i.e result = "Hellow this is a Text".

You can't use LPCSTR here because of the constantness. But how about this:

LPTSTR result[150];<br />
_tcsncpy(result, str.GetString(), 150);<br />

hi christopher,

i am getting this type of error as i copy your code. please help me out.

'_tcsncpy' : cannot convert parameter 1 from 'LPSTR [150]' to 'char *

The person that replied to you made a typo, the code should be:

TCHAR result[150];
_tcsncpy(result, str.GetString(), 150);

If you are using a CString, you there is a built in operator that will return an LPCTSTR, so you do not have to use GetBuffer(...) or anything like that to get a const pointer.

Peace!

When using a method that is specific to a particular VC++ version, it helps to state such.

From MSDN

// example for CString::GetBuffer
CString s( "abcd" );
#ifdef _DEBUG
afxDump << "CString s " << s << "\n";
#endif
LPTSTR p = s.GetBuffer( 10 );
strcpy( p, "Hello" ); // directly access CString buffer
s.ReleaseBuffer( );
#ifdef _DEBUG
afxDump << "CString s " << s << "\n";
#endif

I have found this page usefull when I convert between different types:
http://www.codeproject.com/cpp/data_conversions.asp[^]

There you will find many other conversions as well.

why don't you just do :

CString str = "hello world";
 
(LPCSTR)str;    // used as you like
                // either used with strcpy to be copied, or passed as a function parameter

what happen if we use inline keyword before main().
is it allowed? if yes how what will be behavior of programm

toxcct23-Jan-07 2:18

23-Jan-07 2:18

inline doesn't enforce the function to be actually inlined.
it's up to the compiler to decide if the function is simple enough.
moreover, the main goel in inlining functions is for earning some call time when the function is called multiple times ; main is called once AVAIK !

Unless it is called recursively, which I've seen people do.

Using the keyword inline before a function does not necasserily mean it will be inline, it is more like a request to the compiler. In the case of main() the request would be declined.

Re: Microsoft Outlook: "A Program is trying to send email.."

23-Jan-07 0:48

I have a program that automatically shall send alot of emails through Outlook, and I want to get rid of the warning "A Program is trying to send email..." that pops up everytime you try to send an email.
First of all.. I know there are programs available that I could try and use like "ClickYes" and "Quick-Merge".

However I do not want to rely on another software to do the stuff for me. What I want to do is to add a hook that sees when the security warning dlg comes up and then closes it automatically by pressing the yes buttton before the five seconds are up.

I have tried the following and it almost works:

BOOL CALLBACK EnumAppearanceChildProc2(HWND hwnd, LPARAM lParam)
{
	TCHAR buff[512];
	GetWindowText(hwnd,buff,512); 
    if(_tcscmp(buff,_T("Yes")) == 0)
    { 
        *reinterpret_cast<HWND*>(lParam) = hwnd;
        return FALSE;
    }
    return TRUE;
}
HWND GetYesButton(HWND hWndParent)
{
	HWND hWnd = NULL;

	EnumChildWindows(hWndParent, EnumAppearanceChildProc2, 
		(LPARAM)&hWnd);
	return hWnd;
}

LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam)
{
	if(nCode == HCBT_ACTIVATE)
	{
		HWND hWnd = (HWND) wParam;
		TCHAR buff[512];
		GetWindowText(hWnd,buff,512);
		if(_tcscmp(buff,_T("Microsoft Office Outlook")) == 0)
		{	
			SetWindowText(hWnd,"Correct Window");
			HWND YesButton=GetYesButton(hWnd);
			SetWindowText(YesButton,"Correct Button");
			EnableWindow(YesButton,true);
			Sleep(100);
			PostMessage(YesButton,BM_CLICK,0,0);  // Does not work!!
			g_hWndEffects = hWnd;		
			UnhookWindowsHookEx(g_hook);						
		}
	}
}

In the main program I then call:
g_hook = SetWindowsHookEx(WH_CBT, CBTProc, g_hModule, 0);

This code finds the window and automatically activates the yes button in the security dialogue, but the press command that I send has no effect. If I click the button myself with the mouse the yes button has effect and it can be pressed before the five seconds is up.

Can anybody explain why the press in my code has no effect?

1. edit your message and move your code block into a <pre></pre> tags block Suspicious | :suss:

2. why do you add line breaks by hand ?

3. don't do what you're trying to do. this is a security reason. let the user know that your application uses his email id to send mails.

1. I dont have any pre /pre tags block. Normal C++ code.
2. To make it look nice? Smile | :)

3. It is a user request to add it. The program is sending hundreds of emails. Waiting 5 seconds per email will take considerable time, the problem has to be solved somehow.

it doesn't, it breaks the line in the middle of my screen !

then your application is badly designed. you shouldn't use Outlook for that then...

i think some APIs exist to send mails without having a particular client (like outlook) installed. you only have to know how to connect to the SMTP server....

I have had limited success with these APIs. The ones that I have gotten to work only works for internal email at the firm, when adding outside mail adresses they have all failed. With Outlook solution all mails have successfully reached the destination, but ofcourse with the cost of the security warning.

Use MAPI, SMTP, or CDO then. Trying to bypass Outlook's security is a bad idea.

Note the following remarks from MSDN:

If the button is in a dialog box and the dialog box is not active, the BM_CLICK
message might fail. To ensure success in this situation, call the SetActiveWindow
function to activate the dialog box before sending the BM_CLICK message to the button.

Note that I have had limited success is using the BM_CLICK message, but often do well using BN_CLICKED - which is a good old fashioned WM_COMMAND based notification.

Peace!
