I have a SDI application. My view is split into 2 parts. One of these windows is a List View. The user has the possibility of adding an item in the list view from a dialog.
My problem is that I don't know how to get the information of the list view to call the function which to add items.
I tried the code below but it doesn't seem to work.
CMainFrame *pMainFrame=(CMainFrame*)AfxGetMainWnd();
CDocument * pDoc = ((CView *)pMainFrame->m_wndSplitter.GetPane(0,0))->GetDocument();
CBOFListView* prt = (CBOFListView*)pDoc->GetRuntimeClass();
prt->AddItemToList(Item); //AddItemToList is the function used to add items
Thanks
Regards!!

Try moving the creation of the dialog into a handler in the list view class. Then all you can just pass a pointer to the view to the dialog in the dialog's ctor.
CYourDialog wndYourDialog ( this );
Where your dialog's ctor looks something like this;
CYourDialog::CYourDialog ( CYourView * pView ) : m_pTheView ( pView ) {}
Then just add the items to the view from the dialog throught the pointer to the view.

Hi. When I'm trying to AddItem to ListBox which is in the Modal Dialog, I get
a Run-Time Error.
I'm really stuck, because it works allright with Modelles dialog.
Thanx in advance

First) How you construct your ListBox.? In what event?
Second)Please write part of the code....

Hello, the codegurus around the world.
You should understand the diff bet Model and Modeless Dialog.
Modeless dialog never stops the main process, but Model Dialog
stops the main process like the message box.
So, this means that you must add the item to ListBox on Model dialog
by OnInitDialog, or you can use timer or thread code in Model dialog to add the item to ListBox outside of OnInitDialog when you want to add the item
to ListBox from the control outside this model dialog.
Or you can create the model dialog by the different process, and get CWnd
of this ListBox, you can add the item to ListBox from any application.
Have a nice day!

I have rarely used any STL in my 2 years of c++, but I wanted to learn a bit more about it, so I started by reading the one chapter in Deitel and Deitel on it. But my first example from that book generated a bizare error in MSVC. Does MSVC support STL properly and do I need to do something especial? Or is
my book too old and the STL standards changed too much since this book was written in 1997.
Here is the code:
#include <iostream.h>
#include <iterator>
using namespace std;
int main()
{
cout << "Enter two integers.";
istream_iterator< int > inputInt( cin );
int number1, number2;
number1 = *inputInt; //read first int from standard input
++inputInt; //move iterator to next input value
number2 = *inputInt; //read next int from standard input
cout << "The sum is : ";
ostream_iterator <int> outputInt(cout);
*outputInt = number1 + number2;
cout << endl;
return 0;
}
And here are the 2 errors:
Compiling...
main.cpp
c:\C++\STL\Fig205\main.cpp(14) : error C2664: '__thiscall std::istream_iterator<int,char,struct std::char_traits<char=""> >::std::istream_iterator<int,char,struct std::char_traits<char=""> >(class std::basic_istream<char,struct std::char_traits<char=""> > &)

Hey guys
I want to use a file to store settings for my program preferably an ini file. Are there and API function that control writing and reading to and from ini files so all i have to do is put the data in rather then having to worry about the layout.
Cheers

WritePrivateProfileString() and GetPrivateProfileString() does what you want.
Why don't you use the registry instead?

And don't forget the GetPrivateProfileInt() and WritePrivateProfileInt() functions.

The functions mentioned previously are provided by Windows for backwards compatibility. You should use the registry unless you have compelling reasons not to, such as a huge amount of data to store and you don't want to bloat the registry (like it needs your help), or you want users to access and modify the file.

One simple Question:
I have a HWND from a window found by EnumChildWindows.
It is an edit-control.
How can I get the text of this window?
GetWindowText does not seem to work, the MSDN says as follows:
If the target window is owned by the current process, GetWindowText causes a WM_GETTEXT message to be sent to the specified window or control.If the target window is owned by another process and has a caption, GetWindowText retrieves the window caption text. If the window does not have a caption, the return value is a null string.
i.e., since the edit-control I have found belongs to a different thread, the returned window-text is always null.
How can I get the text?
SetWindowText also doesn't work, because the Window belongs to a different thread.
any suggestions?
thanks

Maybe the hilighted text from MSDN refers to non-child windows, that can have a caption. An editbox doesn't, and since sending a WM_GETTEXT can't work for another process, the function fails and returns zero.
Just supposing though, I'm not sure

I was just working on a program that needs to do what you are asking. The problem here, is that you do not know how much text is in the control in order to read it. To exaserbate the problem further, you cannot get a pointer to the buffer that holds the text, because different controls keep the text in different places.
The solution is to send a pair of messages to the window you want to extract text from. The first queries the window for the size of the text it contains, and the second retrieves the text. Some sample code:
int len = ::SendMessage( hWnd, WM_GETTEXTLENGTH, 0, 0 ) + 1;
TCHAR* text = new TCHAR[len];
::SendMessage( hWnd, WM_GETTEXT, len, LPARAM( text ) );
delete[] text;
Adding one(1) to the length is important, because the WM_GETTEXTLENGTH message does not include the terminating null character in the length. Using the TCHAR type will allow your code to compile on both ANSI and Unicode environments.
One caveat: You cannot extract the text of a password-protected edit field on Win2k and WinXP. Microsoft finally plugged that little security problem

Hello, I'm really new to C++ and windows programming trying to teach it to myself. so I picked a simple and silly project, I'm trying to write my own keyboard drivers for the special shortcut keys on my keyboard. I only say driver for lack of a better word, as I really have no intention of using DDK, I simply want to use a windows hook to redierct them but I can't fiquire out how to the OEM scan code out of the lParam of KeyboardProc and the they aren't defined as virtual-keys (I assume because the manufacturer seems to be using a hook as well) any help would be appreciated
Thanks,

I'm working on a program and I need the back ground of my static tect controls to be black and the text to be White. How whould I go about making these changes??

Thanks, that answered my question about the background color, but id does not help me with setting the static text text color ... any suggestions.
Thanks ~

Read up on the CDC functions (or equivalent Win32 APIs if you're not using MFC). SetTextColor will, as the name says, set the text color.

ok so i make an app shell and put in a flexgrid control.
the grid is 7x7
here's my prob:
-the first column is static, never changes. i need to put in 7 labels.
-the second column will change, it contains dollar values i.e $400.00. the information in this column repeats itself across the span of the remaining columns.
-i need 1 button to display the dollor values and 1 button to clear them leaving the first column unchanged.
i've tried useing an example for this but it uses a random generator and i can't get the items to appear in the order i want them in. please help!!

I have a Win32 application which has a toolbar, dropdown menu, and utilizes hotkeys.
I enable/disable buttons on my toolbar/menu based on certain criteria which is changed during program execution.
Where is the best place in my code to tell the toolbar/menu to make desicions about enabling/disabling buttons? It seems a bit messy to call my Toolbar_Update() function everytime something is executed from the menu or toolbar.
Is there some kind of call back or something I could use?
I mean, calling this Update function everytime does the trick, but I'm not sure that its all that clean.
Mike.
