Hi Gurus,

I'd like to know how I can do large images (32x32) in a toolbar?
Where can I get some sample code to do this?

Thanks. Smile | :)

Best regards.

Create a toolbar and change the image size in the resource editor. You need to change it for the main toolbar resource not one of the buttons.

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

Create relative path from 2 absolutes

Hi!

I need to make a relative path, using 2 absolutes paths.

Assume
path1: C:\MyProjects\Tool\Tool.exe
path2: C:\MyProjects\Docs\MyDoc.txt

The output should be ..\Docs\MyDoc.txt

How do I create the relative path??

Thanks and best regards,
Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??
(doesn't work on NT)

You can use the _fullpath function in C/C++.

communicating with windows service

I have to write a windows service in VC++ 6 and need to make a web-based front end for viewing the current state and configuring the running service. What would be the best way to build a web-based front for a service? I am thinking of using sockets at the server and then a C# based front end because it is easy to do socket communication with it. Any suggestions?

Comparing data-types by value

Hi,

As an experiment I was trying the following code:

<br />
CString MyNumber = "23.5";<br />
double mynum = atof(MyNumber);<br />
if(mynum >= 3.4E-38 && mynum <= 3.4E+38)<br />
   printf("Data Type = Float");<br />
else<br />
   printf("Data Type = Double");<br />
<br />
MyNumber = "123456789.12345";<br />
mynum = atof(MyNumber);<br />
if(mynum >= 3.4E-38 && mynum <= 3.4E+38)<br />
   printf("Data Type = Float");<br />
else<br />
   printf("Data Type = Double");

However, this always displays the text "Data Type = Float", so I thought that perhaps the atof() function was loosing accuracy. Does anybody know why the floating-point range test doesn't work?

Best Regards,
Lea Hayes

123456789.12345 is less then 3.4E+38.

Try this:
MyNumber = "1234567890123456789012345678901234567890.12345";
mynum = atof(MyNumber);
if(mynum >= 3.4E-38 && mynum <= 3.4E+38)
printf("Data Type = Float");
else
printf("Data Type = Double");

Decode a UTF-8 file to a CString?

I’d like to Decode a UTF-8 string to a regular CString. I’m using MFC and don’t really know where to start.
I'm reading a UTF-8 coded file using CStdioFile and CFile.

Has the _T(“…”) something to do with it?

At a guess. I'd say that the crashed MsDev process is still running. Have a look at the process list via taskmanager and kill the msdev.exe process

Its a pain when u lose this info . i'd suggest that u look in the task manager and kill msdev.exe if its running . if this doesnt work go to ur project folder and delete
the .clw,.aps,.ncb files and reopen ur project . Hopefully things shld be back .
