Dialog tab order

Is it possible to use the tab order set for edit controls in the dialog editor in the program? Is it possible to access an edit box via its tab order?

I can access by the control ID like this:
CWnd* pt;
pt = AfxGetApp()->m_pMainWnd->GetDlgItem(IDC_EDIT1); <-----uses IDC_EDIT1
pt->SetWindowText("AAAAA");

Or I can access a different edit box by an offset to the first ID Like this:
pt = AfxGetApp()->m_pMainWnd->GetDlgItem(IDC_EDIT1 + 8); <----uses IDC_EDIT1 + 8

Or I can set up the IDs in an array, and access like this:
pt = AfxGetApp()->m_pMainWnd->GetDlgItem(IDArray[5]); <----uses ID stored in array

So, this leads me to ask if there is some way to use the tab order defined in the dialog editor to do something similar.

Thanks

You can iterate through the controls in their tab order with GetNextDlgTabItem()

The tab order determines what order the controls are placed on the dialog window
by changing the order of the control statements in the dialog resource.

I suppose you could enumerate all the child windows of the dialog with GetTopWindow() and
GetNextWindow() (which would iterate through the controls in reverse tab order) or use
EnumChildWindows(). For each child window, check its class with GetClassName() to see if it's an
edit control. If it's an edit control then process it accodingly.

This seems like a lot of work considering you have full control over which controls are in
the dialog and what all of their IDs are, even if you add or remove controls at runtime. Unless
controls are being added/removed by another process...

If I knew what you are trying to do I could maybe give you a more specific code example Smile | :)

How do I change icon and small icon for a windows class

Hi all, I was trying to change the application icon through the windows class by changing the icon macros loaded into windows class as shown below, but no matter what icon macro I choose the icon displayed is the application icon from IDI_APPLICATION macro.

<br />
	windowClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);	//default Icon<br />
        ...<br />
        ...<br />
	windowClass.hIconSm = LoadIcon(NULL, IDI_WINLOGO);<br />

Could please tell how to change the icons by icon macros. Any help would be greatly appriciated.

Thanks

if you run this code wcex.hIconSm= LoadIcon(wcex.hInstance, (LPCTSTR)IDI_SMALL);what happens?
From the MSDN
HICON LoadIcon(HINSTANCE hInstance,LPCTSTR lpIconName);

hInstance
[in] Handle to an instance of the module whose executable file contains the icon to be loaded. This parameter must be NULL when a standard icon is being loaded

Hi WhiteSky,

I have just tried the code as you suggested

<br />
	windowClass.cbSize = sizeof(WNDCLASSEX);<br />
	windowClass.style = CS_HREDRAW | CS_VREDRAW;<br />
	windowClass.lpfnWndProc = WndProc;<br />
	windowClass.cbClsExtra = 0;<br />
	windowClass.cbWndExtra = 0;<br />
	windowClass.hInstance = hInstance;<br />
	windowClass.hIcon = LoadIcon(windowClass.hInstance, (LPCTSTR)IDI_WINLOGO);	//default Icon<br />
	windowClass.hCursor = LoadCursor(NULL, IDC_ARROW);		//default arrow cursor<br />
	windowClass.hbrBackground = NULL;						//don't need background<br />
	windowClass.lpszMenuName = NULL;						// no menu<br />
	windowClass.lpszClassName = "AeroClass";<br />
	windowClass.hIconSm = LoadIcon(windowClass.hInstance, (LPCTSTR)IDI_WINLOGO);<br />

but still the default application icon is displayed. I would like to use standard icon Windows logo to be displayed on my application window, so I was using NULL in my code in the previous posting.

All I want to do is change the icon on my application window to Windows logo using standard icon macro IDI_WINLOGO.

Any help would be greatly appriciated.
Thanks

open the resource header file, find the definition for the icons. Give the icon you want the smaller number. The default Icon for an exe is the first icon found (the one with the smallest number).

You can override PreCreateWindow() to use your custom window class instead of the default...

This example assumes szMyRegisteredWindowClass points to the class name associated with your
"windowClass"

BOOL MyWindowClass::PreCreateWindow(CREATESTRUCT& cs)
{
	// Let base class fill in the default CREATESTRUCT

	if( !CBaseWndClass::PreCreateWindow(cs) )
		return FALSE;

	// Now alter CREATESTRUCT with our custom settings

	cs.lpszClass = szMyRegisteredWindowClass;
	cs.style = <possible override default window style here>;
	cs.dwExStyle = <possible override default extended window style here>;

	return TRUE;
}

Simple MAPI Error !!!

Hello,

I want to send mails(with attachments) from my MDI based application.

I got lot of articles from CodeProject regarding MAPI. I choose "David Brooks" article which uses simple MAPI.

Here is my code ...

class CSendFileTo
{

protected:

HWND m_hWndParnt; // Window handle
enum Error {SUCCESS, NO_ATTACHMENT=0x1001, NOT_A_WINDOW, LIB_LOAD_FAILED, GETPROC_FAILED};

// MAPI related data members
HINSTANCE hMAPI;

public:

CSendFileTo();
virtual ~CSendFileTo();

CSendFileTo(HWND hWnd)
{
m_hWndParnt = hWnd;
}

unsigned int SendMail(CString const &strAttachmentFileName,CString const &strSubject=_T(""),CString const &strToAddr=_T(""),CString const &strToName=_T(""),CString const &strBody=_T(""))
{
if (strAttachmentFileName.IsEmpty())
return NO_ATTACHMENT;

if (!m_hWndParnt || !::IsWindow(m_hWndParnt))
return NOT_A_WINDOW;

hMAPI = ::LoadLibraryA(_T("MAPI32.DLL"));
if (!hMAPI)
return LIB_LOAD_FAILED;

ULONG (PASCAL *SendMail)(ULONG, HWND, MapiMessage*, FLAGS, ULONG);
(FARPROC&)SendMail = GetProcAddress(hMAPI, _T("MAPISendMail"));

if (!SendMail)
{
::FreeLibrary(hMAPI);
return GETPROC_FAILED;
}

TCHAR szFileName[_MAX_PATH];
TCHAR szPath[_MAX_PATH];
TCHAR szSubject[_MAX_PATH];
TCHAR szBody[_MAX_PATH];
TCHAR szToName[_MAX_PATH];
TCHAR szToAddr[_MAX_PATH];

strcpy(szFileName, (LPCTSTR)strAttachmentFileName);
strcpy(szPath, (LPCTSTR)strAttachmentFileName);
strcpy(szSubject, (LPCTSTR)strSubject);
strcpy(szBody, (LPCTSTR)strBody);
strcpy(szToAddr, (LPCTSTR)strToAddr);
strcpy(szToName, (LPCTSTR)strToName);

// Setting Attachment Info
MapiFileDesc fileDesc;
ZeroMemory(&fileDesc, sizeof(fileDesc));
fileDesc.nPosition = (ULONG)-1;
fileDesc.lpszPathName = szPath;
fileDesc.lpszFileName = PathFindFileName(szFileName); // Remove the path

// Setting Recepient Info
MapiRecipDesc recpnts;
ZeroMemory(&recpnts, sizeof(recpnts));
recpnts.ulReserved =0;

if (nError != SUCCESS_SUCCESS && nError != MAPI_USER_ABORT && nError != MAPI_E_LOGIN_FAILURE)
return nError;

::FreeLibrary(hMAPI); // Freeing the DLL handle

return SUCCESS;
}

void ShowError(UINT errCod)
{
if (errCod)
{
CString str;
str.Format("Error: %X", errCod);
AfxMessageBox(str);
}
}

};

// Invoking Send Mail function
void CDefectLinkerDlg::OnButtonSend()
{

CSendFileTo sendTo(this->m_hWnd);
int nError = sendTo.SendMail(m_attachments,strSubject,strURL,strName,strBody);

if(nError != 0)
{
sendTo.ShowError(nError);
}
}

I can run this application. I got the MS Outlook 2000 window and it shows my mail with attachment.

But when I press the "Send" button in Outlook , both my application and the MS
Outlook program is closed.

But that mail is located in my Outbox. But Outlook cannot deliver that meesage ..,I got "Mail delivery failure" error...!

What will be the problem ?

Pls help me...

Thanks in advance

7-Oct-06 2:22

Hello everyone,

I just created a program that use a WIN32 internet APIs, so i found the useful library called WININET.lib and i decided to add some functionalities like changing internet setting and so on, the problem is when i tried to change the username/password using InternetSetOption then calling InternetAttemptConnect function nothing happens (the settings rest in default stat)another questions is how do i change username and password even when the first parameter of InternetSetOption is NULL for example :
InternetSetOption(NULL,INTERNET_OPTION_USERNAME,
lpszUser, strlen(lpszUser)+1);

(change the defaut setting of dial up connection)
I'll be wondered if someone could help or just to post a tutorial for how to use InternetSetOption function (its not enough documented in MSDN Frown | :(

for me)
Thank you
