I have the following code to set one of the menu items as a default one (it should go bold), however the menu item is not displayed bold for some reason:

MENUITEMINFO menuItemInfo;<br />
menuItemInfo.cbSize = sizeof(MENUITEMINFO);<br />
menuItemInfo.fMask = MIIM_STATE;<br />
VERIFY(pSubMenu->GetMenuItemInfo(IDC_SHOWWINDOW,&menuItemInfo));<br />
menuItemInfo.fMask = MIIM_STATE;<br />
menuItemInfo.fType = MFS_ENABLED|MFS_DEFAULT;<br />
VERIFY(pSubMenu->SetMenuItemInfo(IDC_SHOWWINDOW,&menuItemInfo));

Both GetMenuItemInfo() and SetMenuItemInfo() are successful as they return 1, but I cannot figure out why it doesn't display the menu item as bold.

Any help would be greatly appreciated

Thanks

Try to change menuItemInfo.fType = MFS_ENABLED|MFS_DEFAULT; // Type has MFT_
with fState = MFS_ENABLED|MFS_DEFAULT;

I have tried that but for some reason it does not seem to work, that is why I asked the question in the 1st place.

Thanks

I suggest you that you can use another function like this in API: SetMenuDefaultItem(hMenu,IDM_,FALSE);

C#/C++ Interop - Nested Classes

My question deals with writing a managed wrapper interface for a native C++ class such that it can be used by an application that I've written in C#.

The native C++ code has a class, cDSP, which in turn contains four other nested classes:

class cDSP
{
class c1 {}; // and so on to

class c4 {};
};

The C# code deals with only cDSP objects, which access, "behind the scene" so to speak, objects and methods of classes c1 to c4.

My questions is this:

In my managed wrapper class, is it necessary for me to declare pointers to each of these classes or is it sufficient to declare just one pointer to cDSP?

Thanks,

N00B to VC++ Needing Help...Its probably quite simple

First off im a VB man not VC so this is all very new to me,
Ok got a resource file that fails to compile:

Compiling resources...
C:\Documents and Settings\Gaz\Desktop\sig2dat3.11.a-src\sig2dat.rc (13): error RC2104 : undefined keyword or key name: WS_DLGFRAME
Error executing rc.exe.
Creating browse info file...
BSCMAKE: error BK1506 : cannot open file '.\Debug\giFThash.sbr': No such file or directory
Error executing bscmake.exe.

sig2dat.exe - 2 error(s), 0 warning(s)

Now i presume the first part is a c**k up somewhere in the code, but not a clue whats up with the second one,

I presume this is ok:

IDD_ABOUT DIALOGEX DISCARDABLE 0, 0, 350, 350
STYLE WS_DLGFRAME | WS_POPUP | WS_CAPTION | DS_CENTERMOUSE
FONT 8, "MS Sans Serif"

So what am i missing?

Thanks
Sorry about the n00bishness

hi again,
....yeh ok im sure you are probably gettin a bit bored by my n00bishness by now, but got yet another problem......

Ok, now when i try to compile i only get 1 error and 0 warnings,
now from the looks of the error it looks like i have missed yet another include tag off,

C:\Documents and Settings\Gaz\Desktop\sig2dat3.11.a-src\sig2dat.rc (25): error RC2104 : undefined keyword or key name: IDC_STATIC

Currently i only have the following include tags:

<br />
#include <Winuser.h><br />
#include "sig2dat.h" <br />

Thanks

How to get thread handle from thread ID?

If i know the thread id, how could i get the thread handle?
In the Win2000 i can use the OpenThread API, but it's not supported in the Win98.
What could i do under the Win98?
thx.

What are you doing that is differentiating between the two? If the thread is the current one, use GetCurrentThread(). Otherwise, use OpenThread().

It is THE question!
There is no way I know about. You could check how windows ME is doing it.
But I propose that you redesign your software. Where did you get the ThreadId from?

The info you're looking for is all in MSDN: printf Type Field Characters[^].

The use of the rest of the format specifiers can be found by searching through MSDN for printf or sprintf.

Winsock problem.

Hi,
I dont know whether this is the right place for this question, Please excuse if it is not so,.
I have just started programming in winsock.
How is my server intimated that one of the clients has sent it some data?
should I have a loop with the recv(....) function so that it checks continuously for incoming data?
Or are there anyother options?
(Windows is my OS)

Thanks,
Deepak Samuel.

Use accept(). I had a little server application that used the following functions:

WSAStartup()
socket()
bind()
listen()
accept() in loop
closesocket()
WSACleanup()

If you want to wade through some stuff, this link http://www.vijaymukhi.com/vmis/vmchap4.htm should show you an easier way using winsock 2 (that won't freeze your application).

what kind of sockets are you using? TCP or UDP?

There are 4 (as far as I know) ways to get informed about incoming data.
these ways are:
- blocking sockets (call recv() and what till it returns control to your app)
- use select() to check whether there is activity on the socket
- use WSAEventSelect() to assign an EVENT to a socket and then wait for the event
- use WSAAsyncSelect() to make the socket send window messages when there is activity

If you want to create a server which has a main window, then the forth way could be interesting.
If your server doesn't have a window:
- For servers (TCP) with only few clients or UDP servers you should use way one.
- For servers (TCP) with many clients I'd prefer way two (It's also linux compatible Smile | :)

).

I hope I could help....

Hello,

I want to build a NT service. I couldn't find any good articles on the subject until I came across this[^] article.

I find the class (CNTService) which the author refers to highly interesting. The only thing is that I can't download the source code. Dead | X|

.
I don't know if you have to be a MSDN member before you can download the code.

My question is if anybody knows a similar class? If not, I guess that I've to build CNTService myself...

Thanks in advance.
