• Windows Networking Development How to lock out a user after a set number of login attempts?

  reply plz.thx in advance. The PAM (Pluggable Authentication Module) module pam_tally keeps track of unsuccessful login attempts then disables user accounts when a preset limit is reached. This is often referred to as account lockout. To lock out a user after 4 attempts, two entries need to be added in the /etc/pam.d/system-auth file: auth required /lib/security/$ISA/pam_tally.so onerr=fail no_magic_root account required /lib/security/$ISA/pam_tally.so deny=3 no_magic_root reset The options used above are described below: onerr=fail If something strange happens, such as unable to open the file, this determines how the module should react. no_magic_root This is used to indicate that if the module ...Show All

• Visual C++ Function name conflict with ENUM name

  Suppose I have a ENUM T_MuxPos_type, where T_MuxPos_type{fixed;flexible;}. While I am coding, I have T_MuxPos_type Mux_pos. When Mux_pos = fixed, I have no problem with gcc but a compilation error with mvs2005: c:\mvs2005\bs_module\source\config.cpp(1925) : error C2872: 'fixed' : ambiguous symbol could be 'c:\panliu_bs\mvs2005\bs_module\source\declareenum.hpp(43) : T_MuxPos_type_E fixed' or 'c:\program files\microsoft visual studio 8\vc\include\ios(183) : std::ios_base &std::fixed(std::ios_base &)' If I solved this problem by Mux_pos = T_MuxPos_type::fixed, gcc compiler will complain about it. So what is the classic method to get rid of this ambigurity I seems to me I should use namespace to solve it, but I don't n ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. OpenGL's modelView to DirectX World matrix

  Hello. I'm writing a rendering library for this application that originally uses OpenGL. I am to write an alternative DirectX renderer. So my problem is, what do I have to do to the OpenGL modelView matrix to be able to use it as the World matrix in DirectX This is the projection matrix setup used in OpenGL: gluPerspective(45.0f, (GLfloat)width/(GLfloat)height, 0.1f, 100.0f); This is my DirectX Projection matrix setup: D3DXMatrixPerspectiveFovLH(&proj, D3DX_PI * 0.25f, width / height, 0.1f, 100.0f); I set my View matrix to identity. I'm using the same vertex coordinates as in OpenGL, and need to (obviously) get them to transform to the same coordinates on screen. So I need to do *something* to the modelView matrix and pop it i ...Show All

• Windows Forms ToolTip IsBalloon

  I am having a problem with the ToolTip in .NET 2.0. When I set the IsBalloon to true, on some computers, the tooltip will not display at all. I thought maybe that is just displaying off screen, but I have also tried to hard code the coordinates. On my computer its fine, on my testers computer it is fine, but on the users computer it doesn't display. If I set the IsBalloon to false, it will show up, but it's the ugly version, that is all square and doesn't have the pointer to the control that I want it. FYI - I have created a Setup project and that is what was installed on the users PC's. So they should have everything that the program uses.

• Visual Studio 2008 (Pre-release) ListView, I would like somthing like SelectionMode.None ?

  I know it’s a little odd. But is there a way to make the ListView “readonly”. I was thinking something in the line of: ListView1.SelectionMode = SelectionMode.None; I know I could just ignore the SelectionChanged event. But the problem is that the styling shows that an item is selected. Best regards,   Thomas S. Andersen   BTW, as a workaround I'm using this at the moment: ListView1.SelectionChanged += delegate ( object sender, SelectionChangedEventArgs e) {     (sender as List View ).SelectedItem = null ; };   Drew: I can’t change the style, because our application will support (runtime loaded) customer styling. But thanks for the xaml paste, it ...Show All
