As Steve has already indicated, it looks as though you have mistakingly used the assignment operator in place of the equality operator. If you will get in the habit of putting constants on the left side of either operator, the compiler would have gladly complained about these statements. For example: if (0 = m_radio) // the compiler would have flagged this as erroneous A rich person is not the one who has the most, but the one that needs the least.

No. Check boxes are completely independent. coda_x wrote: Also, for radio buttons, are they assigned button1 = -1, button 2=0, button3=1 and so forth? No. They start from 0 (button 1=0, button 2=1 etc...) Ryan "Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late" John Nichol "Point Of Impact"

Wrap in a table like this: name: xxx horoscope: yyyyy

Use the line-height CSS attribute. Example: <div style="line-height: 2em;"> Double-spaced text goes here... </div> - Mike

Handle the BTNCLICK massage for the check box.Note associate a boollean member variable with the checkbox tocheck the current status.

Remember to call UpdateData() first so that m_check contains the current status of the check box. Ryan "Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late" John Nichol "Point Of Impact"

m_button =-1 "None Checked" m_button = 0 "button a Checked" m_button = 1 "button b Checked"

you will have to handle the onhscroll and on vscroll notification and scroll the window urself

yah something like that, do I add it as member variable to both view and all dialog classes using the "add member variable" in the class view tab and of type:boolean and public? Also , i have another problem: i need the current values of the dialog in order to draw to SDI view, but first i want to capture these values in the SDI doc class, how do i code that assumming the values needed are length, breadth from dialog A. The dialogs are modal.

thanx for replying. actually what i meant was how to set the visual view - white screen for drawing to half the window size so that i can place controls on the other half which is not on white blackground.:doh:

thanx for replying. i am considering alternative or setting state flags but i not sure how to code that in child dialog and view class's Onpaint().can you illustrate?

i am not very proficient in programming so can tell me how can i code that supposing my dialog is called dialog A? thank you

Then add the necessary parameters to InvalidateRect(). You might want to check out the scribble section at this web site. I know it is a MDI application but it should still work with a SDI application. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vctutor98/html/tutorhm.asp?frame=true You can find all this infomation on your MSDN Library disks that came with Visual C++ 6.0

thanx for replying. Can u elaborate on how i can re-display my image properly? My OpenGl coding was done in the dialog.cpp, then i should code the re-display in the view class OnPaint handler? I tried the following in the View class ONPAint message handler but unable to work: Void ProjectView:: OnPaint() { CPaintDC dc(this); InValidate(); UpdateWindow(); }

coda_x wrote: so that means AfxMessageBox cannot display a float directly? Correct. Check the docs and the function prototypes. Five birds are sitting on a fence. Three of them decide to fly off. How many are left?

erm, okie i a bit confused over this WM_PAINT thing, so what u are saying is that, if i code my draw rect in my dialog's WM_PAINT function and then i point it to my CView, the CView will not be able to show the rect on screen is it? i been trying to find out the best way to show my grpahics on SDI window whenever user input dimensions into my dialog...so i know i have a problem linking this dialog to my view.then the best way is to code all my drawing into the CView WM_PAINT function?
