What about overriding CDialogImpl::DialogProc()?

i override that function but did not worked either.
here was code i was using

static virtual LRESULT CALLBACK DialogProc(HWND hWnd,UINT uMsg,WPARAM wParam,LPARAM lParam);<br />
LRESULT CMiniBubbleDialog::DialogProc(HWND hWnd,UINT uMsg,WPARAM wParam,LPARAM lParam)<br />
 {<br />
 		WriteEventLog1("Proc called");<br />
 		switch(uMsg)<br />
 		{<br />
 		case WM_MOVE:<br />
 			 WriteEventLog1("Mouse is moved");<br />
 			 break;<br />
 		case WM_LBUTTONDOWN:<br />
 			 WriteEventLog1("Lbutton Down");<br />
 		}<br />
 		return 0;<br />
 }<br />

but did not worked.

Regards.

Maybe override CDialogImpl::GetDialogProc() and return a pointer to your dialog proc.

You can Override OnCancel();
Like this!.

void YourClassName::OnCancel()
{
// TODO: Add your specialized code here and/or call the base class

CDialog::OnCancel();
}

Thanks and Regards.

as suggested by santosh, you can override it or comment the following code
//CDialog::OnCancel();

radio button

Hi, is there any simple way how to change radio-button,check box and group box TEXT COLOR?
OnCtlColor evidently doesn't work Frown | :-(

Or some class to do it for me?
Thanx

Try playing around with this...

    ON_MESSAGE(WM_CTLCOLORSTATIC, OnCtlColorStatic)

...

// Just an example - there's stuff in this method you don't need
//   and/or that isn't used

LRESULT CMyDlg::OnCtlColorStatic( WPARAM wParam, LPARAM lParam)
{
    LRESULT lRet = Default();

    HDC hDC = (HDC)wParam;
    HWND hWnd = (HWND)lParam;

    ::SetTextColor(hDC, RGB(0x00,0xFF,0xFF));
    //::SetBkColor(hDC, RGB(0xFF,0x00,0x00));
    ::SetBkMode(hDC, TRANSPARENT);

    //return lRet;
    return (LRESULT)::GetStockObject(NULL_BRUSH);
}

Don't ask me why WM_CTLCOLORSTATIC is used for radio buttons,
check boxes, and group boxes Smile | :)

Maybe because their text is static!

thank you,
it pushed me closer. I tried your code - and modified it and try it again:
- it works to set backgroung color of all controls like radio, check and so on
but only Text controls change text color. Radio-Button control, Check-box control even Group-box controls have still default color.

I am getting this messages for them but SetTextColor function seems to have no effect called from there ??

It works for me on XP SP2 without the common controls 6.0.0.0 manifest entry (no themes).

With the themes, radio buttons work, check boxes and group boxes do not.

There's no guarantee any of this will work, especially with buttons.
You have to experiment, and then hope it doesn't change in the future.

Owner drawn or custom controls are the only guarantee...

Good luck Smile | :)

clear now,
i try to take manifest entry away and everything works fine.
Now I wonder if is possible to skip manifest just for some part
of program - i dont want to lose messageboxes and this better looking Win XP advantages stuff.
Thank you for help and advices

I have multiple levels of functions that I would like to have pointing to the same data. I have things set up like so. I have an issue that when I get into func2.. str1[0].myStr does not have data; I'm screwing this up somewhere.

<br />
struct myStruct{<br />
    int myInt;<br />
    CString myStr;<br />
};<br />
<br />
void main()<br />
{<br />
    myStruct *st1 = new myStruct[10];<br />
    st1[0].myStr = "test1";  <br />
    Class1 *cls1 = new Class1(st1[0]);<br />
}<br />
<br />
///////  CLASS 1<br />
class Class1<br />
{<br />
    myStruct *m_pSt1;<br />
}<br />
<br />
void Class1:Class1(myStruct &st2)<br />
{<br />
    m_pSt1 = &st2;<br />
    Class2 *cls2 = new Class2(m_pSt1->myStr);<br />
}<br />
<br />
void Class1::OnFileSave()<br />
{<br />
    //get value of str<br />
    MessageBox(m_pSt1->myStr);   //this has no data!! but is fine if Class2::OnEventFunc2() gets processed or is omitted<br />
}<br />
<br />
<br />
<br />
///////  CLASS 2<br />
class Class2<br />
{<br />
    CString *pMyStr;<br />
};<br />
<br />
void Class2::Class2(CString &myStr2)<br />
{<br />
   m_pMyStr = &myStr2<br />
}<br />
<br />
void Class2::OnEventFunc2()<br />
{<br />
    *m_pMyStr = "test3";  //when this is omitted everything works ok<br />
    //if it is there, str1[0].myStr does not have data, even if this<br />
    //function is never called.<br />
}<br />

Thanks in advance for any help on this Smile | :)

I have an issue

what knid of issue ? compilation ? linkage ? execution ?
what's the error message ?

BTW, if you use pMyStr inside func2() without declaring it previously, how can you think it can work ?

ps: please use <pre></pre> tags when posting code samples...

srry.. had to edit the code a little bit. I can't post the entire code so i'm trying to break it down.
the pointers in the functions are actually member pointers so the entire class has scope of the pointer. By the time Class to is created myst1[0].str no longer has data. I will edit the code one more time to be more specific.

i have a question. do you really want the member pMyStr to be a CString pointer ??

anyway, what does this line produce if you replace the line within func2() :

*pMyStr = CString("test3");

the point is, The pointer in Class2 shows that it is pointing to the write place, because when I set it in Class 2 it works. And In Class1, setting the value by pointer works also, so I know that one is pointing to the right place to. It is the value that is set in the main function that is somehow getting overwritten or NULL'ed, and i can't understand why.

just a guess, try to use your debugger with some breakpoints to figure out where the data is NULL'ed.

also, if you can use references instead of pointers, i advise you to ; using pointers and allocating memory on the heap is driving you into trouble if you don't handle them perfectly...

ok.. but how do I get the reference into the scope of the intire class. I was using member pointers to do it. is their another way?

class Class1
{
int *m_ptr;
}
Class1::Class1(int& num)
{
m_ptr = #
}
Class1::func1()
{
//I have access to the reference
m_ptr = 5;
}
