I'm trying to come up with a way to have a popup come up when my edit box receives focus.

I've tried the OnFocus, but there were problems with that.

What I want is a soft-keypad to come up so the user and input data.

Any ideas.

Thanks in advance.

Jim

Use some kind of static boolean flag variable in OnFocus handler and don't allow renentry into code which opens keypad.

I see that this is probably the only way with an edit box. But I think there will be a problem of the focus staying on the edit box and the dialog coming up when the window looses then recieves focus will the "cursor" is still in the box.

Is there a command to move the focus to another "safe" place?

just set focus to another field when the dialog closes?

CEdit* pNextField = (CEdit*)GetDlgItem(IDC_ANOTHERITEM);
pNextField->SetFocus();

Well, if it's modal and invisible your UI will be effectively frozen. Why do you want to do this?

In the properties of dialog change the 'visible' property to false.Then add the bool variable to your class.Lets name it m_bFirstShowWindow and in constructor make it true.Then overriden OnWindowPosChanging and put this code in it:

void CYourDlg::OnWindowPosChanging(WINDOWPOS* lpwndpos)
{
	CDialog::OnWindowPosChanging(lpwndpos);

	if(lpwndpos->flags&SWP_SHOWWINDOW)
	{
		if(m_bFirstShowWindow)
		{
			m_bFirstShowWindow=FALSE;            
			lpwndpos->flags&=~SWP_SHOWWINDOW;        
		}
    }
}

Hello all,

I was reading here at CP about WndTabs and I've try to download it for several days now from www.wndtabs.com but the site doesn't seem to work. Does anybody knows anything about the status of wndtabs.com site or is there any other place where I can download it?

TIA,
Thomas

Fellow Elites:

Confused | :confused:

I use MFC created a explorer style SDI, leftside is CLeftView and I add a TreeView to it. On the right hand side I got CHtmlView.

So the problem is that when I double click on one of the Tree Item, the right hand side should load a new HTML Page, using Naviagte2 or LoadFromResouce to do it.

So can any one tell me how to do that?

Thanks in Advance.

__based

I want to create a struct like this:

typedef struct tagSomeStruct
{
   unsigned char * basePointer;
   char __based(basePointer) * aBasedStringPointer;
}
SomeStruct;

I KNOW that this will not compile (basePointer must be defined outside the struct).
But if anybody knows a trick to base a pointer in a struct on another pointer in the same struct, then, pretty please, share your knowledge.

For the curious: I'm toying with a tool to serialize C collections, and it is crucial for the reusability that the basepointer can be defined dynamically.

Are you using C?
I am not sure that I understand your question, but can you accomplish this by adding a constructor to your struct if you are using C++?

Yes I am using C, but maybe I should switch to C++ for this task then.
You say that a constructor would solve this, but the problem is that I can't define a pointer to be based on a member in the same struct/class, I don't see how a constructor can help here?.

I have a program that keeps getting a user breakpoint in ntdll. The program works perfectly, it's just this breakpoint is very irritating. Is there any to disable these breakpoints?

These user breakpoints in NTDLL are usually as a result of problems with your application. Check the output window; you may be corrupting memory in some way (double deletions, etc.)

Displaying 2 BMPs at the same position

GUEJO4-Jun-02 1:26

Hello

I'm kinda newbie in C++ and I'd like to display 2 bitmaps at the same position, or clearlier, one above another.

I loaded the bitmaps in the resources (I'm using VC++ 6.0) and I then had their IDs. Frown | :(

I added a picture control and used the classwizard to get a CStatic variable associated to the picture control (it's actually a CStatic one) Hmmm | :|

Now I try to display these bitmaps in function of the resolution so I must use SetWindowPos to set properly the size, the position and the Z-order (the depth).
The problem comes from the fact that however I try, it's always the wrong BMP that is over the other, hiding it. Confused | :confused:

If anyone could help me, it would be very nice Rose | [Rose]

Are you sure that you are using SetWindowPos properly to set the ZOrder of your static controls?

Actually I've done a lot of combinations :
first.SetWindowPos(&wndTop,...);
second.SetWindowPos(&wndTop,...);
or with the SWP_NOZORDER flagat the end
I also tried to initialise in a different way which is first set the second then the first and it was the same result.
I finally tried to change the tab order and it worked !!!
But what I'm trying is to do the same with the CxSkinButton furnished here, on this site and it does not work as well as I wanted (By the way it is a great code)

sorry I do not have time to explain more in details, I will continue tomorrow...

I am not usre what wndTop is in your example, but what you would do is call SetWindowPos on the static control that you want to be placed on top, and you would place the handle of the bottom control in the hwndAFter parameter of the function.

You will only need to call this function once to set the order that you are interested in.
