Hi I want to change WIDTH of my rich edit control as user types text in it, so that it displays the entire text instead of scrolling text horizontally. My rich edit is a multiline control

I have used EN_REQUESTRESIZE notification msg but this works only for adjusting height of control and EN_REQUESTRESIZE is working perfectly in case of height, i.e I use to change the control height when i get this msg to show all lines of text.

kindly help!!!! its urgent

If your problem is the scroll-bars that unexpectedly appear even after you resized the rich edit control during ENM_REQUESTRESIZE, then please note that the new control size probably should include the width of the control’s borders. Try to specify a little bigger size.

Otherwise, what exactly occurs when you type a long line of text?

Thanks Viorel,
No the problem is not with scroll-bars the problem is that when user types some text in the control and the text reaches right border of control than how much should i increase width of my edit control (based on current font size, face name etc..) so that the next character typed, is visible and no scroll bar or word-wrapping should occur.

And when the control's width reaches right border of dialog than word wrapping should occur.

thanks

Hi

If you want somthing more serious then volume serial number (GetVolumeInformation) which you can change, try to use http://www.codeproject.com/csharp/hard_disk_serialNo.asp. Additionally here is [^] whole another project. In my case it doesn't work properly with all drives but you can try.

Man, your post is missing a lot of informations for us to help you. You even didn't described the problem. What does "It can't work" means ?
Anyway, I have THE ultimate solution that can help you in every situation like that: use your debugger. It will provide you with all the information you need to track the problem.

IMO, it seems as if there is a total lack of knowledge about debugging for certain posters.
Personally, I single-step all vital code before turning it over to the users. It has saved me heaps of work, during the years.

Hello li zhiyuan,
the warning is due to the fact that your are assigning a double value to a variable of type long. i.e.

double d = 3.5f;<br />
long l = d;

and the warning says that you will loose your data and l will caontain only 3 instad of 3.5.

if this is ok for you than you can suppress this warning by typecasting.
i.e.

double d = 3.5f;<br />
long l = (long)d;

hope this answers your quetion.

Also have you added message handler for the new menues that you are creating?? Confused | :confused:

Hi I added a class in my MFC dialog based project. Now i want to declare a pointer object of my dialog class in .cpp file of newly added class to access members of dialog class in that cpp file. I declared that pointer like this

CFileSenderDlg *fsD = new CFileSenderDlg;

But program crashes at the point where i use this pointer to access a member function of dialog class. What it the mistake i am doing? Can anyone please help me in this regard?
Thank you.

The code seems very clean.
1. Check whether the pointer get allocated properly or not (NULL or Junk value).
2. Check for the missing resources, which hadn' is not removed on deleting the control.
3. Check the message handlers

Sorry i was wrong. In fact error occures when i try to declare the pointer.
When i tried to debug it, It took me to afxwin1.inl and current pointer was on following lines. Can you please tell me what is the problem?

_AFXWIN_INLINE HINSTANCE AFXAPI AfxGetResourceHandle()<br />
	{ ASSERT(afxCurrentResourceHandle != NULL);

After this, you should create the dialog box also like:
fsD->Create(IDD_WHATEVER,Parent);

Also check that the actual dialog resource is really present by looking at the resource view, and then checking the ID for the dialog.

this is this.

User defined buttons on the MessageBoxes

Hi

Right now I am working with MessageBoxes.Is there a way to define my own Buttons for the MessageBox with a caption of my wish and handle the ButtonClicked event?

Thanks in advance

I don't think that is easily possible with the default messagebox. However, you can create a custom message box by defining your own dialog box resource, and returning the proper values from it (EndDialog (VALUE_HERE) ) under different buttons, with everything under your control (caption, focus, text size etc), and using it with its DoModal() function.

this is this.

Even if there are some methods for affecting the standard system’s message box (see, for instance, http://www.codeproject.com/cpp/dMsgBox.asp[^]), I think you should consider creating of your own dialog, with buttons you need.

Hi friends
I want to ask if i declare a function like

friend ostream& operator<<(ostream& , date&); in a class declaration. Does it become friend function of that class. Can it access private members of class? If yes how i should define it in .cpp file of that class?

Thank you

yes, that's why the friend keyword is made for.

~~no. friend functions/classes access at most protected members (and of course public ones), but not private.~~
yes...

Aqueel wrote:

you declare it in the class which it is a friend of :

class CMyClass {
    //....
 
  public:
    friend ostream& operator << (ostream&, date&);
};

and then, define it in a .cpp (generally, in the .cpp which defines your class' members) :

ostream& CMyClass::operator << (ostream& os, date& d) {
    //...
    return os;
}
