what do u mean by EXPORT TABLE how do i use that
A DLL's export table is the list of functions that it exports. Read about it in more detail on MSDN.

The export table in the DLL lists all the functions that the DLL exports. This is what the DEPENDS tool examines, so you can't get more than what DEPENDS gives you. It doesn't give parameters or return type.

Hi,
I want to start the same routine which runs if I press the searchbutton when I press enter on my keyboard. I think that I can realize that with the function OnChar(UINT nChar, UNINT nRepCnt, UINT nFlags) but it doesn't work.
OnChar(UINT nChar, UNINT nRepCnt, UINT nFlags)
{
if(nChar ==VK_RETURN)
{
OnSearch();
}
}
Please give me a tip if you know something. I am a beginner.

You should override PretranslateMessage of view/dialog
If you button is focused and < Enter > is pressed, call your routine.

Hello all
I wonder, does anyone knows the limit for of threads that the Os is allowing for one application to open ?
10x'
|
|
|
|
|
I believe you can have as many threads as the memory and CPU can tolerate. I once had more than 100 threads in a single test application running on Windows NT 4.0. But if you have too many threads, some of them will starve (not gettting any share of CPU to do anything) and the memory usage goes up quickly.

The practical limit is far below the physical limit. (Except in rare cases, I question using more than a few dozen threads and for the exceptions, more than a few hundred [and for those few cases, the code could, and should, have been rewritten to use I/O Completion ports].)

or if i had CString mystring = "55545"

write an own algorithm, it's the easiest way i think
Don't try it, just do it!
|
|
|
|

in <ctype.h> (CRT) look for the functions :
::isalpha
::isalnum
::isdigit
::isxdigit
|
|
|
|
|
bool containsAlphaCharacters(CString str)
{
str.MakeLower();
return(str.FindOneOf(_T("abcdefghijklmnopqrstuvwxyz")) >= 0);
} or
#include <ctype.h>
bool containsAlphaCharacters(CString str)
{
for(int i=0; i<str.GetLength(); i++)
{
if(_istalpha(str[i]))
return true;
}
return false;
} Hope this helps,

cheers ryan,
nice one

You're welcome
If you feel up to it, do a bit of a speed comparison and let me know which one is quicker . They're probably about the same, but the first one will probably be slightly slower.

halo,
I have a application which has two list box and my plan is that i must retrieve the data in the list box and somehow save it (perhaps in a integer variable) and if the data in both the liat boxes are same then there must be a error message displayed.. I tried out the following:
void Cdlg3Dlg::OnCamdone()
{
int i=0;
CListBox* m_ptele;
CListBox* m_pls1;
if (m_ptele->GetItemData(i)==m_pls1->GetItemData(i))
{ AfxMessageBox("Both boxes have same data");
}
}
but when i run the program i get the microsoft error box problem:
The xxxxxx application has encountered a problem and needs to close. We are sorry for the inconvenience. If you were in the middle......and so on.
i want to know whether it is the problem with my program..and if it is so can someone help me out.
Thanks,
Deepak Samuel

read LB_GETITEMDATA in msdn... it's the wrong function u chose!
use GetText member function!
Don't try it, just do it!
|
|
|
|
|
One solution is GetItemText() as the other member has mentioned.

Hi,
I would like to know if I can add few methods to class Clist.

create a class derived from CList and put your methods there...

i want to share the member variables and function between the various classes.what all methods can i use to achieve it?also, how do i use a friend function ?
Every problem has a solution!
|
|

|

lol, i think this is a lama question for an it student, if your really one...
describe your situation a bit better... i dont really understand what your problem is
p.s. description for friend function-> see msdn
Don't try it, just do it!

Actually i am making a program for a cnc machine. I have made various classes and i wished that what all info i entered in the dialog box, should be depicted in view.
Unfortunately, the view is executed even before i enter values in the dialog box.
is there any method by which i cud add a kind of delay to prevent the execution of view until i press ok.
when i wrote the code for OnOk it didn't call the ondraw function from there so i thought i shud use a friend function . i know how to use a friend function but as i am new to VC++ i wanted to know if some special method is used.
I don't have MSDN library so thats where the problem is coming and YES i am an IT student.
Every problem has a solution!

do u launch the view in a different thread??
normally a DialogBox function is a blocking call
Don't try it, just do it!

I'm receiving a string of characters over a socket connection. I know that the string is of a number of fields that are a fixed length. How can I break up this string where each fixed length field goes into it's own member variable?
Being a cobol programmer too, in cobol we can just move it into a structure where the structure is set with all the fields and their fixed lengths. Can I do this in VC also?
Thanks

if your string was called "strings" and it is comprised of integers you could to this...
<br />
int temp0 = strings.at(0);<br />
int temp1 = strings.at(1);<br />

cin >> knowledge;
