to get a dialog bar to work correctly you have to use the CMainFrame class and not a class of its own.
To use CtabCtlr in a normal dialog you create the tabs in WM_INITDIALOG. You cannot derive WM_INIDIALOG from CMainFrame.
I am not sure which handler to use, in this case
Is there an equivalent to WM_INITDIALOG for CMainFrame??

Ah. You could post a custom message (IDC_INIT_TABCTRL) to the dialog bar the first time it's shown, and initialize the tab control in the handler for IDC_INIT_TABCTRL.

thankyou

I think my earlier response was sorta misleading (I'm not fully awake). Just override your dialog bar's OnShowWindow() and add this logic to it (after calling the base class handler):
if (!m_bTabCtrlInitialized) {
...;
m_bTabCtrlInitialized = true;
}
m_bTabCtrlInitialized is a bool member that's initialized to false in your dialog bar's constructor.

i also cannot create a member variable for the tab control in CMainFrame. How do i go about doing that?
thankyou

The tab control is a member of the dialog bar, not the mainframe. The mainframe is a container window and isn't associated with a dialog resource.

I want to get bytes sent and bytes received in windows 2000, I try to use IP Helper API GetIfEntry, but it seems that the bytes sent and bytes received data is changing slowly, and another problem is the bytes sent is equal to bytes received.
Would you please tell me how to fix this problem?
Thank you very much!
The program is as the following:
int _tmain(int argc, _TCHAR* argv[])
{
cout<<"net adapters information:"<<endl<<endl;
="" pmib_ifrow="" ifrow="new" mib_if;
="" mib_ifrow="" ifrow;
="" mib_ifrow();
="" for(int="" i="1;i<2;i++)
" {
="" ifrow-="">dwIndex=i;
DWORD dret=GetIfEntry(ifrow);
if(dret!=NO_ERROR)
{
//cout<<"error index="<

The Programme FTPWander(http://www.codeproject.com/internet/ftpwanderer.asp)
implement the transmission using WININET API.But as MSDN issued, CInternetFile don't Support CInternetFile::Seek(..)
for FTP File, then I just don't know how to implement resuming interrpted transmission when using WININET API.
thanks for any ideas

I had developed a service that run under win2k, this service uses those functions in order to prevent the user to use the keys involved, but for my surprise it only works in some computers...
The fact is that I cannot use it in an industrial PC as I would do in a normal home PC.
take a look at those functions:
<br />
<br />
DLLSCT_API bool bActivarHook(bool bActivar )<br />
{<br />
if(bActivar == true)<br />
{<br />
hHookTeclat = SetWindowsHookEx(WH_KEYBOARD_LL, HookTeclatLL, hInstDLLSCT, NULL);<br />
return (hHookTeclat != NULL);<br />
}<br />
else<br />
{<br />
if(hHookTeclat != NULL)<br />
{<br />
UnhookWindowsHookEx(hHookTeclat);<br />
return true;<br />
}<br />
else<br />
{<br />
return false;<br />
}<br />
}<br />
}<br />
<br />
<br />
static LRESULT CALLBACK HookTeclatLL(int nCode,WPARAM wParam,LPARAM lParam)<br />
{<br />
if (nCode == HC_ACTION)<br />
{<br />
switch (nCode)<br />
{<br />
case WM_KEYDOWN:<br />
case WM_SYSKEYDOWN:<br />
case WM_KEYUP:<br />
case WM_SYSKEYUP:<br />
{<br />
LPKBDLLHOOKSTRUCT p = (LPKBDLLHOOKSTRUCT)lParam;<br />
bool bEliminarPressioTecla = false;<br />
<br />
if ((p->flags & LLKHF_ALTDOWN) != 0)<br />
{<br />
bEliminarPressioTecla = (p->vkCode == VK_TAB) || <br />
(p->vkCode == VK_ESCAPE) ||<br />
(p->vkCode == VK_F4) ||<br />
(p->vkCode == VK_LWIN) ||<br />
(p->vkCode == VK_RWIN);<br />
}<br />
else if ((GetKeyState(VK_CONTROL) & 0x8000) != 0)<br />
{<br />
bEliminarPressioTecla = (p->vkCode == VK_ESCAPE) || <br />
(p->vkCode == VK_F4) ||<br />
(p->vkCode == VK_LWIN) ||<br />
(p->vkCode == VK_RWIN);<br />
}<br />
else<br />
{<br />
bEliminarPressioTecla = (p->vkCode == VK_LWIN) ||<br />
(p->vkCode == VK_RWIN) ||<br />
(p->vkCode == VK_ESCAPE);<br />
}<br />
<br />
if (bEliminarPressioTecla) <br />
{<br />
return 1;<br />
}<br />
<br />
break;<br />
}<br />
}<br />
}<br />
<br />
return CallNextHookEx(hHookTeclat, nCode, wParam, lParam);<br />
}<br />
when I start windows by default I start that service automatically.
but it don't prevent those keystrokes in the industrial PC that I'm using now...
I will contact my supplier in order to know which differences are between that industrial PC and the "normal" ones, but as far as I can see the only difference is that it need to be configured as an american keyboard...
Is there any way in which I can see which key is being pressed, or somewhere where I can find information related (keyscan codes...)
As always thank you very much...

i have buy many books about MFC.. but i can't find helpFULL information in them ...
maybe somebody knows any GOOD links/ttorials about MDI framework programming,
what i can simply download them and study at home ... !?!?
PS: it's better if it wont be about document/view ....
PPS : it is not enoughtwith examples on codeguru codeproject :P
PPPS: sory for my ENG...

I use the T2CA() macro to convert a string (UNICODE or non UNICODE - the code should work with both systems) to a char* string (each character = 1 byte) to save it to a file.
The code looks like:
...
USES_CONVERSION;
DWORD dwWrittenBytes;
if (!WriteFile(m_hFile, T2CA((LPCTSTR) str), str.GetLength(), &dwWrittenBytes, NULL) ||
dwWrittenBytes != (DWORD) str.GetLength())
{
...
}
...
The problem is that when I have a string like "Büro" (a german word), the T2CA() macro removes the "ü" in the string and saves the string "Bro" to the file!
So, how can I convert a string (UNICODE / non UNICODE) to a char* without removing some characters (like ü,ö,...)?

The following works just fine for me:
#include <atlbase.h>
#include <iostream>
#include <fstream>
using namespace std;
int main(void)
{
USES_CONVERSION;
ofstream ofs("out.txt");
ofs<<W2CA(L"Büro")<<endl;
return 0;
}Maybe the problem is in the third parameter of the call to WriteFile. Shouldn't it be str.GetLength()*sizeof(TCHAR)?
Correction: This is obviously not the problem, since you're writing ANSI strings.

Yes! This is not the problem! It's just a problem of the conversion (UNICODE -> ANSI)!
Please take a look on my reply to the message of Maximilien Re: UNICODE problem!.
Thanks!!!

Why can't you just save the UNICODE string ? why the conversion ? WriteFile writes a void buffer, just just need to set the lenght correctly ( as stated by the other poster )
Max.

Because, when I write the UNICODE string to file, every character is 2 byte wide! So, when I reload the file on a other system (application - non UNICODE), the system (application) sees the string wrong, because it means, that there is a simple char* string in the file and no UNICODE (2 byte) string!
Example:
- My PocketPC application (UNICODE) writes some measurement data in a ASCII file.
- I load the measure data file on my desktop pc (non UNICODE).
So, that I can use the same source code on both systems (PocketPC & PC) I write the measure data in simple ASCII form (1 byte) in a file! So, both system can load and store the measure data!

My question is how is that we are able to use both the ways
Can anyone answer me please ?????

why is it overloaded when one way can server the purpose ?

Anyone willing to tell me how to restore the unicode build option in the active confiuration for VS6? Hoping it will be quicker to ask here then go back to the office and get my books.
Thanks

Menu Build -> Set Active configuration -> Unicode

That was I had thought I would need to do when I removed it from the build on the project I needed from. However, the only options I have to choose from in the Build-> Set Active Configuration are Win32-Release and Win32 Debug. Any idea how to get that (the unicode build) option back into the Active configuration? I have also looked for it in
Build->Configurations... but did not find it there to be added.

I have an MDI application with 2 views . One is the default one created by AppWizard (which is a FormView ) and the other one was which I added to the framework ( A CtreeVIew) .
I am able to get a print preview for the First View but not for the Second View . Why ?
What should i be doing to get a print preview for the other view too ?
Some insight into this would be appreciated .
