Hello!
I started using VC++ .NET just recently. I made small app with some single line edit controls on it (with .NET resource builder). I don't process any events from edit controlls yet, but I have very strange situation. I start the app and click on some edit control and write some text. When I press ENTER, the app closes. It doesnt matter if edit control was empty or with some text. I don't process any messages from edit control so I would expect nothing would happen.
I don't know why that happens. Am I missing something? I don't remember having such a problem on VC++ v6.0.
Best regards,
Rostfrei

Actually On Pressing Enter it call Default Button , In you case that's OK Button Which close down you application.
now you have two solution of above Problem
Either HANDLE OnOk Message or Select Want Return property of Your Edit Control.

I set the Want Return property of edit control to false, but still doesn't help.

Set It to TRUE or make a Dummy Button on you Dialog Sheet and Make it Default Button by Selecting Default Button

Makeing dummy (not visible) button with Default Button by property set helped. Thank you. But it still bothers me I don't know where it is processed

Mr. Giorgi Moniava had given you technique to handle that in Future!
Hope So, you don't have problem dealing with DEFAULT BUTTON in Future!

Next time when you write program , doubleclick on the Ok button and simply delete the line :
void CyouDlg::OnBnClickedOk()
{
// TODO: Add your control notification handler code here
// OnOK();
}
So you will not experience such problems anymore

Hi,
In C++ .NET ios::nocreate is not supported.
How can we replace this code to check file existance:
ifstream cvr_file(file_name, ios::nocreate);
if (!cvr_file.good())
return;
Thanks in advance,

Hello!
I searched all over the net for the following solution. I have some MFC dialog based application. I still want to use printf, cout, etc., but there is no console window, just dialog. Is there some way to use stdout the same way like in command prompt programs?
I found one way of doing this:
AllocConsole();
WriteFile(GetStdHandle(STD_OUTPUT_HANDLE),(void *)out,(DWORD)strlen(out),&written,0);
but the problem here is that you have to use WriteFile function and cout or printf does not work.
Best regards,
Rostfrei

You can show a console, by adding the following line in Post-Build in Project Properties (VC2003) or Project Settings Post-Build Step (VC6).
editbin /SUBSYSTEM:CONSOLE "$(OUTDIR)"\<program name="">
Where program name is the name of your final build exe.
If i am building Notepad.exe, then it would be
editbin /SUBSYSTEM:CONSOLE "$(OUTDIR)"\notepad.exe
You can also call it from cmd.exe manually
editbin /SUBSYSTEM:CONSOLE c:\programfiles\etc\etc\notepad.exe

Friends,
We can detect that IE is currently set to 'Work Offline' using InternetGetConnectedState().
If detected, i want to programatically change the 'Work Offline' state to the normal 'Online' state. How can i do so ?

What is your Mode of your Internet connection! i.e. Is it through CABLE or DIALUP.
If DialUp you can use these api's too [InternetAutodial] and [Internetdial]

I switched my browser to offline mode and opened Outlook Express Mail client. It immediately popped up a dialog that IE is in offline mode and whether I want to switch it to online mode. If I press "yes" it automatically changes it to online mode. As such there must be some way that external applications can switch the browser to online mode, afterall Outlook Express does this.

I would look into InternetCheckConnection(...), it has a flag that forces connection; and InternetAttemptConnect(...).
Peace!

Hi all,
I do a job relating to SOAP initialize. Sometime, SOAP initialize fail
because, SOAP uses Wininet library as default and uses the proxy setting in IE, and this setting was not correct . Some one recommended me to use Winhttp instead of Wininet.
Dim Client
Set Client = Server.CreateObject ("MSSoap.SoapClient30")
Client.ClientProperty("ServerHTTPRequest") = True
Call Client.mssoapinit("http://..../SampleWSDL.wsdl",
"http://...../SampleWSML.wsml")
If Client.ClientProperty("ServerHTTPRequest") = True, SOAP will use Winhttp instead of Wininet.
But I don't know what differences between Winhttp and Wininet are?
Any of u have experiences about this? Can u help me to answer following questions:
1. What are differences between WinInet and WinHTTP? (using in SOAP)
2. problems if we use WinHTTP.
Client.ClientProperty("ServerHTTPRequest") = True
Thanks very much for any your ideas,
Tin Le

How to get the PhysicalDrive number which the logical drive located?
Like how to get the PhysicalDrive number of "C:" logical drive ?
Thanks a lot!

HI Dragon,
have a look at Win32_DiskDrive WMI Class!

LPTSTR lpVolumeNameBuffer[100];
LPDWORD lpVolumeSerialNumber;
LPDWORD lpMaximumComponentLength;
LPDWORD lpFileSystemFlags;
LPTSTR lpFileSystemNameBuffer[100];
GetVolumeInformation("C:\\",lpVolumeNameBuffer,100,&lpVolumeSerialNumber,
lpMaximumComponentLength,lpFileSystemFlags,lpFileSystemNameBuffer,100 );
use the above function it returns the Volume Serial Number of the physical C drive .
Cheers

Hmmm. How about:
<br />
TCHAR caVolumeNameBuffer[ 100 ];<br />
DWORD dwVolumeSerialNumber = 0;<br />
DWORD dwMaximumComponentLength = 0;<br />
DWORD dwFileSystemFlags = 0;<br />
TCHAR caFileSystemNameBuffer[ 100 ];<br />
<br />
GetVolumeInformation( _T( "C:\\" ), caVolumeNameBuffer, 100, &dwVolumeSerialNumber, &dwMaximumComponentLength, &dwFileSystemFlags, caFileSystemNameBuffer, 100 );<br />
Your example was not passing in valid pointers, only uninitialized ones. Might want to ensure proper termination of the TCHAR buffers as well.
However, I think the OP was asking about the physical device name for the drive, not its serial number; I think they were looking for information such as if a drive is \\.\PhysicalDrive0 or \\.\PhysicalDrive1, etc. You need that information to open the device itself (the hard drive itself) to do things like send IOCTLs. I do not think that the function you specified will return that information.
Peace!

If you need that to do something like send IOCTLs (DeviceIoControl), you can also open the device by using the following syntax:
\\.\C: - Open physical device for drive "C"
\\.\D: - Open physical device for drive "D"
\\.\A: - Open physical device for drive "A"
I do not know all of the cases where that format and the \\.\PhysicalDrivex format are interchangable, but I know you can use it when getting a HANDLE to use with DeviceIoControl.
Also, not that you are likely to hit it, but there is a bug in older versions of the Win32_DiskDrive WMI class that limits the number of drives returned. The above method should also work on Windows NT 4.0 versions prior to SP4, but the WMI method will not.
Peace!
