Do you need to call CreateInstance() on the rs object before using it?

Hi all,

In an Standard combobox you can select the items from dropdown and as well edit it..

But in an owner drawn combobox after adding the items, u can only select from drop down.
What has to be done in order to allow owner drawn combo box to allow editing as standard control?? Roll eyes | :rolleyes:

Since combo box is customized,
now u need to make a customized edit box(CEditEx),
and when you double click the combo box a EN_UPDATE message is send to CEditEx, OnUpdateEdit.

You can only edit the combo box selection if the Type property of the combo box is set to Dropdown.
If the Type property is set to Droplist you can only do selection.

The current CWnd object will not become the owner of the Clipboard until the EmptyClipboard Windows function is called.

StartProcess/Inject DLL or Detours

Hi,

I was wondering if DetourCreateProcessWithDll is just equivalent to CreateProcess suspended, injecting the DLL, then resuming? Or is it doing something special in the background, and if so, does anybody have any code not dependent on the Detours library?

Thanks

I found this reference to Detours: Notes on Detours[^]. If you use the search phrase:
"so, the deal with detours is that there are a couple different"
it will take you right to the section that explains what DetourCreateProcessWithDll is doing.
What exactly are you trying to do?

How to retrieve Public IP Address

I'm currently working on a program that outputs the information given under ipconfig/all in DOS to a text file. Now even though this seems very simple do check normally, its for people who don't know dos commands and that sort of thing. However to make this program more effective I would like to have it output the Public IP address of a network, this can be done normally by visiting http://whatismyip.com

The code is currently:

#include <windows.h>
#include <winable.h>
#include <iostream>

int main()
{
    system("ipconfig/all >> \"C:\\Documents and Settings\\gamefreak\\desktop\\test.txt\"");
}

which is working, now I'm trying to output the information provided by http://www.whatismyip.com/automation/n09230945.asp

I suppose an answer on how to copy and paste all the information from a webpage in C++ would work the easiest.

cant make it stop, problem with small c++ code

i have this problem, i am an amateur in programming c++ so i made this simple program: i have d0, d1, d2, and d3, i give them some values, then i have a, b, c, d, e, f, and g, and i want to calculate them with a math operation for each one, but that operation uses the d0, d1, d2, d3 values that you gave them before with the cin's, so, after you give the values to d0, d1, d2, and d3, the program closes itself because it finishes doing everything but i cant see the results for the a, b, c, d, e, f, and g operations. Can someone help me please.

This is my code:

#include <cstdlib>
#include <iostream>
#include <stdio.h>

using namespace std;

main()
{
int d0, d1, d2, d3;
int a, b, c, d, e, f, g;
//Meto los valores 0 y 1 de las variables d0, d1, d2, d3
cout<< "Inserte los valores de las siguientes variables:\n"<<endl;
cout<< "Variables: d0, d1, d2, d3\n";
cout<< "TIENEN QUE SER 0 o 1\n";
cout<< "Inserte d0\n";
cin>> d0;
cout<< "Inserte d1\n";
cin>> d1;
cout<< "Inserte d2\n";
cin>> d2;
cout<< "Inserte d3\n";
cin>> d3;
cout<< "Ahora se muestran los valores de cada segmento\n";
//Calculo los valores de las variables a, b, c, d, e, f, g, utilizando los valores de d0, d1, d2, d3
a= ((d0&&d2)||(!d0&&!d2)||(d1)||(d3));
b= ((d0&&d1)||(!d0&&!d1)||(!d2)||(d3));
c= ((d0)||(!d1)||(d2)||(d3));
d= ((!d0&&!d2)||(!d0&&d1)||(!d0&&d3)||(d1&&!d2)||(d1&&d3)||(d0&&!d1&&d2));
e= ((!d0&&d1)||(!d0&&d2));
f= ((d0&&d2)||(d0&d1)||(d2&&d2)||(d3));
g= ((!d0&&d1)||(!d1&&d2)||(!d1&&d2)||(d3));
//Muestro los valores en pantalla
cout<< a <<"\n";
cout<< b <<"\n";
cout<< c <<"\n";
cout<< d <<"\n";
cout<< e <<"\n";
cout<< f <<"\n";
cout<< g <<"\n";

just before the last bracket in the program, add system("PAUSE"). This will only work if you're using Windows or DOS.

I don't understand but only a few words of the Spanish and I was too lazy to check the math because I don't understand it either..(think I need to know the comment right before it)

Anyhow if you add getch(); or system("pause"); right before your final bracket that will fix the problem for you.

*notes: system("pause") should be platform dependent, but works in windows.. you have to press the enter key before the program does anything else

getch = get character, all it does it waits for any key at all to be pressed and then continues.. should work on any platform but you may accidently hit a key and close the program

its common practice to include return 0; or return 1; but as you can see, not necessary .

by the way, a suggestion: make the main() function return an int; i.e., int main(). and add return 0 to the end of the code. it's good practice.

Understanding SDI Document/View Linkage - #$@%$%%^$%^%

CodeMacDaddy8-Jul-09 8:47

I have created an SDI app with view/document architecture. Reviewing many books on this concept, I understanding there is linkage with pointers between the following:

1) Application Object to Document Template
2) Document Template to Document Object
3) Document Template to FrameWindow
4) Document Object to View Object
5) View Object to Document Object
5) Frame Window to View Object

Yes, nice concepts but how do I use these pointer, no good "real examples".
4 books later and I am still ripping my hair out. Can someone show some code snippets on how I would initialize the pointers and use these pointers.

For example in my app I have some data coming from a comm port, using a 3rd party C++ lib, a function is called when a new comm msg arrived. I would like to store this data in the Document object which would then call a Document Object method that would execute CDocument::UpdateAllViews to notify the View to get the new data from the CDocument object and update the displayed screen. How can I directly call a CDocument method that I add to my project, i.e from the function that is called with the new comm msg arrives ? My other thought is to post a message to the CDocument object which would trigger the view updating. I understand the concept of this view/document architecture just need some help in "real code" snippets. If I could just get past this concept.

lib file keeps fully recompiling even when no changes have been made

Hi,

I'm using Embedded Visual C++ 4.0 for this project so it's a little different than the recent versions of VC++ but by and large it's the same interface, albeit more similar to the older Visual Studio 6.0 from years past.

So the problem is this:

I have a large project that consists of several smaller projects. One of these smaller projects, a lib project, keeps fully recompiling every darned time I compile the project, even though no changes have been made to it. The other lib files are fine, they don't recompile unless I change one of their cpp/h files. I'm sure it's just some silly setting on this lib project but for the life of me I can't find it. Does anyone know what I can do to stop it from recompiling every time?

Thanks!

Is there some way of showing a verbose listing of what the build system's doing? It might tell you what file(s) it's looking for that's causing the rebuild?

Alternatively (and this is something I've done with VS2003/8), you could use SysInternals ProcMon to see what files the build system (msdev for eVC++4?) is accessing - you may well see it looking for files that a) don't exist, and b) aren't built by the build command for some reason.
