• Visual C++ very strange problem with std::string, std::stringstream and bad_alloc exception

  Hi, I am developing an application which looks like this: App A uses DLL B which uses DLL C. B And C are non-MFC DLLs. A is an MFC console-app. B exports a class class1. Class1 contains a single member of Class2. Now the following code leads to bad_alloc exceptions in std::string: in A lets have Class1 *pmyclass1 = new Class1; Class1->foo(); void Class1::foo() { m_class2.bar(); } void Class2:bar() { std::string foo; foo = std::string("This string has more than 15 characters and will lead to heap corruption"); } When the last line of bar is executed bad_alloc is raised. How can that be What's wrong here Additionally bad_alloc will also be raised if you dec ...Show All

• Windows Forms Typed DataSet's with Large Amounts of Data

  Is there any documented maximum number of tables, relations, or records in a typed DataSet object in .Net 2.0 I have a large DataSet (the select command returns 24 result sets with tens of thousands of records total (approximately 90K records of varying sizes.)) If I fill from a DataAdapter into an untyped DataSet, the fill operation returns in just over 1 minute (approximately the time of the select procedure.) If I then merge this untyped DataSet into my typed data set (after calling BeginLoadData on each table) with constraints turned off (EnforceConstraints = false) the merge takes approximately 20 minutes. If I then enable constraints, the program runs for slightly over 20 minutes, and returns an Out of Memory exception. I expec ...Show All

• Community Chat Wireless Speaker System

  Hi I like to design many things and im wondering if its possible (and if its already been made) a speaker system where you can keep adding more to your system. Basically you have the transmitters, these will be plugged into anything that plays sound from a PC to a TV or Hi-Fi system. There can be only one channel where all these play to so you can have either one thing playing or more than one thing Then you have the speaker which recieve the audio from all the transmitters, the speakers can be added in any number so you can have a few in each room of the house. Awesome for a party! Im stuck on the power for the speakers becuase the transmitters can be plugged in but haveing ever speaker plugged in to the wall or every speaker ...Show All

• Software Development for Windows Vista How to cancel the branch of a ParallelActivity that does not complete

  Here's my situation. I ParallelActivity with two branches; one branch needs to continually check for a certain database condition. The other branch waits for a period of time, sends an e-mail, waits for another period of time, and then sends a final e-mail. My problem is that when one of these branches finishes I need to cancel the other. I have a working solution but don't like it much. When one branch finishes, I throw an exception and then catch that exception at the ParallelActivity. This, of course, causes the other brances in the parallel activity to cancel, but surely there is a better way. I could write my own Activity that implements IEventActivity and then use a ListenActivity which would cause all other activities to cancel when ...Show All

• Software Development for Windows Vista Fault handling in RC2

  I can't seem to get fault handling to work in RC2. It worked for me in Beta 2.2. I have a state machine workflow that I've published as a web service. I've added a fault handler activity with one code activity as a child. My code activity gets executed, but then, when I retrieve the Fault property of the fault handler activity, it's always null. Any thoughts You need to be using GetActivityByName(string,bool) to get the correct activity. Because of spawned contexts in a StateMachine you are getting the template activity an not the actual instance. For more info on spawned contexts take a look at Nate's blog post . ...Show All
