Hello
I have been working on a program and been getting some good help from everyone thank you
well i am back again with another question like i have said before i am still new to this.
i am trying to add a dialog to my program so that when i click on a button it will bring up a new dialog box with buttons and stuff on it. i have been searching tutorials but i might have over looked it
so if anyone knows of tutorials that would be great
thank you for you time

Hi
OK bring up your project and click on the resource view tab.
Expand the resources +
right click on the dialog folder
select insert dialog
right click on the dialog and select properties
Name the dialog something like IDD_MYDIALOG
right click on the dialog and select class wizard
Add a class dlg appears
select create a new class
call the new class something like CMyDialog
Alway start your classes with the capital C (it does not have to be this way but it will help later)
Select the base class as CDialog
select OK
If your project is a sdi or mdi select mainframe or view class
If you project is a dialog select the maindlg class
Select the cpp of the main class and at the top among the other #include statements insert the following
#include "MyDialog.h"
Note with left the C off the include statement.
Now put a button on your main dialog and right click and change the properties to IDC_MYBUTTON
double click on the button and add a handler
it will look like this
void MyMainClass::OnMybutton()
{
// TODO: Add your control notification handler code here
}
now add the follow code to the OnMyButton handler
CMyDialog dlg;
if(dlg.DoModal() == IDOK){
AfxMessageBox("We are back in the main class and you selected OK in the child dialog MyDialog");
}
So the button handler should look like this
void MyMainClass::OnMybutton()
{
CMyDialog dlg;
if(dlg.DoModal() == IDOK){
AfxMessageBox("We are back in the main class and you selected OK in the child dialog MyDialog");
}
}
compile and run
So what you have done is:
1. insert a new resource MyDialog
2. created a new class based on CDialog
3. Added a include statement to the class you wish to call the dialog from
4. added a button
5. created a handler for the button
6. added the code to call the button
7. returned to the calling class.
good luck and keep up the good work!

Are you using MFC or the Win32 API?

is there any way to pass a variable argument list on to another function (I'm trying to make a wrapper for sprintf). for example:
void myfunc(char* format, .../*args*/)
{
//some code...
//how do i pass the argument list to sprintf???
sprintf(acharbuffer, format, ?HOW_DO_I_PASS_THE_ARGS?);
}
-thanks

BOOL MyAppDlg::SamplePassArgs(CString *pstr, int dVar, UINT uVar, CString strvar)
Now you may also overload the function
BOOL MyAppDlg::SamplePassArgs(int dvar)
or
BOOL MyAppDlg::SamplePassArgs(CString strvaar)
or
BOOL MyAppDlg::SamplePassArgs()

Hi BaldwinMartin,
I'm sorry, I don't understand your reply at all. I'm not using MFC, and I think my function definition was ok, I just didn't know how to call sprintf inside myfunc with the argument list that was passed into myfunc. For example, I want to call myfunc like
myfunc("2 ints: %i, %i\n", 100, 200);
and then inside myfunc call sprintf with the var list. Sorry if I'm not explaining it right...
Thanks for your reply though!

You need to use va_*() functions.
e.g. :
Format( const char *F, ... )
{
if( !F ) return;
char buff[1024] = '\0';
va_list l;
va_start(l, F);
_vsnprintf(buff, 1020, F, l);
va_end(l);
}
... or you could use the other va_*() functions to walk the argument list and do your own parsing.

Hello all! I'm trying to make a instant messaging app for my home network, and I am using RTF controls for text input and conversation display. I am currently having a problem, though, appending (for testing and later implementation) the string I enter in the text input RTF control to the conversation RTF control preserving all the RTF formatting information. Any ideas on how I would go about doing this?

What derived view are you using?
CBL

Actually, I'm not using a view. The conversation dialog has two CRichEditCtrl controls (I've extended the class for easier RTF information extraction to CString using a function called "CString GetText(bool bGetRTF)" (the bool parameter tells me to get plaintext or RTF formatted info)). So basically, I used Visual C++'s dialog editor and added two Rich Edit controls to the dialog. That's basically my setup. Thanx!

If i want to hook a rich text box on a window, what msg's should i be looking for.
I.E. when a rich text box gets data set to it, what kind of WM_ msgs (or EM_) are processed by the system? what should my hook look for?

Anyone knows how to?
Thanks

Are you looking for the function atoi? this is an old but much maligned function. If it is you you only have to say "Thanks masked man - you have saved my life"
go cobol young man - go cobol

cobol just told you, how to convert from str to int so you have that right?
int x = atoi("123456");
now to change that back to an int?
ok right out of MSDN
char *string, *stopstring;
double x;
long l; // or int
int base;
unsigned long ul;
string = "3.1415926This stopped it";
x = strtod( string, &stopstring );
printf( "string = %s\n", string );
printf(" strtod = %f\n", x );
printf(" Stopped scan at: %s\n\n", stopstring );
string = "-10110134932This stopped it";
l = strtol( string, &stopstring, 10 );
printf( "string = %s", string );
printf(" strtol = %ld", l );
printf(" Stopped scan at: %s", stopstring );
string = "10110134932";

You can use the atoi() function if it a CString.
If it is LPTSTR or some other string stuff I prefer writing them on an invisible static text box and retrieving them as an interger.
I hope this helps!
Well... I am a beginner ...

Yuck! (the static text box thing) But forgivable for a beginner (just  )
I think it's time you were introduced to the boost library, and in particular the lexical_cast<> template.
Also note that an LPTSTR (long pointer to a TCHAR string) can be one of two things - a pointer to a char array (char *), or a pointer to a wide-char string (wchar_t *, which is a full type in VC.NET, and a typedef for short in VC6)
The T bit is the TCHAR thing mentioned earlier - TCHAR means char or wchar_t, depending on if you are building an ANSI/ASCII version of your code, or a UNICODE one.
I would suggest that you look up the relevant functions for conversions, which can handle unicode or ansi strings as necessary (eg, _tcstoul for converting a LPTSTR to an unsigned long).
