Save File dialog with PowerShell/C# from cmd batch

Question

I am trying to get a gui based save file as dialog from within a windows batch script. I would like to have a new folder button left of the save & cancel buttons. With no predefined filetype. So it would probably have to be set to all files. Something similar to this: (Ignore the buttons in the top left) I have found a nice soloution, from the top answer, for opening a file here: File / folder chooser dialog from a Windows batch script It would be nice to have a similar soloution for a save as dialog. Most importantly I would like the ability to set the path & filename to their own variables. For the purpose or sake of the example. We could insert "Hello World" as output. exempli gratia: ``` echo Hello World > %variable.path%%variable.file% ``` The example below is a direct quote from the linked post. ``` :: chooser.bat :: launches a File... Open sort of file chooser and outputs choice to the console @echo off setlocal enabledelayedexpansion :: Does powershell.exe exist within %PATH%?…

Accepted Answer

I managed to get it working myself. Though without the button I wanted for making a new folder. Right clicking involves more steps & forces use of the mouse. Where as the button could be programmed for calling with ALT+N. Nevertheless I basically have the resulting code that I initially sought.

```
:: chooser.bat
:: launches a save file dialog and outputs choice to the console
@echo off
setlocal enabledelayedexpansion

:: Does powershell.exe exist within %PATH%?
for %%I in (powershell.exe) do if "%%~$PATH:I" neq "" (
    set chooser=powershell "Add-Type -AssemblyName System.windows.forms|Out-Null;$f=New-Object System.Windows.Forms.SaveFileDialog;$f.InitialDirectory='%cd%';$f.Filter='All Files (*.*)|*.*';$f.showHelp=$true;$f.ShowDialog()|Out-Null;$f.FileName"
) else (
rem :: If not, compose and link C# application to open file browser dialog
    set chooser=%temp%\chooser.exe
    >"%temp%\c.cs" echo using System;using System.Windows.Forms;
    >>"%temp%\c.cs" echo class dummy{
    >>"%temp%\c.cs" echo public static void Main^(^){
    >>"%temp%\c.cs" echo SaveFileDialog f=new SaveFileDialog^(^);
    >>"%temp%\c.cs" echo f.InitialDirectory=Environment.CurrentDirectory;
    >>"%temp%\c.cs" echo f.Filter="All Files (*.*)|*.*";
    >>"%temp%\c.cs" echo f.ShowHelp=true;
    >>"%temp%\c.cs" echo f.ShowDialog^(^);
    >>"%temp%\c.cs" echo Console.Write^(f.FileName^);}}
    for /f "delims=" %%I in ('dir /b /s "%windir%\microsoft.net\*csc.exe"') do (
        if not exist "!chooser!" "%%I" /nologo /out:"!chooser!" "%temp%\c.cs" 2>NUL
    )
    del "%temp%\c.cs"
    if not exist "!chooser!" (
        echo Error: Please install .NET 2.0 or newer, or install PowerShell.
        goto :EOF
    )
)

:: capture choice to a variable
for /f "delims=" %%I in ('%chooser%') do set "filename=%%I"

echo You chose %filename%
pause

:: Clean up the mess
del "%temp%\chooser.exe" 2>NUL
goto :EOF
```
