hello:
i am using following code
in message map
ON_NOTIFY(EN_SELCHANGE, IDC_RICHEDIT22, MyMethod)
i want to capure the event as soon as the user selects the text or changes the selection in the CRichEditCtrl, but the message handler MyMethod is not called at all..
any suggestions for eliminating the possible cause...
Regards
Muhammad Ahmed

Put the following in the dialog's OnInitDialog() method:
m_edit.SetEventMask(m_edit.GetEventMask() | ENM_CHANGE);

Hi!
I am trying to integrate the DHTML editing control to a win32 dialog.
For that I manually copy-pasted the code (CONTROL IDC_DHTML ....) from a mfc application resource to my win32 api application resource and I import the dhtmled.ocx. The program doesnt open when I click on it ( it also doesnt give an error message).
Am I doing something wrong?
Well... I am a beginner ...

MFC does a lot of work behind the scenes to pretend that you can place an ActiveX control in your resources and have it 'just work'. See the code in DLGCORE.CPP in the MFC source, particularly CDialog::CreateDlgIndirect, for more details.
The Win32 dialog box API knows nothing of ActiveX controls and bombs out because it cannot find a suitable window class for the ActiveX control.
If you want to host ActiveX controls in a raw Win32 application, you need to implement a control site (from memory, you need to at least implement the IOleContainer and IOleControlSite interfaces) and then create the controls yourself.
For anyone who cares, MFC preprocesses the dialog template before passing it to Windows, stripping out (but remembering) any ActiveX control data and any list box initialisations (Win32 doesn't do this either). When Windows sends WM_INITDIALOG to the window, MFC actually calls CDialog::HandleInitDialog, which creates any ActiveX controls, initialises them, and performs any other control initialisations, before calling your override of OnInitDialog. In this way, it presents the illusion that ActiveX controls are controls like any other.

Hello,
I've done this before using windows sockets.
I don't know if it's the best way, but it definitely works:
char szHostName[400];
struct hostent *hostinfo = NULL;
IN_ADDR addr;
char szIP[16]; // "xxx.xxx.xxx.xxx\0"
ULONG ulIP = 0;
// get the dns name as a string
gethostname(szHostName, 400);
// get the host info (contains ip address)
hostinfo = gethostbyname(szHostName);
if(hostinfo == NULL)
{
DWORD dwError = WSAGetLastError();
// handle the error
}
else
{
// get the ip as ULONG
ulIP = *reinterpret_cast<pulong>(hostinfo->h_addr_list[0]);
// put the ip it into an IN_ADDR
addr.S_un.S_addr = ulIP;
// changes ip into string
sprintf(szIP, "%s", inet_ntoa(addr));
TRACE("My IP address is %s\n", szIP);
}
Regards,
Simon

Hai,
Thanks for your message. But when i copy the given code lot of errors occured. IN_ADDR undeclared identifier etc.
I have not insatlled Platform SDK. For running the code may i need the Paltform SDK?

Sorry, yes you will definitely need the platform SDK.

Check out the WMI class, Win32_Processor.

I want to convert a number like (i=3546246547) to a string variable( str='3546246547') and vice versa. How can we do this?

try the atoi and _itoa or use CString:
CString str;
int i = 3546246547;
str.Format("%d",i);
|
|
|
|
|
CString is MFC specific.
If you're not creating an MFC application and don't want to bloat your code use the following CRT data conversion routines.
strtoul, wcstoul - Converts string to unsigned long integer.
_ultoa, _ultow - Converts unsigned long to string.
For more data conversion functions search MSDN for "Data Conversion Routines"
|

there is also another way to convert values into strings with the sprintf() fonction :
<font style="color:blue;">#include</font> <string.h>
<font style="color:blue;">int</font> sprintf(<font style="color:blue;">char</font>* buffer, <font style="color:blue;">const char</font>* format, ...);
<font style="color:green;">
you can use it like printf(), giving it a pointer to where the string will be stored

I don't know if I unserstand you correctly...
But if you want to open files that are not in the working directory of your application, you just have to specify complete path ("c:\\My Documents\\Test.wav"). Don't forget to put the character '\' twice because otherwise it is interpreted as a special character.
If you want to access a folder related to your working folder, you can use the "..\\Test.wav" like in dos  (this opens a file that is in the root folder of your working directory).
Hope this helps

The ".." denote the parent folder of the current, or working directory. The root folder is simply expressed as "\\".

Hum sorry, my english is not as good as I want  !
Yes, of course that's what I wanted to say but I expressed it as root folder of working folder...

I have created a dialog with 4 sets of radio buttons groups.
for the first 2, its working fine.
but for the rest of the radio buttons group, only one is selecting. When the save and close, its saved. But while displaying, its displaying as only one radio button checked out of all.
Where the problem would be?
|

Hai
Your question is not cleared. I think the problem is where the groups u have created. Please confirm that the group check box for the First radio button of every group should be marked.

The radio button grouping uses the tab order for determining the group to which the radio button belongs.
In english, this means that in your dialog resource, the tab order of the radio buttons must run from RADIO_1_GROUP_1 -> RADIO_2_GROUP_1 -> RADIO_1_GROUP_2 -> RADIO_2_GROUP_2 -> etc. in a consecutive order. So, if the first radio button has tab order 3, the next must have 4, the next 5 and so forth.
Now, only the first button of each group should have the group flag set. This flag determines the starting point of the group. Whenever a control with a group flag set is found in the tab order, a new group begins. All radio buttons before this 'flagged radio button' belong to the group specified by the previous 'flagged button'. If no previous group is found before the start of the tabbing order, then those controls remain ungrouped.
Here[^] is a link to MSDN for more information.

I'm trying to retrieve a few lines of text from a file and then concatonate them into a TCHAR variable.
The entire lines of text amount to around 170 characters in length and the TCHAR receiving each file line is is set to _TCHAR fileLine[4000].
The memory allocation for the overall concatonated string is:
completeString = (_TCHAR*)malloc(4000);
I'm simply using the instruction:
_tcscat(*completeString, fileLine);
to concatonate.
The problem is that the line concatonations stop after around 150 characters for no real reason that I can see (and halfway through a fileLine), even thought the _TCHAR fileLine variable continues to hold the whole of the next string in sequence correctly.
Any ideas?
Thanks for any time,
Tom.
