I'm not sure what a "function for editbox" is.

I indicated here that you should use a CEdit object instead.

Hi david ...
Iam following ur suggestions truely...thanku so much for ur patience...
Asserion faliure is showing in AFXWIN2.lnl line 881....
Dont know how to solve that...
OnInitDialog is not allowing to keep CEdit m_edit1;
m_edit1.SetLimitText (1000); in it....
What i meant by function is if we click on EN_CHANGE it will ask for add function OnChangeEdit1()..
Presently iam stuck with CEdit SetlimitText,SetWindowText and GetWindowText.. 
plz bear with me

You should start by looking at line #881 of afxwin2.inl. It is asserting that a valid window handle exists, which obviously does not.

Are you declaring this variable in OnInitDialog()?

By using SetWindowText() and GetWindowText().

I have written Installation using Visual Studio 2008 Setup project. I have created a GUI for installing specific product (using check box dialog). but I need the same gui for uninstallation also.
Means if unchecked that product should be uninstalled. all other products should remain same. any suggestion how to do it in Visual Studio 2008 setup project.I used only C++ base installation. No .net dependencies.

Hi,
I have been using DDX_CONTROL to Attach My Cricheditctrl to my resource multiline edit control
For some reason this stops the CRichedit.Streamin from working
With ::Create no problem
Was wondering if anybody had any insights
As I always like to know the reason why things work or Don't
thankx...

Please explain what you mean by "stops from working". Does it crash, does it stop on an assert, does it simply not load the content? How and where did you try to use it?

The content doesn't load
Maybe the FrameWork expects me to use DDX
to read and write data after connecting the
resource item to the CRichEditctrl object don't
know
but If I do CRichedictrlptr *CRicheditrl =
CDialog.GetDlgItem(IDC_RICHEDIT)
I able to populate the Richedit using the
Streamin method

I highly doubt that.
Could it be that maybe you are trying to load that content before DoDataExchange runned?

I have a call to the Default
CDialog::DoDataexchange
In my overridable version
Not sure what that does I'll comment that out
and See what happens
Thankx

I believe you misunderstod something.

The streamin method should work after DDX_CONTROL
I have to have a closer look at my Code
at this point I am thinking that I dont have to Call UpdateData as that is
Done automatically by the default CDialog::Oninitdialog
Which I have in my OnInitdialog
I'll take a closer look
thankx

I need to get OS info,
1. name: i.e. Windows XP, WinNT 4 etc.
2. edition: i.e. Server, professional, standard etc.
The info should start from Win98 (or Win2K) and up to latest one.
- is the latest one Windows 7 now?
I have C code to show up to XP, do you have code for new OS?
|

|

Use the GetVersionEx[^] API to get the version of the running OS.
Look into the remarks section of the documentation for OSVERSIONINFOEX[^] for the list of OS codes.

Hi all,
I have a problem in implementing tree traversal using c++, i want to display the output of tree traversal: inorder, preorder, postorder in tree form, this means i should include some graphic codes so as to display the tree format on the screen. I don't have idea how to use graphics to display the output on the screen.
Please help me

See here.
I've also seen implementations where the tree was laying on its side. It's a recursive approach.

First you need to learn how to draw lines on the screen. If you're using MFC, look at OnDraw and the CDC class. Then you can look at writing text if you need to do that.
For arranging the binary tree on the screen, a good approach is to space the leaf nodes out evenly horizontally. Then each parent node goes halfway between its sons, on the row above.

Hi guys ,
I've problem with C in Linux, and just i need to pass args to execvp(args[0],args) to the main function and after creating child process and the code is :
#include <stdio.h>
#include <string.h>
#include <signal.h>
#include <stdlib.h>
#include <sys/wait.h>
#include <sys/types.h>
#include <unistd.h>
#define MAX_LINE 80
void setup(char inputBuffer[],char *args[],int *background)
{
int i;
int cmd=0;
int l;
scanf("%s",inputBuffer);
if("%d",strlen(inputBuffer)>80)
{
printf("error the maximum size is 80\n");
exit(-1);
}
else
{
args = &inputBuffer;
}
}
int main(void)
{
char inputBuffer[MAX_LINE];
int background =0;
char *args[MAX_LINE/2+1];
char *command;
while(1)
{
background=0;
printf("Command ->");
setup(inputBuffer,args,&background);
pid_t pChild;
pChild = fork();
if(pChild <0){
printf("Error\n");
exit(-1);
}
if(pChild==0)
{
execvp(args[0],args);
}
else {
if(background=1);
wait(NULL);
printf("Child process completed\n");
}
exit(0);
}
}

So what's the problem?

What's this?

Your compiler should at least be warning you about this, if not outright complaining.

Im trying to update the args to pass into main function to (execvp) and run the command for example
ls - 1
or sh> cat pro.c
just i need to pass args to the main function to execute the command

Then you're gonna need to change its signature to:
main( int argc, char *argv[] )

ok! i changed the signature but the output only "Child process completed")
