Yes, I have the hwnd. But as I mentioned, unless there's a way to get the process id or handle from a hwnd, I need to enumerate all processes and enumerate all their windows and compare those handles to the handle for the window I want to find, thus finding the owning process.
Get me?

Is there a way to convert a unicode string as the user would type it into an array of unicode characters as they would be displayed?
For example, typing unicode character 0x0628 followed by 0x0627 will actually display as unicode character 0xfe91 followed by 0xfe8e.
Thanks
...Matt

The simple answer is yes. Have I done it? No! If you want to translate a series of values (combined values – in Unicode) to a character with a specific value (which Unicode usually supplies), then you are dealing with a display representation of the character and it is up to the designer of the font display code to decide how to do it. Unfortunately most programmers who are privy to that information are under contract not to tell.
If you need to just do a translation from combined values to a different Unicode value, then you are probably on you own; although I have the impression that they do what you are trying to do. It should not be too difficult, the character listings are online and the official information is available for purchase.
Good Luck!

I am curious, what development environment are you using? That is basic information that was available to programmers before the advent of Windows (or other modern OSs).

I need to pass a variable (via CWnd parameter) to CDialog from CWnd derived class.
I did this
CCC_Dialog_EditFile *pDlg = new CCC_Dialog_EditFile(this );
pDlg->DoModal();
In CDialog I now have CWnd pointer *pParent.
Obviously this pointer is to the base class, is it?
Silly - but I cannot figure out how to get to my calling class variables and process them in the dialog. (I tried handle etc without success.)
This is pretty basic but I am lost.
I am after displaying text data in rich text control.
I can do this in modeless dialog just fine, but I need modal dialog.
I even tried to build another constructor but the compiler did not like it.
Neither do I because the dialog would work only for specific class anyway.
CCC_Dialog_EditFile((CCC_Form_Edit*) pParent = NULL);
Just FYI here is the VC 6.0 error
error C2629: unexpected 'class CCC_Dialog_EditFile ('
error C2238: unexpected token(s) preceding ';'
Any help would be greatly appreciated.
Thanks
Vaclav

try:
CCC_Dialog_EditFile(CCC_Form_Edit* pParent = NULL);
|
|
|
|

That is the format the compiler complains about.
|
|
|
|
|
but it's not the format you posted in your original comment.

Sorry I missed some details here.
I tried both casts - with and without parenthesis - makes no difference
.
Get same errors.

I tried to build a different constructor then I get this error.
class CCC_Dialog_EditFile : public CDialog
{
// Construction
public:
CCC_Dialog_EditFile(CCC_Form_Edit* pParent = NULL);
CCC_Dialog_EditFile(CWnd* pParent = NULL); // standard constructor
Anyway,
I think I found the solution. I "pull" the calling class window from the pParent handle like this
CCC_Form_Edit * pWnd = (CCC_Form_Edit*)FromHandle(pParent->m_hWnd);
Does it makes sense? It still ties the dialog to one class but it will work for now.
I am still interested in proper solution, this is a hack!
Thanks for all your input.
Cheers
Vaclav

How's the compiler going to differentiate between the two?

No, I'm still unclear as to what you are doing?

No. The 'this' pointer is to the parent window.
If you're wanting to have the dialog manipulate values in the parent, there are a couple of ways to do that. You can either pass pointers to the variables in the dialog's constructor, or you can pass the variable values in, and then have a way of retrieving them. I prefer the second method, since it's easier to handle the case where the use clicks the Cancel button to close the dialog.
The dialog class looks like this:
class CMyDialog : public CDialog {
public:
CMyDialog(Type1 initial_value_1,
Type2 initial_value_2,
CWnd *pParent = NULL);
void GetValues(Type1 *value_1,
Type2 *value_2,
};
CMyDialog::CMyDialog(Type1 initial_value_1,
Type2 initial_value_2,
CWnd *pParent)
: CDialog(pParent),
Value1(initial_value_1),
Value2(initial_value_2),
{
}
void CMyDialog::GetValues(Type1 *value_1,
Type2 *value_2,
{
*value_1 = Value1;
*value_2 = Value2;
}and you use it like this:
Type1 my_value_1;
Type2 my_value_2;
CMyDialog my_dialog(my_value_1,
my_value_2,
this);
if (my_dialog.DoModal() == IDOK) {
my_dialog.GetValues(&my_value_1,
&my_value_2,
);
}

Thanks Gary,
it looks like I am getting closer to what I want to accomplish.
I cobbled this "solution"
The parrent calls the dialog with (this) pointer.
The dialog retrieves handle from passed pointer and than I build another
CWnd to get to the caller variables. ( Can't show you now because my mashine is overloaded with restoring the RAID arrays and I don't want to get any " cannnot access because it is in use ").
I have not gotten to actual work on the variables - still working on the dialog "results" actions.
I like your approch and will try it.
But...I am still curious why the "standard" constructor get the CWnd pParent and how to use this pParent pointer "properly".
Cheers
Vaclav

Passing the parent window to the dialog constructor lets the dialog disable the parent window if the dialog is used modally. You've seen examples of this before. For example, when you run Notepad and select File, Print, the Print dialog is modal and you're not allowed to interact with the Notepad window again until you dismiss the Print dialog.
Most of the time, passing this parent window pointer to the standard constructor is sufficient. If you need the parent window later on in the dialog for some reason, it's better to call the GetParent() function rather than use a saved copy of the parent window pointer.

J want to add an icon i one of the column i my CGridCtrl.
Firts i add a class:
class MGrid : public CGridCtrl
{
...
public:
CImageList m_ImageList;
}
In my function Init_grid:
m_ImageList.Create(MAKEINTRESOURCE(IDB_IMAGES), 16, 1, RGB(255,255,255));
SetImageList(&m_ImageList);
(IDB_IMAGES is a smallicon.bmp file)
Now I want to add an icon in 2 column of my grid:
void MGrid::Draw_icon(int ARow)
{
int ACol = 0;
int ilosc_col = GetColumnCount();
CString str = "";
GV_ITEM Item;
for(ACol = 1; ACol <= ilosc_col; ACol++)
{
Item.row = ARow;
Item.col = ACol;
if(ACol == 2)
{
Item.mask = GVIF_TEXT;
str.Format(_T("Column %d"), ACol);
Item.strText = str;
Item.iImage = 1;
Item.mask |= (GVIF_IMAGE);
SetItem(&Item);
}
}
What I see is a string "Column 1" (..n) but there is no image in the column.
Can you help me?
Regards
