Hi
Can anyone tell me if it is possible to use a time delay when working on a console application.
Say if I needed to wait 3 seconds before displaying output to the screen.
eg:
char name;
cin << name;
// delay output for 3 seconds ***
cout<< name;
Web searches have proved useless so if anyone has any useful links or code it would be greatly appreciated !!!!!
Thanks in advance.
I really hate this darn machine;
I wish that they would sell it.
It won't do what I want it to,
but only what I tell it.

Use Sleep(3000);
1 milli second=(1/1000) seconds
However, avoid using Sleep(/*time interval*/).
Somethings seem HARD to do, until we know how to do them.

Ahhhhhhh
Thanks AnShumAn
Tried the Sleep earler but was using the (s) in lower case instead of upper.
Cheers for the help, just need to read things better next time.

Hi there,
I created a dummy MFC app in VS2005. All I want to do is to paint the view black color. When I resize the window, the view is flashing white color all over. I thought painting to an off-screen DC then calling BitBlt could avoid that.  Can someone please tell me how? Thanks a lot!
This is my OnDraw function.
void CtestView::OnDraw(CDC* pDC)
{
CtestDoc* pDoc = GetDocument();
if (!pDoc)
return;
CDC offScreenDC;
CBitmap offScreenBitmap;
CBitmap * pOldBitmap = NULL;
CRect clientRect;
GetClientRect(clientRect);
if (offScreenDC.CreateCompatibleDC(pDC))
{
if (offScreenBitmap.CreateCompatibleBitmap(
pDC,
clientRect.Width(),
clientRect.Height()
)
)
{
pOldBitmap = offScreenDC.SelectObject(&offScreenBitmap);
}
}
CBrush brush;
CBrush *pOldBrush = NULL;
if (!brush.CreateSolidBrush(RGB(0, 0, 0)))
return;
pOldBrush = offScreenDC.SelectObject(&brush);
offScreenDC.FillRect(clientRect, &brush);
pDC->BitBlt(
clientRect.left,
clientRect.top,
clientRect.Width(),
clientRect.Height(),
&offScreenDC,
0,
0,
SRCCOPY
);
offScreenDC.SelectObject(pOldBrush);
offScreenDC.SelectObject(pOldBitmap);
}

Override OnEraseBkgnd and do nothing, return simply true.
like this;
void CtestView::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}

Hi,
By using MFC Appwizard I have created a project.
Say FirstApp as an SDI application and chosen the Header files only as databasesupport.
I wrote a function in FirstAppView class to get the database connection.
After that I have inserted another Dialog resource and added a few controls for it and then added a new class for it.
Now I want to invoke the function which I wrote in FirstAppView class.
Can you plz say How can I do that?
Thanks in advance.

Hi Prasad,
Actually I tried this way but I got an error saying that my application class is not derived from CWnd.
Can u say how to overcome it.
Thanks in advacne.

Can you show some code?
I assume your application is SDI with Doc/view support. and you have a dilaog class from which you want to access a function in view class, isn't it?

Thank you very much for both of you.
I have another doubt shall i ask you?
I wrote code like this.
while()
{
.....
.....
//a query to insert data into database.
....
}
I want to stop the execution for sometime say 2milli seconds after insert query.
How can I do that?
Can I use sleep() method here?

Hi, I need to read 5 rows by 5 columns of numbers from a text file into a 2D integer array.
How do I do it in C++?
e.g
10101
00011
10111
01110
10010
I've already created a 2D array and the necessary statements which are used to read from a text file.
i.e
int data[5][5];
ifstream inClientFile("Data.txt", ios::in);
|
|
|
|

first read all data in any string then reterive useful text from it!
