data-conversion

I want to display numbers in a std::vector<unsigned char> on a screen, but on its way to the recipient, I need to stuff these numbers into a std::string . Whatever I tried ( atoi , reinterpret_cast , string.c_str() ...), gave me either a nonsense, or a letter representation of those original numbers - i.e. their corresponding ascii characters. So how do I easily (preferably standard method) convert vector<unsigned char> {1,2,3} into a string "1-2-3" ? In the Original Post (later edited) I mentioned, that I could do that in C# or Java. Upon the request of πάντα ῥεῖ to provide example in C# or

I have a source flat file with values such as 24.209991, but they need to load to SQL Server as type money. In the DTS (which I am converting from), that value comes across as 24.21. How do I convert that field in SSIS? Right now, I am just changing the type from DT_STR to DT_CY, and it gives a run error of 'Data conversion failed. The data conversion for column "Col003" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".' Do I use a Data Conversion task? And then what? I've also tried setting the source output column to DT_NUMERIC,

I'm trying to make my dataset correspond to this example: var family = [{ "name" : "Jason", "age" : "24", "gender" : "male" }, { "name" : "Kyle", "age" : "21", "gender" : "male" }]; I have a Map<String, HashSet<String>> of Names and unique alpha-numeric values correponding to specific entities to which those names could refer, let's call these entry items "IDs". So for instance, Fyodor Mikhailovich Dostoyevsky would perhaps be related to the ID Q626 , because that's a very specific reference, there aren't many widely known figures with that name. Whereas, Bush might be attached to G027 , Q290

I have a byte array read over a network connection that I need to transform into a String without any encoding, that is, simply by treating each byte as the low end of a character and leaving the high end zero. I also need to do the converse where I know that the high end of the character will always be zero. Searching the web yields several similar questions that have all got responses indicating that the original data source must be changed. This is not an option so please don't suggest it. This is trivial in C but Java appears to require me to write a conversion routine of my own that is

I transfer message trough a CAN protocol . To do so, the CAN message needs data of uint8_t type . So I need to convert my char* to uint8_t. With my research on this site, I produce this code : char* bufferSlidePressure = ui->canDataModifiableTableWidget->item(6,3)->text().toUtf8().data();//My char* /* Conversion */ uint8_t slidePressure [8]; sscanf(bufferSlidePressure,"%c", &slidePressure[0]); As you may see, my char* must fit in sliderPressure[0] . My problem is that even if I have no error during compilation, the data in slidePressure are totally incorrect . Indeed, I test it with a char* =

I am using an API which requires a date parameter as a number of seconds, an int . My problem is that I currently store this time in java.util.date and I was wondering if there is some way to convert the java.util.date variable to seconds so that I can fit it into the int parameter which the API requires? import java.util.Date; ... long secs = (new Date().getTime())/1000; ... Please see - http://docs.oracle.com/javase/6/docs/api/java/util/Date.html#getTime() java.util.Date.getTime() it returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object. java
