CListCtrl with static columns.

Hi,

I am looking for an example of a CListCtrl derived class
which implements static columns. These are columns which
are excluded from a horizontal scroll, so it is possible
to scroll horizontal through a large list control, leaving
some important columns permanently in view. Can anybody help
me to a link or say how exactly it is done.

tia.

Listbox control variable ??

I am trying to read a file and write its contents to a listbox control.

However, the listbox control variable is not recognized within the 'click' event of the button.

void CSentenceTestDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_DISPLAY, m_Display); // m_Display is the control variable for the listbox
}

...

void CSentenceTestDlg::OnBnClickedTest()
{

//m_Display returns a synthax error when typed here!!
}

Unsure | :~

Can you be more specific ON_LBN_SELCHANGE(IDC_LIST2, OnLbnSelchangeList2)when you click
in a listbox you have a event ON_LBN_SELCHANGE now what do you need

Please help me how to delete all files or how to get the file names of all files in a directory.

Same as in UNIX, can I use (DIR structure) or different method should be followed?

You can use FindFirstFile /FindNextFile in the loop and you can use form DeleteFile

How to create a CScrollView window from my own class

abednego0022-Jul-06 16:44

22-Jul-06 16:44

I am trying to make my own class that, when called/instantiated from a program, will create its own window that has the CScrollView properties. I do not need menus, toolbars, or anything fancy... I just need it create a window on which to draw on that is a certain size (pixel x pixel), to be able to draw simple vectors, and have the ability to scroll if the drawing gets bigger than the window.

Basically, if I call the class and set the size of the window to be 400x400 pixels big, it creates a CScrollView window to that size, and gets ready to draw vectors using the MoveTo and LineTo functions in the OnDraw class.

Online searching on MSDN and this forum, as well as many books from the bookstore have not been able to get me a working program...

Any help would be much appreciated, and I thank you all in advance for any aid provided!

Thanks,
dan

Hi all

i have a code where i am starting the process from a windows service that i created. Now i want to terminate that process using some other application(MFC stand alone) application. But when ever i try to do that,it gives error 5 which documentation says is "Error Access Denied"......here r the codes that i m using for creating and stopping the process

1)Creating a process

success = ::CreateProcess(temp,cmdstr,0,0,FALSE,CREATE_NEW_CONSOLE,0,0,&startupinfo,&procinfo);

where temp and cmdstr are application path and command line argument that i pass

2) terminating process

HANDLE hn = ::OpenProcess(PROCESS_ALL_ACCESS,false,id);

if(hn != NULL)

{

::TerminateProcess(hn,0);

}

now here OpenProcess API fails and gives error........id is the process id of the process i started using a service......please suggest me a way out of this.

thanks

The MSDN documentation here suggests that if you are trying to do OpenProcess with all access, you need to enable SeDebugPrivilege privilege. This is because all PROCESS_ALL_ACCESS includes access like reading/writing the target process' address space which is a privilege normally reserved for debuggers.

If all you are doing is terminating the process, you should specify the minimum amount of access required to do that.
