Simple: recursion!

There is only one ntimes-variable (that's what staic means), and it is initialised only once when encountered the first time.
As long as it is below 100, recur() is calling itself, incrementing the variable.
When it reaches 100, a text is printed and all the pending recur()-function come to decrement ntimes.

"We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganised. I was to learn later in life that we tend to meet any new situation by reorganising: and a wonderful method it can be for creating the illusion of progress, while producing confusion, inefficiency and demoralisation."

-- Caius Petronius, Roman Consul, 66 A.D.

what don't you understand exactly ? the use of the static keyword, and how it works, of the principle of recursion ?

Command-line code merged with GUI

It is doing the same thing as the following:

int recur(int count)
{
        if (100 <= count)
        {
                return count;
        }
        else
        {
                int c = count++;
                printf("%d\n", recur(count));
                return c;
        }
}

Alright, I have my GUI written in C and the other document is in command-line and written in C++. I'd like to the command-line code into my GUI on a click of a certain menu item(ID_CONVERT_DEAD) and I do not know how to do so.

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)//Window Procedure<br />
{<br />
switch(msg)<br />
{<br />
case WM_CREATE://Creates the File and Convert to.. menus.<br />
{<br />
HMENU hMenu, hSubMenu;<br />
HICON hIcon, hIconSm;<br />
<br />
hMenu = CreateMenu();<br />
<br />
hSubMenu = CreatePopupMenu();<br />
AppendMenu(hSubMenu, MF_STRING, ID_FILE_EXIT, "E&xit");<br />
AppendMenu(hMenu, MF_STRING | MF_POPUP, (UINT)hSubMenu, "&File");<br />
<br />
<br />
hSubMenu = CreatePopupMenu();<br />
AppendMenu(hSubMenu, MF_STRING, ID_CONVERT_MM, "&MessengerMate");<br />
AppendMenu(hSubMenu, MF_STRING, ID_CONVERT_MIDDLE, "&Middle_Man(Coming Soon..)");<br />
AppendMenu(hMenu, MF_STRING | MF_POPUP, (UINT)hSubMenu, "&Convert to..");<br />
<br />
SetMenu(hwnd, hMenu);<br />
<br />
<br />
hIcon= LoadImage(NULL, "RidV.ico", IMAGE_ICON, 32, 32, LR_LOADFROMFILE);<br />
if(hIcon)<br />
SendMessage(hwnd, WM_SETICON, ICON_BIG, (LPARAM)hIcon);<br />
else<br />
MessageBox(hwnd, "Could not load large icon!", "Error", MB_OK | MB_ICONERROR);<br />
<br />
hIconSm= LoadImage(NULL, "RidV16.ico", IMAGE_ICON, 16, 16, LR_LOADFROMFILE);<br />
if(hIconSm)<br />
SendMessage(hwnd, WM_SETICON, ICON_SMALL, (LPARAM)hIconSm);<br />
else<br />
MessageBox(hwnd, "Could not load small icon!", "Error", MB_OK | MB_ICONERROR);<br />
}<br />
break;<br />
case WM_COMMAND:<br />
switch(LOWORD(wParam))<br />
{<br />
break;<br />
<br />
case ID_FILE_EXIT://Commands for Menu items go in the specified menu item.<br />
PostMessage(hwnd, WM_CLOSE, 0, 0);<br />
break;<br />
case ID_CONVERT_MM:<br />
<br />
break;<br />
case ID_CONVERT_MIDDLE:<br />
<br />
break;<br />
}<br />
<br />
break;<br />
case WM_CLOSE://Default reaction when users press the "x" button or Alt-F4<br />
DestroyWindow(hwnd);<br />
break;<br />
case WM_DESTROY://Destroys all windows including child windows(We have none, yet.)<br />
PostQuitMessage(0);<br />
break;<br />
default:<br />
return DefWindowProc(hwnd, msg, wParam, lParam);<br />
}<br />
return 0;<br />
}

All this info is just to give you an idea of what I want to do since I'm not too sure what the technical term for the procedure is. Also, whenever I move the installer out of the directory that the icons are in, it'll produce the errors and i'm wondering how to fix it to where no matter where the installer is, it shows the icons. I've already tried googling and searching through every C/C++ site out there on how about to do this but as I didn't know exactly what I was looking for I wasted hours so I decided to come to this message board for help.

Any help is greatly appreciated.

how's supposed to be called the command-line exe ?

can't you just use ::ShellExecute() ?

Alright, I'll try and make it clearer as I know my post probably didn't make much sense.

I don't want the command-line.exe, I want to incorporate the code that's in the command-line program into my GUI. I have the source files for the command-line program and would like to be able to put the source for the command-line into my GUI and be able to run the source I put from the command-line from a menu item(ID_CONVERT_DEAD). I just need to incorporate it into my GUI and Window app.

Does this clear it up a bit?

if you have the source, then what's the problem ?
can't you copy/paste the code you need in your new project ? Confused | :confused:

Also, if I add all those I still don't know how to execute the certain commands on the menu item.

Hi, all.
I am encoutering some communication problem while using synchronous SOCKET.
I have a client which sends data to server with Gbps network in the speed of about 200kB/s. I invoke select function to judge whether I can send data everytime.If it fails I will re-create a socket to connect the server. But when I count the packets sent in client and received in server, I find they are not the same. why this happens? how to impove it?

From my little experience with winsock, I suggest that you do not re-create a socket everytime select fails (if 'fails' means that you cant write to the socket at the moment), but if 'fails' means that the connection fails, you should recreate a socket on the client AND put the socket on the server in listen mode.

I imagine that ur problem goes in the following scenario:

Client: Connect ,Server:OK
Client: Send ,Server: recv
Client: Send (fails) ,Server recv() no data
Client: Re-connect , Server (Still waiting for data) - not ready to welcome incoming connection

Mohammad

C++ MDI and CreateProcess

Is it possible to have a multi-document project and make one of the documents another executable from createprocess or shellexecute? I guess an example would be starting up the calculator inside a C++ MDI application AND have it be a child document.

Chris a "process" is NOT a "document". Please clarify.

I think I figured it out in a round about way. It looks like I am going to have to create a blank document and use createprocess to create a process and then position the process overtop the blank document to give a feel that it is inside the window. Ofcourse I am going to have to handle the size changes and the position changes but this is the only solution I have right now.

Chris, are you new to MFC? In MFC using the word "document" is associated to the CDocument class. CDocument is NOT a "window" or visual class but is designed to expose "data" elements of the application. It might be viewed as the "model" element of the Model View Controller design pattern.

That sounds like a terrible hack and not advisable. Good luck with that solution.

I know it sounds like a terrible hack and I really cannot argue because it is a terrible hack, but if anyone has any better solutions, I would be greatly appreciative. My main goal is to be able to use C# Forms created in Visual Studio 8.0 in a C++ application in Visual Studio 6.0. I do not want to have to create an ActiveX control to do this.
