This method supports the standard return values E_FAIL, E_INVALIDARG, E_OUTOFMEMORY, and S_OK. Pictures loaded from a stream always own their resources. Ownership of this handle is determined by the fOwn parameter passed to OleCreatePictureIndirect. This parameter can be NULL if the caller does not need the handle. Ownership of the device context is always the responsibility of the caller.Ī pointer to a variable that receives the GDI handle of the picture. This parameter can be NULL if the caller does not need this information. I've also tried calling 'Invalidate' just to see if it would change anything. Syntax HRESULT SelectPicture(Ī handle for the device context in which to select the picture.Ī pointer to a variable that receives the previous device context. All the functions succeed (and I get meaningful data out of my IPicture object before calling 'Render'), but no matter what I do, I can't see anything on the screen, and excel always complains the answer to this command didn't return a valid thing. The sample is enclosed in the bottom of this post.

This method works in conjunction with IPicture::get_CurDC. As to the second solution, we also have a sample code for achieving conversion from Icon to IPictureDisp, this should work under. I dont see any code loading the image or creating the picture control you are talking about. Throws: ComException - if the retrieval fails.Selects a bitmap picture into a given device context, and returns the device context in which the picture was previously selected as well as the picture's GDI handle. In addition, the interface manages the rendering by passing it a device context. fileName - path to the file progId - the progID in string representation Returns: non-null valid object. So, while MSDN limits the capabilities of the IPicture interface to BMP, ICO, CUR and WMF pics, actually this interface supports non-animated GIF as well as JPEG pics. The caller to create a new instance without knowing stream and creates a new IPicture object you can use to display the picture. Type Parameters: T - the type of the return value and the type parameter of the class object of primaryInterface Parameters: primaryInterface - The returned COM object is returned as this interface.
