i am overriding wndproc an handling the wm_command and wm_notify message appropriately.
in the case statement of wm_notify this is what i have
case WM_NOTIFY:
nmhdr = (NMHDR*) lParam;
notificationId = nmhdr->code;
if(notificationId == NM_CLICK)
{
AfxMessageBox(_T("CLICKED"));
return FALSE;
}
else if(notificationId == NM_DBLCLK)
{
AfxMessageBox(_T("double CLICKED"));
return FALSE;
}
...
....
//more if else goes here
else
{
// call default
}
the flow does enter this switch statement but never invokes the appropriate handler. When i tried to get the value of the notificationId it shows some junk value though nmhdr is properly initialzed and the controlid that generated the message is correct. what am i missing?
thanks

I am unsure how to start solving this problem.
I though i would begin by using the Knuth-Morris-Pratt string matching
algorithm does any one have a sugestion as to where i should begin.
Input would be the Filename: wordfind.in
The input file consists of a square table and a list of words. A blank line follows the table and then the words to find, one per line.
This is a sample of what my file contains.
cenad
aatps
rnrpj
hello
wmneo
hello
apple
car
me
men
ran
woman
Output
Filename: wordfind.out
This is what I wish my program to do after the program is run:
hello (3, 0) E
apple (0, 3) S
car (0, 0) S
car (0, 0) SE
me (4, 1) N
men (4, 1) N
ran (2, 0) NE
woman NOT FOUND

Hi
I am a newbie to C++ programming and am wanting to get three user inputs from the screen. If i use 2 char variables and an int variable my programe goes through the three screen prompts asking for the input data. But if I change the first input to a char variable[20] and use a getline() function it displays the first prompt but does not stop for user input but continues to the second prompt waiting for user input.
How can I retrieve text from a user input like "Car" and the a second prompt for number plate "WWW111" for example?
Thanks

cin should do this for you ? Have you tried using a std::string instead of a char array ?
#include <string>
#include <iostream>
using std::cin;
using std::string;
using std:cout;
int main()
{
cout << "type it in";
string s;
cin >> s;
cout << "You entered : " << s;
}
That's from memory by a guy whose C++ is VERY rusty. But I think it should work.

This worked for me, unless I misunderstood your problem:
void main( void )
{
char m[20];
int a, b;
cout << "Char ";
cin >> m;
cout << "Int a ";
cin >> a;
cout << "Int b ";
cin >> b;
cout << "Char " << m << endl;
cout << "Int a " << a << endl;
cout << "Int b " << b << endl;
}

Hi!
I'm going nuts here! Spent a whole week building three huge classes and now got a bright idea...What if I was to organise my classes, def in headers, say cls1.h cls2.h cls3.h (by the by got implementation files .cpp's  ),
into a neat monster class clsMonster.h!
If you didn't understand what happened just now dont worry I still cant figure out why I even had the thought in the first place!
The thing is I got these 3 classes that logicaly are a part of a thing that can be a big class on its own. I started developing them separately since they are big but now feel that they would be neater if there was one class containing them sub classes (just jaming every member in clsMonster would be overkill and give me 2000+ lines to debug in one pile!  ).
I made a new header, defined the big class but now need to access the members of sub classes from main() thru the big class.
Problem: Cant figure out the damn syntax of accessing the members of sub classes.
eg.
....
#include "cls1_H.h"
#include "cls2_H.h"
#include "cls3_H.h"
class Player
{
blah blah
};
.....
#include "Player_H.h"
main()
{
Player myChar;
myChar.blah blah(); // this would access members of Player
}
BUT HOW DO I ACCESS THE HEADERS INCLUDED IN Player.h???
Is there an other way to do this! (main concern - neat groups!!!)
If anyone is on this particular line right now, THANKS FOR YOUR TIME!

Sorry but your question makes no-sense at all.
Can you give an example of what is in cls1_H.h that you are trying to access. The blah blah in Player is a little confusing. A real example would be more helpful to diagnose your issues.

First problem. Try to design your structure so your classes are lightweight.

That's NOT neat, it's a 'monster', a maintenance nightmare.

Forget it! I think I was sleepwalking ystrday or somthn.
Figured the whole thing out. By the way classes are so big due to enums, got lots of them!!!

Generate files
How can we generate files.
for example if I want to make an exe file that generate another exe file.
and if i make a program and put an edit box, and when i write something in the edit box, and click generate. the value in the edit box will be edited to the generated exe files
or
if i have an exe file that have an (m_value) Cstring
and make another file to edit/change (m_value) Cstring
is it possible?
thanks alot

You've got one. It's called a compiler 
Dody_DK wrote:

Your compiler does this also. You can take a string and shove it into a file easy enough, it's 'generating' an exe that is the job.

You need to define a process to do this, your two processes need to communicate and cooperate to achieve this.

you misunderstod me
I know that the compiler make the exe programs
but I mean to make a program let's call it "one.exe" and in this program are some edit box, when i write some values, i want it to be saved in other exe file with these values... i hope i explained it better this time : )
thanks alot

Your request sounds a lot like this one.

I know what you want, it just sounds wierd. Why do you want to do this ? Is it to patch another program, or is it to hack it ? Either way, it can be done, so long as you're willing to sit with a hex editor and work out exactly at what position you need to insert your new value.

I am having problems running .exe files. I am trying to run a .exe when the user clicks on a button. Could anybody please tell me the exact code which i could write in the Message Handler Function.

ShellExecute or CreateProcess(Ex)
Have a look at MSDN or Platform SDK.
Don't try it, just do it!

if you are using regular win32 api, i assume you already have a message handler for the parent window no?
if so, then you need to add a WM_COMMAND case
and test if the HIWORD() of the lParam is == BN_CLICKED and if (HWND) lParam == YourButtons_hWnd
if so then run the app
now if you are using MFC then do this
goto the dialog designer, double click on your button
and insert the code to run your app
|
|

|
|
Use either of the following API -
1> ShellExecute
2> CreateProcess
Check on msdn.microsoft.com for further details on these API
Hope this helps

Have a great day ahead!

how do you start to write an application or how do you just write one, the source code that is, and does any one have a copy that I can look at.
|
|
|
|

It really depends on what type of application you want. MFC (Microsoft Foundation Classes), ATL (Active Template Library), Console, WTL (Windows Template Libray), and there are different types of each kind too, dialog based, document/view, etc...
The simplest way is to start up Visual Studio and then do a File->new and create a new project of the type you want. If you can give abit more information like "I want a program that is like notepad" or "I want to make a command line program" that would help define how you start to make it.

I want an application that will allow me to chose any text, file folder or line I type in to be encrypted and then be able to pick an ecryption program off my choice
|
|
|
|

It soulds like you might want something graphical to make it easy to use. I personally like to use dialog based applications for things like this. So what I would suggest is that you start an MFC project in visual Studio and make it dialog based. Then you can add the buttons and textboxes to do the searching for files, or folders and then have another button to start up your encryption program. That should probably be stored as a configuration setting in either the register or some external file, ini or xml. You should probably also put on the standard menu on the dialog and add things like options, and exit.
It might be simpler for you to have separate input sections on the dialog for text files, folders and freely entered text. This way itwill not confuse the person using the software.

If possible can I pic your brain one more time?
What would I use if I wanted to start writing a application program that would run using voice activation

I am trying to create some common controls on windows ce. This is what i am doing.
m_tooltip= new CToolTipCtrl();
m_tooltip->Create(this);
m_tooltip->AddTool(button1,"Test Button");
m_tooltip->Activate(TRUE);
this is a code snippet from OnInitDialog(). Ihave included the headers afxcmn.h and commctrl.h but i still get the following compile time errors. Anything else i need to include
error C2512: 'CToolTipCtrl' : no appropriate default constructor available
error C2027: use of undefined type 'CToolTipCtrl'd:\Program Files\Windows CE Tools\wce420\STANDARDSDK_420\mfc\include\afxstat_.h(337) : see declaration of 'CToolTipCtrl'
and more all related to the common controls.
thanks,
