Try to save this file as c:\common.manifest
and set it (c:\common.manifest) at ProjectSettings->ManifestTool->InputAndOutput->AdditionalManifestFiles  :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">

This was incredibly helpful. It also seems to be the only place I can find where this is actually documented. Thank you.

Hi,
I am opening an aspx page using the following code.From that aspx page,i will return some value using Response.Write("hi"); function.I want to get this string.How to get it from the aspx page to VC++.
CInternetSession objInetSession;
char szURL[100];
CStdioFile* objStdFile;
try
{
wsprintf(szURL,"%s","http://101.8.0.24/test/test.aspx");
objStdFile = objInetSession.OpenURL(szURL,1,INTERNET_FLAG_TRANSFER_ASCII ,NULL,0);
}
catch(CInternetException* exp)
{
exp->ReportError(MB_OK,0);
}
Thanks,

use CHTTPFile and CHTTPConnection.

Hello, I use this code. It's only a little
different and it should answer your Question.
CInternetSession objInetSession;
CHttpFile *pHttpFile;
CString tmpStr;
char inBuf[10000];
UINT nBytesRead;
try
{
pHttpFile =(CHttpFile *) objInetSession.OpenURL(
CString("http://localhost"),
1,
INTERNET_FLAG_TRANSFER_ASCII,
NULL,
0
);
}
catch(CInternetException* exp)
{
AfxMessageBox((LPCTSTR)"Some thing went astay",0,0);
}
nBytesRead = pHttpFile->Read(inBuf, sizeof(inBuf));
AfxMessageBox(CString(inBuf,nBytesRead));
}
return nRetCode;

Hi,
I got one CZoomView sample file form code project.Actually i want zoom fucntion in my applcaiton for every view.In tht,initially when i set scrollposition,extra window is appearing.
For example,in OnDraw(),i set background of window as black
CRect mClientArea;
GetClientRect(&mClientArea);
pDC->FillRect(&mClientArea,&CBrush(RGB(0,0,0)));
I set scroolsize as
m_layout.cx = GetSystemMetrics( SM_CXSCREEN );
m_layout.cy = GetSystemMetrics( SM_CYSCREEN );
m_page.cx = m_layout.cx/2; m_page.cy = m_layout.cy/2;
m_line.cx = m_layout.cx/50; m_line.cy = m_layout.cy/50;
SetScrollSizes(MM_TEXT, m_layout, m_page, m_line);
What happended is after execution,when i scroll the horizonatal or vertical scrolls,the window is scrolling more than actual window rect.
More white screen is appearing apart for black background.How can i avoid that? Because while zooming,if user move the scrolls,then extra empty window will appear.i want to avoid that.

I want to use std::stringstream to format data to a string like sprintf "%02d" as below:
char szWord[MAX_PATH];
int nValue=3;
sprintf(szWord,"%02d",nValue);
How do I do that by std::stringstream?

stringstream does not print, but iostream does. Try the cout object as follows:
int x(3);
std::cout.setfill('0');
std::cout.setw(2);
std::cout << x << endl;
stringstream is used similarly, but as I said before it writes to memory, not the console.
Edit: did not pick up on the formating earlier.

There is (I have been told) a way of using an entire dialog template as a resource in another dialog. This would be very usefull in organising things like a property sheet in one corner and something else in another place. Has anyone tried the mechanics of this?
Regards,

You don't use a dialog template as a resource in another dialog - to me this implies merging. I've never seen this done.
What is common is to:
- define the parent dialog template
- on the parent, define where a child dialog is to be placed by using a dummy control
- in the parent WM_INITDIALOG:
- call CreateDialog*() to create the child dialog from its template
- find the dummy control and it's extents
- delete the dummy and resize/position the child dialog to take its place
...cmk
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

'W' is supposed to be a wide character so use L'W'
You may be right
I may be crazy

As a side note, your loop limits are wrong, you should use
for (n=11; n>=0; n--)
or, better
for (n=wcslen(S)-1; n>=0; n--)

If this is your actual code, you aren't getting that error. S[n] returns a wchar_t, not a LPWSTR. 'W' doesn't need to be L'W' since it will auto-promote to wchar_t.
(Plus, for(n should be for(int n.)

Joe Woodbury wrote: 'W' doesn't need to be L'W' since it will auto-promote to wchar_t.
That should not be true.
It was true with old C++ version, where the wchar_t was not an independent type, and was just a typedef for "unsigned short", and "char" autopromote into "short" and become "unsigned".
In more modern versions, wchar_t can be set up as an independent type with a compiler switch and -now- it becomes a default by standard.
Autopromotion of char-s into wchar-t must not happen, since the "encoding scheme" used in strings may not fit: All negative chars (above 127) are not ASCII and hence may have different meaning if ANSI (depending on the codepage) or UTF (can be UTF-8).
That said, char to wchar_t is not a one-to-one arithmetic conversion. You may have four chars going into a single or a pair of wchar_t (think to UTF-8 to UTF-16 chinese).

Good to know, but weird, in my opinion.

That's was what i though when that differentiation was introduced.
But it saved me lot of time form char-type mismatching in strings!
The "werid" thing is that C++ is still taking the old C idea of "char are just numbers" and strings don't exist (there are character arrays and string manipulation functions).
Than wchar_t was introduced, and a type semantic was applied to it.
It would be more correct -nowadays- the case that even char should not have number semantic and a different type (may be byte and unsigned byte, or short short int) should be introduced to represent small integers)
I also wander why C and C++ standard are insisting with all those sort of short, long, long long, long long long, etc. instead of simply define integers as int_x where x is the number of bits (MS does it, but it's not "standard").
Then there might be char_x, incompatible with int_x unless of explicit conversions and functions.

This is more funny I don't know if it's related to the new standards or if not.
My program has a linked list data structure in C++.
So...
class Whatever
{
public:
LPWSTR *Info;
};
is my basic data structure.
I store info along the way from a ComboBox in a Whatever data structure.
Eventually I want to process several of Info and divide them in several Strings.
if (Test->Info[n] == L'/')
{
}
I end up getting these errors.
1>main.cpp(686): error C2446: '==' : no conversion from 'int' to 'LPWSTR'
1> Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
1>main.cpp(686): error C2040: '==' : 'LPWSTR' differs in levels of indirection from 'int'
However if I address LPWSTR directly not through the C++ class data structure everything goes smooth as silk.
