And you're wondering why? Perhaps it's because there's a compiler error (hint: messageToWrite is never declared).

I suppose that wasn't the problem. My CPMRU says he just omitted the declaration in the OP and was in fact making a UNICODE build. Roll eyes | :rolleyes:

Hi all,
Is there any method to hooking/getting notified the common error message dialogs ("Application error", "Microsoft Visual C++ Runtime Library", Window error reporting dialog etc) from any applications.

Thanx in advance

You can create a CBT Hook or a Shell Hook to be notified whenever a new dialog box is going to be created. You can then check its caption and text.

Check this[^] out, or 0this[^], or for a more generic aproach look at this[^], but most importantly, google is your friend, you just have to know what to look for.

not enough information.

Things you may need to consider :-

Are the two exe's on the same machine ?
How much data is to be exchanged ?
Do you need a proprietary protocol ?
.. and probably a million other questions

If the two exes are not on the same machine, you might need tcp/ip messaging for example, it could be low level if you have your own protocol in mind or MSMQ for example. If the are on the same machine, you need to read up on 'IPC' - which could still be sockets, or shared memory, windows messages for example

I'd suggest you refine your requirements, then use google to look around - there's plenty of code out there to help you.

Dynamically changing a dialog template

Hi all,
I wish to choose a dialog template resource dynamically.
The problem is that i wish to do it for the application main dialog, so its a modal dialog and i
cant choose it in a Create function. Unsure | :~

Thanks

Check out CDialog's constructors, they look something like this:

CDialog::CDialog(LPCTSTR lpszTemplateName, CWnd* pParentWnd)
{
	...
	m_lpszTemplateName = lpszTemplateName;
	if (IS_INTRESOURCE(m_lpszTemplateName))
		m_nIDHelp = LOWORD((DWORD_PTR)m_lpszTemplateName);
	...
}

CDialog::CDialog(UINT nIDTemplate, CWnd* pParentWnd)
{
	...
	m_lpszTemplateName = MAKEINTRESOURCE(nIDTemplate);
	m_nIDHelp = nIDTemplate;
        ...
}

So probably all you have to do is change m_lpszTemplateName and maybe m_nIDHelp before calling DoModal to the apropriate value, so something like:

INT_PTR CMyDialog::DoModalWithID(UINT nIDTemplate)
{
	m_lpszTemplateName = MAKEINTRESOURCE(nIDTemplate);
	m_nIDHelp = nIDTemplate;
	return DoModal();
}

Does this work for you?

I just tested it, it works for me. Maybe there are "version based differences" that cause the trouble, i did the test on VC++ 2003, version 7.1.something, show your code and maybe we will see what might be the problem.

You were right your suggestion indeed changed the resource, the visualization of
the dialog was dependent on another factor. Poke tongue | ;-P

Missing Dll for executable package of Visual Stdio 2008

I have built an executable package in release mode in VC++.Net 2008(MFC). The package is running in my PC well but in other PC that doesn't have Visual stdio, is showing dll(mfc90.dll, msvc90.dll etc ) missing.

If I install Visual stdio 2008 redistribution package then it is working. Is there any way to run my package without installing Visual stdio 2008 redistribution package? How can I do this?
