Because you are trying to access a non-existent window. Once DoModal() returns, any windows it owned are destroyed.

A task infront of me is to develop local chat server
which will just accept data from everyone and pass it to person whom it is to be send.
Server compiles fine but as soon as I run it ,it fails. Errors come at Accept statement.
The requirement is due to internet is not allowed.
And way for instant communication is required as comapany
layout is very complecated to reach from one room to other. Official mail is too inconvenient for small messages.

Dear all,
i have been requested to post my question on C here.Thanks
Here is my problem:
Am doing some analysis on RC4 TKIP.I want to create an RC4 key and XOR it with data.My RC4 key is Ok.But i want to pass it as a parameter so as to do encryption.
Can anyone among you help,as i have the RC4 keys in an array.But i want to pass this result in the second part of my program so as to do encryption with that key.
kind regards and thanks
NB
rc4key[0] = tsc2 % 256; <br />
rc4key[1] = (((tsc2 / 256) % 256) | 0x20) & 0x7f;<br />
rc4key[2] = (tsc2 / 256) % 256; <br />
rc4key[3] = ((ppk5 ^ ((256*key[1]) + key[0])) >> 1) % 256;<br />
<br />
rc4key[4] = ppk0 % 256;<br />
rc4key[5] = (ppk0 / 256) % 256;<br />
<br />
rc4key[6] = ppk1 % 256;<br />
rc4key[7] = (ppk1 / 256) % 256;<br />
<br />
rc4key[8] = ppk2 % 256;<br />
rc4key[9] = (ppk2 / 256) % 256;<br />
<br />
rc4key[10] = ppk3 % 256;<br />
rc4key[11] = (ppk3 / 256) % 256;<br />
<br />
rc4key[12] = ppk4 % 256;<br />
rc4key[13] = (ppk4 / 256) % 256;<br />
<br />
rc4key[14] = ppk5 % 256;<br />
rc4key[15] = (ppk5 / 256) % 256;<br />
void rc4(<br />
unsigned char *rc4key,<br />
<br />
int cipherstream_length,<br />
unsigned char *cipherstream<br />
);<br />
void rc4_encrypt(<br />
unsigned char *rc4key,<br />
<br />
unsigned char *data,<br />
int data_length,<br />
unsigned char *ciphertext<br />
);<br />
<br />
these are the codes, I wanted to use the result in the array above and used it as a pointer!!!
am nt getting any syntax error..but isthere any logical error?
please advice.
nb

If rc4key is an unsigned char array, then just pass rc4key, which is the same as &rc4key[0].
What is the line(s) of code you're getting syntax error on?

Hi,
I want to dock the views in my MFC Application that means views can be drag and drop from one place of my frame area to other.How can it possible? Please help me
ganesh

I dotn know about Views but you can dock dialogs using CDialogBar
which View types you wanna make docable??

I want to dock the views which are derived from CView.

i am in need of how to add the checkbox image to the header of a CListCtrl i have a child dialog in the main dialog ive looked in msdn but im lost
CImageList * imagelist;<br />
CHeaderCtrl * m_pHdrCtrl;<br />
imagelist = new CImageList();<br />
ASSERT(imagelist != NULL);<br />
imagelist->Create(13, 13, ILC_COLOR24, 3, 1);<br />
CBitmap bm;<br />
bm.LoadBitmap(IDB_CHECKBOXES);<br />
imagelist->Add(&bm, RGB(255, 0, 255));<br />
m_pHdrCtrl->SetImageList(imagelist);
that gives no errors on compiling it
m_pHdrCtrl->SetImageList(imagelist); <-- wont allow me to build the exe
im a beginner be gentle when telling me how wrong it is  i cant figure out how to add the imagelist to the header.

What do you mean? After puttin the above statement your not getting the output exe?
|
|
|
|
|
|
now only i noticed you are not assigning any thing in to the CHeaderCtrl * m_pHdrCtrl;
you must call the GetHeaderCtrl() function and set that pointer to the m_pHdrCtrl. like
CHeaderCtrl * m_pHdrCtrl = m_ListCTrl.GetHeaderCtrl();
|
|
|
|
|
|
Hi,
if this is the code you wrote it cannot work. You declared a pointer to CHeaderCtrl and some lines below you access this pointer which you never set. This code compiles fine but certainly it results in a crash! You have to ask your CListCtrl instance for the pointer to its header control...
Try the following:
CHeaderCtrl* m_pHdrCtrl = m_YourListCtrl.GetHeaderCtrl();
if(m_pHdrCtrl != NULL)
{
CImageList * imagelist;
imagelist = new CImageList();
ASSERT(imagelist != NULL);
imagelist->Create(13, 13, ILC_COLOR24, 3, 1);
CBitmap bm;
bm.LoadBitmap(IDB_CHECKBOXES);
imagelist->Add(&bm, RGB(255, 0, 255));
m_pHdrCtrl->SetImageList(imagelist);
}
cheers,

Hi,
Is it possible to have multiple thumbs along a slider control, if so can anyone direct me as to where I can find informantion on how to do this..
Thanks in advance!
Stefan.

Please let me know How we can get the size of CPU cache?
and how can er read and write CPU cache using MFC?

Hi
Use xtreme toolkit can add a outlookbar to single doucment easily;
but I don't know how to add a outlookbar to multipe document?
how to do that?
could you give me a code?
Thanks!

Hi Everyone,
I'm writing an application that implements an on-screen keyboard (because the Windows on-screen keyboard is extremely small and hard to use) and I'm having problems setting focus to the desired window in which the user wishes to type.
I'm using a few User32 API calls to get the active window handle number and then set the active window once I know what the handle is. This seems to be working OK. However, the window which has focus (the one receiving the typing) flickers as the user clicks on a key.
This is because as the user touches a key to type, it gives the keyboard focus and then immediately sends focus back to the window in which the user is typing, hence the flickering. So...
Question #1:
How can I eliminate the change of focus and always give focus to the desired window so that there is no flickering back and forth between my keyboard application and the window receiving the typing?
Question #2:
This is not just a standalone keyboard, but is a small part of a larger piece of software. Consequently, there are occasions when the user must use this on-screen keyboard to type into a window within it's parent application or into different forms within the app. One form contains a browser control to a company website. When they keyboard is used to type into any text field on a webpage displayed in the browser control, only every other word is sent to that text box. Two key strokes are required to output one letter. What could be a possible cause of this and how might I go about fixing it?
ANY suggestions or help is much appreciated. Code examples in VB.NET, VB 2005, and C# are fine. C++ OK too but only if it's immediately applicable and can be converted easily to VB.NET.
Thanks in advance to anyone who contributes!!!!
Patrick

Have you tried keeping the active window as your onscreen keyboard, and using SendMessage or PostMessage with WM_KEYDOWN or WM_CHAR to send the appropriate keystrokes to the target window? Or SendInput?
VB.NET, what is that?

Steve,
Thanks for the reply. I haven't tried that so I'll do some research today and give it a shot. Thank you much!

Hello,
BYTE pdest;
pdest += sizeof(DLGITEMTEMPLATE);
*(WORD*)pdest = 0xFFFF; // indicating atom value
pdest += sizeof(WORD);
*(WORD*)pdest = (USHORT)m_eTypeControl; // atom value for the control
pdest += sizeof(WORD);
Can you please explain me the syntax of the above code or give me the link
What does *(WORD*)pdest = 0xFFFF; mean ?
Thanks

(WORD*) casts the BYTE pointer to a WORD pointer.
The '*' before the cast dereferences the WORD pointer so the "= 0xFFFF" can place a WORD value
at the location pointed to by pdest.
It ends up being the same as:
BYTE pdest;
pdest += sizeof(DLGITEMTEMPLATE);
WORD *pdestWORD = (WORD *)pdest;
*pdestWORD = 0xFFFF; // or pdestWORD[0] = 0xFFFF; // indicating atom value
pdest += sizeof(WORD);
pdestWORD = (WORD *)pdest;
*pdestWORD = 0xFFFF; // or pdestWORD[0] = 0xFFFF; // atom value for the control
pdest += sizeof(WORD);

Hello,
That makes for a wonderful explanation but what exactly is atom value.
atom value is character represented in the character set.
pdestWORD[0] = 0xFFFF;.
so is the above statement placing FFFF in the 0th position of pdestWORD .That is the corresponding code of FFFF.
What does DWORD aligned mean?

Atoms are described here[^].
BYTE pdest;
pdest += sizeof(DLGITEMTEMPLATE);
*(WORD*)pdest = 0xFFFF; // indicating atom value
pdest += sizeof(WORD);
*(WORD*)pdest = (USHORT)m_eTypeControl; // atom value for the control
pdest += sizeof(WORD);
In your case, if the WORD following a DLGITEMTEMPLATE struct is 0xFFFF then the next WORD is an
atom representing the class name of a control. The 0xFFFF is just an indicator to differentiate
between a Unicode string (which could be used instead) and an atom.
