I have a list control in Icon view. I add somes items with icon into my list, and my list open, I don't see all the text for each items. What I see is the icon, and under the icon, the begin of the text with "...". How can I see the full text without I need to click on the icon ?

Maybe this will help you:

LVS_EX_LABELTIP
Version 5.80. If a partially hidden label in any list-view mode lacks ToolTip text, the list-view control will unfold the label. If this style is not set, the list-view control will unfold partly hidden labels only for the large icon mode.

As far as i know, the list will never display more than two lines of text. However, you can increase the amount of text displayed by allowing more space between icons (this will let each row of text become longer). Use CListCtrl::SetIconSpacing() or LVM_SETICONSPACING to accomplish this.

BTW - rocky's suggestion is also good, as it lets you see the text while hovering the mouse over an icon, while keeping the spacing reasonable.

SNTP server

I've to develop an simple SNTP server (no time performance are required).
Can someone give me some advices to develop it ?

I've created a RAW socket in order to receive any
message sent to my pc, to separate NTP messages
and to know the sender IP address and port. But it doesn't work !!
Is this the right way ?
Can someone help me ? Thanks a lot !!

I tried doing some stuff in windows with RAW sockets a while back and none of it would work (outside of simple PING stuff). I came to find out that windows didn't fully support RAW sockets. I don't know if this is still true with XP, but you may want to check into that.

Don't use RAW sockets, (S)NTP uses normal UDP. Create an UDP socket that listens on port 123.

Will anybody help me

How compiler will determine the parent in virtual derivation

Ranjish11-Feb-05 2:18

Ranjish

11-Feb-05 2:18

I have a base class A. I have derived two classes B & C from A virtually. After that I have derived Class D from B and C. Class have a function fun().
I have created One object of D say obj and when I call obj.fun() it will call fun() of A.
Till now everything is fine.

But what is wondering me is how compiler knows weather fun() is coming to D through B or C as both have one copy of fun() and D also will have only one.

Re: How compiler will determine the parent in virtual derivation

Michael Dunn11-Feb-05 5:13

Michael Dunn

If I understand, your classes are like this?

class A { public: fun() { } };
class B : virtual public A { };
class C : virtual public A { };
class D : public B, public C { };
 
D obj;
obj.fun();

There is no ambiguity there because there is only one method called fun(). When you write obj.fun(), the compiler searches the inheritance tree for something called fun() and finds it in class A. Classes don't have "copies" of functions, the search for non-virtual methods is done at compile time.

Printing large BMP file

Hi,

I have created an application which combines 3 bmp files and sends the raw data to the printer for printing. In a 600 dpi printer the data send from the application is large. I am using BitBlt() function to send the data to the printer. Can anyone help me in this?

How to reduce the printer buffer size? Is there any other format to send data to the printer.

Kindly help.

Thanks.. Smile | :)

Just a note. BitBlt may not be supported by all printer drivers, so you may find that your code works for one and not another printer. You should converts any bitmap to a DIB and use StretchDIBits() to output pictures in theis way. Take a look at my "Printing tips and tricks" artile in the printing section. It gives example code to do the conversion.

To your question: Does it really matter what output size the printer file is before sending it to the printer?

If you vote me down, my score will only get lower

I see that the amount of print data send to my printer is over 163MB. And when I try to print a 'pdf' file, around 400MB data is send. How can we reduce this? Kindly help

VC++7 Char set ????

I have to convert a command to be sent to a piece of hardware from hex to char... i've done this in the following way and it works in vc++6 but not in vc++7 ?? it compiles fine in both but the command is different... anyone got any ideas why ??

CString csTrigger

csTrigger.Format("%c%c%c%c%c%c",0xFC,0x06,0xC3,0x00,0x04,0xD6);<br />

any ideas would be appreciated..

If I understood you correctly, you want to display the given hex digits as a string representation. If this is the case then you need to use the %X format.

<code>csTrigger.Format("%X%X%X%X%X%X",0xFC,0x06,0xC3,0x00,0x04,0xD6);
</code>

Why your sample code would change behaviour on VC6/7 I haven't got a clue! Confused | :confused:
