Scroll bar not moving

[martenbengtsson]

Hi,
I have added a scroll bar to one of the splitter windows in my application. I see the scroll bar but it wount move.
Here is the initialisation

void CTableView::OnInitialUpdate()
{
CView::OnInitialUpdate();

// TODO: Add your specialized code here and/or call the base class
CSize sizeTotal;
// TODO: calculate the total size of this view
sizeTotal.cx = 180;
sizeTotal.cy = 1000;
SetScrollSizes(MM_TEXT, sizeTotal);

}

The OnDraw function looks like this,

void CTableView::OnDraw(CDC* pDC)
{
CGsdoc_b1Doc* pDoc = GetDocument();
// TODO: add draw code here
RECT rct;
int textY = 0;
int textX1 = 0;
int textX2 = 0;
int i = 0, j = 0;
short tmpVal = 0, decimal = 0, integer = 0;
unsigned char lsbVal = 0, msbVal = 0;
float floatVal = 0;
CString strTemp;
int numTempVal = 0;
int minute = 0;
int hour = 0;
CString strTime;


ASSERT_VALID(pDoc);
CPen blackPen;
blackPen.CreatePen(PS_SOLID,1,RGB(0,0,0));
CPen* pBlackOldPen = pDC->SelectObject(&blackPen); //Select aPen as pen
if(pDoc->GetGraphComplete())
{
textX1 = 25;
textX2 = 110;
textY = 32;
rct.left = 20;
rct.top = 30;
rct.right = 190;
rct.bottom = 50;

pDC->Rectangle(&rct);
pDC->TextOut(textX1, textY,"Tid");
pDC->TextOut(textX2, textY,"Temperatur");

numTempVal = (pDoc->m_FileSize-5)/2;

for(i=0; i<numTempVal; i++)
{
rct.top = rct.bottom;
rct.bottom = rct.bottom + 20;
textY = textY + 20;

lsbVal = pDoc->m_FileBuffer[j];
j++;
msbVal = pDoc->m_FileBuffer[j];
j++;
tmpVal = msbVal << 8; //store and shift up MSB of data value
tmpVal = tmpVal | lsbVal; //concatenate MSB and LSB
integer = tmpVal / 10;
decimal = tmpVal % 10;
floatVal = decimal*0.1;
floatVal = integer + floatVal;
integer = floatVal;
strTemp.Format("%d", integer);

minute = pDoc->m_Minute + i;
hour = pDoc->m_Hour;

if (minute >= 60)
{
hour++;
minute = minute-60;
}

if(hour >= 24)
{
hour = hour-24;
}

strTime.Format("%d%s%d", hour, ":", minute);
pDC->Rectangle(&rct);
pDC->TextOut(textX1,textY, strTime);
pDC->TextOut(textX2, textY, strTemp);
}
pDC->MoveTo(105,30);
pDC->LineTo(105,rct.bottom);
}
}


Happy for any help.

What is CTableView?
What has drawing code to do with your scroll bars problem?

How did you add the scroll bar? Note that in order to use SetScrollSizes(), you have to use a CScrollView or CFormView. If you added the scroll bar yourself, you will also have to handle the scrolling messages and do all the required calculations like SetViewPortOrg() etc. yourself.

My big misstace was that I did'nt let Visual Studio create a ScrollView class. I tried to do it myself but I must have missed something in the OnScroll handling.

Next time I let the tool do the jobb, thanks for the reply.

Try SetWindowOrg, SetWindowExt, SetViewportOrg, SetViewportExt
