• .NET Development XSLT works in .Net 1.1 but fails in .Net 2.0

  We have an application compiled with .Net 1.1.  It uses System.Xml.Xsl.XslTransform.  the following code works with .Net 1.1 <xsl:copy-of select="$style/ap:OneImage"/> if $style is empty or if $style contains an element.

• Visual C# Raw commands to Parallel Ports on USB/PCMCIA adapters

  Hello all (I hope this didn't post twice,) I'm developing C# software to manage two separate parallel-port relay control boards. I can currently contol them individually just fine using standard I/O port access using inpout32.dll as long as I use the built-in parallel port on my laptop. The problem is that I need to control two parallel ports. My laptop only has one built-in port and I need it to work with a laptop (laptop and desktop manufacturers are increasingly omitting parallel ports these days.) I've purchased both a USB-to-Parallel adapter and a Dual-Parallel port PCMCIA adapter (the Koutech CBP220.) The problem I have is tha ...Show All

• .NET Development Passing a ascii byte array as System.String to a COM BSTR param

  I have a VC6 ATL COM Object that accepts a BSTR as an input parameter in one of its methods. The COM Object expects an ascii buffer to be embedded in the body of this BSTR and uses a call to SysStringByteLen to dynamically create an appropriately sized single byte char array for holding the extracted contents based on the results obtained from interrogating the size prefix of the BSTR. The COM interop wrapper generated from this dll defines this parameter as a System.String that gets marshalled as UnmanagedType.BStr. I am trying to use this method from managed code (C#) but am having difficulty creating an ascii encoded string parameter ...Show All
