I'm using the win32 API, so I would like to be able to use the SendMessage Function to change the text in these two controls.
eg:
SendMessage(GetDlgItem(hDlg,IDC_TIMESLIDER),UDM_GETPOS,0,0);
*this code is for getting the position from a slider*
Anyone know where I can find the flag for changing text, or for that matter some decent documentation on this?

Hi,
WSAStartup
Have you linked the following lib file to your project:
Library Use -> Ws2_32.lib : Link WSAStartup[^]
_beginthread
Have you included the following header file to your project:
#include <process.h> /* _beginthread, _endthread */
Link _beginthread[^]

Hi all,
I have created a tab control with 4 tab items.2 tab items are disabled initially.Only the enabled tab items must be focussed when the mouse pointer is placed onto the corresponding enabled tab item.
problem i am facing here is even the disabled tab items are focussed when the mouse pointer is moved onto the corresponding disabled tab item
pls suggest me how to avoid getting focus on the disabled tab item
Thanks,
Sireesha

You could try catching the GetFocus event and setting the focus back to the previously-focused tab.

I seen many examples about ListBox,in DrawItem they use the state and the action to decide how the item should be drawn. I am puzzled that what is difference between focus and the select or selected.Besides,is the whole ListBox redrawn when I click the item when the program are running?Could somebody give details~?
Thanks~

In many controls (like a standard listbox) the focus state and selected state are set at the
same time.
Having both states gives custom controls a way to indicate keyboard focus without an item being selected or vice-versa.

In the standard listbox rendering, Focus typically draws a dashed rect around the "current" item and Selected shows the item in color. The difference is useful if you want to e.g. keep the Selected item highlighted when the listbox is not focused.
Usually only the affected items are redrawn. For example, if you have item 1 selected and click on item 2, you'd get draw messages for item 1 (with the selected flag cleared) and item 2 (with the selected flag set), but no draw msgs for items 0 or 3. If oyu *scroll* the listbox you'll get draw messages for all visible (either partially or fully) items, but not for those items whose rects fall outside (above/below) the window's client area.

Hello friends, this me back with a question. I ve got a code snippet for finding the list of systems in a LAN.It lists the computer name and the IP address. Now i wanted to know how i can find the status of the system ie. if it is active or not.
here is the piece i used to found the systems:
for ( unsigned int i = 0; i < BufferSize/sizeof(NETRESOURCE); i++, NetResource++ )
if ( NetResource->dwUsage == RESOURCEUSAGE_CONTAINER && NetResource->dwType == RESOURCETYPE_ANY )
{
if ( NetResource->lpRemoteName )
{
CString strFullName = NetResource->lpRemoteName;
if ( 0 == strFullName.Left(2).Compare("\\\\") )
strFullName = strFullName.Right(strFullName.GetLength()-2);
gethostname( szHostName, strlen( szHostName ) );
host = gethostbyname(strFullName);
ptr = (struct in_addr *) host->h_addr_list[0];
int a = ptr->S_un.S_un_b.s_b1; // 211.40.35.76 split up like this.
int b = ptr->S_un.S_un_b.s_b2; // 40
int c = ptr->S_un.S_un_b.s_b3; // 35
int d = ptr->S_un.S_un_b.s_b4; // 76
lpszSystemInfo = tchBuffer;
// Get and display the user name.
GetUserName(lpszSystemInfo, &cchBuff);
strTemp.Format("%s --> %d.%d.%d.%d",strFullName,a,b,c,d);
pList->AddString(strTemp);
}
}
}
this is a downloaded code friends. but still i want to know how.if we can find the IP address, then there must be a way to find its status. Pls do let me know if anyone of you know this.Thanks (in anticipation)

(If I understand your question correctly ...)
What about the function:
FILE *_popen(const char *command,const char *mode)
You can uses this function to ping the other machine, and know the status.
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
char psBuffer[128];
FILE *pPipe;
if( (pPipe = _popen( "ping 192.168.0.1", "rt" )) == NULL )
exit( 1 );
while( !feof( pPipe ) )
{
if( fgets( psBuffer, 128, pPipe ) != NULL )
printf( psBuffer );
}
printf( "\nProcess returned %d\n", _pclose( pPipe ) );
}
Hope this helps ..

How did you get your array of NETRESOURCE structs? If an item is in the array then I would assume
it is active. What do you mean by active status?

Hi everybody!
I downloaded a project.When I compiled it, I got an error saying 'Cannot open Iphlpapi.lib'.
Then i downloaded the library file and included it in the project.
Still it shows this error!
I dono what has to be done!
Please help me!
Thanks in advance!

you have to tell the linker where to find the .lib file.
look in your project settings, and reach the linker "additionnal libraries" option...
|
|
|
|
|
Do you have the latest platform SDK installed.
To include a lib file you can also use...
Another option is use #pragma comment( lib, "Iphlpapi.lib" )

Why is that called "comment" any relavance?

From MSDN:
#pragma comment( comment-type [, commentstring] )
Places a comment record into an object file or executable file. The comment-type is one of five predefined identifiers, described below, that specify the type of comment record. The optional commentstring is a string literal that provides additional information for some comment types. Because commentstring is a string literal, it obeys all the rules for string literals with respect to escape characters, embedded quotation marks ("), and concatenation.
lib:
Places a library-search record in the object file. This comment type must be accompanied by a commentstring parameter containing the name (and possibly the path) of the library that you want the linker to search. Since the library name precedes the default library-search records in the object file, the linker searches for this library just as if you had named it on the command line. You can place multiple library-search records in the same source file; each record appears in the object file in the same order in which it is encountered in the source file.

Dear,
I am trying to create a MFC program to scroll some text.
I have already used the double buffering technology, however, there is still some flicker...
I want to do one without any flicker.
Is anyone who can help me???
Thanks a lot.
Here is my code
struct News
{
CString strNews;
int pos;
int initpos;
BOOL bDecrease;
};
CList<news*,news*> m_News;
void CTextScroller::OnTimer(UINT in)
{
if(in == 0)
{
CClientDC dc(this);
CRect rectClient;
GetClientRect(&rectClient);
MoveTextToLeft(&dc, rectClient);
}
CStatic::OnTimer(in);
}
void CTextScroller::MoveTextToLeft(CDC* pDC, CRect& r)
{
int count = m_News.GetCount();
if(!count)
return;
CDC memDC;
memDC.CreateCompatibleDC(pDC);
if(m_BmpMain.m_hObject == NULL)
{
m_BmpMain.CreateCompatibleBitmap( pDC, r.Width(), r.Height() );
}
memDC.SelectObject(&m_BmpMain);
memDC.SelectObject(&m_font);
memDC.SetBkMode(TRANSPARENT);
memDC.SetTextColor(m_TextColor);
News *_news = NULL;
CSize size;
POSITION pos = m_News.GetHeadPosition();
memDC.FillSolidRect(&r,m_BkColor);
while(pos)
{
_news = m_News.GetNext(pos);
if(!_news)
return;
size = memDC.GetTextExtent(_news->strNews);
if(_news->bDecrease)
_news->pos--;
if(_news->pos < r.left - size.cx)
continue;
//memDC.DrawText(_news->strNews,CRect(_news->pos, 0, _news->pos + size.cx, size.cy),DT_LEFT);
memDC.TextOutW(_news->pos, 0, _news->strNews);
}
pDC->BitBlt(0, 0, r.Width(), r.Height(), &memDC, 0, 0, SRCCOPY);
}
