Not really an issue, but rather a clarification need.

In the sample, you open an Environment handle, and then a Connection handle and finally Statement handles. Can the Environment handle manage multiple Connections, or do I have to open an Environment for each Connection needed

I have downloaded the project scribble in https://github.com/Microsoft/VCSamples/tree/master/VC2015Samples/scribble.
The compilation is successful but it cannot be embedded in applications like Word or Excel 2016. As materials about OLE is relatively little nowadays. Would you please help fix that? I'd like to develop a program for embedding my simulation result. Thank you very much.

The readme docs are currently in the form of Word flavored HTML, these should be migrated to markdown to display properly on github. Sadly they don't seem to be compatible with an online converter (hence no pull request).

In Unicode builds of CSummInfo::IncrRevNum() the update TCHAR (which is wchar_t for Unicde) buffer gets written as type VT_LPSTR, which always expects a char*

BOOL CSummInfo::IncrRevNum() { ULONG count; _stscanf_s((LPCTSTR)GetRevNum(), _T("%lu"), &count); count++; TCHAR buff[20]; _stprintf_s(buff, 20, _T("%lu"), count); return m_pSection->Set(PIDSI_REVNUMBER, (void*)buff, VT_LPSTR); }

this can be fixed be replacing the last line of the function by

`return m_pSection->Set(PID_REVNUMBER, (void*)tcstocs(buff), VT_LPSTR);`

NB: tcstocs is defined at the top of the summinfo.cpp

Attached is an fresh project file and the only modification from the original is that I want it to load the information always from the odbc.dsn file. Unless I am not referencing an DLL file but yet it still compiles and does not add it to the Import Address Table cuasing this issue.

Also in Release/x86 you can find an precompiled exe that you can see reproduces this issue.

Edit: It seems that somehow /DLL was set in the exe file cuasing this, and that it wont automatically load the DSN file I wanted to load.

Use | operator instead of &

Hi,

I downloaded the ATLCollections sample and tried to compile it using Visual Studio 2019 Preview 3.1. It works fine when selecting default settings in "Project Settings - General - C++ Language Standard" setting.
When selecting "Preview - Features from the Latest C++ Working Draft (/std:c++latest)" as the C++ Language Standard, I get the following compiler errors:

1>------ Build started: Project: ATLCollections, Configuration: Debug Win32 ------
1>StdAfx.cpp

Any idea what the issue might be?

In Visual Studio 2019 I get the following compiler error:

error C2440: '=': cannot convert from 'const wchar_t [1]' to 'WCHAR *'

at Line 141:

You could add a paragraph about how to actually get to a minimal repro source file.

I've personally used https://github.com/CyberShadow/DustMite with --split "*.{c,cpp,cxx,h,hpp}:d" successfully for clang and msvc bug reports.
And my VS plugin to quickly get preprocessed source code.

README.md contains the line "Sample for CPP WinRT here" where "here" links to a 404 error page... Is this a bug or an ironic statement about the state of C++/WinRT documentation across the web in general?
