I have a dialog with a start button and I want to add a listen function on it. Below is the code that I try:
void CTCPTestDlg::OnBtnstart(LPVOID lParam)
{
// TODO: Add your control notification handler code here
}
When I compile, ot occur a error:
error C2511: 'OnBtnstart' : overloaded member function 'void (void *)' not found in 'CTCPTestDlg'
I don't know how to solve it. can somebody help me

check your declaration in the .h file
most probably you have a different declaration there.
void CTCPTestDlg::OnBtnstart(LPVOID lParam) in .cpp
afx_msg void OnBtnstart(LPVOID lParam) in .h (if function is auto-generated)
void OnBtnstart(LPVOID lParam) in .h (if function is manually generated)

Hi..
how can i select excel cell by index not by name using automation? e.g. cell(1,2) for B1 cell. in VB i can use cells(1, 2) coz it's treated as an array of cells. but in VC++, i got error if i use cells[1][2] to access the cell. There is no such cells( 1, 2) method either. The method available is only Range("B2") which is using cell's name not cell's index. Help.. urgent..
Many Thanks..

I wanted to make a vb application which would dial a telephone number using
the modem. When the person on the other end lifts up the telephone (answers
the phone), the application should start playing an audio file(eg. .wav
file).
The approach I took was using the Tapi. As my modem is connected to the
serial port on my computer I send AT commands to make the phone call . This
is working fine and the call is being placed.
I wanted to know whether this is possible at all? Whether I am approaching
the wrong way? If it is possible, then please give some suggestions or
samples(vb or vc). If it is not possible , then what is the best way to do
so

How to solve this error?
Error C2065 : 'ReadPortNo' : undeclared identifier

Where did you declare it ? It's obviously not visible to the code that tries to use it. Post some code so we can see what's going on

int SOCKADDR_IN; <---this is I declare when it occur the error :'SOCKADDR_IN' undeclare identifier
UINT ListenThread(LPVOID lParam)
{
HANDLE hThread;
SOCKADDR_IN SktAddr;
char szMessage[300];
wsprintf(szMessage, "(ListenThread) - Starting TCP/IP Initialisations.");
WriteSysLog(szMessage);
return 0;
}

Did you mean to put typedef in front of this ? Or perhaps #define SOCKADDR_IN int ?
As it stands, you have a global int called SOCKADDR_IN, and you're trying to use a variable name as if it were a type.

I am a straight-up newbie to Visual C++ .net. The problem I have today is that I have typed in some code. It runs it fine. Then I make some changes, and it just continues to compile and execute the old code - even when I erase every single visible peace of code. It's driving me nuts. It just started doing this today. Is this some glitch or did I mistakenly tell it to just run the first code I compile no matter what I type. Any (and I mean any) help you all can provide would be appreciated, especially since I am very, very frustrated right now.
Thanks in advance for your help.
Sincerely,
BP
It's just a matter of time!

Try 'clean' ( which erases your old compilation files ) and then 'rebuild all'. This shouldn't happen, but that's how you fix it. If that doesn't work, go into the directory you're building in, and delete everything by hand. Then the compiler has no choice but to recreate it.

Why is it not seeing the IActiveDesktop Interface in shlobj.h. I tried using other interfaces in there, and they work fine, but the IActiveDesktop interfaces are the only ones that dont work.
When I try to compile the following code I get an error:
error C2065: 'IActiveDesktop' : undeclared identifier
#include <shlobj.h>
#include <string>
#include <wininet.h>
#include <windows.h>
#using <system.dll>
#using <mscorlib.dll>
using namespace System;
using namespace std;
int main()
{
HRESULT hr;
IActiveDesktop *pActiveDesktop;
hr = CoCreateInstance(CLSID_ActiveDesktop, NULL, CLSCTX_INPROC_SERVER,
IID_IActiveDesktop, (void**)&pActiveDesktop);
...

Include <wininet.h> before including <shlobj.h> and make sure _WIN32_IE is defined to a value greater or equal than 0x400

Thanks
now unfortunately the hr function
hr = CoCreateInstance(CLSID_ActiveDesktop, NULL, CLSCTX_INPROC_SERVER,
IID_IActiveDesktop, (void**)&pActiveDesktop);
is not setting up the ActiveDesktop and hr is returning failed,
how do i initialize it so that i can use pActiveDesktop?

Did you call CoInitialize ?

Always look at the HRESULT value. Then do a look it up in the system header file called winerror.h. The header files are documented.

I'm still struggling with this project, getting it to link to DCMTK. I want to change my MFC app from linking to the multithread dll to just multithread. However, I get this message:
Please use the /MD switch for _AFXDLL builds
I cannot find code that #defines _AFXDLL, or any thing else that would cause this to be defined. How do I change this ?

Configuration Properties, General, "Use of MFC". Change it to "Use MFC in a Static Library"

I'm going to patent thought. I have yet to see any prior art.
