Be glad I'm not a user of that program: I'd vote for more torture than the MS Explorer team should have (because they didn't do their stuff conciously malicious that you apparently do).

Now Virus writers are going to force users to write a password to get OUT of their programs?!

Why can't you just SEGV like every nice MS program?!

OK. A serious answer here would then be: replace Explorer.exe with your program. Seriously!

If you _only_ want your program to run on that machine, replace the shell with whatever you like.

But wouldn't that be wasting money for your customers, using full Windows installations as just the back-end for your program?

I have it sorted now, I just trap the WM_CLOSE message, and direct the user to my exit screen, its manly intended to stop the user accidentally closing the program, as they are generally not PC aware, and it would mean a call to the site engineer at 4:00am to go to site to get the system working again because we all know its always the early morning shift (that are bored) that cause these sort of problems and as the system is very expensive 1/4 mill Its a Big Machine the cost of NT4.00 is small, we usually use the policy editor to restrict access.

There's a good chance these tips are loaded from resources. In the toolbar's parent window, you can handle TBN_GETINFOTIP to eliminate the default behavior.

hi i have this code that should take the data in "m_copyed" and increment it by the value in "keyvalue".
But i seems to only increment the data by '1' and ignoring the value in "keyvalue"

radio_select=3;
for(int i=m_copyed.GetLength();i--;)m_copyed.SetAt(i,m_copyed[i]+ keyvalue);
SetDlgItemText(IDC_CHANGEDDATA, m_copyed);

i have some extra code in another area of the program shown below code this be the problem>

GetDlgItemText(IDC_EDITDATA, m_typing);
m_copyed=m_typing;

NOTE - i have 2 edit boxs "m_copyed" and "m_typing", i'm taking the text from "m_typing" incrementing it by the value in "keyvalue" and then displaying it in "m_copyed"

any help would be appreciatted

ive just declared it as an 'int'

not sure where else i should set the value

thanks for the help

Re: help needed

29-Apr-02 2:51

But to what value and where ? What are you trying to achieve ?

Re: help needed

29-Apr-02 3:05

i havent set it at any value.

when the program is ran, the user enters a value which is stored as "keyvalue".
This value say '2' is used to move the text in "m_typed" by 2 positions. So if the word was 'SUMMER' it would become 'UWOOGT'

You're converting the value typed in to a number, right ? Or you're calling UpdateData() before using the value if you've set it to be an int in the Class Wizard ?

I just wanted to verify this is what you wanted to do. I reckon you're forgetting to call UpdateData before using the variable.

Windows Script Host

29-Apr-02 1:42

Hi,

I am working on making my app a Windows Script Host. So far I have a class that entirely works. You might say why do I need help?

Well, here's the thing. I can add an automation object to the engine so that I can have my own methods. But if I don't name the object in ParseScriptText (2nd parameter), it never finds the 'new' functions when I run the script.

Therefore, I can make it work when there is one object (by naming it in ParseScriptText), but not if I have 2 or more since there is only one param.

Do I have to call ParseScriptText in a loop for all added name objects to get more than one object to work with the engine?

Thanks in advance,

Simon

I think you need to look into using AddNamedItem which is part of IActiveScript.

My code uses something like

void CLittleScript::ParseScript(LPCTSTR sScript)
{
    EXCEPINFO ei;
    _bstr_t bstrParseText(sScript);

    HRESULT hr = m_iScriptParse->ParseScriptText(bstrParseText.copy(),  
                 NULL /*L"MyApp"*/, NULL,NULL,0,0,SCRIPTTEXT_ISVISIBLE, NULL, 
                 &ei);

  if(hr == S_OK)
  {
    hr = m_iScript->SetScriptState(SCRIPTSTATE_CONNECTED);
  }
  else
  {
    littleDebugger()->Error("Failed to Parse Script Text %x", hr);
  }
}

HRESULT CLittleScript::AddScriptObject(LPCSTR sObjectName, IUnknown* pObject)
{
  m_ScriptSite.AddScriptObject(sObjectName, pObject);
  HRESULT hr = m_iScript->AddNamedItem(_bstr_t(sObjectName),
  SCRIPTITEM_ISVISIBLE | SCRIPTITEM_ISSOURCE);

  if(hr != S_OK)
  {
    littleDebugger()->Error("Failed to add named item %x", hr);
  }

  return hr;
}

In my ActiveScriptSite::GetItemInfo, I loop through for the required object interface.

if(dwReturnMask & SCRIPTINFO_IUNKNOWN)
{
  for(int nLoop = 0; nLoop < m_collectionObjects.Count(); nLoop++)
  {
    SCRIPTOBJECT* pObject = m_collectionObjects.GetItem(nLoop);
    if(pObject)
    {
	_bstr_t a(pObject->m_sName.c_str());

	if(!_wcsicmp((const wchar_t*)a, pstrName)) 
	{
      	  (*ppunkItem) = pObject->m_pObject;
	  pObject->m_pObject->AddRef();
	  break;
	}
    }
  }
}

Silly MFC CString Question

carrie29-Apr-02 1:42

29-Apr-02 1:42

Hi, I'm still a bit new to MFC and I'm having a really silly problem with it.

I'm trying to make a dialog based program that will allow someone to pick a text file, the program loads it up and then there will be a list of things. No probs on getting to pick the txt file but what I need is for the program to be able to notice duplicate entries in the txt file and then pick one of them out, ignoring the rest of the duplicates.

Also, even sillier, I need to make something that displays a bunch of strings that contain text in them. I'm having the problem though that some of the strings that I need it to show contain things like

ReplyHello=/ :-: \
ReplyHelp=Help?

whenever I try to do a
CString m_something=(_T("ReplyHello=/ :-: \\nReplyHelp=Help?"));
I get errors about teh escape codes.

Any help for a lost soul? Thanks

Easy - let STL do the dirty work for you. If you store the information in an STL set, it will discard duplicates as you go. I've written an article on this, just search for 'graus map set' to find it. You can also read a text file into an STL container in just three lines of code - I show that in my STL articles as well.

I don't see anything wrong with the string you're setting, but if you're getting an escape code erro,r chances are you tried to insert a \, and forgot to put two of them, as \\ is the code for \, as \ denotes the begining of an escape code, such as \n for newline, or \r for return.

Don't feel silly, you should see some of the stuff I asked when I was starting. We all start somewhere.

ToolTip Problem

I'm trying to display ToolTips on one of my dialogs using

ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNotification)

It only works for some of the controls. I've used Spy++, and the non-working controls just aren't firing the WM_NOTIFY message. Anyone know what to do about this?

(I have a couple of frames on the dialog - will that mess things up?)

When I create a "MFC EXE" project with "Dialog Based" application I have at the begining 2 classes in it: Application class and Window class. When I add menu to the window and write message handler (for example OnExit) for menu item click, my window class disappears from the project! Confused | :confused:

The source code files for that class are still in the project, but no class Frown | :(

After few seconds the application class follows the window class Mad | :mad:

Is that a bug for Visual C++ 6 IDE? How can I solve that problem?
Thank you.
