It is not necessary that buffer overrun causes it. Possibly you are doing some other thing wrong. If possible, code snippet would help to solve the problem.

If you see the callstack, it might point you in the code, where the problem is.

Its better to post code again. Its not me , who only is seeing this post. And everbody would not want to track your last post. And it would be helpful if you tell where debugger taking you in the callstack.

this is my code......

typedef int (CALLBACK* Set_Quote_DB)(unsigned short**,short*,unsigned short**,unsigned short**,unsigned short**,short*);

// TODO: Add your control notification handler code here
HINSTANCE hInstance=LoadLibrary("WartzODLCOM.dll");
Set_Quote_DB SetQuote;
SetQuote = (Set_Quote_DB)GetProcAddress(hInstance,"setQuoteToDb");

SessID=SessionId;

CString marketstate,marketno,bid\_d,ask\_d;

marketno.Format("%d",MarketNo);
bid\_d.Format("%c",BidDirection);
ask\_d.Format("%c",AskDirection);
marketstate.Format("%d",MarketState);


m\_MainEdit=m\_MainEdit + " + SessionId + "\\t" + RequestId +"\\t"+ a ;

    // debugging error when calling this function...of dll....access violation

Have you checked hInstance, SetQuote for NULL. I'm sure its NULL in your case.

sorry to bother you but can you tell me how to check...i am very new to vc++

[prasad_som]

INSTANCE hInstance=LoadLibrary("WartzODLCOM.dll");
if (hInstance == NULL)
{
// dont go further
return;
}
Set_Quote_DB SetQuote;
SetQuote = (Set_Quote_DB)GetProcAddress(hInstance,"setQuoteToDb");
if (SetQuote == NULL)
{
// dont go further
return;
}

I advise you to learn basic c/c++, before adventuring further.

Thanks for your advice.....i really dont know vc++/c++ but i got this project to be done...and i have no option...but ya after finishing this project this is last stage inserting the data i will first learn this lang. from basic. And now about the problem..now it is ok no error but now it has stoped displaing anything in edit box...and also not inserting the data...any clue

It is because, either your dll is not loaded, or not getting address of function you required. Check from where it is returning, check valid dll is present it the path you mentioned.

yes i have checked my for dll : project->setting->link->C:\ActiveXdll\WartzODLCOM.lib And in c: drive also it is present wartzODLCOM.dll and .lib is present And i have "#define WartzODLCOM" in my cpp file include where i am calling this dll function... Now whats wrong here....:doh: (Or should i need to include header file of dll in my project and then call function.....) -- modified at 4:48 Friday 15th December, 2006

I this case you can directly call dll function. I would suggest reading this series of article[^] to understand usage of dlls.

make sure that you have updated Windows Plateform SDK if not you can download and install it from "http://www.microsoft.com/downloads/details.aspx?FamilyId=A55B6B43-E24F-4EA3-A93E-40C0EC4F68E5&displaylang=en" because the library which contains the "strsafe.h" functions won't be availaible to you without installing SDK. Once u have installed SDK go to Start->Programs->Microsoft Plateform SDK for Windows Server 2003 SPI->Visual Studio Registration->Registerd PSDK Directories with Visual Studio. Once you have done with it you have to include the "strsafe.lib" in your program from Projects->Settings->Link. Now include the "strsafe.h" in your program and and enjoy using strsafe functions. VV IMPORTANT : Include "strsafe.h" at the end of all other include directives. Thanks and Regards, Love Zeeshan Malik
