c# Launch process without taking focus

I've created a GUI app that basically loads a video file, launches 3 processes with arguments in sequential order, (ffmpeg, x264, mp4box) and has the ability to abort if needed.
I'm trying to figure out a way to launch these processes without them stealing focus from whatever program is opened. Not necessarily the original form itself...it could be IE, MS WORD, etc...I know about ProcessWindowStyle, however, all options still take focus away. I do not want to start these processes hidden either.
This is an example of my code for starting a process
Process ffmpegProcess = new Process();
ffmpegProcess.StartInfo.FileName = Settings.Default.ffmpeg;
ffmpegProcess.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;
string outputaud = text2 + "_audio.aac";
string AudioBitrate = this.cBAudiobitrate.GetItemText(this.cBAudiobitrate.SelectedItem);
string ffargs = "-i " + quote + SourceFile + quote + " -filter_complex " + quote + "[0:2][0:3]amerge=inputs=2,pan=stereo|c0=c0+c1|c1=c0+c1[aout]" + quote + " -map " + quote + "[aout]" + quote + " -strict experimental -acodec aac -b:a " + AudioBitrate + "k " + quote + outputaud + quote;
ffmpegProcess.StartInfo.Arguments = ffargs;
ffmpegProcess.Start();
while (!ffmpegProcess.HasExited)
{
if (this.bw404p_withaudio.CancellationPending)
{
ffmpegProcess.Kill();
e.Cancel = true;
return;
}
Thread.Sleep(1000);
}
I know about using the Microsoft.VisualBasic Reference and Shell command with AppWinStyle as it has options for launching with no focus, I just can't seem to figure out how to modify my code to make it work with that.
Any ideas?
Thanks

startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

Java (Minecraft) doesnt start from c#

When I copy paste the javaw.exe -arguments to console it works but, when I launch it like this it doesn't work.
string directory = "C:\\Users\\Can\\AppData\\Roaming\\.minecraft";
string java = #"C:\windows\system32\javaw.exe";
string javaLocation = "C:\\Program Files\\Java\\jre7\\bin\\javaw.exe";

launch = String.Format(launch, directory);
string text = launch;
// WriteAllText creates a file, writes the specified string to the file,
// and then closes the file.
Directory.SetCurrentDirectory(#"C:\windows\system32\");
Process.Start("javaw.exe",
Path.Combine(launch));
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"

Use Sharepoint Copy web service to copy folder and contents

I am trying to make a program that copies all of a Sharepoint folder's contents (all subfolders and files) into another Sharepoint folder. Both of these folders will be on the same Sharepoint site.
However, I am trying to do this remotely - if possible*. Therefore, I have tried using the Copy web service without success. The Copy web service appears to only work with copying files, not folders. In addition, I cannot determine a way to iterate through the folder's contents to copy everything - it will only copy one item.
Thank you for any insights or tips,
Scott
*From a custom CRM workflow activity
~~Edited for clarification~~

In the end, I decided to create my own custom web service in Sharepoint that I was able to successfully access from Microsoft CRM. If anyone is interested, I've pasted the C# code I used to copy the folder structure:
public String CopyFolderContents(String sourceURL, String folderURL, String destinationURL)
{
try
{
#region Copying Code
//Get the SPSite and SPWeb from the sourceURL
using (SPWeb oWebsite = new SPSite(sourceURL).OpenWeb())
{
//Get the parent folder from the folderURL
SPFolder oFolder = oWebsite.GetFolder(folderURL);
//Create a list of all files (not folders) on the current level
SPFileCollection collFile = oFolder.Files;
//Copy all files on the current level to the target URL
foreach (SPFile oFile in collFile)
{
oFile.CopyTo(destinationURL + "/" + oFile.Name, true);
}
//Create a list of all folders on the current level
SPFolderCollection collFolder = oFolder.SubFolders;
//Copy each of the folders and all of their contents
String[] folderURLs = new String[collFolder.Count];
int i = 0;
foreach (SPFolder subFolder in collFolder)
{
folderURLs[i++] = subFolder.Url;
}
for (i = 0; i < folderURLs.Length; i++)
{
SPFolder folder = collFolder[folderURLs[i]];
folder.CopyTo(destinationURL + "/" + folder.Name);
}
}
#endregion Copying Code
}
catch (Exception e)
{
#region Exception Handling
String Message;
if (e.InnerException != null)
Message = "MESSAGE: " + e.Message + "\n\n" +
"INNER EXCEPTION: " + e.InnerException.Message + "\n\n" +
"STACK TRACE: " + e.StackTrace + "\n\n" +
"Source: " + sourceURL + "\n" +
"Folder: " + folderURL + "\n" +
"Destination: " + destinationURL;
else
Message = "MESSAGE: " + e.Message + "\n\n" +
"STACK TRACE: " + e.StackTrace + "\n\n" +
"Source: " + sourceURL + "\n" +
"Folder: " + folderURL + "\n" +
"Destination: " + destinationURL;
throw new Exception(Message);
#endregion Exception Handling
}
return "Operation Successful!";
}
All I did was add this method into a Sharepoint web service and called it from CRM and it works.
Thanks to everyone who provided other answers,
Scott

There is a simple solution to this problem , as its just about copy and paste use the simple XCOPY command
XCOPY Copy files and/or directory trees to another folder. XCOPY is similar to the COPY command except that it has additional switches to specify both the source and destination in detail.
To copy a folder including all subfolders
XCOPY C:\utils\* D:\Backup\utils /s /i
here /i defines the destination as a folder
for more detail please refer this link

Inconsistent results during debugging - Web API

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.
DLQueueClient client = new DLQueueClient();
DLQueueJob vdpQueueJob = new DLQueueJob();
string fileName = message.OutputFilePath;
var dataFilePath = CreateDataFile(fileName, message.DefFilePath, message.VariableDataContent, message.QTY);
var pdfFilePath = Path.Combine(new[] { message.OutputFilePath, dataFilePath.Replace(".txt", ".pdf") });
vdpQueueJob.Priority = priority;
vdpQueueJob.Queue = queueName;
string cmd = "\"" + Settings.FusionProExe + "\" \"" + dataFilePath + "\" \""
+ message.DiffFilePath + "\" \"" +
(isProof ? message.ProofConfigFilePath : message.PrintConfigFilePath) + "\" \""
+ pdfFilePath + "\"";
vdpQueueJob.CommandLine = cmd;
client.ConnectRemote(Settings.FusionProServer, Settings.FusionProUser, Settings.FusionProPassword, Settings.FusionProTimeout);
client.SubmitJob(vdpQueueJob, Settings.FusionProTimeout, true);
return pdfFilePath;

Unable to generate file from ASP.NET with inkscape

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.
