I want to log Exception in case of error on network. I have made changes in global.asax file and generated log file in it. The code works fine on localhost but when I upload the dll of global.asax file on another server and change the web config according to network credentials similar to the localhost. In case of error the method doesnot seem to work nor the file is created to write the exception. Please help
void Application_Error(object sender, EventArgs e)

It's because your application runs under NETWORK SERVICE account (by default) and don't have permissions to write in ExceptionLogFiles folder. Add user Everyone in folder properties and grant him that permission

I know you are going to tell me that this question is stupid but I really cannot find a solution to delete my file.
In fact, I open a connection to an .add file (same style as SQL in a way) but afterwards I cannot delete it because it is used by another process which is the process of my application.
While doing some research on the internet I was able to find the solution to kill the process however if I do this it stops my application. Then I also found the GC collect but it doesn't work : /
There is my code :
try
{
string idClient = "parfilux";
string tableName = "ACT,ACF";
string dataSourceDBF = "C:/winbooks/data/parfilux";
string path = dataSourceDBF ;
string pathTemp = dataSourceDBF + "/CopyTempWebService/";
if (!Directory.Exists(pathTemp)) Directory.CreateDirectory(pathTemp);
string addFile = path + "/" + idClient + ".add";
File.Copy(addFile, pathTemp + idClient.ToUpper() + ".add");
File.Copy(addFile.Replace(".add", ".ai"), pathTemp + "/" + idClient.ToUpper() + ".ai");
File.Copy(addFile.Replace(".add", ".am"), pathTemp + "/" + idClient.ToUpper() + ".am");
tableName = tableName.Replace(" ", "");
string[] tables = tableName.Split(',');
string pathTable = null;
foreach (string tab in tables)
{
pathTable = path + "/" + idClient.ToUpper() + "_" + tab.ToUpper() + ".dbf";
File.Copy(pathTable, pathTemp + idClient.ToUpper() + "_" + tab.ToUpper() + ".dbf");
File.Copy(pathTable.Replace(".dbf", ".cdx"), pathTemp + idClient.ToUpper() + "_" + tab.ToUpper() + ".cdx");
}
AdsConnection dbfCo;
//dbfCo.Close();
dbfCo = new AdsConnection(#"data Source=" + dataSourceDBF + "/CopyTempWebService/" + idClient + ".add;User ID=admin;Password=;ServerType=Local;ReadOnly=true;pooling=true;TrimTrailingSpaces=true;ShowDeleted=TRUE;TableType=CDX;LockMode=COMPATIBLE");
dbfCo.Open();
//QueryDataDBF(tableName, idClient, false);
dbfCo.Close();
dbfCo.Dispose();
//Process process = Process.GetCurrentProcess();
//Console.WriteLine(process.MainModule);
//process.Kill();
//foreach(Process pro in process)
//{
// Console.WriteLine(pro);
// if(pro.ProcessName == pathTemp + idClient.ToUpper() + ".add")
// {
// pro.Kill();
// }
//}
//System.GC.Collect();
//System.GC.WaitForPendingFinalizers();
//File.Delete(pathTemp + idClient.ToUpper() + ".add");
Directory.Delete(dataSourceDBF + "/CopyTempWebService", true);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
I open a connection to my .add with the Advantage Data Provider library.
Do you have any idea to fix this problem ? thank you in advance ;)
In a WinForms project I am trying to extract archive in destination folder, but I not want to extract the folder from archive in destination folder.
I want to extract only the file.
My code:
private void button1_Click(object sender, EventArgs e)
{
string Info = "";
string extractPath = #"D:\dosfiles\SYNOPD\SYNOPD$$.PD\" + comboBox3.SelectedItem.ToString() + #"\" + comboBox2.SelectedItem.ToString() + #"\";
string zipPath = #"D:\dosfiles\" + comboBox1.SelectedItem.ToString() + "_" + comboBox2.SelectedItem.ToString() + "_" + comboBox3.SelectedItem.ToString() + "S" + ".zip";
if (!Directory.Exists(extractPath))
{
Info += "Folder not exists in D:\\dosfiles\\SYNOPD\\SYNOPD$$.PD\\" + comboBox3.SelectedItem.ToString() + #"\" + comboBox2.SelectedItem.ToString() + #"\" + comboBox1.SelectedItem.ToString();
}
else if(Directory.Exists(extractPath))
{
if (Directory.Exists(extractPath))
{
Directory.Delete(extractPath, true);
}
ZipFile.ExtractToDirectory(zipPath, extractPath);
Info += "Your synoptic files has been extracted in D:\\dosfiles\\SYNOPD\\SYNOPD$$.PD\\" + comboBox3.SelectedItem.ToString() + #"\" + comboBox2.SelectedItem.ToString() + #"\" + comboBox1.SelectedItem.ToString() + Environment.NewLine;
}
if (Info != "")
{
MessageBox.Show(Info);
Application.Exit();
}
}
}
}
The process cannot access the file 'file path' because it is being used by another process.
i have found these 2 question
File being used by another process after using File.Create()
and
Does File.AppendAllText close the file after the operation
this is an API that i have and need to save every request that comes in and the result that goes out,
there might be more than one request that a give time
my code
public static void SaveTheRequestAndResponse(string type, SearchRequest searchRequest = null, dynamic result = null)
{
var FilePath = AppDomain.CurrentDomain.BaseDirectory + #"SearchRequest";
bool exists = Directory.Exists(FilePath);
if (!exists)
{
var stream = Directory.CreateDirectory(FilePath);
}
if (type == "request")
{
string Space = ", ";
StringBuilder request = new StringBuilder();
request.Append("Search Id : " + searchRequest.ID);
request.Append(Space + "Company Name : " + searchRequest.CompanyName);
request.Append(Space + "Country Code : " + searchRequest.CountryCode);
request.Append(Space + "Search Type : " + searchRequest.SeacrhType);
request.Append(Space + "Request Time : " + DateTime.Now + Environment.NewLine);
var DataToBeSave = request.ToString();
System.IO.File.AppendAllText(FilePath + #"\" + "FileNAme" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt", DataToBeSave + Environment.NewLine);
}
else
{
string Space = ", ";
StringBuilder SearchResult = new StringBuilder();
SearchResult.Append("The result for Request" + Space);
SearchResult.Append("Search Id : " + searchRequest.ID + Space);
SearchResult.Append("States Code : " + result.StatusCode + Space);
SearchResult.Append("Result Time : " + DateTime.Now + Environment.NewLine);
var DataToBeSave = SearchResult.ToString();
System.IO.File.AppendAllText(FilePath + #"\" + "FileNAme" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt", DataToBeSave + Environment.NewLine);
}
}
my understanding is that the File.AppendAllText will close after the Operation so why do i get the this error
my code is having an race condition, and this is because the API is being call by more than one user at each given time, even that
System.IO.File.AppendAllText(FilePath + #"\" + "FileNAme" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt", DataToBeSave + Environment.NewLine);
will close after the Operation, it still need time do its work and only one connection can be open at each give time so the thread need to be lock and that can be done by
private static Object thisLock = new Object();
lock (thisLock)
{
System.IO.File.AppendAllText(FilePath + #"\" + "DandB" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt", DataToBeSave + Environment.NewLine);
}

I'm having issues with a C# Winforms file IO. The code complies just fine, but then it returns errors on execution.
The output code is here:
private void saveData()
{
string fullPath = System.Environment.GetEnvironmentVariable(#"%MyDocuments%\HellsingRPG\");
StreamWriter writer = new StreamWriter(fullPath + textBox2.Text + ".txt");
writer.WriteLine(textBox1.Text + "," + textBox2.Text + "," + textBox3.Text + "," + textBox4.Text + "," + comboBox1.SelectedText + "," +
numericUpDown25.Value + "," + numericUpDown1.Value + "," + numericUpDown2.Value + "," + numericUpDown3.Value + "," + numericUpDown4.Value + "," +
numericUpDown5.Value + "," + numericUpDown6.Value + "," + numericUpDown7.Value + "," + numericUpDown8.Value + "," + numericUpDown9.Value + "," +
numericUpDown10.Value + "," + numericUpDown11.Value + "," + numericUpDown12.Value + "," + numericUpDown13.Value + "," + numericUpDown14.Value
+ "," + numericUpDown15.Value + "," + numericUpDown16.Value + "," + numericUpDown17.Value + "," + numericUpDown18.Value + "," +
numericUpDown19.Value + "," + numericUpDown20.Value + "," + numericUpDown21.Value + "," + numericUpDown22.Value);
writer.Close();
}
And the code to load the data is here:
private void loadData()
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = System.Environment.GetEnvironmentVariable(#"%MyDocuments%\HellsingRPG\");
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog1.FilterIndex = 2;
openFileDialog1.RestoreDirectory = true;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = openFileDialog1.OpenFile()) != null)
{
using (myStream)
{
List<string> myData = parseCSV(System.Convert.ToString(myStream));
textBox1.Text = myData[0];
textBox2.Text = myData[1];
textBox3.Text = myData[3];
textBox4.Text = myData[4];
comboBox1.SelectedText = myData[5];
numericUpDown25.Value = System.Convert.ToDecimal(myData[6]);
numericUpDown1.Value = System.Convert.ToDecimal(myData[7]);
numericUpDown2.Value = System.Convert.ToDecimal(myData[8]);
numericUpDown3.Value = System.Convert.ToDecimal(myData[9]);
numericUpDown4.Value = System.Convert.ToDecimal(myData[10]);
numericUpDown5.Value = System.Convert.ToDecimal(myData[11]);
numericUpDown6.Value = System.Convert.ToDecimal(myData[12]);
numericUpDown7.Value = System.Convert.ToDecimal(myData[13]);
numericUpDown8.Value = System.Convert.ToDecimal(myData[14]);
numericUpDown9.Value = System.Convert.ToDecimal(myData[15]);
numericUpDown10.Value = System.Convert.ToDecimal(myData[16]);
numericUpDown11.Value = System.Convert.ToDecimal(myData[17]);
numericUpDown12.Value = System.Convert.ToDecimal(myData[18]);
numericUpDown13.Value = System.Convert.ToDecimal(myData[19]);
numericUpDown14.Value = System.Convert.ToDecimal(myData[20]);
numericUpDown15.Value = System.Convert.ToDecimal(myData[21]);
numericUpDown16.Value = System.Convert.ToDecimal(myData[22]);
numericUpDown17.Value = System.Convert.ToDecimal(myData[23]);
numericUpDown18.Value = System.Convert.ToDecimal(myData[24]);
numericUpDown19.Value = System.Convert.ToDecimal(myData[25]);
numericUpDown20.Value = System.Convert.ToDecimal(myData[26]);
numericUpDown21.Value = System.Convert.ToDecimal(myData[27]);
numericUpDown22.Value = System.Convert.ToDecimal(myData[28]);
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
}
And that compiles just fine. But when I use it, I get the following errors:
"Could not find file "C:\Users\collmark\Documents\Visual Studio
2015\Projects\WindowsFormsApplication1\WindowsFormsApplication1\bin\Release\System.IO.Filestream".
"Error: Could not read file from disk. Original error: Index out of
range. Must be non-negative and less than the size of the collection.
Parameter name: index."
Thanks
your save data seems to save 22 fields while the read expects 28.
I suspect the myData object does not contain the fields index you are trying to read, hence index out of range.
do yourself a favour when printing exception data don't limit yourself to the message but print the whole stack trace, it will tell you which line is faulty giving you a hint at the actual problem.
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.ToString());
I have the following bits of code:
public static void WriteHTML(string cFile, List<Movie> mList)
{
int lineID = 0;
string strMovie, strGenre, tmpGenre = null;
// initiates streamwriter for catalog output file
FileStream fs = new FileStream(cFile, FileMode.Create);

catalog.WriteLine(strHeader);
foreach (Movie m in mList)
{

catalog.WriteLine(strMovie);

public static void WritePDF(string cFile, string pdfFile)
{
// Sets up PDF to write to
EO.Pdf.HtmlToPdf.Options.PageSize = new SizeF(8.5f, 11f);
EO.Pdf.HtmlToPdf.Options.OutputArea = new RectangleF(0.5f, .25f, 7.5f, 10.25f);
HtmlToPdf.ConvertUrl(cFile, pdfFile);
}
My HTML file writes fine, but when it tried to convert the HTML file to PDF I get an exception that it times out.
I did a test previously, and had it convert the code (not the file) within the WriteHTML function and it worked great. I have confirmed that the cFile exists and is a valid file (created previously in WriteHTML). The path to pdfFile is valid, and the documentation does not state the file needs to already exist (.ConvertHTML did not need an existing file).
Only thing I can think of is that the catalog.html file isn't released and ready to read yet. I made sure I closed it in the WriteHTML function. How can I test that the file is ready to be read?
Tried setting .MaxLoadWaitTime = 120000 with no luck.
Any clues would be greatly appreciated!
After a battery of further testing, and scouring the EO support forums, it appears to be a limitation of the free version of EO. It seems to have difficulty with HTML files over 3MB.
It's a shame since the EO product is very good, but not unfortunately not worth $250 IMO.
