I have an app which is a Dialog app. It then opens another dialog when I press a button. Now what happens is that it receives information via TCP. Both the dialogs have List controls.

When the TCP info comes in, the Main Dialog which has the object of the 2nd dialog, then takes the information and neatens it and says add the information into the List control of the 2nd dialog like this:

2ndDialog.m_list.AddString(information received).

This gives an ASSERTION FAILURE as in the subject. How can I fix this?

The list box in the second dialog has not been created yet. Has the dialog been opened yet? If not, then you can't add strings to the list box.

Well the listbox, is declared in the class of the dialog. Okay, the dialog is not opened at that stage. I will try opening it then, and then try DoModal. But I know if will fail at the point when I try AddString. Let me test first then tell u......

DoModal works fine. But now its all a matter of adding to the list when the dialog is opened. Lets try that.

It does not work at all.

2ndDialog.DoModal()
takes away the execution from the main dialog, so I am not able to addString from the main dlg.
How else can i do it?

Make an array of strings in your second dialog that the first dialog can add into, then in the second dialog's OnInitDialog() function, add the strings from the array into the list box. CArray will be fine.

Well, I understand the OnInitDialog is not defined, only as virtual funtion it is defined. Now if I do use that function, without defining anything, the system crashes.
Problem is that the ListBox seems to be in the wrong context. This inevitebly causes the assertion fail. I hope that is correct reasoning though.

How does one use a richedit control, without using a richedit view?

Ohhh! Thanks I now understant your explanation. I need to define the OnInitDialog function. I see. And then I do what I need to do now.
Thanks

Most of the documentation you will find on ADO is in Visual Basic. When I learned I had to learn how to translate Visual Basic examples to visual c++. There is a class library on this site that uses ADO:

The names suggest that they are wrapper for the Collection property.

inline _variant_t Recordset15::GetCollect ( const _variant_t & Index ) {
    VARIANT _result;
    VariantInit(&_result);
    HRESULT _hr = get_Collect(Index, &_result);
    if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
    return _variant_t(_result, false);
}

inline void Recordset15::PutCollect ( const _variant_t & Index, const _variant_t & pvar ) {
    HRESULT _hr = put_Collect(Index, pvar);
    if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
}

I suppose the valuje of Index depends on the context of the Collection

Problem including commctrl.h.

I always get these two errors when trying to include commctrl.h in my application.

c:\program files\microsoft visual studio\vc98\include\commctrl.h(26) : error C2146: syntax error : missing ';' before identifier 'HRESULT'
c:\program files\microsoft visual studio\vc98\include\commctrl.h(26) : fatal error C1004: unexpected end of file found
Error executing cl.exe.

I've added comctl32.lib to the list of library modules in my project settings, but it wouldn't resolve the problem. I use MS Visual C++ 6.0.

Any ideas?

Cheers, Blackmesa.

Your problem has nothing to do with linker settings. The problem is that you need some header included before commctrl.h. What type of project is this MFC, ATL, Win32 API... ?

John

blackmesa4-Jul-03 4:34

It's a WIN32 API project.

Do you have #include <windows.h> before #include <commctrl.h> ?

John

blackmesa4-Jul-03 4:42

4-Jul-03 4:42

The first #include in the incriminated file concerns commctrl.h, as you can see below.

/**
* input.cpp
*
* Input module.
**/

#include <commctrl.h>

#include "input.h"
#include "inputvars.h"
#include "gamevars.h"
#include "layout.h"
#include "resource.h"

//.... rest of file

make sure you have included "winnt.h" or "wtypes.h" first. Does this help?

Wide iostreams

You would think that the following bit of code would produce a 6-byte file:

wofstream f( "test.txt" ) ;
f << wstring( L"123" ) ;

But it doesn't. It produces a 3-byte file. A bit of experimentation indicates that the stream seems to be converting the wide characters to single-byte before writing it to the file. This also happens using Stlport (with their iostream library).

This seems just plain wrong. Anyone care to explain why it's like this?

Curse you for making me look at the VC 6 STL code this early in the morning. Wink | ;)

The fstream inserter eventually calls basic_filebuf::overflow(), which has this line:

fwrite(_Str->begin(), 1, _N, _File)

The problem is that it writes 1 byte, when it should write sizeof(_E) [where _E is the template character type, wchar_t in this case].

I'm converting Awasu to Unicode. My life is over until further notice Cry | :((

Actually, it's not quite that bad. Most of it is ready for Unicode but there are some core modules that I wrote years ago that need to be converted. Of course, *everything* uses them...
