how to set the height of the combo box

Using the resource editor. Since a combobox is two controls acting as one, the sizing for each is separated. Click the edit control to size it, and click the dropdown arrow to size the listbox control.

At design, click over the down arrow of the combo, (the cursor turns in a double arrow), you will see that the bottom selection point of the combo it turns blue, then drag it down to the desire size. Yep, it's something tricky.

but it only expand in size in run time............and does not display the data which i have inserted in it at design time

Yes that's right.
And why you need your data in design time?
You can't do anything with your data at design time. It's just "Design".
What are you trying to do?

I am sending login credentials through ActiveX Control developed in VC++ 6.0 to Server side which is developed in Delphi
//Client side struct in VC++ 6.0
typedef struct
{
char User[41];
char Password[41];
char ClientVersion[41];
char EndCode[2];
}TNetConnectCheck;
//Server side struct in Delphi6
TNetConnectCheck = record
UserName : string[40];
Password : string[40];
ClientVersion : String[40]; // Added by Ravi on : 03/08/2006
EndCode : array[0..1] of Char;
end;
but, I am getting some junk characters in the strings at serverside eg. User name like 'CrazyToLearn#0...#0'
I want to send the packet which is having the length 125 to server with exact 'CrazyToLearn' not with any padding 0 or junk characters.
I tried all the trims dynamic char array but cant solve the problem, Please instant help will be really appriciated...
THANX

Please consider the statement I forgot to mention in the post is : "I dont have to change code at server side,whatever we want to modify , its only at client side"

I'm no Delphinium but as a general approach you need to determine the byte count sizes of the types involved e.g. sizeof(TNetConnectCheck) and make sure they match up. You might also want to control the data type alignment on the client side, see #pragma push pack : 1 (That syntax is wrong so you'll need to search ) or __align your client side data type.
You also need to check whether the string types on the Delphi side are NULL terminated or not and setup the client side data appropriately.
Finally you need to check the calling convention, e.g. __cdecl, __stdcall or Delphi equivalents of the actual call between the two modules and make sure both sides are expecting the same behaviour in terms of stack cleanup. I suspect this last part is already OK or you would not be getting as close as you are but it does no harm to check and be sure you understand what's happening under the hood.
Nothing is exactly what it seems but everything with seems can be unpicked.

Hello all
Is there any functionality by which we can know the sizeof the graphics memory?
Thanks in advance

hi...
i have to use memorystream in mfc.
should i add any header fiile?'
other wise what is the procedure?
can anyone help me?
paulraj

I don't remember any MFC class called memorystream.
Maybe a compination of CArchive and CMemFile?
And any MFC project has enough header information in it to use those.
Beyond that, I can't help.

It was jigsaw game app, and I wanted to be able to load jpgs, bmps, gifs, tifs, pngs, etc.
Looking at my code now, I'm a little unsure of casting the result from CoTaskMemAlloc to an HGLOBAL, but it seemed to work fine!
Anyway, take what you can, and avoid any bad habits.
Iain.
HBITMAP CJigSawDoc::JigLoadPicture (CFile *f, CSize szImage)
{
IPicture *iPic = NULL;
DWORD dwFileSize, dwRead;
dwFileSize = f->GetLength ();
void *pBuffer = ::CoTaskMemAlloc (dwFileSize);
if (NULL == pBuffer)
return NULL;
dwRead = f->Read (pBuffer, dwFileSize);
if (dwRead != dwFileSize)
return NULL;
IStream *iStream = NULL;
if (FAILED(::CreateStreamOnHGlobal ((HGLOBAL)pBuffer, FALSE, &iStream)))
return NULL;
::OleLoadPicture(iStream, 0, FALSE, IID_IPicture, (LPVOID*)&iPic);
iStream->Release ();
::CoTaskMemFree (pBuffer);
if (iPic == NULL)
return NULL;
CWindowDC dc (CWnd::FromHandle (::GetDesktopWindow ()));
HBITMAP hBitmap = NULL, hOldBitmap = NULL;
HDC hMemDC = CreateCompatibleDC (dc);
CSize pxSz, hmSz, szScreen (::GetSystemMetrics (SM_CXFULLSCREEN), ::GetSystemMetrics (SM_CYFULLSCREEN));
iPic->get_Width (&hmSz.cx);
iPic->get_Height(&hmSz.cy);
AtlHiMetricToPixel(&hmSz, &pxSz);
szScreen.cx = (int)Interpolate (0, szScreen.cx, 0.9, 1.0);
szScreen.cy = (int)Interpolate (0, szScreen.cy, 0.9, 1.0);
if (pxSz.cx > szScreen.cx)
{
pxSz.cy = (int)Interpolate (0, pxSz.cy, szScreen.cx, pxSz.cx);
pxSz.cx = szScreen.cx;
}
if (pxSz.cy > szScreen.cy)
{
pxSz.cx = (int)Interpolate (0, pxSz.cx, szScreen.cy, pxSz.cy);
pxSz.cy = szScreen.cy;
}
hBitmap = ::CreateCompatibleBitmap (dc, pxSz.cx, pxSz.cy);
hOldBitmap = (HBITMAP) SelectObject (hMemDC, hBitmap);
iPic->Render (hMemDC, 0,pxSz.cy - 1, pxSz.cx, -pxSz.cy, 0,0, hmSz.cx, hmSz.cy, NULL);
iPic->Release ();
iPic = NULL;
SelectObject (hMemDC, hOldBitmap);
return hBitmap;
}

fstream ?, fstream fs("Image.img", ios::in ...); makes file to stream.
if you want to keep in memory, as Iain already specified, use CMemFile() to store image data and CArchive provides the redirection stream like operators (<< , >>)

thanks for your reply.
should i use any header file?
paulraj
|
|
|
|

#include <fstream> for fstream class.
And if you are using MFC, CMemFile, CArchive don't require additional header i think.
I am unsure, that you are refering stream as in C++ iostream programming, it seems.

In addition to the other replies...
CMemFile is a memory stream. You can use it without using CArchive.
Just create A CMemFile object, open the image file (binary mode), read chunks of bytes from
the image file and write them to the CMemFile. When you're done you can detach the
BYTE array from the CMemfile if you need to.
CMemFile is declared through afx.h, which you should have included already.
