China DOS Union

TO:willsort
There is a problem like this:
@echo off
xcopy \\computername\filename
start e:\dos\name.exe
This batch file runs without any errors!
But after converting it into .com with bat3com, the last line start e:\dos\name.exe cannot be executed!

Re maya0su:

Sorry! It has already been four years since I last used bat2com software, so I cannot be certain about the details. It may be that the command-line parameters of the start command cannot be passed correctly after being compiled by bat2com. If possible, I suggest using Call or directly calling name.exe.

Also, it should be pointed out that bat2com-type software still has major application limitations even now, such as very unsatisfactory handling of redirection and so on. Therefore I generally do not use them to compile batch files. If I had such a need, I would rather choose to use WinRAR to compress it into an executable package and set it to auto-run and auto-delete, though unfortunately if this method is used under DOS, there are still fairly large limitations.

Self-extracting package for a batch program made with WinRAR

Good thread, enjoying it again～：）

Found this by accident!

Bump it up!

Although I haven't had time to read it carefully yet, a good thread like this definitely deserves a bump. We can't let it sink!

Now let us move on to the newer CMD@WinXP. If the directory name contains spaces, then its existence cannot be recognized by using the long filename.


Quote:
C:\>md "my test"

C:\>if not exist "my test"\nul echo Not exist "my test"
Not exist "my test"

C:\>if not exist "my test\nul" echo Not exist "my test"
Not exist "my test"

C:\>

The if command cannot be used to test a directory directly, but the null (NUL) device does in fact exist in every directory. Therefore, the existence of a directory can be determined by testing the null device. The following example can test whether a directory exists:

if exist c:mydir\nul goto process


Using the example from help, a folder with spaces in its name can be detected with a long filename, so perhaps I did not understand the senior member's topic clearly. Since I am a newbie, if there are mistakes in my reply, please forgive me!

My understanding really did have a problem. The error is:
The detection succeeds only when there is no file with the same name as the folder with spaces in it (if the file has an extension, detection also succeeds, unless that file has no extension). Otherwise it fails!
