Thanks for the hint. I think its fine, since its returning nonzero values (is a digit).

Appreciate your help,

Here ya go.

bool isDigitString (CString strDigits)
{
  long nValue;
  bool bIsDigits = (sscanf (strDigits.GetBuffer(0). "%d", &nValue) == 1);
  strDigits.ReleaseBuffer();
  return (bIsDigits);
}

I am rapidly accumulating a word doc of the snippets i get off CP...handy. Say hello to your mom from me too...BTW I consume mass quantities of Jello (or not so much)....

I have a peculiar system mmenu crash I posted about if you want to check it out (of course you dont have to Smile | :)

).
We get 59 minutes off work tomorrow - yay, but I might have to go help set up some dumb food event at the base here. I got stuck with collecting donations etc. Ugh!

Will do!

Hmm, need more info. As Tomasz said, can you pinpoint where your app dies? Also, is it an ASSERT failure or something else?

Anyone know anything about Forking Emails from within a SMTP Transport Event Sink ?

Thanks,

How to pass in an LPTSTR to SetItemText of listctrl

ns3-Oct-02 3:02

3-Oct-02 3:02

I have:
( Iforgot how to format the less than sign for CP...)

  CString * p;

  p = new CString [iArraySize];


 for (int i=0;i less than iArraySize;i++)
{
   p [i] = pArray[i];

}


  int nIndex = InsertItem(LVIF_TEXT|LVIF_STATE, nPos, p[0],0,LVIS_SELECTED,0,0);
  ASSERT(nIndex != -1);
  if (nIndex < 0) return(nIndex);
  for ( i = 1; i (less than) iArraySize; i++) {

          SetItemText(nIndex, i, p[i]);   ///crashes here.
      }

From MSDN,

BOOL SetItemText( int nItem, int nSubItem, LPTSTR lpszText );

So I think its my third argument thats a problem. How do I fix it so that the two are reconciled?
Thank you and

I tried passing in the .GetBuffer of the CString, but that didnt work either:

for ( i = 1; i < iArraySize; i++) {

        SetItemText(nIndex, i, p[i].GetBuffer(p[i].GetLength()));
    }

LPTSTR is a typo in MSDN. The actual code uses LPCTSTR, which is just const char * in non-unicode build. You can safely pass CString by value to CListCtrl::SetItemText, your crash is related to something else - I guess you've screwed something with pArray.

Many thanks for the response. Just wanted to say that yesterdays CListCtrl multislect problem you helped me with is on its way pretty much. I used GetFirstSelectedItem etc, and have SetCheck working for a multiple select. DOnt have the logic for uncheck if clicking on a selected item figured out yet...the TRACE really helped me see that the itemchanged fired multiple times...

Is there any way to enumerate the current windows hooks set on the system or is there any way to detect spyware like software ? Does anyone ever worked on a software like this ?

Hi!

I need to catch messages from other applications in my own program
(something like spy++).
When I get the application, but how do I process its messages?
Do you know where I can find an example?

Thanks

Dialog Box after Dialog Box

Dear All,

I'm trying to make a program that looks like installer programmes that displays one dialog box at a time. The user will then just have to chose some options and click Next to the next dialog box. Problem is I do not know where to start and how to structure the program.

Can anyone please help me out here.

Many many thanks in advance

Chun Te, Ewe

Property pages might be your best bet - then you can keep the same main window open, and just switch between pages when the user clicks the next button

Hi
So you want to do a wizard: dialog with Next, Prev and Finish button.
All you have to do is to use two classes: CPropertySheet and CPropertyPage. CPropertySheet will be used as a kind of container for the dialogs through which user will be able to iterate. In CPropertySheet look at the functions: SetWizardMode and SetWizardButtons. Add to you program one class that inherites from CPropertySheet and as many as you need classes that inherites from CPropertyPage(one class for every page in wizard). You can find comprehensive explanation in MSDN (start with classes CPropertySheet and CPropertyPage, that should be enoguh).

Greetings

I've just done a similar thing myself. It's easy enough to switch between a normal Property Sheet/Page implementation to a wizard look-and-feel by use of the CPropertySheet.SetWizardMode call before the sheet is invoked, as described in the previous post.

A few things that tripped me up when I was first doing it:

1) the title in a wizard is actually driven from the tab text you would normally see for the property page being displayed, NOT from the property sheet title.

2) The buttons displayed/enabled/disabled need setting from the PropertySheet, not the Page, so although the page is the one that needs to initiate the button display, it is actually the sheet that needs to do it.

3) If you go for the wiz98 type styles (nice bitmap backgrounds) then they change format between mfc6+7!

Err..of course I meant wizard97 styles.

I do have a very simple test project I created in VC++ 6.0 that illustrates how to do this. If you're interested, then email me.

As an aside, I could put this in the archives section, if it would be useful to anyone else, but it is *very* simple, so there might well already be one there already? What are the guidelines behind putting articles in?
