• Software Development for Windows Vista Sequential Workflow Cancellation

  This question has appeared before but never with a clear answer. When would a SequentialWorkflowActivity execute its cancellation handler The SDK sample "CancelWorkflow" does indeed "cancel" the workflow by raising an exception, but this isn't a "cancel" in the sense that the cancellation handler runs. I have not been able to find a scenario where the cancellation handler runs, yet it seems emphasized by the designer. What am I missing Scott - a CancelHandler on a SequentialActivity gets fired when it is a child of a parent that is executing multiple children in parallel (ala the ParallelActivity) ...Show All

• Smart Device Development SQL Mobile Debug Speed

  Is there a way to "optimize" the what parts of the code can be debugged, rather than everything What I am after here is to debug my own base code, but get limited information from the debugger when talking to the SQL Mobile database. I have a simple form that builds a tree with about 10 nodes that were generated from a query from the SQL Mobile database. When you run in debug mode, it took 25 sec to bring up the form, but only 1 sec when compiled for release. I do not see that type of speed up on other parts of my code, but debugging with SQL Mobile seems really slow. Thanks, Juan Foegen ...Show All

• Visual C++ '0' character oddity

  I'm working on a Poker game for a class project and I've come across an unexpected behavior of the '0' character. One I know it might be better to use '1' but, I haven't, up to this point anyway. I'm just wonder if anyone could explain to me why this code is actually working. It confounds me. Is it a bug I'm trying to sort a hand of Card objects, implemented as such: struct Hand { const static int COUNT = 5; Cards cards[COUNT]; ... }; I know I need to overload the < operator. Here's class Cards: struct Cards { char suit, value; void setSuit(char suit) { this->suit = suit; } void setValue(char value) { this-> ...Show All

• SQL Server Unique Integer IDs

  Hello, I wanted to hear from you - if you've used any unique integer generation technique in the context of a disconnected smart client/local data store and have been successful with it. Any ideas/suggestions will be great. Thanks, Avinash We are using unique integer ID generation for our document ISNs. It works perfectly.

• Visual C++ msvcr80d.dll not found

  I've created a simple Win32 console application. When I try to debug it, I get the message:  "This application has failed to start because MSVCR80D.dll was not found. Re-installing the application may fix the problem." The Release version runs fine. Any idea as to what the problem could be Thanks, Jonny feuerste that's an excellent point (I'm "bottom posting" this reply so it will appear at the bottom of this thread)  I didn't know what the "use FAT32 work-around" option was as it's not even in the online help.  And the only mention of it seems to be in a Korean blog at: http: ...Show All
