So why don't you remove the spaces prior to adding the items to the list control?

void CMyList::OnOK()
{
UpdateData();
m_list2.RedrawItems(0,m_list2.GetItemCount());
CString sName = _T("Name");
m_name.GetWindowText(sName);
LVFINDINFO stInfo = {0};
stInfo.flags = LVFI_PARTIAL;
stInfo.psz = sName;
int nItem = m_list2.FindItem( &stInfo );
if( nItem != -1 )
{
// the item is in the list control
CString sSecondColumnText = m_list2.GetItemText( nItem, 1 );
// set the text to the second edit box
m_rezult.SetWindowText( sSecondColumnText );
}
}
Only this code works !

CListCtrl::GetItemText has two items or four items index of item(one parameter) and nSubItem(two parameter)
now if you used this function in the loop you can find your item in another colunms and need to check this string with your string
(like InsertColumn or InsertItem that you can see two parameter)

you can give an example ? please !!!!!!!

if you dont need to this item you can delete it from listbox
|
|
|
|

I Just Need to make it Disable and After that I will Enable it , This is my need
|
|

It seems the CListBox class does not support "enabled/disabled" state of items.
I think instead of CListBox you have to try another class -- CCheckListBox -- and deal with the state of checkboxes.
I hope it helps.

Hi!!
I have a doubt regarding SendMessage() function. According to MSDN SendMessage syntax is as follow;
LRESULT SendMessage(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam
);
But I am not getting what wparam and lparam are erally used for. Its given in MSDN that they are jst for additional information about the msg.
Thx,
|

SendMessage(..) is mainly for user messages.
Say in one class you have two numbers and you have addition method in another class, now you can use the SendMessage as
SendMessage(AddtionMethodHWND, User_Msg, 5, 10)
you can send a structure or class as the Param values, but those have to be as pointers and the destination methos have to take care of deleting the allocated memory
PostMessage(..) also act as SendMessage(..),
PostMessage just send the message and continue executing the next line but SendMessage will wait untill the methos returns

Hi!
Thx for the reply.
Actually I am facing a problem where I am trying to port a VC6 code to VC8. In My VC6 code I was passing an iterator to the SendMessage just by typecasting it to WPARAM. But VC8 compiler is allowing to do this and giving me error saying..
error C2440: 'type cast' : cannot convert from 'std::_Vector_iterator<_Ty,_Alloc>' to 'WPARAM'<br />
with<br />
[<br />
_Ty=KPUnprotectedFileCmd_s,<br />
_Alloc=std::allocator<KPUnprotectedFileCmd_s><br />
]<br />
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
can u suggest me solution tio this peoblem.
Thx again!

Hi...
Windows have message driven architecture basically. Messages are nothing but events (in VB). For every action a window will get a message like, WM_LBUTTONDOWN, WM_LBUTTONUP, WM_MOUSEMOVE, WM_MOUSEWHEEL etc., The above said messages are mouse click events that will be sent to a window if user clicks on it. Say, if a user clicks on a window... that window will get WM_LBUTTONDOWN message first and WM_LBUTTONUP when he release it. With this message additional information like X,Y positions where the user clicked also will be sent to that window.
Ok... now come to SendMessage() function. SendMessage function is having as u said four parameters,
LRESULT SendMessage(HWND hWnd,UINT Msg,WPARAM wParam, LPARAM lParam);
here hWnd is the handle to the window where you want to send the message
Msg is the Message as above said WM_LBUTTONDOWN or WM_LBUTTONUP (see msdn for all messages starting with WM_XXXXXXX)
wParam additional information
lParam additional information
for example, let us send a message to a window like user ctrl+clicks on it...
::SendMessage(hWnd,WM_LBUTTONDOWN,MK_CONTROL,MAKELPARAM(x,y));
::SendMessage(hWnd,WM_LBUTTONUP,MK_CONTROL,MAKELPARAM(x,y));
wParam and lParam will vary depends on the message you send. For WM_CLOSE, no need for wParam and lParam, so ::SendMessage(hWnd,WM_CLOSE,0,0); will close the window.
As our Friend Parthi said, difference between SendMessage and PostMessage is, SendMessage will send message and wait till the window process the message. PostMessage will post the message in the message queue and wont wait anymore.
I think the reply is pretty long, but clear enough. 
with regards,

hi!!
Iterator has a member called _MyPtr. Can I use that to get a pointer and then convert it to wparam??
thx
|
|

|

What iterator that was.. I mean map, list, vector..
anyway i hope the below approach will help you and i sorry 4 the delay..
Allocate memory of your type using new and copy the content from the iterator to the allocated memory and typecaste it...
say, the iterator has string valur then..
char *pStr = new char[..];
strcpy(pStr, (*it).c_str());
SendMessage(hWnd, USER_MSG, NULL, (LPARAM)(LPVOID)pStr);
the pStr memory should be freed in the handler of the message
