Windows Explorer Preview Add text file type

Create a .reg file

paste this in to it:

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.properties]
@="properties_auto_file"
"Content Type"="text/plain"
"PerceivedType"="text"

change 'properties' online 3 and 4 to your file extension
(noting the use of '.')

save then double click the .reg file to add it to your registry.

you can now preview the file type in windows explorer's file preview panel.

(no need to restart / relog in or restart windows explorer.)

C++ none white-space character counter.

paramer 1 path of your text file.
if no paramter is passed it will default to a path.

Windows 7 Missing Broadcom bluetooth drivers. hardware ID BTHENUM\{0000110e-0000-1000-8000-00805f9b34fb}

After installing all the latest laptop bluetooth drivers provided by my Laptop manufacturer there remained a  unknown devices missing drivers in the Device Manager and no indication what other drivers were needed, windows software update couldn't diagnose, and any findings on google for the hardware ID suggested old drivers already installed. Installing this update from Broadcom resolved them all.

Add extention to windows explorer preview panel.

These steps allow windows to identify and display a file type in the Windows Explorer preview panel.

1. Start->Run->type regedit and press enter.
2. Open HKEY_CLASSES_ROOT\
3. Find the folder extension name ie .xml
4. If it doesn't exist then make it.
5. Create two keys by right mouse clicking in the folder, select new string value.
6. Name: Content Type
7. Value: text/plain
8. Name: PercievedType (one word no spaces).
9. Value: text

Bug in AAA code base.

A typical daily bug to ponder from AAA code base "Redefining the next-generation of technology in games".


The cut down example implements Vector3 - inheriting 4 elements from base, sets 3 elements and asserts calling base::Validation() because the 4th element is never set.

Note.
1. Clearly no use of debug build during development.
2. Unnecessary code in core code.

const unsigned int NAN = 0x7FC00000;

bool ValidateElement( unsigned int value )
{
    return value == NAN ? false : true;
}

class VectorBase
{
private:
    float m_x;
    float m_y;
    float m_z;
    float m_w;
public:  
    VectorBase()
    {
        *((unsigned int *) &m_x) = NAN ;
        *((unsigned int *) &m_y) = NAN ;
        *((unsigned int *) &m_z) = NAN ;
        *((unsigned int *) &m_w) = NAN ;
    }   
    float GetX() { return m_x; }
    float GetY() { return m_y; }
    float GetZ() { return m_z; }
    float GetW() { return m_w; }

    bool Validate()
    {
        return  ValidateElement( GetX() ) &&
                ValidateElement( GetY() ) &&
                ValidateElement( GetZ() ) &&
                ValidateElement( GetW() );
    }
}

class Vector3 : public VectorBase
{
public:
    Vector3() {}
  
    void Set( float x, float y, float z)
    {
        m_x = x;
        m_y = x;
        m_z = x;
    }

    float GetX() { return m_x; }
    float GetY() { return m_y; }
    float GetZ() { return m_z; }
    float GetW() { return 0.f; }
}

int main(int argCount, char*argStr[])
{
    Vector3 v3;

    v3.Set (0.f, 0.f, 0.f);
  
    ASSERT( v3.Validate () );
  
    return 0;
}
