I'm writing an Outlook Addin using VC/ATL. This particular addin takes selected email messages and writes them to disk. It also writes all of the associated attachments to disk. We then read everything in to our application outside of Outlook. Using the Outlook object model, this is pretty straightforward as both _MailItem and Attachmen...
We have created an IE toolbar. we are displaying an icon on toolbar by using a static control and keeping image over it. as this static control is not transparent so this icon is displaying some backgroud color(this is default color of windows common controls). is it possible to make the static control as transparent irrespective of br...
This is somewhat related to another question that I've asked that I've pretty much figured out. The last piece of the puzzle is using CoCreateInstance() instead of GetActiveObject(). I don't want to use an existing instance of EnvDTE, so I call CoCreateInstance, which properly fires off a new instance of VisualStudio. CoCreateInstance() ...

I am some ATL code that uses smart COM pointers to iterate through MS Outlook contacts, and on some PC's I am getting a COM error 0x80004003 ('Invalid Pointer') for each contact. The same code works fine on other PCs. The code looks like this: _ApplicationPtr ptr; ptr.CreateInstance(CLSID_Application); _NameSpacePtr ns = ptr->GetName...
Question: I have a COM server with a method as IDL: [id(2), helpstring("method ExtractAvailableScanners")] HRESULT ExtractAvailableScanners( [in] VARIANT scanFilter, [out] VARIANT* scanPresent, [out,retval] LONG* retVal); In the header file this becomes: STDMETHOD(ExtractAvailableScanners) (VAR...
Consider this code: try { ISomeObject pObj(__uuidof(SomeClass)); ISomeObject pObj2(__uuidof(SomeOtherClass)); } catch ( _com_error& e ) { // Log what failed } I.e. I have a block of code which instanciates my objects. Sometimes (a bad install) it failes because some class wasn't properly registered. (I don't have a partic...

I am trying to create a COM component using ATL, and I'd like to raise events for my VB client. I've found numerous tutorials, all of which seem to vary in details, and none of them appear to generate a working solution. Here is what I am doing: (Using Visual Studio 2008): Create a new ATL DLL Project. I've called it ATLEventTest. C...

So I want to use SetThreadLocale to set a threads codepage to UTF8. Up to now, I've been using the second parameter of atl string conversion macros like "CT2A(szBUF, CP_UTF8)" to do this. But I want to be able to set the thread codepage once in the beginning with SetThreadLocale() and never have to use the second parameter of the conver...
I have defined the following CComPtr object and method in my class: private: CComPtr<IRawPdu>& getRawPdu(); // Returns the RawPdu interface pointer from the mRawPdu data member. // mRawPdu is initialized, if necessary. CComPtr<IRawPdu> mRawPdu; // Initialized to 0 in the ctor. Uses lazy evaluation via getRawPdu()....
I'm trying to return a detailed error to VB6 using CComCoClass::Error, but it seems I can only return an error code /or/ a message - but not both. return Error(_T("Not connected"), __uuidof(IMyInterface), HRESULT_FROM_WIN32(ERROR_CONNECTION_INVALID)); results in a generic "Method 'Request' of object 'IMyInterface' failed" error messag...

Wanting to highlight stuff in web pages as you mouse over, but there seem to be so many ways you can set display properties I'm having trouble finding a good way to change the display so that it can change back and still keep close to what the user was already looking at. The IE 8 developer tools Outline tool does something like what I ...
I got a strange compilation error when I followed the MSDN document to use CA2W to convert big5 strings to unicode strings in Visual Studio 2005.

I am hosting a web browser control, and want to provide my own context menu. Ideally, I want to present my own context menu, that contains the original browser's context menu (with all addins etc.) as a sub menu. If that's not possible / to tricky, I'd be ok with e.g. normally showing my context menu, and showing the original one when ...
I am hosting a web browser control, and I don't know how to fetch hotkeys such as [F1] when the control has focus. My primary need is displaying custom help when the user presses F1, however, generally being able to provide additionla shortcuts would be nice. (additional information is available at my related question - I hope it was t...
