Execute batch file + call Visual Studio Command Prompt - tfs

Question

I have a batchfile ( see code below ).
Because the tf command must be executed in the Visual Studio command prompt.
I call the visual studio command.
But then the batch file stops executing.
Somebody have an idea?
REM #echo off
REM ... Change the path below. This is the path where the code will be downloaded!
REM Z:
REM cd Backup_TFS_Preview
call %comspec% /k ""C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" x86
REM ... Navigate to folder
Z:
cd Backup_TFS_Preview
REM ... Makes folder with date today
mkdir %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4%
REM ... Navigate to folder
cd %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4%
REM ... Add workspace for the folder with date of today
tf workspace /new %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4% /noprompt
REM ... Get all items from TFS
tf get /recursive /all /noprompt
REM ... Navigate to folder
cd ..
REM ... Zip the folder
C:\TFS_Backup_Scripts\7z.exe a %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4%.zip %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4%\
REM ... Remove folder
rmdir %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4%\ /s /q
REM ... Delete workspace
tf workspace /delete %Date:~-10,2%-%Date:~-7,2%-%Date:~-4,4% /noprompt
REM ... Navigate to folder
cd ..
cd ..
REM ... Delete zip files that are older then 10 days
forfiles -p "Z:\Backup_TFS_Preview" -s -m *.* -d -10 -c "cmd /c del /q #path"

Answer 1

%comspec% /k runs another command prompt, and then keeps cmd.exe around. Until that cmd.exe returns, your batch file won't continue.
Even if you replace /k with /c (which doesn't keep cmd.exe around), it won't work, because the environment variables from the new command prompt aren't preserved in this one.
You simply need:
call %VS100COMNTOOLS%\vsvars32.bat
Or
call %VS100COMNTOOLS%\..\..\VC\vcvarsall.bat x86

Answer 2

what happens when you execute the call from a cmd prompt?
also note the exit code (0 or 1) for vcvars32.bat (which is called by vcvarsall.bat) so run: Echo %errorlevel%
after you run vcvarsall.bat. if it is zero the command completed successfully.
and you might try and remove the dbl "" like this:
call %comspec% /k "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" x86
that could break the cmd statement up into bad pararameters due to the spaces not being escaped
maybe test for the %errorlevel% right after the call line
last resort, change the /k to /c in the call statement.

I solved it in another way. I used the full path of the tf.exe. And it works in the command prompt.
The call answer doens't worked for me.
