Visual C++ :: Send Message - Receive / Respond
Jan 2, 2014I have a problem in a c++ project. I have created a .dll file and hooked to an .exe
I want this .dll to make a ping or to send a message like hello somewhere, and IF ping or message doesn't receive an answer that's means the user has suspended-terminated this dll from the exe then the exe will close. How can i do that?
C/C++ :: Send Message From Server To All Client?
May 30, 2014First of all i create single server single client program and then using thread i make multiple client to connect to server.
while(true){
csock = (int*)malloc(sizeof(int));
if(nClient<=maxClient){
if((*csock = accept( hsock, (SOCKADDR*)&sadr, &addr_size))!= INVALID_SOCKET ){
[Code].....
The clients send message to the server and server echo back the message to that particular client. But i want that the server will echo back ones's message to all clients. Suppose 5 clients are connected to the server. So whenever one client send a message to the server, the server will send that message to all 5 clients.

Oct 7, 2012Have tried to track down the delay? Which function takes that long? Have you printed some logs or measured the time of the functions? No I am not sure how to do that! I debugged it but i didn't see any difference! I definitely think its the logic in the receive code that's "inefficient" what do you think about that? Do you think there's a more efficient way of receiving messages and sending them? Because what I am doing is receiving one then calling send and sending that message out to all users then receiving another one then calling send and sending it out to all users and repeating that process till all the messages are sent, both methods are using a loop to send to all users. DO you think i should receive all messages then send them all out at once? or is that less efficient?

Visual C++ :: How To Get Rid Of Not Responding Message
Jul 30, 2014I have a simple dialog based app that performs some time consuming file manipulations. The activating method contains the customary
Code:
CWaitCursor wait;
The hour glass initially appears, than after a few seconds, the dialog title bar indicates 'not responding'.
This is misleading to users as it suggests the application has ceased to function when, in fact, it's working just fine. I would like very much to eliminate this 'not responding' message but havn't a clue how to do it. Have any of you dealt with this problem, if so, how?

Sep 28, 2014You place a breakpoint at one of locations within the message loop. But I want the breakpoint to trigger when I click on the application window, for example. But I can't, it went so fast so long as I switch from VS to the application program, the breakpoint is hitted again, then the application is frozen again. I don't know how to setup a conditional breakpoint.

May 31, 2013I'm looking for a resource (possibly CPP) for which I could do the following on a windows and linux machine:
1) type a string message into a GUI control (or some other input that can be accessed by the resource).
2) run a resource script that puts the message through a hash function (or a custom hash function) and outputs the hash string.
3) have a reverse function available in order to decrypt the message in an input fashion just like step #1.
what open-source resource might be the best for this? Right now I am imagining typing a message into a text file, saving the file to a hard drive location, running a script on it replacing the old file with a new file that just has a hash string in it, then using that hash string for the encoded message.

Visual C++ :: Receiving Windows Message In Console Application?
Oct 11, 2013I'm trying to write a program that passes Windows messages back and forth from another program that controls a laboratory instrument. I was able to write a program that successfully passes instructions, as evidenced by the instrument doing what I tell it. However, I am having trouble getting a return status from the instrument. The manual instructs the following:
// demo code, etc.
// send message to the instrument operating software here...
SendMessage(hwnd, WM_COPYDATA, tag, (LPARAM) &cd)
Either a completion message or return data is returned. Remote commands ReturnStatus, ReturnTiming, and ReturnData return data. In either case, data is received through an asynchronous windows message inside Win32 COPYDATASTRUCT type data packet.For example, a typical OnCopyData window callback is shown below, where the string data retrieved is finally stored into a Microsoft CString object. Note the use of variable replyTag, discussed above, which is used to isolate the correct windows message returned.
BOOL CUserDlg::OnCopyData(CWnd* pWnd, COPYDATASTRUCT* cd) {
….
if (cd->dwData == replyTag) {
/* String pointing to status */
CString retStatus = (char*) cd->lpData;
}
….
}
I can't tell if my problem is in generating the replyTag, getting the HWND to my own console window, or the actual receiving part of the code.
When setting the replyTag, the manual instructs: UINT replyTag = RegisterWindowMessage(“SOFTMaxProReplyMsg”);. However, I have to put an "L" in front of the string or I get a data type error (can't convert const char* to LPCWSTR).
When setting a HWND for myself, the manual instructs: HWND MyWnd = GetSafeHwnd().
That produces an error because GetSafeHwnd is a function of the Cwnd class, and I don't have a Cwnd. I have replaced it with HWND MyWnd = GetConsoleWindow();
When listening for the reply message, the manual instructs what I quoted above. However, I again don't have a Cwnd. I therefore simply used
if (cd.dwData == replyTag) {
CString retStatus = (char*) cd.lpData;
}
The above if statement always evaluates false, and the cd.lpdata contains the message that I had sent out instead of a reply message. How to get a reply using my console application. Here is the full code of my function:
Code:
#include "stdafx.h"
#include<iostream>
#include<vector>
#include<string>
#include<afxwin.h>
using namespace std;
void SendCommand(string command) {
// Get tags to identify the receiving and sending messages

Visual C++ :: MFC- Receiving Button Click Message Failed
Oct 2, 2014I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent)
2. click on on any place of the application, but not on the dialog.(removing focus from dialog)
3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ...
2. ...
3. click on the dialog area just to set focus on the dialog again
4. click again on buttonX. (result ok, OnBnClicked message is sent)
**I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code:
class CToolsDlg : public CBDialog {
DECLARE_DYNAMIC(CToolsDlg)
public:
CToolsDlg(CWnd* pParent = NULL); // standard constructor

Visual C++ :: MFC Proper Usage Of Sending Message To Dialog To Activate
Jan 7, 2015I have finally got around to developing C++ & MFC using Visual Studio 2012, to build a full GUI Windows application (not sure if I have made the right choice). Though admittedly in two months time I do have a dialog window at my beck and call.
Now I have discovered a flaw (suspect) partially caused by the design of this program not all following the same principles, nor written by the same people and long predates me. Let describe the situation.
I have a dialog I have created as a class which has a combo box. The list of items are populate during the OnInitDialog() function just fine, except if the file where the detail is not yet read from that combo box would not have any items other than the default. This is to be expected in the use of the program, so fine.
However, if the dialog (modeless) was already open and active, when the user went up to and selected the menu command (main window) to read that file that CPtrList data structure that held that data would not populate that Combo box on my dialog.
So what I would like when I am done reading the files contents is to detect if my dialog is opened and if so send it a message to Activate (force a call to OnActivate()). I have gone to the event list for the dialog and exposed this event handler from the resource editor just fine.
I see the syntax of OnActivate() is
void MyClass::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimalized);
So nState is an Unsigned Int of the current state of the thread/window (not sure)?
CWnd* pWndOther is the CWnd of my other Window that wants my dialog to activate I think which is the main application since it was on the a menu that this function was called to read the file.
bMinimalized is whether my dialog is mimalized(?)
