A problem that has been plaguing me for nearly a week now.
I am trying to get an install of IIS to take place through the command line in VB. I understand that i need to be setting up an Unattended xml script to call, but here is a fundamental bit that is confusing me:
If i run the command : ' start /w pkgmgr /iu:IIS-WebServerRole;IIS-WebServer; ' it executes perfectly within CMD.exe.
If i add the command to a batch file and run the batch file, it runs perfectly.
If i call the command using : Dim myProcess As Process = Process.Start("cmd.exe", "/k start /w pkgmgr /iu:IIS-WebServerRole;IIS-WebServer;"), then it fails with an error of:
////////////////////////////////////////////////////////////////////////////////////////////////////////////
Operation failed with 0x8007000B ////
////
An attempt was made to run the program in an incorrect format ////
////////////////////////////////////////////////////////////////////////////////////////////////////////
If i call the batch file mentioned earlier, then i get the exact same error.
How can it work perfectly with the two first examples but fail when it is called through VB?
Thanks for any help!
Your VB.NET program is very likely to be running in 32-bit mode and will start the 32-bit version of cmd.exe. The one from c:\windows\syswow64 instead of the one from c:\windows\system32 that you used before. Getting BadImageFormatException starts to become likely.
Project + Properties, Compile tab, set the Target CPU to AnyCPU and untick the "Prefer 32-bit" option. On older versions of VS click the Advanced Compile Options button to get to the setting.

I'm using freepascal. So after I run my code compiler creates an exe file that should create few text files. However after it creates an exe file it says "Program c:\fpc\2.6.4\bin\i386-win32\maxmin.exe exited with exitcode = 2". No text files are created. If I later run maxmin.exe manually - it works fine.
UAC - disabled and EnableLUA = 0. But I still pretty sure - it is windows 8.1 rights issue problem.
Some possibilities, in descending order of likeliness:
Note that exitcode 2 usually indicates a file not found error.
Working directory. While manually executing you set the working directory by CDing with the shell, and when indirectly executing the program's assumptions about a working directory are not satisfied.
Sometimes locks linger on Windows for a short while. Usually not noticeable in the manual execution time frames, but when programmatically executing programs in quick succession it might happen.
If you have the feeling that the EXE doesn't run at all, it might be an security software issue. After the binary is generated, the antivirus kicks in and wants to scan, locking the binary for a few seconds.
i am trying to execute netcfg.exe /U ms_pacer etc to uninstall some bindings to the network adapter. now everytime i pass the command through vbscript the command prompt throws an error saying 'netcfg.exe' is not recognized as an internal or external command, operable program or batch file.
if i put it in a batch file and double click on it it runs fine. but again if i execute that batchfile through a .run in vbscript it gives the same error. i read somewhere that it could be environment variable issue, but tried setting environment, looks good but the command keeps throwing the error again and again. tried it in powershell but no go, please someone guide.
Ok found the answer, when running a 32 bit compiled application which needs to access another native windows application there is a catch. though windows has provided a set of 32-bit set of native applications in a 64 Bit OS, but has not changed names of files, and have been relocated in another folder i.e. %windir%\SysWoW64\ , now everytime a 32 bit application tries to access c:\windows\system32 on a 64 bit, it gets redirected to %windir%\SysWoW64\, now if one wants to refer to 64 bit native application then do %windir%\Sysnative
I have 5 scheduled tasks that are scheduled to run every day at 9.30am. The schedule is basically a vbs script that opens an excel workbook and runs a macro. These 5 schedules can run fine if i run them seperately and 9 times out of 10 they run fine if I simulataneously run them from task scheduler. I do this by highlighting them all and then pressing run.
But sometimes when the task scheduler is doing its schedule they will fail. Sometimes all of them fail, sometimes some of them fail, but most of the time they all succeed.
Once I okay the errors(will post this next time it occurs) I can see the excel.exe in my Processes in TaskManager they are left hanging. I cannot see them in Applications because I run them in the background. Whilst here I know I can right click on the excel.exe and do a Create Dump file, but not sure what to do with this.
What I am interested here is discovering why they are failing? How do I debug it? Can I get a dump? how do i do this? I am sure the code is not perfect but the fact that they run fine seperately and most of the time fine together I am wondering is some memory resource getting used up at this time. This is what I would like to find out.
I know that i could space them out to run every minute, and this is something I might do but I would like to answer my questions above first.
Note: The vbs script in question can be found here in a previous question I asked.

EDIT3 : A useful walkthough example with commands
Crash Dumps
Load in Windbg. Then File menu - Open Crash Dump. Type !analyze (note wrong spelling)
Debugging
You can also start in a debugger.
windbg or ntsd (ntsd is a console program and maybe installed). Both are also from Debugging Tools For Windows.
Download and install Debugging Tools for Windows
http://msdn.microsoft.com/en-us/windows/hardware/hh852363
Install the Windows SDK but just choose the debugging tools.
Create a folder called Symbols in C:\
Start Windbg. File menu - Symbol File Path and enter
srv*C:\symbols*http://msdl.microsoft.com/download/symbols
then
windbg -o -g -G c:\windows\system32\cmd.exe /k batfile.bat
You can press F12 to stop it and kb will show the call stack (g continues the program). If there's errors it will also stop and show them.
Type lm to list loaded modules, x ! to list the symbols and bp symbolname to set a breakpoint
If programming in VB6 then this environmental variable link=/pdb:none stores the symbols in the dll rather than seperate files. Make sure you compile the program with No Optimisations and tick the box for Create Symbolic Debug Info. Both on the Compile tab in the Project's Properties.
Also CoClassSyms (microsoft.com/msj/0399/hood/hood0399.aspx) can make symbols from type libraries.
You can schedule this command line instead.
Autostarting Programs in Debugger
You can also make windbg attach to any specific program when started. See gflags.exe. Only in GUI mode.
Errors
Also get the error number. TS keeps a history of runs and their errors. TS has a history tab.

I'm writing a script for Illustrator CS6 in ExtendScript. At the end of my script, I want to spawn a task (a second script, in Ruby) using File.execute(). However, it's not working. And I'm at a loss as how to debug the problem -- how can I figure out why this isn't working?
Here's the end of my ExtendScript file:
// Do a bunch of other work, then:
var rubyFile = new File(scriptFolder + 'BuildHtmlWalkthrough.rb');
alert(rubyFile.exists);
var result = rubyFile.execute();
alert(result);
Both rubyFile.exists and result are always true, indicating that the script launched OK. But the script does not appear to run, at all. I've tried the following diagnostics:
The Ruby script does successfully run from the command line. The script's permissions are -rwxr-xr-x
I added a call to system("touch /blah/blah/blah") as the very first line of the Ruby script. The file does not get touched.
I thought maybe the ExtendScript process was terminating before the Ruby script could run, so I added a long for loop after rubyFile.execute(). Spinning for > 30 seconds did not help.
What can I do to debug, or solve, this problem?
I'm on MacOS X v10.9.1. And for reference, this is the documentation for File.execute():
File.execute (): Boolean
Core JavaScript Classes
Executes or opens
this file using the appropriate application, as if it had been
double-clicked in a file browser. You can use this method to run
scripts, launch applications, and so on. Returns true immediately if
the application launch was successful.
It's probably doing the "opens this file using the appropriate application" instead of executing, and returns true because the file successfully opens (or is already open in its associated app). If I have a python script and do
f= new File("~/Documents/misc_scripts/getpixelrgb.py");
f.execute();
, it opens it in my script editor, even if the file's execute flags are set.
I'm on OSX, btw
In After Effects, there is system.callSystem() to execute command line commands, but I'm afraid that is absent in Illustrator (I'm assuming you're doing this for Illustrator because of the tag). Are you on OSX or Windows? There are ways around this, by making an executable .app (OSX) or .exe (Win) and calling that with execute(). If I were doing this, I'm on OSX and I'd make an AppleScript app that does 'do shell script' to make the ruby system call. On Windows, it's different. One solution you might like if you're on windows: ocra, which is ruby-specific (http://ocra.rubyforge.org/). It may be possible to run a .bat file on Windows that calls the ruby script, but I'm not sure.
[edit!]
Terribly sorry for the extraneous Windows info (for someone else, I guess). Just saw your note about being on OSX. So you might want to use the AppleScript solution.
[edit again]
So, if my ruby script ("test.rb") is:
#!/usr/bin/env ruby
print "Hello"
and my AppleScript is:
do shell script "cd /testing_folder/; ruby test.rb"
Then I get "Hello" returned in AppleScript, but ExtendScript will just return true.
I have an ancient COM object in VB6 that has been working fine until recently. (Don't they all). The only code change that has been made (as verified by svn) is the inclusion of a new string literal in an array.
The VB6 IDE compiles the object fine. When I hit Run|Start... and execute the following test vb script from the command prompt, the object works fine and I see the dialog boxes I expect:
dim o
set o = CreateObject("MyDll.MyClassName")
wscript.Echo "Testing object"
wscript.Echo o.HelloWorld ' runs a test method that returns "Hello World"
wscript.Echo "Done"
However, when I stop debugging in the IDE and attempt to run the same vbscript from the same command prompt, I get the error:
(ProgID removed for security reasons, but it is the same as in the script.)
Things I've tried:
I suspected that the DLL may have been registered and unregistered by VB when I start and stop the debugger, so I also tried registering the object with regsvr32 before running the test script. This has had no effect.
I also removed all references to the DLL from the registry, and re-registered the object. Same error.
I deleted the DLL and re-built it from VB (File|Make...) and re-registered the DLL. Same error.
Machine is Win7 Ultimate x64, object built with VB6.
Any suggestions?
And, no, unfortunately, rewriting the object in C# isn't an option.
Microsoft says it's some sort of dependency issue: http://support.microsoft.com/kb/194801
Because it's working when you run the object in the IDE this leaves you with four possibilities:
The ActiveX dll itself is not on the system path.
The ActiveX dll depends on something else which is not on the system path.
After registering the dll, it is somehow marked as requiring elevated security to run
After registering the dll, something it depends on requires elevated security to run.
I would try opening a command prompt as administrator then run your vbscript file that starts the object. If that works then it means the problem is either #3 or #4. If it doesn't, then it means #1 or #2.
You can eliminate #2 and #4 if the ActiveX dll has no external dependencies.
Next, I'd look in my event log to see if any other errors were logged by windows about this.
UPDATE
Just found another possible cause. If the ActiveX dll is 32-bit, then the script has to use the 32-bit version of the script engine to run; otherwise it will give this error because the default script engine (x64 on that machine) literally can't find the dll.
I believe if you use \windows\system32\cscript.exe to run your vbscript then you'll be good.
Well it definitely sounds like the issue because of 32bit dll.. The suggestion mentioned above is correct but the path is wrong.. try using the CSCRIPT from C:\Windows\SysWOW64..
Try registering the DLL with regsvr32.exe from %Windows%\SysWOW64. It is different than the regsvr32.exe in %Windows%\System32 (on a 64-bit OS).
See this SO posting.
