Thanks

Hi,

Normally bitmaps are stored in 1D arrays.
For exemple you have 640x480 bitmap, the way to get to a pixel would be like this:

<br />
char bitmap[640 * 480];<br />
<br />
// pixel xy]<br />
bitmap[x+(480*y)] = value;<br />

If you want to convert the exemple above to a 2D array, you can do the following:

<br />
char bitmap[640*480];<br />
char bitmap2D[640][480];<br />
<br />
// convert<br />
for( int y = 0; x < 480; y++ )<br />
  for( int x = 0; x < 640; x++ )<br />
    bitmap2D[y][x] = bitmap[x + 480 * y];<br />

Hope this helps..

Bit Fields - Again

I thought I had this problem solved, but I seem to have hit a problem with a 4 bit field on a byte boundary.

Can anyone suggest a solution to an extra byte being added to the structute. I need everything packed tight.

#pragma pack(1)<br />
<br />
typedef struct{<br />
	char	tc1_w01_month_1_s_	:  4;<br />
	char	tc1_w01_month_10_s_	:  4;<br />
	char	tc1_w01_day_1_s_	:  4;<br />
	char	tc1_w01_day_10_s_	:  4;	// This OK<br />
	char	tc1_w02_reserved1	:  1;<br />
	char	tc1_w02_reserved2	:  1;<br />
	char	tc1_w02_minute_1_s_	:  4;<br />

Use int rather than char for the first 32 bits (all except the last 4 fields), and short rather than char for the rest.

It's a good idea to use the largest possible data type size when using bitfields (ie. favour ints/longs). If you need to prevent padding at the end, then by all means use the smaller data types (ie. short/char).

Also, be careful about using signed values in bitfields. Generally, it's a good idea to use unsigned values (eg. unsigned int) because then you can guarantee how the compiler will treat it. If the values are signed, then you have to know whether the compiler sign-extends or zero-extends the value when you're using it in an expression.

Hope this helps,

Ryan

ODBC Driver for Access - database password

8-Sep-04 1:23

Hi,

i am using ADO Connection Strings from this page to connect to an access database. unfortunalty they just contain parameters for userID and user password
e.g.:
strConnection = _T("Driver={Microsoft Access Driver (*.mdb)};"
"Dbq=C:\\VC Projects\\ADO\\Samples\\AdoTest\\dbTestSecurity.mdb;"
"SystemDB=C:\\Program Files\\Microsoft Office\\Office\\SYSTEM.mdw;"
"Uid=Carlos Antollini;Pwd=carlos");

the problem is that the database which i want to connect to is protected with a database password .
is there an other attitional connection string which has the database password as parameter?

thx Bernhard

By default, user id of an access database is "Admin", hence to open a password protected database, use:

"UID=Admin; PWD=your-password"

hmmm if i try like this:

CString strConnection = _T("Driver={Microsoft Access Driver (*.mdb)} Dbq=c:\\exchange-b\\ApplicationDatabase.mdb; Uid=Admin; Pwd=myPass;");
m_DB.SetConnectionString(strConnection);

the programm still cant open (m_DB.Open()) the database. are you sure there is no difference between database base password and user password?
if i set a database password and a user password and then i try to open the database from the win explorer, ms access asks me for both passwords ...
so i think i need a connection string which contains the databasepassword

You'll have to include the database password like so: "Jet OLEDB:Database Password=MyDbPassword;"

copy selected text to my application

Hi,

I'd like to copy the selected text of any other application
with a system-wide-keyboard-shortcut automaticly to my application.

Should be working like in Babylon Translator.

Maybe someone can guide me to good starting point, or better has
some code that might help me.

Thank you
Mario

Look at the WinAPI functions like SetClipboardData and OpenClipboard.

The 'selected text' have to be in the clipboard, the concept 'selected text' is a feature in certain components, and not something inherent in a window or an application.

well thats clear Roll eyes | :rolleyes:

, I like to copy the text, open my application and paste
this text automaticly. And also the other way round:
- press a hotkey
- my application copy's the text into clipboard
- go-back to the window where we came from
- paste the text

The problem is not to copy/paste to the clipboard. The problem is how to
hook the hotkey with my application, then go back to where the user came
from and copy the text into the clipboard. After that my program needs the
focus again and has to paste the clipboard content into my application.

There is no way to do that explicitly, read: nicely. A SWAG would be to somehow trigger a CTRL-C in the window.
Hmmm...
Using Win32 API you can get the active window, then you could send a keypressed message containing CTRL-C, and, hopefully, it would have triggered the app to copy something to the clipboard.

Kind of ListCtrl with two columns

Hello,

I would like to add to my MFC dialog some kind of a ListCtrl, but with two columns. The background is that I have some attributes with names and values and I would like to display these dynamically in this list with the uneditable name of each attribute in the first column and the editable value in the second column.

Any ideas for that?

Thanks
Jens
