I have an ASP.NET application on my local machine that works. This application takes an SVG file and creates a PNG from it using inkscape. I have tried to migrate that application to my production server. Oddly, the png creation is not working. The really strange part is, an Exception is not being thrown either. I have taken the command line parameters that are being created and copied and pasted them into the command line environment and they work. For instance, here is the line:
inkscape.exe -f "C:\inetpub\wwwroot\MyTest\sample.svg" -e "C:\inetpub\wwwroot\MyTest\sample.png"
I thought it was something simple, so I extracted the code into a sample web project. This project just converts a .svg to a .png. Once again, it worked in my local environment, but not in the production environment. Here is the code:
protected void executeButton_Click(object sender, EventArgs e)
{
try
{
string sourceFile = Server.MapPath("svg") + "\\" + ConfigurationManager.AppSettings["sourceFile"];
string targetFile = Server.MapPath("png") + "\\" + ConfigurationManager.AppSettings["targetFile"];
string args = "-f \"" + sourceFile + "\" -e \"" + targetFile + "\" -w100 -h40";
string inkscape = ConfigurationManager.AppSettings["inkscapeExe"];
// Generate the png via inkscape
ProcessStartInfo inkscapeInfo = new ProcessStartInfo(inkscape, args);
Process inkscape = Process.Start(inkscapeInfo);
inkscape.WaitForExit(5000);
runLiteral.Text = "Success!<br />" + args;
}
catch (Exception ex)
{
runLiteral.Text = ex.GetType().FullName + "<br />" + ex.Message + "<br />" + ex.StackTrace;
}
}
Can someone tell me what I'm doing wrong?
Thank you!
A couple things to check:
Make sure that the application pool identity for the web application (found in IIS, usually NetworkService) has permissions to execute inkscape.exe
If that is fine, check to make sure that the directory grants Modify permissions to the apppool identity on the directory(ies) you are writing the PNG to ("C:\inetpub\wwwroot\MyTest")
Alternatively, you can use impersonation to run the executable under a specific Windows account.

I'm trying to create a function for an application to automatically copy over specific files during the final stage of a job. The only issue here is that the copy location is a protected share drive and uses a separate login instead of being validated by the active directory so I've got to do a bit of a workaround to get File.Copy() working. My workaround has been to call the built in net.exe utility and passing a command line argument that points to the share drive to open up a connection to the drive then using File.Copy() to get the file where it needs to go then deleting the connection. The issue at hand is that this works great on my computer but when anyone else on the team runs the same program a "Logon failure: unknown user name or bad password" is thrown. I'm at a bit of loss as to why this would happen since the username and password are static and not being changed and everyone on the team has the same network permissions I do. Here is the WPF/C# code I'm using to do this:
try
{
string mrdfDropPath = #"dropPathHere";
string MRDFPath = #"storePath\test.xml";
string command = #"use " + mrdfDropPath + #" /user:CORP\Username Password";
Process.Start("net.exe", command);
File.Copy(MRDFPath, mrdfDropPath + "test.xml");
string command2 = #"use " + mrdfDropPath + #" /delete";
Process.Start("net.exe", command2);
StreamWriter writer = new StreamWriter(#"logPath\log.txt", true);
writer.WriteLine(mrdfDropPath + "test.xml" + "," + File.GetLastWriteTime(MRDFPath).ToString());
writer.Close();
}
catch (Exception e)
{
StreamWriter writer = new StreamWriter(#"logPath\log.txt", true);
writer.WriteLine(e.Message);
writer.Close();
}
Like I said this works as expected during debug and when I run the application, but for anyone else it is throwing the error.
I'm having problems when copying a .txt from a local server ("D:\AuditFiles") to a shared folder in another server ("\\PrintServer\SharedFolder"). It throws the exception:
"The filename, directory name, or volume label syntax is incorrect."
I thought it could be something with the path format, so I tried by adding to the server path an #:
#Configuration.Manager["Path"] | #"\\ServerPath\SharedFolder"
I've also tried with this format: \\ServerPath\SharedFolder... None of them worked.
By the way its not an access problem, cause i've tried to do the same thing running a command prompt from within c#:
System.Diagnostics.Process.Start("cmd.exe", "/C COPY PATH1, PATH2"); //This worked and copied the file.
I'd be greatful if someone could give me a clue of what could be the problem here. At least an advice of what to do.
Thanks in advance and sorry me bad english!
Edit:
This is the part of the code that should work:
string pathPrevDay = "D:\AuditFiles\enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";
if(File.Exists(pathPrevDay))
{
File.Copy(pathPrevDay, #ConfigurationManager.AppSettings["MAIL_SERVER_PATH"]);
}
You need to escape the backslashes and indicate the name of the file in File.Copy(pathPrevDay, ConfigurationManager.AppSettings["MAIL_SERVER_PATH"]);.
Change this:
string pathPrevDay = "D:\AuditFiles\enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";
to this:
string pathPrevDay = "D:\\AuditFiles\\enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";
You can also use single slashes (/) instead like this:
string pathPrevDay = "D:/AuditFiles/enc_" + svr.Name + "_counts" + day.AddDays(-1).ToString("dd-MM-yy") + ".txt";
I am trying to copy a file generated (Excel file) by my c# code into a remote network path to which I have access as below:
string folder = "\\\\testing-path\\Audit\\Reports";
if (!(Directory.Exists(folder + "\\" + DateTime.Now.ToString("MM-dd-yyyy") + "\\" + "Audit")))
{
Directory.CreateDirectory(folder + "\\" + DateTime.Now.ToString("MM-dd-yyyy") + "\\" + "Audit");
}
folder = folder + "\\" + DateTime.Now.ToString("MM-dd-yyyy") + "\\" + "Audit";
if (File.Exists(folder + "\\Audit- " + fname + ".xlsx"))
{
File.Delete(folder + "\\Audit- " + fname + ".xlsx");
}
string fileName = folder + "\\Audit- " + fname + ".xlsx";
wb.SaveAs(fileName,
Excel.XlFileFormat.xlWorkbookDefault, null, null,
false, false, Excel.XlSaveAsAccessMode.xlNoChange,
null, null, null, null, null);
This code works perfectly fine 8/10 times and throws network error (Network path not found) other 2 times. When the remote path throws this error I open the above remote path using run command on the machine I run this code and I am able to access it as normal. Closing the folder opened manually and re-running the code is solving the issue. What could be the issue? Am I doing something wrong here?
PS: I also tried to save the excel file onto desktop and then use File.Copy and there is no change to this intermittent behaviour.
Check the following things
1) First you have to check whether machine is on or off
2) Then check you have access rights to put the file in that particular folder and dont
put it inside ' C ' Drive because C is not accessible for other users in network put it inside D or E drive.
3) If Folder is Missing You have to Create A Folder first
and what is ' WB '
if(!Directory.Exists("\\\\testing-path\\Audit\\Reports"))
Directory.Create("\\\\testing-path\\Audit\\Reports");
Use
FilePath Byte
File.ReadAllBytes("FilePath/FileName.Extension",byte) // D:\\Test.xls,12878
then in Remote Location
FilePath Byte
File.WriteAllBytes("FilePath/FileName.Extension",byte)// D:\\Test123.xls,12878

launch = String.Format(launch, directory);
string text = launch;
// WriteAllText creates a file, writes the specified string to the file,

Directory.SetCurrentDirectory(#"C:\windows\system32\");

What am I doing wrong?
Why do you need to call Path.Combine if your whole path is in one string?
Assuming your javaw.exe is actually in C:\windows\system32\, Process.Start("java.exe", launch); should work as intended.

Just use Java's real location instead of "javaw" like "c:\programfiles\Java\jre7\bin\javaw.exe"
I have some code that uses a library for a product called Fusion Pro. Based on some config and data files it will generate a PDF file. I have been getting consistent result of a complete lack of output without any thrown exceptions. However when debugging I have been able to get the PDF to generate by attaching the debugger to the code running in my local IIS and stepping through line by line. Nothing is consistent though. It seems to have a higher success rate if I use F11 instead of F10 and going "slow but steady" through each line. Unfortunately it doesn't always produce a PDF even with stepping through the code.
I have never experienced code behaving so inconstantly with the same inputs each time.
The only other relevant bits of information is this code is working in another asmx service without issue, it is running under a specific domain account (requires special security), and it is running in 32bit mode.
