Hello,

I am trying to pass file path as command line argument. If the path without spaces it works fine. with spaces it is not.
Please find my code below.

C#

string scriptFilePath =  "@" + Directory.GetCurrentDirectory() + "\\" + scriptFile; // exact path
string scriptPath= " \"" + scriptFilePath + "\""
string file1 = "D:\New Folder\file1.png";
string file2 = "D:\New Folder\file2.png";
string outPutPath = "D:\New Folder\Output\Report.html";
string commandText = "executable.exe" + scriptPath + " " + "\"" + file1 + "\"" +" " + "\"" + file2 + "\"" + " " + "\"" + outPutPath + "\""
ProcessStartInfo startInfo = new ProcessStartInfo();
                    startInfo.WorkingDirectory = @exePath;
                    startInfo.FileName = "cmd.exe";
                    startInfo.RedirectStandardInput = true;
                    startInfo.UseShellExecute = false;
                    startInfo.WindowStyle = ProcessWindowStyle.Hidden;
                    startInfo.CreateNoWindow = true;
                    startInfo.Arguments = commandText;
            try
                    {
                        proc = Process.Start(startInfo);                        
                        return true;
                    }
                    catch (Exception ex)
                    {
                        return false;
                    }

Please help me out if am missing anything.
Thanks.

You are using CMD to execute it; note that you need to use the /c argument to tell CMD that you want to run something, like this:

cmd.exe /c executable.exe arguments here

You can prepend your commandText string to /c to solve this:

C#

string commandText = "/c executable.exe" + scriptPath + " " + "\"" + file1 + "\"" +" " + "\"" + file2 + "\"" + " " + "\"" + outPutPath + "\"";

Hello,
Thank you for your reply. I tried it that doesnt solve my problem.

In that case, it might be a problem with the executable.exe file, but as I don't know what's in there, I cannot look for the problem.

Hi, Here the requirement is I have to run a script file( to compare two image files) in BCompare.exe. So, am running the script in BCompare.exe through command prompt.
For better understanding I will repost my code.

My command to be executed in command prompt is

BCompare.exe @D:\Script\ScriptFile.txt D:\New Folder\file1.PNG D:\New Folder\file2.PNG D:\New Folder\Output\Report.html

file1 & file2 are arguements passed to the scriptFile.txt, which will generate Report.html in the path specified.

My c# code is
string scriptFilePath = "@" + string.Format("\"{0}\"", "D:\\Script\\ScriptFile.txt");
string file1 = @"D:\New Folder\file1.png";
string file2 = @"D:\New Folder\file2.png";
string outPutPath = @"D:\New Folder\Output\Report.html";

string commandText = "/c " + "BCompare.exe" + scriptFilePath + " " + file1 + " " + file2 + " " + outPutPath;
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WorkingDirectory = @exePath;
startInfo.FileName = "cmd.exe";
startInfo.RedirectStandardInput = true;
startInfo.UseShellExecute = false;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.CreateNoWindow = true;
startInfo.Arguments = commandText;
proc = Process.Start(startInfo);
proc.WaitForExit();

I never used BCompare, so I'm afraid I cannot help you with that, I'm sorry.
