInstaller, strName, szValueBuf, &cchValueBuf);
}
}
if (ERROR_SUCCESS != uiStat)
{
if (szValueBuf != NULL)
delete [] szValueBuf;
return NULL;
}
return szValueBuf;
}
---
I copied that chunk of code from somewhere, excuse the poor use of Hungarian
notation.
If you look at what I am writing to this ".ini" file, you will notice that
it has nothing to do with what a <IniFile> deal with. This is a .ini file
that supplies java startup variable to Eclipse (actually, our customized
version of Eclipse). Eclipse is very touchy and I am afraid to try a
unicode file since it works with a text file. Heck, I wouldn't need this CA
at all if Eclipse could figure out %WINDIR% in a path, but it can't.
As I mentioned, this works GREAT under XP. Though this CA was quickly
hacked together and leaves room for improvement, there is nothing
intrinsically wrong with the CA code. It does what it is supposed to as
long as the directory it is trying to write to exists before it tries to
write the file to it. There is something wrong with the .msi sequencing
that is baffling me, as that directory should exist long before it tries to
execute my custom action.

Your call to fopen_s uses the uninitialised cchIniName buffer as the path
name to open for writing.
(BTW, misuse of Hungarian notation because this is _not_ a Count of
Characters - use sz or psz for string-terminated-with-zero. If that's what
you intended, of course.)
You can also edit INI files using the <IniFile> element which maps to a
native Windows Installer feature. The type of the Value field is Formatted,
so you should be able to substitute property values using [] within the
field data.

fprintf writes to the file pointed to by cchIniName.

Did you miss a line out? You don't appear to have written to the buffer
pointed to by cchIniName so it will be filled with garbage. The success or
failure may depend on whether the junk in the buffer parses as a valid file
name or not.
I would strongly recommend using Unicode file name buffers and therefore
_wfopen_s if you're targetting Windows NT-based operating systems only and
not supporting Windows 9X.

Subject: [WiX-users] Custom Action works under WinXP-SP2, fails under Win2K?
My installer needs to work under WinXP and Win2K for this round. I wrote a
custom action and it works great under WinXP but fails under Win2K and I
cannot figure out why. I am using WiX v3.0.2420, both machines have Windows
R Installer. V 3.01.4000.1823 installed.
The custom action is in a C++ DLL, here is the action function:
UINT __stdcall WriteTSBIni(MSIHANDLE hInstaller)
{
UINT rc = ERROR_SUCCESS;
USES_CONVERSION;
// Get the installation directory name
TCHAR *cchWindowsFolder = privMsiGetPropertyStr(hInstaller,
TEXT("WindowsFolder"));
TCHAR *cchInstallDir = privMsiGetPropertyStr(hInstaller,
TEXT("INSTALLDIR"));
TCHAR *cchIviDir = privMsiGetPropertyStr(hInstaller,
TEXT("IVIDIRPROP"));
if (cchIviDir)
{
if (cchWindowsFolder)
{
if (cchInstallDir)
{
size_t szBuf = strlen(W2CA(cchInstallDir)) +
strlen ("Test Script Builder\\TestScriptBuilder.ini") + 1;
char *cchIniName = new char[szBuf];
FILE *fIni;
if (errno_t err = fopen_s(&fIni, cchIniName, "w"))
{
sprintf_s(cchIniName, szBuf, "err=%d", err);
return ERROR_INSTALL_FAILURE;
}
else
{
fprintf (fIni, "-vmargs\r\n");
fprintf (fIni, "-Djava.lang.path=.;");
fprintf (fIni, "%s.;", W2A(cchIviDir));
fprintf (fIni, "%s.;", W2A(cchWindowsFolder));
fprintf (fIni, "%sSystem32\\.;\r\n",
W2A(cchWindowsFolder));
fclose (fIni);
}
delete[] cchIniName;
delete[] cchInstallDir;
}
delete[] cchWindowsFolder;
}
delete[] cchIviDir
}
return ERROR_SUCCESS;
}
---
The .wxs source snippet is:
<CustomAction Id="CAKE_WRITE_TSB_INI" BinaryKey="CAKE_ACTIONS"
DllEntry="WriteTSBIni" Return="check" />
<InstallExecuteSequence>
<Custom Action="CAKE_WRITE_TSB_INI" After='CreateShortcuts'>NOT
Installed</Custom>
</InstallExecuteSequence>
---
I ran with the /la switch and got the same sequence on both machines, until
after the CAKE_WRITE_TSB_INI action. I checked the sequencing with Orca,
CAKE_WRITE_TSB_INI is in the InstallExecuteSequence table at #4501, right
after CreateShortcuts as expected. The fopen_s error that I get under Win2K
indicates the folder doesn't exist (2). I used message boxes to pause the
custom action and checked, and despite being past that point in the log file
and sequence, the directory indeed was non-existent.
I have no idea what to try next or why this is behaving differently. Help?
