I got bit again by a nasty string concatenation problem in VFP. This isn't the first time I've hit this particular issue and I've known about it for years, but it's one that's easy to miss and so from time to time I hit it again. The problem occurs when you have string concatenation code that involves an expression that returns results from a function and where the function often returns a large amount of text. |

IIS 7 provides a number of request filtering features by default and at least one of these options - blocking of URL access to the bin directory - potentially affects older Web Connection applications that aren't built using script maps. |

Circular references in Visual FoxPro are a bitch! If you've ever been hit by a creeping memory leak you've probably experienced the circular reference problem in VFP. There are ways to deal with the immediate problem but they require a bit of discipline and even then it's still possible to end up with circular references.

There are still a host of questions out there regarding Web Connection 5.0's Web Control Framework. In this post I address a few recurring questions and contrast with classic Web Connection to clarify where the Web Control Framework fits. |

Watch out for VFP 9 SP2 not getting properly registered on your machine if you're running COM servers. Apparently VFP 9 SP2 installations often fail to register the VFP9r and VFPt runtimes properly which causes some problems with VFP's internal COM objects. |

| 02/17/08 08:19pm | Showing Windows AutoComplete Dropdowns in Visual FoxPro
Getting the Windows behavior to show dropdown windows for File paths or MRU URL lists is a common feature in Windows, but it's not quite intuitive to add this behavior to Visual FoxPro because it requires an HWnd value that FoxPro Controls don't possess. Here's a way around this problem using the RichText control and some tricks to make it display properly in a FoxPro form. |

| 09/19/07 05:56pm | Finding hung References in Visual FoxPro
One of the big problems with Visual FoxPro development is the issue of hung references because Visual FoxPro's garbage collector is often not smart enough to deal with circular or often even simple multiple references. It's not easy to find exactly what's hanging but if the object in question has code in the Destroy method you can point get the debugger to step into it. |
| 09/09/07 01:50am | Should you upgrade to Web Connection 5.x?
Several people have asked me recently whether they should upgrade to Web Connection 5.x because they don't want to use .NET. There's some misconception about what Web Connection 5.x represents in relation to .NET and in this post I'll try to clear up the relationship and talk about why Web Connection 5.x is a worthy update even if you don't use the new Web Control Framework. |
