Focus on Buttons missing in XP
Program written in MFC VC++ 6.0 - SP5, has been in use on everything from Window 95 up to XP Pro.
I have noticed that buttons and checkboxes on dynamically created dialogs (and maybe others) running on XP Pro do not show the dotted frame to indicate the control has the focus. I have observed this on PCs set up to use the Classic Windows style in XP. I do not know if the standard XP style also behaves in this way as I cannot change the setting. The same program displays these normally when run on NT4.
Does anyone know how to restore this desirable behaviour as it does not show which control has the focus.

It's a user setting, the user can choose to hide focus indicators and keyboard shortcuts (like underlined letters in menus).

Thank you. That fixed it once I found the place to change the entry.
A change with that effect is a bit subtle as it refers to underline of menu items but no reference to button focus.

Hi,
Is there control or class for visual html editing? Like the editing area of FronPage for example?
Thanks in regards!

Yes, It's the CHtmlEditView class. It is new in MFC 7. You just create a SDI application and specify the base class to be derived from CHtmlEditView and build it and you are done. You type into the view window, insert and move pictures etc and HTML is created for you. You can view it by right clicking on the view and selecting View Source.
Hope this helps.

Hi,All
In My application i am using CPropertySheet class for tabed dialog.
I have to change the Tab Cotrol Back color and TabColor.
For this i tried with
CMyDislplay::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
if( nCtlColor == CTLCOLOR_DLG)
{
pDC->SetBkColor(RGB(181,195,222));
pDC->SetTextColor(RGB(255,255,255));
return (HBRUSH)(m_pDlgBKBrush->GetSafeHandle());
}
HBRUSH hbr = CPropertySheet::OnCtlColor(pDC, pWnd, nCtlColor);
}
//CMyDislplay is derived from CPropertySheet.
In above trial the dialog color is changed,but Tab Color not changing
----
Can any one help me...
how can i change the Tab Color as wel as dialog color
thank in
advance..![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

I have been developing some application that requires the use of the windows com port. The windows driver seems to be behaving rather erratically when used with a non intel motherboard.
Symptoms:
Win XP/2K, intel motherboard, intel cpu
Windows serial driver works without error when receiving data from physical serial com port.
Win XP/2k, ALi/VIA motherboard with intel/AMD cpu,
Windows serial driver seems to be dropping data or had buffer overflow problems when receiving a few hundred kilobytes of data. Therefore the data i received when using the readfile(); would be invalid.
This is a very consistent problem and very repeatable.
Below is my configuration:
dcb.BaudRate= 57600;
dcb.fParity = FALSE;
dcb.Parity = FALSE;
dcb.StopBits= FALSE;
dcb.ByteSize= 8;
dcb.fOutxCtsFlow = TRUE;
dcb.fOutxDsrFlow = FALSE;
dcb.fDtrControl = DTR_CONTROL_DISABLE;
dcb.fDsrSensitivity = FALSE;
dcb.fRtsControl = TRUE;
dcb.fOutX = FALSE;
dcb.fInX = FALSE;
dcb.fBinary = TRUE;
dcb.fNull = FALSE;
dcb.fAbortOnError = FALSE;
I tried searching around for configuration advises to the windows com port for the ALI and VIA chipsets but couldn't find any writeouts on them.
Please do advise on this issue...
Best Regards

Hi, everyone!
I want to develop a remote desktop share/remote control
program, like terminal service in XP.
The reason why I want to develop a program like this has
two reasons:
1. I want to control the authentication method more flexibly,
for example, replace windows authentication method with
LADP method. But XP can only use windows authentication.
2. XP terminal service can not let more than two users to
share the same desktop.
My quetions are:
1. Does Microsoft have SDK to develop applications like this?
2. Are there some source codes that I can refer?
Thanks in advance,
George

VNC[^] is an open source cross-platform remote desktop application, so you should be able to modify that to include your own custom authentication.
I believe it allows multiple users to remote view the same desktop (and you can have a choice of just remote displaying the desktop, or actually allowing the remote user to control it)

I used most of time dynamic memory allocation. But I am asking my self how much could be a static allocated array in a Visual C++ application.
Is something related to Operatong System like : for 16 bit win mak is 64kbytes.
For the Visual C++ 6, I didn't found some specification related to this problem.
IS for sure the I tryed with a bigger buffer, but how sure could be ?
Thanks
Cutty

the maximum size of a statically allocated array in a function is limited by the size of the program's stack. the maximum size of an array allocated outside of a function is probably limited at run-time by the system (ie. how much memory is available).

Hi, all!
Here's a plain old C++ program that you have to modify such that it prints "Hello, world!" before it prints "Bye, world!":
<br />
<br />
#include <iostream.h><br />
<br />
int main()<br />
{<br />
cout<<"Bye, world!";<br />
return 0;<br />
}<br />
<br />
But here's the catch: You should NOT modify main() - in fact, you should'nt do anything to main() at all, but apart from that, you can do anything.
In fact, I already know of TWO ways to do this (of which one works everywhere and one works on Turbo C++ but not on VC++), and I just want to find out if there are any more.
Right now, it's 11 AM IST (5:30 AM GMT). I'll be back around 4:00 PM IST (10:30 AM GMT) for the answers.
Happy brain-racking!
Vikram.

This is not a standard C++ program, it uses iostream.h instead of iostream.
Surely if you create a class which prints hello world in it's constructor and create a global instance of it you'll get the desired result ?

Yeah, you've got a point. But that's not the point.

That's right. That's one way of doing it- the portable way.
The "other" way is doing it in Turbo C++  , like this:
<br />
<br />
#include <iostream.h><br />
<br />
void Hello()<br />
{<br />
cout<<"Hello, world!";<br />
}<br />
#pragma startup Hello<br />
<br />
int main()<br />
{<br />
cout<<"Bye, world!";<br />
return 0;<br />
}<br />
<br />
It does'nt work with the Win32 compiler (the pragma is implementation-dependant).
BTW, what happened to poor Vinod's article? Did it get chucked out? Poor guy!
I woulda loved to see his next article on RAM or something- his articles make funny reading. The humor content is way high.

It was removed and he was advised to modify and resubmit if he wanted to. I don't think he did.
I like the operator << solution better. iostreams rock. I dunno why I didn't think of it, because I play with them quite a bit. And when I said 'doesn't this work', it's because I didn't try it, and I too wasn't sure if iostreams were up and running prior to main(). I guess they are, but if the standard says they must be is another thing.

 So am I. I've got an eye for detail.
The << overload is definitely more "elegant", but you're indirectly modifying what is inside main(). So is the guy who used a #define on cout (see replies to this thread). That's something a purist (and pedants like you and me) would frown  upon. The cleanest solution (IMHO) is the global constructor. Anyway, I like the << overload best (though I'm a purist).
Poor Vinod. All he wanted was to make us laugh.
Any other solutions for the original question, do let me know at binarybandit@operamail.com .

Oh, absolutely. And the only one that does not modify main().

Yes, I like it too.

Declare a new << operator
ostream& operator << (ostream& os, char* str)
{
const char* temp = "Hello World!\n";
return os << temp << (const char*)str;
}this works because ostream has a <<(const char*) operator, but not a <<(char*) operator.

That makes it three. I never thought of doing it like this. One way I knew was what Christian said- use a constructor for a global object. The other is non-portable, and you can find it in my reply to Christian's post.
I guess I'm grateful (!) to you for this.

This is the best one. Personally I don't like the others because you might be making assumptions about initialization orders and such. Does the standard specify that iostream has been fully initialialized prior to main being invoked? Probably, but I am not sure.

I'm going to patent thought. I have yet to see any prior art.

This? What do you mean by this? The constructor or the operator overloading? The latter is more elegant, but the first one comes more readily to mind.
There's been another reply- somebody used a #define on cout itself (!).Check it out.

Vikram.

How about getting the preprocessor to do it for you?
#define cout cout << "Hello, world"; cout
I also came up withe the operator<< override myself, although I was a bit too unfamiliar to write it.

WOW!
I never woulda thought of that! Err... maybe I would, given some time. Anyway, full credits to you!
No offense meant, but if you see closely, I don't want anything inside main() to be changed. Your solution and the << overload solution indirectly do that. They change the behavior of what is inside main() from outside. A purist wouldn't like it. The "cleanest" is the global constructor solution, while the dirtiest is the pragma (see my earlier post for code).
Nice work!

Vikram.

How can I handle directories with space when passed into ParseCommandLine. It seems to treat them as paramaters. Any ideas?
ie c:\documents and files\
Thanks
