Hi Mike,
Thanks for for the detail explaination, in this case and as you suggested I will use COM instead off DLL from VB.net ... now I remember why COM is much more powerful to use through different platform & programs!
Many thanks

I have an MFC application that is built around the doc/view architecture. I have written some code to save the view's output to a jpg. We shell execute this program from client applications, but now I, or rather my boss, now wants us to use the doc/view code in a dll so that we can save the view's output to a file directly from a client application.
As an analogy imagine loading up a Scribble file in the scribble tutorial (but as a dll rather than an exe), from a simple win32 application. Once save the scribble code returns the result to the win32 app.
How easy is this to wrap the MFC classes in a dll that simply exports a "C" call to kick off the doc/view stuff load/save stuff and close and return the result to the caller, what do I need to do to kick off the MFC stuff properly?

Did anyone work with BOOST uBLAS library for linear algebra?
I want to create matrices and also apply some functions such as svd (Singular value decomposition), eig (Eigenvalues and eigenvectors), diag (Diagonal matrices and diagonals of a matrix) and pinv (Pseudoinverse).
I want to know that uBLAS can do these functions or not?

did you have a look at the standard Matrix class ?

Dear One,
I am working on MFC Dialog based applications.I have a problem that when i used the Main dialog class with a CCombo control over it I made a control type variable for it and it worked fine
BUT
When i made another new dialog class with some CCombo control with a variable of control type,It returned an assertion failure which is as follows:
File afxwin2.inl
Line:735
Please help me in this regard.For I have got very very short time to complete my project.Time line for it is one week left to complete this project.
Thanking you in Anticipation

Which means you are trying to add a string to a combobox that does not yet exist.

Remember that this is your project, not ours. Just because you have an emergency does not mean you get help any faster.

Hi David,
How r u?The problem is not that i have not added the combo box yet but is that when i made control variable for that combo box while debugging it showed me in the Quick watch
Variable Name: m_Categories.AddString("Asif Rogers");
Value:CXX0052: "Error:Member fuction not present"
So problem is with control type variables and not with Value type variables.
Thanx for your kind response

I can only offer what I see in the source files. Line 735 of afxwin2.inl looks like:
ASSERT(::IsWindow(m_hWnd)); return (int)::SendMessage(m_hWnd, CB_ADDSTRING, 0, (LPARAM)lpszString); Note there's only one assertion on that line.

hi..
this piece of code is from vc++.net
MessageBox(0, "Please Check Row No:" + j ,"Validations",MB_OK);
When i try to concatenate some text string with an integer value(j), it compiles successfully. but the output is confusing.. for example..if the value of j is 5, then it trim 5 chars from the left in hat text string..
SO i tried it with concat function...like this..
MessageBox(0, String::Concat("Please Check Row No:" , (Datagrid1->get_Item(j,0))) ,"Validations",MB_OK);
This returns error
"error C2665: 'System::String::Concat' : none of the 9 overloads can convert parameter 2 from type 'System::Object __gc *'"
Can anyone solve my problem?

Use CString object:
<br />
CString str;<br />
str.Format("Please Check Row No: %d Validations",j);<br />
MessageBox(0,str,MB_OK);<br />

Maetto..
Thanks for yr reply.. i tried this...
But it returns error "CString : Undeclared identifier."
i put this code in .cpp file...
should i have to include any header files here?

> CString str;

> But it returns error "CString : Undeclared identifier."
char szBuf[200];
sprintf(szBuf, "Please Check Row No: %d Validations", j);
MessageBox(0, szBuf, MB_OK);

Never go heavyweight when lightweight works fine:
TCHAR caBuffer[ 64 + 1 ];<br />
<br />
_snprintf( caBuffer, 64, "Please Check Row No: %d Validations", j );<br />
caBuffer[ 64 ] = '\0';<br />
MessageBox( NULL, "Example", caBuffer, MB_OK );
Peace!

CString is defined in "cstringt.h" (MFC) or "atlstr.h" (NON-MFC)

I have the following pb:
I have an simple MFC app where I launch a function(INIT) that starts a thread(THREAD 1=wait for connection) that connects to a socket(CSocket).After the connection,I Detach and get the handle...now...my pb is this:
if I re-Attach the handle of the socket after the connection in the INIT function then when my server "dies"...I get the OnClose event on the CSocket object...but if I try to re-Attach the handle of the socket inside that Thread 1 or even in another Thread 2...I never receive that notification of the OnClose event
Anyone knows why, and the most important...does he have a solution for this pb ?
(I admin that I'm a begginer with MFC)

Hi,
I have a binary string. I need to search certain characters.
I used to use "memstr" (obtain fist substring from string) on
Unix.
Is there anything similar to that available from MFC?
Thanks,
Kevin

If your are using CStrings, yes, CString::Find
~RaGE();
|
|
|

Use the CString to store the binary data
&
use Find (..) member fuction to find the charaters.

There is nothing exactly like memstr(...) in MFC or in the MS VC++ RTL. The closest things are strstr(...) and and functions like CString::Find(...) .
However, these might not work as you expect, because you said "binary string", and that usually means that NUL characters can be expected in other locations than the end of the string.
Other than taking an existing implementation and copying the source or writing your own implementation, a Q&D way would be to store the locations of all of the non-terminating NUL characters and convert them to some other character and then use a function like strstr(...) (with the strings modified as specified above).
After locating your substrings, you can convert them back by replacing the NUL s you replaced before.
Peace!
