I have to write a program which shows a dialog when click on a button. After that, when click outside this dialog, it will be closed.
I've tried to use OnKillFocus function to check whether this dialog should be closed or not but it doesn't work.
Could u suggest me another solution to to this task?
Thanks in advance.

OnActivate? (assuming you use MFC)

I just tested this, OnActivate won't work for you. Since it's a modal dialog (which I assume it is) it won't receive OnActivate messages when you click outside the dialog. Similarly, you won't get any WM_LBUTTONDOWN or the likes when the user clicks outside your dialog. Instead, you must handle the WM_NCACTIVATE message:
In your dialog class header, put
<br />
afx_msg BOOL OnNcActivate(BOOL bActive);<br />
and put
<br />
ON_WM_NCACTIVATE()<br />
in the dialog class' message map.
in CYourDialog::OnNcActivate handle the case bActive==FALSE, this is when the user clicks outside the client area. Dismiss your dialog in whatever way is appropriate.
Cheers
Steen.

What does not work ? You do not catch the WM_KILLFOCUS message, or does the message not get send when you click outside the dialog ?
Three possibilities here (from the best to the least good, IMO):
1- Catch the WM_ACTIVATE message( MFC using afx_msg void OnActivate( UINT nState, CWnd* pWndOther, BOOL bMinimized ); and WA_INACTIVE as nState). In the message handler, dismiss your dialog.
2- Catch WM_KILLFOCUS, i still do not understand why this should not work
3- Handle WM_LBUTTONDOWN and WM_RBUTTONDOWN, check if the clicked position is inside the area of your dialog, if not, dismiss the dialog.
Hope this helps

This program I have to write is very similar to the Undo button in MS Visual C++ 6.0. When click on a button, a new dialog which have a listbox within it appears. We can choose item in listbox. When we click outside the dialog, it will be closed.
I use Create()& SetWindowPos functions to put the new dialog at the bottom of this button.
Firstly, I've tried to use OnKillFocus to check when the dialog lost focus but I always get WM_KILLFOCUS message immediately after SetWindowPos function. So the dialog disappear immediately after appear.
Second, I've tried to catch WM_ACTIVATE message but I don't know how to check WA_INACTIVE or WA_ACTIVE in the WM_ACTIVATE message. Do I have to override OnActivate function to handle WM_ACTIVATE message.
Could u tell me more detail?
Many thanks for your help. It's very precious.

Ok, this explains why OnKillFocus is not our solution here.

I still do not know if you are using MFC, but I will assume it. If not, post back and i'll give you the plain Win32 code.
So override the WM_ACTIVATE message (I guess you know how to do, if not : Right-click on your dlg class in the class borwser, [Add Windows MEssage Handler], Set [Filter for messages available to class] (on the bottom right) combo box on [Window], Select WM_ACTIVATE in the left listctrl and Click Add Handler button).
Then
void CYourDlg::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimized)
{
if ((WM_INACTIVE == nState ) && (pWndOther == FromHandle(m_hWnd))
{
}
else
{
CDialog::OnActivate(nState, pWndOther, bMinimized);
}
}

Your question is a little short on specifics, if you are using MFC then you can use the CFile class to write output to a text-file.

What kind of database? SQL? Access? Oracle? MySql?

i am using the Oracle database. i need to write the out put in oracle database

that's very easy when you know how to use the standard library... (i consider you're using pure standard C++)
ofstream MyFile("C:\\myDir\\myFile.txt");
MyFile << "Hello world !!!";
MyFile.close();

ok, i already provided you a sample but if you don't know where to start, do this :
#include <iostream>
void main(void) {
std::ofstream MyFile("C:\\myDir\\myFile.txt");
MyFile << "Hello world !!!" << '\n';
int i = 5+4;
MyFile << "i = " << i << endl;
MyFile.close();
}

I am working on a dialog based application where there are so many edit boxes.Now my requirement is that when the focus is in the first edit box & when i press the down arrow button,the focus(cursor) should shift to the next edit box(The tab order is already set in such a way that the focus goes to all the edit boxes one by one)..I had used the PreTranslateMessage() where i handled the VK_DOWN..Now here i have to write code for the shifting of cursor from one edit box to another edit box using SetWindowPos().I am not succeeded in completing this..So anyone plz help me!!

Why SetWindowPos ? You do not want to move the edit box, only the focus, don'T you ?
harish174 wrote: should shift to the next edit box
Two possibilities here :
- the edit boxes are made at runtime, so you must have a pointer on them, so you may use:
pEditCtrl->SetFocus();
- the edit boxes all have ids.
GetDlgItem(IDC_NEXTEDITBOX)->SetFocus();

You could also use GetNextDlgTabItem, this would mean that if you would change the tab order later using the resource editor, you wouldn't have to change the code as well.

If you are working on a dialog box try using...
NextDlgCtrl()
This moves the focus easily to next item in the dialog box.

Hi,
I am trying to extract data from word document to an edit box or notepad. I tried doing it usingIDispatch interfaces. i used other methods also. But the main problem is that i get certain meaningless characters in edit box after extraction.Perhaps this is due to the formatting characters in doc format. How can i get data from doc to notepad?
I am using VC++ 6.0.
Thanks in anticipation,
Ankush Mehta

If you are talking about small squares, maybe you should replace all "\n\r" by "\r\n" in the strings you are exporting.
