• Visual C++ Binary compatibility between vs2005 and vs2003 streams?

  I've got a project that's a plugin to a larger program - specifically, it's a plugin to Alias Maya 7.0. For file loading, I implement a function with the signature: MStatus MPxSurfaceShape::readBinary( std::istream& in, unsigned length ) The problem is that the istream isn't working very well. Specifically, I have some code: char *buffer = new char[length]; in.read( buffer, length ); if( in.bad() ) return MS::kFailure; There are a couple of problems that happened. First, the read failed. It reads 0 bytes into buffer. Second, in.bad() returns false, even when the read doesn't happen - in.fail() returns true. If I create a st ...Show All

• Windows Forms .net developed app Compatability

  Hej people. I have developed a small application with visual studio based on .net and with  access 2k db. I have tried it out on my own xp computer as well as w2k3 server and it runs. Does any one know how it would behave on win98/w2k clients  in general Thanks It will crash and corrupt the boot partition in Win98/Win2K. The monitor will begin to melt and the mouse will turn into cotton candy.  The left wheel on your chair will then break followed by your right armrest. Just kidding...  :) It should work without a problem. Good luck! ...Show All

• Software Development for Windows Vista Beta 2 Debugging question for HOL 1

  Hello, I'm working through the Hands on Lab (HOL) #1 for WF Beta 2, Exercise 3 and task 7. Everything's been working according to the lab instructions until I got to the debugging section. I'm seeing a couple of strange things: 1. Step 6 tells me to step into the code for the ReportSubmitted_Invoked handler. I've tried this, but the debugger doesn't go to the code level; it simply highlights the next activity in the workflow designer. I also tried explicitly setting a breakpoint in the ReportSubmitted_Invoked method of the code beside file, but it's not hit and appears disabled. The text 'ReportSubmitted_Invoked' is written to the cons ...Show All

• Visual Studio Team System Upgrade to Team Foundation RTM: Reports

  In http://blogs.msdn.com/team_foundation/archive/2005/11/15/493188.aspx  it states (see below) that reports are going to be broken due to changes in the data warehouse.  Is there any possible way to get advance notice of the details of these changes We've created several custom reports since the release of Beta 3 and we have many more scheduled.  We'd like to be able to categorize these based on risk and likely change costs, but it seems that we're faced with "Things will change, but we're not telling you" for the second time.  Please advise.
