how do I get the path to what on my system is C:\Program Files?

I'm looking up the value of %PROGRAMFILES% currently but this might not be defined on every system.

<br />
TCHAR szPath[MAX_PATH + 1];<br />
ExpandEnvironmentStrings("%PROGRAMFILES%",szPath,MAX_PATH);<br />

any alternatives? Do I have to lookup some reg key?

Thanks.

Use SHGetFolderPath() to get the location of the folder CSIDL_PROGRAM_FILES (that function is in shfolder.dll which you can redistribute, and it comes with any recent OS and IE version)

I use the c function _getcwd to retrieve the current working directory which is almost always the directory the program is running in unless you have your working directory set differently when doing debugs in VC++.

Displaying international strings

How can I display international strings? Is there a function like setlocale which I have to invoke for the various subsystems (GDI, USER etc, etc)

The simpilest way is to use UNICODE. There are articles at codeproject and else where on this subject. Also, if you want to develop international application you should get a copy of "Developing Internation Software for Windows...." [Microsoft Press] (a new revision of this book came out last year).

Hi everybody

I'm developing a small application in MFC, where I need one combobox filled with two different kind of strings.
In between these two types I need a double line, like the one in MS Word Font combo box.

I've made my combo box with owner draw fixed and draw one line at the place where I required. But the line doesnt look exactly the same as in MS Word. Also my combo box is a little bigger when compared with normal combo box.

Please help me out to find a better method to develop this combo box.

Thanks in adavance

hi everybody,

I followed completely the example

http://www.mathworks.com/support/solutions/data/27671.shtml

and tried to learn the idea but I met some linking problem about it.

Linking...

foowrap.obj : error LNK2001: unresolved external symbol _mxCreateDoubleScalar

Debug/test.exe : fatal error LNK1120: 1 unresolved externals

Error executing link.exe.

test.exe - 2 error(s), 0 warning(s)

what can i do in order to settle the linking errors.

and here is another question,

if i plan to call the matlab function
[features, targets] = improved_DA1(x,[cluster,0.95]);
how can i settle such kind of scenario and calling the [ ] in reference with the website tutorial method,http://www.mathworks.com/support/solutions/data/27671.shtml

thank you for your all helping

Can you give me an example of making a Round or Elliptical window ?

Hi!

I would like to be notified when a user presses CTRL+A in an Edit control.

I derived the OnKeyDown function, but I received the notification when the user presses CTRL then when he presses A.

How to be sure that the CTRL key has been pressed when I receive the notification when the A key is down?

Thks in advance!

Use GetKeyState within your handler for the A key being pressed.

Sound Application

Hi,

I would like to design a Visual application that can display external input information from the sound card.

I only really have experience of C and was wondering if there are any tutorials to help design a sound application?

Could someone also recommend a good, free C++ compiler / programming software.

I am sending a file through a WLAN card and from one pc to another. How can I save a file that have been received in the receiver PC? I don't know actually how to use VC++ to save a file in a computer either...

Hello,

I assume that the client pc has to do the saving by itself. When you are using MFC try CFile.

If you(host) have to save the file on the client pc, try some ftp.

Bad font used for buttons using the theme API for XP

Jörgen Sigvardsson20-Dec-03 1:51

20-Dec-03 1:51

This is really disturbing as I only have this problem with some themes (including the standard themes).

When I draw text using DrawThemeText and theme data for "Button, then the font is mismatched sometimes. Using the theme "Watercolor", the font is just like it should be. But with standard XP themes for instance, the font is System. You know.. the butt ugly font. Hmmm | :|

What am I missing here!?

I am using the WTL theme classes, and I did try using the raw API. In both cases I get the same result. If I do this:

hTheme = OpenThemeData(m_hWnd, L"Button");
DrawThemeText(hTheme, hdc, BP_PUSHBUTTON, BPS_NORMAL, CT2CW(szText), -1,
DT_VCENTER | DT_CENTER | DT_SINGLELINE | DT_WORD_ELLIPSIS, 0, &rcClient);

I end up with an ugly text drawn with the System font.

Help. Please?

Nevermind. It seems that this is by design. A really f'd up design if you ask me.

I guess I'll use ordinary HDCs for outputing the text.

That pretty much describes the entire set of theme APIs. Wink | ;)

The GetJob API call will give you number of pages and copies - although for truely rteliable page counts you will need to dissect the spool file.
