| | Let me start by mentioning that this is C and not C++. this is wrong in your code: [code] sprintf(sqlString,"INSERT INTO myTable('StaffID','Name','Birthday','PhotoURL') VALUES('%d','%s','%s','%s')",'3','playboy','10-19-2009','c:\myphoto.jpg'); [/code] Strings should be surrounded with double-quotes, not single, so "playboy" instead of 'playboy' etc. Also use a forward-slash when using filepaths (c:/blah). The backslash indicates an … |

 | isdigit expects only 1 character, but you're giving it an char-array. That's because strtok returns an array of characters. See [URL="http://www.cplusplus.com/reference/clibrary/cstring/strtok/"]this page[/URL] |

| | No. The array 'accUse' will only exist within the scope of the function 'trArr'. You should read [URL="http://msdn.microsoft.com/en-us/library/b7kfh662(VS.80).aspx"]this[/URL].
