I use this service to translate English word:
http://services.aonaware.com/DictService/DictService.asmx?op=Define
I add this link to my windows Form application by click right on References -> Add Service Reference -> and best the URL of service in Address field.
then I write this code:
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 هجوم_الكسر_الأعمى.ServiceReference1;
namespace هجوم_الكسر_الأعمى
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//Definition a = new Definition();
WordDefinition sv = new WordDefinition();
sv.Word="Go";
string b= sv.Word;
textBox1.Text = b; ;
}
}
}
The problem is that I don't have the result, I have the same world witch I write it "Go"?
You're not doing anything here, you're just creating an instance of WordDefinition locally that you set to the word you're trying to search for.
You need to invoke the service call, for example..
using (var dictionaryService = new ServiceReference1.DictServiceSoapClient("DictServiceSoap"))
{
var definition = dictionaryService.Define("Programming");
Console.WriteLine(definition.Definitions.First().WordDefinition);
}
I am not sure if I understand you, but if you would like to have result from sv.Word method I think you shloud try to check if there is some method with Result, for example: sv.WordResult and it will add event handler to this.

I am trying to load Google and get the ID of the searchbox. The ID of the box is "lst-ib". Which when the program goes to debug it is expecting a semicolon.
Is there a way around it to get the element id? So far I have:
using System;
using System.Diagnostics;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace ConsoleApplication1
{
class Program
{
public void Main(string[] args)
{
Process.Start("www.google.com");
HtmlElement lst-ib = WebBrowser1.Document.All["foo"];
//expects a semi colon on the line above after the element id
if (lst-ib != null)
{
lst-ib.InnerText = "test";
}
Console.ReadKey();
}
}
}
That is C# code and - is not valid in identifiers. Feel free to name the variable as you wish – it has no bearing on what the ID of the element is.
The - is an operator, you cannot use this way!
Here you will find more information about operators:
https://msdn.microsoft.com/en-us/library/6a71f45d.aspx
I recomend you rename - (trace) to _ (underline) or anyway you want

I'm attempting to grab a device handle on the Synaptics Touchpad using the Synaptics SDK, specifically using methods in the SYNCTRLLib.
However, the SYNCTRL method failed to find it, returning -1.
Syn.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SYNCOMLib;
using SYNCTRLLib;
namespace TP_Test1
{
class Syn
{
SynAPICtrl SynTP_API = new SynAPICtrl();
SynDeviceCtrl SynTP_Dev = new SynDeviceCtrl();
SynPacketCtrl SynTP_Pack = new SynPacketCtrl();
int DeviceHandle;
//Constructor
public Syn ()
{
SynTP_API.Initialize();
SynTP_API.Activate();
//DeviceHandle == -1 ? Can't find device?
DeviceHandle = SynTP_API.FindDevice(new SynConnectionType(), new SynDeviceType(), 0);
//Below line causing Unhandled Exception
SynTP_Dev.Select(DeviceHandle);
SynTP_Dev.Activate();
SynTP_Dev.OnPacket += SynTP_Dev_OnPacket;
}
public void SynTP_Dev_OnPacket()
{
Console.WriteLine(SynTP_Pack.FingerState);
Console.WriteLine(SynTP_Pack.X);
Console.WriteLine(SynTP_Pack.Y);
}
}
}
Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using SYNCOMLib;
using SYNCTRLLib;
namespace TP_Test1
{
class Program
{
static void Main(string[] args)
{
Syn mySyn = new Syn();
mySyn.SynTP_Dev_OnPacket();
}
}
}
I see that you are using the C# wrappers for Synaptics SDK. Even though CPP code might be not trivial to you, you might want to take a look at the file Samples/ComTest.cpp. It contains some example logic in order to find devices, more specifically at lines 66-76:
// Find a device, preferentially a TouchPad or Styk.
ISynDevice *pDevice = 0;
long lHandle = -1;
if ((pAPI->FindDevice(SE_ConnectionAny, SE_DeviceTouchPad, &lHandle) &&
pAPI->FindDevice(SE_ConnectionAny, SE_DeviceStyk, &lHandle) &&
pAPI->FindDevice(SE_ConnectionAny, SE_DeviceAny, &lHandle)) ||
pAPI->CreateDevice(lHandle, &pDevice))
{
printf("Unable to find a Synaptics Device.\n");
exit(-1);
}
Also, make sure you have registered the dlls. According to the ReadSynSDK.txt file:
For certain purposes it may be necessary to register the dlls
that are provided with the SDK. This can be done with the windows regsvr32
utility.
I have to make a program to back up my IDM download list every day, because there is other ones using my computer and they removing my download list.
IDM API only lets me add download to IDM list, so is there any library or other way to back up my IDM download list using C#?
thanks for helping
Thanks to #Setsu found out a solution. there is a key in registry which contains all of the URLs. the key is HKEY_CURRENT_USER\Software\DownloadManager and it contains keys which contains values named Url0 with the URL in it.
As an example HKEY_CURRENT_USER\Software\DownloadManager\85\Url0 contains one of added link to IDM download list.
So I searched all of the HKEY_CURRENT_USER\Software\DownloadManager subkeys for Url0 and saved the values to a list box using this code:
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 Microsoft.Win32;
namespace IDMListSaver
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
RegistryKey key = Registry.CurrentUser.OpenSubKey("Software\\DownloadManager");
string[] keys = key.GetSubKeyNames();
for (int i = 0; i <= key.SubKeyCount-1; i++)
{
key = key.OpenSubKey(keys[i]);
Object o = key.GetValue("Url0");
if (o != null)
{
listBox1.Items.Add(o);
}
key = Registry.CurrentUser.OpenSubKey("Software\\DownloadManager");
}
}
}
}
It definitely can get better, but it solved my problem until here.
So thanks again #Setsu
I'm a beginner in c#, currently attempting a windows form project. I've designed a form titled drugform. I use the dataset method to connect to the database. Here is my code:
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.Data.SqlClient;
using System.Windows.Forms;
using drugstoreform.BaseInfoTableAdapters;
namespace drugstoreform
{
public partial class DrugForm : Form
{
int Row = -1;
public DrugForm()
{
InitializeComponent();
}
private void Register_click(object sender, EventArgs e)
{
try
{
dbm_Medecine db = new dbm_Medecine();
db.Insert(Convert.ToInt32(DrugCode.Text.Trim()), DrugName.Text.Trim(), Convert.ToString(HowUse.Text.Trim()), Convert.ToDecimal(price.Text.Trim()));
}
catch(SqlException ex)
{
}
When I click on the register button, I get this error: input string was not in a correct format.
You get the error inConvert.ToInt32 and/or Convert.ToDecimal because the input was invalid. You can use int.TryParse and decimal.TryParse to validate it:
int drugCode;
decimal price;
if (int.TryParse(DrugCode.Text.Trim(), out drugCode) && decimal.TryParse(price.Text.Trim(), out price))
{
db.Insert(drugCode, DrugName.Text.Trim(), HowUse.Text.Trim(), price);
}
In the if drugCode and price are initialized with the correct value. Otherwise you should provide an error message that the user should provide correct input.
Possible reasons: perhaps the user enters 2.6 but the computer uses , as decimal separator. Or DrugCode.Text or price.Text are simply empty.
i know i could search proccessId / name of running tasks and kill processes i need .
though till now i was not developing schedualed tasks / self executble Applications,
so i didn't need to know how to make the application close itself after execition
trying to close everything (including WebDriver) via Application.Exit + OR this.Close()
right after i have got what i was looking for. mission Complete .
please close ... no more work for you .
but mr . Program.cs still needs somthing from Form1.
saying somthing about
Cannot access a disposed object.
Object name: 'Form1'.
any combination of both was returning in some point an exeption error
(from program.cs ) even though mission complete . no more code was requested .(?) by me..atleast.

Why use a winform application? A Console application would probably suffice for what you are doing. Once Main() ends your app will close as well. Main() never ends in a winform app because of the applications runloop.
Edit:
Here would be the correct way to do this. You need to register to the forms Load event and run your code there, not in the constructor. You can't close a winform from inside a constructor.
Edit 2: Put this code in the Form1() constructor. Somewhere after InitializeComponent();
this.Load += (sender,args)=>{ /*do all your work here*/
string extractededVal = Iengn.ExtractPageValue(Iengn.itrfWebEng);
string flnm = #" the directory path to file --> \dolarRate.asp";
File.WriteAllText(fn, extractededVal);
Application.Exit();
};
