Hi,
I did as follows in that order & I get the child control to exceed the parent window.
childControl.SetParent(GetDesktopWindow());
childControl.ShowWindow(true);
childControl.BringWindowToTop();
childControl.SetFocus();
childControl.MoveWindow(500,300,400,200);
But now the problem is ,I don't get the childControl as an activeWindow(Can't select,edit anything etc).
Thanks..

just declare a boolean flag which you switch in your OnStop() function...

Try AfxEndThread(..,..)
void AFXAPI AfxEndThread(
UINT nExitCode,
BOOL bDelete = TRUE
);
This will end the current thread.

Hi all
I've been teaching C++ for about 10 years (unmanaged using Borland Compilers), and for the first time this year I am teaching managed C++ using MS Visual Studio .NET. The first part of the course concentrates on procedural programming in a console environment, and one of the topics is writing / reading to text files (which is OK), and printing data to a printer (local LPT1 printer). In unmanaged code, I would write is as follows :
#include <fstream.h>
void main(void)
{
char data[80];
ifstream infile;
ofstream printer;
infile.open("TEST.TXT", ios::in);
printer.open("PRN");
while (infile)
{
infile.getline(data,80);
if (infile)
{
printer << data << "\n";
}
}
};
However, I cant find a simple way to set up a stream to the local printer in a console based environment using managed code. The file handling part is fine, and would look as follows :
// Filein1.cpp
#include "stdafx.h"
#using <mscorlib.dll>
using namespace System;
using namespace System::IO;
int _tmain()
{
String *record;
StreamReader * fileIn = File::OpenText(S"Test.txt");
// Need to set up stream to printer here
while ((record = fileIn->ReadLine()) != 0)
{
Console::WriteLine(S"{0}",record); // need to replace with output to printer stream
}
Console::ReadLine();
fileIn->Close();
return 0;
}
Can anyone help me fill in the gaps ?
Many thanks
Simon Cornish

Does anyone know how to use this!
I need to make the background of my AVI transparent. I'm capturing the OnCtlColorStatic message, but what next?
I search the docs and the web but have found conflicting examples. Should I be returning a BOOL from this message (to say I've handled it) or a HBRUSH? or something completely different!
I'm lost - Can anyone shed any light on this (a snippet of code would be useful!)
Kevin.

Have you set the ACS_TRANSPARENT style when you created the control? That should be all you have to do.

Hello
How can one make a tooltip alpha blended? I've grabbed the code from MSDN, and added a WS_EX_LAYERED style to the tooltip and call to SetLayeredWindowAttributes(), which seems to be enough. But it does not work. Here's code:
void CreateMyTooltip (HWND hwnd)
{
// struct specifying control classes to register
INITCOMMONCONTROLSEX iccex;
HWND hwndTT; // handle to the ToolTip control
// struct specifying info about tool in ToolTip control
LPTOOLINFO ti;
unsigned int uid = 0; // for ti initialization
char strTT[30] = "This is your ToolTip string.";
LPTSTR lptstr = strTT;
RECT rect; // for client area coordinates
/* INITIALIZE COMMON CONTROLS */
iccex.dwICC = ICC_BAR_CLASSES;
iccex.dwSize = sizeof(INITCOMMONCONTROLSEX);
InitCommonControlsEx(&iccex);
/* CREATE A TOOLTIP WINDOW */
hwndTT = CreateWindowEx(WS_EX_TOPMOST,
TOOLTIPS_CLASS,
NULL,
WS_POPUP | TTS_NOPREFIX | TTS_ALWAYSTIP | WS_EX_LAYERED| WS_EX_TOOLWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
300,
200,
hwnd,
NULL,
NULL,
NULL
);
SetLayeredWindowAttributes(hwndTT, 0, (255 * 70)/100, LWA_ALPHA);
gOldTooltipWndProc = (FARPROC)SetWindowLong(hwndTT,
GWL_WNDPROC,
(DWORD)TooltipWndProc);
/*SetWindowPos(hwndTT,
HWND_TOPMOST,
0,
0,
0,
0,
SWP_NOMOVE | SWP_NOSIZE | SWP_NOACTIVATE);*/
/* GET COORDINATES OF THE MAIN CLIENT AREA */
GetClientRect (hwnd, &rect);
/* INITIALIZE MEMBERS OF THE TOOLINFO STRUCTURE */
ti = new TOOLINFO;
ti->cbSize = sizeof(TOOLINFO);
ti->uFlags = TTF_ABSOLUTE | TTF_TRACK;
ti->hwnd = hwnd;
ti->hinst = NULL;
ti->uId = uid;
ti->lpszText = LPSTR_TEXTCALLBACK;//lptstr;
// ToolTip control will cover the whole window
ti->rect.left = 0;
ti->rect.top = 0;
ti->rect.right = 0;
ti->rect.bottom = 0;
/* SEND AN ADDTOOL MESSAGE TO THE TOOLTIP CONTROL WINDOW */
SendMessage(hwndTT, TTM_ADDTOOL, 0, (LPARAM) (LPTOOLINFO) ti);
SendMessage(hwndTT, TTM_TRACKACTIVATE, (WPARAM)TRUE, (LPARAM)(LPTOOLINFO)ti);
gHwnd = hwndTT;
gpTi = ti;
}
What am i doing wrong? Thanks for help

Hi All,
I am in a bottleneck and need your help to come out of it. I have a Shell DLL which will load from a USB CDROM media. When the shell is loaded and my computer is open the tray Icon on the system tray is not allowing me to stop the device. To overcome this I have to logoff logon each time. I tried the normal ways of Unloading the shell DLL (By using DllCanUnloadNow()) still no use.
Thanks for your help in advance,
Raja.

Hello,
I'm trying to modify a black&white bmp file by replacing certain areas with the data obtained from other bitmaps. I have no problem in doing this with the gdi+ functions. My problems have arrived when I have tried to insert strings in some places in the bmp file. I just don´t know how to do it. Can anybody give me the clue?
Any help will be really appreciated,
Itziar

If you are using GDI+, use
DrawString( ) with SetTextRenderingHint() and SetInterpolationMode.

Thank you for your help. I´ll have a look at these functions, but one more question, aren´t they used to display images? You see, I want the text to be saved into the bmp file. I´m not displaying images.

You can take the Graphics object of a bitmap and draw directly to it. You can then save the Bitmap using the Save method.

Any idea ?

Hello.
You can use stat() / _stat()
Or _access()

Hi,
CreateDirectory will return ERROR_ALREADY_EXISTS if the specific directory already exists.

Hi,
I am creating a shell namespace extension to show FTP files. I implemented cut / copy and paste using CFSTR_FILECONTENTS and CFSTR_FILEDESCRIPTOR. I implemented IDataObject and IStream for this. After copying, when I choose to paste the files, I am getting all the files, But the problem is that, the directory structure is not retained.
If I am copying a folder say "Test", which contains 2 files
1. a.txt
2. b.txt
When I choose paste, I am getting 2 files ( a.txt and b.txt ) and a folder ( Test ) in the same place. In fact it should have been folder "Test" and the two files inside "Test". But that is not happening.
I believe I am missing something here...
Could somebody please help me in resolving this.
Thanks and Kind Regards
Jugs
