pButton->EnableWindow(0);

if you have a button control variable called say btn_mybutton;
do this
btn_mybutton.EnableWindow(FALSE); //this will disable it
btn_mybutton.EnableWindow(TRUE); // this will enable it

I have an application that opens a document over dde in winword. Another .Net application can open documents with ODMA(Open Document Management). If i open a document in word with ODMA and i close word, and then i want to open a document from the other application then DDEConnect stops and waits until i close the application that opened the document with ODMA and i start a new word.
It's a bit complicated. Maybe someone has seen a DDEConnect to stop, and wait for something. Why can it be? Please help me!!!

Just wondering how one can determine if a int is even or odd?
Whoever said nothing's impossible never tried slamming a revolving door!
|
|
|
|
|
int i=2;
int j=3;
i%2 = 0
j%3 = 1
You figure out the rest 
Papa
while (TRUE)
Papa.WillLove ( Bebe ) ;

Thanks!

j%3 = 1 ?? j%2 = 1 
Ok, this could be faster,
i&1 = 0 j&1 = 1
but compiler would probably optimize your
solution to this anyway :

I think there was a typo in the other post.
Anyway, mod it with 2 and you'll either get back 1 or 0. For instance:
1 % 2 = 1
2 % 2 = 0
3 % 2 = 1
... and so on. E.g.,
bool IsEven(int j)
{
if(j % 2 == 1)
return false;
else
return true;
}
This could certainly be optimised if high performance is needed... I just posted a simple version.

Hi, I am trying to make an installer for my app. Id like to have all data(files) in one exe file. How should I append or insert these files to my installer application and how to aproach them?
Thanks.
|
|
|
|
|
Instead why dont you import the files as custom resource into your installer, then at installation use the resource handling functions to load and write it to the harddisk.

Thx, but what are these resource handing function?
|
|
|
|
|
To start with...
LoadResource(...);
LockResource(...);
SieofResource(...);
I dont have a sample, try looking for these apis may be you will get one.

You can do it, as the other poster said, by shoving your files into resources in your EXE.
You might be better off getting a commercial package that creates self-extracting ZIP files (I think WinZip can do this but I'm not sure. I know there are others.)

I have 32 bit uncompressed bitmap stored in my application's resources.
I need to load this 32bit bitmap's data for some processing, before it
will be displayed to user.
I'm using GetBitmapBits().
This is working perfectly, but only when my screen is set to display 32 bit colors.
When I switch system's display mode to 16 - bit, this function is not working as expected - it's giving me 16 bit bitmap data.
How to get bitmap's data always in 32 bit ?
Maybe GetDIBits() could do this, but I don't know which DC to use as
first parameter.
Any ideas please ?
Thanks !

Hmm..
Bitmaps are usually selected into a device context, and generally, you create a device context that represents the current display. The best way to alter this behaviour is to manually create a DC large enough to hold your bitmap, and with the correct color depth. Then, you can select this bitmap into a device context and use the device context's functions to retrieve the color of each pixel. The problem with GetBitmapBits is that it creates a screen-compatible DC to which the bitmap is selected, and bases it's results into the return values of pixel query on the DC surface. Thus, if the DC is set to 16-bit depth, the resulting bit array consists of 16-bit data.
I'm not sure, but the DC parameter of GetDIBits represents a device context into which the device dependant bitmap is to be selected. The best way to proceed would be to create arbitary device contextes with different color depths, and see how the resulting bitmap bits vary.
The easiest way, of course, is to force the display to 32-bit depth before doing the loading: just put a 32-bit screen depth as a prerequisite for your application.

Thanks for answer,
but application must run also on 256 color displays,
The problem is that I don't know how to create 32 bit DC manually,
without 32 bit display colors. Maybe it's not possible.
In worst case I'll have to store bitmap data as raw data in resources

Hi,
does anyone know of debuggers available which were programmed using MFC's. It would be of some use as I need to know how to display a disassembly file
Kind regards

let me put the question diferently.
I've an assembly file and I want to display the disassembly file of this to a mfc application. How would this be done??

Get the manual for instruction set fromthe www.intel.com site for the processor and decode the opcode the way you want to.

Is there a function or code to lock my computer,like this: you need a password to enter in application to enable using computer.The program should lok all functions of computer,and it should be turned off only by password!
Thanx
|
|
|
|
|
LockWorkStation();
Don't try it, just do it! 
|
|
|
|
|
Just use a password-enabled screen saver. To enable it programmatically, check out the following value in the registry:
HKEY_CURRENT_USER\Control Panel\Desktop\ScreenSaverIsSecure
The alternative, LockWorkStation(), only works on Windows 2000 and newer machines.

Hi all,
I have client application and server application (FTP server / client). On client side, due to certain reasons, I use CArchive to write / read data to / from socket. On the server side I use CSockets to send / receive data.
It worked fine for me, but now I implemented encrypted communication (Twofish cipher) and want to exchange the data safely. When I send encrypted data from client to server (ie. CArchive::Write()), it is ok. But when I use CSocket::Send() to send encrypted data from server to client, on client side the call of CArchive::Read() doesn't return and after a while it throws CFileException (OS Error it says).
My method for sending encrypted data from server to client is the following:
[CODE]
DWORD dwToAllocate = CTwofishCipher::getPaddedSize(strlen(s) + 3) + TC_BLOCK_HEADER_SIZE;
BYTE* encryptedData = new BYTE[dwToAllocate];
memset(encryptedData, 0x00, dwToAllocate);
encryptAnswer(stringToSend, encryptedData);
pControlSocket->sendEncryptedString(encryptedData, dwToAllocate);
void CMyControlSocket::sendEncryptedString(BYTE* encryptedData, INT dataLen)
{
CSocket::Send(encryptedData, dataLen, 0);
}
[/CODE]
And the code of client for receive encrypted data is here:
[CODE]
BYTE* receivedData = NULL;
UINT nBytesRead = 0;
TRY
{
receivedData = (BYTE *) m_retmsg.GetBuffer(32000);
nBytesRead = m_pCtrlRxarch->Read((TCHAR*) receivedData, 32000);
m_retmsg.ReleaseBuffer();
}
CATCH(CFileException ,e)
{
ErrorCode = e->m_lOsError;
return FALSE;
}
END_CATCH
[/CODE]
The interesting is that when I check received data on client side (after it throws the exception after a while), the bytes received exactly match the bytes which had been sent. Anyway, the function CArchive::Read() has apparently some difficulty receiving the buffer.
Thanks for any suggestion!
