ShellExecuteEx()

hello,

i keep getting errors when i run the code from
http://www.codeguru.com/forum/showthread.php?t=302501

i added the appropiate header files, so my code is

Code:

#include <windows.h> int main() { SHELLEXECUTEINFO ExecuteInfo; memset(&ExecuteInfo, 0, sizeof(ExecuteInfo)); ExecuteInfo.cbSize = sizeof(ExecuteInfo); ExecuteInfo.fMask = 0; ExecuteInfo.hwnd = 0; ExecuteInfo.lpVerb = "open"; // Operation to perform ExecuteInfo.lpFile = "c:\\windows\\notepad.exe"; // Application name ExecuteInfo.lpParameters = "c:\\example.txt"; // Additional parameters ExecuteInfo.lpDirectory = 0; // Default directory ExecuteInfo.nShow = SW_SHOW; ExecuteInfo.hInstApp = 0; if(ShellExecuteEx(&ExecuteInfo) == FALSE) // Could not start application -> call 'GetLastError()' return 0; }

the errors i get are:
1>------ Build started: Project: aaa, Configuration: Debug Win32 ------
1>Compiling...
1>aaa.cpp
1>c:\documents and settings\z\desktop\c++\aaa\aaa\aaa.cpp(12) : error C2440: '=' : cannot convert from 'const char [5]' to 'LPCWSTR'

1>aaa - 3 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

what is wrong with my code?
and what do i have to do to fix it?

im also using windows XP

thanks for help in advance, zac

Re: ShellExecuteEx()

The problem is that you are using ANSI strings, but are compiling in UNICODE.

Include <tchar.h> and use the _T() macro.

For example

Code:

ExecuteInfo.lpFile = _T("c:\\windows\\notepad.exe");

Not related but you don't need to use memset anymore. Instead you can let the compiler initialize a structure.

Code:

SHELLEXECUTEINFO ExecuteInfo = { 0 };

And suppose if i create the shorcut of same exe on desktop.then google page gets opened easily without closing the dialog.
Please help me.

SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;

Re: ShellExecuteEx()

You better would open your own thread rather than adding to a solved question.

Also please post your code into code blocks so that we easier can read them.

If you compare your code with that of zaac you'll will see that you didn't initialize the SHELLEXECUTEINFO structure. As Arjay already explained it simply could be done by

Code:

SHELLEXECUTEINFO ShExecInfo = { 0 };

I don't know whether it solves your issue but surely you should try it cause starting form Visual Studio would invoke the debugger which causes all memory to be initialized while starting from desktop might not do it that way.

Thanks for help.
Actually i am new to code guru.I dont how to open a new thread thats why i am doing like this.
Please tell me how to open a new thread.

I had initialized structure to zero also but it does not work.
Code is like this.

SHELLEXECUTEINFO ShExecInfo = {0};

ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = L"open";
ShExecInfo.lpFile = L"iexplore.exe";
ShExecInfo.lpParameters = m_cstrURL;
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOWNORMAL;
ShExecInfo.hInstApp = NULL;

ShellExecuteEx(&ShExecInfo);

if(ShExecInfo.hProcess)
CloseHandle(ShExecInfo.hProcess);

I am not sure what you mean by not working try to use GetLastError() if function get failed .Which will help you to understand the reason of your problem.

Thanks

Use all your powers & all your skills as a 'computer programmer' & try to figure it out. If you can't...well....good luck with programming is all I can say! :rolleyes:

Hint1: you can't do it from the thread page, but can from the forum page.
Hint2: see the 'New Thread' button.

Click on the "Visual C++ Programming" link at the top of this page. A blue "New Thread" button will be on the left just above the list of threads.

Well, since you're so polite being so thankful and all, I'll give you some more advice:

If you can't figure out how to start a thread:
a. On your own.
b. After Arjay's hint #1 & hint #2
c. After Arjay explicitly told you how to...

...then you should just give up programming right now, you aren't cut out for it.

Others on this forum may help you with your ShellExecute problem even though you can't figure out something that's 10 times simpler than that like how to post on a web forum. I personally would consider it a waste of time.

You're welcome.
