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);
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 
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? 
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.

i meant HTML in your message, not in your source code

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...

1-2. No comments.
3. Nope, not bad design since it is the only option that will work on our system.

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.

Bypassing security is both a bad idea and a lot of fun. I thought bypassing microsoft security was something that all of us find funny

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!

Thanks for the tip, but unfortunately it does not work even when I add SetActiveWindow(hWnd); to the code or replaced BM_CLICK with BN_CLICKED, the Postmessage just do not have any effect

You cannot just replace BM_CLICK with BN_CLICKED - you have to use WM_COMMAND as the message, the button's HWND as the LPARAM and the button's dialog control ID and BN_CLICKED as the WPARAM, wrapped into a WORD value. Look up the BN_CLICKED notification in MSDN for more information.

Sorry my mistake, should ofcourse have checked the manual before . But even when trying "SendMessage(hWnd, WM_COMMAND, MAKELONG(0x12A6, BN_CLICKED), (LPARAM)YesButton);" which should be the right way to send the message the Sendmessage/Postmessage has no effect on the button (with ActiviteWindow as hWnd). Anyone has more ideas?

I recently ran into this same problem but for entirely different reasons. I was using this article's[^] code for doing unattended sending of email. After a new XP image was placed on the PC, this program began to fail in a very unpredictable manner. Instead of getting a new image installed which unfortunately can take a lot of time here, I installed a very old version of the program that used simple MAPI and worked just fine with Outlook 97!. The very first time the program got invoked and went to send out about a dozen emails, up popped this dialog. Did I mention that this PC was running unattended Man was I pissed. Anyways, I reverted back to Noel's code and using it instead, does not cause that dialog to come up. If you are presently using something like simple MAPI, you should be able to convert to it easily.

Oki, have gotten around the warning dialogue using this class. But the fact that the button still not can be presses is bugging me. Must be a way to press it since there are comercial products out there that does just what I wanted to do, more ideas please

Symantec apparently has a nice library of controls. I've alway likes their UI. I personally
can't stand UI coding so I'd sure like to use their code
Sorry, what was your question again?

In VC++, for following program,
class A
{
int a;
char b;
};
void main()
{
A a;
cout<
|
|
|
|
|
because the members are alligned on the size of the bigger member...
|
|
|
|
|
In order to acheive 1Byte alignment,try the following :
#pragma pack (1)
class A
{
int a;
char b;
};
#pragma pack (1)

this shouldn't be done unless you are on a very specific requierement (and plateform).
if you have to save some memory from the object size, better rearrange the members order first.

Hi toxcct ,

It's correct , but from his question , i think that he ment that the data
should be 1Byte aligned.
toxcct wrote: if you have to save some memory from the object size, better rearrange the members order first.
It is not always possible (for example if you got an ICD of another
machine and you need to "Speek" with the same language of that machine -
you can't change the members order  ).

It is called padding - the size of the structure is padded with empty space to optimize its access. A 32-bit system moves data in 32-bit chunks faster than data that is not sized at 32-bits.
Note tha packing may also impact the size of the structure - structure members are normally aligned in order to optimize their access (non-aligned access is allowed x86 architecture, but it takes a performance hit). 32-bit values are aligned to start at a 32-bit boundary, 16-bit values are aligned to a 16-bit boundary, etc. by moving the start of the structure in memory so that it lies on its natural boundary (32-bit boundary, for example).
struct STest
{
DWORD m_dwValue;
char m_cValue;
};
struct STest2
{
DWORD m_dwValue;
char m_cValue;
int m_iValue;
};
struct STest3
{
DWORD m_dwValue;
short m_siValue;
char m_cValue;
};
The sizes of the structures (with default 32-bit padding) are 8, 12 and 8 bytes, respectively, and are layed out in memory as follows:
FF FF FF FF 61 <code>CC CC CC</code>
FF FF FF FF 61 <code>CC CC CC</code> 11 00 00 00
FF FF FF FF 12 34 7A <code>CC</code> Bolded bytes are the padding/packing bytes.
When laying out the order of members in a structure, if you place them so that they are more likely to fall on their natural alignment, you can reduce the footprint of the structure.
You may have to force the packing of a structure when sharing serialized (saved to some medium) data between two different applications/systems, like when sending data over a socket to a server - both systems have to agree on the packing/padding of the data in order to read it correctly.

Hello, I have a problem that I simply can't solve on my own.
Background:
I have a single document MFC application where the user may doubleclick on a piece of text and thereby call forth a dialog window for editing the text. That text is displayed in a Static text box. If I make a change to the text I can use Ctrl+Z or Ctrl+Y to Undo/Redo and that is great but some users do not know all short-commands so I also want to make an Undo button and a Redo button to do the exact same things. Outside the dialog in my application the accelerators Ctrl+Z and Ctrl+Y are tied to my own-defined Undo/Redo functions that are specific to my application so how do I find out what events the Ctrl+Z and Ctrl+Y accelerators in the dialog triggers?
Problem:
Since Ctrl+Z/Ctrl+Y works in my dialog although they are not defined in my IDR_MAINFRAME Accelerators they must obviously be connected to functions that are specific for performing Undo and Redo in a Dialog window. How do I connect those functions to two Undo Redo buttons as well?
Visual Studio version:
Microsoft Visual Studio 2003
|
|
|
|
|
The standard edit control has its undo/redo functionality built it, just as the Rich Edit control does - you do not really have to do anything to and you get it for free.
You can implement the button handlers so that they send EM_UNDO messages to the edit control. Lookup the EM_UNDO message for more details.
Peace!
