So, if it doesn't display question marks, it could be as simple as that the machine is not having the language pack installed. Have you tried Michael Schubert's suggestion? I didn't suggest it right away to ensure that you weren't seeing question marks instead.

Well, I'm not sure. I've never worked with Arabic characters, but have you checked if it's got anything to do with setting the "reading direct order"? (Arabic is right to left).

I think you have to install the language and font support in Windows:
Control Panel -> Regional and Language Options -> Languages -> Install files for complex script and right-to-left languages

Hi all,

I already managed to connect to the dataase-MySQL:-select and insert the data in the database.

But, my problem is, how am i going to put the data into the list.

Let say when I'm doing the selecting, i got 20 records. And each record is contain 4 fields.

How am I going to set the data to

(field1, field2, field3, field4)

Thanks.

res = stmt ->executeQuery("SELECT a, b, c, d from log");

while (res->next()){
res->getString(1);
res->getString(2);
res->getString(3);
res->getString(4);
}

Hi,

Tq for your reply.

ACtually, I have one table : log. And it consist 4 fields.. Currently I'm having 20 records..
What I want to do is to have a struct / linked list..

So when I display the data, it will display like
-(field1, field2, field3, field4)

Why bother with a struct/list when you can display the data straight from the record set?

device context vs GDI

wat is the difference between device context and graphics device interface?

Re: device context vs GDI

See Wikipedia entry[^]

Taken from Above Link:

The Graphics Device Interface (GDI) is a Microsoft Windows application programming interface and core operating system component responsible for representing graphical objects and transmitting them to output devices such as monitors and printers.

GDI is responsible for tasks such as drawing lines and curves, rendering fonts and handling palettes. It is not directly responsible for drawing windows, menus, etc.; that task is reserved for the user subsystem, which resides in user32.dll and is built atop GDI.

A Device Context (DC) is used to define the attributes of text and images that are output to the screen or printer. The actual context is maintained by GDI. An HDC, which is a handle to the structure, is obtained before output is written and released after the elements have been written.

The device context is a GDI-managed structure containing information about the device. GDI contains a number of structures which you cna use to use generate graphical output for display, printers or other devices.

I don't know who in the living frock is marking your questions as "Good" (apparently none of your questions are that awesome to be marked as a good questions). I've noticed this a few times and I wonder if you have a split personality (another login) to "help yourself"?

Remember - the ones likely to provide you an useful answer do not care about if or not the query is marked as good.

Do you need to call CreateInstance() on the rs object before using it?
