It makes sense from time to time. Just don't abuse it.
It just that, a warning (not an error). The programmer goes and scrutinizes the code and makes a decision. If they deem the existing code sound, then disabling the warning for that specific chunk of code makes perfect sense.
Make sure to turn the warning back on after the section of code in question that has been deemed by the programmer as fine. That way every future warning will need to be scrutinized by the programmer and they get to decide if it's a false alram or not.
#pragma warning (disable: XXXX)
// Some code that is deemed OK after reviewing warnings
#pragma warning (default: XXXX)

You can also use /wdn in project settings.
Project | Properties | C/C++ | Command Line
Disables the specified compiler warning where n is the compiler warning number.
For example, /wd4326 disables compiler warning C4326.
Please refer here[^] for more information.

You are correct Cedric. 
As per MSDN[^] "Treats all compiler warnings as errors. For a new project, it may be best to use /WX in all compilations; resolving all warnings will ensure the fewest possible hard-to-find code defects."

hi
i am on my pc on LAN and i woud like to make an application to reteive Data from a database located on the server of the LAN.
i am programming with MFC,and i use the class CRecordset,and the method conssit to access to the database from ODBC (with ingres DATABASE), but when i add the the new class (MFC ODBC Consumer),i can't got the tables of the database(because when database is located on same PC,the ODBC give u the hand to show him the path of the database and the table that i would like to work with).
can you help me ?

The application does not need to know the location of the database it is accessing, that's what the DSN is for. Reconfigure your DSN so that it "points to" the correct location of the database. Then when you create your CRecordset object, reference the correct DSN.

Your code is almost unreadable, see point 5 here[^].
You should also replace the < and > characters by the symbols that are just above the emoticons otherwise they will be eaten (and for template, that will be quite difficult to understand).
And please, post the exact error message.

Why did you not preview your post prior to submitting it? Had you done so, you would have noticed a lot of important code has been hidden (it's not actually removed). Modify your post and surround the code with <pre> tags, and use the < above the smileys instead of the actual < character.
With one small change, your code compiled fine for me.

Which means nothing out of context.
My guess is the following line is in error:

I added WM_CTLCOLOR and coded the following lines in it.
HBRUSH DlgTest::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hBrush = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (pWnd->GetDlgCtrlID() == IDC_CHECK1)
{
pDC->SetTextColor(m_checkBoxColor);
pDC->SetBkMode(TRANSPARENT);
}
return(hBrush);
}
and in onInitdialog i added the following lines
m_checkBoxColor = RGB(255,255,255);
GetDlgItem(IDC_CHECK1)->Invalidate();
where m_checkBoxColor is COLORREF variable.
This works fine when XP themes service off. When it is on it is not working. How to make it work when themes service is on

Thanks for your reply but i want to access the contents of the history folder.How can i do it?
|
|
|
|
|
FindFirstUrlCacheEntry("visited:",...) and FindNextUrlCacheEntry(...)
|
|
|
|
|

Try using SHGetFolderLocation and CSIDL_HISTORY.

I have used the FindFirstUrlCacheEntry("visited:",...) and FindNextUrlCacheEntry(...) functions to display the history in my application.But,some times the history which i display is different form the history which is displayed in the explorer(Ctrl+h).What i came to know is that the above two functions access contents from "Internet Cache's index.dat located at %userprofile%\Local Settings\Temporary Internet Files\Content.IE5".But the history which is displayed in the explorer when we press Ctrl+h key word will be accessed from "Internet History's index.dat located at %userprofile%\Local Settings\History\History.IE5".so,to maintain unifromity in my application i want to extract the contents of "History.IE5" folder.But i am not able to access data form it.Can any one help me out in this ?
Thanks.

Yes, assuming you have permission. Just access the contents like you would any other folder.
