• Visual FoxPro can't reindex 82,000 kb file

  Let me begin by thanking you for the help.  I am not a avid foxpro programmer.  I have a table in my database that has been acting up the past few weeks, but usually a reindex would fix the problem.  Today It won't let me reindex.  I type reindex and press enter and instead of getting the counter on the bottom right hand corner.  It does absolutely nothing.  If I delete the .cdx file and try -- still nothing.  If i move a .cdx file in from a backup -- still nothing. I am at a loss!  try this: Use("yourtablename") exclusive delete tag all index on whatever tag whatever ...Show All

• Windows Forms Visual Studio Error or Code Error: Form Inheritence.

  Hi all. My problem stems from form inheritence. Everything was fine with my program until I created forms that inherited from a custom form. The first signs of things going wrong was when I would try and view the child form in designer mode; it would show a write screen saying there was a reference to an object that hadnt been created. I fixed the problem by ignoring everything in the parent folders load form if in designer mode, but now every time i view the child form in design mode visual studio seems to start my program but its more like its showing the design form in full screen mode: Child Form: public class frmTableView : ...Show All

• Visual Basic How to get Stings of 8 bit Chars from Comm Port

  I am using an MSDN RS232 sample VB code in VSTS2005 to read and write from/to the Com1 port. But the example uses System.Text.ASCIIEncoding.GetString which only handles 7-bit ASCII characters, not 8-bit. I don't see any Encoding format that will return strings of simple 8 bit bytes of characters from the Serial port unmodified. What Encoding code can I use for simple strings of 8-bit bytes so that I can handle 8-bit binary data from the COM1 port properly How can I convert Byte Array into Strings of 8 bit characters Thanks for your Help. No, that's not quite what I need. I don't want to convert th ...Show All

• Visual C++ How do you develop an interface for an existing C++ program?

  Hello Everyone, I have a large and complex program, which to be honest I dont fully understand, that I have to develop an interface for. I understand how the program works to an extent, but the level of C++ used in the program is way beyond me. It has to do with genetic programming, programs writing programs, so I dont think that im going to be learning how to do that anytime soon. Although I am alot better with VC++ than C++ and can comfortably develop simple interfaces to perform a variety of functions. I have been working my way slowly through sams VC++ for beginners and have learned quiet a bit, although I am still mos ...Show All

• Software Development for Windows Vista Rules which reference Activity properties in XOML only workflows

  Has anyone been successful in creating and executing a rule that refers to an property of an activity which was dropped onto the workflow at design time in a XOML only workflow. In our scenario, we have a hosted designer which outputs XOML only workflows. In the designer, we can drop activities on to the surface and reference activity properties from anywhere on the workflow. HOWEVER, if we write a rule (in a policy or condition) which accesses a property on a dropped on activity, the workflow fails validation. It appears that it can't resolve the child activity types at validation time. When creating the workflow with XAML Activatio ...Show All
