Using single and double quotes

[DigDeep]

I am always having difficulties to understand how to get the single & double quotes in place.

My script calls the Runwait and completes within secs.

Local $PatchPath = 'C:\temp\DownloadedPatch'
Local $PatchDwn = '\Patch KB number directory' ; example '\4053577'
Local $GetPatch = $PatchPath & '\' & $PatchDwn
RunWait(@ComSpec & ' /c start /wait DISM.exe /Online /Add-Package /PackagePath:' & $GetPatch & '\' & $PatchDwn & '.cab' & ' /quiet /norestart', "", @SW_HIDE)

if I put a MsgBox prior runwait as per below it tells the path and file is correct. So I think I might be doing something wrong placing the single quotes.

MsgBox(0, '', $GetPatch & '\' & $PatchDwn & '.cab')

 

Can someone help me here?

I take the issue back. Few days ago I had declared the $PatchDwn &  '.cab' as an exe file. Script was downloading the exe file but as .cab extension and wasn't able to read it. So wasn't able to install. I have fixed that and it is working fine now.

Sorry for the confusion.

But I would still like to understand the way single and double quotes are placed. If someone can help with the explanation will be of good help.

I think you are overcomplicating things. "Start" isn't needed because this is what RunWait does.
Do you notice that you get double backslash twice in the cmdline?
Can you post what you expect the commandline to look like?

This example will display the commandline as it gets executed.

Local $PatchPath = 'C:\temp\DownloadedPatch'
Local $PatchDwn = '\Patch KB number directory' ; example '\4053577'
Local $GetPatch = $PatchPath & '\' & $PatchDwn
Local $CmdLine = 'dism.exe /Online /Add-Package /PackagePath:' & $GetPatch & '\' & $PatchDwn & '.cab' & ' /quiet /norestart'
MsgBox(0, "Command line", $CmdLine)
; RunWait(@ComSpec & ' /k ' & $CmdLine, "", @SW_HIDE)

@water, it is fixed now as per explained above. And yes, I have removed that Start / Wait also. I had put that to get the command line opened to see if it was giving any errors. That's what helped me to fix it.

Can you help me explaining how to put single and double quotes? If you want I can give some examples...

I believe that’s in the FAQs and also the help file

"Start /Wait" isn't needed either
"/c" in the RunWait statement means "close" the window after execution.
Replace it with "/k" to "keep" the window open after execution so you can check error messages.

Strings and how to enclose them is described in the help file.
