I have not added any new segments to the .def file .. In fact until the emergence of this problem I was unaware of the existence of the def file and segments .. any explanation would be helpful ..
I simply added some new c files to an existing project .. the project was fine prior to that. The files added have no compilation issues and are used on other projects without any problems ..

 Hi everyone,
Hi everyone
im very new to visual c++ programming, although i worked on borland c++ before.
i have a problem in controlling some controls according to a certain conditions.
for example;
I have two dialogs:
The first one is to ask the user
How many edit boxes he want to see?
The second dialog should show him the number of edit boxes he entered in the first editbox;
So if the user has entered (2) in the editbox in the first dialog,
he must see two editboxes in the second dialog.
It is very important for me to know this
Please just remember that im very new to MFC programming, so write me a clear code as a beginner.
thank you for reading my messege

void CYourDialog::OnButtonEnterDlgNum(void)
{
char lpBuffer[256];
m_YourEditCtrl.GetWindowText(lpBuffer, 255);
// you could also use this
// GetDlgItem(IDC_YOUREDITCTRL)->GetWindowText(lpBuffer, 255);
int iMax = atoi(lpBuffer);
CEdit *ceEdit;
for(int i = 0; i < m_yourint = iMax; i++)
{
ceEdit = new CEdit;
ceEdit.Create(0/* your styles */, CRect(0, 0, 0, 0) /* your rect */, m_YourSecondDlg /* the CWnd object of your 2 dialog */, IDC_ID + i /* your ID (must be unique!)*/);
}
}
hope this helps

Which recordset to use CRecordset or CDaoRecordset with Ms Access database?
I had seens many posts,threads and source code on various forums that uses CDaoRecordset with MSAccess data baseand some uses CRecordset
WHat are pros and cons of using each of them?
WHich one is better? 
Thanking you?
|
|
|
|

The main difference is that CDaoRecordset accesses data through a Data Access Object (DAO) based on OLE. CRecordset accesses the DBMS through Open Database Connectivity (ODBC) and an ODBC driver for that DBMS. The DAO classes generally offer superior capabilities because they are specific to the Microsoft Jet database engine. So you need to decide if you want to access the data through DAO or ODBC, although the DAO classes can access both types of data sources. That will govern which class to use.

Does anyone know how to change paper size while printing under MFC?
The idea is that page sizes are supposed ti differ from page to page (custom sizes)
|
|
|
|
|
Had slight computer problems.
|
|
|
|
|
Do you want to change the paper size during a print job or do you want to have different paper sizes for each print job?
If you want to set the paper size for a print job you have to get the printer DC and then you can change the dmPaperSize member of the DEVMODE structure.
But I think you should give some more information what you exactly want to do.

|

Different paper sizes in one print job, every page different, not standard but custom (arbitrary) paper sizes.

You'll need probably different print DC to each page.
CPrintDialog dlg;
HGLOBAL hDevMode = dlg.m_pd.m_hDevMode;
DEVMODE* dm;
CDC dc;
::GlobalAlloc(hDevMode, sizeof(DEVMODE));
for (i = 1; i <= nNumOfPages; i++)
{
if (dm = (DEVMODE*)::GlobalLock(hDevMode))
{
dm->dmPaperLength = 123;
dm->dmPaperHeight = 456;
::GlobalUnlock(hDevMode);
}
dc.Attach(dlg.GetPrinterDC());
dc.DeleteDC();
}

Doesn't work on all printers, on many it sets the paper size to deafult. I also need to get the orginal paper sizes from devmode, but it doesnt always report them correctly (sometimes both are 0).

Hi i am adding to the ms -access database through the MFC code
CRecordset. Prior to adding the record last designID was 74
<br />
CRSDesign dRS(pdb);<br />
<br />
if(!dRS.Open ())<br />
return FALSE;<br />
if (!dRS.CanAppend ())<br />
return FALSE;<br />
<br />
dRS.AddNew();<br />
dRS.m_DesignName = DesignName;<br />
dRS.m_DesignType = DesignType;<br />
dRS.m_Remarks = Comments;<br />
dRS.m_D_Designer = Designer;<br />
dRS.Update();<br />
<br />
dRS.Requery ();<br />
dRS.MoveLast ();<br />
long DesignID = dRS.m_DesignID ;<br />
AfxMessageBox(_ltoa(DesignID,cc,10)); ---> 74<br />
Message box also gives design id as 74. How to overcome this.?
Well
Select @@IDENTITY as num FROM B_DESIGN
query with MS- Access Database does returns just
0
0
0
0
0 For the number of record i am having in my table
Main Problem
DesignID is autonumber field in my data base and is primary key
It is having following values:
12
15
23
70
71
73
74
112
Now when i am running following query into data base (MS-Access query)
SELECT Last(DesignID) FROM B_Design
it returns 74
Even i put a loop after requery and getting designID in message box it starts from 112,5,12,15 .......
When i move recordset to MoveFirst() it will give designID - 112
and when MoveLast() then it will give 74
Have any body idea about this?
How to resolve this problem?
If any more clarification is required please ask for that?
|
|
|
|
|
How about using
SELECT Max(DesignID) FROM B_Design
instead?

Hi,
For memory stats we have overloaded the operator new in such a way that it allows us to allocate memory and store information about which module is doing it. This is all great.
However, now that we have moved to a multi-threaded environment, do we need to protect the call _malloc_dbg(...) (in a debug build) and the ::operator new(...) (in non-debug) with a critical section?

better idiot-proff programs, and the Universe trying to produce bigger and better idiots.

in dos one could access hardware directly because dos's singe-threaded. multi-threaded oses like windows have to take care themselves that hardware pieces are accessed by just one program at a time.
this means for you that not you're allocating memory, but the os's doing it for you; you don't need any multithreading resource-locking techniques at all.

Multithreaded operating systems do not protect your from accessing hardware at the same time. Two threads can access the same page of memory and cause all sorts of mess if locking isn't used to manage the data in the page.

I'm going to patent thought. I have yet to see any prior art.

When you build with the MT (multithreaded) CRTL (c run time library), you will be getting the multithreaded version of new and delete which have built in locking support. You don't have to worry about it.
