If the control ID you pass to CWnd::GetDlgItem() references an edit control, then you can just cast the return value to a pointer to a CEdit. This works with any other type of control also.

Save yourself some aggravation and use a CEdit member variable instead.

I think what you are looking for is a splash screen. Try searching splash screen in codeproject. It is by the way not difficult to write your own.

such as :extern CDatabase db;
CString sql1,sql2;
....
sql1=" ....";
db.ExecuteSQL(sql);
.....
sql2="...";
db.ExecuteSQL(sql);
....
|
|

|

You can call as many ExecuteSQL statements as you like given that the sql is a valid sql statement.

Hello All, I have client and server programs. They used NamedPipe to communicate.
Here little bit about what each program does.
Server:
- has 2 buttons, print and stop
- Once the print button get pressed, create the thread and call the thread function.
here the thread function,
<br />
UINT PrintingThreadFunction(LPVOID lParam)<br />
{ <br />
CServerDlg *s = ((CServerDlg *)lParam);<br />
s->m_smain.OpenNewPipe(); <br />
while(!stopprinting)<br />
{ <br />
s->m_smain.ClientPrinting();
if(stopprinting == (int)YES)<br />
{<br />
s->m_smain.CloseThePipe(); <br />
break;<br />
}<br />
} <br />
stopprinting = (int)NO;
return (0);<br />
}<br />
The ClientPrinting() calls ConnectNamedPipe() which waits for the client to connect and then once the client connect to the pipe, it returns.
Client:
Client gets the file name from database and print it out. Then send the file name to Server using the same pipe.
Server has no problem Client's getting connected and sending a printed file name for 9 times. But at 10th time, Server get error message at ConnectNamePipe() which is
Unhandled exception at 0x0043e4cb in Server.exe: 0xC0000005: Access violation reading location 0x000000e4.
How can I eliminate this error?
I am thinking of using PostMessage(). But how the program also listen to the user click on Stop button?
Is stopping what the programs is doing for 10 seconds so the user can click on the quit button will help?
Thank you

Not sure of what the "stopprinting" is but would suggest to use event instead like this
<br />
if(WaitForSingleObject(<br />
yourStopEventHandle,<br />
INFINITE<br />
)== WAIT_OBJECT_0)<br />
{<br />
}<br />
check the event tutorial avail.

Having trouble getting this to work.
Need to control backlight level of LCD display.
Followed instructions for IOCTL_VIDEO_QUERY_SUPPORTED_BRIGHTNESS and not getting any errors, but not getting any 'levels' back either.
Has anyone else tried using this API yet?

long value = pow(long1, long2) % long3;
you need to include <math.h>

MSDN says: The modulus operator (%) has a stricter requirement in that its operands must be of integral type.
just cast the pow() function to a (long)

Try this...
long value = ((long)pow(long1, long2)) % long3;

I suggest you do it manually with repeated multiplings and the apply the modulus

I am creating a small application that is going to run on a network. I need to know the number of people that are running the application on the network. I had tried looking for an example on how to this but I can’t find any. Any help!!!

When the application is started, you could simply write a "counter" number to some file. There are obviously lots of implications in doing this, but it is simple.

HMODULE hm = LoadLibrary("http://some.server.net/downloads/a.dll");
Of course I know that the above does not work. Implementing the HTTP part is no problem, but how do I simulate LoadLibrary without an actual file?
(storing the downloaded DLL in a temporary file is not an option, I want real "zero footprint")
