I am trying to add/modify the columns and rows of ClistCtrl, when i compile the code there are no errors but when i run the program its giving some error message 'Illeagal Operation'..
My code is as follows:
for(int c=0; c< nColumnCount; c++)
m_lc.DeleteColumn(0);
//here m_cols is the integer value entered by the user
//and m_rows is also an integer value entered by the user
//m_lc is the ListControl variable
if(m_cols > 0)
{
LV_COLUMN lvcol;
lvcol.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH | LVCF_SUBITEM;
lvcol.fmt = LVCFMT_LEFT;
lvcol.cx = 80;
CString s;
for(int c=0; c<m_cols; c++)
{
s.Format("Coloum %d",c+1);
lvcol.pszText = (LPSTR)(const char *)s;
lvcol.iSubItem = c;
m_lc.InsertColumn( c, &lvcol );
}
}
The above code i used to delete the existing columns and add new columns which is working fine
but when I tried to add the rows i am getting the error message.
The following is the code i wrote to add the row data
CString s;
for( int i = 0; i < m_rows; i++)
{
LV_ITEM lvitem;
lvitem.mask = LVIF_TEXT | LVIF_PARAM;
lvitem.lParam = 0;
lvitem.iItem = 0;
s.Format( "subitem %d", 0);
lvitem.pszText = (LPSTR)(const char *)s;
lvitem.iSubItem = 0;
int r = m_lc.InsertItem( &lvitem );
for(int c = 1; c < nColumnCount; c++)
{
s.Format( "subitem %d", c);
BOOL b = m_lc.SetItemText( 0, c, (LPTSTR)(const char *)s);
}
}
Can Any one Help me in doing the above??
Thank you.

If I add buttons while application initialization CToolBar will resize well. But if i do it in the midle of my program there is no CToolBar resizing (but buttons i can see new buttons). If I minimize and then maximiza application, then CtoolBar size will be recalculating an all OK.
Please help me. I was trying to use different pToolBarCtrl->Invalidate and pToolBarCtrl->AutoSize(), but there is no any changes.

Call the RecalcLayout() method on the parent frame.

Hi !
I'm building an ATL App with VC++ 6.0.
I added a dialog in my app with the 'Insert->New ATL Object->Miscellaneous->Dialog'.
Then, using the resources editor, I put in this new dialog a CListBox control.
Then, during the InitDialog, I try to add strings to this CListBox control using :
CListBox* pList=(CListBox*)GetDlgItem(IDC_LIST);
pList->AddString("hi");
It compiles fine, but when I run it, I get an assertion failure at the line 'AddString'.
Anyone could help me ?
Thank you !

Hi,
I tried ATLCONTROLS.H ( or whatever name), to get the sugar control classes, but I had some problems as well, have you tried, the "attach" method to attach the HWND.
I rather use, ::SendMessage stuff, when you get used to it it´s not so bad, the message for adding one string is:
LB_ADDSTRING
So something like:
SendMessage(
(HWND) hWnd,
LB_ADDSTRING,
(WPARAM) wParam,
(LPARAM) lParam
);

Hi,
How do we minize a dialog at the startup i've tried to use
showwindow(SW_MINIMIZE)
in the initdialog but with futile results has anyone done this before will be grateful for any help
Thanks.

The easiest way is to create the dialog with the WS_MINIMIZE style. One way to do this is to add this style to the dialog template. You may need to edit the .rc file directly in order to do this.

Yes, I'm still fumbling around with the basics of MFC. I've got a CSettings class of which I declare an instance "settings" as a member of CMyApp.
So I've got:
class CMyApp : public CWinApp<br />
{<br />
public:<br />
CSettings settings;<br />
}<br />
When someone selects Settings... from the menu, the framework calls CChildView::OnFileSettings().
How can I access the settinngs I've got stored in CMyApp::settings ? AfxGetApp() just returns a pointer to the base class, CWinApp.
Confused.

Well, there's probably a global variable named theApp around somewhere, otherwise just cast the return value of AfxGetApp() to a CMyApp* [edited: yeah, forgot about the <> thing):
CMyApp* pApp = static_cast<CMyApp*>(AfxGetApp());

Just do this ...
CMyApp * pApp = (CMyApp*)<code>AfxGetApp()</code>;
Best regrads,

The cast of the AfxGetApp will work but I think its a problem of the architecture. Why you should one (of many) CChildView objects modify an element of the app?
IMHO: delete the "CChildView::OnFileSettings()" and create the OnFileSettings() -Message-Handler in the Mainframe or App class.

I use COXHyperLink from Dundas Ultimate Toolbox to display two links. In Win2K/XP I have following problem: by default, this OS hides underlied letters on buttons/menus (these letters used for quick access with Alt, for example &Close). When I press Alt key, captions became underlined. COXHyperLink uses subclassing of static control.
TROUBLE:
After Alt pressing hyperlink disappears, and only gray background is visible. How can I fix the problem by myself?

Try to change the setting :
From the VC++ menu:
Project -> Settings...
Go to C/C++ tab, choose "Code generation" category.
Try other choices listed in "Use run-time library:",
for example: Debug ones or non debug ones, DLL ones or non DLL ones.....

How can i turn off the little blinking cursor in console c++?
i have a text game that is a big loop and the game field is stored to an array that is outputted, but when its run on slow computers u can see the cursor moving down in row in the array, is there a way to turn this off?
i asked a while back and Nish kindly gave me this code:
char abc[128];
int main(int argc, char* argv[]){
HANDLE h;
h= CreateConsoleScreenBuffer(GENERIC_WRITE|GENERIC_READ, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL,CONSOLE_TEXTMODE_BUFFER,NULL);
SetConsoleActiveScreenBuffer(h);
CONSOLE_cursor_INFO cci;
cci.dwSize = 90; cci.bVisible=false;
SetConsolecursorInfo(h,&cci);
cin >> abc;
but i couldn't get it to work within my specific program,
can anyone help me out?

After you check the case of some stuff there (struct name and function name), this code works as-is.

Ok THis should be really easy, but as you all know frustration is the number one killer of compurter keyboards, so i've given up. 
I have a loop that refreshes a OpenGl screen rendering contect.
What is the easiest and most reliable way to measure the the time taken to run through the loop I.E FPS. What time functions can I use to get the elapsed time in ms.
Thank you.

The highest resolution timer that you can get is from a call to QueryPerformanceCounter. If you divide the result from this value by the result you get from QueryPerformanceFrequency, you will have a value in milliseconds.
Not all machines have access to a performance counter, therefore your next best choice is the multimedia counter. You can access this with a call to timeGetTime.
There is a really good timer function that is written inside of a set of DirectX utility classes in the SDK. It can be found in the samples/multimedia/Common/src folder and it is the dxutil.cpp file.
Also in the d3dutil.cpp file of the same directory there is some good code to generate the fps for a render sequence.
Good Luck!

Thanks I am now using QueryPerformanceCounter
Works good. Max fps is 30 Min 12

Is this really true? I've heard it before, but I've actually never found a machine that lacks them.
What are they using? Why whouldn't they be available?
Please also note that the highest resolution "timer" you can get is the IA32 rdtsc instruction, though it's not strictly a "timer".

you could also use the ZEN timer class which makes use of the timer chip on your motherboard.
you can take the code from Michael Abrash's Graphics Programming Black Book, Special Edition
or
Michael Abrash's Zen of Code Optimization
according to my knowledge thats as far as you can get since it is dependent on the clock frquency your hardware is using.
Best of luck.
