There is a variation of the GDI+ Graphics class method "MeasureString" that has an optional parameter "codepointsFitted" that is a pointer to an INT. The documentation states that it is supposed to receive the number of code points that were actually fit into the layout rectangle.
When I try to use this "codepointsFitted" parameter, the INT that is pointed to always has the character count of the input string regardless of whether it indicates that the text bounding rect is larger than the text layout rect.
Has anyone ever gotten this variation of "MeasureString" using the "codepointsFitted" parameter to work? If so, what is the trick to getting that parameter to populate with the correct value?
Status MeasureString(
const WCHAR *string,
INT length,
const Font *font,
const SizeF &layoutRectSize,
const StringFormat *stringFormat,
SizeF *size,
INT *codepointsFitted,
INT *linesFilled
) const;

Seems to be working fine for me. The layout rect you are passing probably has enough width + height to hold all of your characters. Keep in mind that MeasureString will utilize *all* available space including height. So when it runs out of width it continues to render the text onto the next line. Pass it a HUGE string with a BIG font and see if you get the same results.
My test code:
RectF rSize;
INT iFitted;
INT iLines;
StringFormat format;
format.SetAlignment(StringAlignmentNear);
Font fontBold(L"Arial", 32, FontStyleBold);
CRect rcWin;
GetWindowRect(&rcWin);
RectF rgd(rctWin.left,rctWin.top,rctWin.right,rctWin.top + 32);
graphics.MeasureString(L"Test-Test-Test",-1,&fontBold,rgd,&format,&rSize,&iFitted,&iLines);
I copied and pasted that "Test-Test-Test" string about 20 times back to back to make my string bigger. The function correctly returns how many characers it was able to fit into the rect.

I thought I had tried everything. You reminded me that I needed one additional tweak to my format flag. I had "StringFormatFlagsNoClip" in there and it was apparently causing the issue.
Thanks for taking the time to help me out. It is greatly appreciated.

No problem, I just happened to be working in GDI+ when I came across your post.

As every one in the whole world knows, each PC has a "media access card" which is uniqe uneversally. I'd like to identify each system through Its MAC Number. can any one help me please?
Thank you masters!

By using GetAdaptersInfo() function, you could get MAC address. Check here[^] for code snippet.

Jijo.

Do you mean this: http://en.wikipedia.org/wiki/MAC_address[^]? If you do, a MAC address belongs to the network card in the computer (can also belong to a modem or other network-connected device), so if a computer has no network card it has no MAC address either, also if you change the network card (like, you buy a new one) you get a new MAC address, also these can be spoofed. Don't know if this applies to your case or not or if this is usefull information for you or not, but i thought i mention it, maybe it helps some way to clear up possible misunderstandings. Good luck with whatever you are doing.

Here i listed two ways. If any way is best why?
class MyClass
{
CString name;

what about
MyClass() : name(_T(""))
{
}

As far as i know CString's default constructor initializes it to an empty string anyways, so you don't have to do that explicitly. Or am i wrong?

Hi
Can I write a windows service and create a UI thread in it which should be able to identify / receive windows messages and process them? Is a window / dialog needed for a UI thread so that it can handle windows messages?
Thanx
|
|
|
|

Well, window messages can only be sent to a window so you will actually need one to receive window messages. But you can run a message queue in a thread that has no windows in it and handle process/thread messages (which aren't directed towards any particular window).

You can associate a hidden window with a service.

Hi
Is it possible to associate a hidden window with a service, moreover it is generally advised not to write interactive services (which have windows) and not use MFC support for windows services. So, how do I proceed?
Thanx
|
|
|
|
|
true... interactive services are become less viable in the newer versions of windows.
So, to have some sort of UI that controls your service, you'll could write a 2nd program which interacts with the service and serves as it's UI. You can use FindWindow to get the window to post messages to. There are other ways to communicate with a service that doesn't involve a window -- named pipes, tcp, mailslots, stuff like that.

Hi, I have a application and I would like to command lien pass parameters to it. But in other exe this command line parameter is null.
STARTUPINFO SI;
PROCESS_INFORMATION PI;
SI.cb = sizeof(STARTUPINFOW);
SI.lpReserved = NULL;
SI.lpDesktop = NULL;
SI.lpTitle = NULL;
SI.dwX = CW_USEDEFAULT;
SI.dwY = CW_USEDEFAULT;
SI.dwXSize = CW_USEDEFAULT;
SI.dwYSize = CW_USEDEFAULT;
SI.dwXCountChars = 0;
SI.dwYCountChars = 0;
SI.dwFillAttribute = 0;
SI.dwFlags = STARTF_USESHOWWINDOW;
SI.wShowWindow = SW_SHOWNORMAL;
SI.cbReserved2 = 0;
SI.lpReserved2 = NULL;
SI.hStdInput = 0;
SI.hStdOutput = 0;
SI.hStdError = 0;
CString sCmdLin = " UserID";
BOOL bRet = CreateProcess( m_sProductPath+"\\B.exe",
sCmdLin,
NULL,
NULL,
FALSE,
0,
NULL,
NULL,
&SI,
&PI);
After changing sCmdLin parameter to sCmdLin = "UserID" OR sCmdLin = " /UserID". But still i m unable to get the command line parameter in process B.exe. Pls suggest.
Thanks
SNI

Possibly you've to pass "B.exe UserID" as second parameter.

First, note that the CreateProcess() lpCommandLine parameter is an inout
parameter in the Unicode version, so whatever you pass a pointer to technically
needs to be writable (up to 32,768 characters). If that's not feasible, you should
instead append the commandline to the lpApplicationName parameter string and pass NULL
as the lpCommandLine parameter.
Second, if you're not getting the passed commandline parameter(s) in the spawned app,
try starting the commandline parameter string with whitespace.

Read this[^].
It is quite similar to what I always do when developing solutions for serial communication.
