Hello everyone,
My question may be a repeat of other conversion question but I feel mine is different.
Here goes... [simplified example].
public class DataWrapper<T>
{
public T DataValue{ get; set; }
public DataWrapper(T value)
{
DataValue = value;
}
public static explicit operator DataWrapper<T> (T value...
I've been trying to figure out how to convert a string to a String in Visual Studio 2005 with no luck.
Here is the relevant code:
#include <string>
using namespace std;
#using <System.dll>
using namespace System;
string test = "a test string";
So I'm trying to convert test into a String^ to use inside other .NET classes, can anyone ...
Hello!
Please take a look at the following code:
Public Sub Method(Of TEntity As EntityObject)(ByVal entity As TEntity)
If TypeOf entity Is Contact Then
Dim contact As Contact = entity 'Compile error'
Dim contact = DirectCast(entity, Contact) 'Compile error'
Dim contact = CType(entity, Contact) 'Compile er...
I need to convert a Session object to an IOrderedQueryable and came up blank. I've thought of creating a wrapper, but its not working properly. Basically, I am pulling a Linq query and would like to store it so that I don't have to pull it each time I visit. There are up to 7-10 parameters per user so it's not something that's great for ...
I have created a custom data type enum like so:
create type "bnfunctionstype" as enum ( 'normal', 'library', 'import', 'thunk', 'adjustor_thunk' );
From an external data source I get integers in the range [0,4]. I'd like to convert these integers to their corresponding enum values. How can I do this? I'm using PostgreSQL 8.4.

Hello friends,
I am absolutely new to Java and Blackberry development. I've started learning Java and Blackberry development. I just created sample BB app, which can allow to choose the date.
DateField curDateFld = new DateField("Choose Date: ",
System.currentTimeMillis(), DateField.DATE | DateField.FIELD_LEFT);
After choosing the ...
The following program shows the weird double to int conversion behavior I'm seeing in c++:
#include <stdlib.h>
#include <stdio.h>
int main() {
double d = 33222.221;
printf("d = %9.9g\n",d);
d *= 1000;
int i = (int)d;
printf("d = %9.9g | i = %d\n",d,i);
return 0;
}
When I compile and run the program, I see:
g++ test.cp...

I have a query in MS Access which creates a table from two subqueries. For two of the columns being created, I'm dividing one column from the first subquery into a column from the second subquery.
The datatype of the first column is a double; the datatype of the second column is decimal, with scale of 2, but I want the second column t...

I have a very large table in MySQL. I'm using a CHAR(32) field which contains an MD5 as a string of course. I'm running into an issue where I need to convert this to a decimal value using MySQL. A third party tool runs the query so writing code to do this isn't really an option.
MySQL does support storing hex values natively and convert...
First my context is that of a compiler writer who needs to convert floating point literals (strings) into float/double values. I haven't done any floating point programming the last 15 years so i'm pretty sure this is a total stupid newbie question.
double res;
errno=0;
*res = strtod((const char*)literal,NULL);
if (errno==ERANGE) thr...
Hi,
I'm trying (with Dozer) to convert a JAXB DTO to a POJO (well, actually, to a JPA-annotated Hibernate entity before persisting it). The problem right now is that right now Dozer does not seem to convert elements from the JAXB JAXBElement<> type to the JAXBElement.getValue() type. So, for example, a JAXBElement s is translated to th...
I like to initialize 2-dimensional arrays as vector<vector<int> >(x,y). x is passed to vector<vector<int> >'s constructor and y is passed to vector<int>'s constructor, x times. Although this seems to be forbidden by C++03, because the constructor is explicit, it always works, even on Comeau. I can also call vector::assign like this. But,...
Hi all,
I've searched and searched stackoverflow for the answer, but have not found what I needed.
I have a routine that takes an unsigned char array as a parameter in order to encode it as Base64. I would like to encode an STL float vector (vector) in Base64, and therefore would need to reinterpret the bytes in the float vector as an ...
I'm making a generic MVC viewer/editor for data objects I've designed, modeled after ActiveRecord.
The data objects are completely generic, they can have primary keys that are strings, ints, int16s, whatever the database uses (the persistence layer at this organization uses all sorts of datatypes for primary keys and I want this MVC "br...
I am sick of encapsuling each call of asType with try/catch block like :
def b = ""
def c
try {
c = b as Integer
}
catch (NumberFormatException) {
c = null
}
println c
instead I would like to write in my code the following:
def b = ""
def c = b as Integer
and if b is not well-formatted, then I want to have null be assigne...

Hi there,
I have to work with a legacy system based on SQL Anywhere 5, db access layer is in C++ using embedded SQL. The problem I have is not really a C++ problem, but embedded SQL forces us to SQL statements which cannot be dynamically generated. There are many tables containing a lot of columns having the datatype double. Though the ...
