C# :: SQLException - Error Converting Data Type Varchar To Numeric
Oct 22, 2014
I am writing a simple program to suck in a txt file then pump it into sql.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Data.OleDb;
using System.Data.SqlClient;
[Code] ......
How I can get past this error and get the data into sql? I read a couple articles on .tag but not sure I understand what to do.
I program unix sokcet programming , and part of my code is ti open file from server and open it , but i surprised with this wierd error i dont have any reason for it ?
do { printf("Edit the entry's cellphone number:"); scanf("%s", addressbook[4][num]); length = strlen(addressbook[4][num]); //gets the length of the input (should be 10) //checks if the input is composed of 11 elements wherein the first 2 are 0 and 9 respectively for(i=0; i<11; i++){
I'm trying to send out a message to all classes that are a Director. The only issue I'm running into is converting the typeof the object so the receiever parameter can hold it.
I tried using the Activator class to instantiate the object but was running into issues with getting it to accept the object passed. Here's what I had had:
Originally I had to create a simple integer palindrome program that looped while the user entered 5 digit inputs (entering -1 stopped the loop). I did this using a conversion to string, reading the length to determine if the length was valid, and then reading the string forward and backwards inside of a while loop. (snippet below)
while( digitsEntered != -1)//Allow user to quit by entering -1 to end the loop { ostringstream convert;//conversion stream convert << digitsEntered;//converted text from number goes in the stream convertedString = convert.str();//store the resulting conversion to convertedString
[Code] ....
The next stage of this program was to do the same thing with strings instead of integers. However, the option to end the loop by entering -1 is still a requirement.
I think the way to do this is to first determining whether the input is a string or an integer, and if it is a string then read it and if it's an integer determine if it's -1. However, whenever I write code to do this, it converts strings to 0 so the string is not stored and cannot be read to determine if it is a palindrome. Is there a way to determine the type of input without converting it into a different type i.e. read string and then keep string or read number and keep number?
I am tying to convert an int to a char. Below is an example of the code that I have but I am getting an error('=':left operand must be l-value). I am not seeing a problem with the code.
int num = 5; char temp[2]; char final[2]; itoa(num, temp, 10); m_pRes->final = temp;
I'm trying to find angles A,B,C using law of cosines and I want the answers to be in degrees and the formula to convert the answer to degrees is angle*PI/180. However the answer does not convert to degrees what am I doing wrong?
Code: #include "stdafx.h" #include <iostream> #include <iomanip> #include <cmath> #define PI 3.14 using namespace std;
I'm not the best at C but I'm trying to write a C function that basically opens a text file with assembler language does a syntax error check on it and then converts the binary data into hex.
This is my code so far:
Code:
#include <stdio.h> #include <string.h> int main(void) { FILE*fname; char prompt; char filename[15]; char text[100]; printf( "Please enter the name of the file you wish to open: " );
I need to convert characters in a input file to numbers in output file and display both the characters and numbers in a console window.Only 7 numbers can be displayed, the rest needs to be dropped.The input file contains the following data, with one number per line:
CALL HOME GET LOAN Hi THERE BYE FOR NOW
For example, once the first number in the input file has been processed, the console window should display the following: CALL HOME 225 5466.
The output file should now also contain the number: 225 5466
Currently my console is displaying the following:
Enter the input file name. infile.txt
Enter the output file name.
outfile.txt 2554663Invalid Input 4385626Invalid Input 4Invalid Input 84373Invalid Input 293367669Invalid Input 4357637277CALL HOME GET LOAN Hi THERE BYE FOR NOW
#include <iostream> // for screen/keyboard i/o #include <fstream> // for file #include <cstdlib> // for exit using namespace std; void openFile(ifstream& infile)
I have a Polymorphic class and some child classes, of which I need to make multiple instances of, using a list container. I've set the key type to be a unique pointer of the polymorphic class, and the values of each element pointing to a New Child instance, like so:
The only problem is that when I try to push_back a new element, I get a compiler error, saying "No instance of overloaded function".Should I try and create a pointer object on it's own and push back that object as an element, it will work fine:
I am getting the error on the implementation of my class name. The error is coming from my parkingControl.cpp 'ParkingControl parkingControlMenu;'. I have used this implementation fine before, but once I added a new main it stopped working. Below is my code.
I am trying to write a program that reads in an XML file, parses it and prints out information about each tag. I am getting the following errors when trying to build the program:
Parser.cpp:24:1: error: 'Parser' does not name a type Parser::getXMLData() { ^ Parser.cpp:120:1: error: 'Parser' does not name a type Parser:rocessXMLData(
When declare and assign an instance of a user-defined struct in a function. And the struct (theStruct) is not declared in the same header file as the function (theFunction). Like this:
files: "A.h": declares the struct in a class (theClass) "A.cpp": implements the struct "B.h": declares the function "B.cpp": implements the function, error here
I think making the instance (inst) a reference might solve this. But the instance is assigned to a return value from a function (returnFunc). Like:
void theFunction() { ... theClass::theStruct inst = returnFunc(...); //returnFunc() returns an instance of theStruct //the error is at 'inst' ... }
I'm trying to learn recursion, and I'm using a simple array to experiment with it, but I have a couple of annoying errors that I don't understand why they're there. Here's the code:
Code: #include <cstdlib> #include <iostream> using namespace std; int largest(const int arr[], int lowerIndex, int upperIndex) { int max;
[code]....
Now try to print the array backwards:
//Use a recursive algorithm to find the largest element in arr: int largest(arr[], lowerIndex, upperIndex);//error: expected an expression return 0; }
I've been writing the math functions for a 3d game and tried compiling it at about 30 functions in. I get this error related to my pointers to my structures. it affects almost everything in all my functions (as youll see by looking at how i do the math in the function below). The compiler gives me the error
"error: dereferencing pointer to incomplete type"
on all my struct Type4D pointers but referencing the values in my struct TypeMatrix4X4 using pointers seems to work fine i think (it doesn't seem to complian explicitly about it. so here is the important code...
I am having trouble with this program I get the error dereferencing pointer to incomplete type in the populate function I am using BloodShed's Dev C++ compiler v4.9.9.2 I copied this program out of a book because I was having a problem with a linked list in a similar program. I think there is a problem with the compiler not supporting these types of pointer's in a function.
