How to resolve Error:2039

Hello,
Using MIB_IPADDRTABLE structure, you can retrieve IP addresses associated with every networks adapters. But what about retrieving a description of those network adapters (Bluetooth, Wi-fi, Ethernet...) Which function to use?

Thanks,

Thanks for replying.
But in order to use ShellExec or CreateProcess, I need to know where to find the Winamp executable installed on the user's computer. How can I find this path?

Thanks,
Allad

The first thing to look for is does the exe support OLE automation - If it does you should use COM to launch it. I'm no WinAmp expert but after looking in the registry of my computer I knocked up the following program which launched WinAmp:

// WinAmp.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
#include <objbase.h>
 
static const CLSID CLSID_WinAmp = 
{ 0x46986115, 0x84D6, 0x459c, { 0x8F, 0x95, 0x52, 0xDD, 0x65, 0x3E, 0x53, 0x2E } };
 
int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
	CoInitialize(NULL);
 
	IUnknown *pUnk;
	if ( SUCCEEDED(CoCreateInstance(CLSID_WinAmp, NULL, CLSCTX_ALL, IID_IUnknown, reinterpret_cast<void**>(&pUnk))) )
	{
		pUnk->Release();
	}
 
	CoUninitialize();
 
	return 0;
}

NOTES:
I hardcoded the CLSID which I got from the registry - There is probably an SDK that can be used. This would also contain interfaces which would enable to control the instance of WinAmp launched.

Thanks for your reply.
However, I've never done OLE programming before. Is the CLSID the same for every computer running Winamp?

Thanks

Can not add new controls to class?

Stephen Hewitt31-Mar-06 17:36

In general that's the idea - But I hacked this CLSID out of the registry; It wasn't sourced from any official documentation.

I have a CDialog based class and I put a CListCTrl on it then did the cTRL-W thing (VC6) to make a new class out of it. Now I realize I want more controls on it. IF I just draw them on, I dont get any thing mentioned in the class cpp file (I even rebuilt). So is it a fact that you have to have your design completely done before you make a class out of it?

No, not at all. You can open ClassWizard as many, or as few, times as you want.

Can't find clipboard is busy error

30-Mar-06 10:56

The C in DC stands for context, which infers that it is only meaningful in a specific context for a specific device. Sending that to another computer makes no sense. You can, however, send the screen data in chunks to the other computer. The Terminal Services API might be required, but I really don't know for sure.

This is partly the problem, no clear repro on it. When it happens it's frequent but not consistent. Most of the time it's the main app window becoming the active window.

So do you have code someplace that it interacting with the clipboard?

OnInitialUpdate() never gets entered

Harrier30-Mar-06 10:44

Harrier

30-Mar-06 10:44

Probably. Not my code. Inherited. I try to find a repro before digging through code. I've googled all sorts of keywords and only found one non-english site with the same error message. Now here I am hoping someone who actually has written code for the clipboard knows what this means. I could try looking through code but I don't know what I'm looking for.

Here's the code I added to my CDialog

// Overrides
	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CTargetInfo)
	public:
	virtual void OnInitialUpdate(); // called first time after construct

and

void CTargetInfo::OnInitialUpdate() 
{


	if(NULL != m_listTgtInfo.GetSafeHwnd())
	{
		(void)m_listTgtInfo.SetExtendedStyle( LVS_EX_FULLROWSELECT );
		m_listTgtInfo.InsertColumn(0,"Keywords",LVCFMT_LEFT,800);
		//m_keysListBox.SetColumnWidth(0, LVSCW_AUTOSIZE_USEHEADER);

		m_listTgtInfo.SetExtendedStyle(LVS_EX_CHECKBOXES);
		m_listTgtInfo.InsertColumn(1,"Options",LVCFMT_LEFT,800);
	}

}

It nevers enters the OnInitialUpdate

The way I am creating the dialog is

                   m_tgtInfo = new CTargetInfo(this);
if(!m_tgtInfo) return CDialog::OnCommand(wp, lp);
m_tgtInfo->Create(IDD_DLGTGTINFO, (CWnd*)this);
m_tgtInfo->ShowWindow(SW_SHOW);

Is there something else I need to do?
thanks,
sb

OnInitialUpdate() is for a view, not a dialog. Override OnInitDialog() instead.

Why not create a modal dialog instead:

CTargetInfo dlg;
dlg.DoModal();

Thanks, David.
It needs to be modeless. Now that I made it OnINitDialog, it does go into the function but sidesteps my if safeHWnd block for the list control on that dialog:

if(NULL != m_listTgtInfo.GetSafeHwnd())
{
    (void)m_listTgtInfo.SetExtendedStyle( LVS_EX_FULLROWSELECT );
    m_listTgtInfo.InsertColumn(0,"Keywords",LVCFMT_LEFT,800);
    //m_keysListBox.SetColumnWidth(0, LVSCW_AUTOSIZE_USEHEADER);

    m_listTgtInfo.SetExtendedStyle(LVS_EX_CHECKBOXES);
    m_listTgtInfo.InsertColumn(1,"Options",LVCFMT_LEFT,800);
}

I thought my CListCtrl would have been made by the time the code gets to the OnINitDialog. So if I cant set the columns of the listbox in this function, where else can I set them?
thanks,
sb

The controls have been created, assuming you have bothered to call CDialog::OnInitDialog() first.
