No the problem is not that the values in the control are not correctly
initialized, moreover that the day-value gets shifted to the left
so it's not visible to the user. If I click on the control and
jump to the left with the cursor the complete value is visible.
But thanks for your suggestion anyway, if you or somebody else
knows another lead I hope to hear it....
Thanks,
mace

I already solved it.
The problem was with the focus. For some reason if I called SetFocus in the OnCreate function of the derived CDateTimeCtrl class I got this problem.
But if I called SetFocus in the derived CListCtrl class which is responsible for creating the control, right after it has been created, it all works fine!
Thanks for the reactions guys, but I am glad that I got it fixed now! 
Take care,
mace

Hi, I'm developping a database application using DAO, and I think it uses version msjet36.dll or something like that.
I took the app on my home pc, and it just stopped working, I checked out and there was only the msjet40.dll installed.
As far as I know, these dlls are dynamically loaded, but are there any compatibility issues?
Regards
Daniel

Hi All,
Is there any sample application without using STL List for addition or deletion?
|
|
|
|
|
Examples of what? And why would you now want to use an STL list, may I ask?
|
|
|
|
|
Hi,
I wrote an application in which, i used lot of structures. Using STL list i push and pop the few same set of structure items. My friends said, STL list makes more weitage, So i decided for alteration. I got the solution now. Gokings thanks for ur effort.
Thanks

Dear all,
i'm struggling since last week trying to find memory leaks in my web application when number of users increases, say 100 or more. We have a web based application which uses some VB as well as VC Com dll's. The InetInfo.exe crashes due to memory leaks caused by these dll's and also by the asp code.
We've used a microsoft application to generate the memory dump of InetInfo.exe
Its called LeakDiag. It generated the dmp file and also some xml logs. We also used microsoft's DmpChk.exe to read the dmp file. This is (text) the contents of the dump file
<br />
RVA 00000BB8, 01000000 - 01006000: 'C:\WINNT\system32\inetsrv\inetinfo.exe'<br />
RVA 00000C24, 77f80000 - 77ffd000: 'C:\WINNT\system32\NTDLL.DLL'<br />
RVA 00000C90, 78000000 - 78046000: 'C:\WINNT\system32\msvcrt.dll'<br />
RVA 00000CFC, 7c570000 - 7c628000: 'C:\WINNT\system32\KERNEL32.DLL'<br />
RVA 00000D68, 7c2d0000 - 7c332000: 'C:\WINNT\system32\ADVAPI32.DLL'<br />
RVA 00000DD4, 77d30000 - 77da1000: 'C:\WINNT\system32\rpcrt4.dll'<br />
RVA 00000E40, 77e10000 - 77e75000: 'C:\WINNT\system32\USER32.DLL'<br />
RVA 00000EAC, 77f40000 - 77f7e000: 'C:\WINNT\system32\GDI32.DLL'<br />
RVA 00000F18, 77a50000 - 77b3f000: 'C:\WINNT\system32\OLE32.DLL'<br />
RVA 00000F84, 6e5a0000 - 6e5c0000: 'C:\WINNT\system32\iisrtl.dll'<br />
...<br />
...<br />
...<br />
These are the lines of text which correspond to our application dll's
<br />
RVA 000039B4, 11000000 - 111b4000: 'C:\Apps\WebCache\WebCache.dll'<br />
RVA 00004518, 04200000 - 04573000: 'C:\Apps\WebCache\Admin.dll'<br />
...<br />
...<br />
But i'm stuck now. I do not know how do i understand and interpret the above data. Is there some other way i can track memory leaks in my dll's and/or web application.
Plz. help.

I always search on 'new' and 'delete'. (in C++ every new has a delete)
but this is not efficient though.
There are programs that do the search for you. I think "Purify" is one of them. (but I'm not sure)
During my studies they always said that you could easily write a garbage collector... ?
good luck.

I'm working with tree view ctrl with MFC and WTL.
What I really want is to get callback message (TVN_GETDISPINFO) into my tree view class and process or modify my tree items.
That's why I set I_CHILDRENCALLBACK to cChildren in TVITEM structure and set TVIF_CHILDREN flag into uFlags somthing when I insert items to tree ctrl..
My GetDispInfo handler look like this..
if(tvitem.mask & TVIF_CHILDREN){
tvitem.cChildren = (/*somecondion is true?%/)? 1: 0;
}
But I doesn't work..
Even though some items have children, button look like [+] didn't appear..but I could expand that..
Very strange, isn't it..?
Does anyone have idea to solve this problem?

Should the next C++ standard include support for "Design by Contract"?
I'm interested in hearing people's oppinions on the subject.

Stroustrup addresses this in D&E and, to sum it up, he feels that enforcing pre/post conditions in the language doesn't work because
a) The person writing the code usually can't predict all usages of the code before hand, so he makes the restrictions too tight
b) Later on, some perfectly valid user of the code runs into a wall with a restriction, and has to relax the restriction
c) After doing that a couple times, people get sick of having to maintain the list of restrictions and just ditch them completely.
If you think this is far-fetched, the exact same thing happened with exception specifications.

It seems to me that exceptions are different than pre/post conditions. Exception specifications are problematic because a sub-function the programmer uses and has no control over can throw an exception that he does not expect. With contracts, the writer is in control of the contracts.
I suppose it is possible for a person to make the restrictions too tight, but in my mind its better to have restrictions that are too tight than those that are too loose (or even non-existent).
The funny thing about the argument you presented is that this same argument applies as well to ASSERTs. Everyone I've talked to and everything I read encourage the use of assertions. In this Q&A session (http://66.102.7.104/search?q=cache:JUm2esOnHs8J:www.research.att.com/~bs/slashdot_interview.html+Stroustrup+assert&hl=en) Stroustrup argues that he prefers asserts and that some assertion templates should even be standardized. He just doesn't think that pre/post conditions add more than asserts can. However, there are people who disagree. Asserts can't be inherited with classes, where as pre/postconditions could.

Hi, all.
I have difficulty when I was trying to get texts from my dialog and show them on the View.
Does here have any examples relating this? I need one as my reference.
Thanks.

Well, GetWindowText gets text from controls or any CWnd/HWND actually. Is you use the GetWindowText that is a member of CWnd then it either fills a text array or a CString. You can them pass those to the View where you wish to show them.
eg.
CString csText;
CEdit m_myEdit;
m_myEdit.GetWindowText(csText);
// pass the string to the view
pMyView->ShowText(csText);

Hello,
I have 6000000 Records in my Bank and,
I want to Add theme in a DataGrid no by
a Repeat statement by setting the Recordset to
it. Like set Datagrid.Datasource="" in VB.
Best Wishes,
Thanks.

hi bosss .. it is not a good idea to go for datagrid and loading all these data into it thru datasource. Ofcourse, ur UI will be stucked for for more than 5 minutes.
Its better u use a flexgrid instad of datagrid and display a minimum of 10 or 20 rfecords at a time. On "next" / "previous" button click load the records accordingly by DB a query.

It seemed simple at first: support DBCS.
OK!
All the DBCS lower 128 characters are ANSI/ASCII; exception of '\' which is the Yen Sign in Japanese Shift-JIS.
BUT!
All the DBCS sets also provide a second set of characters representing: a-z, A-Z and 0-9. In addition some DBCS sets provide a second set of characters representing some other characters that must be recognised.
NOW!
First I made an invalid assumption that the _tcsXXX and ect... could be used to solve this problem, and second that any character represented in ANSI/ASCII set would be in the SBCS character set.
Quesions?
1) Should I provide a mapping a function that reconizes the same chacreter in ANSI and DBCS, and use that for all testing ( a.k.a. if( IsChar(*pChar, _T('-')) ) ).
2) Should I force useres to only use non-language specific characters, if they are aready defined in the ANSI/ASCII set.
Examples:
1) (LOCALE: Japanese Shift-JIS)
"0" and "\x82\x4F" both represent character '0', but _ttoi() does not recognise both of these as character '0'.
2) (LOCALE: Korean)
"+" and "\xA3\xAB" both represent character '+', but both _tcsncmp( pStr, _T("+") ) and *pStr == _T('+') does not recogize both of these as the character '+'.
Conclusion!
This is a pain in the 'BLANK'!
Ultimate Quesions!
1) Is this realy worth the effort?
OR
2) Is this just a ridiculously large amount of overhead to add proper support for DBCS character sets?
Note:
Requirements: support for ASCII, DBCS, UNICODE.
