• Windows Forms Datagrid for multiple tables

  I have a dataset of four tables (actually more than that but for simplicity now) and let's say its table names were A,B,C,D. I put a relation between table A and B and another relation between C and D. I made two datagrids in the VS designer. The first datagrid (which has datasource=ds, datasmember=ds.A) is OK for showing plus sign in front of each row of table A and when I opened this plus sign it showed the relation and child rows from table B. It worked as intended.  But when I made another datagrid (datasource=ds, datamember=ds.C), it didn't work in a same manner. This second datagrid showed the plus sign in front of ...Show All

• Visual Studio Team System Difficulties in getting Code coverage information

  I am testing ASP.NET web controls and am facing difficulties in getting code coverage information from my tests.  For testing our web controls, I am using the [HostType("ASP.NET")] and [UrlToTest(" http://localhost/TestSite ")] attributes in my test projects to either test a website that has these webcontrols, or dynamically add these controls to a empty test website and test their properties and methods. So my project structure is like this  c:\>     - InetPub         -wwwroot            -UnitTestWebSite   & ...Show All

• Microsoft ISV Community Center Forums Run-time error '3085' - Undefined Function in expression

  I have an intermittent problem with an Access database. I have a function defined in a module shiftletter, which takes two parameters. This function is used by a query. Nine times out of ten the query called by VBA works. But occasionally I get the above error, to make the query work I have to reboot my machine. Opening and closing the database does not help. Running the same query in the query window works. I have tried moving the function to a new module; compressing the database and using the repair option. None of these have cured the fault. Anyone got any ideas Hello ADG, this might help. ...Show All

• Visual C++ Problem using argv in main

  Hello there, I am pretty new at this C/C++ I am writing a console program, and from what I read here, and around the internet is that the argv array in main()  is supposed to hold any arguments entered on the command line... argv[0] is the name of the program, and argv[1] to argc is the arguments. So if I were to write a program that opened a file in binary mode. To run it I would type executable and then the file I want to open and operate on. example: C:// binaryopen  binaryfile.bin binaryopen is the name of the program, argv[0] binaryfile.bin is the file being operated on, argv[1] at least that's what the internet ...Show All

• Visual Studio Team System Team Build - PublishRun Error

  My first Team Build build, errored out on "Build process and custom task errors".  I get: Error  PublishRun: Only one usage of each socket address (protocol/network address/port) is normally permitted My code does nothing with sockets which leads me to believe this is an internal TeamBuild error. Building just one configuration at a time is a fine workaround for now.  Thanks. ...Show All

• Visual C# How to create local instance of the remote object

  The question is How to create local instance of the remote object For example, the server class MyClass in computer A contains a method create() to create a file in "c:\", if the client in computer B creates a remote object from A :  MyClass mc = new MyClass() and call the method create(): mc.create(), it will create a file in the c:\ of A, not B. How can I create a local instance of MyClass so that when I call the create() method, it will create a file in B Thanks a lot! Hi, I think with remoting you create a local proxy to the remote object and not a local instance ...Show All

• Visual Studio Language Service Options - what's the correct approach?

  What is the recommended approach to adding options to a Language Service DialogPage provides an easy way to add Options pages. Visual Studio then manages the presentation and serialization, but it seems hard to access the values actually in the page each time via the DTE. What is the role of the LanguagePreferences class The documentation suggests extending it, but they you have to manage the serialization, loading, etc. The XML Editor seems to take the approach of extending the LanguagePreferences class to add it's own options, and adding customized DialogPage-derived pages which update it's extended LanguagePreferences i.e. it does ...Show All

• Visual Basic Detecting end of Explorer Copy

  I am just learning VB but am pretty comfortable writing moderately complex code and using the help files. I am trying to detect when an Explorer copy of a file ends to start another process. The copies I am interested in are rather long, due to large file sizes and a slow internet connection. I have been able to detect when a stand alone process ends by using "Process.GetProcessesByName(ProcName)" then checking on exit with ".HasExited" but the copy window evidently is a thread internal to Explorer and Explorer doesn't exit when done. I have looked at Explorer memory usage, and just about all of the parameters a ...Show All
