CProgressCtrl *Progress = new CProgressCtrl;
Progress->Create(WS_CHILD | WS_VISIBLE, CRect(10, 10, 288, 35), this,0x16);
Progress->SetRange(0, 100);

I suspect you need to run your main code in a seperate thread so that your progress bar is responsive.

Please, reply here, I don't respond to emails b/c I don't give out my address.
I'm sorry, but you'll need to read up on multithreading, if you don't understand what I meant. Yes, you can put it in your status bar, I'm sure there are articles on how to do that.

Hi,
Why you put the code inside the custom draw function (OnNMCustomdrawProgress1) of the progress bar itself. This function is called only if the Progreesbar is having OWner draw style.Whether you want to show another progress control when the custom draw function of the progress1 is called???.
thanks,
Nitheesh

Hi,
Place your ProgressBar Creation code in OnInitDialog (override it) and make control hidden. Then in your button click event handler make it visible and set its bar position's.
Or
you can place a progress control bar and make it visible false. then do in button click event handler as said above.
And increment the bar position in the list fill function.
thanks

So which is it, empty or invisible?
Did you mean to create the control at run time rather than at dsign time?

I'm using Visual C++ 6.0 - I'm new to windows programming.
I have a pop-up window where users enter data. It is setup as dialog using Visual C++. Sometimes I would like to display a note in this window that says "inches" and other times I would like this note to say "millimeters". I learned how to put up static messages, but I don't understand how to change them based on a variable in my C++ code. What is the simplest approach? Thanks ahead of time.

Are you using MFC? If so, you can add a CStatic control variable
to the window class, and use the CStatic::SetWindowText() method to
change the control's text.
You should be able to add the control object from the dialog editor...
right click the text control and chose "Add variable..." (I can't remember
exactly in VC6).
*edit* Actually, adding a string variable for the static control and using <br />
DDX is another possibly simpler MFC solution. I seem to have neglected that<br />
previously 
If you use straight Win32, you can use the SetWindowText() API directly
on the control, something like:
HWND hwndControl = ::GetDlgItem(hwndDialog, IDC_MYSTATICCONTROL);
::SetWindowText(hwndControl, _T("New Text!"));

Thanks for the reply. Your answer changes the title of the window, but it led me to find the function:
void SetDlgItemText( int nID, LPCTSTR lpszString );
which seems to work okay for what I want.

For SetWindowText you need to a handle to controls but with SetDlgItemText you can use of control id.

Not if the right HWNDs are used. For a static text/edit control HWNDs, the text
of the control should be set.
SetDlgItemText is great - it combines GetDlgItem() with SetWindowText() into one call

you have to change name of IDC_STATIC to some else,to make editor aware that you want to add variable to that static control!

You can use of Get/SetwindowText or WM_GETTEXT/WM_SETTEXT for get or set text toa control.

How can I free memory before returning the value in my function?. Here's the code, thank you very much.
int FindString(char*s, char* what, int len, int len2)
{
char * x = s;
for (int i = 0;i<len;i++,*x++)
{
if(memicmp(x,what,len2) == 0)
{
cout <<; "I found it @ " << i << endl;
return i;
}
}
return -1;
}
char *rr(char*s)
{
char cc[4] = {0x00,0x00,0x00,0x00};
int i =FindString(s,cc,512,4);
if( i > 0)
{
char * New = new char[i];
memcpy(New,s,i);
// How can I use 'delete' here before returning New???
return New;
}
return NULL;
}

Why do you want to delete the array before returning the pointer
to the caller? What are you trying to achieve?

You don't delete it before returning the Pointer. The function that called FindString receives this pointer. This calling function can do it's thing with the pointer, and, if needed return it again. When you're done with the value of the pointer you must call delete, otherwise you leak the memory. As soon as you call delete, the value of the pointer points no longer to valid memory, and may not be used again. Using it's value again is an error, and will lead sooner or later to unpredictible behaviour or even crashes.

Thanks for your answer. I was wondering if I had to return that pointer how to remove it if it was my desired return value. Thanks for your answer, Bram van Kampen. This way i'd be doing it fine??
<code>
int FindString(char*s, char* what, int len, int len2)
{
char * x = s;
for (int i = 0;i<len;i++,*x++)
{
if(memicmp(x,what,len2) == 0)
{
cout << "I found it @ " << i << endl;
return i;
}
}
return -1;
}
char *rr(char*s)
{
char cc[4] = {0x00,0x00,0x00,0x00};
char ReturnArray[1024] = {0};
int i =FindString(s,cc,512,4);
if( i > 0)
{
char * New = new char[i];
memcpy(New,s,i);
memcpy(ReturnArray,s,i);
delete[] New;
return ReturnArray;
}
return NULL;
} </code>

Hi,
U declared ReturnArray as a local buffer. ie it's scope is only within the function rr. So after the execution of rr ,ReturnArray will be destroyed. i think u r going to get a "memory cannot be read error" . am i right?.
thanks
