Use winzip. Or, if it's data, use the password as a key to encrypt your data.

I have the current date stored in:
COleDateTime date;
I want to pass this variable to a dialog class. I
I call my dialog class by using:
<br />
CEditDlg dlg(NULL, amount, date);<br />
And in the .h file of this dialog class I have:
<br />
public:<br />
CEditDlg(CWnd* pParent = NULL, CString amount = "", COleDateTime date = ""); <br />
If you look at the above line, COleDateTime date = "" is incorrect and I know its
incorrect. I tried making it COleDateTime date = NULL as well as COleDateTime
date(2006, 1, 1, 0, 0, 0) but nothing I have tried sets up this initial construction. I can make this work by passing a CString, but my big question is,
how can I properly write the standard constructor if Im passing a COleDateTime?
Please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

GDay everyone,
I'm a newbie in C programming.

GDay everyone,
Well, I tried it but. It does not work.
Here is my code.
How can I fix my code(below) to output the buffer msg_cat in function A from function B ?
Please help if you're interested in.
I'd appreciate it.
void A(){
char *msg;
char msg_cat[100] = "";
msg = (char *)recvfromDST (&read_EP, sockMulti);
strcat(msg_cat, msg);
strcat(msg_cat, "\n");
}
void B(){
if (strncmp(KB_buff, "display", 7) == 0){
}
}

You want buffer from function A here ? Is it?
then make function A look like this,
char* A()
{
char *msg;
char* msg_cat= new char[100];
memset(cat,0,100)
msg = (char *)recvfromDST (&read_EP, sockMulti);
strcat(msg_cat, msg);
strcat(msg_cat, "\n");
return cat;
}
function B would be like this,
void B()
{
if (strncmp(KB_buff, "display", 7) == 0)
{
call A here, and delete pointer returned after use.
}
}

[EDITTED]
Got the answer in MSDN forum. It turns out I had a large global array, which I had defined earlier to test something and had forgotten about it! ah...bad programming practice!;P
[/EDITTED]
Hi,
I have a relatively small Visual C++ project using MFC which allocates
unusually hight amount of virtual memory as soon as the program
starts(roughly 280MB), even before hitting the internal MFC stuff. When I
debug them program in Visual Studio 2005 with a breakpoint at the beginning
of int _tmainCRTStartup(void) function in crt0.c Windows Task Manager shows
the following information:
Memory Usage: 5,620K
Peak Memory Usuage: 5,620K
Page Faults: 1,420
VM Size: 282,360 K
Paged Pool: 632K
NP Pool: 2K
Handles: 102
Threads: 1
GDI Object: 6
Running the program in release mode produces the same result. Also,
compiler/linker settings are almost set to default.
My question why the program allocates so much VM, before even its started
WinMain() function? Is it a Windows issue or Visual C++?
Any help appreciated!

This is neither a windows or VC++ issue since it's not normal for a "plain" app unless you are using extensive DLLs especially from third party.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I am only using one thirdparty DLL coded by myself. SO I will have to investigate that.
Thanks for the lead.

Override the OnCtlColor method:
Ex:
if(pWnd->GetDlgCtrlID()==)
{
COLORREF clrStruct=RGB();
hbr = CreateSolidBrush(clrStruct);
pDC->SetBkColor(clrStruct);
pDC->SetTextColor(RGB(0,0,0));
}
You can do something like this.
Try this....

I didn't find that method

What version of editor are you using. VS6.0 / VS .NET 2003 or something else.

You can also add the code with your hands
In the header file
HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
In the .cpp file
HBRUSH CadfDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// Add your code here
return hbr;
}
In Message map of your class
ON_WM_CTLCOLOR()
But avoid doing so...

thanks,
it worked;
but with this i can't set a bitmap as a back round of the edit box;
|
|
|
|
|
HBRUSH CYourDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
CBrush m_Brush;
m_pBrush.CreateStockObject (NULL_BRUSH);
if(pWnd->GetDlgCtrlID()==IDC_STATIC1)
{
pDC->SetBkMode (1);
return (HBRUSH)mBrush;
}
return hbr;
}
I hope that your problem would be solved with this.

if you use VS2003 you can use from property window for insert WM_CTLCOLOR yto your class.

i'm in the end of the project;
and i dont think its a good idea to convert it automatically with wizard;

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*/).

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;
}
