Thanks Christopher, I had a look bur my function still is not working. Does
anyone know if there is any documentation on the WcaAddTempRecord because
I'm not even sure on the attributes or that. At the minute I have:
hr = WcaAddTempRecord(&hTable, &hColumns, L"ListBox", NULL, 0, 4,
L"COMPORT", 1, buffer, &insertError);

I have an example in C# using DTF at:

fore-install
I know your using C++ so you'll have to look at what the underlying function
is for each class/method in DTF and then see what tricks WiX
provides for creating records and what not. Then of course there's all
the wonderful casting you have to do in C++.
Eitherway, maybe it'll just validate the general flow and help you catch
something thats missing. (like 3 vs 4 fields)

Your call to wcaaddtemprecord looks ok. The only thing I can guess at is
that you need to specify all 4 columns of the ListBox table, rather than
just the
3 you have.
The other difference from my code is that I also have MSIDBERROR insertError
= MSIDBERROR_NOERROR; And I give &insertError as the 4th argument.

Subject: [WiX-users] Populate a list box from a custom action
Hi I have a Custom Action in C++ that gets the Com ports of a machine and I
need to get these into a listbox in my staller. I have the following but it
is the wcaAddTempRecord is not working and I cannot find any good
documentation on this. Thanks
extern "C" UINT __stdcall GetDatascanPort(MSIHANDLE hInstall)
{
AssertSz(FALSE, "debug here");
DebugBreak();
HRESULT hr = S_OK;
UINT er = ERROR_SUCCESS;
HKEY keyHandle;
DWORD i,openStatus,cb_value_buffer,cb_buffer,dwType;
char value_buffer[100],buffer[10];
MSIHANDLE hTable = NULL;
MSIHANDLE hColumns = NULL;
hr = WcaInitialize(hInstall, "GetDatascanPort");
ExitOnFailure(hr, "Failed to initialize");
WcaLog(LOGMSG_STANDARD, "Initialized.");
if (RegCreateKeyEx( HKEY_LOCAL_MACHINE,
"HARDWARE\\DEVICEMAP\\SERIALCOMM",
0,
"",
REG_OPTION_NON_VOLATILE,
KEY_QUERY_VALUE,
default_sa(),
&keyHandle,
&openStatus ) == ERROR_SUCCESS )
{
for (i=0;;i++)
{
cb_value_buffer = sizeof(value_buffer);
cb_buffer = sizeof(buffer);
if (RegEnumValue(keyHandle, i, value_buffer,
&cb_value_buffer,
NULL,
&dwType,
(unsigned char *) buffer,
&cb_buffer) !=
ERROR_SUCCESS)
break;
if (dwType != REG_SZ || strlen(buffer) > 6)
continue;
}
hr = WcaAddTempRecord(&hTable, &hColumns, L"ListBox", NULL, 0, 3,
L"COMPORT", 1, L"Item 1");
RegCloseKey(keyHandle);
if (hTable)
MsiCloseHandle(hTable);
if (hColumns)
MsiCloseHandle(hColumns);
return WcaFinalize(hr);
}
LExit:
er = SUCCEEDED(hr) ? ERROR_SUCCESS : ERROR_INSTALL_FAILURE;
return WcaFinalize(er);
}
My list box is, it has a sample list item:
<Control Type="ListBox" Property="COMPORT" Id="Comport" Width="80"
Height="40" X="80" Y="165">
<ListBox Property="COMPORT">
<ListItem Text="COM 3" Value="0"/>
</ListBox>
Kind Regards,
Natalie Carr
