Well, looks good to me.
I suppose you have included iostream. It doesn't show since you haven't used the small < and > wonders below the text input frame when you posted your message.

Try this:
#include <sstream>
int main()
{
std::string Strings[] = { "a", "b", "c" };
std::ostringstream stm;
stm << Strings[2] << Strings[0] << Strings[1] << std::endl;
std::cout << stm.str().c_str();
}You'll get "cab" written to cout.

Thanks Roger, I managed to make it work this way:
myString = a[0] + a[1];

How do I create a UI thread capable of showing CDialog? I'm currently using AfxBeginThread for my working thread but also want to be able to display things like CDialog.DoModal from inside the worker thread. Do I have to make it a UI thread? How do I go about it?

The second version wants a subclassed CWinThread, but I'm not sure where exactly to place my code in it. May be in InitInstance. Any suggestions?
I already have the worker thread and the code for it, I need to know what to change to make showing modal CDialogs possible.

The second link shows common CWinThread overrides
and what those overrides should do.

Hi.I'm using visual c++ 9.0.
I want to do something like this:
string name = get_name();
string filename = name+("text.dat");
ifstream infile_file;
infile_file.open(filename);
(code)
(...)
I'm doing something wrong... or I am missing something.
Here is the error:
error C2664: 'void std::basic_ifstream<_Elem,_Traits>::open(const wchar_t *,std::ios_base::openmode,int)' : cannot convert parameter 1 from 'std::string' to 'const wchar_t *'
with
[
_Elem=char,
_Traits=std::char_traits<char>
]
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
Thanks.

this is because you're building your appblication in UNICODE most probably...
try removing the declaration of that macro and rebuild.
forget that. std::string::c_str() is the way to go

If the xlsx file is an XML file then probably not.
Do you have a C++ or MFC question?

The code base i use is MFC, with a class that get the Data from the xls Excel format over the MFC classes CDaoDatabase and CDaoRecordset.
I wrote this some times ago. Now i need to handle the new format of xlsx files.
I thought that xlsx is always XML, but i´ve now opend the xlsx file with a hex editor and it seems to be a bin file.
I need a hint or a solution how i can get data from the xlsx file over MFC or Visual C++.
regards,
andy

You won't get any WM_MOUSEMOVE messages in your dialog if you've set
capture to another window.
