C# :: Avoiding Hardcoding Column And Table Names
Jan 6, 2015I've just started working on a Database application and maintaining a previous developer's code, one thing I see is that column and table names are hardcoded throughout the code which is something I'd like to avoid. To me it seems like a practice that is prone to spelling mistakes reaping havoc across the application.
Some I've looked at include:
Constant strings
const string TableName_ColumnName = "TestName";
Dictionary and Enum:
public static string GetColumnName(ColumnId inColId)
{
[Code]....
I think I prefer the second option but it means that retrieving the column names means quite a long winded function call.
C# :: DropDownList Is Not Being Populated
Apr 11, 2014My query APPEARS to not return any results to populate my dropdown list.
public void getColumnList() {
SqlConnection con;
SqlCommand cmd;
SqlDataReader dataReader;
con = new SqlConnection(ConfigurationManager.AppSettings["ConString"]);
cmd = new SqlCommand();
[code]....
following code successfuly puts my CommandText within the DropDownList. If I copy and paste the CommandText straight into SQL server, it indeed returns the names of the columns.
dataReader.Read();
if (dataReader.HasRows) {
while (dataReader.Read()) {
chkbxlstColumn.Items.Add(cmd.CommandText);
}
}
So if my query is correct enough for SQL Server, why can't C# and ASP.NET recognize the results returned and put it into my control?
FYI I've even tried the blow (initially) and it didn't work either.
chkbxlstColumn.DataSource = dataReader;
chkbxlstColumn.DataValueField = "name";
chkbxlstColumn.DataTextField = "name";
chkbxlstColumn.DataBind();
C :: Create New Data Type Data Declared As Int
Feb 1, 2015I'm trying to create a new data type Data declared as int. What comes up to my mind is to create a structure like
Code:
typedef struct Data {
int number;
} Data;
but when I need to use the data I need to go through the structure. Is this a good way to declare a new data type?
C Sharp :: Create Xml File From Xml Stored In A DB

C Sharp :: How To Create Excel File In C#
Dec 28, 2013I am currently having issues with the following code when trying to create a excel file using C#. This is the code that I have at the moment.
oXL = new Microsoft.Office.Interop.Excel.Application();
oXL.Visible = false;
oWK = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(System.Reflection.Missing.Value));
oWK.SaveAs(path + "" + fileName);
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
oWS.Cells[1, 1] = "Student ID";
oWS.Cells[1, 2] = "Student Name";
oWK.Save();
The line that I am having issues with is
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets.get_Item(1);
If I remove it, I am able to create and save teh workbook in the directory. However, I want to make some changes on a worksheet, and that is where the issue is. I have also tried using the line of code:
oWS = (Microsoft.Office.Interop.Excel._Worksheet)oWK.Worksheets[1];
This line had no luck either. The issue I am having is the error regarding InvalidOperationException: Dynamic operations can only be performed in homogenous AppDomain.

C++ :: Create New Data Type To Store Big Integer?
Oct 17, 2014i need to create a new integer data type called BigInt to store a big big integer, which includes Dint(8 bytes) and Qint(16 bytes)
here is the hint/
typedef struct BigInt {
Int data[2];
}
How can i "scanf" and "printf" them????
void ScanBigInt(const char *format, BigInt &x)
if format is “%dd” -> input Dint, if format is “%qd”--> input Qint
void PrintBigInt(const char *format, BigInt x)
C/C++ :: How To Create Objects Of Same Data Structure (type)
Dec 31, 2014well i create a State.h class
#ifndef STATE.H
#define STATE_H
class State {
public:
virtual void handle_action() = 0;
virtual void update() = 0;
virtual void render() = 0;
};
#endif //STATE.H
What i'm trying to create is a simple State Manager for SFML! I created another class that inherits State.
#pragma once
#include "state.h"
class FirstState : public State {
public:
FirstState();
~FirstState();
void handle_action();
void update();
void render();
};
So the question is this, each state that i have will inherit the State class. However, i wanted to perhaps add each state object into a vector array. But i'm not sure as to what data type it be? I have a state manager class that will contain the vector.
What i want to do is this, each game state will create an object that will inherit functions from the state.h class. I want to store them all in a vector array, but each object is clearly named different. My curiosity was wondering, since all those different states inherit the State.h class, can i simply create a State Object std::vector<State> *states; that will contain all those different state objects?

C# :: Create Byte Array From IntPtr Without Copying Data
Apr 18, 2012let's say I have an IntPtr that points to the raw data of System.Drawing.Bitmap. is there any way to create a byte array from that IntPtr without copying the data? I'm a pretty experienced C++ programmer, so I can call ToPointer() on it and convert to a byte* to work with it as a pointer, which is no big deal for me, but using a pointer and doing pointer arithmetic increases the risk of bugs, so I'd prefer not to do it that way if there's another way.
View 4 Replies View RelatedC++ :: Create Matrix Of Data That Add Values Based On Reading Get From DVM
Apr 22, 2012Ok I'm trying to create matrix of data that I can add values to based on a reading that I will get from a DVM. I'm using a 3d vector to do this. I need to keep track of the serial number, the day and within day I need to take two readings at different temps, this will continue for 7 days.
The rows of my 3d vector will be the days, the colums will be the serial numbers the depth will be the reading at the different temps.
What I need to do is compare the first element (days) and when it is greater then or equal to 4 I will perform calculations of the readings. So all I want to do is compare the first element of the vector, How do I do this?
Here is what I got
Code:
#include <vector>
typedef std::vector<double> Double1D;
typedef std::vector<Double1D> Double2D;
typedef std::vector<Double2D> Double3D;
#define HEIGHT 5
#define WIDTH 3
