Determine bounding rect of a string [modified]

Hey,

I've a string including multiple lines. Now I want to use the DrawText DT_CALC feature to calc the height of the bounding rectangle, but leave the right side as it is.

The returning rect has always a extended right side. How can I solve this problem?

Thank you...

<br />
CRect reRect(0,0,150,0);<br />
CString szText("Hallo\ndies ist ein Test\nHello\nthis is a test");<br />
pDC->DrawText(szText,&reRect, DT_CALCRECT);<br />

I don't what you are trying to do but does GetTextExtent[^] help ?

Maybe you should include DT_WORDBREAK flags?

pDC->DrawText(szText, reRect, DT_CALCRECT | DT_WORDBREAK);

Linker Error when compiling C++ project in G++ compiler

Hi,

This is my first post in the List.

I'm trying to compile a C++ code that uses AxisCpp on Windows
I get the following error:
[Linker error] undefined reference to `axiscpp::Stub::Stub(char const*, axiscpp::AXIS_PROTOCOL_TYPE)'

I have included the necessary libraries (axis_client.lib,axis_server.lib) and also mentioned where to look for the axiscpp header files.

I'm using Dev-Cpp 4.9.9.2 IDE for compiling. I have the axis package from http://ws.apache.org/axis (axiscpp for windows)
I'm unable to compile in Eclipse with CDT Plugin, also.

I'm able to compile the same using Visual Studio VC7.0 onwards.

Does anyone know a solution to this problem? (any extra linker options?)

Regards,
Sriram.V

Is it the compilation err or linker err?

Hi Sarath,

It's a linker error. I'm able to link all my other libraries except axiscpp libraries.

I'm having axis-c-1.6b for win32. The axis package provides 2 libraries "axis_client.lib" and "axis_server.lib".

The cl compiler that Visual Studio uses is able to find the libraries and I'm able to execute my project, but the g++ compiler that comes with Dev-Cpp and Eclipse with CDT plugin is unable to find the axis libraries.

One guess is that, the library I'm using is not conformant to the mingw compiler
or Does any extra linker arguments need to be specified for linking only axis libraries?

Getting Exception when two instance of ActiveX control are opened using Ctrl+N in IE

Hi,
I have developed a MFC ActiveX control and embeded it in IE. The control is working fine but when another instance of IE is opened using Ctrl+N, I am getting ASSERT exception in debug mode and in Release mode IE crashes.

Note that if the second instance is opened without using Ctrl+N (i.e by using explorer icon) no exception arrises.

what could be wrong. your support is highly appreciated.

Thanks

Hi,

In my application i need to generate an html page on-the-fly. The page is preseneted in the application's internal (iexplorer 6.0) browser.

Of course, i can generate a text file with all the html tags and all that is required, but i'm sure there's a more elegent way of doing so.

I couldn't find any on the web.

Does anybody have a lead?

Cheers in advance.

You can set the text directly to the brwser document right? I think most of the Dlls (e.g Team Track) generating HTML pages are doing in same way. Anyway for that purpose, you dont need to write to a file. Only need to keep that buffer generated.

Sarath is saying right. You do not have to generate a file. there is simple way.
You can get the interface IWebBrowser2 of the IE.
from that get the interface IHtmlDocument2 of the IWebBrowser2.

call the function write of the above interface.
IHtmlDocument2::write( "text" )

But this code will work onlt in COM

Hi,
An elegent way could be, have your data in xml format, write an xsl file that will transform your data from xml to html and display that html in webbrowser

Your can search for IDOMDocument interface for transformation of xml through xsl into html.

hope this satisfies you Cool | :cool:

Serialization

Hi all,

I have strange error during serialization. I do the following:

ar << m_nTime; // (Value typically > 120000)
ar << m_bFlag; // (type BOOL)

and the m_bFlag always returns as 0;

If I do the following:

ar << m_nTime;

int tmp;
tmp = m_bFlag ? 1 : 0;

ar << tmp;

everything works fine.

I'm certainly a little confused and if anyone has some ideas that would be great.

Thanks

Tom

it seems that you are trying to do this...

int tmp;
tmp = m_nTime ? 1 : 0; // depends on the time value you are setting flag
ar << tmp;</blockquote>

Im not sure whether i've answered you.
if you explain, what you are trying to do will be more useful.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
