Why new Image failed?

[yu jian]

<pre lang="c++">
Image* m_pImage;
CString strTempIMGPath = m_strCurrentImagePath;
wchar_t szFile[256] = {0};

char \*pStr = strTempIMGPath.GetBuffer(0);
int size = MultiByteToWideChar(GetACP(), 0, pStr, -1, NULL, 0);
MultiByteToWideChar(GetACP(), 0, pStr, -1, szFile, size);
strTempIMGPath.ReleaseBuffer();
if (m\_pImage != NULL)
{
    delete m\_pImage;
    m\_pImage = NULL;
}

<b> m_pImage = new Image(szFile, FALSE);</b>
if(m_pImage->GetLastStatus() == Gdiplus::Status::Ok)
{
...
}

After this statement,m_pImage = new Image(szFile, FALSE) the m_pImage is NULL, I do not know why create Image failed, after debug that I find that the szFile is a right PNG image file path. The last code used in a CDialog form, I use the CDialog::DoModel() to show this dialog in the CMyApp::InitInstance() I do not know whether I use this class Image too early, or I need use some code to initialize the GDI+ library?

replace the first line with this:

Image* m_pImage = NULL;

Otherwise, m_pImage is not NULL, and you are trying to delete uninitialised pointer, leadding to memory corruption

[Santhosh G_]

// Used for GDI+ initialisation.
ULONG_PTR m_gdiplusToken;

// Initialization of GDI+ library.
Gdiplus::GdiplusStartupInput gdiplusStartupInput;
Gdiplus::GdiplusStartup(&m_gdiplusToken, &gdiplusStartupInput, NULL);

The GdiplusStartup function initializes GDI+. Call GdiplusStartup before making any other GDI+ calls, and call GdiplusShutdown when you have finished using GDI+.

Very Good answer, thank you very very much.
