How can I use ShellExecute() with if and else commands?

Hello

Very simple problem I have here.

If network share is found, open it in explorer. Else open LocalFolder1. If LocalFolder1 isn't found, open LocalFolder2.

Current code;

Code:

---

#include <windows.h>
#include <tchar.h>
#include <iostream>

int APIENTRY WinMain(HINSTANCE hinstance, HINSTANCE hprevious, LPSTR cmdline, int cmdshow) {

        ShellExecute(NULL, "explore", "\\\\panarchy\\share", NULL, NULL, SW_SHOWNORMAL);

        return 0;
}

---

Please tell me how to use Programming Controllers within the above code.

Thanks in advance,

Panarchy

You can do something like:

Code:

---

int APIENTRY WinMain(HINSTANCE hinstance, HINSTANCE hprevious, LPSTR cmdline, int cmdshow) {
  if (GetFileAttributes(szFilePath) != 0xffffffff) {
      ShellExecute(NULL, "explore", szFilePath, NULL, NULL, SW_SHOWNORMAL);
  } else if (GetFileAttributes(szFilePath2) != 0xffffffff) {
      ShellExecute(NULL, "explore", szFilePath2, NULL, NULL, SW_SHOWNORMAL);
  }
  return 0;
}

---

Thanks

However, I don't understand. Where do I define szFilePath?

Please tell me where to define it.

Thanks in advance,

GetFileAttributes() is used to get the file attributes of a given file/folder.


The "szFilePath" is a valid path to the file or folder.

in your case its Hard-Coded as "\\\\panarchy\\share"

Its not a good practice of Hard-Coding. You may search for an API which retrives you the Share folder of current user :)

You can check the return value of ShellExecute() API with if...else conditions

Code:

---

HINSTANCE hInst_1;

hInst_1 = ShellExecute(NULL, "explore", "\\\\panarchy\\share", NULL, NULL, SW_SHOWNORMAL);

                if( hInst_1 > 32 && hInst_1 ! = 0 )
                      {
                            // Function call Sucessful
                      }
                  else
                      {
                            // Function failed, or An error is returned!
                      }

Hopes this helps.. :)

Hello

Thanks for replying.

The UNC Path \\\\panarchy\\share is for the External hard-drive, which, always has that aforementioned UNC Path.

I'm still a little confused, so the following would be correct?

Code:

---

HINSTANCE hInst_1;

hInst_1 = ShellExecute(NULL, "explore", "\\\\panarchy\\share", NULL, NULL, SW_SHOWNORMAL);

                if( hInst_1 > 32 && hInst_1 ! = 0 )
                      {
                            // Function call Successful
                      }
                  else
                      {
                            // Function failed, or An error is returned!
                      }
hInst_2 = ShellExecute(NULL, "explore", "C:\\Backup", NULL, NULL, SW_SHOWNORMAL);

                if( hInst_2 > 32 && hInst_2 ! = 0 )
                      {
                            // Function call Successful
                      }
                  else
                      {
                            // Function failed, or An error is returned!
                      }

---

From looking over what I've written, it's obvious I don't understand!

Could you please explain again?

Thanks in advance,

Panarchy

PS: Perhaps an example with 3 folders? (1 UNC and 2 complete paths)

EDIT: Perhaps something more like this?

Code:

---

HINSTANCE hInst_1;

hInst_1 = ShellExecute(NULL, "explore", "\\\\panarchy\\share", NULL, NULL, SW_SHOWNORMAL);

                if( hInst_1 > 32 && hInst_1 ! = 0 )
                      {
                            // Function call Sucessful
                      }
                  else
                      {
                            ShellExecute(NULL, "explore", "C:\\Backup", NULL, NULL, SW_SHOWNORMAL);
                            // Function failed, or An error is returned!
                      }

---

Well, the code is pretty much complete now;

Code:

---

#include <windows.h>
#include <tchar.h>
#include <iostream>

#ifdef UNICODE
#define tcout wcout
#else
#define tcout cout
#endif

int APIENTRY WinMain(HINSTANCE hinstance, HINSTANCE hprevious, LPSTR cmdline, int cmdshow) {

    STARTUPINFO si = {0};
    PROCESS_INFORMATION pi = {0};
    TCHAR lpCmdLine[MAX_PATH] = {0};
    ::ExpandEnvironmentStrings(_T("\"&#37;ProgramFiles%\\Symantec\\LiveUpdate\\LUALL.exe\""),
                              lpCmdLine, MAX_PATH);

    std::tcout << _T("Command line : ") << lpCmdLine << std::endl;

    BOOL bRet = ::CreateProcess(NULL, lpCmdLine, NULL, NULL, FALSE,
                              CREATE_NO_WINDOW, NULL, NULL, &si, &pi);

    ShellExecute(NULL, TEXT("open"), TEXT("explorer"), TEXT("\\Panarchy\\share"), NULL, SW_HIDE);
    ShellExecute(NULL, TEXT("open"), TEXT("control"), TEXT("schedtasks\0"), NULL, SW_HIDE);
    ShellExecute(NULL, TEXT("open"), TEXT("control"), TEXT("sysdm.cpl"), NULL, SW_HIDE);
    ShellExecute(NULL, TEXT("open"), TEXT("diskmgmt.msc"), NULL, NULL, SW_HIDE);

    {
        if( reinterpret_cast<int>(ShellExecute(NULL, "explore", "\\\\panarchy\\share", NULL, NULL, SW_SHOWNORMAL)) <= 32)
            if( reinterpret_cast<int>(ShellExecute(NULL, "explore", "D:\\BackYouUp\\", NULL, NULL, SW_SHOWNORMAL)) <= 32)
            {
                ShellExecute(NULL, "explore", "C:\\Backups\\bac\\", NULL, NULL, SW_SHOWNORMAL);
            }
    }

    return 0;
}

The only caveat is that it takes a while for the program to process the ifs. If anyone knows a way around that, I'd appreciate it. If not, then the program is complete.

Panarchy

Are you sure... that its the if's causing trouble??

Better way to track is by putting a break point 2 or 3 lines above the suspicious area... and go through each lines. :)

by the by, i cant understansd the logic of using that reinterpret casting template for the ShellExecute function, as you can directly eveluate return value because th function itself returns an integer. :confused:

I know for certain that it is. As the only thing I've added recently has been the ifs.

I've been recommended to convert the program to a multi-threaded one. Could you help me do so?

Thanks in advance,

Panarchy

lol.. i Cant help ;) ...jus kidding....

but.. CreateThread() API can help you... :)

Read the MSDN Documentation for the API. There is a Pretty good example too...

Actually... i dont understand the need of creating this small program as Multi-Threaded... :confused:

maybe i'm wrong.. but i didnt find any big modules... a single thread seems to be enough.. :)

anyway, do so.. if you've got an advice from an expert...

Hi

I don't know how to!

Could you please help me make program multi-threaded?

Thanks in advance,

Panarchy

How do I input error handling within the programming [if, else, etc.] controllers?

Would appreciate your knowledge of how this could be done, within an example.

Thanks in advance,
