Why don't you simply delete the contents of the iterator without the cast ? You don't need to cast it.

Because the destructors of the objects allocated in the arrays (eg CVersion) would not be called...

Yes they would. The content of your iterator is not a void pointer, it is a template, so the compiler knows which object it needs to destroy.

I do not know why - if it's a problem in the code tag or (and that would be embarrassing) I cannot do a copy and paste but
this is what I meant

<br />
typedef std::vector < void * > ARRAY_PTR;<br />

so yes the iterator content is void *

I see. But I still don't understand what you are trying to do.

You posted this code:

ClearPtrArray< askia_wave::CVersion > (m_rgVersions);
ClearPtrArray(m_rgQuestionClasses);
ClearPtrArray(m_rgLanguages);
ClearPtrArray(m_rgModalities);
ClearPtrArray< askia_wave::CQuestion >(m_rgQuestions);
ClearPtrArray(m_rgWaves);

Can you show the definition of m_rgVersions, m_rgQuestionClasses, m_rgLanguages, ... ?

I suppose they are all of type std::vector<void*> (I just guess, because otherwise the code won't compile I think).

But then my question: why don't you use vector in the standard way ? So, store the pointers to your class and not a simple void pointer ?

you are right about the declaration

<br />
		ARRAY_PTR m_rgWaves;<br />
		ARRAY_PTR m_rgQuestions;<br />
		ARRAY_PTR m_rgQuestionClasses;<br />
		ARRAY_PTR m_rgModalities;<br />
		ARRAY_PTR m_rgLanguages;<br />
		ARRAY_PTR m_rgVersions;<br />

yes you are right, I could use a vector like this vector < CQuestion * > m_rgQuestions but the idea was to have something like the MFC CObArray. Oh and the code is shared ( I did not write it) ... and it should work so it is a bit of a pain to rewrite a lot of code because it is used in a VC 6.0 project...

Hi,

<br />
CreateFile( "FullFilePath", GENERIC_WRITE, FILE_SHARE_READ, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);<br />

e.g. with FullFilePath = "C:\\MyDir\\MyApp\\debug\\filename.ini"

or get the directory with: GetCurrentDirectory(...)
or otherwise with: GetModuleFileName(...) + _splitpath(...)

In addition to what the others have indicated about creating the file. If you want to just create the file while in a debug build use

#ifdef DEBUG
...
#endif

I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

Ignore mouse event

Haribaskar4-Dec-06 0:20

Hi,

I have a problem with regards to ignoring mouse events.

Here is my requirement :

I have an application where some dialogs need to ignore mouse message and some dialogs should not

Solutions tried :

1. I have tried installing a mouse hook. But, in the mouse processor I need to always check the window pointer and its parents to determine whether I need to ignore and all call the next hook

Is there any member funciton/message handler of CDialog class by which we can ignore all mouse events/messages for that particular dialog ?

Appreciate any help that I can get

Regards,
Hari

I have a class dervied from CDialog and wants to ignore all the mouse message coming to the windows. I have used a solution

Re: Ignore mouse event

BadJerry4-Dec-06 0:36

All I can think of is PreTanslateMessage... Something like this:

<br />
BOOL CCrossTabQuestionPage::PreTranslateMessage(MSG* pMsg) <br />
{<br />
	switch ( pMsg->message )<br />
	{<br />
		case WM_LBUTTONDOWN:<br />
		case WM_LBUTTONUP:<br />
		// .. and all other mouse messages<br />
			return true;<br />
	}<br />
	<br />
	return CDialog::PreTranslateMessage(pMsg);<br />
}<br />
<br />

This is likely to work but I have not tested it!

Global Hook or local Hook!

naah.. you have to check every dialog or hook only particular dialog!

Hi,

Can someone direct me (maybe a link or tutorial) on how to write a program to print to a Dot-Matrix printer. I need total control of which characters to print and will also need to send printer commands to the printer, i.e to move the head on vertical tab etc. (I already have the printer commands)

Any help would be appreciated.
Thanks in advance

Pieter

If you are using fprintf(), then open "LPT1:" as the file stream.
