Ok I have found this function aswell:

LONG CompareFileTime(
  const FILETIME* lpFileTime1,
  const FILETIME* lpFileTime2
);

So I have tried it like this, without success Can asnyone please help me (THANKS Smile | :)

char dateCreated[20]; //date time gets assigned
FILETIME ftCreate;
if (!GetFileTime(hFile, &ftCreate, &ftAccess, &ftWrite))
  return;
if (CompareFileTime((FILETIME*)dateCreated, &ftCreate)==0)
{
 ...
}

The first argument should be a pointer to a FILETIME structure. You have a char that has been cast to such.

This will work:

wsprintf(lpszString, "%02d/%02d/%d  %02d:%02d:%02d",stCreate.wYear, stCreate.wMonth,
stCreate.wDay,stCreate.wHour, stCreate.wMinute, stCreate.wSecond);
if (strcmp(dateCreated, lpszString)==0)
{
...
}

If you are simply wanting to know if two SYSTEMTIME structures are equal, why not just use memcmp()?

Don't know ... haven't though of that, but the strcmp is working fine, unless you for see a problem?

No problem, other than an unnecessary call to wsprintf().

How does one convert SYSTEMTIME to char *

memcpy i.e.

char *charMem = new char[sizeof(SYSTEMTIME)];
memcpy(charMem,sysTime,sizeof(SYSTEMTIME));

Owner Draw button changes the tab order

BlrBoy11-Jun-07 2:38

11-Jun-07 2:38

Hello All,

In my dialog box, I want to use an image on a button, so I made it as Owner Draw, I use CBitmapButton class and it is working fine. But when ever the dialog comes up, the initial focus is on the user defined button only. Here is the code for bitmap button

CBitmap bmp;<br />
BITMAP bm;<br />
bmp.LoadBitmap (IDB_ENABLE_BMP);<br />
bmp.GetBitmap (&bm);<br />
m_oMyBtn.SetWindowPos (NULL, 0, 0, bm.bmWidth, bm.bmHeight, SWP_NOMOVE | SWP_NOOWNERZORDER);<br />
m_oMyBtn.LoadBitmaps (IDB_ENABLE_BMP, IDB_SEL_BMP, IDB_FOCUS_BMP, IDB_DISABLE_BMP);

I found when ever I use "SetWindowPos" the initial focus is always on the owner draw button. If I remove "SetWindowPos" function then the focus is as per my tab order settings.

My idea is to resize the button as per the image size. If any other way to do that let me know.

Thanks for your time
BlrBoy

Hi BlrBoy,

Try using SWP_NOZORDER in your SetWindowPos function. This retains the Z-order of the control.

Hope that helps.

Hi Paritha,

Here is a sample code:

<br />
CMenu menu;<br />
menu.CreatePopupMenu();<br />
<br />
menu.AppendMenu(MF_STRING, 10, "item 1");<br />
<br />
CPoint pt;<br />
GetCursorPos(&pt);<br />
<br />
//Now, create the submenu<br />
CMenu menu1;<br />
menu1.CreatePopupMenu();<br />
menu1.AppendMenu(MF_STRING, 11, "Item 1 in submenu1");<br />
<br />
//attach the submenu to main menu<br />
menu.AppendMenu(MF_POPUP, (UINT_PTR)menu1.m_hMenu, "Submenu1");<br />
menu.TrackPopupMenu(TPM_RETURNCMD, pt.x, pt.y, this);<br />

Hope that helps.

Hello,

Thanks for your replies
And the code given by kiran did not work for me because I already have a menu with 3 menu options and now I want one of the menu options to have a popup menu attached to it which earlier was MF_STRING.
CMenu M;
M.CreateMenu
M.AppendMenu(MF_STRING, id_DAta, "Data");
M.AppendMenu(MF_STRING, id_Edit, "Edit");
M.AppendMenu(MF_STRING, id_Model, "Model");

Now the above works.
How should I have popup menu like the following attached to Data. I do not want to add to the 3 menu options above
CMenu M1;
M1.CreatePopupMenu
M1.AppendMenu(MF_STRING, id_Data1, "Data1");
M1.AppendMenu(MF_STRING, id_Data2, "Data2");
M1.AppendMenu(MF_STRING, id_Data3, "Data3");

Thanks

how to set the highest priority to socket program.

Why do you think you want to boost the priority? Suspicious | :suss:

Chances are that the error you're trying to "correct" by tweaking the priorities is a design flaw.
Tweaking the priorities of threads and processes is almost always wrong, or at least the wrong tool for the job. Don't mistake Windows for a real-time OS.
When you write it like that, I read it like "how can I disguise my error to make it even harder to track down". Wink | ;)

What seems to be the most common mistakes when developing socket applications are...

CSocket is used without the developer knowing that CSocket is a blocking implementation. Converting to CAsyncSocket is usually the medicine for this.
CSocket and/or CAsyncSocket is used in a multithreaded application and worker threads are used instead of UI-threads. The threads that the sockets reside in have to pump messages and thus must be UI-threads.

See here[^] to get some more ideas.

If you neither find this post nor the link above helpful, post again and describe what you're trying to accomplish and what you've done so far. Especially if you still think you need to tweak the priorities of your process and its threads.

Another alternative to Roger's excellent suggestions.

Use Winsock directly instead of using the wrapper classes. Then you can implement an event-
driven model instead of using window messages for asynchronous socket communication. Then
you don't need UI threads.

With Win32 function ::GetDC(NULL) you can get the handle of the screen DC.

Hi,
Always draw on OnDraw(), and / or OnPaint() (MFC).
From Outside these function call RedrawWindow() to update.

It depends on what you need a DC for (what you want to draw on).

A DC is a "device context". It represents the drawing attributes of a device.

If you need a DC to draw in the client area of a window you can use GetDC();

If you want to be able to draw on an entire window (not just the client are) there's GetWindowDC().

To draw anywhere on the screen, either of the above can be used to obtain a screen DC.

For non-screen-related devices there's CreateDC()

For drawing to memory there's CreateCompatibleDC();
