Are you honestly saying that 2005 EE ONLY lets you use managed C++ ? Do you realise the difference between this and C++ ?

You're wrong, you can build C++ applications with EE 2005, you don't need to use managed extensions. I just checked the Microsoft site.

If you're learning, you should learn C++ first, then MC++. This way, you're essentially learning two languages at once. MC++ is C++ with additional constructs that let you use the .NET framework ( which means your app requires the .NET framework 2.0 to run ). You should write some console apps first, then some MFC apps before moving to MC++, and if you still want to, you should learn C# instead. I don't see any reason to use MC++ except to write bridging dlls between C++ SDKs and C#.

*edit* actually I don't think the free version offers MFC or ATL. Which means you're stuck with MC++ or Win32 SDK style code for windows apps, I guess.

I agree with all that Christian has said about the design being inappropriate but that's up to you.

The simple answer to the problem you have is that your timer event handler cmd_time_reached is not a member of the frm_splash_screen class so this->Close() will not close the splash screen (this doesn't point to it).

You don't show how the splash screen is created but you could keep a handle to it and do SplashScreen->Close()

Looking to extract text from a Word Doc

I am looking to develop a simple app in C that will search and extract text from a MS Word document and was hoping someone might be able to share their code or point me to a good source I can model. Thanks. Confused | :confused:

Need SOAP Information

17-Aug-05 10:53

I am trying to write an app in VC++ (2002, 7.0) that reads information from a remote SOAP server. I've been trying to find something usable on here and on web searches but I can only find .NET or C# examples or irrelevant C++ examples. I'm looking for a piece of simple SOAP client source code in VC++ to send a request and receive a response. Can anyone point me to a good simple example I can work with?

You don't want to use the APIs that do this automatically ? I'm sur ethere's an SDK for this sort of thing.

Well, I went to this microsoft.com site for the SOAP Toolkit 3.0 which is the SOAP SDK but the first thing it says below the file information is "The Microsoft SOAP Toolkit is deprecated by the .NET Framework." and also later it says that the active toolkit support has expired so no new work will be contributed to it by Microsoft.

Christian Graus17-Aug-05 12:14

17-Aug-05 12:14

Which just means they want you to use the .NET framework for SOAP. If you're not using Managed C++, then you can't do that, so..... You're still better off with a toolkit that exists than writing from scratch, surely ?

How to update CListCtrl when item is inserted

Hello,

I'm inserting hundreds of items into a CListCtrl. Currently, the CListCtrl is only being updated after all of the items have been inserted. I want the CListCtrl to be updated as each item is added (that way the user has immediate feedback rather than having to wait several seconds for something to happen).

I'm currently working in code that is not mine (and not commented) so it's difficult to tell if this is typical behavior or something the previous programmer introduced.

I've tried invalidating the client area after each item is inserted but this doesn't fix the problem (shouldn't this send a WM_PAINT message and force the client to be redrawn?)

I'd really appreciate any help anyone could give me.

Thanks!

don't do that, it will slow your application.

and the user will not be able to do anything while the list is populated; assuming you are doing something like :

while ( something )
{
  insertItemInList( someItem );
}

have a look a this article ( http://www.codeproject.com/listctrl/virtuallist.asp[^]
) it shows a technique to improve performance for lists with a large number of items.

I'd suggest looking for calls to SetRedraw(FALSE) and SetRedraw(TRUE) placed at the start and end of the loading process.

That was it! There was a call to SetRedraw(FALSE) buried four calls down on the stack.

Hi,
I am doing a project in win32 vc++. I display some text in edit control. I read the text from file into a string and set it to the edit control...
by
SendDlgItemMessage( hDg,IDC_HELP_TEXT, EM_FMTLINES, TRUE,0 );
SetWindowText(GetDlgItem(hDg,IDC_HELP_TEXT),(LPCSTR) Helptext);

But when I run the project all the text displayed in the edit are highlighted i.e. selected. How do I overcome this.
Thanks in advance.

Send the control a EM_SETSEL message (after the dialog has been fully initialized).

You have to do this after the dialog has finished initializing. One of the last things that happens to a dialog during initialization is to set focus to the first non-static control, and if that is an edit control, all of its text is selected. Unselecting text before then is pointless.

case WM_INITDIALOG:
    ...
    SetWindowText(GetDlgItem(hDg,IDC_HELP_TEXT),(LPCSTR) Helptext);
    PostMessage(hDg, PM_DESELECT, 0, 0); // last thing to do
    break;
case PM_DESELECT:
    SendDlgItemMessage( hDg,IDC_HELP_TEXT, EM_SETSEL,-1,0 );
    break;
