Visual C++ .NET help

Recommended Posts

Hi,Has anyone compiled a running gauge with Visual C++ .NET and then had it not work on other computers that don't have Visual C++ .NET? I have experienced this many times and have had to resort to having someone else compile for me. Does anyone know what causes this and/or a way around it?-Jon

A way around the problem?Use Borland BCC55 or MinGW to compile the gauge(s)...

Jon,I compile my gauge with VC++ .NET all the time and had no problems at all. No special settings needed.Did you add a yourgauge.def file in your project? That's absolutely necessary to make the gauge work in FS. I'm in office so I can't tell you how it has to look (I just copy and modify the one from the last project ;-) ) but I can post one later today.@Bill:Would you really use a command line compiler when you have on with IDE and integrated debugger? I don't think so. BC55 and MinGW can't even be compared to VC.NET.

Hey guys,As a side note, me and the IDE do not get along very well. I used it for about a year, but after switching to the Visual C linecompiler through the use of makefile and VCVARS32.bat, I am not going back. I do all my coding in TextPad (thanks Matt), then go to a command window and type 1, copying the idea Matt used. 1.bat is a file that simply calls VCVARS32.bat, so I don't have to type that.Sure, press F7 in the IDE, also a one key deal, but for me, the line compiler uses way less resources, and TextPad even highlights the code just like the IDE by recognizing file extensions .c or .cpp or .h, so overall I believe it boils down to preference, not speed.

@Jon: Here's the .def file:LIBRARY YOURGAUGE.GAUEXPORTS Linkage ImportTable@Fabio: I never had any problems with the IDE. I really can't understand what could be the problem. There's no way to do gauges more comfortable and efficient.

Hey Hans,Never had any problems either, just find TextPad more comfortable.

That is one among many things I'm working on. No one is born with all this knowledge; it requires a lot of study and practice...One thing I learned early on though is that no "tool" is better than the hands of the artist who wields it. If the artist has no 'native talent,' that will be reflected in their finished product... :)

Hi,I have always seen that .def file in the project folder and still haven't had any luck. Do I need to add it somewhere in the solution explorer? -Jon

I'm not familiar with .NET, but the .def file is normally for other applications/dlls to load functions out of the compiled dll/gau. It is needed for compiling other modules. Since FS gauges re usually only loaded by FS itself with a standard interface (_ImportTable,_Linkage), you normally don't need to bother about the .def file. Apart from that, with the use of "dllimport" in the gauges.h the .defs aren't needed at all (a t least for VC6.0,GCC, don't know about BCC).Arne Bartels

BCC requires a file like this which reads (well in my setup):EXPORTS Linkage=_Linkage ImportTable=_ImportTableHowever, with VC, it shouldn't be necessary from what I've been told, since the gauge.h defines the exported entries properly, and the linker uses this alright.As for the editor, the IDE etc..., to each is own! I know great projects done without the VC IDE... :-)I personaly have enjoyed the LCC Win32 IDE, and the BCC command line compiler with makefile. Sure the VC IDE is nice, manages the classes efficiently, but I disagree (and the answers from others seems to as well), that in order to work seriously with gauge development you can't do other than VC IDE...As for debuging? the best I know (free) is:http://home.t-online.de/home/Ollydbg/Hope this helps!

I have been using VS .NET myself for a while making C gauges. With the recent release of the panel sdk I wanted to try to get AI traffic data through ITrafficInfo interface. But I don't know how to make gauges using C++. It would be great if someone could post (or e-mail me at arnthelge@mostrealisticai.com) the complete source code of a simple VS .NET C++ gauge project.Many thanks in advance!Regards,Arnt Helge Haaland

Don't know about .NET, but for C++ instead of C compilation with C/C++ compilers you only need to rename the source to .cpp. In principle the new gauges.h should be able to compile with C++, but I haven't checked yet.Arne Bartels
