Hi Nathan, Thanks for the feedback. I have been trying to get the LXBrowser to compile and run under VS2003, Microsoft Visual C++ .NET 69462-006-1580885-18385, and progress is quite slow. I will make some notes as I go along which may (or may not) be of benefit to other developers out there. Before starting, in addition to the compiler details noted above, I am running on XP SP2, latest windows updates, 4GB ram, plenty of other resources. My own background is that I am the owner of a small software house, and have been working as a full time professional developer for the last 25 years, 15 of which are in C++. These notes are comments relating to my experience only, glitches, crashes, etc.. are quite liable to be specific to my own environment, and notes are intended to assist other potential LandXML SDK users in the spirit of open source development. The test file that I am using for development is Tutorial2.XML. To kick off 1) On my PC, none of the pre-built examples executed properly, even after copying the relevant Xerces and SDK DLL files into the LXBrowser folder. The LXBrowser71.exe ran, but crashed out with a fault after loading an XML file and attempting to expand the root node. 2) Attempting to recompile the SDK and LXBrowser, using LandXmlSdkDll1.1.7.1.sln, failed, as the file ReducedObservationCollectionImpl.cpp had not been added to the project. Adding this file allowed the SDK and LXBrowser71 to compile. Checking through the project properties, I notice that LXBrowser71 is including Xerces 2.6, whereas the SDK was including Xerces 2.7. I changed this and rebuild everything. 3) LXBrowser71 (Debug) still failed to run. On further examination, I note that the SDK project is writing libs to the build\bin71 folder, whereas LXBrowser is reading the corresponding libs from the build\bin folder. This needs to be changed to allow a full solution rebuild. 4) LXBrowser71 (Debug), still failed to execute. Visual studio reports LDR: LdrpWalkImportDescriptor() failed to probe c:\LandXML\LandXMLSDK1.1-04062007\Sdk\build\bin\xerces-c_2_7_LXD.dll for its manifest, ntstatus 0xc0150002 Deleting the debug version of this DLL and renaming the release version to the debug name gets around this problem, to the extent I now have a version of LXBrowser that runs in debug mode in VS2003. 5) The CLXBrowserDoc::OnOpenDocument function should provide a good enough example to figure out how to read and dissect a LandXML file. 6) The CLXBrowserApp::OnFileGeneratefile function provides a corresponding example of how to generate a LandXML file. That's all for now, once I have got my head around the operation of these two functions I will post my findings, Regards, Shane -----Original Message----- From: landxml-bounce@xxxxxxxxxxxxx [mailto:landxml-bounce@xxxxxxxxxxxxx]On Behalf Of Nathan Crews Sent: 10 September 2007 14:26 To: shane@xxxxxxxxxxxxxxxxx; Geron, Harrell - Temple, TX Cc: landxml@xxxxxxxxxxxxx Subject: [LandXML] Re: LandXML SDK documentation and tutorials The LandXML SDK was put together and maintained by C++ programmers, obviously better at writing code than documentation. The SDK is built on the Xerces XML parser and the C++ standard template library. The 1.0 and 1.1 versions are both used in commercial software, so they are fairly well tested. The lxbrowser project is a simple example of how the load and use the element/attribute collections and how to produce a LandXML document. Between this and intellisense, the sdk should be very easy to use for seasoned C++ programmers - the intended audience. Any other code examples or document contributions are always welcome.

I'm already in a C++ document/view architecture, so I guess I'm at an advantage here. I have been using the Stingray XML serialization tools here, but being based on the MS XML DOM, the performance on large complex datasets is unusable, so this is not a solution. The underlying XERCES XML SDK used in the LandXML SDK appears to offer good performance and is well documented. That said, I'm very surprised that a project the size of the LandXML SDK doesn't have any of its own developer friendly documentation. It makes you wonder who the indented audience for this SDK is. I've spoken to two other developers at land survey conferences who have implemented LandXML, and neither have used this SDK. To get the SDK to work with Access, I'd probably build a project based on the LXBrowser example, get rid of the view class, and use a CDAORecordSet derived class to copy to an from Access. A total hack, but pretty easy to implement. If I get my head around the SDK, I'll try to put an example together. What language and dev environment are you using?

I wanted to use Access, and have already dveloped a module that reads XML and builds linked tables. Access is supposed to be able to then save an XML file, but I've had problems making it work. If you have some luck with the SDK, I would like to know more about how to make it work.

Is there any documentation or tutorial information associated with this SDK, or is the intended usage to learn the SDK through investigating the browser samples? Alternatively, can anyone recommend an approach to implementing LandXML? We are currently working in Visual C++ 7.1, so the SDK seems like a good approach. Thanks and best regards, Shane MacLaughlin
