• Benjamin Bradley MSFT Printing text directly to a printer (NOT as a graphic)

  I can print text if i do a e.Graphics.DrawString(......) My problem is that I am trying to print to a card printer, and usually it checks what text it is printing, and if it hits a '~' it then encodes the magnetic stripe. When i print from Microsoft word, or Access, it works fine because text is sent to the printer. But using "PrintDocument" object and drawing to a bitmap, it is unable to parse the text. Any ideas on how to print text ...Show All

• Scott S. Waschitz Multiple Threads and Synchronizing Output to a Log File

  Hello everyone... I'm working with a multi-threaded application.  I believe I have it to the point now where several different threads can write to one common log file.  Writing to the log would be used at initial startup and for an occasional exception, and is not something that would not happen very often. What I'd like some advise on is making sure the act of writing to the log is thread safe, in that when a thread writes to& ...Show All

  I am running C# 2005 beta 2. I need to persist several strings in app.config using Properties.Settings.  I will programmaticly set a label's text property with the string.  Everything works great, except I can't figure out how to localize them!    Localizing the form won't work as the label's text will change with the application's current state.

• Kevin Herbert "Layer of Abstraction" Confusion

  Hi folks, I'm trying to understand what events are, and primarily, why and when to use them, however, I'm having a little trouble understanding the subject. I hear a lot of people saying that events are another layer of abstraction, but I don't actually know what that means. I've tried Googling around, and I have found some sites that discuss it, but they seem to be talking to people who are CS graduates. Could someone explain the conc ...Show All

• gill cleeren How to efficiently read an array from a file?

  In C++, you can read directly from a file into an array without having to use an intermidiary buffer. For example, suppose I have a file containing 10000 32-bit integers. You can read from the file directly into an array of ints of the right size using "fread()". I can't find any way of doing the same thing in C#. The only ways I have found are: (1) Read each int in turn into the array via BinaryReader.ReadIn32(). (2) Read all the data ...Show All
