sorry, i don't know of a way to automate the process, or to do it through the UI.
i suppose you could write an XSL transform to do this. i've written many simple XSLTs to manipulate vcproj files (to strip out unused configurations and to change paths, etc.). but this task is just a little bit beyond what i know how to do.

hello everybody,
Is there any way to get the notification of changes in taskbar.
E.g:
Any new window started to display in taskbar?
Any existing window closed in taskbar?
Any windows in taskbar is flashing in taskbar?
I need to get such notifications.
Help me please!

I personally don't know any specific way to do that, but if no such turns up you could try hooking into explorer.exe and find and subclass the tray somehow, using spy++ it seems that the taskbar is actually a toolbar, so you should be able to "capture" messages sent to it when new buttons are added or buttons are removed. Another aproach would be to install a global message hook and filter out messages targeted at the taskbar and do what you need with them (relay the events to your application or so...). I hope if nothing better appears then this can give you a starting point to do it...good luck.

I want to capture messages (WM_PAINT) to task bar in my application.
Please provide any help.

Give a bit more details about what exactly you are trying to do, please.

hai thanks for the reply.
Actually I want to filter WM_PAINT message of Taskbar as you mentioned in your first reply.
When WM_PAINT message is executed in taksbar, I want to get that message in my application.
May be subclassing may help to do it. Let me check that.

I hope someone has seen this tutorial ?
This is from the quiz at the end of the first chapter.
question 13)
The moon’s gravity is about 17 percent that of Earth’s. Write a program that displays a table that shows Earth pounds and their equivalent moon weight. Have the table run from 1 to 100 pounds. Output a newline every 25 pounds.
I think I'm close , here's what I have so far.
// This project the For Loop, the If statement, and code blocks
//to display a program that converts Metrics into Feet
#include <iostream>
using namespace std;
int main()
{
int temp;
double e; // holds the wieght on earth
double m; // holds the conversion to moon wieght
int counter;
int d;
counter = 0; // counter is initially set at 0
for(d= 1.0; e <= 100; e++) {
m = e / 17.; // convert to meters
cout << e << "earth is" << m << " moon.\n";
cin >> temp;
counter++; //encrement the counter with each loop iteration
// every tenth line, print a blank line
if ( counter == 100 ) {
cout << " \n "; // output a blank line
counter = 0; // reset the counter
}
}
cin >> temp;
return 0;
}

Probably this should be
for(e= 1.0; e <= 100; e++)
painterdave wrote: // every tenth line, print a blank line
if ( counter == 100 ) {
cout << " \n "; // output a blank line
}
Shouldn't that be:
if (counter==25)
{
cout << endl;
counter=0;
}
else
{
counter++
}

I am just starting on this journey, so
any help is apreciated, it's always good to get another point of view.
What makes it even more difficult is when the text that you are using , is a little bit off, or out of date or somehtings missing. I mean when you do it the way they tell you to do it , and it doesn't work ?, I thought it was me , but a friend of mine who is a programmer, had to give it a couple of fixes.

Well, I can feel your pain. Anyway, don't worry, sooner you will laugh at your starting difficulty.

I would always use integral values for loop counters thus:
for (counter = 1; counter <= 100; ++counter)
{
d = (double)counter;
m = d * 0.17;
cout << e << "earth is" << m << " moon.\n";
if (0 == counter % 25)
cout << endl;
}

e is never initialized. You should also consider making it an int. I would not worry about anything else until you have a loop that can count from 1 to 100.

Might help if you understood what percent means. Also, what does meters have to do with the problem what dealing in weight?

This class is used to save the pix paths in the ListBox into a file. CListItemData is a class that stores
additional info for every item in ListBox. This class operates correctly.
void CCfgFile::Serialize( const CListItemData& lid, const CListBox& lst )
{
loadConfigFile();
fPic.Seek( sizeof( CONFIGFILE_HEADER ), CFile::begin );
CString str;
int i = 0;
while( i < lst.GetCount() )
{
lst.GetText( i, str );
str = lid.GetDir(i) + _T("\\") + str + _T(".") + lid.GetType(i);
memset( rcd.strPath, 0, sizeof( rcd.strPath ) );
memset( rcd.nStyle, 0, sizeof( rcd.nStyle ) );
strcpy( rcd.strPath, str );
itoa( lid.GetStyle(i), rcd.nStyle, 10 );
rcd.nStyle[1] = '\0';
fPic.Write( &rcd, sizeof( CONFIGFILE_RECORD ) );
i++;
}
fPic.Close();
}
The prob occurs. Sometimes the file buffer is updated and the ListBox can show the updated data. But after I exit the proram, the disk file is not updated. This really confuses me. Even if I use CFile::Flush(), it's the same. Anyone could help me out? Really thanx.

I think there is not enough information about your problem in your post, so can you just provide some more information? Like definition of the struct type of "rcd"?
Besides, maybe you can try to debug the application to find the reason of your problem
|

What is fPic? That's a pretty crucial bit of missing data...
How is the file opened?
Could it be failing on the opening (ie, already open elsewhere) and you're not handling the errors from a failed opening?

You're first writing a CONFIGFILE_HEADER record to the file, rewinding it, and then writing one or more CONFIGFILE_RECORD records to it.  Is that the intent?

This will not always result in the same path.

Your ret is set to false and the return value from the file open is returned but never used in your main function.

Thank y'all! I've got it solved with the help of DavidCrow. Actually, ::GetCurrentDirectory() may return inconsistent paths.

I am making a desktop development.But there is a problem that I can't solve till now.In the development I have to add some command buttons to the listbox.And the first item is different from others.It is like a header with text.So how can I do it.Thanks.

Just try with the subclassing, You have subclass a control to get the rid, try this example Control Subclassing[^]

Hi all--
I've got a program where you click and add points to make a polygon using a linked list, and now I want it where by pressing a button it will take the points on the polygon and make it a cubic b spline curve. However I have no experience with the b spline curves and am having trouble with were to start. So I was wondering if you would be able to help me with the pseudo code for this, using C so that I can better understand what I'm trying to do. Here is what I have come up with so far (which isn't much unfortunately):
Create a drawCurve function that traverses the linked list in order.
Take the first four points to draw the spline curve, then the next one over each time.
[insert how to do the math here (of which I am confused about)]
Use a state machine to implement. So pressing a button of my choice will change between the drawing polygon state and the draw curve state.
Thank you very much for your help.
