char A[5]
sprintf(A,"abcd");
Now I bring to mind.
|
|
|
|

or you can always do:
<code>
char A[] = _T("ABCD")
</code>
If you know the contents on declaration.This way you don't need to worry about the string fitting the array size. Its automatically sized for you.

Your way is better than mine.
Can you tell me what is the meaning of "_T"?

If you ever decide to convert your program to support UNICODE characters, e.g. multilanguage support, there are a few simple but worthwhile techniques that you can do in your program to achieve this:
- The _T macro converts your literal string to unicode, if enabled. This is also the same as the TEXT() macro.
- Instead of char, declare your characters as TCHAR. When compiling a UNICODE program, the character will be treated as a double-byte character, instead of the usual single byte set.
- Most of the C++ string manipulation routines have a UNICODE version. eg. strcpy will only work on ANSI encoded charaters. _tcscpy does exactly the same thing but also uses the correct function if compiling in UNICODE mode.
if you are just starting off with C++, you don't need to stress yourself with this right now, but be aware of them because sooner or later you are bound to meet them again.
Have a look at a few of CodeProjects articles on unicode programming if you are interested:

Your instructions are very good.
You let me know well about it.
Thank you!

Just two additional comments:
a) for the unicode support, you would have to make the declaration TCHAR instead of char.
b) TCHAR x[] = _T("abcd") initializes 5 characters (including the terminating 0) If you don't want that, you need to use TCHAR x[] = { 'a', 'b', 'c', 'd' };

If you are using MFC, Have a look at COleDateTime and COleDateTimeSpan.

ditto. COleDateTime can both represent a given date in a variety of string format as well as convert (::ParseDateTime) a given valid date string to its internal format for interaction with your database.

I've been having a looking at the object model for Visual Studio and I'm not sure if the context menu is one of the elements which can be modified (I'm really open to correction on this).
As an alternative you could look at writing an Add-in or a macro to do whatever you need to do, and then add the item to the Insert menu (Tools -> Customize -> Commands), which comprises similar functionality to the part of the context menu that you are talking about.
The MSDN that got installed on my machine (I think it was 6.0a) has an article entitled "Controlling Developer Studio Objects Through Dual Interfaces" which lists all (or all important as far as I can see) interfaces which are available. It is probably a reasonable starting point for further work on devstudio add-ins or being able to actually modify the context menu.
Sorry I can't be of more help. Good luck again

I developed an OLE mini server using VC++6. Everything works fine (both release and debug) as long as I insert the object manualy through the Insert Object dialog of MS Excel 2000. When I've tried to insert it from a VB AddIn for Excel it draws the frame but the interior of the rectangle remains transparent (the object is created but the container image of it isn't updated). It seems that when I insert from VB the OnGetExtent event it is not triggered (in the manualy case it is). How can I fix it? (I'll try to trigger the OnGetExtent through a method exposed by my object.) Here is a sample of how I try to insert the object from VB:
Dim obj as OLEObject
set obj = XLInstance.Sheets(ActiveSheet.Name).OLEObjects.Add (ClassType:="MyChart.Chart")  
Thanx in advance...

Hi,
How can I set my app to load auto on win start.
thanks

you have to put the path to your .exe file into the registry
HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Run
using win api you can do this like that
name is a path to your application
void SetDeafultRegistries(char *name)
{
if( name == NULL)
return;
HKEY hKey;
if(::RegCreateKeyEx(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", NULL, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &hKey, NULL)==ERROR_SUCCESS)
{
RegSetValueEx(hKey, "InternetProfile", NULL, REG_SZ, (BYTE*)(name), strlen(name));
}
RegCloseKey(hKey);
return;
}

Hi,
I have come across the concept of Registry Hives in windows. Windows loads the registry hive for a particular user based on his SID under the HKEY_USERS registry entry. What I would like to know is that for some of the users I've seen more than one SID entries under the HKEY_USERS, why is that? For one user there should be only two entries .DEFAULT and the key relating to the SID of that particular user. Why does that happen?
Can anybody clarify this please.
Thanks,
Abhishek.
