Using Microsoft Visual C++ 2005EE Compile Error

Hi,

I used to code in C++ but stopped for about a year, anyway I am back but have ran into a problem on my first project:

Any solution I now create doesn't work, when I try and build it it builds fine, but when I try and run it, I get the error that:

"Unable to start program "C:\\...projects\test\debug\test.exe". The system could not find the file specified"

I realise this means that it hasn't created the debug information, but it hasn't created the release information either.

Also I can Build Solution, and it says it is fine, but the Compile option is greyed-out and I don't know what to do.

Is there an option in MVC++EE when you can turn off compiling it until you do something?

Any suggestions?

Thanks,

Any reply is appreciated.

No, it means it can't create the program - your compile is failing due to some other error.

No, there shouldn't be. If it doesn't show the option, it probably doesn't think the option is valid, for some reason.

Ok thanks but I even just tried compiling this in a new solution and it didn't work:

#include <iostream>

using namespace std;

int main()
{
cout<<"This should work...";

return 0;
}

Any ideas?

I have a application in which I have to read a text file with more than 1 hundred thousand lines. I am having trouble with reading file and replacing the text in file. I want to read file's content and display it in Rich text edit quickly, and when I replace some text by other texts, the process must do quickly. I have tried using Notepad to read and replace some text, but it takes about 10 to 15 minutes to finish the works

The fastest text editor I've ever used is called Brief. You can download a trial of V4 here.

The last version I used was 3 and I did search and replace in a 300MB text file on a 90Mhz Pentium OMG | :OMG:

*if* your printer is connected to LPT1 you might be able to do the following:

<br />
ofstream printer;<br />
printer.open("LPT1");<br />
printer << "Hello World!" << '\n';<br />

And when your done streaming text to the printer you can try sending a control character of 0xC which was the old ASCII Form Feed[^] or (FF) character.

Is CSocket a blocking socket ?

Hello Friends,

I am been using CSocket in my application. But i want to know is CSocket a blocing socket or non-blocking socket, and what are the differences between them ?

Hmmm MSDN->CSocket[^]

CSocket Class MSDN wrote:
A CSocket object also provides blocking, which is essential to the synchronous operation of CArchive. Blocking functions, such as Receive, Send, ReceiveFrom, SendTo, and Accept (all inherited from CAsyncSocket), do not return a WSAEWOULDBLOCK error in CSocket. Instead, these functions wait until the operation completes. Additionally, the original call will terminate with the error WSAEINTR if CancelBlockingCall is called while one of these functions is blocking.

See Windows Sockets: Blocking[^]

CSocket is a high-level wrapper for a socket (SOCKET). To you, it's always blocking. Whether
the underlying SOCKET is in blocking mode or not is handled by the CSocket implementation.

For a non-blocking socket you can use the CAsyncSocket class or use Winsock APIs directly.

"Add Event Handler" greyed out in VS2005

Hey there. Can anybody tell me why, when you create a dialog app in VS2005 if you right-mouse click on the dialog in the resource editor then "Add Event Handler" menu option is greyed out? I want to be able to add OnInitDialog and OnPaint handlers to this dialog but cant!

If i drop a button control on the dialog through, and right click on that, then that works!!

thanks in advance.

To add non-control message handlers, you have to go to the source file, and place the cursor on the closing message map macro, and then go to the properties pane. At that point you hould be able to add the handler for that message.

Thanks for the tip, not that I will remember it, just seams easier to write it out.

Yeah...

This goes a long way to reinforce Microsoft's claim that they are eager to support their C++ developers. The 2005 IDE sucks if you're a MFC programmer. I seriously doubt that ORCAS would add any usability for us...

You can also just click anywhere within the class definition in the .h file, and then go to the properties pane.

OnKeyDown and OnPreTranslateMsg() problem...

Hi,
I'm facing a problem which i don't know how to solve...
I created a dialog which contains several edit boxes.
When activating the dialog , the first edit box automatically receives the input focus.
My problem is that I need to receive the ON_WM_KEYDOWN in the parent dialog,
but since the focus is on the first edit box - I will never get it.
I tried to catch the ON_WM_KEYDOWN message in PreTranslateMsg , but
I'm facing the same problem.

Anyone???

With best regards,
Eli

If you want to monitor when the text in the edit box changes, you could do something with the EN_CHANGE notification which is sent when the text in an edit box changes..

If you want to monitor keyboard messages, then i'm not sure that the WM_KEYDOWN message is applicable to dialog boxes.. You could try creating a window using the CreateWindow() or CreateWindowEx API, then programatically creating the controls, and then testing for the WM_KEYDOWN message..

Hope this helps!

Hi PerspX ,
First,thanks for your quick reply.
What is the difference between creating the control during the design time
and during runtime(the control is being created in a different way???).
Anyway,My problem is not catching the messages in the control,
but catching the messages in the dialog...

Thanks again,
Eli
