 I am creating an MFC application with activeX document server support. The application runs perfectly fine when i run as a standalone application. But when i run the application in Internet explorer,
it opens however opening a form from the top menubar, it gives an error "access violation reading
location" having error code 0xC0000005 (Running in standalone mode does not give this error).
I have used global pointers to the objects I need.
In application class, i have declared a object as
TestClass* tm; //tm is a global pointer to TestClass
In application class, InitInstance() function i initialize the pointer as
tm = new TestClass();
AND i call the following code on Menu click as
{
tm->doModal();
}
I get the access violation error when i call DoModal().
I have to use tm as a global pointer to TestClass since using
local pointer has not worked. If you have any workaround, please help.
Thanks.

Is there a more standard way from within MFC to get the current working directory? What I’m using is _getcwd(buff, 50). It does the job, but I’m wondering if I should be using something else (which I can’t as now find)?
Thanks,
Ilan

Platform SDK call:
TCHAR szDirectory[MAX_PATH] = "";
::GetCurrentDirectory(sizeof(szDirectory) - 1, szDirectory);

I have a ClistCtrl with three columns how do i select wich colum i want to insert my string.
Each time i insert a String it is inserted in the same column (1):
int a;
a = m_F.m_SN.GetCount()-1;
while (a>0)
{
S = m_F.m_SN.GetAt(m_F.m_SN.FindIndex(a));
CLC.InsertItem(a,S.SNUPS,0);
CLC.InsertItem(a,S.SNRand,1);
CLC.InsertItem(a,S.SNDevice,2);
a--;
}

You have to fill the LVITEM structure:
<br />
LVITEM lvi;<br />
CString csText = "Hi !!";<br />
<br />
lvi.iItem = 0;
lvi.iSubItem = 1;
lvi.mask = LVIF_TEXT;
lvi.pszText = csText.GetBuffer(0);<br />
CLC.InsertItem(&lvi);<br />
For a complete guide Using the List Control

I hope it helps,

Hi,
InsertItem, adds an item to the listcontrol, this is a full line in the list view and is in fact the text of the first column.
The text in the other columns (2 and further) is call subitems.
int nIndex = 1;
nIndex = c_listcontrol.InsertItem(nIndex, "placed in first column");
// use the new index because we dont know where the actual item is added in the listview,
// due to sorting and so.
// add to second column, 1: subindex is zero based
c_listcontrol.SetItemText(nIndex, 1, "placed in second column");
// add to third column, 2:
c_listcontrol.SetItemText(nIndex, 2, "placed in third column");
Regards

I have written the following piece of code into my project. But it is giving me assertion error. Can anyone tell me what is problem in it?
void CPungaDlg::OnBUTBrw()
{
CFileDialog find(true, NULL, NULL, OFN_EXPLORER, NULL, NULL);
find.DoModal();
CString filename = find.GetFolderPath();
m_name = filename; //prints address in edit box.
UpdateData(false);
}

Strange  cause even GetFolderPath is only valid for an Explorer-style window you have provided this style ... and it crashes

The assertion is this, right?
CString CFileDialog::GetFolderPath() const
{
ASSERT(::IsWindow(m_hWnd));
[...]
}
It means that calling CFileDialog::GetFolderPath is only allowed while the file dialog is active, and not after DoModal has returned, as it is your case.
If you are only interested in the folder for the selected file, consider using SHBrowseForFolder instead of CFileDialog.

Ups !!! I think you'll have to remove them one by one looping through the CList, using GetCount and IsEmpty and RemoveTail, RemoveHead or RemoveAt.

i need to update a list view with DateTme..which is in FILETIME struct.How can i convert it to string ?
Thanks

Using FileTimeToSystemTime[^] you have a SYSTEMTIME var with all the info:
From msdn:[^]
<br />
FILETIME ftCreate, ftAccess, ftWrite;<br />
SYSTEMTIME stUTC, stLocal;<br />
LPTSTR lpszString;<br />
<br />
GetFileTime(hFile, &ftCreate, &ftAccess, &ftWrite)<br />
FileTimeToSystemTime(&ftWrite, &stUTC);<br />
wsprintf(lpszString, TEXT("%02d/%02d/%d %02d:%02d"),<br />
stLocal.wMonth, stLocal.wDay, stLocal.wYear,<br />
stLocal.wHour, stLocal.wMinute);<br />

Hello,
I've got a little problem... seams I do not have realy understand how CMenu work.
I'm creating menu by hand using such method :
<br />
BOOL menuTest = m_cMenu.CreateMenu();<br />
MENUITEMINFO menuItemInfo;<br />
menuItemInfo.cbSize = sizeof(MENUITEMINFO);<br />
menuItemInfo.fMask = MIIM_ID;<br />
<br />
menuTest = fileMenu.CreatePopupMenu();<br />
if ( menuTest == TRUE ) {<br />
LoadString(AfxGetInstanceHandle(), IDS_NOUVEAU, projectPrefix, MAX_PATH);<br />
fileMenu.AppendMenu(MF_STRING | MF_ENABLED, IDS_PROJECT_ID_BASE+IDS_NOUVEAU, projectPrefix);<br />
<br />
LoadString(AfxGetInstanceHandle(), IDS_OUVRIR, projectPrefix, MAX_PATH);<br />
fileMenu.AppendMenu(MF_STRING | MF_ENABLED, IDS_PROJECT_ID_BASE+IDS_OUVRIR, projectPrefix);<br />
<br />
...<br />
<br />
LoadString(AfxGetInstanceHandle(), IDS_FICHIER, projectPrefix, MAX_PATH);<br />
m_cMenu.AppendMenu(MF_POPUP, (UINT)fileMenu.m_hMenu, projectPrefix);<br />
<br />
menuItemInfo.wID = IDS_PROJECT_ID_BASE+IDS_FICHIER;<br />
menuTest = m_cMenu.SetMenuItemInfo( pos++, &menuItemInfo, TRUE );<br />
}<br />
<br />
...<br />
<br />
SetMenu(&m_cMenu);<br />
Doing this, menu is created with success. One problem is all element appear grayed.
So I've seen later, that added ON_COMMAND( IDS_PROJECT_ID+IDS_NOUVEAU, OnMyMenuCommand ) would active them.
So I've added a ON_COMMAND_EX_RANGE with range of menu id (I dislike this method...), but then ALL of my menu item are activated, whereas they have been create with MF_GRAYED or MF_DISABLED.
So, my question is, how to build menu ? and how to make them work normaly, responding to standard OnMenu... method ???
Tx by advance,

Hi again, it seems the problem just come from the display of the menu.
When I check for the menuItem state, it is well in the creation state...
do not understand
