Create two Win32 apps, tick 'use MFC' for one. Diff the files, and make sure you have all those things set in your own code.

DialogBar in a DLL? Please help!

Exe026-Oct-04 7:27

Hi there!

I've got a problem with a simple, self-written DialogBar.

The DialogBar is not amazing at all, it simply displays a Dialog in a dockable ControlBar and is part of a DLL. If I try to create the DialogBar (in my MainFrame-Class), it fails and the control bar can not be created.

After a little research, I found out that the following line in the MFC-Core failed:

 <br />
HWND hWnd = ::CreateWindowEx(cs.dwExStyle, cs.lpszClass,<br />
   cs.lpszName, cs.style, cs.x, cs.y, cs.cx, cs.cy,<br />
   cs.hwndParent, cs.hMenu, cs.hInstance, cs.lpCreateParams);<br />

Another strange thing I found out while researching:

 <br />
m_wndDialog.Create("bla fasel", this, 123456, WS_VISIBLE|WS_CHILD|CBRS_FLYBY|CBRS_SIZE_DYNAMIC|CBRS_TOOLTIPS)<br />

In that line a pointer to the parent window is passed to the Create() method (here this) of the DialogBar which is in the DLL.
If I verify the this-pointer before I enter the Create() method the member m_hWnd is valid and seems to be correct. But if I enter the Create() method (is a call to the DLL method), the m_hWnd of the parent window pointer becomes NULL.

Anybody out there with a solution to the problem?

Thanks in advance!

A method to collapse code in the IDE

While coding in C# in the Visual Studio .NET 2003 IDE, one is able to mark regions using #region and #endregion.

Is a similar option available when coding in Visual C++?

long compile time ... vs.net 2003 ...

Maximilien26-Oct-04 5:57

I have a project that is taking WAAAAYYYY too much time to compile... ( IMHO )

all files are C++ and are using precompile headers.

I use Program Database ( Zi ), minimal build ( and link ).

the only thing that I'm not sure, is that some of my source files are in subfolders of the main project file, and do

#include "../stdafx.h"

can that be a problem ?

also, there's a vc7.idb and vc7.pdb that are created ( and recreated ) quite often, I assume that the .pdb is the program database, but is it supposed to be recreated at every couple of files ?

THanks.

With minimal build and link enabled, it can take longer and longer to compile and link because certain files are hashed, instead of being rewitten every time. You might try a FULL rebuild (or rebuild all) periodically to keep this thrashing to a minimum. I see this same problem with VC 6.0 when I have incremental link enabled.

The PDB must correlate the lines in your source with the locations on the executables, so it is common for that to rebuild each time you recompile and relink.

BOOL Cfirstw32mfcApp::InitInstance()

SetRegistryKey(_T("Natural_Demon"));

this works perfect ...

the data retrieved from the registry is nicely update in the GUI
BOOL Cfirstw32mfcDlg::OnInitDialog()

..
...
...
..
EDIT1 = AfxGetApp()->GetProfileString("Settings", "email", "your login");
EDIT2 = AfxGetApp()->GetProfileString("Settings", "password", "details here..");
return FALSE; // return TRUE unless you set the focus to a control
}

this works perfectly ...

HRESULT Cfirstw32mfcDlg::OnButtonOK(IHTMLElement* /*pElement*/)
{
AfxGetApp()->WriteProfileString("Settings", "email", "hi");
AfxGetApp()->WriteProfileString("Settings", "password", "do");
return NULL;
}

but why doesn't this work ...?
HRESULT Cfirstw32mfcDlg::OnButtonOK(IHTMLElement* /*pElement*/)
{
UpdateData(FALSE);
AfxGetApp()->WriteProfileString("Settings", "email", EDIT1);
AfxGetApp()->WriteProfileString("Settings", "password", EDIT2);
return NULL;
}

if i do this ...
UpdateData();, UpdateData(FALSE); or this UpdateDialogControls(this, FALSE);
nothing works
EDIT1 en EDIT2 are empty and the registry get's updated with empty values.

where am i mistaking here?

Your Data Exchange handler function might not be set up correctly.

The Data Exchange might be overwriting the data in your edit field controls, or no member variables are setup to write into the controls.

It looks like you fill them in OnInitDialog, but you should do that in DoDataExchange.

You should be able to do all your data sets and retrievals within the DoDataExchange
similar to something like this:

void Cfirstw32mfcDlg::DoDataExchange(CDataExchange* pDX)
{
CDHtmlDialog::DoDataExchange(pDX);

// data TO controls, means LOAD strings with your existing data or default values
// you need to do this BEFORE the DDX_DHtml_ElementInnerText calls

if( !pDX->m_bSaveAndValidate ){
EDIT1 = AfxGetApp()->GetProfileString("Settings", "email", "your login");
EDIT2 = AfxGetApp()->GetProfileString("Settings", "password", "details here..");
}

// these calls presumably set or get the data from the controls into your string variables
DDX_DHtml_ElementInnerText(pDX, _T("email"), EDIT1);
DDX_DHtml_ElementInnerText(pDX, _T("password"), EDIT2);
DDX_DHtml_ElementInnerText(pDX, _T("Temp_Text1"), m_EDIT1);
DDX_DHtml_ElementInnerText(pDX, _T("Temp_Text2"), m_EDIT2);

// data FROM controls, means SAVE data from the controls to your storage
// you need to do this AFTER the DDX_DHtml_ElementInnerText calls
if( pDX->m_bSaveAndValidate ){

GetElementText(_T("email"));
AfxGetApp()->WriteProfileString("Settings", "email", EDIT1);

GetElementText(_T("password"));
AfxGetApp()->WriteProfileString("Settings", "password", EDIT2);
}

}

If the DoDataExchange is correctly implemented, you don't even need to have the OnOK handler, since the DoDataExchange will be called for you (I am pretty sure) and you definitely don't need the Cancel, because the UpdatData (and thus DoDataExchange) is not called at all.

Get Row & Column for a listCtrl

sweep12326-Oct-04 4:37

26-Oct-04 4:37

How do you determine the column on a listCtrl when you say double-click on the list.

I use the following to find the row:-

// Get the position of the selected item<br />
POSITION p = m_cAList.GetFirstSelectedItemPosition ();<br />
// Get the index of the selected item<br />
int row = m_cAList.GetNextSelectedItem (p);

I did think the use GetSelectedColumn() but GetSelectedColumn() gives the error:-

c:\C_Example\GenericDlg.cpp(602): error C2039: 'GetSelectedColumn' : is not a member of 'CListCtrl'

I have the listCtrl setup as a table with grid lines on and was going to use:-

int col = m_cAList.GetSelectedColumn();<br />
int index = (row * 16) + col;  // 5 rows by 16 cols

To obtain the position in the table.

Help?!? Confused | :confused:

Do you have a handler for the NM_DBLCLK message? If so, look at the iItem and iSubItem members of the NMITEMACTIVATE structure that is sent to the handler function.

Getting a bit lost here, Yes do have a handler for the double-click on the listCtrl:-

void CGenericDlg::OnNMDblclkList(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
/* This allows the user to double-click on a label and either select it or  de-select it as required.	*/<br />
// Get the position of the selected item<br />
POSITION p = m_cAList.GetFirstSelectedItemPosition ();<br />
// Get the index of the selected item<br />
m_cAList.GetNextSelectedItem (p);<br />
int row = m_cAList.GetNextSelectedItem (p);

Just wanted to know how to get the column here.

But if I now do (I think this is what you suggested)

NMITEMACTIVATE *lpnmitem = (LPNMITEMACTIVATE) pNMHDR;<br />
<br />
int col = lpnmitem->iSubItem;<br />
<br />
int row = lpnmitem->iItem;

Here the col is OK but the row is always set to -1.

ASAIK, you cannot find both row and column this directly. Use GetNextSelectedItem to retrieve the selected item index (the 'row') and the pNMHDR to retrieve the 'column' (as you did in your second method).

As for
sweep123 wrote:

-1 is the normal return value if you consider a subitem (see MSDN:

iItem Index of the list view item. If the item index is not used for the notification, this member will contain -1.)

-> you can only get information about one item _OR_ one subitem. Your list ctrl is not a grid, it is indeed a list.

I did manage to get the row and col of a list control by putting the option LVS_EX_FULLROWSELECT on for the list control, but it looks a little messy with one whole row selected. When I turn this setting off I aways get -1 for the row (item) and thats with GetNextSelectedItem() and pNMHDR methods.

I dont know a better way to get both the row and col of a list control.

I am sure someone will know of a neater solution.

You can use one of these.

www.teltone.com

http://www.teltone.com/products/simulators/tls3/home.htm

Teltone's TLS-3B is an inexpensive simulator that makes it easy to perform basic feature and performance testing of telecommunications equipment including:

Telephones
Modems
Faxes
Caller ID equipment
Anything that connects to a phone line!

The TLS-3B is Teltone's lowest-cost unit. You plug in a phone to one of the two ports, and you will think you are connected to the phone company! Dial the default or programmed phone number, and the other line will ring. It's like having a miniature public telephone network in a box.

The TLS-3B has programmable functions which allow you to configure features like caller ID, test tones, and hot line ringdown.

That's what I used to do.
