what do you mean by 'formatting?' if youre trying to get strings into a listbox, you can use

My_List_Box.AddString("hello");

if you mean turning off alphabetical sorting of the contents of the listbox, in the resource editor, witht he listbox selected, look in the properties window and set the 'Sort' value to False (or off, depending).

is that what you mean?

How you want the data formatted will govern whether you want/need to use a list box, list control, or a grid control.

Although it's possible to make a list box look like it has columns, it remains a one-column control that uses tab stops to separate the columns.

Sorry for not being clear...

I would like to have the words spaced out in the line of text. Just so that it is easier to read. I want it so that I do not have to manually hit the space bar between the words that i am gonna enter. Some of the information going on the lines are spaced further in that another like in the chart below.

Ideally I want my dialog box to look exactly like this:

           Team 1      Team 2      Team 3      Team 4
Game 1       80          69
Game 2                               79          70
Game 3       55                      73 
Game 4                   73                      82

Player #22 from Team 3 is the MVP of the tournament.  
He lead the team in points, rebounds, assists and steals.  
He also led the tournament in points (33.2), assists (8.9), and steals (3.2)

I thought about using a list control, but i couldn't get the last 3 sentences to appear across the columns.

THANKS IN ADVANCE!!!

Use an edit control with a fixed-space font.

Hi,

I am really new to programming, and do not fully understand how to do this. (The fix spaced font)
Can you possible give more details on how to do this? Will this get my "table" to look exactly how i want it?

Thanks again. Sorry for being slow with this. Mechanical Engineers are not the best programmers! Poke tongue | ;-P

Just as an example, if you had a dialog box with an edit control, you could put the following in the dialog's OnInitDialog() method:

m_font.CreateStockObject(ANSI_FIXED_FONT);<br />
m_edit.SetFont(&m_font);

Now you just format each line that is added to the edit control.

Use CListCtrl instead of CListBox. With the List Control, you can create columns. In your case, you need to create 4 columns and add the data to each column individually...

Hi,

I tried doing that, but is there a way for me to insert the 3 sentences that follow the chart and span them over the columns. I was originally using the list control, but could not find a way to do that.

Any help would be appreciated.

Thanks in advance

One solution is WaitForSingleObject().

GetExitCodeProcess() returns the process's exit code, or STILL_ACTIVE if the process is running.

As for getting 'running' or 'not responding' in the sense of the Applications tab of Task Manager (in Windows NT), I think Task Manager has some kind of hook to be able to tell this. You could try using SendMessageTimeout() to send a message to the top-level window - if it responds within the timeout, it's responding. I'd suggest using either WM_NULL or a guaranteed-unique registered message from RegisterWindowMessage() - perhaps a string representation of a GUID?

dialog menu & update_command_ui

Steve L.9-Jul-03 1:59

9-Jul-03 1:59

I've added a menu to a dialog application and am trying to grey out some parts of the menu. However, the call to my UPDATE_COMMAND_UI function is not called until after the the menu has been clicked. I'm guessing I have to do something different since it is a dialog app, but I don't know what and can't seem to find it. How can I do this?

Thanks in advanced

Hi!
This code may help you!It has everything about changing dynamically menu items:
void CExampleView::OnUpdateEditInsertolecontrol(CCmdUI* pCmdUI)
{
// TODO: Add your command update UI handler code here

// Specific for the example
pCmdUI->Enable(m_pControl == NULL);
}

void CExampleView::OnEditInsertolecontrol()
{
// TODO: Add your command handler code here
COCBrowserDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);

// Your code ...

// Change menu item (Insert OLE Object -> Delete OLE Object)
CMenu *menu;

// 'Edit' is the second submenu (index = 1)
menu = AfxGetApp()->m_pMainWnd->GetMenu()->GetSubMenu(1);
menu->ModifyMenu(ID_EDIT_INSERTOLECONTROL, MF_BYCOMMAND, ID_EDIT_DELETEOLECONTROL, "&Delete OLE Control");

}

void CExampleView::OnUpdateEditDeleteolecontrol(CCmdUI* pCmdUI)
{
// TODO: Add your command update UI handler code here

// Specific for the example
pCmdUI->Enable(m_pControl!= NULL);
}

void CExampleView::OnEditDeleteolecontrol()
{
// TODO: Add your command handler code here

// Your code ...

// Change menu item (Delete OLE Object -> Insert OLE Object )
CMenu *menu;

menu = AfxGetApp()->m_pMainWnd->GetMenu()->GetSubMenu(1);
menu->ModifyMenu(ID_EDIT_DELETEOLECONTROL, MF_BYCOMMAND, ID_EDIT_INSERTOLECONTROL, "&Insert OLE Control...");
}

GDI+ Memory leak

I am facing problem with GDI+ bitmap memory deallocation.
delete of the the bitmap doesn't release the memory it gets accumulated and it doesn't free up the memory until i close my application.

And i end up in virtual memory problem since it eats up all the memory and crashes my application.

Please suggest a scenario where in i can delete my bitmap pointers memory and run my applicaiton without any problem.

Thanks in Advance.

No. You can intercept them, so as to redirect them to your app, but you can't do anything to the message itself.

Almost. a WH_GETMESSAGE hook can modify the message, but not delete it.

A WH_MSGFILTER hook can delete messages as well as modify them.

Yes you can, by installing a WH_MSGFILTER hook, but it slows down the system quite a lot, and shouldn't be done unless necessary.

The WH_MSGFILTER hook can be either thread-specific or system-wide, but only for threads in the same process as the thread that set the hook, so it's not a true system-wide hook. To get true system-wide behaviour, use the WH_SYSMSGFILTER hook.

Are the two windows in your process or in another process? If they're in your process, a much easier solution would be to subclass the windows.

In that case, it will be much easier to subclass them and override OnActivate() and make it do nothing. It will also be a lot nicer to the system Smile | :)

Console Screen I/O

Coming from a Turbo Pascal / Turbo C++ background, I miss the good 'ole days of having complete control over a console screen using the conio.h libraries.
I have discovered that I can mimic certain functions using the platform SDK (changing colours etc), but does anyone know of where I can get some more information on using these functions more effectively? Or even if there are any (free) libraries that are compatible with VS6 that I can use.
I have tried a search on CP, but to no avail.

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