A dll can be created in C# by creating a Class Library project if that's what your asking.

Whoever wrote that dll is not the person to learn from though, passing a Form as a parameter is bad enough, but into a BusinessLayer OMG | :OMG:

Use Reflector and hope the assembly is not obfuscated.

If it's a .net assembly, you may be able to disassemble it using Reflector[^]. To create your own, just choose Class Library when selecting the project type when creating a new project.

Printer sometimes hangs [modified]

With one of my customers I have this really weird problem. I just describe it in a bunch of facts, to keep it short.

* It's an application that communicates with a weighbridge and visualises the current weight of the brigde (serial communication RS232) --> the scale sends over the weight continuessly
* The customer can make a ticket containing information about the transporter and the kind of product that's been transported
* When the ticket is saved, it is also printed on the connected USB HP LaserJet (P1006) printer
* pc/dev configuration: Windows XP SP3, VS2008 (C#)

The problem is that sometimes for an unknown reason, the printer does not print. The ready-LED keeps blinking but nothing happens. The application continues to work normal. When this happens, the customer opens the print cartridge cover and closes it again and then the printer starts the print job.

It's a problem that I've seen happening but I can not reproduce it.
it's not related to the data (if you print the ticket afterwards, no problem)
It's not related to hardware (did replace PC, Printer (from other brand), USB Cable without success)
I did rewrite my app so that the serial communication happens in a backgroundworker and generates an event only if the current weight is different from the previous value (this delegate for this event updates the GUI)
I did create also another backgroundworker to create and print out the document (System.Drawing is used to do this; did use Crystal Reports in the past but same problem there)
The data is stored in XML files

What I also did was unchecked the flag 'allow the computer to turn off this device to save power' for all USB Root Hubs. --> I don't have any results of that yet, since I did this just yesterday.

At this moment, I don't know where to search anymore. I can not reproduce it, I can not find any kind of pattern in the occurence of this problem, I can not tell what might cause the problem.

In summary: is there anybody with some suggestions

Sounds like an issue with the printer itself - possibly there's a bug in its software that you're hitting.

System.Collections.Specialized.StringCollection Question

Hi all,

When making use of the settings.config file, one of the types that one can make use of, is System.Collections.Specialized.StringCollection, which brings me to my question; which control can one use to link to the application setting to diplay these values? Confused | :confused:

Many thanks in advance

Any collection is a valid data source for a data bound control, I thought.

Yes, I am aware of that, but is there a way to make use of the property binding to set the value in the control?

It's a collection of strings, you'd bind to the string, wouldn't you ?

The GridView control is what you need. And, probably, a basic winforms book.

Sounds like a good plan. Reading a half million records at a time is obviously insane. Did you want an award, or did you have a question ?

You're asking for the root node. This is poorly formed XML, to say the very least. Perhaps XMLTextReader demands a higher standard ? I don't know, but if you use XMLDocument, I'd expect the root contents to give you what you want. Your XML format sucks tho.

Adding to what CG said,

XML parser will take <b> as a new node rather than taking as the content of <para>. You need to read about CDATA[^] section and create a well formed XML.
