Except that you have to create all the edit boxes (in a for loop).

if you are using Visual Studio 2003, then follow these steps :-
Click On Project Menu Item then Click PROJECT_NAME properties. A Dialog Box will be popup, then choose Linker Tree Item, after Linker Tree Item get expanded choose General tree Link and in General properties, choose YES(/INCREMENTAL) combo option in Enable Incremental Linking link

No tooltips within message loop

Wim Engberts5-Feb-06 23:49

Hi,

I have a program to debug a proprietary mapping language. The window contains a CToolBar that will generate tooltips. When the program runs, it stops at each mapping command, waiting for the user to press all kinds of keys. During this, I have the messages processed using the following code:

while (m_bLoop)
{
WaitMessage ();
while (PeekMessage (&msg, NULL, 0, 0, PM_REMOVE))
{
if (!PreTranslateMessage (&msg))
{
TranslateMessage (&msg);
DispatchMessage (&msg);
}
}
}

During this message pump, everything works just fine (keys, menus, sizing or moving the window, etc), except that the tooltips on the toolbar don't show. When the program ends, and hence reverts to the standard message pump, the tooltips will show again.

Does anyone have an explanation for this?

Thanks in advance for any help

If you overrode PreTranslateMessage, did you call the base class PreTranslateMessage or not? Since it relies upon calling

AFX_MODULE_STATE* pModuleState = _AFX_CMDTARGET_GETSTATE();
if (pModuleState->m_pfnFilterToolTipMessage != NULL)
(*pModuleState->m_pfnFilterToolTipMessage)(pMsg, this);

to get the tooltips processed.

Thanks for the remark. I do indeed override the PreTranslateMessage, but I also do include a call to the base class version:

BOOL CView32Dlg::PreTranslateMessage(MSG* pMsg)
{
BOOL r = TRUE;

if ( m_hAccel == NULL
|| !TranslateAccelerator(this->m_hWnd, m_hAccel, pMsg))
r = CDialog::PreTranslateMessage(pMsg);

return r;
}

As a test, I have also already tried to only call the base class PreTranslateMessage (so ignoring the accelerators):

BOOL CView32Dlg::PreTranslateMessage(MSG* pMsg)
{
BOOL r = TRUE;

// if ( m_hAccel == NULL
// || !TranslateAccelerator(this->m_hWnd, m_hAccel, pMsg))
r = CDialog::PreTranslateMessage(pMsg);

return r;
}

This indeed resulted in my accelerators not functioning, but I still did not get any tooltips (of course, only until my mainloop ended and the program falls back into the Microsoft message pump, wherever that may be)

Thanks

One idea, then might be to call this from your own PreTranslateMessage
void CWnd::FilterToolTipMessage(MSG* pMsg)
and if the tooltips don't appear, then maybe they are disabled.

You can try calling
BOOL CWnd::EnableToolTips(BOOL bEnable)
to make sure tooltps are activated for your window.

Then don't use the modeNoTruncate flag. Use only the modeCreate flag.

Hi I know my answer is a stupid one... but still

You want to write again from beginning. its equal to close the previous handle. Open is any other mode that delete the file and create it. then close again.( this is equal to close the handle and delete the file). then open in notruncate mode again.

souds funny I know. I will try to find out better options...

Re: Writting a data insame file again

Wim Engberts5-Feb-06 23:53

Hi,

Another option would be to set the filecursor back to the beginning using CFile::SeekToBegin (); and then emptying the file by CFile::SetLength (0);

Regards
