Hello everybody.
I'm a MFC developer and I have a problem; i could not read a xml file in mfc (vs 6.0, c++). I don't know the differences reading a text file with reading a xml file, in mfc. Also; i don't know the xml open-read-write methods of the MFC (if there is??? ). How can I open and read xml files? Please help me.
Thanks in advance.

Hi Friends,
In socket programming I want to connect double byte charcters.
Earlier we used recv() function for single byte charcter.
If we use double byte chracter in below recv function, its coming as a question mark symbol.
If anybody knows how can I handle double byte charcter in Scoket programing(recv function),Please let me know.
My codesnippet:
while( bytesRecv == SOCKET_ERROR ) {
bytesRecv = recv( ConnectSocket, recvbuf, 64, 0 );
if ( bytesRecv == 0 || bytesRecv == WSAECONNRESET || CheckTimeOut()) {
return CloseListen();
}
}
Note:Here recvbuf works for singel byte not for doublebyte charcters.
Thanks in advance.

You need to do some studying on character encoding, thinks like Unicode etc. Here is just one example[^]

In addition to led mike's reply...
Sockets work in bytes, that's it. If you need to work with any other types
then you need to do the multiplication yourself to calculate the number of bytes
for a given type.
recv() is confusing with its char* type - it actually has nothing to do with
"characters" - it's just what the BYTE type was at the time it was designed.
It's ancient, and most wish it would go away.

You do not read the event file(s) directly. There is an API for doing that. Hans' article goes over all of this very well.

Buddy, it would be better you ask this question in WIX support forum, here i believe very few people are aware of this installer, generally people prefer installar shipped with VisualStudio or MacroVision Installshield on paid side and Innosetup on free side.

Hi,
I have created a service not specifying the username/credentails i.e. local-account. I am trying to change the user to "domain\username" dynamically using ChangeServiceConfig API. This API always returns me error code 87 i.e. “The parameter is incorrect”.
I have explained the problem below. Does anyone why this behavior?
I have detailed the steps below:
I have an issue. I create a service under the local system account. After that I am trying to change the user to domain\user. E.g.: if my domain name is “MSDN” and username name is “me”, I am trying to change the user credentials to “MSDN\me” using the ChangeServiceConfig API. This API is always throwing me an error 87 i.e. “The parameter is incorrect”.
#define SZSERVICENAME “Trial”
ServiceCreate()
{
schSCManager = OpenSCManager(NULL, // machine (NULL == local)
NULL, // database (NULL == default)
SC_MANAGER_CONNECT | SC_MANAGER_CREATE_SERVICE // access required
);
schService = CreateService(schSCManager, // SCManager database
TEXT(SZSERVICENAME), // name of service
TEXT(SZSERVICENAME), // name to display
SERVICE_ALL_ACCESS, // desired access
SERVICE_INTERACTIVE_PROCESS|SERVICE_WIN32_OWN_PROCESS, // service type
SERVICE_AUTO_START, //SERVICE_DEMAND_START start type
SERVICE_ERROR_NORMAL, // error control type
szPath, // service's binary
NULL, // no load ordering group
NULL, // no tag identifier
TEXT(SZDEPENDENCIES), // dependencies
NULL, // LocalSystem account
NULL); // no password
}
ChangeServiceParms()
{
//Domain = “msdn.try.com”, computer name is “comp”
LPTSTR szServerDNS = “comp.msdn.try.com”;//Fullname of the computer
LPTSTR szAccountDN = “MSDN\me”;// User to which I am trying to logon
schSCManager = OpenSCManager(szServerDNS,
NULL,
SC_MANAGER_CONNECT );
BOOL success = ChangeServiceConfig(service,
SERVICE_NO_CHANGE,
SERVICE_NO_CHANGE,
SERVICE_NO_CHANGE,
NULL,
NULL,
NULL,
NULL,
szAccountDN,
NULL,
NULL);
if(!success)
{
DWORD err = GetLastError();
}
}

I basically have three group boxes.
The first group box has 2 radio buttons with labels reading “Choice A” and “Choice B”
The second group box is entitled “Choice A” and has several radio buttons within it.
The third group box is entitled “Choice B” and has several radio buttons within it.
I basically start off the program with group boxes “Choice A” and “Choice B” and their contents invisible.
Now, what I can’t figure out is:
When I click “Choice A” in the first group box, I want the “Choice A” group box and its contents showing up (with “Choice B” and its contents still invisible) and vice-versa.
I don’t necessarily need code, just a push in the right direction.
I’ve looked at several tutorials involving adding member variables and such to the radio buttons, but the tutorials were for an older version of Visual C++ and the ClassWizard has changed enough to cause conversion issues when I (attempted to) follow along.
However, I’m hoping the answer will be a simple “on push, choiceA.radiobutton1.visible=true;” type of thing.
Thanks in advance.

This seems to be C#, in VC++ I would make it like...
supposing you have member variables for every element...
If (m_rbChoiceA.GetSelect ())
{
m_rbChoiceA_1.ShowWindow (TRUE);
;
m_rbChoiceB_1.ShowWindow (FALSE);
}
and the opossite when B is selected.
I hope it helps you a bit, sorry but I didn't use C# yet.
BTW, I think is better to enable/disable than show/hide, I had a endless loop in OnPaint bcause of ShowWindow because it sends a "redraw" message internally.
Greetings.

Add the code below in the OnInitDialog function call
where IDC_STATIC is ID of Group box and IDC_RADIO3 the ID of the Radio Button. This may be different for your application hence needs to be changed accordingly.
<br />
GetDlgItem(IDC_STATIC)->ShowWindow(SW_HIDE);<br />
GetDlgItem(IDC_STATIC1)->ShowWindow(SW_HIDE);<br />
<br />
GetDlgItem(IDC_RADIO3)->ShowWindow(SW_HIDE);<br />
GetDlgItem(IDC_RADIO4)->ShowWindow(SW_HIDE);<br />
<br />
GetDlgItem(IDC_RADIO5)->ShowWindow(SW_HIDE);<br />
GetDlgItem(IDC_RADIO6)->ShowWindow(SW_HIDE);<br />
This will make sure that the 1st time you start your application, the 2 group boxes are visible.
Now handle the Single Click event of the 2 Radio buttons.
Add the following code in the "Choice A" radio button event handling function.
<br />
GetDlgItem(IDC_STATIC)->ShowWindow(SW_SHOW);<br />
GetDlgItem(IDC_RADIO3)->ShowWindow(SW_SHOW);<br />
GetDlgItem(IDC_RADIO4)->ShowWindow(SW_SHOW);<br />
If you want dont want Group A radio buttons/box to be visible when you click on the 2nd radio button, please hide the same.
