using dbms_pipe with C++ to perform daabase operation
using dbms_pipe with C++ to perform database operation
I am getting two result: string and int in c++ code. That I want to store into database. The request which generates result is very frequent. So each time performing db operation to store the result is costly for me.
So how this can be achived using dbms_sql? I dont have any experience and how to start with it. I did google but not clue.
So fo I need to set environment,software or library? I am working in linux.
I could not find any such example on web!

Integration with Word
Hi All.
I', new here are fairly new to C++ so please excuse my ignorance! I'm undertaking a project at the moment which requires me to hook into a custom c++ application from a Java applet via JNI. The c++ application needs to communicate with MS Word and potentially other office programmes in order to highlight text and offer find/replace functionality programatically. The idea is that when the applet is launched, it will communicate with the C++ methods to hook into an open MS Word document and highlight all words that start with the letter 't' for example.
I'm concentrating on the C++ side of things first and i'm just wondering whether anyone can point me in the right direction? Even some basic access to an open word document would give me a great start!
Thanks in advance for your help.

Dialog like Window for settings parameters
Hi guys,
I got a main window with menu and the option settings. When I click settings a "dialog" should appear, where the user is able to set some parameters - into a global variable. This window will have something like 12 columns and 8/16/32 (this will vary) rows. This gives us plenty of controls, mostly Edit Controls, which can be filled by the user.
My question is, how to make this window effectively. I was considering dialog box modal/modeless, the problem is the way you have to define a dialog box -> resource file. Defining all the controls in a resource makes the code somehow not very flexible, when I want to change something.
I was trying to make some sort of child window, which is created as follows:
In the WM_CREATE section of the window procedure I call a function, which creates all the buttons, edit boxes etc.
But it's not the child of the main window, which can probably cause trouble in the future (don't know right now). What is good approach to create such "complex" setting windows like in Code::Blocks for example or other pieces of SW? Is it done with dialog boxes through resources? What are the pros and cons of different approaches?
Thank you for advices! :-)

I have create a simple program with database in access.But i have a problem.
I have a field that i put numbers like that 18-03-0000969-000-00. So when the user try to insert a number like that on database i have a problem. My code for that field is this:
ADOTable1->FieldValues["AR_PAROXHSD"]= Edit2->Text ;
and the field on access is "text ", size:255, required:yes,
So when the user insert a new record and a number like 18-03-0000969-000-00 on database insert a number only 14 or 15 and i dont know why. can anyone help;

WM_NCHITTEST and WM_NCCALCSIZE on Awesomium UI
Hello. I'm currently working on a custom interface utilizing the Awesomium library (Chromium rendering engine for use of HTML, CSS and Javascript for UI). I've read through the tutorial on how to "extend" the windows frame into the client area to hide it behind what is drawn in the client area (http://msdn.microsoft.com/en-us/libr...v=vs.85).aspx). I have successfully accomplished this task, but NCA hit-testing that is supposed to be happen by using the DwmDefWindowProc or the custom hit-test method does not occur. When I first launch the WM_NCHITTEST and WM_NCCALCSIZE messages are dispatched, but never again after the awesomium window area covers the frame. Thus it seems like the mouse cannot be captured in these areas (borders and caption).
So the gist of it is: I need to retain the move/resize/snap-to-size functionality of the windows frame while it is hidden.
Here is the code I have so far:
Any help with this would be greatly appreciated!

win32 listbox not populating right
Hi guys,
This is my first posting here, i am trying to learn to program a win32 GUI in code blocks 12.11, but here is the problem,
I have got 2x list boxes on a dialog box window(IDC_LIST1 > Personal Project Notes) and (IDC_LIST2 > Shared Project Notes),see attached pic,

The problem arises when i click the button(update personal) after clicking the(update shared ), it loads the contents of (shared project notes) into the(personal project notes) list box, even after using the clear button too, this still populates (the personal project notes) when clicking the (update personal)button, see attached pic,

Win32 child control thread
I created a dialog with a child control, child control has it's own thread and message pump, and it has the dialog window set as the parent.
Is this a bad idea?
I already noticed I cannot wait on the window creation from the main dialog thread, because when the child thread calls CreateWindowEx with my dialog hwnd as the parent, it must invoke the main dialogs message loop, because I get deadlock.
As long as I don't do that, everything seems to work ok.
Do child windows post or send messages to their parents which could potentially cause me more deadlocks? (If I am going to use sendmessage to contact my child control this could cause problems)

understanding istringstream in c++
Hi,
I am new to c++ and in process fo understading and learning string class.

That is; string has been split up by space.
If I replace space by comma, the output is 32 and all 0 there after.
I cannot understand how it actually works.
PS: Apolologies, if I have posted question in wrong forum. Kindly provide me so not repeat mistake in future.

if(CLogger::oLogger != NULL)
{
LOG4CXX_DEBUG(CLogger::oLogger,"Testing application...");
}
}
In my main I am initializing Log class object and calling Debug method to log debug message to a file.
Issue I am facing is at if(CLogger::oLogger != NULL) which is always returning oLogger as NULL.
Can anyone offer any help on this.
Loh.h
class Log
{
public:
Log(void);

void Debug(const char *msg);
private:

};

LoggerPtr oLogger = NULL;
Log::Log()
{
LoggerPtr oLogger(Logger::getLogger("Test"));
PropertyConfigurator::configure("Logger4CXX.properties");
}
void CLogger::Debug(const char *msg)
