If your output is being flooded why dont you just re-direct stderr to a file.
console_app 2> stderr.log

I like that idea.
But this needs to be general. It's an "alert" library (a very minature logging library) that needs to detect on its own whether stderr has already been redirected.
Key idea: *auto-detect* where stderr is outputting to, and if it's going to stdout, skip over the requirement to write to stderr.
vprintf( alertMsg, msgArgs );
if( stdout != stderr )
vfprintf( stderr, alertMsg, msgArgs );
...
(Note: code is not complete; it needs some complicating va_end and va_starts in there to make it work correctly. Don't use it as a model!)

I have a LONG variable, x, and I need to use the value as an int for my "for" loop.
for (int i; i<x; i++)
How do I typecast a 'LONG' variable to an 'int'?
When I declare "i" as a "LONG" variable as such
for (LONG i; i<x; i++)
I get this error: no conversion from 'LONG' to 'LONG'
What should I do?
Thanks.

oups...forgot to ignore HTML tags
for (int i; i<variable; i++)
and
for (LONG i; i<variable; i++)

You shouldn't have to do anything special to use the LONG.
There's no requirement to use int in a 'for' statement. You can actually
put any valid code you want to in the three expressions (init/condition/loop).

It should work even as a type long (I'm not familiar with type LONG: if it's a composite type, then it won't work).
Any reason you can't just cast it to int at the point you are actually using it within the loop?
This should work (provided x is not a composite type)
for( x = someval; x < someotherval; x++ )
{
...
i = (int)x;
}

When I compile this code, it compiles with no errors (Visual C++ 6.0)
void test(void)
{
LONG x;
x = 800;
for (LONG i=0; i < x; i++)
{
}
}

The below code will work.
LONG lVal = 100;
int nVal = static_cast<int>( lVal );

Hello Folks,
I have started working on an Arabic Language Checker. Since I am new to this Unicode stuff therefore its a very basic level question.
The library function accepts Arabic word to be checked for spelling as wstring.
I have assigned char array the hex equivalent of Arabic word. Now the question is how do I convert this char array to wstring/wchar_t array. I googled this conversion but could not find any appropriate solution.
Kindly advice.
Regards,
Jinbaba

Since you are dealing with Unicode, why wasn't wchar_t used instead?
Look at MultiByteToWideChar(), or the A2W() macro.

Probably it was not Unicode, but a multibyte encoding such as CP 1256. These go to char arrays.

As the subject says,how to get it?
Thank you!~~

Get the file icon by calling SHGetFileInfo() with uFlags as SHGFI_ICON and you'll get the HICON handle.
Get the ImageList of your list ctrl and add the file icon to it by calling CImageList::Add(), so that you can add that icon to your list ctrl. For adding new item to list ctrl, refer http://www.functionx.com/visualc/controls/listcontrol.htm[^]
Regards,
Jijo.

here's the situation:
we have an application which uses an embedded instance of IWebBrowser2, and this browser is intended to be used on a site which requires a secure login. so, the user will bring up the browser window embedded in our app, login, and do his work. this works fine until the site in question has a pop-up window - when that happens, the embedded browser launches a new instance of IE for the popup, which means the popup doesn't get any of the security information / cookies from the main browser window, and it will force the user to re-login. we want to prevent that.
a poster here[^], suggests that the way to deal with this is to handle the NewWindow2 notification, create a new embedded browser in the handler, associate that with the main browser and let the new browser take care of the popup. i guess that sounds logical, but i'm not sure what that means in terms of new threads and new objects (and who cleans them up). the documentation is pretty weak, as usual.
so, has anyone else ever done anything like this ?

No have you. The KB seems straight forward. Let us know if it works will you?
