Hi all,
I like to create a kind of digital clock as an ocx. therefore other programmer can use my ocx inside their program. problem is:
1. How can i set up the timer for an ocx?
Note: I have create a WM_CREATE message handler and put the SetTimer command in it. Then I Create a WM_TIMER message handler and put the increment of the "second" in it, and display the number inside the OnDraw. But, it seems that the WM_TIMER message handler is never been called (that make my "Second" number never changed)
2. Is it possible to use a dialog box for an ocx, or do I have to always use OnDraw to draw something inside the ocx?
Below is the code that mimic the functionality of my digital clock. I use a data member called m_number that has been set to 0 inside the CxxxCtrl constructor. I expect to have this number increased each second elapsed. But it just didn't work. Any help please. Thanks.
// CTimerOcxCtrl::OnDraw - Drawing function
void CTimerOcxCtrl::OnDraw(
CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
// TODO: Replace the following code with your own drawing code.
CRect rectOcx = rcBounds;
CString strNumber;
strNumber.Format("%ld", m_number);
pdc->DrawText(strNumber, rectOcx, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
}
/////////////////////////////////////////////////////////////////////////////
// CTimerOcxCtrl message handlers
void CTimerOcxCtrl::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
m_number ++;
if (m_number > 100)
m_number = 0;
COleControl::OnTimer(nIDEvent);
}
int CTimerOcxCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (COleControl::OnCreate(lpCreateStruct) == -1)
return -1;
// TODO: Add your specialized creation code here
/*
CWnd *pMainWnd = AfxGetMainWnd();
HWND hWnd = pMainWnd->GetSafeHwnd();
*/
//SetTimer(hWnd, ID_TIMER1, 100, NULL);
SetTimer(ID_TIMER1, 100,NULL);
return 0;
}

its possible..
in the CTimerOcxCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
funtion u can create a child dialog. It will be displayed when the ocx is inserted.

I think you need to invalidate or redraw the window on each WM_TIMER message. In your OnTimer handler, before returning you should try one of this:
InvalidateControl(NULL, FALSE);
or
InvalidateControl(NULL, TRUE);
or
Invalidate(FALSE);
or
Invalidate(TRUE);
or
RedrawWindow(NULL, NULL, RDW_UPDATENOW);
or
RedrawWindow(NULL, NULL, RDW_UPDATENOW | RDW_ERASENOW);
or other appropriate.
Hope it helps.

Dear Sir,
this is like A declare my Command :
CCommand<caccessor<cdboficag2accessor> >table;
when i do table.MoveNext() all is good but when I write table.Moveprev() it can't work.
I am using Visual c++ 6.0.
What to do.

Make sure that you havent opened the cusrsor set as forwardonly. Double chk how you opened the table.
cheers...milton.

Can you show me how to open table not fordwarding

What doesn't work with it? Is the compiler/linker complaining? Is an exception thrown? Please elaborate on the "error."

No error, but the moving previous to the record back is not done. That my complain
|

Have you stepped into the method to see what condition is prohibiting the movement?

I don't understand what happens because when I do MoveFirst() I go to the next record, but why when i do MovePrev it does n't go back. That's my complain
|
|
|
|
|
Hence my suggestion to step into the MovePrev() call to see what is actually happening.

Hello!
I hope someone can help with this stuff.
I tried to set up a sample webservice/client stuff, the service is the default c# helloworld service which comes with the ide, the client is a simple c++ mfc app.
I followed the tutorials on msdn to create and deploy the service, which worked fine.
Then i followed the instructions on how to create a client, add web resource etc.
The problem is, that when i try to run the client from my system (windows 2000 sp4) it fails before even starting, saying:
"The procedure entry point getaddrinfo could not be located in the dynamic link library WS2_32.dll."
It runs finely on windows 2003 though.
I googled around a bit for the cause of this problem, but i couldn't find any solutions for win 2000, only xp or 2003.
I checked the 2003 and 2000 ws2_32.dll-s with depends, and in the 2000 version i didn't find the mentioned function. Why does my compiler include references to a function not in my dll?
If anyone can help me to solve this problem, please post a reply.

Messagebox caption will change automatically according to the OS default language. You can use custom messagebox ur own to change the language.

More level of customization can be done by using a windowshook for WH_CBT and traping the HCBT_ACTIVATE.

I think that you can use MessageBoxIndirect(...) to specify a different Language ID to use for the text on the standard button(s).
It looks like MessageBoxEx(...) can be used, but I do not think the "cross-language" functionality is implemented in it.

Does any body a way to remote access a computer on a network to add/remove files.
I know using 'CreateFile()' I can create file on the network but that requires me to login on the local computer with the same username and password as registered on the remote computer. Is there any way to create a token to use for accessing remote computers?
|
|
|
|
|
Take a look at WNetAddConnection2 and its related functions.
|
|
|
|
|
You can use LogonUser() and ImpersonateLoggedonUser() to get access to a remote machine for a specific user with username and password.

After googling little bit I found out two different meanings for Alt Gr.
Does it mean Alternate German or Alt Grpahics or Alt group?
Also how to trap in PreTranslateMessage()? Is this the correct way or is there any better way?
<br />
bool bAltGrp = false;<br />
if((::GetKeyState(VK_CONTROL) & 0x8000) && (::GetKeyState(VK_LMENU) & 0x8000))<br />
{<br />
bAltGrp = true;<br />
}<br />
else if(::GetKeyState(VK_RMENU) & 0x8000)
{<br />
bAltGrp = true;<br />
}<br />
Thanks and Regards,

Hi
I needed to develop HTTP listener in C++. This listener should support SSL. After searching for the technology for this I chose HTTP API which seems to support SSL. First I developed all the functionality of the listener and added request handlers. So now HTTP works well.
I started to add SSL support. Step-by-step I did all the recommendations found in MSDN: added certificate to the store with HttpSetServiceConfiguration (checked with httpcfg - it is there), and changed scheme in URLs to "https".
And... HTTPS does not work. I have absolutely no idea why. I even do not have an idea how to get know why. There are no errors (no errors even in HTTP API logs). HTTP Requests are not accepted. Port is opened but when I try to send data server just disconnects. The requests is not received by the service. Seems like it is rejected inside HTTP API.
Please help! How can I get this work? How, at least, I can get the reason why it does not work?
Thanks,
Andriy

I feel I have to answer your question, since noone else does.
I know nothing about HTTP API, but if it doesn't work, maybe you could use OpenSSL for the https sessions?
That solution is used in one of the programs I'm responsible for maintaining. (I didn't write it, though). Works well.
It uses winsock for http sessions and OpenSSL for https.

To use winsock + OpenSSL i need to rewrite almost all code. I'm not sure that this is acceptable way out.
