if (and only if) you have this requirement because of a bad designed function prototype (and you cannot change it, e.g. you have a third party DLL), i.e. a function that in fact doesn't change input buffer but accepts char * as argument, then you can simply cast the pointer.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Use const_cast<char*> (variable).

How could he know? Without seeing his problem clearly?

HI...
you using unicode or muli-byte characters??
Best Regards
|
|
|
|

If u have compiled your program with UNICODE and _UNICODE defined, then LPTSTR will automatically become LPWSTR (Long pointer to a wide string) u cant assign this to char* but u can assign this to a variable of type wchar_t*.
after using wchar_t* use swprintf() to get proper output.

Did you read his message ? He was talking about LPCSTR and not LPTSTR.

ohh sorry then If you use T2A macro, it will work in UNICODE and MBCS.
please go through T2A macro
|
|
|
|
|
Why would it be usefull to use the T2A macro ? A LPCSTR is a const char*.
I think you should read some documentation about the different string types to better understand the different namings.

|
|
|
|
correct
then why she wants to do that?
|
|
|
|
|
Probably because the compiler complains about the constness.

For button bitmaps in an MFC toolbar, you can use a masked
imagelist to hold the bitmaps.
m_ToolBarImageList.Create(IDB_BITMAP1, 16, 1, RGB(0x00,0xFF,0x00));
...
m_ToolBar.GetToolBarCtrl().SetImageList(&m_ToolBarImageList);

I wrote a class CCamCtrl. I use a Custom message WM_CAPTURE_IMAGE and used message mapping. A dll is to post message. I think dll does not post messsage, sothat OnCaptureData(WPARAM wParam, LPARAM lParam ) event can't be called.
Are there any problem in my code or in dll.
here i mention that dll works well for dialog based application.
Can anyone help me?
Thanks in Advance
Mazhar
header file
class CCamCtrl : public COleControl
{
//some code
///
///
// Message maps
//{{AFX_MSG(CCamCtrl)
afx_msg void OnCaptureData(WPARAM wParam, LPARAM lParam );
afx_msg void OnShowWindow(BOOL bShow, UINT nStatus);
afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
afx_msg void OnTimer(UINT nIDEvent);
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
in cpp i wrote
BEGIN_MESSAGE_MAP(CCamCtrl, COleControl)
//{{AFX_MSG_MAP(CCamCtrl)
ON_MESSAGE(WM_CAPTURE_IMAGE,OnCaptureData)
ON_WM_SHOWWINDOW()
ON_WM_LBUTTONDOWN()
ON_WM_TIMER()
//}}AFX_MSG_MAP
ON_MESSAGE(OCM_COMMAND, OnOcmCommand)
ON_OLEVERB(AFX_IDS_VERB_PROPERTIES, OnProperties)
END_MESSAGE_MAP()

Hi all,
I would like to know in general what causes a large amount of virtual memory to be used when creating an application. I.E What within the application causes a large amount of virtual memory to be used.
Thanks in advance

If you create a lot of classes with'in huge memory allocation. And you don't release it.
Or if bitmaps are loaded.
I sawed already that the visual studio debugger don't frees the memory at realtime.
If you create a view, close it, create, close, ...
then you get not the initial memory size of your application
