• Horst Klein [export]ing helpstrings

  Hi, I want to insert the helpstring into [export]ed idl items in attributed C++ code. I have (i.e. this works): in my.h file [export] typedef enum KillConstant { KillConstantReboot = 1, KillConstantExitOnly = 2, KillConstantShutdown = 3, KillConstantPowerOff = 4 } KillConstant; This generates the following idl: typedef enum KillConstant { KillConstantReboot = 1, KillConstantExitOnly = 2, KillConstantShutdown = 3, KillConstantPowerOff = 4, } KillConstant; I want something like this (doesn't work): [export] typedef [helpstring("Selector for kill method.")] enum KillConstant { [helpstring("Reboot the computer.")] KillConstantReboot = 1, KillConstantExitOnly = 2, KillConstantShutdown = 3, Ki ...Show All

• hawash Visual Studio features - gone in later versions

  I'm trying to figure how to do certain things in a later version of Studio that I could do in VS6 but don't work anymore. Such as (a) dismiss the compilation output window just by hitting ESC, and (b) identifying the exact path to a given source file. I switched from 6 to .NET a couple of years ago, and have regretted not knowing how to make .NET behave like 6 in these particular areas. Now that I'm in the right forum (I hope) - a bit more detail: 1. In VS6, after I had compiled, I could hit ESC and the compile window would vanish. In VS.NET, I have to go click on the close button. Not the end of the world, but annoying nonetheless. 2. In VS6, if I wanted to know the complete path to a particular so ...Show All

• GoDaddy call wrappers and function addresses in DLL's

  Hi, I'm having trouble with C code that stores the addresses of functions that come from DLL's. The problem is I don't get the same value if I take the address of a particular function from two different DLL's. I can see that this is ultimately because the value my C code gets is actually an address in a jump table and my program has more than one one jump table. Here's my situation: .exe doesn't do much, just implicitly linked to DLL A which does all the work DLL A explicitly (calls LoadLibrary) on DLL B. Runs a routine in DLL B by calling GetProcAddress() etc, I'll call this initB() DLL B is implicitly linked to DLL A. When initB() is called it stores the address of a function inside DLL B in a list. I'll call that routine fu ...Show All

• Adam2342342341 C2027 Error: Full class declaration required: Bug?

• mbaclawski mangled name

  Is there any API to retrieve the address of a method (private/public) using the mangled name. the method is supposed to be a class member. we can know the mangled name from the .map file in VC++ 6.0 Please also suggest a method of using this in GCC. einaros wrote: Holger Grund wrote: Erh Why would you expect the unmangled name to produce valid input to GetProcAddress If the function is indeed exported it would very likely have the mangled name in the export name table, but certainly not anything I can think of that would be produced by undname on a C++ mangled name.

• Ralphs This code snippet makes no sense...

  I've come across some code syntax I've never seen. It compiled, but I don't know how, or what it even does! I've been reading a book about DirectX, and in one of the examples, this little piece of code was present: D3DXMATRIX *D3DXMatrixIdentity(D3DXMATRIX *pout); "D3DXMATRIX" is a type, of course. And "D3DXMatrixIdentity" is a function, of course. Now I don't see how this works. Okay, to break it down, first we have a type, which is D3DXMATRIX, then we have the indirection-operator (which I assume is a pointer), and then we have a function (perhaps a call) with a new D3DXMATRIX (pointer) as it's only parameter. How the heck does this work It isn't just a regular function-call. It isn't a function-call that' ...Show All

• Luis Esteban Valencia Muñoz Difference between Visual C++ and Visual Basic.net

  hi, What is the Difference between Visual C++ and Visual Basic.net thanks I think you mean Visual C# .net and Visual Basic .net, right If so, you can refer to this KB URL: http://support.microsoft.com/default.aspx/kb/308470 And if you dont have the time to read it, generaly they are the same, both are complied to MSIL. They differ slightly within the code syntax and some classes. I hope this helps It looks like duck thing is a Visual C++ fan! Both languages differ in terms of syntax, target solutions, and architecture. What I can say is VC++ is super powerful and VB.net is super easy. Couple of months ago Dave Oliver started sort of debate over Channel 9 ( http://channel9.msd ...Show All

• RufusLDK c1xx attempting to compile first preprocessor directive.

  Yesterday I didn't notice any problems with my project, but today whenever I change a file, it compiles the changed file, and then attempts to compile the first preprocessor directive I've defined (in my case WIN32). The exact error reads as follows: WIN32 c1xx : fatal error C1083: Cannot open source file: 'WIN32': No such file or directory After I get this error once, I can recompile again, and since the changed file has now been compiled, it goes directly to linking and doesn't spit this error out again. I'm using VS2005 Standard Edition. What can I do to fix this or to get more information on what's happening I'd added an environment variable which had now been removed, thus ...Show All

• Michael_DE Ref class and friends

  I've been using CPPUNIT for unit testing unmanaged classes. In particular, I can write an unit test class to test a private function of a class. However, the unit test class must be defined as "friend" in the under test class. Since, Ref classes (managed ones) does not support friends, as such, how do I test its private functions A #define private public could fix that... hello Managed type cannot have any friend function/classes/interface, this is by-design. I would like to recommend you to find an open discussion group for CppUnit like cppunit forums to obtain more experimental suggestions. thanks rico ...Show All

• Shazen Question about CoUninitialize and access violations

  Should this sequence cause an AV I made the fairly common mistake highlighted in yellow, and fixed it, but I was surprised that it resulted in an AV only if COM had not been initialized on Thread A. I would like to understand why or why not I should expect an AV in this case.
