You can use XMStoreFloat4x4 to convert XMMATRIX to a XMFLOAT4X4.

You should be able to pass in XMFLOAT4X4 to setTransform by casting.

DirectX::XMMATRIX matProjection;   
DirectX::XMFLOAT4X4 projectionMatrix;
DirectX::XMMatrixPerspectiveFovLH(&matProjection,DirectX::XMConvertToRadians(45),1.0f,100.0f); 
XMStoreFloat4x4(&projectionMatrix, matProjection);
d3ddev->SetTransform(D3DTS_PROJECTION, (D3DXMATRIX*)&projectionMatrix);  /*problem!*/   // set the projection
