Version number in comment

2-Jun-04 7:30

Its sounds as though the Search button is not the default button. Does the property sheet have an OK button?

Does anyone know if there's a relatively easy way of inserting the VERSIONINFO data into a C++ comment. I want to annotate my changes with the current build number. Any ideas?

Many thanks,

Do you mean at compile time or run time?

I actually mean at edit time. What I really want is a Visual Studio add-in or macro that inserts a comment like:

.... // Modified R A Pickford [02-Jun-2004 Build 2108]

Doesn't have to be exactly that format but it's getting the build number in that is foxing me at the moment. I may have to write my own addin.

Isn't that number determined by you?

Yes and no. I use VERSIONINFO and increment the Build number on every major release build so I wanted to automatically put that number into my comments. Confused | :confused:

Modeless Dialogs Overlapping Formviews

Use a version control package. Then consult the documentation for that package. In CVS you can use

/* $log$
*
*/

to place your change comments in the code, but if you don't use CVS that isn't helpful. There are other things too that you can add, some of which are suitable for assigning to a variable so you can manipulate the version in code.

When using both modeless dialogs and formviews together in an application, is it an inherent nature of the modeless dialog to always overlap the formview? I know that a possible solution is to pass GetDesktopWindow() as the second parameter in the Create() function for dialogs, but that is not desirable for what I am doing. I want the application's mainframe window to be the parent window. However, when I use this in the Create function, the dialog still covers the formview. Is there any way to prevent my modeless dialogs from hiding my formviews?

Thanks for any suggestions.

I have problem with an executable with a MFC dialog. Whenever my dialog is up and i switch to MS Word or Paint then close down Word or Paint my exe locks up. It does not seem to repaint or return control when word or paint is shut down.

any suggestions?

Are you doing anything within OnPaint, KillFocus or SetFocus that could be looping?

I suggest that you:

1) run your application in debug through the IDE.
2) Switch between programs.
3) When you switch back, use the IDE to break into your program.

You should have a better understanding of where it is and what it is doing then.

No WM_NOTIFY messages

Accessing a remote computer from inside a service

My dialog(modal) does not get WM_NOTIFY messages.

How can it be fixed?

Thanks.

Hello everyone,

I am updating the code of an already working service. I am trying to start a service on a remote computer from within the main function of the initial service. First I check if the executable of the service is in place and the check fails even if it is there. When I remove this check and try to start it anyway I cannot access the Service Control Manager with the following command:

scmHandle = ::OpenSCManager(serviceComputer, 0, SC_MANAGER_ALL_ACCESS);

It works locally, let's just say for simplicity that I specify as service executable:

\\mypc\c\temp\bla.exe

Is it possible what I am trying to do (by changing permissions in the creation of the initial service or something), or should I forget the whole thing?

Thanks a million in advance

TTN_NEEDTEXT never called

I have a CDialog.
I'm trying to implement tooltips for the edit controls of the dialog.

I adde the code :
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXT,0,0xFFFF,OnToolTipNotify)
in the message map

and my function is :

BOOL CPageCurrentLoop::OnToolTipNotify( UINT id, NMHDR * pNMHDR, LRESULT * pResult )

The problem is the OnToolTipNotify never gets called. Even if the mouse pointer is over CEdit controls of the dialog.

Thanks.

Has EnableToolTips() been called? You might need to use:

ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipNotify)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipNotify)

Also make sure that no other control (e.g., group box) is obscuring the CEdit controls.

I tried this and it does not help.
I noticed that I dont get any wm_notify messages.

I guess they are "kidnapped" somewhere along the way.. but where?

Meaning that EnableToolTips() has been called and both entries are in the dialog's message map? How are you verifying that OnToolTipNotify() is not getting called?

Yes, EnableToolTips() has been called and both entries are in the dialog's message map.

I tried putting a break point in the message handler in debug mode and never got to the break point.

Then I tried with the spy++ to find out if any notify message is sent and non are sent.

I have complex structure here that might be the reason:

I have a dialog box with a tab control. The tab control has a few pages which are all implemented as child dialogs of the tab control.

I'm trying to add tool tips to some of the controls of the tab pages dialogs.

Thanks.

Did you call EnableToolTips from within your dialog window?

Modeless dialog

hi all

i have a modeless dialog which i call, kind of a waiting dialog if you like

i use

CCPServerWait* m_pWaitDlg;
m_pWaitDlg = new CCPServerWait;
m_pWaitDlg->Create(IDD_DCPSERVER_WAIT
m_pWaitDlg->m_wait_mes = "ConfimingDetails...Please Wait";
m_pWaitDlg->UpdateData(FALSE);
m_pWaitDlg->CenterWindow(CWnd::GetDesktopWindow());
m_pWaitDlg->ShowWindow(SW_SHOW);
m_pWaitDlg->UpdateWindow();

however im getting a debug assertion error on wincore.cpp when i run my program

when i look at the value CCPServerWait has when i step through hWnd is equalling nothing

CCPServerWait {CCPServerWait hWnd=???} CCPServerWait

this used to work fine until i added in the line of code below before the
dialog is called

ok = SQLCreateDataSource(m_hWnd,"CP_CMIS_CON");

which allows the user to create a Datasource
if i take this out the above works, but with it in
it throws me out an error on the m_pWaitDlg->UpdateData(FALSE); line

i assume this is because hWnd=???

but i dont know how to fix it

any ideas ???? Confused | :confused:

You're calling UpdateData() but the controls do not exist yet. Remove that call altogether. Then in the dialog's OnInitDialog() method, use SetWindowText() instead. The CenterWindow() call should be moved to the dialog's OnInitDialog() method.
