You can either dynamically create and destroy a new window or you can pre-create a window and keep it hidden to show when the time comes.

In a dialog, some edit controls become read only / normal at runtime based on some conditions.
When the edit is read only, I want to avoid focus to control.
When tab pressed I want to set focus to next editable control.
On Mouse click, focus should be in previous control only.
To do this what message should I handle?
I have DDXed edit controls to customized CEdit derived class.
Thanks

In Style of CEdit, u have Tab Stop. please uncheck Tab stop.

You have to remove the WS_TABSTOP style at runtime.
You could do this at the same time you're making the control read only.
Use CWnd::ModifyStyle[^] like edit.ModifyStyle(WS_TABSTOP, 0);

It better to do tab stop at run time than doing statically.
Initially we can set the tab stop to 0 using the resource, but runtime changing is more useful as superman suggested. Full 5 for the answer

here is the source code of create a bitmap from memory dc,
CRect rRect;
GetClientRect(rRect);
CDC *pDC = GetDC();

CBitmap *pOldBMP = NULL;
MemDC.CreateCompatibleDC(pDC);

ASSERT( rCaption.Height() >= 0 );
if (rCaption.Height() < 16)
rCaption.bottom = rCaption.top + 16;
rCaption.right += 25;
if (rRect.Width() >= 16 && rCaption.Width() > rRect.Width() - 16)
rCaption.right = rCaption.left + rRect.Width() - 16;

// clear all alpha channel data

while (iLines-- > 0)
{
LPDWORD pdwPixel = (LPDWORD)pLine;
for (int x = 0; x < bmMem.bmWidth; x++)

}

free(pPixels);

rCaption.left += 22;
MemDC.SetTextColor(RGB(0, 125, 0));
MemDC.DrawText(m_strText, rCaption, DT_SINGLELINE | DT_LEFT | DT_END_ELLIPSIS);
ReleaseDC(pDC);
=========
can someone explain the functionality of this sentence:
*pdwPixel++ &= 0x00FFFFFF;
why did need this??
thanks in advance...

This line clears the alpha channel of the pixel (leaving RGB values untouched).

Is this the right way to do it... I am getting an complier error ..(type mismatch)
struct {
char flag,
unsigned char data[60],
}packet;
vector<unsigned char=""> vect_data;
int func(packet *p_packet)
{
vector.push_back(p_packet->data);
}
I think I am dng somehting horribly wrong can anyone help me to figure out whr I am wrong..... I want to store all the data in vector as data arrives....
Can I use vect instead of data array... ? and than pass vect to vect..if so can thn when I copy structure will vect data filled...or I have push the data.... Also does vect works eactly like array....?
Plz help
Thanks!!!

If what you're trying to do is store strings in a vector, here is what you have to do.
struct {
char flag,
unsigned char data[60],
}packet;
vector<string> vect_data;
int func(packet *p_packet)
{
vector.push_back(p_packet->data);
}

As superman said,
u need to use vector <string>. please change the structure as
syntax of structure defintion is wrong in your case so change as below
along with that, change the structure data as string to hold string data
struct
{
char flag;
string data;
}packet;
// There is no problem using vector, if u want sequence access to the data.
vector<<string>> vect_data;
int func(packet* pPacketData )
{
vector.push_back( pPacketData->data );
}

I recently converted a project from VC++6 to Visual Studio 2008. The project is an unmanaged DLL using MFC.
The problem I'm having is, when I run the project using Excel, using a tester I made to call the DLL and check return values, when the DLL should return false or true, based on certain calculations and conditions, the VS2008 project always returns true. Even using a "return false;" statement, the Excel tester gets a return value of true. In VC++6 it worked fine. Has anyone else seen this, or know of a way to fix it, or test futher to find the cause? Many Thanks!

Have you tried debugging the DLL from within Visual Studio (most likely by attaching to the tester, if it's a process, or Excel, if it's hosting the tester library) and seeing exactly what's going on behind the scenes?

Is it returning a BOOL or a bool? I'll wager the DLL returns a bool (a one byte value), but Excel is looking at the value as an int (a 4 byte value.)
(The reason it may have "broken" is simply due to how the code was compiled between the two compilers since I've seen VC++ 6 display this behavior.)

To the first question, yes, that is why I built the Excel tester. That's how I know the 'return false;' statement does nothing.
To the second question, I actually have several DLLs that return in the same way, and some of them still work, while some of them get stuck returning true. On the BOOL vs bool, in the C++ code it's a 'bool' and in the tester it's looking for a VBA 'Boolean'. Though with some of the DLLs working correctly, and the others not, I don't think that has anything to do with the bug.

I can't totally confirm this, but some sources state that a VBA Boolean is 4 bytes (another said it was 2 bytes).
|
|
|
|
|
Using Len() and LenB() in VBA, the size of a Boolean is 2 bytes. Here[^] it says the size of a C++ bool is 1 byte. For my problem, I can just return an int, 1 or 0, instead of true/false, and get around it. But Why would the size difference between bools cause this problem?
