Duplicate Toolbars/buttons after reinstalling Visual Studio .Net

My Visual Studio.Net crashes frequently and I then asked my colleague to reinstall it for me. Sadly, after reinstallation, the GUI becomes rather chaotic, with duplicate toolbar buttons as shown below:

 

Using /clr and incompatibility troubleshooting in MFC applications

In some circumstances, to use C# Winform or other .Net objects in MFC applications, the “/clr” directive should be used in the MFC project settings. However, it is found not always possible to use “/clr” to avoid conflicts with other projects in the same solution.

The workaround is to apply “/clr” on a specific cpp file, rather than on the entire project!

 

How to use .Net Winform or UserControl in MFC

For VisualStudio 2005 or above versions, refer to below link

http://msdn.microsoft.com/en-us/library/ahdd1h97.aspx
http://msdn.microsoft.com/en-us/library/b1kyh79x(v=VS.80).aspx

The basic idea of this implementation is to use the class CWinFormsControl<NameSpce::WinformClass/UserControlClass> to host .Net Winform or UserControl.

This article presents how to implement this in VS2002 environment.

 

How to manually setup/modify Visual C++ Project settings such as /GL, /Yu etc. in VisualStudio.Net 2002

Most Visual C++ project settings can be setup using the Project Properties dialog, but not all. In my recent project, I am trying to host Windows Form in MFC (VS2002), and the directive “/clr” must be used.

Once “/clr” is used, some other directives such “/GL” must be disabled to avoid incompatibilities. After searching MSDN, I have found that “/GL” is related to “Whole Program Optimization”, but even after disabling the whole program optimization in Visual Studio 2002, it is stated that the “/GL” switch is still turned on. I have tried every setting, but have no way to disable this, and this is clearly shown in the final command line.

 

MFC:Using Numerical Recipe in C++

I was forced to come back to MFC, as the company I am now serving still uses VisualStudio.net 2002.

The happy days using C# are gone,… tears…

Below is my trial to use code from Numerical Recipe in C++, 3rd ed, in a MFC dialog application:

1. Include “nr3.h” where all the data structures and function interfaces are defined.

2. You need also to include specific module in which you are interested in. In this example, I am trying to use LU decomposition based methods to solve linear equation.

 

Shell extension and ATL development

1. An absolutely must-read paper is here.
2. To install the ATL dll to the target machine: Regsvr32 /s Your.dll
3. To get the shell extension to work in x64 mode, use VS2005 or VS2008 ATL wizard, as VC6 does not support to change the x86 or x64 platforms;
4. In VS2008 wizard, some interface’s signigures are different from that in VC6 enviromment, for instance, in VC6, for the IContextMenu inteface , the function to be implemented is:
   STDMETHODIMP GetCommandString(UINT, UINT, UINT*, LPSTR, UINT);
   and in ATL 9.0, however it is:
   STDMETHODIMP GetCommandString(UINT_PTR, UINT, UINT*, LPSTR, UINT);
5. To generate the DLL for x64 machines, in VS2008, go to Project->Properties (or Alt+F7), then Configuration Properties-> Linker -> Advanced, on the right side, go to “Target Machine”, change this to “MachineX64 (/MACHINE:X64) and Rebuild.
6. The transparency of the icon in the shortcut menu can be found here.
