CMFCRibbonBaseElement::GetParentWnd() will give you a window...

That hides the parent window, which in this case is the status bar of the program. What I need is to hide only the progress bar itself. Maybe I should remove it from the status bar...

Here's how I create it:

// the progress bar is in the status bar
m_pMFCRibbonProgressBar = new CMFCRibbonProgressBar(ID_RIBBON_BTN_PROGRESS, 200 /* Bar width */);
m_pMFCRibbonProgressBar->SetRange(0, 100);
m_wndStatusBar.AddElement(m_pMFCRibbonProgressBar, "Progress", TRUE);

All the time I was looking for a Show method, there was CMFCRibbonProgressBar::SetVisible sitting right there before my eyes. Sometimes I'm dumb.

Right click on the datatype and select "Go to definition". That should help.

LPRECT is a pointer to RECT

LP here stands for LONG POINTER, i.e. 32-bit

typedef is not working properly..

Hi,

i am enhancing my application to support unicode characters...

Following is my code snippet:
---------------------------------------------------
typedef struct tagTIMEDATE {

DWORD Innards[2];

} TIMEDATE;

(structure being defined by Microsoft.(oledb.h))
typedef struct tagDBID
{
union
{
GUID guid;
GUID *pguid;
/* Empty union arm */
} uGuid;
DBKIND eKind;
union
{
LPOLESTR pwszName;
ULONG ulPropid;
/* Empty union arm */
} uName;
} DBID;

I used the following typedef now:

typedef TIMEDATE DBID;
------------------------------------------

Unfortunately, Compiler throws me an error (c2371) stating DBID is redefined;different basic types..
Previously, it was working fine. its not working after making my solution unicode supporting one in the project settings..

can anyone guide me how to solve this issue?

Thanks,
Rakesh

TIMEDATE and DBID are reserved datetype so you cant use DBID.

Make typedef TIMEDATE MY_DBID;

Hi, Karsten

But previously, it was working fine... in the sense, before converting my project settings to unicode...

If so, why is it not working now?

Re: Detecting memory leak

this looks like some type changing in the string section. Unsure | :~

or you can use #undef DBID Unsure | :~

this are all no good solutions... Cry | :((

Detecting memory leak

Hi all,

I have made a application in vc-2008 Release mode, but i have made all the debug option true in my code i.e i am able to debug my application in release mode also.

My problem is i want to detect memory leak in my application. I got this code in msdn

#define _CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>

_CrtDumpMemoryLeaks();

but it is mentioned that this code will work only in debug mode....

I am not getting that this code will work for me or not...

Can anybody please tell me? OR, is there any other way of doing so....

Thanks in advance

Ideally, you check memory leaks in debug mode and then finally change to release mode.
Are you writing configuration specific code?
If not you should be fine with checking leaks in debug mode.

IPictureDisp to byte array

18-Aug-09 20:34

Here is an article called Drawing horizontal and vertical gridlines[^], which is a very old one used to draw grid lines in a list control before it supported the LVS_EX_GRIDLINES style.
Change it to draw only lines for the rows.

You could try the GDI function GetObject[^] after getting the GDI handle using the HANDLE property of IPictureDisp.

Recently i have converted my project to VS2008 from VS2005.
My application crashes when we try to open a new job file from 'open' command.
Actually we have derived CFileDialog and added a preview on the right side of dialog.
So that when selecting the job iteself we can see the preview of it.
this works fine in VS2005. But it seems some problem after converting to VS2008.

Any solution to solve this problem.

Crashes in Vista machine alone. In Xp it works fine.

The crash is most likely a problem with the preview on the right side.
You should debug it and zero in on the problem.
