Basically a shell replacement? Just replace the shell with your program (some registry key somewhere), and don't allow that user to run Explorer.exe.
I need to know how to avoid that the OS shows the user the phrase: "press F8 keyboard to show the start menu options"
I'm not familiar with XP, but is it really the "OS" that displays this? It seems more logical that it would be just Explorer, and in that case it should be as easy as what I have suggested.

first of all thank you for your answer...
Mike Nordell wrote:

I don't think that this can be an easy thing... and the fact that is the OS that shows that phrase seems clear...
I think that other versions of Windows made something similar but in Win2K Professional and XP Professional while the OS is being loaded and the first progress bar appears (not in graphical interface) under that progress bar can be read something about pressing the F8 key in order to show a safe startup menu.
I want to avoid that fact.
And, of course, it would be easy if the OS would be loaded and the system wide keyboard hook that I have installed could affect that, but as the OS is still not loaded it must be a flag/feature changeable somewhere in windows in order to avoid to show that.
Thank you in advance.

Why can't I use sizeof to find the size of a static data array within a class. It works fine if I use sizeof outside the class.
class myclass
{
public:
static char myarray[];
void myfunction()
{
// VC6 compile error: illegal sizeof operand
// GCC 3.2 'sizeof' applied to incomplete type 'char []'
// cout << sizeof (myarray);
}
};
char myclass::myarray[] = "this is a string";
int main(int argc, char* argv[])
{
myclass mc;
cout << sizeof(mc.myarray); // works
//mc.myfunction();
return 0;
}
another alternative I tried was to make the array const but this only works using GCC on linux; using VC6 I get errors.
class myclass2
{
public:
//VC6 error C2258: illegal pure syntax, must be '= 0'
//VC6 error C2252: 'myarray' : pure specifier can only be specified for functions
static const char myarray [] = "this is another string";
void myfunction()
{
cout << sizeof(myarray);
}
};
int main(int argc, char* argv[])
{
myclass2 mc2;
cout << sizeof(mc2.myarray); // works
mc2.myfunction();
return 0;
}
Thanks if anyone can help.

myarray must be defined before it is used as a parameter to sizeof, so you can't use it inside a class definition. compiler needs to see the definiton of the array to know its size.
Define the function in cpp file, after the myarray definition:
void myclass::myfunction()<br />
{<br />
cout << sizeof (myarray); <br />
};

In the SDI creat with Internet Explorer Style and a use HtmlView rather than CView? So on the left side, I created Tree (TreeView)?
How do I get the HtmlView to change the website, when I click different node in the tree? in short, How can CHtmlView get the treeview has changed message??
HELP

When the selection in a treectrl changes it sends a TVN_SELCHANGED message. When you implement a WM_NOTIFY handler for that message in your treeview's message map, you can react on that event appropriately. In your case this could be calling the Navigate2 functon of your htmlview, passing the desired page.

you can detect leftclick and see if a item was selected.

I think what you need is to register you application to the registry.
--> check the registry section.
check on how to write system tray - there are some good one in cp.

You can write the info about you app onto HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Runtype regedit on the Runand check it out??
NAME -- wirte your applicatoin name
Type -- REG_SZ
Data -- write the full path of your program..

http://www.codeproject.com/system/
go down to Registry and find out how to write and read....
http://www.codeproject.com/dialog/
use Find [Ctrl + F] on page, search for 'System Tray' or just 'Tray' you will find serveral Application that use System tray..
Hope it helops. (slow response due to slow internet speed.....)

Hi,
Does anyone knows how we can retrieve the list of recently accessed documents programmatically
ie enumerate a list containing the file names from Start>Documents
The values are normally stored in the registry in binary format. Any easy way that we can use the information there and present it in CString format?
Thanks in advance, I am very new to all of this.

Thanks.
I think I have found the solution by getting the special folder using CSIDL_RECENT and then reading the contents from that directory.
This seems to work. Any known issues with it?
Also if I wish to read REG_BINARY data from the Recent Docs entry in registry, any idea how I can do that?
Yhanks.

(Obscure question of the month)
What fonts are installed by default with Chinese Windows 2000/XP and other east Asian Windows? (And I do mean the Windows shipped to those countries, not an English Windows using the Chinese, Japanese or Korean fonts.)

Have a gander at the following lines of code:
ofstream intrx;
ofstream intry;
intrx.open("intrx.dat", ios::out);
intry.open("intry.dat", ios::out);
unsigned int l = 0;
for (l = 0; l < m_nNumLines; l++);
{
for (unsigned int k = 0; k < m_nNumVerticies; k++)
{
intrx << setw(12) << m_ppdIntersectionX[l][k];
intry << setw(12) << m_ppdIntersectionY[l][k];
}
intrx << endl;
intry << endl;
}
intrx.close();
intry.close();
Looks innocent enough, yes? It seems there is a *weird* bug occuring here, specifically with the initialization of the loop index, 'l'.
When I trace through the code, I notice that 'l' gets initialized to '37' despite the fact that it is explicitly initialized as '0'.
If I have a look at the following:
&l (gives 37)
&l - 1 (gives 0)
It seems that the value of 'l' is being misplaced
Any help would be appreciated, I can't seem to figure this one out. The project compiles absolutely clean as well...

Errrrrrr, nevermind. I seem to have located it.
for (l = 0; l < m_nNumLines; l++);<---

I *AM* tired.

Do you perhaps call OpenClipboard without closing it?
|
|
|
|

I have no operation about Clipboard. Just after create CRichEditview , Set it Text and formate the Text, the "Paste " operation invalidate.

There are some great articles on this site describing how to go about interfacing with a serial port.
However for a device that we are working on, we need to send 1 byte to the uart at a time (the uart on the recieving end) anytime we choose. not a string. Is this possible to do?
I'm not even closed to advanced in C++ as the majority of you guys are on this site. However if you could give me a push in the right direction or even a sight that gives me a ton of documentation on serial port interfacing and C++ function calls i can use, i'd be very greatful.

Thee have 3 following versions:
1. Write the driver (*.vxd - win98/95/Me; *.sys - W2k/WXP) and ALL problems will be resolved.
2. To use DOS, which one as against windows does not quench the direct reference(reversal) to ports.
3. HANDLE CreateFile(
LPCTSTR lpFileName, // file name
DWORD dwDesiredAccess, // access mode
DWORD dwShareMode, // share mode
LPSECURITY_ATTRIBUTES lpSecurityAttributes, // SD
DWORD dwCreationDisposition, // how to create
DWORD dwFlagsAndAttributes, // file attributes
HANDLE hTemplateFile // handle to template file
);
PS: There is still fourth version - when from a user's mode the functions Native API are invoked
