Ancient piece of code started giving troubles: When MSVC_FIX_VOLATILE is nothing, it appears that optimizing compiler forgets pT and uses just some variation of adjusted this, which makes sense overall because static cast between the two can be resolved at compile time. However, the problem is that the value of this is wrong and there…
A while ago I posted a tool that updates a [freshly built] binary version information resource and increments build numbers for version identification and tracking. This time it is a variant of the tool: the utility would check git details for a given repository clone and embed it as a string item of the version…
I already wrote earlier on 32/64-bit issues with Visual Studio. The problems are not frequent but when they happen they are pretty confusing. Here is another one today. C++ code is simple: #import “libid:59941706-0000-1111-2222-7EE5C88402D2” raw_interfaces_only no_namespace CComPtr<IObject> pObject; ATLENSURE_SUCCEEDED(pObject.CoCreateInstance(__uuidof(Object))); BYTE* pnData; ATLENSURE_SUCCEEDED(pObject->Method((ULONG_PTR) (BYTE*) pnData)); A COM method returns a pointer to data – pretty straightforward,…
Great news for those suffering from Visual Studio 2010 IDE crashes with losing recent source code changes. Visual Studio 2012 is way more stable (event with Visual Studio 2010 Platform Toolset!) and suffers from crashes without losing editor changes. The worst thing you seem to be getting is: Which is an access violation or stack…
An amusing bug which seems to be affecting three of the versions of Visual Studio in a row: 2012, 2010, 2008: a double right angle bracket closing (or just present) the declaration of templated base class is breaking Visual Studio outlining capability (code scout? Intellisense? whatever). Have a space there and you are fine.
A colleague pointed out that code snippet in previous post is misusing ATL’s ATLENSURE_SUCCEEDED macro making it [possibly] evaluate its argument twice in case of failure, that is evaluating into failure HRESULT code. As it is defined like this: #define ATLENSURE_SUCCEEDED(hr) ATLENSURE_THROW(SUCCEEDED(hr), hr) It does things in a straightforward way, for a code line ATLENSURE_SUCCEEDED(pFilterGraph.CoCreateInstance(CLSID_FilterGraph));…
If you dare to convert your C++ ATL Service project created with an earlier version of Visual Studio to version 2010, as I recently did, you might find yourself surprised with why the hell the bloody thing does not work anymore as a regular executable. After passing compiler/linker and SDK update issues, which you possibly…
