Hi,
I am using VC+ 7.0, how can i add an image in dialogbox(MFC Dialog based appln) which will appear in starting of the application as background for that window. How can we add controls on that window.
Thank you........

There are couple of ways , doing this easiest way is to just use Picture control , availabe in control toolbar , other solutions might to use statndard GDI Api's such as BitBlt m StrtchBlt for reference u can visit Bitmap section of codeproject.

hello there ..
there is a slight problem that i am facing with strings greater then 32k
i have a variant bstr containing a string which is greater then 32ks..
1. how do i store this thing? into a buffer?, but then how do i get the size of the bstr string so that i can create a buf of that size?
2. how do i truncate this bstr string into strings of sizes 32ks?
thanks for the time
regards

Why are you wanting to store something that is already stored? If the bstr variable already holds the data, why are you wanting to create another variable to hold that same data?

Something like this, maybe:
BSTR b = SysAllocString(_T("This is a 32k string"));
TCHAR left[11],
right[11];
_tcsncpy(left, b, 10);
left[10] = '\0';
_tcsncpy(right, b + 10, 10);
right[10] = '\0';

Curious, does anyone have a link to how to make a simple Single Document Application Database using mfc? After doing some reading I see that I use CObject and CArchive however I'm kinda clueless of what to do from there. A good commented example would be great. All i want to do is have a form view to fill in a few edit boxes then it search the database (file i make) and spit out the results.
Thanks,
Ps. Anything other than the msdn site will get great the msdn site seems to far fetched.

This isn't going to be an MFC "purist's" response.
These steps are simply the simplest ways to get a database thing going.
They do not rely on the App Wizard to do anything. They do not tie member variables to data fields.
To access a database that has an ODBC mapping to it, do the following:
1) #include <afxdb.h> in your source file
2) To pull records from your database, do the following:
<br />
CDatabase db;<br />
db.OpenEx("XXX-ODBC DATASOURCE MAPPING NAME GOES HERE-XXX");<br />
CRecordset rs(&db);<br />
CString QueryString;<br />
CString data;
<br />
QueryString = "SELECT * FROM tablename";
<br />
rs.Open(AFX_DB_USE_DEFAULT_TYPE, QueryString);<br />
<br />
while(! rs.IsEOF())<br />
{<br />
rs.GetFieldValue("FieldName", data);
rs.MoveNext();
<br />
}<br />
<br />
rs.Close();<br />
db.Close();<br />

i want to make my own multi-thread socket classes (really really simple ones, so i can use them in my small games and such, and just to learn)
i want to create a thread that will call select() and will allow for me to wait for feedback on a set of sockets
however, i want to interrupt select() so that i can add sockets to the select list when the user calls AddSocket()
how would i do that? i dont want to forcefully end the thread, nor do i want to create a thread per-socket
hmm?

Well, I don't think you can interrupt select. But, if you want to start a thread to respond to socket events on a set of sockets, you may consider calling WSAEventSelect instead. Associate an event handle with each socket, register for events you are interested in with WSAEventSelect for each socket, then to wait for the events, call WSAWaitFormultipleEvents. The thing about this is that the array of event handles can include other events besides socket events. So, maybe the 0th event handle could be an event that another thread could use to signal the thread that is waiting for the sockets to do something else, like shutdown, or whatever else.

I'm trying to use this function, but my debugger doesn't recognize it. Is there something I need to define or add to my stdafx? Or, is there a better way to find out the name of the SQL server if it isn't local?

Are you getting a compiler, linker, or runtime error? If it's a compiler error, be sure to include Sqlfront.h and Sqldb.h. If it's a linker error, be sure to link with Ntwdblib.lib.

Thanks, that did seem to work. The sweet irony is, though, that the Sqlfront.h has a compiler error itself:
Compiling...
testLibraryDlg.cpp
c:\program files\microsoft visual studio\vc98\include\sqlfront.h(126) : error C2146: syntax error : missing ';' before identifier 'LPINT'
c:\program files\microsoft visual studio\vc98\include\sqlfront.h(126) : error C2040: 'PTR' : 'int' differs in levels of indirection from 'void *'
c:\program files\microsoft visual studio\vc98\include\sqlfront.h(126) : fatal error C1004: unexpected end of file found
Error executing cl.exe.
I'm trying to use SQLBrowseConnect to connect to an unknown server name now, but I'm having even less luck with that. I cut and pasted the example in the MSDN help, but it's got it's own compile errors.

Try moving #include <sqlfront.h> down a few lines (i.e., so that windows.h is included first).

Thank for responding. Somehow, I got SQLBrowseConnect to work for me, so that serves the purpose I needed. Thanks, though.

You don't remember what you did to squelch the errors with sqlfront.h?

No, I never figured it out. I just gave up and moved on to a different function. It took me a while, but I got SQLBrowseServer to work for me.

I have an application where I create modeless dialogs. I want to remove the X (Cancel) symbol on the title bar. I have tried removing it with the properties for the dialog, but that doesnt seem to work. I have many dialogs and need to be able to move them around, etc. Can I use a graphics editor to remove the symbol? Can someone tell me how I might remove it.
Thanks.

When you call the window's Create function, try looking at the various styles. I can't remember off the top of my head, but I'm pretty sure there's one that specifies whether or not there should be a Close button.
