Check
this[^] class its quite worthy
As for the rest you just have to read the file, send it on serial and then read it on the other PC then write it to disk.

Hi,
I have an MDI application whose main frame will receive a message which should be sent to the correct view..With this message i will be having an Object ID(i.e. One of my child window has some object on which i have clicked..the ID of that object is sent to a second application which Sends a message back to the first application with ID).So is there any way i can identify the correct view with the help of this Object ID???????
Plz reply
Thanx in advance

From the main frame, get the document to iterarate round all the current views (CDocument::GetFirstViewPosition & CDocument::GetNextView. Add a OwnsObject function to each view, and call it for each view. In that function, have the view check to see if it owns the supplied object ID.

Hi
I am creating an ATL Composite Control which contains WebBrowser control.I have created this using CAxWindow::CreateControl and CAxWindow::QueryControl and got the IWebBrowser2 Interface.
How can i handle events for this Browser Control? I have to get all the PopUps coming from this window and have to route this to my own windows, not in the internet explorer.
Thanks

Hi
Could someone tell me how I can debug STL types easily in VC++ 6? Everytime I use e.g. vector I can never see its content in the debug window.
Thanks!

Add this:
std::basic_string<*>=<c_str(), st>
std::vector<*>=size=<size(), i>, capacity=<capacity(), i>
std::map<*>=size=<_Mysize, i>
std::set<*>=size=<_Mysize, i>
std::list<*>=size=<size(), i>
std::deque<*>=size=<size(), i>
std::pair<*>=first=<first>, second=<second>
std::list<*>::iterator=val=<_Ptr->_Myval>
std::list<*>::const_iterator=val=<_Ptr->_Myval>
std::_Tree<*>::iterator=val=<_Ptr->_Myval>
std::_Tree<*>::const_iterator=val=<_Ptr->_Myval>
To VSDir\Common\MSDev98\Bin\Autoexp.dat
That will give you some more info on the stl types. To actually see the contents of a vector, say called m_vec, you can actually take the address of the first element to be equal to the address of an standard C array stored in the vector - say &m_vec[0]; This is because STL gaurentees that the vector occupies contigous memory.
If m_vec was a vector of ints (and your using STL port), you can do this:
((int*)&m_vec[0]), 100 to expand 100 elements in the vector in the watch window.
Unfortunatly, standard stl wont let u call [] operator in the watch window. You can do
((int*)&(*m_vec.begin())), 100
If you can remeber all that lol

There are methods of injecting code to a running application. But is there any method to remove such injected code without crashing the host application?
For example, the SmileyCentral program MWSOEMON.EXE injects a toolbar into MSN messenger. If we kill this process, MSN messenger crashes. Is there a way to remove the toolbar and terminate MWSOEMON.EXE?
|
|
|
|

Depends on what technique you used to inject the code; whether you know at what points during the host's execution the injected code will be called. Difficult to predict such behaviour though!
As far as I recollect, MWSOEMON is spyware.
For removing the toolbar from MSN Msgr, I'm sure there must be a better way. Havent yet tried it, but I'm sure there must be!

Hi.
I retrieve a value from the registry and it is a dword. I want to display it in a text box and I also want to store it in a interger? How can I do that?
Thank you very much in advance!
Well... I am a beginner ...
|

Maybe you can cast it?
int an_int = static_cast<int>(a_dword);
In VC++, you can display the value of an int like this:
CString str;
str.format("%d", an_int);
MessageBox(str);
This may not be the optimal solution though... my Microsoft-specific programming knowledge is seriously lacking.
|
|
|
|
|
CString str;
str.Format("%i", YOURDWORD);
yourtextbox.SetWindowText(str);
I thing you can just cast it:
int yourint;
yourint = (int)YOURDWORD;
or
yourint = static_cast<int>(YOURDWORD);
should be something like this.

Hi,
Could you help me?
How to find lenght of any string in MFC.
rajesh
|
|
|
|
|
Depends of the type of the container
CString str = "Hello";
str.GetLenght();
char *pcHello = "Hello";
strlen(pcHello);
Check also:
wcslen
_mbslen
_mbstrlen
....

CString str = "Any string ";
int len = str.GetLength();
len will return u zero based length
Also chk CString class in MSDN..
|
|
|
|
|
Another method would be.
CString a;
i=0;
do
{
if(a.GetAt(i)=='\0') return i;
i++;
}
The easiest way is CString.GetLength()
|
|
|
|
|
If a has more than one \0 character, your method would not work.

And why wouldnt it?
Bikram Singh

Because the return statement gets executed at the first \0 character. A CString object can contain more than one \0 character.

Yes, but when one says "string length", it does not include null characters. assuming ofcourse, the discussion related to ansi chars.
btw, really really nice signature !! ha ha !!!

"String" and "null-terminated string" are not the same thing. A string can have a length in bytes as well as a length in characters. Assuming ANSI is a habit long since broken.
