I don't think this is going to be an easy task. Different versions of windows (even service packs) have different dialogs and setup. I think Win 2K+ comes with TCP/IP installed by default. As for the IP address there are programs on this site that will do that for you. One thing to note is you can not assume that a person has 1 network card they may have 0 or 2.

Where is GDI+ 1.1

Does anyone know if GDI+ 1.1 is included in the latest platform SDK. It is not part of VS.NET 2003 which is still using 1.0. The MSDN doco refers to 1.1 for a number of classes that I'm interested in.

There seems to be no information about it on the MSDN website (although it's hard to tell with the current search engine).

A few postings in newsgroups seem to indicate that the only source of this at the time of writing is as part of one of the Office 2003 products, does anyone know if this is the case.

I think it should come with the latest Platform SDK. I have it, and I think I got it by downloading the Windows Server 2003 RC2 SDK.

How do you know you have version 1.1 ?
None of the headers i have contain version information.
The dll version is 5.1.3097.0 which doesn't tell me if it's version 1.0 or 1.1 of the API.

I have the Feb.2003 Platform SDK installed.

Communicating with a serial port

Up until this time, i've been programming with turbo c from 100 years ago, and i haven't had any luck communicating with a meter. The code is not the problem, we've gotten similar programs to work, but we want to try using c++ to code in.

I've been using the bioscom() function of tc, which is very easy, but now that we're looking at c++, i haven't found anything similar.

Can someone point me to somewhere that has a general description of how so use c++ to communicate with a serial port?

I'm using rs232 library under C++ Builder. Library is WinAPI abstraction. If you are using VC++ you can use it as an example, to write your own library. I put it here:

In Win32 API you use CreateFile() to open the port. Look at the docs for that. ReadFile() and WriteFile() are used to send and receive data. CloseHandle() closes the port.

How to open a file in its designated application?

Hi there,
I have the complete path of a file in a CString variable and I want that first the appropriate application should be executed and then the file should be opened.

For ex,
If the file name is "abc.doc" then first the application MS-WORD should be invoked and then the file should open in it.

Please tell me how to do this. Confused | :confused:

SetFocus??

Hi,

I have a Dialogbar with some edit control into it. I want to set the focus on the first one. The focus seem to work right because the caret appear in the first edit control but my text in the control is not selected. what am I doing wrong? I would like to have the text selected so that I could change my text into the control without having to delete it first.

thanks for helping

Are you calling MyEdit.SetSel(0, -1); ?
This should select the whole text content of your edit box.

[EDIT]This is the same as calling

::SendMessage( 
  (HWND) hWnd,       // handle to destination window 
  EM_SETSEL,         // message to send
  (WPARAM) 0,        // starting position
  (LPARAM) -1        // ending position
);

I have the same kind of problem ...

when my editbox received the focus, I want to select all text in it.

ON_EN_SETFOCUS(CMbCoordEdit::IDC_EDIT2, OnSetfocusControl2)
...

void CMbCoordCtrl::OnSetfocusControl2()
{
  m_edit2.SetSel( 0, -1);
}

That doesn't work when clicking in the editbox.

Setting the selection manually from another function works, but not like that.

any hints ?

Thanks.

Migrate from printf to streams in my logfile class.

justin2235-Aug-03 2:34

Hello

I've written a logfile class that writes the logentries in xml format.

A typical usage:
mylog.WriteLog(LOG_PRIO_HIGH, "Agroup", "This is a text with %d some %s
vars", 34, "diffrent");

output
<entry date="2003-01-01" time="20:01:32:1234" prio="1"
group="Agroup">This is a text with 39 some diffrent vars</entry>

I want to accomplish the same thing by using streams/stringbuf.
But I've not found any good examples that show me how I should do.
What i've found is a couple of examples that derives a class from stringbuf and from ostream.

I would be nice of I can get something like this:

log << log_prio(1) << log_group("test") << "hello" << nIntVar << strBuf << log_end;
log << "this is a string";
log << " something more" << log_end;
log << log_prio(2) << "last line" << log_end;

would look like:
<entry date="2003-01-01" time="20:01:32:1234" prio="1" group="test">hello1yeye</entry>
<entry date="2003-01-01" time="20:01:32:2200" prio="1" group="test">this is a string something more</entry>
<entry date="2003-01-01" time="20:01:32:6600" prio="2" group="test">last line</entry>

How do I accomplish this?

Thanks,
Jonas

Hi All,
suppose we are on IE and we right click to open the new ie window there or use shift + click...that opens IE in new window..I want to implement such a thing that when anyone clicks on a link that opens new window or he intentionally opens it in new window..the new window shud not appear..I found something like:::
void CDWebBrowserEvents::OnNewWindow(BSTR URL, long Flags, BSTR TargetFrameName, VARIANT* PostData, BSTR Headers, BOOL FAR* Processed)
{
if (m_Browser) {
COleVariant varEmpty;
*Processed = TRUE;
m_Browser->Navigate((LPCSTR)URL, &varEmpty, &varEmpty, &varEmpty, &varEmpty);
}
}

this function call doesnt seem to work as..when I click on new window..the event is fired...but it shows an exception in *processed=true; I tried changing the definition of newwindow..but that also doesnt work becz then the function never gets called...I need it very urgently...Any help or pointers are highly appreciated..Thanks a lot in advance..

If you are getting an exception at: *Processed = TRUE; then I would assume Processed is NULL and you need:

if ( Processed != NULL )
    *Processed = TRUE;

Not testing pointers for NULL is a dangerous game to play.

Hi Neville,
I have developed an application and I want to load it at startup..I have
done that..but it takes some time to load..I want the process to be fast and
user is not able to access the desktop in the meantime before seeing my
application..is there anyone who can help me out..any help or pointers are
highly appreciated..Thanks a lot in advance..I am on win2000. And I really
need to do it fast..plz help

there is another small problem..I am using a webbrowser control to open
IE..and I want that when user clicks on a link that opens a new window or
just rightclicks to open in new window..the new window should not
appear..there I got some code which does that...which is like::
DISP_FUNCTION_ID(CWebBrowser2, "NewWindow2",DISPID_NEWWINDOW2,
OnNewWindow2, VT_EMPTY, VTS_DISPATCH VTS_PBOOL)
DISP_FUNCTION_ID(CWebBrowser2, "NewWindow2",DISPID_NEWWINDOW2,
OnNewWindow2, VT_EMPTY, VTS_BSTR VTS_I4 VTS_BSTR VTS_PVARIANT VTS_BSTR
VTS_PBOOL)
When i use first def. it works ok and putting cancel=true works and no new
window opens. but that breaks th eexecution of program and hence i need to
open the same url in parent window..so when i use second definition the
function is never called..I want to know whether there is anything wrong
with the definition or what..whatever u said must work..but if once the
function is called then only i will be able to know that it is working or
not..m_pBrowserApp is an object of IWebBrowser2..
virtual void OnNewWindow2(LPDISPATCH FAR* ppDisp, BOOL* Cancel);
// virtual void OnNewWindow2(BSTR URL, long Flags, BSTR
TargetFrameName,VARIANT* PostData, BSTR Headers, BOOL FAR* Processed);
Please let me know where I am wrong..
Thanks a lot..waiting for ur reply..

Re. slow startup, you need to work out where the bottleneck is and why. Profiling is one way to do this. I use a product called Glowcode www.glowcode.com[^] for this. Once you establish the bottleneck you can do something about it.

Re. OnNewWondow2() have a look at the MS articles:
"Keep Passing the Open Windows" about half way down http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwebteam/html/webteam02052001.asp[^] and "Microsoft Knowledge Base Article - 184876 HOWTO: Use the WebBrowser Control NewWindow2 Event" http://support.microsoft.com/default.aspx?scid=kb;en-us;Q184876[^]

Hi all, I have a simple dialog class that has a combo box, and a few edit ctrls, i connect them to CEdit and CComboBox classes etc. and i have my dialog catch the combobox events by COMMAND_ID_HANDLER(IDC_COMBO, OnCombo) and in OnCombo, depending on what they select i fill in the other edit ctrls with values, and i want to set the combobox ctrl text to a different value then what was selected by the user. but whenever i try this, just by CComboBox.SetWindowText("blah") it never works, all the other editctrls change to what i set them, but not the combobox. any ideas anyone ?
thanks

Position cursor on last item in CListCtrl (reportmode)

Wim Jans5-Aug-03 1:48

Hello all,

I'm having troubles positioning my current record indicator programmicaly on the last record.
Let's say I have a CListCtrl in report mode, Filled with some records.

I have a button which inserts a new record in the list, and I want to position the record indicator (that blue line) on the newly inserted record.

I tried:

m_cListCtrl.EnsureVisible(m_cListCtrl.GetItemCount()-1, FALSE);<br />
m_cListCtrl.SetItemState(m_cListCtrl.GetItemCount()-1, LVIS_SELECTED, LVIS_SELECTED);<br />
m_cListCtrl.SetSelectionMark(m_cListCtrl.GetItemCount()-1);<br />

which shows me the record, the blue line is in the correct position, but my focus isn't. When I press Up, the record indicator jumps back 2 positions.

What is the correct way to do this positioning?
