No, It´s a different question, the other one is solved. That´s a completely different part of the app.

There are a few questions that you need to answer before you get the answer here Roll eyes | :rolleyes:

1) How are you creating the dialog (Modal/Modeless)?
2) Are you explicitly trying to set the focus on the Edit Control. If yes,
Do remember one thing - OnInitDialog returns TRUE to indicate that the focus should be set to the first control in the dialog box. So if you are setting the focus explicitly to some other control return FALSE from OnInitDialog.

Somethings seem HARD to do, until we know how to do them.

Ok, lets see.
De dialog is created as Modal with DoModal();
I try to set the focus with this line:

SendDlgItemMessage(IDC_TXTISSI,WM_SETFOCUS);
//Where IDC_TXTISSI is the ID of the EditBox I want to write on

I changed the return value at the OnInitDialog. It doesn´t work. I still have to press TAB key and make a round if I want to write... Could it be some property of the EditBox? I have compared with all the others and have the same properties...

Confused | :confused:

Whether TRUE or FALSE is returned will have no impact on what garfield185 is seeing. Once a control is selected via the mouse, anything that happened in OnInitDialog() is gone.

I don´t know which part of the code is making this... Confused | :confused:

Anyway, if you see the proyect I uploaded in the previous post, it has only an Edit Box, and it´s impossible to write on it until you reach the edit control with the tab key.

Why is that happening?

PreTranslateMessage

garfield18528-May-07 22:07

28-May-07 22:07

Hi members!

I´m using the event PreTranslateMessage to catch the Return Key when it´s pressed in a EditBox.
When the user presses VKRETURN...

BOOL CConfLlamDlg::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->wParam == VK_RETURN) // if enter key pressed return true
{
MessageBox("Error");
}
return CDialog::PreTranslateMessage(pMsg);
}

If the user accepts that message Box clicking with the mouse there is no problem, but when I accept the message box pressing Enter key, it generates another VKRETURN message that calls again the PreTranslateMessageFunction.

Can someone help me?

Thanks everybody!!

You're not checking the message type!

if(pMsg->message==WM_KEYDOWN && pMsg->wParam==VK_RETURN)

I always say the same:

I love using this forum and I love you guys!! You are my salvation!! I´m about to finish my proyect and I have no time left!

I really thank you a lot, Steve.

In addition to what Stephen said, check whether the message is for edit control

if(pMsg->wParam == VK_RETURN && pMsg->message == WM_KEYDOWN && pMsg->hwnd == m_Edit.m_hWnd )

zlib can do this for you.
Its free and readily available for inclusion in your project.

Failure is not an option - it's built right in.

Get dll name

28-May-07 21:36

Hi all,

I have 'A.exe' running. It loads and uses 'B.dll'.
How to get the name of the dll i.e 'B.dll'?
If i use GetModuleFileName() in 'B.dll' file, it returns 'A.exe' and not 'B.dll'.
I have to write the code in 'B.dll'.

Thank you

Naveen28-May-07 21:41

28-May-07 21:41

use this code in the b.dll

TCHAR tczFileName[ MAX_FILE_LENGTH ];<br />
MEMORY_BASIC_INFORMATION stMemoryInfo; <br />
static int nAddress;<br />
HMODULE hModule = 0;<br />
// Get the information about the virtual address space of the calling process<br />
if( VirtualQuery( &nAddress, &stMemoryInfo, sizeof( stMemoryInfo ))<br />
                                                            != 0 )<br />
{            <br />
    hModule = reinterpret_cast<HMODULE>( <br />
                                    stMemoryInfo.AllocationBase);<br />
}<br />
// Get the exe's or ddl's file name<br />
DWORD dwFileNameLength = GetModuleFileName( hModule,tczFileName,<br />
                                          MAX_FILE_LENGTH );

Call GetModuleFileName() like this:

TCHAR szPath[1024] = { _T('\0') };
GetModuleFileName((HMODULE)AfxGetInstanceHandle(), szPath, sizeof(szPath)/sizeof(TCHAR)-1);

For non-MFC DLL's, you can just use the hInstance that was passed to the DllMain() function.

Best wishes,
