Dear All,
I am not able to Find the Wrong with the Following Code.
Please Help me out.
SQLHENV envHandle;
SQLHDBC ConnHandle;
SQLHSTMT StmtHandle;
SQLRETURN Ret;
SQLSMALLINT szConnStroutlen;
SQLCHAR sZ_AuthorName[50];
SDWORD sdoutputDataLen;
unsigned char szConnStrout[255];
Ret = ::SQLAllocEnv(&envHandle);
Ret = ::SQLAllocConnect(envHandle,&ConnHandle);
Ret = ::SQLDriverConnect(ConnHandle,
NULL,(SQLWCHAR *)_T("Driver={Microsoft Access Driver (*.mdb)}; DBQ=C:\\Uday.mdb"),
SQL_NTS,(SQLWCHAR*)szConnStrout,sizeof(szConnStrout),&szConnStroutlen,SQL_DRIVER_NOPROMPT);
Ret = ::SQLAllocStmt(ConnHandle,&StmtHandle);
//To Fetch a Relative Record.
Ret = SQLFetchScroll(StmtHandle,SQL_FETCH_FIRST,0); //The Code is Failing here.
Thanks & Regards,

According to thedocumentation[^], you should be looking into the return value of the function, and then based on the return value, you should be able to identify the reason for failure (if any). Have you done the diagnostics? Why does it fail?

I'm sorry to know that you're in deep trouble.
The said function returns a value that you should check. If the function fails, the return value actually tells why did it fail so. Take a look at the "diagnostics" section of the documentation page to know more.

I use Win32 Dynamic-Link Library and I would like to create a member that can show something like a MessageBox with OK button (Exit), it also shows a message (ie: "Please enter your comments in the User Input") and a TextBox input.
After the user entering his/her comments then hits OK button, it will return the user input!
Do we have any thing available like that? If not, might anyone help me on this?
Thanks in-advanced

Yes it's called a Dialog Box[^] (CDialog if MFC).

Hi Richard,
I am trying to get any codes related to your link (only information) & others in order to create a Dialog box from my Win32 Dynamic-Link Library project ... but couldn't find any thing yet!
Any suggestion?
Thanks for help

The link he gave you was a good one. The fact you're asking a basic question (nothing wrong with being at the start of something) means you have a lot of learning to do. The link he gave you is Microsoft's explanation of the concepts.
There are many links throughout that article pointing to more specific things.
As for an actual function?
Try: DialogBox, or CreateDialog.
You'll also need a Dialog resource. And if you're in pure Win32, you'll have to learn about instance handles.
(All of this is googlable - I'm trying to give you search terms)
If you're starting from nothing, then this is not easy stuff. Don't expect to solve it in 10 minutes.
Also, you cannot expect someone here to write "codez" for you that will do exactly what you want. What he was trying to do was to steer you at learning material so you can do it yourself - or at least start to, and ask more detailed questions later.
Good luck,
Iain.

you'd probably need to post this in the "Managed c++/cli" forum.
anyway, there's stuff missing from you post.

Hi all,
I have written a program which can monitor a specific program when it was closed.I used hook to do it and everything seem be ok but the problem is that I cannot hook WM_CLOSE message.
I have tried to use WH_GETMESSAGE, WH_CBT, WH_CALLWNDPROC. But all of them seem not work properly!
here is my code:
hHook = SetWindowsHookEx(WH_CALLWNDPROC,fnHookProc,hInstDLL,tid);
DLLEXPORT LRESULT CALLBACK KeyboardProc(int nCode,WPARAM wParam, LPARAM lParam)
{
LPMSG msg = (LPMSG)lParam;
if(msg->message == WM_CLOSE )
{
}
return CallNextHookEx(_hHook,nCode,wParam, lParam);
}
anybody help me.
thanks

There must be something special about the WM_CLOSE message. Are you using a DLL? Are you calling SetWindowLong() in that DLL? Are you injecting the DLL into the process of the "specific window?"

Because this is a global hook which will monitor all message before they really reach to target window. So I think It doesn't need inject the dll to the target window. But I will try.
I took a round from google and know that many people have the same problem with me when they try to catch the WM_CLOSE. But I still cannot find the solution.

You hook handler seems to be incorrect. For instance if you are using the WH_CALLWNDPROC, the handler should be like
LRESULT CALLBACK CallWndProc(int nCode,WPARAM wParam, LPARAM lParam)
{
PCWPSTRUCT msg = (PCWPSTRUCT)lParam;
if(msg->message == WM_CLOSE )
{
}
return CallNextHookEx(_hHook,nCode,wParam, lParam);
}

ok, KeyboardProc must be renamed to fnHookProc. But this is not the cause. This just a mistake when I copy from my code.
LRESULT CALLBACK LRESULT CALLBACK fnHookProc(int nCode,WPARAM wParam, LPARAM lParam)
{
PCWPSTRUCT msg = (PCWPSTRUCT)lParam;
if(msg->message == WM_CLOSE )
{
}
return CallNextHookEx(_hHook,nCode,wParam, lParam);
}
