You need to give us some more information. From the code above it looks like you
have a pointer which you set to a new struct instance. You then point it to
a previous instance which you add to the list...? It may already be in!
You mention strings and numbers without giving us actual facts / definitions.

Try something like the following (if you like MFC):

struct Foo
{
    int nBar;
};

CTypedPtrList<CPtrList, Foo *> FooList;

Foo *f1 = new Foo;
Foo *f2 = new Foo;

f1->nBar = 3;
f1->nBar = 17;

FooList.AddTail (f1);
FooList.AddTail (f2);

Foo *f = FooList.GetHead ();
TRACE1("nBar=%i\n", f->nBar);
f = FooList.GetHead ();
TRACE1("nBar=%i\n", f->nBar);

...

There are STL equivalents to the above code, but I'm not so confident with STL to rattle
out a chunk of code off the top of my head.

My app. under Win98? Problem with DLL's

Hi,

I have programmed a MFC application under Win XP, and now i try to run my app on Win98.
I have copied the following files to the win98 system dir:
MFC42.dll, msvcp60.dll, msvcrt.dll

I get the following error:
The MSVCRT.DLL file is linked to missing export NTDLL.DLL RtlGetNtVersionNumbers

With Dependency Walker i see that the version of ntdll.dll not correct is for my app. When i copy a newer version of ntdll.dll to the system dir, windows doesnt start correctly.

Have i copied the wrong MSVCRT.DLL? Which DLL's do you normally use?

Thanks for helping me!

Willem

If you have access to the CDocTemplate objects that were registered in InitInstance you can get it like this:

pTemplate->m_hMenuShared

You can get a specific doc template by iterating the CDocManager object:

CDocManger = *pDocMan = AfxGetApp()->m_pDocManager;
POSITION pos = pDocMan->GetFirstDocTemplatePosition();
while (pos)
{
CDocTemplate *pTemplate = pDocMan->GetNextDocTemplate(pos);
// make use of the pTemplate here.
}

Updating CListCtrl using Modal CDialog

13-Apr-03 18:06

How can I pass arguments to CDialog allowing me to update a CListCtrl?

ie OnDblClick/etc, I call a modal CDialog for editing purposes, however I cannot pass arguments (ie ListItem contents to change).

Basic question - guess I am basically lost

You could pass the address of the list control to the dialog just before you call the dialog's DoModal(). For example:

void OnDblClick()
{
  CMyDialog dlg (this);
  dlg.m_pListCtrl = &listCtrl;
  dlg.DoModal();
}

Convert a char* to a variant_t

How do I convert this type.

I'm importing the CDOSYS lib, and I need to call the

pFld->put_Value(_variant_t(myconvertedtype));

the Microsoft examples use static "myaddress@something.com" , and I've not done stuff with this before.

Thanks for your help.

Sorry the proper answer is:

_variant_t vtTemp;
char* szTemp;

...
...

szTemp= (char*)malloc(100);
strcpy(szTemp,"hello there");
vtTemp.SetString(szTemp);
pFld->put_Value(vtTemp);
free(szTemp);

template (ANSI compliance) question

Hi,
The following compiles fine under gcc, but generates a compile error on line 2 in VC 7.0.9466 (error C2988: unrecognizable template declaration/definition)

template<class t,class="" alloc="">
template<class t1=""> // <------ error
CDSVectorBase<t,alloc>&
CDSVectorBase<t,alloc>::operator*=(const T1 &x)
{
...

Is this a problem with the C++ compiler, or is the code not ANSI compliant?

Thanks.

Your program is correct, it is VC++ that is failing here. You can workaround the problem by defining your function in place, if you can afford it.

IE Toolbar Problem

DuFF13-Apr-03 10:41

DuFF

13-Apr-03 10:41

I made an IE toolbar but there is just one problem. It works perfectly on my system (Win98) when I compile it. The problem is when someone else tries to install. So far its only been tried on WinXP, not sure if that is the reason. What happens is that they can see the large Toolbar button at the top of IE but not the toolbar. Nothing happens when they click the large toolbar button and the toolbar does not show up under the toolbar menu. Why is this happening??

There is one thing that I changed that my be causing this, the top section of my Toolbar.rgs. I changed both the CLSID's and ForceRemove, could this be the problem? Right now it looks like this:

<br />
HKCR<br />
{<br />
KControl.ControlBar.1 = s 'K-Control'<br />
{<br />
CLSID = s '{E0DD6CAB-2D10-11D2-8F1A-0000F87ABD16}'<br />
}<br />
KControl.ControlBar = s 'K-Control'<br />
{<br />
CLSID = s '{E0DD6CAB-2D10-11D2-8F1A-0000F87ABD16}'<br />
CurVer = s 'KControl.ControlBar.1'<br />
}<br />
NoRemove CLSID<br />
{<br />
ForceRemove {E0DD6CAB-2D10-11D2-8F1A-0000F87ABD16} = s 'K-Control'<br />
{<br />
ProgID = s 'KControl.ControlBar.1'<br />
VersionIndependentProgID = s 'KControl.ControlBar'<br />
ForceRemove 'Programmable'<br />
InprocServer32 = s '%MODULE%'<br />
{<br />
val ThreadingModel = s 'Apartment'<br />
}<br />
'TypeLib' = s '{BA246564-5224-4427-9595-CC18617AF491}'<br />
}<br />
}<br />
}<br />

If that is the problem than how can I fix it?? Please help, Thanks.

CString and std::string

13-Apr-03 8:50

I have a function that takes a std::string
void SomeFunc(string str);
I want to use std::string (instead of CString) because this function is complied for both Unix and Windows

Then in a MFC dialog program, I set a edit control to a CString. What is the best way to convert CString to std::string? Can I associate std::string insteaf of CString with an edit control?

Thanks in advance.

you can write a new DDX function to grab the text from the edit control into a std::string. look in dlgdata.cpp (part of the MFC source) and see how the standard DDX function work. it should be pretty easy to write one that takes a std::string.
