There are plenty of articles on doing this in MSDN magazine.
Also if you search for 'under the hood' in msdev help
you will find articles by JOhn Robbins, Matt Pietrek etc
on doing this sort of thing.
Setting exception handlers that then show you the call stack.
Search for SuperASSERT written by John Robbins, which shows
you the stack.
MFC also provides a AfxDumpStack().
Win32 provides StackWalk(), there was a similar function in Win16.

Is is possible to set CListCtrl row height to zero? I want to hide some rows. I was wondering if this could be done without having to make my own owner-drawn control.

Im in the midle of making a CD player for windows and im doing it in the style of sonique (ie it does not look like a standard windows progam) I want the have a semi transparent display for part of it.
Now the problem:
For the display to be semi transparent I will need to draw what is under the transparent area.
Posible solution 1 -
I could set the transparent display as part of my aplications region. But this will then mean that it will not draw the windows underneath if a change ocurs.
Posible solution 2 -
If I draw the transparent region to the main desktops DC, it will have to be continusly refreshed just incase it is over draw. This will cause a flickering and and a lot of wasted CPU cycles.
Unless there is a way of dectecting when windows has redrawn in the area of question.
Or is there another way that I'm not thinking off.
PS I am not using MFC
Any help would be much apresiated

Suggestion -: Cheat,
Build your main window as transparent ,
The place a Control or new irregular shape window on top of
the main window,

Hi
I have to create an ActiveX Dll using VC++ and I'm fairly new to this. I've a IDL file and a TLB file with me. I need to create a C++ dll using MFC with those interfaces.
How do I go about it? Please help me with this. If you can point out some sources of information for this that would be good too.
Thanks in advance

Looking for source code for a minimal FTP server (MFC based). Anybody can help?
|
|
|

The codeproject seems to have some network examples under "Internet/Network".
In particular ...

JGAA offers the source to the now defunct version 2.0 of his WarFTP Daemon.
His server is a bit advanced, but it will give you a good idea of how to multithread winsock connections and handle file transfers as a server.
You can download the server source here: (URL) may be wrapped.

I am trying to handcraft an ADO recordset (that has no connection to a database using VC++). The code below is my latest attempt, but the Open fails. I'm sure this can be done, but I am missing a piece of the jigsaw. All the examples I can find are written in VB. Please can any one help ?
ADODB::_RecordsetPtr pRecordset;
pRecordset.CreateInstance(__uuidof(ADODB::Recordset));
// Use client side caching.
pRecordset->CursorLocation = ADODB::adUseClient;
ADODB::FieldAttributeEnum attrEnum = ADODB::adFldUpdatable;
// Add first field
_bstr_t bstrField1(TEXT("Field 1"));
pRecordset->Fields->Append(bstrField1, ADODB::adBSTR, 10,
attrEnum);
// Add second field
_bstr_t bstrField2(TEXT("Field 2"));
pRecordset->Fields->Append(bstrField2, ADODB::adBSTR, 10,
attrEnum);
_variant_t varSource;
_variant_t varActiveConn;
try
{
if (SUCCEEDED(pRecordset->Open(varSource, varActiveConn,
ADODB::adOpenStatic,
ADODB::adLockOptimistic,
ADODB::adCmdText | ADODB::adExecuteNoRecords)))
{
pRecordset->AddNew();
pRecordset->GetFields()->GetItem("Field 1")->
PutValue("1");
pRecordset->GetFields()->GetItem("Field 2")->
PutValue("1");
pRecordset->Update();
pRecordset->AddNew();
pRecordset->GetFields()->GetItem("Field 1")->
PutValue("2");
pRecordset->GetFields()->GetItem("Field 2")->
PutValue("2");
pRecordset->Update();
}
else
{
}
}
catch (_com_error e)
{
_ tprintf(_T("(ExecuteReturnRecordset) Error (0x%08x, 0x%08x): %s\n"), e.Error(), e.WCode(), e.ErrorMessage());
}

Hello,
I was wondering if somebody can give me some basic instructions on how to put a toolbar on an ATL composite control. Please note that I'm not using MFC in my project. A link to a sample would also be fine...
Any help is greatly appreceated.

I'm using CreateProcess() to create a new process for running a batch file. However the batch file contains command line to run another batch file. I would like to hide all the DOS window since it's the backend processing.
I have successfully made the DOS window for the first batch file hidden since I use CreateProcess() and set the attribute wShowWindow of STARTUPINFO to SW_HIDE. However, the DOS window for the second batch file (which is called to run within the first batch file) is not hidden.
How can I make the DOS window for the second batch file hidden as well?
Thank you very much and best regards.

I'm not sure if you can.
I tried this a while back in a console app. Because the application wasnt started via CreateProcess, I couldnt hide the console window.
Maybe you could use a multiline edit control in a dialog to simulate the 1st batch file in your application and use that to call the second batch file using CreateProcess. From there you know how to hide the console window.
Perhaps someone else knows if this is possible. As far as I know its not.
Let me know if you figure this one out!
Cheers!

Good Day!
In Visual Studio, the ClassWizard provides a tab for message handlers that creates the necessary function declaration and skeleton of implementation.
HTH.

I think I understand what you want to do...try subclassing the dialog listbox controls.
First derive a new class for each of the three listboxes from CListBox.
CMyListBox1
CMyListBox2
CMyListBox3
Then, in your dialog's main header file (mydlg.h, or whatever) change the default from:
CListBox m_ListBox1;
CListBox m_ListBox2;
CListBox m_ListBox3;
to:
CMyListBox1 m_ListBox1;
CMyListBox2 m_ListBox2;
CMyListBox3 m_ListBox3;
Don't forget to #include the CMyListBox(x).h files in your code.
Then, from your dialog's OnInitDialog function, subclass the controls using this code:
VERIFY(m_ListBox1.SubclassDlgItem(IDC_LISTBOX1, this));
VERIFY(m_ListBox2.SubclassDlgItem(IDC_LISTBOX2, this));
VERIFY(m_ListBox3.SubclassDlgItem(IDC_LISTBOX3, this));
Finally, then you can handle the OnSelChange event in your CListBox derived classes. So, you really don't add the function to the dialog class, you make it so you can handle the function from within that class.
Good Luck,
Frank

Hi all,
is it possible to have language specific dll's only with the resources in it, like dialogs, menus and stringtable. But the dialog classes for these dialogs in the main application?
Because i want to load the dll at runtime to have the language the user specified as interface language. That means, differnt languages for the dialogs but only one dialog class.
TIA, chris

Yes, this works easy using MFC, and you need to do a little more work with regular Win32 programming.
Use AfxSetResourceHandle() with MFC, use the handle to the loaded resource DLL in the regular Win32 dialog calls.
