• Windows Forms Bug? Bound listboxes with dataviews - Problems with SelectedIndex and view

  Hello, Perhaps I've just been staring at this code for too long this morning, but I'm running into what I believe to be two distinct problems with two listboxes and how the SelectedIndex property interacts with the items in my list. In addition, once items are moved around between the two listboxes, I have this one "phantom" item in my listbox&nbs ...Show All

• Visual C++ Comparing ref pointers for equality

  Now that operator overloading allows to ref classes to be compared for equality using == syntax, how does one compare the actual ref pointers ( ^ ) for equality instead As an example: SomeRefObject ^ obj1(..initialized somehow); SomeRefObject ^ obj2(..initialized somehow); if (obj1 == obj2) // This compares the objects themselves for equality in C++/CLI I assume. How do I compare the ref pointers themselves ( ^ ) for equality You have to downcast to System::Object first - this avoids any equality operators that may be defined if (static_cast<System::Object^>(obj1) == st ...Show All

• Visual Studio Team System Organizing source code and projects - looking for best/recommende practices

  We have a large website which will comprise up to 30 VS-projects. Some of them are shared assemblies (DAL, domain logic) and some of them will be very feature oriented (business portal, catalogue management, membership etc). Our project model is a customized version of “Agile RUP”. We will continuously have 2-3 development projects running (each with 2-6 months duration) – each project having two or more iterations. These projects will have their own specifications, project plans but share a lot of documents related to the “large website” project. Having looked at MSF Agile, we think we must a separate Team Site for ea ...Show All

• Software Development for Windows Vista using regsvr32 in Vista 5231 to install COM component fails to write to registry

  I am trying to register a com object (dll) with regserv32 in Vista 5231. My Dll is being loaded and my DLLRegisterServer method is invoked which uses RegCreateKeyEx and RegSetValueEx to write to the registry (HKEY_CLASSES_ROOT\CLSID\XXX\XXX). I am writing everything out to a file just to make sure everything is going ok. all the RegCreateKeyEx calls and RegSetValueEx calls are returning success, but when I look in the registry my newly created keys aren't there. Are there any known issues with using RegCreateKeyEx or RegSetValueEx to modify the registry with Vista 5231 I resolved my issue. there seems to b ...Show All

• .NET Development Copy row contents to same table as new record

  Hi all, I've searched a lot but I am looking for a simple way for a user to copy the contents of an existing record to a new record in the same table. I was hoping to find a dataset.table.row.item(index).copy feature, or something similar. Any suggestions are much appreciated. Thanks! Thanks again for your help! I had not tried the Constraint method I mentioned, and I'm glad I waited! In the meantime I had done this; (it really stinks so hold your breath) 'Dim newrecord As DataRow 'newrecord = Me.MachineDataSet.tblFeeder.NewtblFeederRow() 'newrecord.Item("Name") = NameT ...Show All

• .NET Development ArrayList.Add problem - values and references

  Hi, I'm having a problem with my code. I have an Array called moves of length four that contains ArrayLists, each of which I modify according to user input. Each time input is complete I want to save a copy of the moves so that I can go back and retrieve previous entries. In order to do this I have a separate ArrayList called history to which I add moves after input using history.Add(moves); In this fashion I can retrieve previous entired by accessing history(0) for the first set Array etc. Sadly each time I alter the contents of moves , all of the objects I have added to history are also changed, so I just end up with an ...Show All

• Visual Studio ParameterFieldCurrentValueException when exporting or printing crystal report

  Hi. I get the ParameterFieldCurrentValueException exception when I try to export or print a crystal report (I am using the version bundled with Visual Studio 2005). The report works fine until I add a sub report to it. The sub report has 1 table but I have not put any of the fields onto the report. Neither does it have any parameters set up so I can't see why it is looking for parameters. Thanks, Will. Yeh, I have exactly the same problem as soon as you have a sub report on the main report and try to execute it, it throws a missing parameter exception. I created a app in the Beta 2 release of VS 2005 an ...Show All
