batch file question

[PT Exorcist]

How can i concatenate 2 strings in a batch file? I have for example "abc" and "def", and i want to turn it in "abcdef". How should I do it?

Note that I really HAVE that quotes in the string, how do I take them off?

The double quotes write to a file when you use the Write file operator. Change it to something
like ... Print #1, "abc" and you will get in your batch file abc.

I dont want to write to a file, I just want to have something like a var..is it even possible at all in a batch file?

My batch file will receive as arguments this: "C:\" and "lol.jpg"
and i want it to be able to call my other program with this as argument "C:\lol.jpg"

as another question, is there any command in batch files to convert a short filename to a long filename?

as a yet another question, is it possible at all in the registry to pass as a argument (in folder extension thing) only the path of clicked file, or only the filename instead of passing the full pathfilename?

[RobDog888]

In your batch file you can receive passed parameters like so...

REM %1 = SomeFileNameToSearchForWithAnyExtension
Dir %1.* /s

This takes a parameter of a filename without the extension to do a search for
in the DOS command window. The "%" sign is like a variable to receive
passed parameters from the command line or shelled parameters, etc.

You are not getting my point. If i have a "C:\" path and try to search for the wildcard "*.jpg" I can't just put

Dir %1%2 as it will result as "C:\""*.jpg"

It worked for me. Here is my demo code.

Option Explicit
 
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, _
ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
 
Private Const SW_SHOWNORMAL As Long = 1
 
Private Sub Command1_Click()
    Open "D:\Development\Test2.bat" For Output As #1
        Print #1, "Dir %1%2.* /s"
    Close #1
End Sub
 
Private Sub Command2_Click()
    ShellExecute Me.hwnd, "Open", "C:\Windows\System32\Cmd.exe", " /K D:\Development\Test2.bat D:\Development\ Test2", "D:\Development", SW_SHOWNORMAL
End Sub

You are still not getting my point...the text thats being passed has quotes AROUND IT so what I get is not C:\ like in your example but it's "C:\"

[PT Exorcist]

Anyone...?

[RobDog888]

Can you post your code, maybe there is some other reason. If you are receiving it like "C:\""*.jpg" then
it must be the way your passing it or in your batch file your placing double quotes around the variables?

[PT Exorcist]

The program that's giving the "C:\" as argument can't be changed, so I just have to work with it.

What I need is some kind of way of manipulate strings through the batch file so I can take the quotes off and just do %path_without_quotes/*.jpg like you said

[RobDog888]

If you could strip out the double quotes before they are sent to the batch file then you could use the vb Replace
function. I dont think that there is a way to do it in DOS but I will look.
