What value does nResponse have? That would seem to be the simplest and most basic thing to check...

edit : a fraction too slow Smile | :)

In which case, you must be doing something very naughty in the dialog...

You need to step through the code in there, and see where it's going wrong. Put breakpoints in all the event handlers, and track through until you find the place it crashes.

I just created a new project and using the default setting...

I still don't get the nresponse..

BOOL CToolApp::InitInstance()
CToolDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
//  dismissed with OK
MessageBox(NULL,"It Works Now","Information",MB_OK);
}
else if (nResponse == IDCANCEL)
{
	// TODO: Place code here to handle when the dialog is
	//  dismissed with Cancel
}
{

I left the CToolDlg as default..I din't put any code and just clicked the ok button.
I don't get a response back.

Sounds like there's something wrong with your system, then - I just tried the very same thing and it returned 1 (IDOK) as expected when I pressed the OK button.

Single-step through the MFC source code of the CDialog::DoModal call. That should let you see what happens in and after the modal message loop.

I did single step...I do see nResponse comming back as 1. However it's just jumping the whole if block and going straight to return FALSE.

This is with just plain project no code anywhere except a message box inside the

if (nResponse == IDOK)
{
MessageBox();
}
else if (nResponse == IDCANCEL)
{
}
It's jumping this whole block.

it going to return FALSE;

the follwing is what I get at the end of the steping through.

'Tool.exe': Loaded 'C:\WINDOWS\system32\imm32.dll'
'Tool.exe': Loaded 'C:\WINDOWS\system32\uxtheme.dll'

However I did an uninstall of the update of Internet Explorer that was done on this machine a week ago.

I am Running Visual Studio 2008
Version 9.0.30729.1 SP

Not sure if the above info makes any difference?

I'm surprised that it doesn't execute the messagebox - VC++ will (even in Debug mode) optimise away a completely empty if...else... statement

Well is there a way I can work around it?, I guess reinstalling is not going to help either?

Quick question are you running the same version of Visual studio 2008?

Could you let me know what version you running?

I could uninstall 2008 and revert back to 2005 if I have to?

Thanks a million.

I don't there's a problem with your installation from what you've written - what you've said indicates that the right thing's being returned. Why doesn't that translate back into your code? Not sure.

By debugging your code and working out why your code's not getting called when it should be. If that means debugging assembly language, then that's what you need to do.

I am not sure what to say, I just installed VS on a different machine and I get the same thing, no message box.
I used a full install.

Which says there's something not quite right with your code, not your Visual Studio install.

Debugging's the way forward in this case, I'm afraid.

Hello there,
Found it.
This should have not been used, when I am verifying the key to the main app.

m_pMainWnd = &dlg;

Thanks a lot for all your help.

You should check the return value of SmsSendMessage.
This will give you a better idea.
Look at the documentation of SmsSendMessage[^] in the Return Values section.

Power configuration settings on Win2K3 and Win2K using "powercfg.exe"

sandy.pune4-Jul-09 1:29

4-Jul-09 1:29

I am using the "Powercfg.exe" (Power Settings Command-Line Tool) for changing the power settings on different platforms.
The power options (switches) I am using are
1. Enable Hibernation (/HIBERNATION)
2. Enable Device wake (/DEVICEENABLEWAKE)

For Windows XP and Vista these switches work perfectly fine.

The problems I am facing are on Win2K3 and Win2K
1. Win2k3: "Powercfg.exe" do not have the “/DEVICEENABLEWAKE" switch. Is there any another way to configure the device wake enable settings on Win2k3?

2. Win2K: do not have the "Powercfg.exe" command line tool, if we are using the Win2K3 "Powercfg.exe" utility to change the settings. The same issues are there for Win2K as well.

Apart from the command line configurations are there direct APIs available?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
