• alexia_net Elevating a User application to write to a named pipe created by a service running in LocalSystem

  I have a named pipe that is used between a service running as LocalSystem and a client running in the User group. If the service passes a NULL to CreateNamedPipe the EVERYONE group only gets GENERIC_READ, hence the CreateFile for the pipe in the User application returns an access denied error when it requests GENERIC_READ | GENERIC_WRITE. How do I give the user application write capabilites My thinking is to build a SECURITY_ATTRIBUTES with EVERYONE set for GENERIC_READ/WRITE and pass it to CreateNamedPipe. Is this correct -- The personal opinion of Gary G.

• J. Clark size_t: redefinition; different basic types

  Hi, I'm trying to recompile an application that runs on 32-bit Windows to 64-bit Windows. The system is a Xeon processor running Windows 2003 Server and Visual Studio 2005 Professional Edition (that comes with MSDN library). For the visual studio solution, I selected x64 as my platform. However, when I compiled the code, I got the following error message, C:\Program Files\Microsoft Platform SDK\Include\crt\stdio.h(68) : error C2371: ' size_t' : redefinition; different basic types test.c : see declaration of 'size_t' I gather from other posts that I might have mix 32-bits tools.

• Colin Bowern LNK1104: cannot open file 'gdi32lib'

  Using "Build" menu on Visual c++ Express Edition of my first sample source I encountered the following error: LINK : fatal error LNK1104: cannot open file 'gd132.lib' How do I fix it Thanks, Ed. Hello, gdi32.lib is a library from the Windows SDK. As far as I know the Visual C++ Express Edition doesn't include the Windows SDK. You will have to download it and install it separately.

• Wayne.C In Desperate need - Source code from 'obj'???

  Hello guys, I had "quite" a big misfortune recently. My backup extern harddisk stopped working right after I reinstalled my laptop. So I lost all data. Disk is severaly damaged and it would cost a lot to get data. However I'm trying to get data from deleted+formatted laptop. I've searched through almost all files I can get back, but only files regarding my GAME PROJECT(in VS C++) are some "obj" files, VS project, ... some bits here and there, but no source code. I do have some backup of my project but that is 2 months old and I've done quite a lot since then. I know I will have to rewrite the code, but isn't there any way to get source code from "obj" files, so I could get at least some code back Or t ...Show All

• _CN_ Error in loading DLL with ActiveX object

  Hello, I have an ActiveX object, created with ATL, which generates a "Error in loading DLL" message when I try to call one of its method in jscript. E.g. var XSIDial = new ActiveXObject("XSIDial.XSIDialog"); TestCombo = new Array("one", "two", "three"); UseAnim = XSIDial.Combo( "Test for Combo", TestCombo ); I tried in vbscript and it gives the same error.

Bjarne Stroustrup designed C++; you should look at his FAQs. He has a few relevant answers. Oooops, I meant to post that someplace else, but it is still relevant here too. Win32 is Windows. The 32 indicates 32-bit Windows, to differentiate from 16-bit Windows. Of course, 16-bit Windows is no longer used by most everyone. Now that there is a 64-bit Windows, Win32 is misleading, since the term is often used in contexts t ...Show All

• Allan-Nielsen Hashtable in C++

  Hi, I need to use a hashtable in C++. Apparently there isn't one, so I tried to use the hashtable in the System.Collections.

• Pi314159 Problem with VSc++2005. Cannot create project

  I installed visual studio 2005 (standard edition) a few months ago and was very upset to find then I could not succussfully create any c++ project. (I can though create C#, VB etc projects). I thought the install process must have gone wrong so I tried uninstalling/repairing/reinstalling system restore everything etc etc etc etc etc. Lucky I have a second computer, I installed VS2005 and could create c++ projects on that computer perfectly. I think the reason that VS2005 dosent work properly on my first pc is because I used to have the Express version installed on that pc. I uninstalled the express edition months before i installed the standard edition, but after an uninstall some components seam to be left behind. And I think it ...Show All

• Kardi Function not returning for long time....

  In my VC++ application I am using some third party library. When I am calling a function from that library some time (not always) it is taking long time to return e.g. 3 to 5 hours and my application is blocking at that point. If I want to wait only for 15 minutes for that function to return otherwise proceed further. How can I archive this Thanks, Amol Since it is an third party library it's hard to predict the behavior. if it is a commercial product, they definitely had some quality and performance test. Make sure that it's not your system's fault or some other libraries and application's blocking that library or you in calling that function. You can use some profilers to know where you got the catch, and how ...Show All

• Ranier Porting DLL from VS6 to VS.2005 no longr loads (Manifest problem?)

  I'm relatively new to VS.2005. We've been developing and deploying our DLL using VS6 and the DDK (depending on the partner) since I can remember. I installed VS.2005 Pro (Version 8.0.50727.42), tried upgrading my projects (one is the DLL itself, the other is a stand-alone test harness that loads it and tests it by passing it various parameters). So, of course, I'm not positive the projects have all the settings correct. With that caveat, though, I'll explain what I've tried. The test app calls LoadLibrary() with the full path to the dll, and the call fails with error code 14001. After some searches online, several people appeared able to solve this problem by somehow correcting or eliminating their manifests. That led to me to learn ...Show All

• Richard_Wolf Object code format

  Can anyone tell me what is the format of the object code generated by the old 16 bit compilers such as the VC++ 1.52 I believe the 32 bit versions generate the object files according to the COFF format. Is there any way of generating an OMF file using either the object code generated by the VC++ 1.52 compiler or the EXE generated by the linker he he, I totally agree but then I have to work onthis legacy system. Any form of help will be appreciated, thank you. Forum visitors tend to be pretty harsh about VC6 questions on this forum. VC1.52 trumps that by, oh, a bonfire and a 6-pack 10 years ago... ...Show All
