I was trying to create a utility that would tell me what configuration an exe was built in. But as you say its just a set of compiler options. I understand it now. Thanks for explaining. I have a lot more questions but ill save it for another time.

Dear all,
I have problem.
What kind of dll that can store some functions and variables, and register it to windows runtime?
So that, I can execute (install) that dll from Windows Explorer and when I want store a value, say it name, I just write on my program:
data.name
without any declaration of Class Data.
And if I have a function in that class, say it write, I just write on my program :
data.write
Furthermore, write function will get value from variable name with another variables.
Please help me...
Thanks b4,
Eka Candra

A C++ DLL, exporting classes. Visual Studio's Application Wizard may build the DLL skeleton for you.

Only COM DLLs need registration.

I work not alone, but in a team work.
My team partner have already made an application some time ago.
He just made about user interface (front end application). He didn't know how our system work. He ever get some dll file from other person outside my team. That dll can executed and he can call variable inside dll without any declaration variable.
For description:
We want make a database system. My friend just make a front end application. For example, storing name, age, and address. On his program, he only call:
data.name = Eka;
data.age = 25;
data.address = somewhere;
and if he want to store that data to database server, he only call:
data.write;
without know how storing data to server happen and without passing any variable to the function.
All those variable and function are include inside dll file.
Can you understand what I mean?
I don't have any clue for searching on this forum or another programming forum.
So, please help me..
Thank a lot...

Why don't you have a look at DLL skeleton generated by Application Wizard. If it doesn't fit your needs, you may choose to build a COM compopnent.
BTW why don't you use ADO, that already exposes an object model?

I'm so sorry, I'm not expert in C or Visual C++.
What Dll type that you mean? As I know, if I used Win32 DLL, I can only passing some variable for a function, not temporary store them before the function is called. May I can used global variable for storing value, but how can I store directly to global variable inside DLL from outside DLL file?

Thanks for your suggestion, I will learn about COM component. I never used it and I also never know about it before.

No, that is just an example to descripting how dll type that I mean.
Thanks a lot for your suggestions.
I will try about COM.

Hello All,
I have used the List Control in Win32, same i want to implement in MFC, i am unable to do that can anyone help me with this.
Extracting the contents of the list Box in Win 32.
HWND hList = GetDlgItem(hwnd, IDC_FLIST);
int count = SendMessage(hList, LB_GETCOUNT, 0, 0);
for ( int i=0; i < count ; i++ )
{
int itemTextLen = SendMessage(hList, LB_GETTEXTLEN, i, 0);
char *itemText = new char[itemTextLen];
SendMessage(hList, LB_GETTEXT, i, (LPARAM)itemText);
}
MFC:-
int ListSize;
ListSize = m_WLinks.GetCount();
for(int i=0;i<=ListSize;i++)
{
}
In Win32 i had handle so got the control of the list box but how to do that in MFC ?
Thanking you,
Naveen HS.

good morning
in MFC what you can do is
define a member in your mydialog.h
CListBox m_MyListBox;
use DDX to link you member with the control.
DDX_Control(pDX, IDC_MYLIST_BOX, m_MyListBox)
Then to read the content
CString sText;
int ListSize = m_WLinks.GetCount();
for(int i=0; i!=ListSize; ++i)
{
m_MyListBox.GetText(iIndex, sText);
}
Regards
Franck

I created WGI, a GUI lib written with C. WGI is open source. I issue the demo project of WGI 1.0.0. Here to download its source code: http://code.google.com/p/oic-wgi/downloads/list
What WGI? WGI is doing what MFC has done, to encapsulate API, BUT WGI uses OIOIC, instead of C++.
Look forward to various advices sincerely.

Hi...
I am having a CString variable like
str = "Hi this is circle then it needs ro circle jsdfhd circle hjdfhdgf circle ysdfh circle feduf";
Now i have to find how many same("circle") words repeated in the string.
How can i find?Help me.
Thanks...

You can use the Find method of the CString class in a loop by adjusting its iStart parameter.
|
|
|
|
|
I used Find method. But not get. can you please tell me something brief?
G.Paulraj

Create an integer variable iStart and set it to 0.
Call str.Find("circle", iStart);
Check the return value.
If it is -1, the word was not found.
Otherwise use str.Mid with the return value from Find as the first parameter.
Now increment iStart by the 6, which is the length of the word "circle".
Repeat the loop till Find returns -1.
It is recommended to enclose all strings in the _T("") macro so that it works for both UNICODE and NON-UNICODE builds.

Hope you tried your hand before getting the code.
CString csStr = _T( "Hello it is circle, how is this circle" );
LPCTSTR CIRCLE = _T( "Circle" );
int nPos = 0;
int nCountCircle = 0;
while( -1 != ( nPos = csStr.Find( CIRCLE, nPos ))
{
nPos++;
nCountCircle++;
}
Величие не Бога может быть недооценена.

Could it will like this, possibly instead of nPos++ to nPos+= _tcslen(CIRCLE); , little more performance oriented code

The cheeky method:
Make a copy of the string and run CString::Replace() on it. It will return the number of replaced instances.

It's probably a 3-state button which remains pressed when it is clicked once and is released on the second click.
|
|
|
|
|
as you say it's a 3-state button ,it's a button in toolbar but i cann't understand how to update view in a dialog control
