IBM DB2 SQL Error Code to String

public:
CDCDlg(CWnd* pParent = NULL); // standard constructor

// This is the constructor for your class.

// Dialog Data
//{{AFX_DATA(CDCDlg)
enum { IDD = IDD_DC_DIALOG };
// NOTE: the ClassWizard will add data members here
//}}AFX_DATA

This is where the class wizard adds all the data members that you create using the class wizard (ex CEdit , CButton etc)that is why those //{{ brackets are placed to inform the class wizard where to add the code.

and any overrides ex declaration for PreCreateWindow the declaration is added in the protected section that you do using the class wizard.

Somethings seem HARD to do, until we know how to do them.

a code (i think create with VC6) and a header for DCDlg.cpp (maybe)

this line CDCDlg(CWnd* pParent = NULL); is like this

CDCDlg::CDCDlg(CWnd* pParent /*=NULL*/)
	: CDialog(CssDlg::IDD, pParent)

{
}

enum { IDD = IDD_DC_DIALOG };id from your Dialog

<br />
protected:<br />
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support<br />

void CDCDlg::DoDataExchange(CDataExchange* pDX)
{
	CDialog::DoDataExchange(pDX);
}

In DB2 sometimes error messages are generated and returned in the sqlca.sqlcode variable in C++. To find out the string representation of this number I have to go to http://publib.boulder.ibm.com/infocenter/db2v7luw/index.jsp?topic=/com.ibm.db2v7.doc/db2m0/sql0000.htm[^]. Is there function to return the error string represented by this number so I dont have to go to this web site each time.

I have been researching this for sometime and I found a C++ APIs on this web site http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.ii.doc/ad/rwrutl01.htm[^]. I didnt find any function to do this but it might help.

Another thing. If this "method" could be language specific that would be great too (meaning if English is defined return an english string or if German is defined return the german string).

Thanks Chris

are you sure - report_error looks like it might do the trick - else it points to an include sqlcodes.h that might have the strings in an array you can use

as for i18n .. hmm you might find a german version of the error codes/text somewhere in the install

Thanks for the response. I have researched report_error and found tried using it. I am having trouble finding examples on how to use it and what it does exactly. I am guessing it displays a message to the user? I found 1 example searching on google http://webkemper1.informatik.tu-muenchen.de:8080/interna/db2/en_US/index.htm?openup=ad/t0009587.htm[^]. It is not a very good example because I took that same code and placed it into my project and I get and error stating "Unhandled exception in qadocm.exe (DB2QG.dll): 0xC00..005: Access Violation.

Why do you really want to use the java library in C++?
AFAIK , You will need to host the JVM for that ..

You can run jar file if and only if you are hosted JVM. But you can open, view, read and modify the Jar file from VC++ since Jar file has the same file format as ZIP file.

Here is library which can be used for accessing zip archives.

Trying to Display HWND as String

redfish342-Jul-06 23:37

I am a beginner. I am trying to display the HWND when i use certain Win32 functions such as GetForegroundWindow() for debugging purposes. When i use MessageBox or OutputDebugString such as below...

m_foreHwnd1 = GetForegroundWindow();
MessageBox(NULL, (LPCSTR)m_foreHwnd1, "INFO", MB_OK);

OutputDebugString("ForeHwnd1: ");
OutputDebugString((LPCSTR)m_foreHwnd1);
OutputDebugString("\n");

... I get errors like the following:

First-chance exception at 0x77e26673 in SendFocusWin.exe: 0xC0000005: Access violation reading location 0x00090548.
Unhandled exception at 0x77e26673 in SendFocusWin.exe: 0xC0000005: Access violation reading location 0x00090548.

Can i display the HWND so i can see what the heck is going on in my code? What is the How To?

First thing you need to learn is that you do not cast things without knowing exactly what you are doing as you can shoot yourself in the foot, like what you have done here.

m_foreHwnd1 = GetForegroundWindow();
CString szMessage;
szMessage.Format(_T("ForeHwnd1: 0x%08X\r\n"), m_foreHwnd1);
OutputDebugString(szMessage);

2-Jul-06 23:58

Did you try Format function of CString

else try this

CString strHwnd;
strHwnd.Format(_T("Handle is: %d\n"), m_foreHwnd1);
OutputDebugString(strHwnd);

GetForegroundWindow() API will return handle to active window with which user is interacting, so in debugging mode you constantly switch between your app and debug window. so its difficult to know window handle.

Not sure what are you trying to do, but try this to display window handle in output window.

CString str;<br />
str.Format("%x",m_foreHwnd1);<br />
OutputDebugString(str);

Hope this helps

I think i posted on the wrong forum. I now see that there is a forum that supports STL questions, which i think would help come up with a ANSI version of the solution you folks provided. Sorry. But thanks for the excellent response!

If you really want to split a window and know how it is done a simple way is to Create a new MFC Application and in the fourth or Fifth step(I don't remember exactly) you can choose for Window Explorer view instead of MFC View.
In this way you will be able to see a window split in two parts just like the explorer.
If you want to see the code open the mainframe.cpp file and there you can study
OnCreateClient function

You just have to get with that in the same manner as in my previous post.Just pass the number of partitions you create to CreateStatic and that number of classes that are derived from CView will help.
