Greetings,
I am very new to C++ and after many searches I am unable to figure out how to set the values of my array containing a character string.
class DataStruct
{
public:
char *mName;
char mInitial;
int mId;
int mAge;
int mDay;
DataStruct(char *Def_mName = "Paddy", char Def_mInitial = 'A' , int Def_mId = 1, int Def_mAge = 1, int Def_mDay = 1)
{
cout << endl << "Constructor Called ";
mName = new char [ strlen(Def_mName) + 1 ];
strcpy_s (mName, strlen(Def_mName) + 1, Def_mName);
mInitial = Def_mInitial;
mId = Def_mId;
mAge = Def_mAge;
mDay = Def_mDay;
}
When trying to use:
DataStruct data1[2] = { ("Andy",'A',1,20,30), ("Andy",'A',1,20,30 )};
I get the error:
error C2440: 'initializing' : cannot convert from 'int' to 'DataStruct'
Clearly I am not understanding somthing correctly either about strings or pointers, I am trying not to use specific string lengths if possible in this scenario.
Please can someone tell me what command I should be using to create this array, also if possible I would like to dynamicaly create the array data1 using new if anyone would be kind enough to show that example too.
Kind regards,
BS

Two problems:
1) You're using the wrong brackets in your initializer list:
DataStruct data1[2] = { ("Andy",'A',1,20,30), ("Andy",'A',1,20,30 )};
should be
DataStruct data1[2] = { {"Andy",'A',1,20,30}, {"Andy",'A',1,20,30 }};
2) You can't use an initializer list like this unless you remove the constructor from the struct.
See Compiler Error C2552[^] for details.

Many thanks Mark,
It did indeed work as you suggested, I am presuming that the compiler error was raised because the character array was not a fixed length.
I am plagued with a habbit of throwing myself off the deep end, anyway, thanks again for your very fast response.

Actually it was the constructor...
From the docs:
"The following represent the reasons C2552 may fire when an aggregate initialization is attempted
on a type:
The type has one or more user-defined constructors."
where agregate is defined as:
"An aggregate type is an array, class, or structure type which:
Has no constructors
Has no nonpublic members
Has no base classes
Has no virtual functions "

If you never threw yourself off the deep end you would learn a lot less - keep diving.

You can keep the ctor if you initialize the array like this:
DataStruct data1[2] = { DataStruct("Andy",'A',1,20,30), DataStruct("Andy",'A',1,20,30) };

How to handle click event on icon which is placed on status bar?
Answers are appreciated.
|
|
|
|
|
You can respond to the message you indicated in NOTIFYICONDATA.uCallbackMessage when you
added the icon with Shell_NotifyIcon().
NOTIFYICONDATA.hWnd needs to be valid and NOTIFYICONDATA.uFlags needs to have the NIF_MESSAGE
flag as well.
Or were you referring to a status bar in an application window...

 Maybe in assumptions and/or jumping to conclusions, or not reading posts thoroughly

No prob.

North Orange County - Fullerton. You're in LA? For some reason I was under the impression you were in Europe...I figured you just never slept since you were around here the same hours as me.

Derive a new class from CStatusBar. Add WM_LBUTTONUP handler, and in this function loop through all panes of status bar -
- use GetStatusBarCtrl() to get ptr to control
- use CStatusBarCtrl::GetRect() to get rect of pane
- use rect.PtInRect() to see if click was in pane's rect
(I assume you mean app's status bar.)

Thank you Hans.
Yes its an application's status bar.
I'll try ur solution. Is there any other better solution?

Hi everybody.
I encountered a problem while using the Video Mixing Renderer 9 to display video file and camera.
In fact, each time I change the video file to play, I destroy the graph by that I mean I remove all the filters in the graph. Then, I build a new graph again including the Video Mixing Renderer in it.
The problem is that it works fine for a moment but while using about 10 times this method, my video is not shown and there is an Active Movie Window which appear and displays nothing in it.
I haven't find out what was the problem.
Could somebody help please?
Thanks in advance

Hi all,
How can I catch/handle a double-click (left mouse button) on the header control of a CListCtrl.
TIA

Handle the HDN_ITEMDBLCLICK message that will be sent from the header.
Peace!

Hai evryone,
I have a problem with internet file download i.e.,synchronous download.this is how it is..
1. I have an internet file which is to be downloaded using multiple threads
(single file/same file).I'm using UserInterfaceThreads where in i pass
parameters such as starting position of a file, temp name of the file
etc.. problem is i'm unable to download to diff files(threads)
synchronously.i.e., files are downloaded one thread after the other.
code is given below...
parameter fPos: the start position of the file to be downloaded which
is initilized when thread is created.
m_hHttpFile = HttpOpenRequest(m_hHttpConnection, "GET", ServerFile,
NULL, NULL, ppszAcceptTypes, INTERNET_FLAG_RELOAD
|INTERNET_FLAG_KEEP_CONNECTION, NULL);
::InternetSetFilePointer (m_hHttpFile,fPos,0, FILE_BEGIN, 0);
do
{
::InternetReadFile(m_hHttpFile, szReadBuf, TRANSFER_SIZE,
&dwBytesRead))
...... write in to my temp files..
}
while(sum

Maximum connection per server for Wininet library is 2 by default for HTTP 1.1, and 4 for HTTP 1.0. Please refer to the article:
http://support.microsoft.com/kb/183110
I also had encountered the same problem before. Because I did it for my own usage, I just increased the values in the registry. However, according to RFC2616, it is not recommended to maintain more than 2 concurrent connections from the single client to the same server.
BTW, for that small program, I make sure that each worker thread keeps its own internet session and internet connection. Maybe you could try it.
One more thing, if I am not wrong, INTERNET_FLAG_KEEP_CONNECTION flag enforces the client to reuse the existing connection. To verify that multiple connections are opened, in the command prompt, type "netstat -a".
Good luck!
