I'm not exactly sure what you're asking. Are you saying that when the context menu is dismissed it takes your application a long time to redraw the area that was obscured by the menu?

win32 app window not tabbing to WS_TABSTOP style edit controls

Hi all,

I'm currently working on a program in C for a Win32 App where my parent window and its children have been created programmatically using CreateWindowEx(). I've set the extended style for the parent window to WS_EX_CONTROLPARENT and its children (edit controls) style to WS_CHILD | WS_TABSTOP, but no matter what I do, when I click inside the first edit control, type in the value, and then press TAB, the focus does not shift to the next window with WS_TABSTOP. Am I missing something here? The way I understood it, these two styles were all I would need, yet I am still unable to shift the focus from one edit control to the next.

All help is welcome. Thanks in advance.

Is the IsDialogMessage[^] function in your message pump? If not it will not work as you expect as it's the function which contains all the dialog box navigation magic.

So you're saying I just need to add IsDialogMessage() to my GetMessage() loop? Would I switch the message on the spot, or would I switch it in the WindowProc?

Thank you so far for you help.

The message pump would have to look something like this:

MSG m;
while (GetMessage(&m, NULL, 0, 0))
{
    if (!IsDialogMessage(hDialog, &m))
    {
        TranslateMessage(&m);
        DispatchMessage(&m);
    }
}

Note that things just work for modal dialogs as they implement their own message pumps which do the right thing. For modeless dialog and other windows you have to do it yourself.

You said you wanted to communicate over the Internet with sockets (and previously worked with MFC and Win32).
Do you have a specific question or are you looking for tutorials?

matrix x vector -> vector

In a template project I am working on I have basic matrix product fine.

so given I have that working, I was looking at how to deal with matrix and vector product correctly as my books lack the algorithm I need.

vector operator*(const matrix that) {
vector result;
for (int i = 0; i < that.data.size{}; i++)
for (int j = 0; j < that.data[].size(); j++)
....
return vector;
}

I am not sure how this loop needs to work

I want to disable some shortcuts in CRichEdit control. Using PreTranslateMsg it is done but how to block some shortcut events ??
For example Left align , right align.
Thanks in advance.

Operator Or

Hi,

I'd like write a function doing sth like that.

if(a == 5) 
val = val | 1000

if( b == 20)
val= val | 100

in the end if i have the both condictions corrects i'd like to have 1100 as result on val. but i always do 1000.

which operator should i use to have the 1100 as resut.

why are you using bitwise OR, if what you really want is addition ?

Being slightly cynical addition sounds like the operator you neeed... With your statements val is going to end up containing 1004 as there's a large overlap in the bits set between the bit pattern for 1000 (1111101000b) and the bit pattern for 100 (1100100b).

If you're trying to fiddle individual bits (i.e. turn bits with OR 1, turn them off with AND 0) then perhaps encode your numbers as powers of two and/or use hex:

if( a == 5 )
    val |= 0x1000;

if( b == 20 )
    val |= 0x100;

Cheers,

Ash

PS: Another way of setting and resetting individual bits is to use bit fields. Perhaps they might be more in tune with what you want?

int blo=0;
for(int i=0; i< New.GetLength(); i++ )
	{
		if(isalpha(New.GetAt(i)))
		{
			blo |=0x1000;
			if(isupper(New.GetAt(i))) //Upper case KeyStroke
			blo |= 0x100;
			else
				blo |=0x10; //Lower Case KeyStroke
		}
         }

if i try it with Blood what will give me is 4352 or what i need is 1100 (1000 for being an alpha and 100 for being uppercase¨.

You are confusing base-10 with base-16.
