? Missing connect step(s), who do you have connecting to whom (seeing as you have both 'client' and server listending) ?
Generally you don't have the 'client' accepting, it initiates the connection to the server and the server then uses that new connection to talk to the client.

Sorry, but there are too many unknowns to provide much help at this point. I use IOCP and AcceptEx in my server code and IOCP in my client code and i haven't had any problems like this.

Yeah.
The problem is so weird. Yes, the server does make a connection to the client and the other way around. That is how AcceptEx() returns a valid socket.
I just cannot figure out why once IOCP dispatches a new incoming socket, that socket cannot be used to send or receive data. It is almost like there is a step or two missing. In other words, there is an API call that needs to be made to an incoming AcceptEx() socket. Yes, I implemented SO_UPDATE_ACCEPT_CONTEXT. The problem remains.

I am using a common edit control for the purpose of displaying output in text format in my application. Every time I need to write something to the screen I find that I need to put the contents of the edit box into a string put the new output into anothor string, concatenate these two strings togethor and then output this new longer string to the screen. For simplicities sake isn't there a way to just call a function similar to idcoutput->SetWindowText(); that will add text and not overwrite the box with the new text?
Thank you,
Eric Sepich

If you're using CStrings there is a function called 'Append' that lets you add to a string.
From the looks of it you aren't using DDX so you're still going to have to call SetWindowText in order to set it, but the append function will allow you to just add to the string. Not sure if this is the case for strings other than CStrings, but I bet any type of string has this functionality.

CHARRANGE crEnd = {-1, -1};
SendMessage(hwnd, EM_EXSETSEL, 0, LPARAM(&crEnd));
SendMessage(hwnd, EM_REPLACESEL, FALSE, LPARAM(pszText));
Your class library of choice probably wraps those messages into something prettier, but that's the plain SDK version of what you are looking for.

we know:
{
TCITEM tcItem;
tcItem.mask = TCIF_TEXT;
tcItem.pszText = _T("as");
m_TabShow.InsertItem(0, &tcItem);
tcItem.pszText = _T("df");
m_TabShow.InsertItem(1, &tcItem);
}
can create a TabCtrl...
but how to disable a item of TabCtrl? use m_TabCtrl.SetItemState()??
thanks...

I'm not sure it's possible, and it would be strange for the user to click on a tab without getting any action done.
SO IMHO there are two solutions:
1) remove the tab
2) disable the controls contained in the tab.

Hi,
I have written a server program which uses a set of APIs. I have managed to get the server to do what is required now the next step is to make this server run as a service. I have tried such things as XYNZservice and srvany and they will indeed run the server up for me however when I try to connect a client to the server the server will bomb out. If I run the server as a normal executable I do not have any problems. I have modified the services login to be the same as the login I used. PLEASE any help will be appreicated......
PS I have very little experience with MS development tools so a hand held approach would be nice.

Services are really too big a topic to discuss here. I suggest a book: Programming Server-Side Applications for Windows 2000[^], by Jeff Richter and Jason Clark (MS Press).
SRVany and similar programs don't really run your program as a service - they only start up a copy of your program in the service's security context when the service is started, and kill it off (with TerminateProcess, IIRC) when it's stopped.

I'm a beginner writing my 2nd program. I'm stuck. I'm not sure were the problem is. Monthly payment formuls: payment=rate*(1+rate)n/((1+rate)n-1*L rate=monthly interest rate, n=number of payments L=loan amount.
//Patrick Comeau
//Monthly Payments
//Project 2
//oct 1 03
#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;
int main()
{
float rate = 0.0; //monthly interest rate
float nop =0.0; //number of payments
float loan =0.0; //amount of loan
double pay =0.0 ; //monthly payment
double apb= 0.0 ; //amount paid back
double intpd = 0.0; //interest paid
double num =0.0;
double den=0.0;
cout<< "What is the loan amount " ;
cin>> loan;
cout<< "The number of payment is " ;
cin>> nop;
cout<< "What is the monthly interest rate " ;
cin>> rate;
cout<< "The Monthly payment is " <

I'm not gonna give you the answer to this because its way too obvious which is why there probably hasn't been a response yet.
Here's a hint. Check out your last three cout statements and think about what they are doing. Shouldn't take long to see the problem.

You really want to consider Cout'ing pay, apb, and intpd AFTER YOU HAVE CALCULATED THEM.

Hi,
I have written a SDI application which opens a XML document from the file->open menu and works on it. Now, I want to right click on any xml file and go to the option "open with" and select my SDI application from the list, and the application would show data from the xml file the way it works for the file->open menu. How can do that?
Please advise.

Sorry for this question in the c++ forum, but people don't reply in the general discussion forums. Is Intel planning on releasing a 64 bit processor as well anytime soon? How long until they might be available for notebooks? Thanks!
By the way...I have to write a program for my class, it's supposed to display "Hello World". I'm a dumbass who doesn't want to do any work, so will everybody on here do my homework for me so later I can help flood the job market with yet another unqualified candidate? Lol, thanks!

Lol, the program part was a joke.
Know anything about the processor question?

Intel 64-bit processors have been available for 3 years. Current available one is the Intel Itanium 2 Processor.

Hello,
I am just trying to upgrade a MFC project to VS.Net 2003. In this project I have an ActiveX Control for which I created a wrapper class using menu "Project | Add to project | Components and Controls" in VC6. After selecting the correct control this created or recreated the corresponding wrapper class to use the control in an MFC-Dialog.
May be I am stupid, but I can't find the corresponding command in VS.Net 2003. 
Any help to find this silly command is very much appreciated

Right-click the Toolbox, choose Add/Remove Items from the menu. In the Customize Toolbox dialog that appears, choose the COM Components tab. Check the box alongside any components or controls you want to reference in the project.
Drop any desired controls onto your dialog resource.
When you add a member variable for the control (right-click the control and choose Add Member Variable), VS.NET prompts you for the files for the wrapper class, along with the other information.
Alternatively you can simply right-click the dialog resource and choose Insert ActiveX Control (which, for some reason, produces an entirely different dialog).

I noticed this context menu element, but did not expect to (re)create the wrapper class here.
Thanks a lot for your help
