Or The activex is not registered or you forgot to add AfxOleInit() in the InitInstance of your project....

First you need to use CRichEditCtrl::SetSel and select the text or character that you need to delete, then CRichEditCtrl::ReplaceSel replazing your selection for "" and ready Green Alien | [Alien]

Changing dialog size

i have a dialog that looks like this:

+-------------+
| +---------+ |
| |    A    | |
| +---------+ |
|             |
| +---------+ |
| |    B    | |
| +---------+ |
+-------------+

A and B are static frames that may hold other controls.

i want to be able to dynamically resize it so that it is either just big enough to hold the "A" rectangle or big enough to hold both A and B. to keep it easy, the width never changes.

so, what's the secret to getting the height correct? i'm doing this:

CRect dispRect;
m_dispBox.GetWindowRect(dispRect);
ScreenToClient(dispRect);
dispRect.NormalizeRect();

CRect normalRect;
m_normalFrame.GetWindowRect(normalRect);
ScreenToClient(normalRect);
normalRect.NormalizeRect();

int w = normalRect.left + normalRect.Width() + GetSystemMetrics(SM_CXDLGFRAME) * 2;
int h = normalRect.top + normalRect.Height() + GetSystemMetrics(SM_CYDLGFRAME) * 2;
	
if (bShow) 
{
      h += dispRect.Height();
      h += (dispRect.top - normalRect.bottom); // space between them...
}

SetWindowPos(&wndTop, 0,0, w, h, SWP_NOMOVE | SWP_NOZORDER);

but the dialog is just a little bit too small to hold the bottom frame. - the bottom frame's bottom is clipped.

I prefer to use GetWindowPlacement and SetWindowPlacement when I work with resize of controls...

but how do you get the dimensions correct?

With GetClientRect() you get the dimension of the client rect.
I prefer to use GetWindowPlacemente because it has the rcNormalPosition member in the WINDOWPLACEMENT struct, when I change the size of each control I use SetWindowPlacement..... Try this

Changing the size of the window?

i think i found it... if i add the height of the caption bar to the rect height, everything fits nicely.

Hi all, I have a small crappy problem. When I load a bitmap I retrieve its width and height, and I want to make the screen view the exact same size. However, I also want to prevent the frame being resized over this size, and so I have managed to implement a system which takes care of it. However, all of the code is situated in the Child Frame class, where the maximum tracking sizes are specified. I then go on to use SetWindowRect(). The problem I get though, is that when using SetWindowRect() the whole width of the window AND frame is set the bitmap dimensions, which means part of the bitmap is obsured by the frame. I have implemented my own offset (to account for the frame), and it works on my computer (or any other with a 19inch monitor), the trouble is I have to demo my app on the computers in Uni, and their monitors are 15inches (and I run XP, they run win2k which means the border sizes are different too), which means the frame will be out of sync with the image (I have tested this). Anyway, how could I get it to set the window and view to the right size? Can I obtain a border offset value? or is there a better way of achieving what I want?

Cheers all,
Alan.

Try adjust the rectangle using "AdjustWindowRectEx".

Anyone know where I can find it?

For editable items, handle LVN_BEGINLABELEDIT. For checks, set the LVS_EX_CHECKBOXES extended list style.

Rewind in a serialize process?

José Luis Sogorb11-Dec-01 4:40

11-Dec-01 4:40

When we are extracting data with serialize( ar >> some_variable >> another_one >> etc. ) is it possible to 'rewind' and begin again, for instance, if we don´t find a desired value?

Ravi Bhavnani11-Dec-01 4:45

Yes. But you should destruct the file's CArchive before rewinding the CFile, and create a new CArchive after rewinding. This will ensure the archive's data integrity.

Thanks.
So, how could I do it in this small sample code:

void CMeteoGraficaDoc::Serialize(CArchive& ar)
{
CDocument::Serialize(ar);
if (ar.IsStoring())
{
ar<<datosF.dia<<datosF.mes;
}
else
{
ar>>datosF.dia>>datosF.mes;
// if (datosF.dia != some_value) ...... rewind and begin to serialize.
}
}

Hmmm, I must have been brain dead when I posted my earlier reply. You can rewind the file during serialization.

void CMeteoGraficaDoc::Serialize(CArchive& ar)
{
  CDocument::Serialize(ar);
  if (ar.IsStoring()) { 
    ar<<datosF.dia<<datosF.mes;
  } 
  else {
    ar >> datosF.dia>>datosF.mes;
    if (datosF.dia != some_value) {
       CFile* pFile = ar.GetFile();
       ASSERT (pFile != NULL);
       pFile->SeekToBegin();          // rewind
       ar >> datosF.dia>>datosF.mes;  // retry
    }
  }
}
