Have a look at CImage[^] (it loads jpg files)
Max.
This signature was proudly tested on animals.

I have come across this in the past and the only way I have found is to use the OleLoadPicture() function. There is an article here[^] on Code Project with some more information that may explain things.

You don't need CImage or any lib.
JPG is native in Win32 Shell (8 native methods to load them..)

Sorry, I don't understand what you mean by Win32 Shell in this context. Can you show me these methods and where they are in the MSDN documentation?

Hi,
When coding an initializer list for a base contructer e.g.
using the example below
where does c " int c " have to be declared somewhere in derived class "a" ???
Class a : public b
a() : b(int c)
thankx
|
|

|

Do you mean something similar to:
class B
{
int _b;
public:
B(int b):_b(b){}
};
class A: public B
{
public:
A(int c):B(c){}
};
void main()
{
A a(7);
}?
What's your trouble about?

If you want to initialize member variables of class b, you'd need something like:
class b
{
int num;
public:
b( int n )
{
num = n;
}
};
class a : public b
{
public:
a( int c ) : b(c)
{
}
};

In other words it has to be in the derived
class constructer paramter list BTW can
I pass "this" pointer in the derived class
paramter list e.g. a(this) : b(this)
Thankx

please look into the below code block.
HBRUSH CTestApplnDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
int nId = pWnd->GetDlgCtrlID();
CString sData;
if (nCtlColor==CTLCOLOR_EDIT)
{
switch(nId)
{
case IDC_EDIT1:
{
m_EditCtrl.FmtLines(FALSE);
m_EditCtrl.GetWindowText( sData );
}
break;
default:
break;
}
}
return hbr;
}
The m_EditCtrl.FmtLines(FALSE) causes crash in my application.
Please help me to sove this problem.

What is a "crash?" Is an exception thrown? Was an assertion fired? Have you used the debugger to verify that the edit control exists yet? If you comment that line, does the "crash" still occur (on the next line, perhaps)?

I have investigated with a test application and found that when including the following manifest definition in stdafx.h i am getting crash.
Crash occured in m_EditCtrl.FmtLines(TRUE);
However if i remove m_EditCtrl.FmtLines(TRUE); from OnCtlColor everything is ok.
What should i do?
#if _MSC_VER >= 1400
#if defined _M_IX86
#define PROCESSOR_ARCH "x86"
#define CC_PROCESSOR_ARCH "x86"
#endif
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='" CC_PROCESSOR_ARCH "' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif // _MSC_VER >= 1400

Sorry.
Yes it says

when i comment below line it did not crash.
m_EditCtrl.FmtLines(FALSE);

Use the debugger.

Does your edit box have the multi-line property set? FmtLines only applies if it is.
Quoting MSDN:
Windows will only respond if the CEdit object is a multiple-line edit control.
FmtLines only affects the buffer returned by GetHandle and the text returned by WM_GETTEXT.
It has no impact on the display of the text within the edit control.
Hope that helps.

Whether it did or didn't, that would not cause a "crash." The edit control will simply ignore the EM_FMTLINES message if the ES_MULTILINE style is not set.

I have found that calling FmtLines() inside OnCtlColor causes recurrsive call to OnCtlColor. This causes stack overflow and crashes the application.
Is there any possiblity to control this?

Why are you calling FmtLines() and GetWindowText() from within the WM_CTLCOLOREDIT handler?

Yes i have multi-line property set.

Are you using UNICODE in your build? There are some items within the CommonControl 6.0 that are only capable of operating with a unicode build, so perhaps that is your problem.
Try a simple test app - set for unicode - and see if it works, then modify to MBCS instead of unicode and try again.
Hope that helps.

I tried with test application.
It crashes in unicode build and in MBCS its ok.
However if add the following manifest then it crashes in MBCS also.
#if _MSC_VER >= 1400
#if defined _M_IX86
#define PROCESSOR_ARCH "x86"
#define CC_PROCESSOR_ARCH "x86"
#endif

#endif // _MSC_VER >= 1400
