Another option is to use CRichEditCtrl::SetSel[^] to set the 'carret' position (in fact, the text which is selecetd in the control, if nStartChar is equal to nEndChar, then, you specify a carret position). You can then use CRichEditCtrl::ReplaceSel[^] to replace the text which is selected (ans thus, insert text also).

yes this is a good approach
actually i am doing multilevel undo/redo for richedit ctrl(CRichEditCtrl)
and when i searched on codeproject i didn't got any undo redo code for CRichEditCtrl.
so currently i am making dynamic stack in which i am storing the caret position and the character.in OnChar handler.
and i am thinking that when user will say undo i will pop one frame and will insert that character in the rich edit control at that position.
Is it a good approach??
and is there no other API that will just take the character and caret position o insert the character??
Thanks and regards

CString m_str;
m_richedit.GetWindowText(m_str);
m_str.Insert( Index, "string to be inserted" );
m_richedit.SetWindowText (m_str);

You can read your pictrue(bmp) with CImage class and use from save

I have to launch from my code some third party program that may result in system restart. In case that the system restart is not performed immediately (for example with <shutdown t="" 30="" s="">), I need my program to terminate and prevent the user from cotinue running my program in the time remaining till shutdown.
Question: How can I detect that <system shutdown=""> was issued?
(I tried to start some process from my code an get the error code informing that the system shutdown is pending, but this solution is buggy, since I do not know which process can i start on user's machine and in case that there is no system shutdown pending it looks ugly - console opens, etc.)

All top-level windows receive a WM_QUERYENDSESSION message when a logoff/shutdown/restart is initiated. If no app cancels the action, windows get WM_ENDSESSION to indicate that the system is shutting down.

Thanks,
but the problem is I can not poll in a loop.
I need to run a single query when I got the control back from the T.P. program I'm running from my code.
Any ideas?
|
|
|
|
|
You don't poll to get those notifications, they arrive in the message queue like any other messages.
|
|
|
|
|
The problem is that I can't listen to the message pipe. I need a single method cal to guery OS "is there a shutdown pending or not". That's the situation. Any ideas?

u are allocating undersize memory to buffer
|
|
|
|
|
Not necessarily...
The OP has code which is trying to access memory that isn't allocated at all, or is trying to write to memory that is read-only - note that this is not hardware related, it's a memory management thing.
Things to do:
use the 'debug' command to run the app and find out where the bad code is.
look for pointers that are being used, but not being initialised/set correctly.
For example,
LPTSTR text = NULL;
or just
LPTSTR text;
The compiler won't flag the first case with 'used but not initialised', but it would generate an AV error (deliberately).

Can you give some more details on your problem?
Somethings seem HARD to do, until we know how to do them.

Could you be more specific
|
|
|
|

// Field/Param Data
// field data members
long* m_rgID;
LPSTR m_rgName;
// pointers for the lengths
// of the field data
long* m_rgIDLengths;
long* m_rgNameLengths;
// input parameter data member
CString m_strNameParam;
void MultiRowSet::DoBulkFieldExchange( CFieldExchange* pFX )
{
// call the Bulk RFX functions
// for field data members
pFX->SetFieldType( CFieldExchange::outputColumn );
RFX_Long_Bulk( pFX, _T( "[colRecID]" ),
&m_rgID, &m_rgIDLengths );
RFX_Text_Bulk( pFX, _T( "[colName]" ),
&m_rgName, &m_rgNameLengths, 30 );
// call the RFX functions for
// for parameter data members
pFX->SetFieldType( CFieldExchange::inputParam );
RFX_Text( pFX, "NameParam", m_strNameParam );
}
And i want to add CStrings because my field data are :
CString m_listare;
CString m_carte;
how to do this with CStrings ?
RFX_Long_Bulk( pFX, _T( "[colRecID]" ),
&m_rgID, &m_rgIDLengths );
RFX_Text_Bulk( pFX, _T( "[colName]" ),
&m_rgName, &m_rgNameLengths, 30 );
