I had the same problem. For that I made a service, that test the applications that are running. If I detect that one application of my list is killed, I restart again, the application. didn't find another solution...

Hi,

I´ve seen that some apps, like Babylon, can trap a key, or combination of events ( shift + right mouse), even if the application has not the focus.

How can be this thing done ?

Thanks, Bye !

Use EnumChildWindows to get all the child windows of that dialog.

Once you find your edit control use GetDlgItemText to get the text on it

.NET Confusion

Hello,

I am new to .NET and have some questions.

1. What is the differenes between .NET Framework SDK and Visual Studio?

2. I am currently learning standard ansi c++, and I am wondering whether I should learn VC++ 6 or VC++ 7 next.

3. If I were to take the VC++ 6 Desktop Apps Certification exam would it be worth it or wait for Vc++ 7.

4. Is VC++ 7 compaitable with ANSI C++?

5. Who here actually likes Visual studio 7 or .NET ?

thanks,
vinuk

1. The framework SDK is a set of classes/functions to program for the .NET environment. Visual Studio is just an integrated development environment.

2. Sure. Go ahead.

3. Not sure about that.

4. Not fully Smile | :)

5. Most people including me.

Visual Studio is an Integrated Development Environment (editor, debugger, wizards, etc..) that also includes compilers for various languages.

.NET Framwork SDK is simply a software development kit. It doesn't include an IDE or any of that stuff.

VC7 is more standard compliant than VC6, but it's still not 100% and is missing a few key (but advanced) features.

Chances are, there won't be a VC7 certification for a while yet... so you might as well take the vc6 ones.

VC7 rocks.

Visual Studio is an IDE, while .NET Framework SDK is a development kit. You can make .NET programs without VS, but not without SDK.

There is not such a big difference between VC6 and VC7, if you don't count Managed C++.

I think you should wait for Vc++7.

inp() and outp() won't work on NT ?!!!

Please read below article ...
It mean i can't use inp and outp on NT ?
So, what i can use instead inp() and outp() functions ?

Help me ! Frown | :(

DOC: Port I/O with inp() and outp() Fails on Windows NT
ID: Q112298

--------------------------------------------------------------------------------
The information in this article applies to:

The C Run-Time (CRT), included with:
Microsoft Visual C++, 32-bit Editions, versions 1.0, 2.0

--------------------------------------------------------------------------------

SUMMARY
Attempting to use the port I/O (input/output) functions such as inp() and outp() from within an application for Windows NT running in user mode causes a privileged instruction exception to occur. The sample code provided in the OUTP.C online help sample for the outp() function and related functions can be used to illustrate this behavior.

The documentation regarding the compatibility of the port I/O functions is incomplete. Win32-based applications that call inp(), outp(), and so forth can be successfully compiled and linked. However, these applications will generate the privileged instruction exception because the port I/O functions cannot be called from code running in user mode.

Do not call the following functions from within a Win32-based application executing in user mode:

_inp()
_inpw()
_inpd()
_outp()
_outpw()
_outpd()
NOTE: This documentation error has been corrected for the Visual C++ 4.0 Books Online. The descriptions of the various port I/O functions do not list "Win NT" in the Compatibility section.

MORE INFORMATION
According to the documentation provided with Visual C++ 32-bit Edition, inp(), outp(), and the other port I/O related functions are Win32 and Win32s compatible. However, executing code that uses these functions causes a privileged instruction exception on Win32 on Windows NT. The code that uses inp(), outp(), and so forth will execute correctly on Win32s.

The inp(), outp(), and other I/O port related functions map to privileged processor instructions. For example, on Intel processors, the inp() and outp() functions end up calling the IN and OUT instructions. The privileged instruction exception occurs when these instructions are executed because typical Windows NT applications execute in a nonprivileged (user) mode. Only code executing in kernel mode has the necessary rights to execute privileged instructions. Kernel mode code is typically found in device drivers.

For more information on user mode and kernel mode in Windows NT, refer to the Microsoft Press book "Inside Windows NT" by Helen Custer. For an example of a kernel mode Windows NT device driver that allows user mode applications to access hardware ports, refer to the GENPORT sample provided with the Microsoft Windows NT Device Driver Kit (DDK).

DAO : the memory size increase

Wizard_0125-Dec-01 5:44

25-Dec-01 5:44

code :

void CreateConnetion(){
try{m_db.Open("xxxxx.MDB",FALSE,TRUE); }
catch(CDAOException *e){ .... }
}

void Open(CString Sql){
CloseQuery();
m_pRecordset = new CDaoRecordset(&m_db);
try{m_pRecordset->Open(dbOpenDynaset,Sql,dbReadOnly);}
catch (CDaoException *e) {
...
}
...
}
void CloseConnection(){
CloseQuery();
if (m_db.IsOpen()){
m_db.Close();
}
}
void CloseQuery(){
if (m_pRecordset->IsOpen()){
m_pRecordset->Close();
}
delete m_pRecordset;

}

.
Each time when I call CreateConnection and Open("SELECT * from [table]") the memory size increase. After time when i call CloseConnection the memory size doesnt decrease and app needs 5 MB (before creating connection had 4 MB). Confused | :confused:

{{i use this code :
CreateConnection();
Open();
CloseConnection();
}}

Is is alright ?
Confused | :confused:
