Cmd File can´t run on Process.Start(Filename);
I have a Code which has the right Filename (Folder included), and I am trying to run it it through Process but it simply doesn´t work. How can I make it so it runs perfectly. The cmd code itself is completely correct - it works without any Problem...

When you ask a question, make sure you include as much detail as possible. Such as code, the issue you are facing, what you expect the result to be, what .NET version you are using and what platform/environment (if any) are relevant to your question.

Ok I will elaborate: I use JPEX´s decompiler on CommandLine - specifically the Java Version - you can find it here: https://github.com/jindrapetrik/jpexs-decompiler, and here is the documentation on how to work on command Line: https://github.com/jindrapetrik/jpexs-decompiler/wiki/Commandline-arguments.

My C# Code is:
just a Process.Start(BatchFileFOlder) //- the folder is correct
This is the Full code without the main method
string swfFile = Path.Combine(Foldername, Path.GetFileNameWithoutExtension(Filename) + ".swf");
string OriginalFlashPlayer64 = Path.Combine(AppDomain.CurrentDomain.BaseDirectory + @"FFDEC\FlashRunner\ORIGINALFLASHRUNNER\ruffle-nightly-2025_03_25-windows-x86_32", "ruffle.exe");
string NewFlashPlayerPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory + @"FFDEC\Converted" + Path.GetFileNameWithoutExtension(Filename) + ".exe");
File.Copy(OriginalFlashPlayer64, NewFlashPlayerPath, true);
string NewFileToDeleteAfterConversion = Path.Combine(AppDomain.CurrentDomain.BaseDirectory + @"\FFDEC\Converted" + Path.GetFileNameWithoutExtension(Filename) + ".swf");
File.Copy(swfFile, NewFileToDeleteAfterConversion, true);
string BatchFile = Path.Combine(AppDomain.CurrentDomain.BaseDirectory + @"FFDEC", "ConvertSWFTOEXE.cmd");
File.WriteAllText(BatchFile, "cd");
File.AppendAllText(BatchFile, "\nffdec -swf2exe wrapper "" + NewFlashPlayerPath + "" "" + NewFileToDeleteAfterConversion + """);
string CopiedFlashPlayerPath = Path.Combine(Foldername + Path.GetFileNameWithoutExtension(Filename) + ".exe");
Process.Start(BatchFile);
File.Copy(NewFlashPlayerPath, CopiedFlashPlayerPath, true);

This is just a example of how it looks Like, I made a FLASHRUNNER Folder and added ruffle into it. I didn´t specify my whole Project here - my Problem is that is is too big to show it here I would need Discord Nitro - but I don´t need it
The Names are completely correct and I checked the cmd File. If I open the File that has been created it runs perfectly but if I try to run it with C# it doesn´t work
It's probably the case that your
.cmd file isn't actually an executable? So you're trying to execute the file, but that won't work. You need to ask Windows to find a suitable interpreter to execute the file for you, and to do that you need to pass UseShellExecute = true
But, I don't understand why you're writing a cmd file at all. Why not just run nffdec (or whatever you're running, the code is hard to follow) directly?
I'm also not really clear on what you're copying where and why, and that might be messing up somethingThe Problem is that it needs Command Line Input to convert a File Format into another and that is what i am doing here- but thanks for the help I will look into that
What exactly do you mean by "Command Line Input"?
it needs the following string to work as I want it :nffdec -swf2exe wrapper "FlashPlayerPath" "FlashFile" - this is how it converts a swf File into an .exe
I will look into the Use Shell Executive and try to find a solution
"Needs" in what sense? Passed as a command-line argument, or passed on its standard input?
(The
Process class lets you do both, of course)if I want to convert my file I would need to write that with cmd directly but it can also be done by making a cmd File which i did and by running the code via C#, as I am making a Converter out of it
It works when I open the cmd file normally
I'm not sure what you're trying to say. If you want to call
nffdec -swf2exe wrapper "FlashPlayerPath" "FlashFile", then you can do Process.Start(@"Path\To\nffdec", "-swf2exe wrapper \"FlashPlayerPath\" \"FlashFile\"") or similar
See some of the examples on https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.process?view=net-9.0
If you need to set the working directory that you call that in, you can use ProcessStartInfo.WorkingDirectoryNo I just want to run the cmd File that is my Problem not that I could run it directly via C# with the thing you told me - but I will surely look into that too
I'm saying, you're making your life a lot harder by trying to write C# code that creates a .cmd file and then executes it. There are a bunch more things that can go wrong
I've been doing this for a long time. Trust me.
ok
There's absolutely zero point in going to all the bother of writing out a cmd file containing something to run, and then trying to execute the cmd file, when you can just run the thing you want to run directly
well yeah that is true 🤔
you are absolutely right 🙂
I will try that
You're just introducing more places where something can go wrong, and making it a lot harder to find the problem when something does go wrong. Like right now: we don't know where the problem is, because there are so many parts to the chain of things which need to happen
yup
that is true 🙂
thanks I will look into it
