VisualStudio2003 and .netmodule sGrabert27-Aug-07 22:11 sGrabert 27-Aug-07 22:11  I'm currently using VisualStudio2003 (and cannot change due to the fact that other team members are using it too). My current project uses managed code to dynamically link a .NET-DLL into my program, works so far. The only problem is, that to compile and link this DLL I need a [dllname].netmodule file, which can only be generated with VisualStudio2005. The file is generated by linking the dll into my project (references) and automatically used when the dll is loaded. VC2003 does not generate this file automatically, but if it is not present, the DLL cannot be used (access violation). Using google I found this to be a bug in VC2003 but no appropriate solution. Is there any way to generate this file with VC2003 (compiler switch, etc.) automatically?? Thx in advance Re: VisualStudio2003 and .netmodule sps-itsec4627-Aug-07 22:44 sps-itsec46 27-Aug-07 22:44  Hi, AFAIK it's currently only supported to compile a netmodule in VS2005 via command line. Currently there is no IDE support for it. Because this really bugged me I looked for another way and ended up changing a single tag in the csproj-file. Before change: <OutputType>Library</OutputType> After change: <OutputType>module</OutputType> Works perfectly for me (VS2005) but you've to check if this works in VS2003, too. After you've done this change take care not to change the output type of this project via the IDE anymore. It will of course overwrite your hand-changed tag. Perhaps the following links can help you, too: http://support.microsoft.com/?scid=kb%3Ben-us%3B309805&x=9&y=11[^] http://support.microsoft.com/kb/311416/EN-US/[^] cheers, mykel OMM: "Let us be thankful we have an occupation to fill.

Re: VisualStudio2003 and .netmodule [modified] sGrabert28-Aug-07 0:07 sGrabert 28-Aug-07 0:07  Well, thank you for your answer but that didn't help.. I'm using VC2003 and a .vcproj file to create the dll. The .NET library is linked inside(!) this dll as I want to use some of the implemented functions. The .NET library is linked via assembly reference only: AssemblyReference RelativePath="$(SolutionDir)\include\[.NET].dll" I can access the namespace and library classes at design time. The weired thing is that VC2005 created the [.NET].netmodule automatically (with the same project), but VC2003 does not. Looks like there is no (easy) solution for this bug and I have to use VC2005 to create the module file.. thx -- modified at 6:16 Tuesday 28th August, 2007 Convert vector to managed array hansipet27-Aug-07 4:36 hansipet 27-Aug-07 4:36  Hello, Is there an easy and fast way to convert an vector to a managed array?

Re: Convert vector to managed array hansipet27-Aug-07 9:01 hansipet 27-Aug-07 9:01  I think everyone knows that code can be written, compiled and execute. But not every code is the best and fastest solution for a given a problem. I think it would be better when you don't give such stupid hints! Re: Convert vector to managed array George L. Jackson27-Aug-07 10:38 George L. Jackson 27-Aug-07 10:38  He is telling you that you need to determine the "best and fastest" solution on your own because each solution has trade-offs that affect certain situations negatively. Since you know your situation and we don't, you will get stupid hints! So, get your compiler and profiler, and have fun!

And also I dont know what is the use of these funcations. For our need we need to create our own copy constructor ..then what is the use of default (in built) copy costructor. Also please breaf what is the use of these inbuilt (default) funcations. Nandu. Re: Default funcations in a class George L. Jackson27-Aug-07 10:30 George L.

Jackson26-Aug-07 15:51 George L. Jackson 26-Aug-07 15:51  This is really not a C++/CLI question. This should not be posted here! Anyway, there is a lot of information on the web and printed media about vector and STL in general: http://www.informit.com/guides/content.aspx?g=cplusplus&seqNum=91[^] "We make a living by what we get, we make a life by what we give." --Winston Churchill declaration and use of a buffer (pile TCP/IP) aefmaaradji26-Aug-07 13:25 aefmaaradji 26-Aug-07 13:25  Hello, I would like to know how to use and declare a buffer in the visual c++/cli because I made a capture TCP/IP (sniffing) but my application was being length (in a networks with very high speed like 100Mbit/s), to regulate this problem a beffer should be used. aef Sending Native Struct via TCP tjkrz26-Aug-07 9:02 tjkrz 26-Aug-07 9:02  I need to communicate with a non-windows platform via TCP. The message will be a unmanaged data structure. How can I encode this into a managed type that the Socket.Send command can handle? The message must be decoded on the other platform, which won't have the .NET framework. Re: Sending Native Struct via TCP Mark Salsbery26-Aug-07 10:09 Mark Salsbery 26-Aug-07 10:09  You'd need to create an array of Bytes (for the Socket::Send()) and "serialize" a managed type into a stream of bytes (representing the structure) in the array. A couple things to keep in mind: Structure packing can be different on different languages/platforms.   This means you have to ensure each of the structure's members is at the appropriate offset in the Byte array. The BitConverter class can help for converting managed base types to a stream of byes, but you need to deal with byte order (endian-ness) of multi-byte types if the other platform is different.  If this is an issue, multi-byte integer types sould be sent using network byte order.  IPAddress::HostToNetworkOrder() and IPAddress::NetworkToHostOrder() can do the conversion but the other end needs to know to convert the sent network-order bytes back to host-order.

Luc Pattyn26-Aug-07 10:51 Luc Pattyn 26-Aug-07 10:51  To calculate a square root manually, these are the first steps: - take a large sheet of paper - write your number in the top left corner - group the digits by two, form right to left - figure out the square root of the leftmost group (which holds one or two digits) - that gives you the first digit of the result - estimate the second digit by checking if the square is still less than the original number (using two groups now) etc. Good luck.

It was offered to all CPians by our colleague Malcolm Stuart, who ends a lot of his contributions by the very good advice: "More functions should disregard input values and just return 12. It would make life easier." And I can confirm life is getting easier this way.

For a definition, I refer to this week's third tip; Google offers about 1000 hits for CPian, most of them refering to inhabitants of CodeProject. Unfortunately Wikipedia and MSDN are not up-to-date on this issue.

Now, I have the smarts to figure out this 1 Billion-lightyear wide void in space that is 10 Billion light years away. Thus, twelve might be a promising number.
