Ctrl-Shift-Esc brings up the Task Manager. Click on processes, and sort by use. When you see your app, click on it, sort by name and scroll until you can see it. Then you can monitor usage for as long as you like.

Hi everyone,
I have a CDaoDatabase connection, I open a CDaoRecordset with this.
The problem is: I have more of 30000 records stored in tables. How to get portion of this data.?
for example:
query1 : first 1000 records
query2 : next 1000 records (1001 to 2000)
query# :...
I'm using the RDBMS MSDE2000.
The statement "select TOP ..." only retrieve the first records.
Thanks in advance.

here's one way:
1. create a temp table with all the fields in your recordset and an identity int column.
2. put all the results from your query into that table (INSERT INTO...)
3. SELECT from that temp table WHERE ID BETWEEN 1001 AND 2000
or, if your original recordset has an identity column, you can just use that.

Thanks for you post.
This option downs the performance of the database server. I have a Pentium III 550Mhz on Win98 and MSDE2000 as data server. You Known another method to do this.

sorry, i don't.
i don't know of any Microsoft SQL iimplementations that allow it, but
with MySQL you can use "SELECT * FROM whatever LIMIT low,high".
with SQLServer and Access, i've always had to use the temp table+identitiy field trick

i had made the win32 static library in vc6 and code is given both decleration and implemention are
class CKeyLogger : public CObject
{
public:
CKeyLogger();
virtual ~CKeyLogger();
void KeyLoggerMain();
CKeyLogger::CKeyLogger()
{
}
CKeyLogger::~CKeyLogger()
{
}
void CKeyLogger::KeyLoggerMain()
{
MessageBox("library is called");
}
i made the new MFC application class that includes this as below.
#include "..\\KeyLoggerLibrary\\KeyLogger.h"
and in one of its function in this calss i used the code below.
CKeyLogger obj1;
obj.KeyLoggerMain();
it gives no compiler errors but gives the linking error described below.
error LNK2001: unresolved external symbol "public: virtual __thiscall CKeyLogger::~CKeyLogger(void)" (??1CKeyLogger@@UAE@XZ)
file2.obj : error LNK2001: unresolved external symbol "public: __thiscall CKeyLogger::CKeyLogger(void)" (??0CKeyLogger@@QAE@XZ)

can anybody tell me what to do,

You obviously didn't link your static library. I don't remember how to do it exactly in VC6, but look in the linker options for "additional libraries" or something like that.

I am not sure what you called your static library, let us suppose it is called 'KeyLogger.Lib'
Open the workspace for your new program.
Go to he Project menu and select Settings.
Click on the Link tab and choose Input from the Category drop down list box.
You need to do separately this for the debug and release builds.
In 'Additional library path' enter the relative path to the folder where the KeyLogger.Lib file is located. You might have different folders for the debug and release versions of the KeyLogger static library.
In the 'Object/Library Moduloes" enter KeyLogger.Lib
Click OK for the project settings dialog.
Now your project should link.

i called it the static library bcos i had made by choosing the win32 static libraries in vc6.
i was not able to understand ur comment which is below
You might have different folders for the debug and release versions of the KeyLogger static library.
so tell me form which folder's relative path i should give. debug or relese of keylogger library. what is meant by relative path full path like C:\library\keylogger.lib" or "..\\library\\keyloger.lib".

You can enter a fully qualified path.
If you enter a relative path, it is from where your current project's .DSP file is located.
Also when you enter the relative path, do not use the double backslashes.
So you might have something like this in the 'additional library/path' field
..\Library\Debug
for the debug, and for the relase you would have
..\Library\Release
Then in the 'object/library module' settings, you only enter the name of the library by itself: KeyLogger.Lib

I have just asked a question the day before yesterday, And thanks to Alok and Jörgen Sigvardsson who gave me nice ways to solve my last question.
Now I have got a new question to ask. Can I set the keyboard focus on a radio button when the dialog pop up?
I use GetDlgItem(IDC_RADIO1)->SetFocus(); in the OnInitDialog(). But it didn't work.
//IDC_RADIO1 is the ID of the radio button in the dialog
//where I wish the keyboard focus to stay at when the dialog pop up
Thanks!
|

If you set the focus in OnInitDialog(), you must return FALSE from OnInitDialog(). If you don't, the normal Windows dialog handling will set the focus to the first control in the tab order.
Software Zen: delete this;

|
|
|
|
Thanks!
I tried the method you told me, And it did work in the dialog.
But when I tried this in a fromview, which contains the item I want to set the keyboard focus at, it didn't work.
Because the OnInitialUpdate() function in the CFormView class doesn't have a return value.
What can I do in this case?
Thanks!
|
|
|
|
|
You could try to post your form view a special message, that once recieved, will set the focus for you, after the formview has initialized. Once you are out of an 'init' handler, like OnInitDialog it is easy to set the focus to any control you want. The default handlers almost always try to set one for you, which as you have discovered is not always convenient.

Has anyone been able to determine the state of the checkbox on the standard CDateTimeCtrl?
It is driving me bonkers and I cannot find any documentation realting to it.
Thanks

If you wish, check BCGDateTime control, which is free on there site, you can download code and example, which may give you some idea.

Hi,
I want to use STL containers(list,string.....) in my MFC application.
The problem is that I keep getting errors.
for example, when I declare :
using namespace std;
I get this error:

DLLTestDlg.cpp

Error executing cl.exe.
DLLTest.exe - 1 error(s), 0 warning(s)
and when i declare :
#include <string>
string s;
I get these strange errors:
