Extract All Characters In Unicode, UFT8, Iso-8859-1 To 9 Etc To A List Or Array In VB?
Jan 11, 2010How do I Extract all Characters in Unicode, UFT8,iso-8859-1 to 9 etc to a list or array In VB?I have a SQL Database of which contains values from 51 languages. I need to detect which ISO-8859-? Was used to encode the string value. For example Turkish Characters i.e. "Ö Ş ş ğ ü Ç" Once I have the correct ISO, I need to convert the Chars with-in the string to Unicode using only if the string value contains values that are not UFT7, and convert the string to HEX?The reason I need to detect the ISO etc is because we are sending SMS, of which jump from 160 characters to 70 if a special characters are used, i.e. "Ö Ş ş ğ ü Ç" Is there a simple way to extract the ISO-8859 Character Set to a Array etc, or is there a simple way to check if the character exists with a ISO-8859 data set?
View 5 RepliesListbox Data Extract After Data Entry & Sort
Sep 26, 2011I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]
