thank you i will try.......

Its working well except CStringArray that is...........
1 void SRecordset::Serialize(CArchive& ar)
2 {
3 if (ar.IsStoring())
4 { // storing code
5 ar << iNumFldCount;
6 ar << iNumRec;
7 ar << iTotalSize;
8 ar << saDataContainer;
9 }
10 else
11 { // loading code
12 ar >> iNumFldCount;
13 ar >> iNumRec;
14 ar >> iTotalSize;
15 ar >> saDataContainer;
16 }
17 }
Above the code will be thrown error during the compilation that is error C2678: binary '<<' : no operator found which takes a left-hand operand of type 'CArchive' (or there is no acceptable conversion) at LINE NO:8
saDataContainer is a CStringArray variable how can i write it.....
what can i do please help me

CStringArray has its own Serialize method. You only do call CStringArray::Serialize and it will do the job for you.
void SRecordset::Serialize(CArchive& ar)
{
if (ar.IsStoring())
{
ar << iNumFldCount;
ar << iNumRec;
ar << iTotalSize;
}
else
{
ar >> iNumFldCount;
ar >> iNumRec;
ar >> iTotalSize;
}
saDataContainer.Serialize(ar);
}

how to dynamic display the value of mouse's coordinate during the mouse moving

Within your application window or globally? However, check GetCursorPos()

how do i set a draggable marker in My editor with CRicheditview as base class

There are many ways of doing it. Some easier than others, it all depends on what you want. If all you want is a line drawn from top to bottom then what I would try is using a borderless, one pixel wide child window that sits on top of the view. If you want anything more complicated then you will have to start drawing the view yourself, not a simple task.
It's not rocket surgery!
Within you lies the power for good, use it!!!

Hi,
I want to use methods in an activex component (.ocx) file in C++;
In VB I simply used Set obj=CreateObject("MSScriptControl.ScriptControl")
I don't know how should I do the same (either LateBonding or EralyBonding) in C++.
I'd be glad if someone could help me out!

hi once again... tnx for the answers to my previous posts...
again i have another qxn to ask...
will the code below post any memory leak or any pointer problems?
i am unsure as how to write the code for a struct to have an indefinite size of array of structs inside it. so what i did is to just use a pointer and have a member which holds the size of the array pointed to. is there any efficient way to go about this? tnx a lot!
typedef struct
{
int number;
int number2;
} TEST, *LPTEST;
typedef struct
{
LPTEST pTest;
int number;
} TEST_CONT;
TEST test[2];
test[0].number = 123;
test[0].number2 = 45;
test[1].number = 678;
test[1].number2 = 910;
TEST_CONT testC;
testC.pTest = test;
testC.number = 98765;
int n = testC.pTest[0].number;
int n2 = testC.pTest[0].number2;
cout << n << " " << n2 << " " << testC.number << endl;
n = testC.pTest[1].number;
n2 = testC.pTest[1].number2;
cout << n << " " << n2 << " " << testC.number << endl;

No memory leak in the code just because there is no object created by 'new'.
TEST_CONT testC;
testC.pTest = test;
testC.number = 98765;
here testC.number should be the number of elements of the test, right? So why 98765?
C++ provides std::vector class which is a dynamically growing array. You might use it like so;
typedef struct
{
std::vector<test> tests;
} TEST_CONT;
TEST_CONT testC;
testC.tests.push_back(test);
//...
int n = testC.tests[0].number;
int n2 = testC.tests[0].number2;
cout << n << " " << n2 << " " << testC.tests.size()<< endl;

hi Arman! tnx for the reply.
oooppss... yes that should be the count... i had that in mind but when i was trying out the code didnt really put it in the implementation...
tnx for the suggestion regarding vector... i'll consider it.
again tnx!

Hi,
I have a Byte buffer. I need to keep on appending buffers to my initial buffer. How to do it?Any suggestions would be helpful.
Thanks
Today is a gift, that's why it is called the present.

Why not;
CByteArray array;
array.Add( myByteValue );

It depends on the language used, but seeing as this is mainly a C++ forum.
The STL provides the ‘vector’ class for creating dynamic buffers.
The MFC provides different containers for doing the same thing, including CByteArray.
If you where writing it in C, then you would have to create your own method for doing the same thing. Usually dependant on a structure pointer (or handle), if done right, that is passed to the required functions.

Is PostQuitMessage of any help?
|
|

|

If all your application does it play a sound then exit why does it need a window at all?

Post a WM_CLOSE message to your main window.

1. Why Interlocked functions not have only-read operating funciton?
2.Interlocked function working at value A, at the same time other thread a function read value A, who first pass? If i want fist read operation then write operation, how to do?
3.example 1:
more thread1 run, but i want only and only run first thread1 can do (1) until ReWork function run. Can those code good work?
volatile LONG g_bLock = FALSE;<br />
<br />
VOID thread1()<br />
{<br />
if (!g_bLock)<br />
{<br />
InterlockedExchange(&g_bLock, TRUE);<br />
<br />
(1)<br />
}<br />
}<br />
<br />
VOID ReWork()<br />
{<br />
InterlockedExchange(&g_bLock, FALSE);<br />
}
Thanks.
