I have a CEdit control defined like so:

EDITTEXT        IDC_LOG,7,177,437,86,ES_MULTILINE | ES_AUTOVSCROLL | <br />
                ES_READONLY | WS_VSCROLL<br />

I add text to it like this:

bool CFLModManagerDlg::Log(CString text, bool NewLine)<br />
{<br />
	LogString += text;<br />
	if(NewLine)<br />
		LogString += "\r\n";<br />
	UpdateData(FALSE);<br />
	LogCtrl.SetSel(0,-1,FALSE);<br />
	//CEdit *Edit = (CEdit*)GetDlgItem(IDC_LOG);//->SendMessage(WM_COMMAND,EN_VSCROLL,((LPARAM)GetDlgItem(IDC_LOG)->m_hWnd));<br />
	//Edit->LineScroll(1);//Edit->GetLineCount());<br />
	//LogCtrl.LineScroll(-1);<br />
	//UpdateData(FALSE);<br />
	return false;<br />
}<br />

Now, no matter what I do to try to make it scroll to the bottom, it won't! What am I doing wrong?

Get Click from subcontroller

I Got an own custom controller.

Lets call it.

class CMyCtrl , public CWnd
{
public:
// ...
//
private:
CButton m_Btn;
};

and this controller creates the CButton ( m_Btn ) inside CMyCtrl dynamically.

How can CMyCtrl know if m_Btn is clicked ??

I Can subclass CButton and overload OnLButtonUp() and to
GetParent()->SendMessage(…) but I don’t want to. There must be a way to get CMyCtrl to get the information that a child window has been click or ??

ActiveX on Dialog breaks DialogBoxParam on Callback?

Does anyone know if it is a fact that ActiveX components such as a DataGrid on a Dialog breaks DialogBoxParam such that WM_INITDIALOG never gets called but instead immediately shuts-down (WM_DESTROY) the Dialog?

I am using code that does not use MFC. A friend says that COM (ActiveX) does NOT work in a non-MFC environment. Is there a workaround???

Networking woes...

I am trying to do something simple. A user types in a share name of a resource (e.g., \\Mycomputer\MyShare), and I want to validate it to make sure the resource actually exists before going any further.

Apparently, nobody else does this, becuase the documentation for all the Microsoft networking APIs sucks, and there are very few examples on the Net (I couldn't find anything relevant). Here are some of the things I've tried to do so far:

resource.dwType = RESOURCETYPE_PRINT;
resource.lpRemoteName = uncShareName.GetBuffer(0);

size = 0;
error = ::WNetGetResourceInformation(&resource, NULL, &size, NULL);

I always get error code 487 - Invalid address. (Of course, MSDN does not list this as an error that WNetGetResourceInformation should return.)

So then, I tried seeing if I could set the NETRESOURCE's lpProvider and perhaps that would make things go smoother. But this simple code:

DWORD size = 1000;
char provider[1000];
DWORD error;

error = ::WNetGetProviderName(WNNC_NET_MSNET, provider, &size);

always returns an error 1222, network cannot be found (network not present or cannot be found). Apparently my network type is wrong, but there are no others that look anywhere near correct.

For printers, I can use EnumPrinters and get it to work - but only if the remote server is Windows NT, 2000, or XP. It gives me an error, RPC Server unavailable, if I try to look for shares on a 9X machine.

One final piece of the puzzle - I know it is not a networking issue, becuase I can see any object I want using Windows Explorer or "Run" from the Start menu.

Any help would be appreciated.

Ah, nevermind, I figured it out. The key is to use WNetEnumResources.

Displaying Forms From A Visual Studio Macro

I am trying to find a way to display a form from a
Visual studio macro. I have opened the Macro IDE,
but cannot find a way to insert a form. Can anyone
tell me how to do this, or do I need to build an
add in for such a thing? (Coding the macro in VB)

Thanks,

NDP.

As far as I know, it's not possible in VC6. An add-in is your only option.

Print previewing Word document in Active Document Container

Martyn Pearson3-Apr-03 4:30

Martyn Pearson

3-Apr-03 4:30

The story so far...

Using MSVC 6.0, I've created an MDI MFC application, and selected "Container" compound document support. I also ticked the Active Document container checkbox.

I run the application, and insert an object from a file - an existing Word document - into my document. As expected, it shows the whole Word document in the application.

I then select Print Preview from the menu. The print preview window comes up, showing an empty document. The document content is now spewing out of my printer Roll eyes | :rolleyes:

So, does anyone know how to fix this so the content goes to the print preview DC, not the printer DC?

Thanks in advance

.NET FlatStyle equivilent in MFC

Hi,

I am trying to get XP alpha icons working in a ListView. I have created a manifest file which link to comctrl 6 but the XP style icons come out crappy. I have noticed in .NET there is a FlatStyle property that you need to set to FlatStyle.System to get it to work correctly.

How can I make XP Icons show correctly in MFC?

Thanks

DestroyWindow() and delete

ns3-Apr-03 4:11

I have a bunch of local MyCDlg windows that I made using: MyCDlg* pDlg = new MyCDlg that have their pointers in a stored in a vector. At some point I want to kill all these windows so I cycle through the vector and do

pVec[i]->DestroyWindow()

Right after the destroy is it okay to do "delete pVec[i];" ? Is that the way to do it?

Appreciate your help,
ns

That's like stopping a car by removing its key while driving. Smile | :)

The proper way to force a modal dialog to end itself is to post an IDOK (or IDCANCEL) WM_COMMAND to it. That will cause the proper cleanup actions to occur. You can then delete the saved pointer to your dialog class.

CTreeCtrl - OnSelChange()

3-Apr-03 3:36

Hi.
I've created a CTreeCtrl with a root and some subitems,
but want to get the 'psztext' member from a TVITEM struct.

MFC already created a pointer:
void ...::OnSelchangedTreeview(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;

//My Code
CString strText;
strText = (pNMTreeView->itemNew).pszText;
AfxMessageBox(strText);
}

I seem to get really weird ascii code while displaying the CString. Any1 knows what seems to be the problem?

Greetings
Jens

check the mask value of that itemNew structure, to make sure the pszText member is valid.

yes i have done that:
strPrevDate = strDate.Right(4);
tvItem.mask = TVIF_TEXT;
tvItem.pszText = strPrevDate.GetBuffer(3);
tvItem.cchTextMax = 32;
tvInsert.hParent = hRoot;
tvInsert.hInsertAfter = TVI_LAST;
tvInsert.item = tvItem;
hYearItem = m_treeCtrl.InsertItem(&tvInsert);

Forget about that crap, and try this instead:

CTreeCtrl& tree = GetTreeCtrl();
HTREEITEM hItem = tree.GetSelectedItem();
CString strText = tree.GetItemText(hItem);

Hi Alvaro

GetTreeCtrl() didn't work for me, i tried it out like this:
CTreeCtrl* pTreeCtrl = (CTreeCtrl*) GetDlgItem(IDC_TREEVIEW);
HTREEITEM hItem = pTreeCtrl->GetSelectedItem();
CString strText = pTreeCtrl->GetItemText(hItem);

I now get the text correctly, thanks Smile | :)

But now, i want to know with which kind of 'level' we are talking about: root, child or 'child of child'

Any1 any idea?

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