hey all!
when using rich edit ctrl, I can't insert any unicode string that is not pute English.
I have create an application that have many windows controls, all of them respond
correctly to the unicode string (wchar_t []) that's includs the regular edit class.
however, I need the formatting, font color and size that is offered fy this control.
I didn't find any help on that in the MSDN...
any ideas anybody?

Did u try finding CHARFORMAT, its a structure that containg all the formating features... pretty useful with richedit ctrl.

HI all;
I am building an application which should have a tab control on a CDialogBar. Visual C++ gladly added the dockable dialog bar for me but i could not figure out where to put the code to create the tab control since the OnInitDialog() function is simply ineffective. Can anybody please help out. I need to know where i should place my code to create the TAb control on the dialogbar.
I badly need this guys;
THanks

Hi, I can't find any way to resize class arrays
created using "new"
is it right to use C memory allocation functions for class arrays and then call constructors/destructors 
|

You definitely wouldn't want to use realloc with an object created with new. You need to leave that old C stuff behind.
If you are using MFC CArray or better still STL vector then they will resize themselves as required.

If you're using MFC, you can use SetSize() to preallocate a CArray's storage. This is useful when optimizing deserialization of a collection. The size of the collection will grow as you add more elements.

Imagine the following scenario:
One of my applications communicates with another (3rd party, non open source) application via a simple TCP socket. The socket is only used to retrieve the status of the other app (or better, the other app sends its status over the socket). The packets are small, usually below 70 bytes, but they are sent pretty often (about 3-5 times per second). After my app receives a packet from the other app, it sends a small, 33 byte answer. After this answer, the other app sends a new status packet and so on. So much for the scenario...
Now there are two odd things going on.
The first oddity is a packet of 1024 bytes. This packet is mysteriously received by the other app, but I have no idea where this might come from (I'm using Port explorer, and it says that it should come from my app, but that's impossible). The packet arrives shortly after I've sent my "answer" to the other app. It contains my answer plus a lot of garbage. But that's not all...
After a while, the other app stops sending out its status to my app. But! It begins to receive even more of these 1024 byte packets - with the correct status at the beginning! Port explorer still says that all comes from my app, but that's totally impossible (I couldn't even guess the correct status).
So, where might these packets come from? What might make the other app stop sending out its status? Is there a way to get these 1024 byte packets?

Hi!
If you can post some of the code snippets, then there might a chance for a solution. At the moment it seems that you are allocating the buffer of size 1024, and fill in the first few bytes ans send it. Rest is garbage. And btw what kind of sockets you are using? Sync or Async etc.

No, your assumptions are wrong. My buffer is not 1024, and I am not sending it (as I stated, I CANNOT send it, I can't guess the contents of these packets). It is not that simple. The socket on my side is async, but that doesn't matter. I can't say what kind of socket the other program is using (I don't think that they use MFC at all).
And code snippets won't help - it's a simple derivated socket which receives stuff and sends a small reply (and this reply does not contain garbage, nor is it 1024 bytes long).
I can only say that these packages cannot come from my app. I neither can guess the contents of them (that would solve my problems, lol), nor do I send anything at that time (I only send sth. when I receive sth., and as I stated, I don't receive anything after a while... and even if I don't send anything at all these 1024 byte packages arrive at the other app).

Heres what I have...
<br />
{<br />
CMenu menu;<br />
<br />
menu.CreatePopupMenu();<br />
<br />
for (int x = 0; x < ndex; x++)<br />
{<br />
Swap = StrArr.GetAt(x);<br />
if (Swap != "Main")<br />
menu.AppendMenu(MF_STRING, x, Swap);<br />
}<br />
<br />
CPoint point;<br />
GetCursorPos(&point);<br />
SetForegroundWindow();<br />
int Sel = TrackPopupMenuEx(menu.GetSafeHmenu(), TPM_RETURNCMD, point.x, point.y, GetSafeHwnd(), NULL); <br />
PostMessage(WM_NULL, 0, 0);<br />
menu.DestroyMenu();<br />
}<br />
I've deleted variable declarations and some code to save space.
With the AppendMenu(), I'm of course adding menu items. What I want to do is add sub menus to each of these menu items.
Instead of clicking on an item and executing a function, I want a sub menu to pop up. Can't figure out how to do it.
Any help?
Thanks!

The menu objects are always grouped as sub or pop-up menus. Now, considering your code post, there is one crucial difference in creating pop-up menus.
Firstly, you need to create a new CMenu object. Then initialize it with CreatePopupMenu like you have done. After that, you need to create a yet another CMenu item, and initialize it with CreatePopupMenu again.
The second menu object behaves like a pop-up menu on the first one. In order to link these two, first add items and their respective command IDs to the second menu by using AppendMenu or InsertMenu. Then use AppendMenu/InsertMenu on the first menu object, and specify MF_POPUP flag in the first parameter. Adding a MF_STRING flag allows you to have an item text as well, specified in the third parameter. Instead of a command ID in the second parameter, you now must supply a handle to the sub-menu object (HMENU). You can get this from the second menu object by querying CMenu::operator HMENU or CMenu::m_hMenu.
After this, you can launch the first menu object as a pop-up menu with a sub pop-up by calling TrackPopupMenuEx. Here is a complete code fragment to give you a better clue:
CMenu* pMenu = new CMenu();
pMenu->CreatePopupMenu();<DIV>
CMenu* pSubMenu = new CMenu();
pSubMenu->CreatePopupMenu();<DIV>
pSubMenu->AppendMenu( MF_STRING, 1, "Option 1" );
pSubMenu->AppendMenu( MF_STRING, 2, "Option 2" );<DIV>
pMenu->AppendMenu( MF_STRING | MF_POPUP, (UINT_PTR) pSubMenu->m_hMenu, "Sub menu" );<DIV>
pMenu->TrackPopupMenuEx(...);<DIV>
pMenu->RemoveMenu( 0, MF_BYPOSITION );
pSubMenu->DestroyMenu(); delete pSubMenu; pSubMenu = NULL;
pMenu->DestroyMenu(); delete pMenu; pMenu = NULL; I am not certain if the RemoveMenu call is necessary, as the menu cleanup code might have a routine that destroys sub-menus as well. Also, the code has no error-checking routines for possible error states like memory reservation failures or checks whether the pointers are valid. You should include these, or your application might cause access violations.

Hello @all,
I have a C-program with a telephone listing. Now I would like to examine with an entry into the telephone listing whether the entry is already present. How can I examine whether the name in other form (large and lower case) exists?
Thank you,

Hi all,
I am writing a system where a client communicates with a server and amongst other things tells the server what the client's IP and subnet mask are. However, when there are more than 1 network cards on a PC, how can I programmaticaly know which interface a packet is going to be sent on (for a particular destination)? I know how to get a list of interfaces and relevant details but don't know which one to use.

The routing service on the PC will determine from the destination address which interface to use. If, for some reason, you need to select an interface in your app, though, the information stored in the routing table for the PC should be sufficient.
Knowing the destination IP address and subnet mask, you should be able to compare it to the routing table in the machine to find which interface the address fits. If you AND the IP address of the host you want to reach with the subnet mask, the resulting network address should fit into one of the route specifications in the routing table.
The illustrations here - The IP Routing Table - MSDN[^] - provide examples and an excellent explanation of how they're used.

Hi, I'm trying to make a tool using MFC for a game I'm making. And I need a edit control to type in coordinates for objects, and in the end I have to get the coordinate value to be a float. I want the edit control to be fairly user friendly what should I do? Some tutorials seem to make their own classes derived from CEdit, or should I just make a member variable of CEdit type? I've tried making a member variable of type float but that doesn't really seem to let me format the string of the edit control to only accept numeric values etc. If I make a CEdit variable or make my own class derived from CEdit is there some way I can convert the string in the edit control to a float?? Any advice is apreciated
