Sorry, but it is almost impossible since you didn't use Code tags.
Please, read Announcement: Before you post....

I guess the problem is with the date (DOB column), because the conversion, or lack of conversion, is a common problem with that kind of fields.
Could you try without the date?

Otherwise, enclose your lines of code between [code] and [/code] in your message. This will give a nice frame an indentations like

[ shooting in the dark ] Make a UNICODE build, i.e. add UNICODE and _UNICODE to project preprocessor definitions.
Although, I don't know that can solve your problem, just have a try.

Hi Ovidiu!
I don"t think UNICODE build can help here. I use ADO in ANSI builds since years (if not a decade) without any problem.
And, BTW, thank you for inserting Code tags into post of keerth516. :)

Dear keerth516,
the first thing you should do is forget that goto exists!
There are (or were) some languages where there was impossible to program without goto, but neither C nor C++ belog to those languages. Besides you "cleanup" code does not make any sense because the best place for CoUninitialize is in the main() function *the same module that is used for CoInitialize)

Second, did you debug you code? did you see what exactly your string strSQL contains while being passed in Execute method?

Hi Victor,
Indeed, should be not any problem ANSI vs. UNICODE build, as long as _bstr_t has botn char* and wchar_t* operators as well as constructors taking char* or wchar_t*, as well as...

I was just "shooting in the dark", like said before. ;)

Hi every one...thanks a lot for ur replies...

It was an date format issues..thats why was getting such error....now it insert the values into database.

I have one more doubt reagrding insertion of values displayed in the console window.

I have one application which is in C lanaguage.Am using microsoft visual studio VC++ to debug this application.It will gives the finaly ouput display in console window.I want to insert this displayed values into sqlserver2005.

eg:Below line of code is the values displaying in console window.I want to insert the value of amout and area variable into sqlserver database.

Could u please suggest me any idea to implement this.If u provide any example it would be helpful.

printf("comp: %s ammount %f area %u\n",(analysis->peak + i)->comp,(analysis->peak + i)->amount , (analysis->peak + i)->area);
