• Visual C# SI Abbreviation Significant Number String Formating on Decimal Resolution

  Hi all, Let say I have a string formed from a double value. After a converting function to display desired quantity of significant number with SI Abbreviation. e.g. The original value is a double (12345.678). [1 significant number] : 300 m (string) [2 significant number] : 310 m (string) [3 significant number] : 312 m (string) [4 significant number] : 312.3 m (string) The problem here is that I must do the decimal resolution placing on the string only after which I get out of conversion process. The hard part is that the SI Abbreviation is attached on the output string after the significant number conversion function. I do not have access to modify the significant number conversion function. So, I must carry on modifying the output string ...Show All

• Visual C++ How do a create a new text file, and how do I insert an eof into it?

  Hi, I'm looking to create a new text file. I am in second term C++ so we're not using the MFC or anything. We have covered opening, reading, closing ifstream and ostream objects from fstream.h , but nothing about how to create a file if one's not there. Is this possible Also - anyone know how to insert an eof into a file through a text editor or something in Windows I am given to understand the eof flag is represented by a ctrl-Z but I can't insert this using textedit. In the mean time I'm using a pipe symbol '|' as my eof flag which is much less elegant. Thank you o wise sages of the code.   dangrmous wrote: You asked me in your last comment the following, and I quote directly: " What happens if you use ofstrea ...Show All

• SQL Server Problems with date formats

  The date fromat in my country (Australia) is DMY. It seems to be quite difficult to prevent the month and day being swapped around. I had a case recently where we generating a list of dates to be presented in the report server UI (User Interface) as a list box for a parameter selection. We fixed the problem in the data set (on the data tab) by using "SET DateFormat DMY" only to find that the month and day were still swapped around in the UI list box. If this was just a presentation issue we could live with it but it turned out that the value read into the parameter was incorrect (the day and month were actually swapped). To fix the problem, we had to chnage the data type to VarChar() in the data set query, using Convert() to force ...Show All

• Smart Device Development Reading Application-Config in CF 2.0

  Hi there, is there any chance to read the data stored in a .config-file with CF 2.0 The namespace "System.Configuration" is completely missing in the Objectbrowser! Any chance to get the code without self-coding thanks in advance and best regards Reiner PS.: In the good old days of Win32-Programming my nightmare was the "ERROR_ACCESS_DENIED"-error! Nowadays this is the "NotSupportedException", which I get (at least) 10 times a day!!!! Configuration file is just an XML - open it as XML in DOM or XmlTextReader and read what you need. It's not without coding, but fairly easy. OpenNetcf.org has some classes in OpenNETCF.Configuration namespace to simplify t ...Show All
