how to disable printscreen key when my program is running and enable printscreen key when my program closed?

Dunno if it's possible!
But you can make a hook and catch when printcreen button is pressed and then remove the content.

I would add my program to the clipboard notifier chain (SetClipboardViewer) and wait until the clipboard changes (you receive a WM_DRAWCLIPBOARD).
When the clipboard changes, check immediately if the Print Screen Key is pressed (GetAsyncKeyState) and if it is, clear the clipboard (OpenClipboard, EmptyClipboard, CloseClipboard).

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

1. Create a DLL that holds a System Wide Keyboard Hook.
2. Start the hook at the beggining of your program.
3. stop the hook when you want it...
NOTE 1:
you can also receive a notification from that DLL that the event has happened via a WM_XXX or whatever other method...
NOTE 2:
If you want to avoid the printscreen press only when your app has the focus you could avoid the system wide hook and hook only your app.
hope this helps.

I have a class with members that are pointers to the base class of derived classes... Here's a simplified example.
class CDerivedClass : public CBaseClass
{
DECLARE_SERIAL(CDerivedClass)
int something;
}
class CBaseClass : public CObject
{
DECLARE_SERIAL(CBaseClass)
...
void Serialize(CArchive &ar);
...
(data to archive)
}
class CCompoundClass : public CObject
{
DECLARE_SERIAL(CCompountClass)
...
void Serialize(CArchive &ar);
...
CBaseClass *ptrBaseClass; // points to the CDerivedClass
}
I dynamically allocate CDerivedClass, and set the CBaseClass pointer in the CCompoundClass to this object. I want to make the CCompoundClass Serializable, but don't seem to have the right recipe to pick up the derived class that ptrBaseClass points to. Any suggestions?
I read through the help documentation, but it doesn't cover this case.

I should have submitted this earlier... After scratching my head for a few hours, I deleted the object files (clean), rebuilt, and everything worked as expected.

Hi all,
I am connecting to sybase through my VC 6.0 DLL which gets called from PB
application, its is multithreaded DLL. I am using ODBC to connect sybase. I
am facing some major problems. I am connecting to (Ora, Syb, SQL) through
this sam DLL with ODBC.
The problems which i am facing is
1) Sybase not allowing to use Dynaset in recordset. if i use forwardonly it
works but not allows me to go back.
2) When this thread is ended, system gets hanged.
Although the same code is running perfectly with ORA,SQL server.
I am looking forward for some general way which will be applicable for all the databases.
Thanks
Ajaz

Hello, anyone knows hot to configure the Soap Trace Utility that comes along with the SOAP SDK 3.0.
I encounter difficulty in configuring it to trace .ASPX page.
In the help file. it stated
In the WSDL file, locate the <soap:address> element that corresponds to the service and change the location attribute for this element to port 8080. For example, if the location attribute specifies <http: myserver="" vdir="" service.wsdl=""> change this attribute to <http: myserver:8080="" vdir="" service.wsdl="">.
But, there is not WSDL file for a .ASPX file. The WSDL document is generated runtime by the .NET when passing the query string as http://localhost/test.aspx?WSDL
How to confgure it to the WSDL file? I need to trace the content of the SOAP communication between client and server.
Thank you.

I thought out already.
it is by passing the URL as http://localhost:8080/sss.aspx.wsdl

Does anyone know how to map frequency ranges to the bands of an equalizer??? I'm trying to map the 20hz to 20kz range to a 32-band equalizer. But the relation is not linear...

How come I get the following errors on my MFC dialog app? I have included fstream.h and I have used code like this before. Why is it not working here?
void CTestDlg::OnTimer(UINT nIDEvent)
{
fstream file;
file.open("Run.txt", ios::out);
CDialog::OnTimer(nIDEvent);
} </code>
error C2065: 'fstream' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'file'
error C2065: 'file' : undeclared identifier
error C2228: left of '.open' must have class/struct/union type
error C2653: 'ios' : is not a class or namespace name
error C2065: 'out' : undeclared identifier
Error executing cl.exe.
Thanks,

If you have a problem with my spelling, just remember that's not my fault. I (as well as everyone else who learned to spell after 1976) blame it on Robert A. Kolpek for U.S. Patent 4,136,395.

it's:
ifstream file
or
ofstream file
if that doesn't work, try:
std:: (file == input ? i : o)fstream;

Hi Nitron.
I've already tried the ofstream (it's output), but with no success. I just tried your "if that doesn't work" also with no success. I got the following errors (*note* I copied your code exactly):
error C2653: 'std' : is not a class or namespace name
error C2589: '(' : illegal token on right side of '::'
error C2143: syntax error : missing ';' before '::'
Error executing cl.exe.
I've had my previous way work before, but without using MFC. Any ideas?

You neet to include:
#include "fstream.h"
and try:
std::ifstream file;
(my last line was pseudo-code, telling you to put "i" or "o" depending on if it's an input file or not. Sorry

you are probably doing this:
#include <fstream.h>
#include "stdafx.h"
try this:
#include "stdafx.h"
#include <fstream.h>

Wow! Thanks! That fixed it! I know the order of headers matters, but is there a simple reason why this worked?
Thanks,

The compiler uses stdafx.cpp to generate a precompiled header file substituting it for all # include's in the # include stdafx.h directive. The header stdafx.h should be at the top of all headers because the compiler ignores any # include directives before stdafx.h.
// Afterall I realized that even my comment lines have bugs
|
|
|
|
|
if you don't want to include stdafx.h try this:
go to Project->Settings->C/C++->Project Options and search for:
""/Yu"stdafx.h"" and replace it by "" (nothing)  (that means kick it !)
and you don't need to include stdafx.h

hi people,
I created a button (button1) that was suppose to bring out the save file dialog and prompt user for a place to save the file.. which works exactly like "SAVE AS" under FILE selection. but i can't get it to work. for example, i want to save a file "c:\ABC.txt" into "d:\XYZ.txt" using the save file dialog once button1 is clicked...
void CMytestDlg::OnButton1()
{
}
thanks in advance.;)

.... the dialog thing came out.. but it looks like a file opening dialog.. i'm really new at this... can you please be more detail here? thanks..
for example..
everytime button is clicked.. a specific file (c:\ABC.txt) will be saved to another location that user placed in the prompt..
thanks again.. your help is grealy appreciated..
|

there is a member of CFileDialog called
m_ofn[^].
it is an OPENFILENAME[^] structure, which can be modified before calling the dialog (ie. before DoModal()) to define the dialogs behaviour.

Use CFileDialog dlg(FALSE); instead - this creates the dialog as a "Save" dialog instead of an "Open" dialog.

oops.
