HOW TO IMPORT A TAB DELIMITED TEXT FILE INTO AN ACCESS DATABSE PROGRAMMATICALLY?

Hi ,
I am searching for a good sample code or article that takes a tab delimited file as input and imports it prograamatically in an access database.I don't want to loop through all the records in the text file and then put them individually into access.I want to import the whole file programmatically into an MS ACCESS table.May be it requires OLE.
Any help will be appriciated.
Thanks and regards. Smile | :)

Connecting to the MDB using DAO classes and looping through the records in the CSV file and inserting them isn't that bad an idea.

I think ODBC allows a DSN to be associated with a tab delimited file. It might be workable to assign a System DSN to the tab delimited file and then you could use ODBC to move the CSV file to an Access table.

I'm going to live forever or die trying!

Or, simply define the text file as an ODBC DSN and create an external Link in acess. Then, you can do a standard insert/select query right in access.

onwards and upwards...

Can't compile dll in debug mode

I created a dll with MFC as shared library. In order for me to have different name and type of dll for each mode (debug and release), i used this code in MyDllLib.h. This file will be called by exe from stdafx.h file.

#if defined _AFXDLL
#ifdef _DEBUG
#pragma comment(lib,"MyDlld.lib")
#pragma message("Automatically linking with MyDLLd.dll")
#else
#pragma comment(lib,"MyDll.lib")
#pragma message("Automatically linking with MyDll.dll")
#endif
#endif

but whenever i compile in debug mode, i got this warning..

Linking...
Creating library ./bin/MyDlld.lib and object ./bin/MyDlld.exp
MyDlld.exp : warning LNK4070: /OUT:MyDll.dll directive in .EXP differs from output filename "./bin/MyDlld.dll"; ignoring directive

it doesn't have any problem in the release mode... can anybody tell me why this is happenning..

One more thing, when compile in debug mode, my exe will search for release mode of MyDll.dll and not debug mode (MyDlld.dll)...

Thanks in advance

You probably have a module-definition (.def) file which has a LIBRARY statement in it.

The LIBRARY statement is actually unnecessary, you can simply remove it.

I m developing a whiteboard program.
I need to implement text drawing on a view as in Win Paintbrush.

Could anyone give me some suggestion?Some sample code is better.

Thanks

A good basis for something like this would be the SCRIBBLE sample program that comes with MSDN.

You could have a toolbar which switches between graphic modes. In Text mode, you can detect a
OnLButtonUp event in your view and pop a box asking for text.

There are plenty of text input dialog boxes here on CodeProject you could use. And its not hard
to get ClassWizard to make a dialog box with an edit box in it for you. If you are clever, you
could handle EN_CHANGE notifications from the edit box and live-update the view with the text
you are typing in.

For drawing the resultant text, just use
pDC->DrawText (...) function.

I hope that helped,

Iain.

With your reply ,I get the way to solve my question!
Just 3 type as you said, right?
1. make a resource to tell my view that i will draw text on it

2. catch LBUTTONUP message and pop a edit box

3. Notify the view and DrawText

baybe it ll take me sometime to solve it.Anyway, thanks for your advise!

I would do this in the following order:

Forget about the UI to start with, amd simply practice drawing text into the View at a hard
coded place. This will let you learn about CFont, pDC->SelectObject, pDC->SetTextBkMode,
pDC->TextOut / pDC->DrawText.

Then make a toolbar so you can switch between graphic modes (pen, line, text, etc).
Create Command Handlers for them, so the button / menu for the current tool is inset / ticked.

Then in your mouse button handler, pop up a box to input some text. Add the text and its
coordinates (from the mouse position) to a list of some kind in your CMyDocument. Redraw
the screen with the new text.

Relax in a warm glow of achievement. Have a Beer | [beer]

Class-Constructing function

Class CA

CA();
private:
int a;
int b;
CRect c;
}
CA::CA():c(0,0,100,100){
a=0;
b=0;

What's the difference between both of the initialization ways in function "CA()"?
Thank you in advance!

The initialisation list you used with you variable c is executed before the constructor is even called - it is part of the allocation of the instance.
But on the other hand, you have to be careful: The initialisation list does not care about the order in which you placed them - the are executed in the order the variables are allocated (declared). After all, initialisation lists are part of the allocation.

OTOH, a and b are of undefined value before they get assigned a value. (and they need an assignment operator able to cope whith the values they got assigned - initialisation lists do not.

My opinions may have changed, but not the fact that I am right.

Simple answer, no.

The user can change the console settings themselves, (font, number of columns, rows etc), but the
console takes what is given. If a spiffy UI is what you want, console is not the way to go...

I *believe* you can stream out escape characters to make parts of your text bold, but I'm not too
sure.

Use GetConsoleDisplayMode to see if the window needs to change and if it does send Alt-Enter to the consol window. Thats the only way I know. I havent seen any API that changes the fullscreen mode of a consol window.
