• Mike Hildner LNK1104: cannot open file cyclic dependency

  I wonder if there is an easy solution to this problem. I have two dlls, which link to each other. For example, a.dll and b.dll In the additional dependencies linker option for a.dll I have b.lib and for the additional dependencies linker option for dll 'b' I have 'a.lib' I only need to create the lib file so that when building the other dll, it will succeed. Right now, if I clearn the solution and try to compile dll a the linker fails of course but does not create the a.lib file that I would need to compile dll b. Only current solution is to manually remove a.lib from dll a linker option and link it with errors to create the lib file and then put back b.lib and link it again to create the dll file. Any ideas ...Show All

• thechristopher How to use a .NET User Control in MFC

  Hi We would like to use NASA World Wind (WW) embedded on a dialog or in a view in an MFC application. For this purpose we have wrapped WW as a User Control and registered it for COM Interop - we have also added the necessary information in order to have it appearing as an ActiveX controls. Not surprisingly we have encountered a number of problems Basically we would like to know if this at all is doable - i.e. can a user control be wrapped as an ActiveX control and then used from within an MFC application Thanks in advance. Lars You could use the new MFC-WinForms interop classes available in VC++ 2005 See http://www.codeproject.com/managedcpp/mfcdialogwinforms.asp and http://www.c ...Show All

• Alexey Rokhin Static lib to DLL?

  Is it possible to convert a third party static library (libusb.lib) to a dll easily, without the source code I want to make calls from C# to C functions contained in a static library. One way is to write a C++ .NET wrapper around the C functions, link the static library at compile time and then call the C++ class methods from C#. Alternatively, if the C functions were in a DLL, I could use the [DLLImport] atribute and Interop services to call them directly from C#. Is it possible to easily convert the static lib to a DLL, if so how I do not have the source code for the library. Thanks, David. Here is a command line script that will convert a static library in one dynamic library! ...Show All

• Mannequin666 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

• Amzi! Why doesn't PDH work?

  Hello, I've been trying to develop an application that reads the CPU load from the computer and the free RAM memory available. To do so, I was primarily thinking about using the PDH interface, since we are building to Windows Server 2003 and Windows XP, both of which already come with the PDH.dll. I downloaded the platform SDK from Microsoft's site, and I am using Visual Studio 2005. My dilemma is, every time I try to compile the source code, it gives me several errors, even with example codes taken from Microsoft's site. It gives me several unindentified objects in _main (it cannot understand/localize the commands, datatypes and so on). I don't understand why. I tried copying the pdh.h and pdh.lib to the main i ...Show All

• Jewelfire1 Settings Designer for C++ Windows Forms apps?

  I'm trying to create a Windows Forms app using C++ in VS2005. I have found many tutorials that specify how to get to the Settings Designer - right click on the project in Solution Explorer, select Properties, and click on the Settings tab. This works for C# projects, but on C++ projects, the Properties dialog is completely different, and doesn't have a Settings tab. So how do I get to the Settings Designer for a C++ Windows Forms project Any help appreciated - thanks. 1>MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup Seems linker are looking for WinMain but failed, what's the entry point of your program (ma ...Show All

• Jens K. Suessmeyer - MSFT Manifest not generated for dlls...

  Hi All, I am trying to build a dll that has some symbols that will be resolved at runtime. The linker is giving me errors (Thats expected!). To forcefully make the linker generate the dll I have used the linker option /FORCE:UNRESOLVED, but I observe that when I use this option I do not get the Manifest embedded in to the dll. In the two other dlls where I do not use /FORCE:UNRESOLVED I get the manifest embedded. Lack of manifest in the said dll makes it un-usable unless I supply the VC runtimes in the current direcotry, which ofcourse is not a good way of doing this. All the neccesary options in the IDE are set for generating the manifest. Is it that when I use this option /FORCE:UNRESOLVED Manifest will never be embedded in to the ...Show All
