How is this working with only a single backslash?

Hi friends,
I have unicode string like
wstring filename = "??????? ?????, ????? ? ª ????";
which I am trying to convert to normal multibyte string using
WideCharToMultiByte API.
But the conversion fails. Please refer Following code
int Length ;
// Here I call this API to get length of the wstring
char* output = new char[Length];
int foundUnmapable = FALSE;
My call is like
WideCharToMultiByte(CP_ACP,
NULL,
input.c_str(),
-1,
output,
len,
NULL,
&foundUnmapable );
This code fails saying that foundUnmapable = TRUE;
GetLastError() return 1008 error number which means
"An attempt was made to reference a token that does not exist."
Can anybody point out the issue here?

One correction
wstring filename = "??????? ?????, ????? ? ª ????";
Which is actually string of special characters. But I am unable to post those chars in this web page. It automatically gets converted to "????..."

|
|
What type of input vriable "input" which you used as 3 argument in WideCharToMultiByte and what is the value of 6 argument len ?
|
|
|
|
|
sorry for mistakes. I actually wrote code here.
// Please assume that
input = filename.
and I am using WideCharToMultiByte API to get length.
Please do not look at syntex errors out here.
The main issue is
I have wstring which contains special characters.
I am trying to convert this wstring to mutibyte string using API
WideCharToMultiByte with code page "CP_ACP"
And it fails.
Note: I dont know how to paste those special chars here for your reference.

If you are using WideCharToMultiByte to get length then pass NULL as 5th argument and 0 as 6th argument. It will return length.
|
|
|
|
|
I already said that I have working code at my place.
I know how to get length and other things.
Please see my earlier posting for exact question.

from WideCharToMultiByte reference [^]
lpUsedDefaultChar
[in] Points to a flag that indicates whether a default character was used. The flag is set to TRUE if one or more wide characters in the source string cannot be represented in the specified code page. Otherwise, the flag is set to FALSE. This parameter may be NULL. The function is faster when both lpDefaultChar and lpUsedDefaultChar are NULL.

How do you know it fails?

I got the point.
I have such file name with speical chars.
But when I replace all these chars using say 's'. File opening fails.

LONG TabbedTextOut(<br />
HDC hDC,
int X,
int Y,
LPCTSTR lpString,
int nCount,
int nTabPositions,
CONST LPINT lpnTabStopPositions,
int nTabOrigin
);
I thought the number of tabs and the positions of tabs are determined by the "\t"s contained in lpString, but it does not turn out to be that simple.
What is TabbedTextOut's behavior if the number of "\t"s does not equal nTabPositons?
I simiply thought that TabbedTextOut would simply replace those "\t"s in lpString with blanks and the last three parameters did not make any sense.
But the fact is the width positions of these "\t"s are depent on the last three parameters.
How do these three parameters work?
thank you.

True, the position of the tabs are determined by the values in the 7th argument to TabbedTextOut() (e.g., lpnTabStopPositions).

Aren't the comments in your code snippet sufficient?

I think by interpreting lpString, TabbedTextOut itself can figure out how many "\t"s there are and thus the sixth parameter nTabPositions and the seventh lpnTabStopPositions, which together indicate the number and the positions of the tabs in lpString, do not make any sense.
Besides,
for example, when I call TabbedTextOut the following way,
<br />
int nTabStopPositions[] = { 105,110,120 };<br />
TabbedTextOut(hdc, 100, 100, <br />
"aaa\tbbb\tccc",<br />
11, 3, nTabStopPositions, 50);<br />
Supposing the map mode is MM_TEXT,and the char width is 5.
TabbedTextOut will draw the string where it is 100 pixels to the left and 100 pixels to the top of the client area, breaking the string with tabs at 100+3*5 and 100+6*5+8( a tab equals 8 blanks ).
This is the way I think how TabbedTextOut works, but it seems not working that way.
Thus I don't understand how the last three parameters work.
thank you

Hello boys.
I discovered a thing that leaves me upset...
I compiled a C-"Hello World" and a C++"Hello world" using MS VC++ 2008 Express edition default release settings and
I noticed that, inspecting files with "Dependencies Walker",
both of them depend on some kind of "Runtime Libraries".
They are MSVC90R.DLL for pure C EXE and MSVC90R.DLL plus
MSCVP90DLL for C++ EXE.
I compiled the same sources with gcc/g++ compilers and, of course, there are no dependencies on external DLL.
I compiled the sourcers with my old VC++ compiler (Visual Studio 6, professional edition) and, again, I found
no dependencies on external DLL.
So
1) Why Ms decided to make EXE files DLL-dependent as default setting? Shouldn't C/C++ produce an executable the
most library-free as it can?
2) How can I avoid this? As I expect I CAN produce an executable which doesn't need VC2008 runtime libraries...can't I?

By default (I think since VS2003) projects are now linked with the dynamic library version of the runtime library. However you can change such setting:
Select Project->Porperties menu item, then Configuration Properties->C/C++->Code Generation node in the newly appeared window and finally change the Runtime Library value (from Multi-threaded DLL (/MD)) to Multi-Threaded (/MT).

MS's opinion is that it's better for apps to use the DLL version of the CRT. It means less memory usage when multiple apps are running, because only one copy of the DLL has to be loaded. It also means the apps will automagically pick up updates when the CRT DLLs are updated.

Yeah, but also means that a simple "Hello World" program needs a cortège of DLLs in order to work...
And I suppose this also means that any function call I performs whieghts twice as it could, as there is an interpreter library between my EXE and processor directives....
I mean, if I need a high performance executable, with a lot of calculations and functions calls (whose simulation lasts about one hour or so), isn't this external DLL linkage very taxing?

On my program, I need to import file in format:
- AI (adobe illustrator)
- CDR (corel draw)
Someboby know a library (free or commercial) to import/export this file?
Thanks.

Open source, maybe INKSCAPE[^]

Inkscape open only Adobe Illustrator SVG file, not ".ai" files

Never mind the reply I just deleted...apparently the AI file format is published
publicly

Yes, you are right ... but
1) AI file format is public only for version 10 or down, for the new CS versions the internal code is PDF.
2) I think it is better to use a library instead of write my own the code, no?
|
|
|
|

1) oh bummer
2) I'd agree there. I looked into Adobe compatiblity in the past and it
was difficult to get the specs. I imagine that makes it difficult to write
libraries too.
It doesn't look like the Adobe Partners program gives out too much info either.
If I come across something I'll definitely let you know.
