How to spacify the width of a string in 'scanf_s' ?
I feel hard, since the width of the string in the input file is not fixed varying from 50 character to 120, so how to specify the buffer size.
I used 'scanf' to read input, I do not need to specify the length of the string.
Please advise.
Thanks

Like this[^]...

If the size varies, you have to specify the maximum size, the smaller string will fit just fine in the larger strings array.

Yes, but this was a frequent cause of crashes due to buffer overflows, you don't HAVE to use scanf_s, if the previous version worked just fine for you, you can disable the warning with a pragma comment.

You have to use a buffer at least equal to the maximum string length of the input file (hence at least 120 characters long) and specify the size of your buffer (that is 120) in the scanf_s call.
Veni, vidi, vici.

Hi,

I do not think you can modify system options in this way.

okk...i am also trying to find some other way
bt while i was searching i found that i need to set ACSuspend value to 0 in registry
i found that from msdn link
http://msdn.microsoft.com/en-us/library/aa447563[^]
now i have to search how to programmatically edit the registry value(ie ACSuspend value)
btw thnx for your precious time....
if u find something instresting plz do keep me posted

You will need to use the Registry functions[^].

Judging by the first sentence here[^] it would appear that you cannot. Can you upgrade to a later version that supports C++/CLI?

Hi All
I implemented a multi touch application. I follow MSDN tutorial using manipulation interface, here:
http://msdn.microsoft.com/en-us/library/windows/desktop/dd371408(v=vs.85).aspx[^]
But I have many problems when panning or zooming, is not redrawing and glitches in scrren. I need to limit my CView and do panning when screen is bigger than CFrameWnd, because CFramewnd does not redraw. I don't know how to get frame size and limit CView to don't pass CFrameWnd size. I tried an anchor or dock window but did not work.
Please, I need any help.
Thank you.

The GetClientRect()[^] and GetWindowRect()[^] functions may be what you need.

Ok
I'm using GetWindowRect like MSDN example. But I have problems when panning. I have a CView with same size as CFrameWnd, if I move the screen beyond origin the screen does not redraw. What I need is do a panning only if my CVIew is bigger than my parent frame, and don't if Cview is in origin. I tried getting screen limits but does not work.
Example:
________________ --->CFrameWnd - Glitches and does not redraw
| |
| ___________|____ ---> CView - out of screen origin
| | |
| | |
| | |
| | |
| | |
|__|_______________|
Thank you.

I'm afraid that really does not tell us anything. Please show an extract of your code and try to explain exactly what results you are seeing and what you expect to happen.

Hey, everyone! I want to use one of the Find() methods with a richtextbox(RichTextmethod.Find Method(String, RichTextBox)) and i'd like to no if i might use a textbox's text instead of the string used in this method. thanks

I already gave you a link to the RichTextBox documentation here[^]. Check the links for the various overloads of Find() and select the one you need.

The text of a textbox is a string.

the program should;-
create list
search for a certain element within the list
insert an element after and beginning
delete element after and at the beggining
|
|
|
|
|
If you are asking for a complete solution then you should read points 2 and 11 here[^]. If you just want suggestions about lists then try the standard library[^].

You should
1. Review your class notes
2. Review your assigned reading
3. In the above review anything about lists specifically.
4. Write some code based on the assignment.
5. Test it.
