WM_INITDIALOG happens when the dialog is about to inialize. i have a function that i want to run after the dialog is inialized.

I"m not sure about this, but

BOOL m_bFirstPass;

CDialog:CDialog()
{
  m_bFirstPass = FALSE;
}

CDialog::OnInitDialog()
{
  m_bFirstPass = TRUE;
}
 
CDialog::OnActivate()
{
  if(m_bFirstPass == TRUE)
    //Execute code only on first call
    m_bFirstPass = FALSE;  //Prevent from code being    executed again
}

This might work! Smile | :)

Adding Message Handler in MFC with Visual C++ 7.0

6-Apr-02 2:29

Hi
We have a problem adding message handling functions for Non Dialog Controls in MFC with Visual C++ 7.0.
We cant find a way to do this the easy way. The Class Wizard which existed under 6.0 doesn't exist here, and thru the events in the properties of a class only menu and accelarator IDs are accessible. None of the Buttons from a Toolbar for example is available.

Thanks
Lars

Well, first of all, in most cases where you have toolbar buttons, you should also have a corresponding menu item, or at least an accelerator. In these cases, the Events property sheet will work. If you absolutely cannot have a menu or accelerator for your button, it is trivial to add the message map entry manually:

ON_COMMAND(Command ID of button, Handler function)

trapping GDI objects

Is there any way GDi objects can be trapped,ie Images of the application.At the operating system level,Probably Input output request packet(irp) form the gdi objects,but that would involve hooking the kernel....

Thanks for spending time...

You can try API Capture. Someone just posted an article on this topic. With this technique you could trap all of the GDI calls from a particular app, change the calls, or just spy on them, it up to you.

TCI/IP in C#

Nick Parker6-Apr-02 2:01

I know this is the C++ forum, however it was the suggestion of another to post this question here. Suppose someone were writing a "firewall" application that was "watching" or listening for activity over an incoming IP address, what is the best way to cover all ports. In all the examples I have read, someone creates an instance of TcpListener and supplies a port to listen to. Surely you don't have to do that for each of the 65,000+ ports. Could someone lead me in the right direction. I am going to do this in C#, Thanks in advance. Confused | :confused:

OS only uses a predefined number of ports ..even there is more than 64000,like HTTP(80),FTP(21 i think...not sure ) such like...

Problem with htonl() function!!!

5-Apr-02 23:53

Hi,

I use the htonl() fonction to convert an IP address from "host byte order" to "network byte order" but it does not work, or sometimes it work and sometimes not!!!.
here is the portion of code that i used to display the IP address :

in_addr addr;ip = htonl(ip);// ip is an u_long already initialized
addr.S_un.S_addr = ip;char* dst = inet_ntoa(addr);AfxMessageBox(dst);

what is going wrong ?

if (InitialiseSocket(wsaData))
{
gethostname(szHostName,256);
pHP = gethostbyname(szHostName);
memcpy((char FAR *)&(myaddr.sin_addr), pHP->h_addr,pHP->h_length);
wsprintf(szIpAddress,"%d.%d.%d.%d",myaddr.sin_addr.S_un.S_un_b.s_b1,myaddr.sin_addr.S_un.S_un_b.s_b2,myaddr.sin_addr.S_un.S_un_b.s_b3,myaddr.sin_addr.S_un.S_un_b.s_b4);

The snipit of program below should create a table 25*25 with the alphabet in each row(in theory i think.
Dose any body know how i can use that table? i basically want to compare a word entered with that table. But cant seem to do this.
Any code will be very helpful

void CFinal3Dlg::OnBeta()
{
radio_select=2;
//create table
for (row= 0; row<=25; row++)
{
ch='A'+row;
for (col=0; col<=25 ; col++)
{
ch++;
if (ch>'z') ch = 'A';
}
}
// compare entered data with table
{

How do you want to compare a word ? This sounds like a solution looking for a problem to me.

if you want to compare words you can use strcmp for char type. if you are using cstrings, they have a compare function built-in. note though they are case sensitive.

MSVCRT.DLL problem !

Hi there,
I wrote program by VC++ 6.0 on WinXP, and i made the setup disk by InstallShield ...
InstallShield added MFC42.DLL and MSVCRT.DLL to setup project !
When i run the setup disk on Win98SE, Win98SE crashes !!!
And Win98SE shows me error about MSVCRT.DLL error and something about NTDLL.DLL
(Now, i have to re-install Win98)
Hmmm, well i have reply for myself, WinXP is NT based and Win98 is not !
and the MSVCRT.DLL in WinXP is the main reason !

In fact i need the Setup disk for Win2000 Pro ...
I wanna know, Is there any problem later, If i run my setup program on this OS ?
By the way, what is exactly MSVCRT.DLL ?

Please reply about my main question that was about running the setup disk on Win2000 ...
And if you have time, please write some points about making setup disks ...

Thank you very much !

It's the C Runtime. You need, I believe, to install a different one for 9x and for NT based OS's.

Is this Possible???

Hi,
I wonder wether it's possible to launch/open an application from my Win32 application and identify when it's closed. I used ShellExecute to open another application from my Win32 application. But, I don't have any control over the newly opened process. So Is there any way to know when newly opened application closes? will CreateProcess() and EnumProcess() API functions any way useful for this? I'll be thankful for any suggestions.

thanks for spending time

Re: Is this Possible???

Both CreateProcess() and ShellExecuteEx() return a handle to the new process. Use that handle in a call to WaitFOrSingleObject(). That API will unblock when the process ends.

Question about OnNewDocument()

Nish Nishant5-Apr-02 18:48

5-Apr-02 18:48

Hello guys

I haven't done too much doc/view stuff before and am now stuck with some doc/view stuff [elementary]

I have some member objects in my CDocument class.

And in my CView class's OnUpdate I use these objects to render my view.

Now my problem is that when I take New from the toolbar or the menu I expect my entire CDocument object to be destroyed and re-instantiated. But to my utmost disappointment I find that this is not so.

Now I have only one option as far as I see :-

In my CDocument's OnNewDocument()

I must manually clean up all the CDocument member objects.

Is this the right way?
Or am I worse than bugs bunny when it comes to doc/view?

Any help is hugely appreciated.

Warm regards
