Form Scrolling Problem
-
Hi, for 3 days i'm trying to make my form resizable. Well, in desing mode, as my form has the VScroll property true, i increase the bottom of the form and then when i run it the scrollbar appears and works. I want to do that but by code, to increase the form's bottom as i'm going to dinamically filling it with objects, i'm doing like: CRect myRect; for (int i=0;i<100;i++) { caramba[i] = new CStatic; g.Format("%d", i); caramba[i]->Create(g, WS_CHILD|WS_VISIBLE|SS_CENTER|WS_BORDER, CRect(10, i*10, 120, i*10+50), this); myRect.bottom+=20; } MoveWindow(myRect.left, myRect.top, myRect.right, myRect.bottom); this->GetParentFrame()->RecalcLayout(); The objects are drawn in the form until number 65, well until the regular size of the form, and the scrollbar do not appear. How can i make the VScrollbar to appear as the form size increases? Thank you in advance

Thank you Lucy, i tried your suggestion, i did like: CRect myRect; CSize mySiz:omg:e; this->GetClientRect(&myRect); mySize=myRect.Size(); for (int i=0;i<100;i++) { caramba[i] = new CStatic; g.Format("%d", i); caramba[i]->Create(g, WS_CHILD|WS_VISIBLE|SS_CENTER|WS_BORDER, CRect(10, i*10, 120, i*10+50), this); myRect.bottom+=20; } MoveWindow(myRect.left, myRect.top, myRect.right, myRect.bottom); this->GetParentFrame()->RecalcLayout(); this->SetScrollSizes(MM_TEXT, mySize); this->ShowScrollBar(SB_VERT, TRUE); this->SetScaleToFitSize(mySize); Even using SetScrollSizes and ShowScroll after RecalcLayout, it apears for half a second or something, and then disapears again. I tried SetScaleToFitSize and it did not improve Why does this appends? Thank you in advance

I am not sure. But I think you need to give the total size to SetScrollSize. that is, the size of your document. Excuse me for my poor English, let me give you an example. Say you are opening a document which will occupy a 800x600 screen. But your window is only 400x200 big. So you set the scroll size to be 800x200. And the vertical scroll bar and horizontal scroll bar will appear for your to scroll to see the other part of the contents. If you are using this->GetClientRect() to set scroll size, you are telling Windows that the screen needed is of the same size as the screen allocated. So, no scroll is necessary. Hope this helps.
