Someone may problem me completely wrong 
I think I've heard somewhere that you can't have a default button owner drawn, so in the owner drawn code you have to implement your own flag fo displaying a think line around it. Then to make it act as a default button, (  ) play with the tab order.

Thanks for your input.
It looks like thats how I'm going to have to do it

Hi Derek,
If you can wait a few days for this, I'm writing an article on how to solve this problem, that is how to enable default state for an owner-draw button.
I wrote 1/2 article, so please be patient.

So far I've implemented it as a separate function call in the class, which provides access to a boolean data member.
I'll be interested to read your article.

I need to convert a double to a string, because i want to use setwindowtext, but i don't know we could use ecvt(), or fcvt(). How do they work?
thanks.

There's plenty of examples on the web & msdn.
int sign=0, decimal=0;
double dval=9999.9999;
char* str;
str = _ecvt(dval, 10, &sign, &decimal);
Easy way.
char buf[21]={0x00};
double dValue = 9.9;
sprintf(buf,"%.2f",dValue);
Only thing to watch is the precision with formatting strings.

I have created a Dialog box app. All my processing is in ***dlg.cpp.
The app runs fine except for ... The window does not refresh. I have to move the
mouse over the app to refresh the window.
I have tried ShowWindow(SW_SHOW) and UpdateData(FALSE) to no avail.
Please Help.
Thanx
Leezo

Neither of these force a paint mesage. When you change your data, call Invalidate(false) to force a redraw without erasing the dialog first. Get rid of false to make it also erase.

I'm using ADO to do a connection with Access database. I have a dlgbox with editbox which are linked to this app. When i do the loop:while(!pRs->EndOfFile)
{
if(m_dlglDate==rs.m_ch_RateDate)
{....}
I would like to return value in an editbox when my test "if" succeeded, so how could i do that?
thanks in advance

Do you mean, just pass a value into the editbox field?
if so,I just use DDX &
m_EditControl.SetWindowText("VALUE");
or
SetDlgItemText(IDC_EDIT1,"VALUE");

|

yes, exactly, if i could find the value in the database i want to return it in the editbox, but it could be a COleDateTime or a double, so i believe that setwindowtext return string. How could i return a double value or a COleDateTime value in editbox?
|
|
|
|
|
There are plenty of ways to convert a double to a string.
Function _ecvt for one. double to string pointer.
As for COleDateTime,
COleDateTime x(1999, 3, 19, 22, 15, 0);
CString str = x.Format(_T("%A, %B %d, %Y"));
m_EditBox.SetWindowText(str);
Hope this helps....
Gerry.

Hi All,
I have a query regarding MS Access Database.I am creating a Database & a table in it .I add the Records to the table.The size of teh Database mdb file is increasing as I add the record.But, when I deleted all the REcords in the table in Database, the size of the Database remained the same(as before deletion of REcords).Why is it so ?I am using ADOX to add the Records & the same to delete the Records .
How can I overcome this problem ?
Does in MS Access the size of Database decrease on deletion of Records if any ?If so how it can be done ?

What I use to do was, to repair the db.
Tools, Database Utilities, Repair
&
Then use compact. Not sure why it happens. Might have something to do with system objects in access?

You have to compress the database. I can not remember how to do it from C++, but it's possible to do through ADO...

Hello,
I'm urgently looking for a nice little commandline tool (with stdoutput) to stamp the version of an executable (Major, Minor, Build).
Has anybody come across something?
Thanks,
Matthias

You can quickly create you own program to extract this type of information.
On nt, you have version.dll, which has windows api function GetFileVersionInfo.
Good luck.

I want to get the cchTextMax property of treeview item.
I'm using the following:
TVITEM tvitem;
tvitem.hItem = m_tree->GetSelectedItem();
tvitem.mask = TVIF_TEXT ;
m_tree->GetItem (&tvitem);
but it doesn't work
at the same time code:
TVITEM tvitem;
tvitem.hItem = m_tree->GetSelectedItem();
tvitem.mask = TVIF_IMAGE ;
m_tree->GetItem (&tvitem);
works correctly
|
|
|
|
|
You can't get just the length of the item's text. When you set TVIF_TEXT, the control expects you to pass in a buffer (along with its size, in cchTextMax). Since you don't have a buffer, the call fails.

Have you tried...
CString strText = m_Tree->GetItemText(m_Tree->GetSelectedItem())

Hi all,
What is best algorithm for get space between two dates ?
For example space between:
01-02-97 to 05-01-98 ???

If you're using MFC, the CTime class overrides the - operator and returns a CTimeSpan class, so you can use it as follows:
CTime vtTime1, vtTime2;
CTimeSpan vtSpan;
vtTime1 = CTime::GetCurrentTime();
Sleep(20000);
vtTime2 = CTime::GetCurrentTime();
vtSpan = vtTime2 - vtTime1;
ASSERT(vtSpan.GetTotalSeconds() == 20);
If you're using OLE DATE classes, try COleDateTime and COleDateTimeSpan which do similar things.
