I am porting an existing application to C# and want to improve performance wherever possible. Many existing loop counters and array references are defined as System.UInt32, instead of the Int32 I would have used. Is there any significant performance difference for using UInt32 vs Int32? ...
I have a property of type uint on my entity. Something like: public class Enity { public uint Count {get;set;} } When I try to persist that into the SQL Server 2005 database, I get an exception Dialect does not support DbType.UInt32 What would be the easiest way to workaround this. I could for example store it as long in the ...
Hello, In C#,I'm using Blowfish.NET 2.1.3's BlowfishECB.cs file(can be found here) In C++,It's unknown,but it is similiar. In C++,the Initialize(blowfish) procedure is the following: void cBlowFish::Initialize(BYTE key[], int keybytes) In C#,the Initialize(blowfish) procedure is the same public void Initialize(byte[] key, int ofs,...
Hi, How shall sort this in ASC order? I got List<List<UInt32>> full of records of List<UInt32> and I want those records to be sorted according to the first column in each record - the column is UInt32 number. So: I have List of: new List<UInt32>: 32,1,1,1,1,1 new List<UInt32>: 22,2,2,2,2,2 new List<UInt32>: 32,1,1,1,1,1 new List<UIn...
I'm trying to call SendMessage with an uint parameter from Java, but I can't convert int to uint. I can't change the uint parameter in SendMessage because it is a windows function. Is there some way of doing this? Background: I'm actually using Processing, and I'm following the following tutorials to access user32.dll: http://processing...
- (void)playAlarmSound:(NSTimer *)theTimer { static SystemSoundID soundID/* = 0 */; // ? if (!soundID) { soundID = [Utilities createSystemSoundIDFromFile:@"beep" ofType:@"caf"]; } ... } Is SystemSoundID (which is a UInt32) automatically assigned 0? or should I explicitly assign it? I have to do it this way and t...
What is the UInt32 datatype in VB.NET? Can someone inform me about its bit length and the differences between UInt32 and Int32? Is it an integer or floating point number? ...
What is the difference between Int32 and UInt32? If they are the same with capacity range capabilities, the question is for what reason UInt32 was created? When should I use UInt32 instead of Int32? ...
What is the best way to map UInt32 type to sql-server int type with NHibernate. The value is a picture width/height so negative value are not make sense here. But maybe I should use int because NHibenate doesn't support unassigned ints. ...
i have declared a variable as uint32_t num; when i take input for this variable i.e cin>>num; cout< when i run this program, i gives num value as 12345678, it works fine & give cout. but when i give input as 1234abcd. it creates problem & displays only 1234. please suggest solution to resolve this problem. ...
Possible Duplicate: Should I use uint in C# for values that cant be negative? Suppose that the MaxValue of (roughly :) ) 2^31 vs 2^32 does not matter. On one hand, using uint seems nice because it is self-explanatory, it indicates (and promises?) that some value may never be negative. However, int is more common, and a cast is...
Hello overflow, i have some low level image/texture operations where 32-bit colors are stored as UInt32 or int and i need a really fast bitwise conversion between the two. e.g. int color = -2451337; //exception UInt32 cu = (UInt32)color; any ideas? thanks and regards ...
I'm working with legacy embedded C code which defines the types uint8_t, uint16_t and uint32_t in a header file using the typedef keyword. For discussion, let us say the file typedefs.h contains these definitions. In my new C source module, I include stdint.h. I also include other header files which include typedefs.h somewhere in t...
