1. DT_CALCRECT will make the rect fit the size of the text drawn without any actual drawing. If you don't specify this switch, I think DrawText leaves the rect untouched.
2. Unless otherwise noted, functions tend to behave the same across OSs. I don't see any reason to think this is different for DrawText. Have you detected any anomaly?

Hi there and thanks a lot, Joaquin! But I do think that DrawText(...) do fit this rect to the overall size of the text.
I did an experiment on a dialog-based program with a grey background. I called CDC::DrawText(...) as in :
<br />
void CMyProgramDlg::OnPaint()<br />
{<br />
else<br />
{<br />
CPaintDC dc(this);<br />
dc.DrawText("I am Xeon.",CRect(10,10,1000,1000),NULL);<br />
CDialog::OnPaint();<br />
}<br />
}
And guess what? The text is drawn within a rectangle that fits the text exactly, cos' u see, the background color of the text is white, and the style is OPQAUE. And white against a grey background, we can easily see the size of the rect used to hold the text.

No.....I haven't a chance to detect any anomalies, cos' I don't have more than 1 OS to test out. But 'm always really suspicious of a same program running on different Windows OSes. I've heard that lotsof programs behave in different ways across different OSes, and that's a total headache.

Hi All - I'd love to know how I can get DevStudio VC6 to fire calls at my Addin's OnIdle() method - or at least to tell me somehow it's not doing anything and that I could do something during idle time.
Since the addin's are not allowed to run their own message pump (aka DevStudio application model is not thread safe) I can't just go ahead and slap a message queue in there with a thread to manage it.
What I've got is a socket connection to another server WITHIN MY ADDIN, and I want to be able to check whether there's any input on the socket during idle time.
I was also wondering if I could create a another thread then kinda 'post' messages across this thread boundary - but it requires that I hook something into the DevStudio message loop - which I don't know how to get hold of.
Any help is massively appreciated! Thank you.

Anyone know how to do this?
Spy shows the system tray as a single window (with no children) so getting the window rect for that is no problem but can I then locate where my icon is within the systray?

I have very strange behaviour of application. It´s transfer of data with TCP/IP. I´m using ovellaped WSARecv, WSASend. There was no problem on Windows 98, NT 4, 2000...but on XP it doesn´t work. For example, when transferring data block whom size exceed 3760 bytes, on W2000 is complete, but on XP is limited to 3760. I´m talking about tests on local machine, but on network was result similar(i´dont know exactly how many bytes was transferred).
Sorry, my English it´s not very good, but I believe you understand

Maybe just the XP stack has a lower MTU? Start by checking that (getsockopt with SO_MAX_MSG_SIZE).

Thanks but...maybe I said it wrong, I talked about connection oriented socket, not UDP.

Jesus!!! Does this code work???
<br />
(_bstr_t)"DATABASE/TABLE[@Left]"<br />
What is this? Never, never do like this. Do:
<br />
_bstr_t(OLESTR("DATABASE/TABLE[@Left]"))<br />
<br />
pIXMLDOMNode->Release();<br />
pIXMLDOMNode=NULL;<br />
It's not bad, but pIXMLDOMNode = 0 is enough.
<br />
(LPARAM)(char *)(_bstr_t)Tablename<br />
Should be:
<br />
reinterpret_cast<LPARAM>(static_cast<TCHAR*>(_bstr_t(Tablename)))<br />
Such a bad cast should be explicit.
<br />
pIXMLDOMNode->get_attributes(&pIXMLDOMNamedNodeMap1);<br />
You are working with very smart pointer. Instead, do like this:
<br />
pIXMLDOMNamedNodeMap1 = pIXMLDOMNode->attributes;<br />
What is:
<br />
CHECK_AND_RELEASE(pIXMLDOMDocument2);<br />
May be it a:
<br />
#define CHECK_AND_RELEASE(x) x->AddRef()<br />
I don't know.
Summary.
1. Never, never use c-casts (like (_bstr_t)x, (LPARAM)y, etc). They are the worst evil, unless you damn sure that you do. It's very hard to find a bug in a such code.
2. Read about _com_ptr_t. Learn how it's intended to use.
3. Avoid macros.
4. Optional, but strongly recommended. Get a Stroustrup.

Does someone know a simple way? Or does someone know a place where i can download a Control, which i can add to my project.
Thank you,

hi
is there a way to copy a file to the same directory and renaming the file all in one. I've tried CFile::Copy, then rename, then copy again, but it seems a bit clumsy...
Thanks

What exactly do you want to accomplish? Say you have a folder :- c:\abc. Now say you have a file one.gif. You want to copy c:\abc\one.gif to c:abc\two.gif and then rename one.gif to something else??? Is that what you want to do? If so, copy abc.gif to one.gif. Now rename abc.gif to whatever.gif! Pardon me if I misinterpreted your requirement.

jip
c:\file1.txt must become c:file2.txt

Or use ShFileOperation, which I think let you move/copy files when they are open.

I'm preparing to develop a web stress testing software.Could someone give me some advices, such as how to realistically reproduce multiple
browsers requesting pages from a web application, what technologies should we adopt...
Our software is aiming to realize three main fonctions:
1. simulate a request to the web server, and trace the process, in order to see if the web
application works normally. If there is a problem, we could know where is it. web server?
database? etc
2. automatize the test, that means to set the test automatically executed in a fix time.
3. simulate multiple users send the request to a website simultaneously, to verify if the web
application works properly under a given enough great number of users.
Thanks a lots!

This can be done using multiple threads. Start n threads and get them all to attack a particular portion of the web site at the same time.

You can either feed in a predefined set of URLs. Or you can parse the URLs in a web page and go to each of them automatically. And you'd also have to populate the form text and other fields with random data (sounds rather like a lot of work to me).

I doubt if you can locate the error precisely. It might be a db error but the error might be due to buggy server side scripting.

Hi there,
I want to capture screenshot as well as keystrokes pressed in DOS mode. I have worked on Windows API for achieving these results. It is working fine in case of windows application. I just want to know why it is not happening in DOS promp mode. Is there anyway to achieve this.
I need expert guidance from all of you before reaching any conclusion on this part.
Thanks in advance,
Shitij.

I just write this code in my initdialog of my dialogbox.so whenever i open this code,the memory size is increased.iam writing this code in win32application.Not an MFC Code.What might be the reason for memory leak above.

IXMLDOMNamedNodeMap* pXMLNamedNodeMap=NULL;
IXMLDOMNodeList* pXMLNodeList=NULL;
IXMLDOMNode* pXMLAttNode=NULL;

long lCount;
VARIANT_BOOL bIsSuccessful;
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_DOMDocument, NULL, CLSCTX_INPROC_SERVER,

if (FAILED(hr))
return(hr);
if(hr)
{
pXMLDoc=NULL;
pXMLDoc->Release();
