Anybody know a way to programmatically change the IE Connection Options? Is there an API or a specific registry key?
I need to change it from "Never dial a connection" to "Dial when a network connection is not present".
Like it or not, I'm right.

Look at the changes at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings. When setting the value from "Never dial a connection" to "Dial when a network connection is not present" the value EnableAutodial changes from 0 to 1.
Easy util for monitoring registry changes: http://www.sysinternals.com/ntw2k/source/regmon.shtml.
Succes!

Hi everyone,
I have a question, I am curious about the greatness of Cstring, can I used this in non MFC projects? I was trying to use it like this:
#include <Cstring>
#include <iostream>
int main(){
String str("The stars are aligned");
int n = str.Find('e', 5);
cout << n;
}
Code above contains an error "error C2065: 'CString' : undeclared identifier"
Did i miss something? or CString does not work with non MFC projects?
Thanks/Regards
Sidney

CString will not work in non-MFC projects, it derives from CObject.
If you are going to use STL you may want to consider the basic_string<T> template class.
Or WTL contains a version of CString in the atl_misc.h file.

BTW, basic_string<T> is typedef'ed to string in VC++

CString is part of MFC. You can use the STL string object in non-MFC apps. See this link [new window] for more information.

If you have VC++ 7, then you can use CString in non-MFC files by including the ATL headers. CString is now shared between ATL and MFC

Another thing is that I dont have VC++ 7 I'm using VC++ 6 so I guess I cant do this kind of thing right
Thanks/Regards

Correct. There are tons of implimentations of CString type classes if std::string does not do it for you though.

I use ShowWindow( SW_HIDE ) in my program and it flashes the frame of what would be the window but then it hides. I've tried commenting out a lot of stuff but nothing seems to work. How can I get rid of the flashing?

Try using this instead:
::SetWindowPos(hWnd, NULL, 0,0,0,0, SWP_HIDEWINDOW | SWP_NOACTIVATE | SWP_NOZORDER | SWP_NOMOVE | SWP_NOSIZE);

G'day all!
I have been using CRichEditCtrl class and every 20ms or so, I add things on to the display using this class. So you can imagine there's a whole heap of lines in the display.
I have been trying very hard to make sure that the Vertical Scroll Bar is placed at the latest updated position. Could anyone help me with this one?
Any help will be appreciated!
This above all, to thine own self be TRUE.

I didn't try the following but I believe it should work:
1) Call long GetTextLength() to get number character
2) Call long LineFromChar( long nIndex ) to get line index
3) You may want to call LineLength() to get line length
4) Call LineScroll() by removing the offset of the GetFirstVisibleLine( ).
CRichEditCtrl ctrl;
int nLine = ctrl.LineFromChar(ctrl.GetTextLength());
ctrl.LineScroll(nLine-ctrl.GetFirsVisibleLine());
Good luck!

I'm trying to programmatically size columns of a MSFlexGrid, but I don't understand, and have not been able to find documented, the proper way to do this.
In my case, I have a grid control on a dialog (it happens to be a tabbed dialog, but I don't know that that matters) and it will have 5 columns. I've put the following code in the OnInitDialog() function:
CRect rc;
GetClientRect(rc);
int Width = rc.Width();
Width /= (CellsPerRow + 1);
for ( int i=0; i < CellsPerRow+1; i++ )
{
m_TheGrid.SetColWidth(i, Width );
}
When this code executes, all the columns are tiny, scrunched up on the left side of the control. 
The docs for SetColWidth indicate that the argument is in "twips".
I have not been able to figure out what the units of CRect are.
So one question is: How do I convert from the CRect unit to twips. Presumably this is screen resolution dependent.
Another question/problem that I'm sure I'll have to face is: how to I account for the width of the vertical scroll bar on the right of the control. I have the scroll bar enabled, and I'm betting that the GetClientRect probably includes the scroll bar in its area.

How do you work with _variant_t variables?
I had a few variables in my ADO code which were declared as VARIANTS.
I changed them to _variant_t, and now the function crashes.
Essentially this is what I used to do:
VARIANT var;
VariantInit(&ar);
var.vt = VT_BSTR;
///set the var.bstrval to some string value
::SysFreeString(&var);
Now, I want to do the same thing with _variant_t, but it doesn't work!
How do you handle this simple scenario using _vairant_t?

_variant_t is a wrapper. It will free the contents for you, that is what it is for.

You can change the code that you have to this:
variant_t var;
var = ::SysAllocString(L"HelloWorld");
that is it. No initialization, it contains casting operators, and it will clean up the mess.
BTW, If you use variant_t, you will want to use _bstr_t as well for your BSTRs.

Hi,
I have problems converting a bitmap to buffer
and displaying it
I create my hdc,
I use CreateCompatibleBitmap(),
I FillRect() with a color,
I use the function GetDIBits(...)?
GetDIBits(
MemDC,
SaveBitmap,
0,
(WORD) pvi->bmiHeader.biHeight,
pData,
pbi,
DIB_RGB_COLORS);
to put the bit map into my buffer (BYTE pData) and i'm
missing something to display it to screen
I know i can display a red colored background
using :
prgb = (RGBTRIPLE*) pData;
for (iPixel = 0; iPixel < numPixels; iPixel++, prgb++)
{
prgb->rgbtRed = 255;
prgb->rgbtGreen = 0;
prgb->rgbtBlue = 0;
}
but a non uniform bitmap????

Create it as a DIBSECTION and you'll get access to the buffer by default. Chris has written a cool DIBSECTION wrapper here on CP.
