• Smart Device Development Problem when serializing messages to be sent over the net

  Hi all, I'm developing few .NET client/server applications that all use the same model of communication - it sends and receives messages using Sockets. When I serialize/deserialize the message I'm using the BinaryFormatter class. Now I need to build my app so that it is executable on Pocket PC. My first problem was that Compact framework 2.0 SP1 does not contain BinaryFormatter. I was looking for any other serializer-class feasible in the CF and have found only XmlSerializer. So I'm using this class. My actual problem with the XmlSerializer is that it does not serialize my object automatically - I mean that I have always to add the XmlInclude attribute. My class structure is like this: [XmlInclude(typeof(NetMessageBase))] ...Show All

• Visual Studio Team System Linking to a work item inside team explorer

  I need to create a link that when clicked, will bring up a specific work item inside Team Explorer. I'd like this to happen whether or not Visual Studio is running. I've done a little bit of preliminary work, and it seems feasible with the VSIP linking code. Can anyone provide insight Is this do-able Thanks, Jonathan Cran jcran@iastate.edu Are you talking about having a web url, clicking on which opens VS TE and shows a specific workitem We do not have protocol handler for this yet and is not possible in V1. You can open a query though by giving a path to a ".wiq" file. There is no equivalent for workitem like wiq file in V1. One option is to create a wiq file with a query that says "id = <id-number ...Show All

• Visual C++ HEAP: Free Heap block modified after it was freed

  hello everyone, i came across this problem: HEAP[core.exe]: HEAP: Free Heap block 3af2a8 modified at 3af2d0 after it was freed Windows has triggered a breakpoint in core.exe. This may be due to a corruption of the heap, and indicates a bug in core.exe or any of the DLLs it has loaded. the problematic line is new Log(....); the Log is a class i defined. i maintain a std::vector as a history log to keep a record of every step. also i maintain a bool type variable to enable the user to choose wether or not to keep records. so the code is something like this: class Log { ... } std::vector<Log *> history; bool keepRecord=false; void record(Log *theLog) { if(keepRecord) { history.push_back(theLog) ...Show All

• Visual Studio Team System Filtering work item with a data range and returning the date as part of the datasets fields simultaneously

  Hi, I'm able to filter based on a date range. The problem is that I can't find a way to add the Date dimension to the list of column returned by the dataset. In other words, I want to return a list of work item that is filtered based on a "from date" and "to date" and have the date of each work item records in the returned list.

• Windows Forms Generic Bootstrapper - SQL Express Named Instance

  I'm using the bootstrapper to install a named instance of SQL Express as a prerequisite. If SQL Express is installed on the computer but my instance isn't, the bootstrapper will bypass the installation of my named instance. 1. Is there a way of passing an argument to the SqlExpressChk.exe to look for the named instance instead of any SQL Express installation 2. Is there a better way of accomplishing my installation goal Thanks, Wayne I'm pretty sure he's correct. I have one possible idea...

• SQL Server Groups: keep together -> can't find it

  Hello there. I've got a little problem. I'm deploying reports in RS. I also have to rebuild old CrystalReports-Rreports in RS. 90 % of them are using a "keep together" function. I've read a lot in forums that there must be similar function in RS. I also found descriptions where this property should be, but there isn't. For report-developing I used (RS2000 with VB.NET2003) and (RS2005 with VB.NET2005). Neither of them have this property for table/report. Do I have to install a ServicePack Any other ideas Thanks, Tobi I am having the same problem basically because SSRS does not have a "Keep Together" functionality. I am trying to devise a way to simulate this as it is in Crystal. BJ ...Show All
