This is really not a C++ question, rather one of how to use NetBeans. You should look at the project settings section of your project, where there should be some way of adding the reference to the library you are trying to use. Failing that you could try the NetBeans forum (if such a thing exists).
One of these days I'm going to think of a really clever signature.

C++ has to parts.
- Compiling
- Linking
Header files are using in compiling.
Libraries are used in linking.
If you are getting a compile error then there is something wrong with your includes.
If you are getting a link error then there is something wrong with your libraries OR something wrong with the way in which you used the includes. The latter is often caused by incorrectly using C code (from the library) in C++ code.
For the most part it should never matter what order libraries are in.

@jschell
Thanks for your response, And i just want to know one more thing. So, to add a library to build path, we must have the header files (.h) and also library files(.dll on windows)of that library. isn't it ?

You must specify both somewhere. And it will be in different locations.

hi,
i am using multiple Check Boxes in my GUI and i wanted that only one gets checked at a time i.e when one Check Box gets checked by user the others should automatically get unchecked.
i can't use Radio Buttons since i don't find its "Auto" check and uncheck from "Behavior" in its "Properties" in vs2008.
any help in this regards please.

OnBnClickedCheckXXX() -> uncheck all checkboxes programtically and check "CheckBoxXXX" .
Or write new function and pass control handle of check box to be checked, then inside that function uncheck all , then check passed check box.

thank you sanjaylk. it really helped.

I am using VS2008 and see Auto behavior for checkboxes. See here.

Hello All!
I have been tasked with writing a dialog based application that must include a menu, tool bar and status bar. Being CFormView based is not an option. I have everything working beautifully except 2 items:
1. Tool tips do not display correctly on the status bar panes.
2. I need to resize the dialog once the tool bar or status bar are turned off.
I only need help with #1 as I have not even worked on #2 yet.
I have a normal CStatusBar derived from a class described here:
http://msdn.microsoft.com/en-us/library/ccstww6w(v=vs.71).aspx[^]
The dialog has a base class as described here:
http://msdn.microsoft.com/en-us/library/ccstww6w(v=vs.80).aspx[^]
What happens when hovering over any of the status bar panes is you get a tool tip centered horizontally over the status bar that simply says "Toggle Status Bar". I am seeing the TTN_NEEDTEXT message fire with control ID 59393 which is AFX_IDW_STATUS_BAR.
All of the update commands, tool tips and message strings work for the menus and tool bars as well as the update handlers for the status bar, it is just the tool tips for the status bar that do not work.
Any help is greatly appreciated.

Have a look at the article StatusBarACT[^] and the source code to add the tool tip related code to your CStatusBar derived class.

If a winwird application is started by a c++ programm (borland5) it ist possible to stop the prodedure by
OleProdure("Close");
But otherwise the process still appears in the Task-Manager.
How to end this process by c++?

Somehow you should find the process. I think the easiest way to find it by window. You can use FindWindow() to find the window of the process by either window text (title) or by window class. I recommend the window class because the title is usually variable, you can find out the window class of a window by using spy++. So lets say you know the window classname and you can find the window handle of the window of the process. Then you can use GetWindowThreadProcessId() to get the id of the process and the thread that created the window. You need the process id. Use OpenProcess() with the processid to create a handle to the specified process. You can use the process handle with TerminateProcess(). There are two other more polite ways to do the stuff: When you get the HWND of the program with FindWindow() you can send messages to the window of the process. By using PostMessage to post a WM_CLOSE to this HWND you get basically the same effect as by clicking on the X-close button of the window. The problem with this is that many programs react to this by popping up a "Do you really want to exit?" messagebox and the user can still cancel the program exit. Another solution that is between the WM_CLOSE and the TerminateProcess() solutions is calling DestroyWindow() on the HWND of the program (that destroys the window and before this sends WM_DESTROY message to it). The problem with this is that many programs don't handle this well, for example some buggy programs use PostQuitMessage() from their WM_CLOSE instead of their WM_DESTROY handler and they don't put proper cleanup code to their WM_DESTROY. The less reliable is DestroyWindow() that might be used if we spoke of one fixed version of a program that proved to work with this, but if WM_CLOSE is enough than I would go with that, otherwise with TerminateProcess().

Did you start the instance of Word using something like CreateProcess() or ShellExecute()?

Hello,
I am Using CDHTMLDialog to display an HTML Page along with some MFC Controls.
Using Reference from: http://www.codeproject.com/Articles/1094/The-MFC-CDHtmlDialog-class
&&
http://www.codeproject.com/Articles/5729/CDHtmlDialog-with-CSS-JavaScript-and-images
My query is how do I control the position of the HTML page on the dialog?
I have used OnSize function to control the lower part of the Dialog.
void CTestUIDlg::OnSize(UINT nType, int cx, int cy)
{
CDHtmlDialog::OnSize(nType, cx, 165);
CDialog::OnSize(nType, cx, cy);
}
This code helps in displaying HTML page with height of 165 and the lower part is only CDialog.
I want to achieve the following:
CDialog Size(0, 0, 500, 500) // Full Dialog
CDHTMLDialog(0, 100, 500, 165)// Middle Strip of 65 pixel
The top area of the Dialog should also contain only CDialog Controls!
I don't want to use the WebBrowser Control for this.
Any tip on how to achieve this!
Thank you!

Hi,
I am working on a simple win32 console based application in C in visual studio2005.
My application uses a third party static library.
So I have included the path of the library and the library in additional dependencies for linker input.
My code compiles and works fine if I compile this code as C++ code.
But If I want to compile this as C code, for the same library functions, I am getting unresolved external symbols.
Can any one please let me know, if I have to change anything for this library to compile as C code.?
Regards,
Sunil Kumar

Its possible to do that but depending on your unresolved external symbols you might have to use a thin layer of C++ between your C code and the C++ library.
|
|
|
|
|
The library is compiled as C++ code, due which the function names exported by the library are mangled.
When you compile your code as C code, the name mangling is disabled, due to which the linker looks for un-mangled version of the function calls you're using from the third party library. And hence the unresolved external symbol errors are shown.
The way out for this is use dynamic loading of that DLL.

Hi Malli,
thanks for the reply.
So in that case,by using dynamic loading of library using LoadLibrary, we can avoid this even the library is compiled as C++.?
Regards,
Sunil Kumar

|

Yes, provided that you have function prototype with you and the function pointer defined for the function you are calling.

DLL?

I meant to say using LoadLibrary().

but the post says nothing about a DLL. it says "static library".
