  • 32-Bit Compiling in XCode

    - by user15386
    I was trying to get SDL to work on my mac but kept running into mysterious errors. After some googling, I realized that my issue was that SDL compiled in 32 bits, or was 32 bits, or something, and XCode was compiling my program in 64 bits. There were some solutions, as well, but all were very technical or required arcane knowledge which my novice brain did not comprehend. So, how can I either get a version of SDL that will work with a 64 bit compiler, or tell XCode to compile in 32 bits?

  • Drawbacks of using an integer as a bitfield?

    - by Mark
    I have a bunch of boolean options for things like "accepted payment types" which can include things like cash, credit card, cheque, paypal, etc. Rather than having a half dozen booleans in my DB, I can just use an integer and assign each payment method an integer, like so PAYMENT_METHODS = ( (1<<0, 'Cash'), (1<<1, 'Credit Card'), (1<<2, 'Cheque'), (1<<3, 'Other'), ) and then query the specific bit in python to retrieve the flag. I know this means the database can't index by specific flags, but are there any other drawbacks?

  • How to convert from string to a number, and vice-versa in C++?

    - by Igal
    DEAR All I'm new to the C++, so maybe someone can say what the proper way to write a function that gets a string char (represents number) and converts it to the integer number. For example : input : Sixty five, output: 65. Maybe it should use by cin.getline() ? Well, vice-versa is little bit simlper... Thanks for advance. Igal

  • python on 32 bit

    - by Mponnada
    Hi I am running Windows XP, on 32bit. How do I install python? When I run the installation file, it gives me an error saying "installation package not supported by processor type" does python need 64 bit to execute?

  • Help me understand why page sizes are a power of 2?

    - by eric
    Answer I need help with is: Recall that paging is implemented by breaking up an address into a page and offset number. It is most efficient to break the address into X page bits and Y offset bits, rather than perform arithmetic on the address to calculate the page number and offset. Because each bit position represents a power of 2, splitting an address between bits results in a page size that is a power of 2. i don't quite understand this answer, can anyone give a simpler explanation?

  • C# reads wrong registry data on 64-bit OS

    - by baal80
    I'm working on a 64-bit Windows and my applicaiton runs with elevated privileges. I have a problem with the following very simple piece of code: myKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run"); if (myKey != null) { string[] HKLMvaluenames = myKey.GetValueNames(); } But for some reason HKLMvaluenames array is populated with values from the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run Is there a way around this problem?

  • Convert bit to boolean string in HyperLinkField.DataNavigateUrlFormatString

    - by abatishchev
    I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1} Select command of appropriate SqlDataSource returns columns of type INT and BIT (from SQL Server 2008). So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant(). How to implement such conversion in page markup?

  • How do I set Internet Explorer 64-bit as my default browser?

    - by Brian Knoblauch
    Windows Vista x64. It defaults to IE 32-bit, and will not allow me to set 64-bit as the default with the "Make Default" button. I'm currently forced to workaround by starting IE 64-bit manually, and leaving it up with an empty window. Then when links are fired from apps, they open in that 64-bit version. Problem being is that sometimes I forget and get a bunch of stuff opened in 32-bit without realizing it. Then I have to remember all the links I clicked, close ALL of them, open IE 64-bit, and put them all back in. Trying to avoid all that re-work when I forget to do the workaround. Unfortunately, all the forums I've googled that discuss this just have a bunch of people saying "don't do that" and "you don't want to do that". Yes, I do want to do this. The particular feature I use only works right in my 64-bit version, and I don't use 32-bit plugins. I fully understand the implications of what I'm doing. :-)

  • Create shortcut from vb.net on Windows 7 box (64 bit)

    - by Matt
    I am trying to create a desktop shortcut from vb.net code on a Windows 7 box (64 bit). The following code works on XP, but when run on Win7 I just get a message stating the App has stopped working: Imports IWshRuntimeLibrary Dim WshShell As WshShellClass = New WshShellClass Dim MyShortcut As IWshRuntimeLibrary.IWshShortcut ' The shortcut will be created on the desktop 'Win 7 MyShortcut = CType(WshShell.CreateShortcut("C:\Users\Public\Desktop\iexplore.lnk"), IWshRuntimeLibrary.IWshShortcut) 'MyShortcut = CType(WshShell.CreateShortcut("C:\Documents and Settings\All Users\Desktop\iexplore.lnk"), IWshRuntimeLibrary.IWshShortcut) MyShortcut.TargetPath = "C:\Program Files\Internet Explorer\iexplore.exe" 'Specify target app full path MyShortcut.Description = "IE" MyShortcut.Save() Any thoughts or better ways to create a shorcut from code on a Win7 box?

  • Breakpoints are ignored when debugging in Visual Studio 2008 on 64-bit system

    - by Arnold Zokas
    I'm trying to debug an ASP.NET web application in this environment: Windows Server Standard 2008 SP2 x64 Single-core CPU 4GB RAM Visual Studio 2008 with Remote Debugger SP1 .NET 3.5 Web Application running in IIS in 64-bit mode The code I am trying to debug is a simple event handler with some basic sequential code. What I observe is that breakpoints get randomly ignored and VS often exits debug mode when I try to step through the code. The code is compiled in debug mode. I've tried all the usual steps: iisreset, reboot VM, rebuild solution, reinstall Visual Studio. Any ideas?

  • JSON htmlentities javascript

    - by Wessel Rossing
    Hi! I am using an XMLHttpRequest to POST a JSON string to PHP. The JSON object is created in JavaScript and using the JSON2.js from json.org to create an JSON string representing the object. JSON.stringify(object); Whenever the object contains a string which has a special character in it, e.g. é, JavaScript does not give any error but PHP receives an empty array [] Is there a JavaScript function which produces the exact same resutls as the PHP function htmlentities() The data is send via POST, so the following functions escape() encodeURI() encodeURIComponent() are a bit overkill. Thanks!

  • determine if parity bit representation in MIPS

    - by Hristo
    Is there some instruction in MIPS that will determine the parity of a certain bit representation? I know to determine whether a "number" has an even parity or an odd parity is to XOR the individual bits of the binary representation together, but that seems computationally-intensive for a set of MIPS instructions... and I need to do this as quick as possible. Also, the number I'm working in is represented in Grey Code... just to throw that in there. So is there some pseudo-instruction in MIPS to determine the parity of a "number" or do I have to do it by hand? Thanks, Hristo

  • OPOS not working on 64 bit system

    - by Blair Mahaffy
    Anyone have experience with OPOS? I can't get my app to recognize the LDNs for the devices running on a 64 bit machine. I've got down to the point where I know that the OleforRetail stuff is now under Wow6432Node in the Registry. I suspect the common controls can't find the LDN because of this. Is there any kind of workaround? Failing that, is there a centralized OPOS development forum somewhere? BTW: I work with the common controls supplied by Monroe Consulting. Thanks!

  • Best way to represent Bit Arrays in C#??

    - by divinci
    Hi all, I am currently building a DHCPMessage class in c#. RFC is available here : http://www.faqs.org/rfcs/rfc2131.html Pseudo public object DHCPMessage { bool[8] op; bool[8] htype; bool[8] hlen; bool[8] hops; bool[32] xid; bool[16] secs; bool[16] flags; bool[32] ciaddr; bool[32] yiaddr; bool[32] siaddr; bool[32] giaddr; bool[128] chaddr; bool[512] sname; bool[1024] file; bool[] options; } If we imagine that each field is a fixed length bit array, what is : The most versitile Best practice way of representing this as a class??? OR.. how would you write this? :)

  • DBD::Advantage and 64-bit Perl - Always 6060

    - by WarheadsSE
    I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title
