::ShellExecute - Problem passing arguments
-
Hi there. I have an Console based Exe (ABC.exe) that takes some parameters. Now, I want to call this Exe from some other application and want to pass the paremeters as required. Problems: 1. I am calling this exe as below
HINSTANCE hInst = ::ShellExecute(NULL, L"open", L"C:\\Documents and Settings\\pankaj.bhalla\\Desktop\\ABC.exe", L"Hello", NULL, SW_SHOW);
ABC.exe application got launched but text "Hello" never got displayed on the console. 2. In place of this hardcoded text i.e., "Hello", incase I want to send some text stored in CString type variable then how can I do that. Help will be really appretiated. Thanks PanB

What is the target application doing with the parameters passed on to it? Is there any code for displaying it or not? :rolleyes:

You can pass the
CStringvariable as the fourth parameter as it is, becauseShellExecuteis expecting anLPCTSTRthere andCStringwill be automatically casted there.It is a crappy thing, but it's life -^ Carlo Pallini

Why would it be displayed on the console ? Are you retrieving it in the code of your application and prining the argument ? If yes, it's the argument at index 1, and not 0 that you have to use (the first argument is always the path to your application).

Just pass the CString object.

I am basically passing a path to a file. Target application just check whether file exists, if does not then create that file.

You can as well create the file from the calling application as well. Why are you needing to have an executable solely for this? Or is there anything else? If the file copying takes too long and that leaves you with a frozen UI, just spawn a thread. Can't you? You haven't answered my question: Is the target application handling the command line passed on to it? Without that being done, how will it display the command line?

Let me provide few details... 1. Lets say ABC.exe just cout the text provided as an argument. 2. If I launch ABC.exe from console, >ABC.exe Hello, it prints out Hello on the Screen. 3. if I call the same application like HINSTANCE hInst = ::ShellExecute(NULL, L"open", L"C:\\Documents and Settings\\pankaj.bhalla\\Desktop\\ABC.exe", L"Hello", NULL, SW_SHOW); ...it does not Just FYI, ABC.exe is a Console based Application

Is the calling application also a console app? If not, does it open a new console window?

You must show us the target application's code, where you've handled the command line passed on to it.

You must have the final release. I tried it with Beta 3 of abc.exe and the output was "Get lost" instead of "Hello"...

Does the console window open at all?
