" is the C-style strings delimiter.
\" is the " character within a string.

I didn't clearly understood your question but if you want to use a " character inside a string, you can use '\"' as an escape sequence:

char* szString = "A string with a \" in it";

This will give you that if you print it:

A string with a " in it

I have the following code in MFC but it says type cant be converted from Varitant to Class1

void VRMControl::SetVariant(VARIANT VariantParam)
{
Cls::Class1 *obj = (Cls::Class1) VariantParam;
}

Class1 is an user defined class; how can i convert this type and i need access the members of Class1 thro VariantParam. While calling im sending the object as Cls::Class1 type.

A VARIANT is a big struct, casting the VARIANT itself is meaningless (even if you fix the cast/assignment to obj). You need to know which field of the VARIANT the caller set and read that field.

Where are you creating the DC, i.e. dcMem? Doesn't it ASSERT?

I guess that's because your m_hInstance parameter is NULL. This could be because the current application instance has not been created. Unsure | :~

Unless and until InitInstance returns successfully I don't think the instance handle will be created. Unsure | :~

If your application is dialog based
Write your code in OnDraw or initdialog of dialog instead of Initinstance() of application
