Problem in displaying image through CPictureHolder
-
Hi we are using CPictureHolder in order to display image through data. This data nothing but CString. we are doing the dcode(converting into byte) and creating the byte into CMemfile object. The problem is few image data not displaying the image. i am using below code. hr = ::OleLoadPicture(lpStream, maxLen, FALSE, IID_IPicture, (LPVOID*)&m_pPict); hr return as E_FAIL for some image data. please let me know what could be reason. Regards Gopal

From documentation:
This function returns S_OK on success. Other possible values include the following.
Return code
description
E_NOINTERFACE
The object does not support the specified interface.
E_POINTER
The stream is not valid. For example, it may be NULL.
So what's the actual return value you got? :)

That's in sharp contrast with the documentation. What is the numerical value?

Hi I am using DWORD to fine numerical value. I getting this value (2147500037) conver into Hex(80004005). it says that (#define OLE_E_NOTRUNNING _HRESULT_TYPEDEF_(0x80040005L));
