I have an SDI MFC App, the CMainFrame has an in value that is to be displayed on the status bar
I have a OnUpdateWhat method with a CCmdUI * parameter the performs a test text using the value of the int
The value is modified from my CFormView member using the CMainFrame's public function modifyRecCount this function assigns the new value to the status bar value,
I am expecting to get the OnUpdateWhat called when the value of the status bar value field is changed but nothing happens...can anyone help?

Have you added ON_UPDATE_COMMAND_UI() to the message map? If so, have you set a breakpoint in the handler function to see if it's being called (which is only during idle processing)?

Yes, have added command in MESSAGE_MAP of MainFrame as
ON_UPDATE_COMMAND_UI(ID_INDICATOR_WHAT, OnUpdateWhat)
ID_INDICATOR_WHAT is the indicator for the Last panel on the right in the status bar
a break point in OnUpdateWhat is never hit

Have you added ID_INDICATOR_WHAT to the indicators array?

Yes
statuic UINT indicators[] =
{
ID_SEPARATOR,
ID_INICATOR_FNAME,
ID_INDICATOR_PROC,
ID_INDICATOR_WHAT
};
and in string table
ID_INDICATOR_WHAT 103

|

|

And you added a string resource named ID_INDICATOR_WHAT and gave it some value?
Do you see the pane in the status bar?
I just created a test SDI app and did nothing but the above and added the ID to the indicators array. Running the app showed 999 in the far-right pane. If you are not getting at least this far, all the rest is irrelevant.

Yes created a new project, and did all that was in the previous messages and
the what pane is initialized to 0,
Something interesting, I had code in the CMainFrame OnCreate function to resize the status bar width
for(int i=0;i<(sizeof(indicators)/sizeof(UINT));i++)
m_wndStatusBar.SetPaneInfo(i, ID_SEPARATOR, NULL, 100)
Removeing these line produced the initialize WHAT panel just like the test program...can you explain the order of event or why these lines coveted the panel

No, but I can ask two questions:
1) Why are you changing the ID of each pane to ID_SEPARATOR?
2) Why are you setting the pane's style to NULL?

Excellent questions, I suppose the id parameter should have been indicators[cnt] but is there a way to keep the style and not override it using this call?
Also, once the process inside the view is started, it makes a call to modifyRecCount in the CMainFrame class, this reassigns a new value to the int variable that is in the OnUpdateWhat code, however no update is seen and a break point added to the OnUpdateWhat does not occur

Even if you do something like resize the frame?

by the way if I haven't said it, thanks for the time,
Curious, cannot resize the frame, and if outside the debugger if I say, start it from a explorer window and press my run button, then touch the explorer window, a few seconds go by and the menu bar disappears but then I can resize the window again.. the symptoms tell me it is a control or messaging issue but I don't know where to look for the problem?

Hello Sir/Madam,
How do I implement arbitrary arithmetic precision in C Programming Language. By using only standard library.
Thanx in advance.

I googled before posting this qustion but i didn't find the appropriate answer.
So pls send the appropriate link.
|
|
|
|
|
there are links to at least five different libraries which do this, on the first page of that Google search.

Are you even serious? Do you expect someone to explain a possible solution to you in a forum reply like this? 
Just take a look at the GNU BigNum library if you need a library that implements it.

I don't need the libraries. I need a function and by using that function I wish to implement that one in my program without using any additional library which is not available in the standard template.
|
|
|
|
|
hey i mean with BY USING ONLY STANDARD LIBRARY is that use only header files those are available. Don't use any additional liraries.

Hey, that means you need to write it yourself!
|
|
|
|

1. You have to write it yourself.
2. From my understanding, this is a very daunting task and therefore there are very few successful implementations so far.
3. This forum is for asking specific queries, so you can do that yourself and come here to ask *specific* queries.

I don't have any clue dear that how I write a such type of function. So pls help me.

Can someone please help me with my bubblesort. It does not seem to sort and also prints 3 times.
#include <stdio.h>
#include <stdlib.h>
#include<time.h>
#define SIZE 6
#define MAX 53
void printArray(int N[], int T);
void fillArray(int N[], int T);
int main()
{
srand(time(NULL));
int PICKED[] = {0,0,0,0,0,0};
fillArray(PICKED, SIZE);
printArray(PICKED, SIZE);
return 0;
}
void fillArray(int N[], int T)
{
for(int P=0; P<T; P++)
{
N[P] = (int) (rand()% 52+1);
for(int y=0; y<P; y++)
{
if(N[y] == N[P])
{
N[P] = (int) (rand()%52 +1);
P=-1;
}
}
}
}
void printArray(int N[], int T)
{
for(int P=0; P<SIZE-1; P++)
{
if(N[P]>N[P+1])
{
int T = N[P+1];
N[P+1] = N[P];
N[P] = T;
printf("\nLOTTO PICKS\n");
for(int P=0; P<SIZE; P++)
{
printf("%d ", N[P]);
printf("\n");
}}}}

I suspect that P=-1 is not what you want.
