Debugging Release version, built without debugging info, may lead to apparently strange results, I believe.

Maybe other codes bring memory error.
BTW, you can use CString here.

Why CString is supposed to behave better than std::string there (everywhere)?

Hi, i don't know FlexGrid but here's a general tip: when you specify a font for your cells or maybe for the entire grid, use a greek charset. In the LOGFONT struct there is a member called lfCharSet, if you set this to GREEK_CHARSET, the font mapper will try to give you a font that has greek characters in it. As said, i don't know the Flex Grid so i don't know how you can make it use a certain font but i guess you will know that. I hope this helps somewhat.

for Visual C++ try this otherwise getenv will work
using namespace System;
using namespace System::Collections;
int main()
{
Console::WriteLine();
Console::WriteLine( "GetEnvironmentVariables: " );
IDictionary^ environmentVariables = Environment::GetEnvironmentVariables();
IEnumerator^ myEnum = environmentVariables->GetEnumerator();
while ( myEnum->MoveNext() )
{
DictionaryEntry^ de = safe_cast<dictionaryentry^>(myEnum->Current);
Console::WriteLine( " {0} = {1}", de->Key, de->Value );
}
}

That's not C++, it looks like Managed C++ (which isn't really C++ but a different language based on it). This is the wrong forum for code like that.

One minute of googling turned up this code:
#include <stdio.h>
#include <stdlib.h>
extern char**_environ;
int main(int argc, char *argv[], char *envp[])
{
char **next = _environ;
while (*next)
{
printf("%s\n", *next);
next++;
}
return 0;
}</stdlib.h></stdio.h>
If you want to get the value of a specific variable you can use GetEnvironmentVariable()

I had created variable in user section , using the following code
'defining variables
dim objShell, colUserEnvVars
'initializing all variables
Set objShell = WScript.CreateObject("WScript.Shell")
Set colUserEnvVars = objShell.Environment("System")
'Output File for registry information.
colUserEnvVars("rahul") = "rahul"
but i cannot read the same from c++, for this i have to restart the system,
but Wscript.Echo colUserEnvVars("DeloitteAuditShare123") read the value without restarting ths system.

GetEnvironmentVariable( ) will work from VS2005 onwards. Have you tried that.

This API has been around since Windows NT 3.1 which was released in 1993. What makes you think that it is supported only from VS2005 onwards?

Can Any one please help me to get the screen shot of the windows opened in the desktop on CE Device machine. How would the screen shot be saved as bitmap file in the device machine.
A code snippet would be help ful.
Thanks in Advance

You need to have prnt_scrn.exe for capturing screen shot on a WinCE device.
Syntax of the Print Screen Tool
Prt_scrn [–d NUM] [-s Num1Num2] [–e Num1Num2] filename
Parameters of the Print Screen Tool
-d NUM
Specifies a number of seconds NUM to wait after running the Prt_scrn.exe application before taking the screen shot. The default value for NUM is zero.
-s Num1 Num2
Specifies the location of the upper left vertex of the rectangular region on the screen where to take the screen shot. The values Num1 and Num2 specify, in pixels, the horizontal and vertical coordinates, respectively, of this vertex. The default values for Num1 and Num2 are zero. The default values specify that the upper left vertex is the upper left corner of the screen.
-e Num1 Num2
Specifies the location of the lower right vertex of the rectangular region on the screen where to take the screen shot. The values Num1 and Num2 specify, in pixels, the horizontal and vertical coordinates, respectively, of this vertex. The values for Num1 and Num2 must be greater than the values specified in the -s parameter. The default value for Num1 is the width of the screen in pixels minus one pixel and the default value for Num2 is the height of the screen in pixels minus one pixel. The default values specify that the lower right vertex is the lower right corner of the screen.
filename
Specifies the path and file name of the .bmp file where to save the screen shot. To save the .bmp file to the release directory, add a \release\ prefix to the file name. The filename parameter is a required parameter.
Examples
The following code example shows syntax that instructs the Print Screen tool to take a screen shot on the target device three seconds after running Prt_scrn.exe. This example sends the screen shot to the Snapshot.bmp file in the release directory.
Prt_scrn –d 3 \Release\Snapshot.bmp
The following code example shows syntax that instructs the Print Screen tool to take a screen shot of the (100, 100, 400, 400) screen region on the target device. This example sends the screen shot to the Snapshot.bmp file in the Windows directory on the target device.
Prt_scrn –s 100 100 –e 400 400 \Windows\Snapshot.bmp

Hi..
I am new to this code project..
I have doubt on Visual c++..
My task is to scan the image and find the text in visual c++..
Once if i scan the alphabet it should called the library data base....
1.Create data base
2. How to include the images in the data base
3.Should we include the images in library files..
4.How to call the library files..
Could some one help me out ....
Thanks

You better seperate the images out of the database as separate image files in the desired format. In the database I would only list the relative path (!!!) to the image of an image directory or server.
Consider changing the image storage for the future!!!

MessageBox(hWnd,L"EnumWindows Successful",NULL,0);
