c# windows form System.Runtime.InteropServices.COMException - c#

I am trying to write c # code that automates the process of filling out Word templates. I use DataGridView because I don't know how many types of elements I need to replace. Upon completion of work, it throws an error System.Runtime.InteropServices.COMException: "The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)" thanks

Your solution needs to have the word installed to work, you could use OpenXML instead.
But considering you want to keep this dependency on Word, check if the Remote Procedure Call is started and running on your windows services

Can anyone help me how import data from txt file without several columns??
thx for all answer.
I have gone through your code and also the error you are facing and came to know that your text file while taken in account also have null spaces or multiple blank space and when you are split it on whitespace base it will also have some null values. I have updated your code for the same please try it and in case you face some problem please feel free to ask me.
Here is the 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.Windows.Forms;
namespace WindowsFormsApplication10
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
System.IO.StreamReader file = new System.IO.StreamReader("C:\\Users\\terrazo\\Desktop\\test1.txt");
string[] columnnames = file.ReadLine().Split(' ');
DataTable dt = new DataTable();
foreach (string c in columnnames)
{
if (c != "")
{
dt.Columns.Add(c);
}
}
string newline;
while ((newline = file.ReadLine()) != null)
{
DataRow dr = dt.NewRow();
string[] values = newline.Split(' ');
for (int i = 0; i < values.Length; i++)
{
if (values[i] != "")
{
dr[i] = values[i];
}
}
dt.Rows.Add(dr);
}
file.Close();
dataGridView1.DataSource = dt;
}
}
}

How can i get the listening start time with speechRecognition in c#

I'm doing project in C# that read from a video file and convert it to subtitle text, but i want to get the start time for each text line so it can be shown in the video at the right time, i tried the AudioPosition but it not working well, is there a away to do this?
using System;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Speech.Recognition;
using System.Threading.Tasks;
namespace project
{
public partial class Form1 : Form
{
StringBuilder sb = new StringBuilder();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
string[] tokens;
private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.Filter = "WAV|*.wav";
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
}
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
Grammar gr = new DictationGrammar();
sre.LoadGrammar(gr);
sre.SetInputToWaveFile(#openFileDialog1.FileName);
while (true)
{
try
{
var recText = sre.Recognize();
sb.Append(recText.Audio.AudioPosition + " * ");
textBox4.Text = sb.ToString();
tokens = sb.ToString().Split('#');
for (int i = 0; i < tokens.Length - 1; i++)
{
textBox2.AppendText(tokens.Length.ToString());
textBox2.AppendText(i+" - "+tokens[i]);
textBox2.AppendText(Environment.NewLine);
}
}
catch (Exception ex)
{
break;
}
}
}

How can i save settings of my app to a text file and read them back on load?

Read them back in app constructor and also maybe in other places in program.
I have a new form i created with some checkboxes:
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;
namespace Options
{
public partial class OptionsMenuForm : Form
{
public OptionsMenuForm()
{
InitializeComponent();
}
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
if (checkBox1.Checked)
{
Settings.downloadonstart = true;
}
else
{
Settings.downloadonstart = false;
}
}
private void checkBox2_CheckedChanged(object sender, EventArgs e)
{
if (checkBox2.Checked)
{
Settings.loadonstart = true;
}
else
{
Settings.loadonstart = false;
}
}
private void checkBox3_CheckedChanged(object sender, EventArgs e)
{
if (checkBox3.Checked)
{
Settings.startminimized = true;
}
else
{
Settings.startminimized = false;
}
}
private void checkBox4_CheckedChanged(object sender, EventArgs e)
{
if (checkBox4.Checked)
{
Settings.displaynotifications = true;
}
else
{
Settings.displaynotifications = false;
}
}
}
}
Now i want to save each time the state of one/any of the checkboxes.
I also added a class i'm using th pass the variables between the new form and form1:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Options
{
class Settings
{
public static bool downloadonstart;
public static bool loadonstart;
public static bool startminimized;
public static bool displaynotifications;
}
}
Now how can i use this in form1 by saving the settings to a text file ?
For example in the text file the content will be something like:
CheckBox1 = true
CheckBox2 = false
CheckBox3 = false
CheckBox4 = true
And then if i change the state of one of them it will write it in the text file:
CheckBox1 = false
CheckBox2 = false
CheckBox3 = true
CheckBox4 = true
In form1 top i added
string settingsFile = "settings.txt";
string settingsFileDirectory = "\\settings";
StreamWriter writetosettingsfile;
Then in constructor
settingsFileDirectory = Path.GetDirectoryName(Application.LocalUserAppDataPath) +
settingsFileDirectory;
if (!Directory.Exists(settingsFileDirectory))
{
Directory.CreateDirectory(settingsFileDirectory);
}
I know the app it self have a settings in the properties but i wanted to use a text file this time since i have many settings and i might have more later.
Or using the settings in the app in properties i did:
But now how do i use with it in my program to save every checkbox state in the new form and then using it in form1 ?
You can use json.net
Something like this to save the data
private void Form1_Load(object sender, EventArgs e)
{
checkBox1.CheckedChanged += checkBox_CheckedChanged;
checkBox2.CheckedChanged += checkBox_CheckedChanged;
checkBox3.CheckedChanged += checkBox_CheckedChanged;
checkBox4.CheckedChanged += checkBox_CheckedChanged;
}
private void checkBox_CheckedChanged(object sender, EventArgs e)
{
var settings = new Settings();
settings.downloadonstart = checkBox1.Checked;
settings.loadonstart = checkBox2.Checked;
settings.startminimized = checkBox3.Checked;
settings.displaynotifications = checkBox4.Checked;
File.WriteAllText(#"c:\configfile.json", JsonConvert.SerializeObject(settings));
}
You can read the file like this
Settings settings = JsonConvert.DeserializeObject<Settings>(File.ReadAllText(#"c:\configfile.json"));
Documentation:
http://www.newtonsoft.com/json/help/html/Introduction.htm
public OptionsMenuForm()
{
InitializeComponent();
//Read the settings from a file with comma delimited 1's and 0's or whatever you like
string[] values = System.IO.File.ReadAllText("c:\temp\a.txt").Split(',');
checkBox1.Checked = Convert.ToBoolean(Convert.ToInt32(values[0]));
checkBox2.Checked = Convert.ToBoolean(Convert.ToInt32(values[1]));;
//On checkbox changes save the settings
checkBox1.CheckedChanged +=SaveSettings;
checkBox2.CheckedChanged +=SaveSettings;
}
public void SaveSettings(object sender,EventArgs e)
{
StringBuilder sbValues = new StringBuilder();
int i = 0;
i = checkBox1.Checked ? 1 : 0;
sbValues.Append(i.ToString() + ",");
i = checkBox2.Checked ? 1 : 0;
sbValues.Append(i.ToString() + ",");
System.IO.File.WriteAllText("c:\temp\a.txt",sbValues.ToString());
}
It is recommended that you use XML when using the .NET framework.
public static void ConvertStringToXmlList()
{
XElement xml = new XElement
(
"Items",
(
from x in [YourList] select new XElement("Item", x)
)
);
XDocument doc = new XDocument
(
xml
);
doc.Save(Environment.CurrentDirectory + "/settings.xml");
}
var xmlReader = new XmlTextReader("settings.xml");
while (xmlReader.Read())
{
switch (reader.NodeType)
{
case [nodetype]:
// Code here
break;
}
}
Also, instead of creating the same event for all four checkbox's, just use 1.
Inside of the single event put:
ckCheckBox1.Checked = !ckCheckBox1.Checked;

C# form instantly closing

All of a sudden my form window has begun to close as soon as the application is launched. There's nothing in the output window that gives a hint as to what could be causing it and there are no errors thrown at me either. Does anybody have any ideas?
I've provided to form's class.
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;
namespace ProjectBoardManagement {
public partial class CreateBoard : Form {
Functions funcs = new Functions();
public CreateBoard() {
InitializeComponent();
}
private void CreateBoardButton_Click(object sender, EventArgs e) {
String BoardName = BoardNameText.Text;
String Pages = "";
String Labels = "";
foreach (ListViewItem i in PageNameList.Items) {
Pages = (Pages + i.Name.ToString() + ",");
}
foreach (ListViewItem i in LabelNameList.Items) {
Labels = (Labels + i.Name.ToString() + ",");
}
String BoardFile = ("board_" + BoardName + ".txt");
funcs.SaveSetting(BoardFile, "name", BoardName);
funcs.SaveSetting(BoardFile, "pages", Pages);
funcs.SaveSetting(BoardFile, "labels", Labels);
FormManagement.CreateBoard.Hide();
FormManagement.BoardList.LoadBoardList();
}
private void PageNameButtonAdd_Click(object sender, EventArgs e) {
String pagename = PageNameText.Text;
if (pagename != "") {
PageNameList.Items.Add(pagename);
}
PageNameText.Text = "";
}
private void LabelNameButtonAdd_Click(object sender, EventArgs e) {
String labelname = LabelNameText.Text;
if (labelname != "") {
LabelNameList.Items.Add(labelname);
}
LabelNameText.Text = "";
}
}
}
Obvious first thing to do - run it in Debug mode and stop execution on all exceptions. This should give you enough information on how to go from there.
Otherwise Functions funcs = new Functions(); looks suspicious.
