This should be done in the OnEraseBkgnd() handler.
In your view class .h file add:
afx_msg BOOL OnEraseBkgnd(CDC* pDC);
In your view class .cpp file add:
ON_WM_ERASEBKGND()
Then you can add this function:
BOOL CYourFormView::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}

send TB_SETBUTTONINFO with sendmessage...
TBBUTTONINFO.fsState = TBSTATE_INDETERMINATE;
Don't try it, just do it! 
|
|
|
|
|
and how do i send that to send message and how do i tell it wich buttons to disbale/enable?
|
|
|
|
|
thats how its done if you tool bar control is a member of your dlg class
m_Tool.SetButtonStyle(1, TBBS_DISABLED);
m_Tool.SetButtonStyle(1, TBSTATE_ENABLED);

1) If you have a mapped variable for the dialog item:
1A) If it is a static item created with the visual editor:
itemmappedvariable.EnableWindow(BOOL);
1B) If it is a dynamic item created on the fly:
itemmappedvariable->EnableWindow(BOOL);
where BOOL is TRUE or FALSE. Setting to FALSE makes the item greyed out and not selectable by the user, which is what most people mean by disabled.
2) If you want the dialog item to completely disapear, you use:
2A) itemmappedvariable.ShowWindow(var);
2B) itemmappedvariable->ShowWindow(var);
where var=SW_SHOW to make it visible
var=SW_HIDE to make it disapear.
If you don't know what a mapped variable is, either:
1) Ggo to the item in the dialog editor. Click on the dialog item, Right click, select create variable. Fill in the name, hit OK. This makes all the coding changes so that you can use the A syntax above. If you search your dialog .h and .cpp you can see the simple changes and do others by hand. Pay attention to the lack of trailing semicolons if you do.
2) You can also use GetDlgItem(IDC_WHATEVER)->EnableWindow(BOOL) or GetDlgItem(IDC_whatever)->ShowWindow(var). Less efficient this way if you do it a lot.
Good luck!

Hiya I need to send a simple string through the com port from one pc to the other. I connected both of them together.
I have seen CreateFile to open the com port but can't get it to work for me properly.
Can someone give me simple code to show me how to make one computer listen and the other send the data..
Thanks,

Can anyone suggest a way to update an Edit box at run time while in a loop. I've tried using a declared CString variable and updatedata as well as directly updating the control with SetDlgItemText, but neither one update in real time, until the loop finishes execution.
Thanks

Painting is a deferred operation in Windows; WM_PAINT messages are only generated for your windows when the message queue is otherwise idle.
To force a repaint of a window immediately, call UpdateWindow.

Have you tried creating a thread, and passing the address of your variable control to it? If the contents of your edit box need to be changed as a result of something in your loop, you might be able to use CSemaphores to lock the thread until it needs to update the control, and unlock it from your loop. Just a thought, good luck.

After a few hours of frustrated searching, I have YET to discover whether or not or where Windows stores it's most recent boot time!! I am assuming it must be stored SOMEWHERE in the registry, but I haven't been able to find it thus far. Anyone know where I could find this information, assuming it exists?
|
|
|
|
|
GetTickCount() / 1000 = seconds since system boot
Don't try it, just do it!
|
|
|
|
|
Great suggestion!! Thanks a lot.
|
|
|
|
|
From the documentation for GetTickCount:
To obtain the time elapsed since the computer was started, retrieve the System Up Time counter in the performance data in the registry key HKEY_PERFORMANCE_DATA. The value returned is an 8-byte value. For more information, see Performance Monitoring[^].
|
|
|
|
|
HKEY_PERFORMANCE_DATA does only exist under windows Nt/2k/xp and this way is much more complicated!
Don't try it, just do it!
|
|
|
|
|
Yes, but it doesn't wrap around after 49 days.
|
|
|
|
|
Thanks, I've seen some of the documentation for Performance Monitoring, but true to Microsoft form, there isn't a simple way to do what I want that is OBVIOUS to find (hello, MS documentors, you reading this? Probably not....)
Between the two suggestions, I've got enough to work on.
Thanks.

I have been trying to create the world's simplest ODBC database application accessing to an Oracle database. I am using VC++.Net. The problem occurred when I clicked at the Finish button. Options selected: SDI, Database view without file support, no compound document support. And at Database Support, I leave bind all columns checked.
Here is the error message:
Microsoft Development Environment
Error occurred while converting the wizard's text to the code page of the existing text in the file: C:\Excercise\db4\db4Set.h
Please help. I can not go any further until this is resolved.

1 point for repeating a post!
Don't try it, just do it!

I have been waiting for someone to respond. It seems to be a common problem that I can not even create a simple application from the wizard.

"code page of the existing text "
Not sure of this. But is it the language setting problem? I see this code page setting in *.rc. When having the VC 6.0 project to be run on different language version OS. This problem oftenly occurs. The VC IDE will automatically convert your project setting to different language pack based on your OS.
Hope this helps.

I have Windows XP. The application I was trying to create was a brand new simple MFC ODBC application using VC++.NET to display some fields in an Oracle database. I accepted all the default from the wizard.
You mentioned about Languge setting. Before a project is even built, how can I get to the Language setting page?
