ShellExecuteEx()

[zaac]

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

#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'

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

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

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

For example

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.

SHELLEXECUTEINFO ExecuteInfo = { 0 };

If might help us if you posted some relavent code using code tags.

Sry for being late.
i am still getting the same problem.
help me..

hi all,

I had a weired behavior in my application. when run any exe on desktop and dialog box of my application appears on which a hyperlink is there and when clicked on hyperlink google page gets opened .But problem is that google page does not get open till i do not close the dialog.and when i close the dialog google page gets opened easily.
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;

ShExecInfo.lpFile = m_bExplore ? L"explorer.exe" : 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);

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

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!

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

Hi..
I had tried GetLastError(),Shellexecuteex is executing sucessfully.
