You should get a decent idea of what needs to be done, here[^]. Look at the first answer to get an idea on how to do this without leaving your code vulnerable to SQL Injection Attacks.

Hi,

I want to fetch data from SQL database, and display the same on my HTML page in table format using Angular JS.

I am able to get the data in the scope variable, but it is not getting displayed in the HTML page.

Please check the code that I have written below, and help me fixing the issue.

Thanks in advance.

HTML code:

This is not a C# issue. Please use the ASP.NET or Javascript forum, as appropriate.

So I'm using this command to open a picture in C sharp

Process.Start(@"C:\MyPicture.jpg");

Is there anyway I can open the latest picture in the folder?

Re: Picture Viewer.

Pete O'Hanlon26-Jul-15 23:18

Yes. You could iterate over all the picture files in the directory, looking at the file attributes for the files. That should help you find the latest.

var directory = new DirectoryInfo(@"C:\");

var latest = (from f in directory.EnumerateFiles("*.jpg")
              orderby f.CreationTime
              select f.FullName).LastOrDefault();

Console.WriteLine(latest);

Returns null in case there are no jpg files found.

I am trying to complete a standalone *.exe file that will simply allow read and write FirstSlideNumber property in a PowerPower 2013 pptx file, without opening PowerPoint. (VS 2015).

My application can find the file name etc. but as I am new to C# after returning to programming after 10 years, I need a code fragment example in C#

https://msdn.microsoft.com/EN-US/library/office/ff744279.aspx is VBA is no help.

This is my code fragment:

using System;
using System.IO;
using System.Windows.Forms;
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Presentation;
using Microsoft.Office.Interop.PowerPoint;
using Powerpoint = Microsoft.Office.Interop.PowerPoint;
…

//file Open file
using (PresentationDocument mypptx = PresentationDocument.Open(myFileName, true))
{
Int iFirstSlideNumber = PageStepup?? //PageStepup. Only allows “Equals” or “ReferenceEquals”
}

Re: C# Read/Write PowerPoint.PageSetup.FirstSlideNumber

Richard Deeming27-Jul-15 2:02

Something like this should work:

using (PresentationDocument mypptx = PresentationDocument.Open(myFileName, true))
{
    int firstSlideNumber = mypptx.PresentationPart.Presentation.FirstSlideNum;
    mypptx.PresentationPart.Presentation.FirstSlideNum = 42;
}

PresentationDocument Class[^]
PresentationDocument.PresentationPart Property[^]
PresentationPart.Presentation Property[^]
Presentation.FirstSlideNum Property[^]

Most likely because you did not declare the variable @id. But that is just a guess since you decided not to share the code that is causing the error.

Your SQL-statement contains a parameter named @id which you didn't supply to the command object. Most probably.

How to copy and replace folder in desktop with C#/Winforms?

George Tourtsinakis26-Jul-15 7:40

Re: How to copy and replace folder in desktop with C#/Winforms?

26-Jul-15 7:40

Hi guys,
I want when i have a radio button checked by pressing a button the desired folder with all files in it to be in desktop and replacing anything.

I have this :

public partial class Form1 : Form
    {


        string desktop = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

and then :

private void button1_Click(object sender, EventArgs e)
        {


            foreach (string file in Directory.GetFiles(SourceOneToCopyBox.Text))
            {
                File.Copy(file, Path.Combine(OutputDirectory1.Text, Path.GetFileName(file)), true);
                if (YesRadioButton.Checked == true)
                {
                    File.Copy(file, Path.Combine(desktop, Path.GetFileName(file)), true);

                }

            }
        }

Thank you in advance.While the code works for every directory everywhere I can't do anything with the directory I want in desktop.

Let's say I have a directory c:\test with some files in it.I want this directory to be copied in desktop with every file in it.If it exists I want to replace it with the new files .I m making a program so I can have backup of my projects easily and not copying pasting with windows clicks all the time .

This is the whole code which creates a folder in desktop Downloads\Downloads and also some files are copies to desktop\Downloads and some others to desktop\Downloads\Downloads.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;//We need this namespace to be used so we can have the file class
//that gives us the ability to copy,delte files etc.

namespace EasyCopyFiles
{
    public partial class Form1 : Form
    {


        string desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);


        public Form1()
        {
            InitializeComponent();



        }

        private void button1_Click(object sender, EventArgs e)
        {


            foreach (string file in Directory.GetFiles(SourceOneToCopyBox.Text))//SourceOneToCopy
                //textbox we read from user input exammple c:\test
            {
                //OutputDirectory1 also a text box we read from user example d:\test
                File.Copy(file, Path.Combine(OutputDirectory1.Text, Path.GetFileName(file)), true);

                if (YesRadioButton.Checked == true)
                {
                    desktop += "\\Downloads";//With the \\ we create the path we want
                    if (!System.IO.Directory.Exists(desktop))
                    {

                        DirectoryInfo directory = Directory.CreateDirectory(desktop);

                    }

                    File.Copy(file, Path.Combine(desktop, Path.GetFileName(file)), true);


                }

            }
        }

    }
}

Thank you again I m so close to it.Thank you a lot.

George Tourtsinakis27-Jul-15 1:18

Re: How to copy and replace folder in desktop with C#/Winforms?

27-Jul-15 1:18

The problem is that either I can create a new empty folder or if the folder already exists it replaces the files .If the folder doesn't exist I get an error a bug or something which crashes.

Well, since we cannot see your screen, we cannot guess which, or what any of them might say. Please provide all the information relating to your problem, including the full details of the error, and the point in your code where it occurs.

Re: How to copy and replace folder in desktop with C#/Winforms?

System.IO.DirectoryNotFoundException

{"Could not find a part of the path 'd:\\test\\130123094607-kevin-durant-dunk-lamar-odom-012313.1200x672.jpg'."}

This happens when we have for example to copy c:\test to d:\test and the d:\ doesn't have the folder.If I create the folder manually the error disappears but the thing is I want the folder to be created if it doesn't exist and if it does exist to overwrite every file in it.
Thank you again for your time.
