Just like you would any other type:

void AFXAPI DDX_Text( CDataExchange* pDX, int nIDC, int& value );

Thanks David

But if I try to exchange data between an IDC control and a structure member that is defined as boolean - The compiler poses an error.

What I'm doing right now is to store the value of this struct member (boolean)in an int, exchange the data with int and store this int back in struct member (boolean)- Any better way to do this - ?

You can always write your own custom DDX_ routine. They are not sacrosanct, after all.

Just use the one that does ints as a template and copy the code to your program.
Then modify it to accept the BOOL and do necessary conversions.

Any sufficiently gross incompetence is nearly indistinguishable from malice.

Do u mean i use AfxGetMainWnd()
& then use PostMessage to handling that with
CMainFrame class?

You indicated that you wanted to "call CMainFrame's function from my CDocument class." AfxGetMainWnd() is used to get a pointer to the frame window object. With that, you can call whatever function you need.

But i can not access function that i declare in CMainFrame object!
for example i wrote CreatePane function in CMainFrame object.
i wanna call this function
from CMyDocument ! i use AfxGetMainWnd but m_pMainWnd can not access
CreatePane or CreatePane did not declare in FrameWnd object!

best Regards.

Why not?

Probably because you forgot to cast the return value from AfxGetMainWnd().

i need if is found , or not !
if is found SetWindowText the string from another table and if is not AfxMessageBox ("Not Found in your Database !")

this is my code :

void CNcontabile::OnChangeGestiuneadb()
{

CString strCourseID;

CWaitCursor wait; // Display a wait cursor

CDatabase_Bun *pBun;

pBun = new CDatabase_Bun;
// Set the filter
pBun->m_strFilter = "um = '" + strCourseID +"'";

if(pBun->Open());
return;

if (pBun->IsOpen())
{

while(!pBun->IsEOF())

{

m_gestiuneaDb.GetWindowText(strCourseID);

strCourseID.TrimLeft();
strCourseID.TrimRight();
m_gestiuneaDb.SetWindowText(strCourseID);

if(strCourseID == pBun->m_um )
{
m_dengestiuneDb.SetWindowText("GGGGGGG");

}

}

}

pBun->Close();
delete pBun;
}

is not working because i have a filter and is no match !
my second problem is how to trim the spaces ? (CEdit & the CDatabase spaces ) ????????????

Since strCourseID is empty, this'll never work.

Why are you calling these in a loop? Call them once outside of the loop. Roll eyes | :rolleyes:

Bravoone_2006 wrote:
if(strCourseID == pBun->m_um )

I don't suppose you've bothered to set a breakpoint on this statement to see the different values of strCourseID (which we already know is empty) and pBun->m_um. That's the main reason why you can't see the problem.

Bravoone_2006 wrote:

Actually it is working. It's doing exactly what you told it to do - find records where pBun->m_um is equal to empty. Hint: no records match this criteria.

   I do not think that you can - I believe that BHOs and similar ADD-ins are supported by the "framework" provided by Internet Explorer, not by the WebBrowser control proper.

   This is actually one of the dangers of hosting the WebBrowser control. If you allow it to be used for general browsing by a user (allowing dropped links, not properly disable the context menu, handing the new window event, etc.), the user is browsing in a "less secure" environment than Internet Explorer offers, and this may lead to problems (like popup-mismanagement).

   Peace!

How to get icon regions from list view?

Amar Sutar5-Oct-06 1:56

Hi all,

I'm trying to get a region containing the icon from the listview. I tried using "ListView_GetItemRect(hSysListView32Wnd, i, &rect, LVIR_ICONS)" on
SysListView32, but it returns a region that is too big (contains a
rectangular block surrounding the icon).

Thanks in advance.

Amar. Smile | :)
