Hi, My code in OnInitialUpdate is sizeTotal.cx = 1000; sizeTotal.cy = 300; // TODO: calculate the total size of this view SetScrollSizes(MM_TEXT,sizeTotal); Instead of passing the hardcoded values 1000,300 i want them to change them dynamically. eg: sizeTotal.cx = m_nHeight; sizeTotal.cy = m_nWidth; This gives me an assertion error. How can this be achieved. Thanks and regards, Salil.

Hi , When i use the scrollbars the position of the window also changes. Can i attach my code instead of pasting it? Thanks and regards, Salil.

Hi I have 5 seperate Device contexts in which i load 5 bmp's and position them on the screen such that it looks as if it is 1 bmp. How to combine these 5 dc's into 1. Thanks and regards, Salil

Hi All, I read ther article by VGirish, on how to use CScrollView and scroll bmp's in an MDI appln. I tried it out but it does not work. Can any one tell me how do i scroll a bmp using CScrollView in an SDI application. Thanks and regards, Salil.

Hi, I am merging 5 bmp's and displaying them as a single bmp in the OnDraw(). The bmp does not get scrolled when i move the scrollbar.Instead if i draw a rectangle it gets scrolled when i move the scrollbars, why does not the bmp get scrolled?
