• Game Technologies: DirectX, XNA, XACT, etc. XNA Book ( In Progress )

  For reasons I cannot exactly put into words, I’ve decide to write a (free) book about how to use XNA.   It is defiantly a work in progress and thus far only includes two chapters and associated source code. I truly hope that my work is advantageous to some people out there. I am in part doing this as a practice towards writing technical documentation.   I am not accomplished in writing instructions for other people that may not have the same level of technical skill sets as myself.   I hope that with this book I learn a whole lot and more in that regard. Granted, if you are a diehard game programmer, what I have written is probably not for you, at least, not yet! Yet I would value your input.   If you feel like c ...Show All

• Windows Forms Auto resize columns in TableLayoutPanel

  I have a TableLayoutPanel with one 1 row and 9 columns. The TableLayoutPanel has these properties set at Design Time AutoSize = True AutoSizeMode = GrowAndShrink All 9 columns have a Size Type of Percent equally set to 11.11%. Row1 (the only row) has a Size Type of AutoSize. All 9 cells contain a button with it's Dock Property to Fill . At runtime I need to hide some columns and have the remaining columns equally grow to fill the space. How can this be done Following JRQ's suggestion I wrote the following method and it works exactly how I need. Here is the code in case it helps anyone.

• SQL Server BCP fails with 134 columns

  I'm trying to BCP from a csv file to a table, both have 134 columns. The error message coming back from BCP "SQLState = 37000, NativeError = 170 Error = [Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near '1'." By reducing the number of columns in both csv file and table to around 20 column , the bcp call will work and the data will load into the table.Here's a sample that shows the problem The command line I'm using to call bcp:- "C:\Program Files\Microsoft SQL Server\80\Tools\Binn\bcp.exe" em.dbo.mytable1 in c:\temp\_rrs\datafile.csv -S SQL_SERVER_NAME -U username -P password -t "|" -c -F 2 The version of BCP this is using :- 8.00.194 on SQL Server 2000.

• Visual C++ <windows.h> Interferes with System::IO::Directory::GetCurrentDirectory();

  Including windows.h in a managed project overrides System::IO::Directory::GetCurrentDirectory();, which is very annoying: rootFolder = System::IO::Directory::GetCurrentDirectory(); //'GetCurrentDirectoryW' : is not a member of 'System::IO::Directory' How can this be prevented This seems to be the only function in wondows.h that gets confused with System::... If you do not need the GetCurrentDirectory function from windows.h , maybe you can just un-define it: #include <windows.h> #undef GetCurrentDirectory I hope this makes sense. ...Show All

• Visual Studio Build intellisense documentation (i.e. have ability to strip internal members from xml doc)

  NDoc had the ability to produce intellisense output from the raw intellisense xml doc produced by the compiler. There was the option to remove all internal members from it, which was really useful. I'm writing .NET components, and all classes that I do not want to expose to the public are internal, hence the documentation of those classes should not appear in the intellisense docs, because it could e.g. reveal sensitive information about used algorithms, and it bloats the intellisense doc unnecessarily. Is this possible with Sandcastle yet Couldn't find the option so far. (If not, please do not hesitate to cram it in the February CTP :-) ) Thanks, Wout I think it's a separate build type in NDoc.

• Visual C++ In search of the lost Form1.cpp file

  I just tested making a Windows Form in C++/CLI for the first time. I've only used C++/MFC before where (most) functions are declared in a header file and defined in a cpp-file. Not so in a Windows Form class it seems. It seems that all functions in a Windows Form class are supposed to be inline. Is that true Please help me clarify this paradigm shift (if there is one).

• Smart Device Development Create meeting requests in inbox

  Hi, We are trying to create meeting requests in the inbox via MAPI. So basically what I do is create a message, set the PR_MESSAGE_CLASS type to IPM.Schedule.Meeting.Request. So far so good, the message shows up as a meeting request and the menu extends so I am able to select 'Accept' or 'Reject'. What I don't know is how is it possible to automatically add the appointment data ( VCalendar, ICalendar ) in the message itself so when I click on 'Accept' the appointment will be added automatically to the calendar. That is not happening right now. I was checking one of the original meeting requests sent by Exchange and the VCalendar/ICalendar ( actually named as 'meeting.ics' ) is stored in there as an attachment. But ...Show All
