You can ask the user how many lines to print and then make sure you only print that number of lines in the code that actually passes your document to the printer.
That the printer is dot matrix is totally irrelevant.

Can someone recommend a book, etc. from which I can learn about interfacing with Internet Explorer from within VB? For example, I'd like to learn how to start IE, go to a WEB site, fill in a search box, command a search and then capture the results all from within a VB program.
Would appreciate any suggestions you can offer.
Thanks,
Dennis

You would do this by placing a web browser control on your form, so you can interact with it, and then use the DOM to find your controls and interact with them. Of course, once the page you're working with changes, your code could well break.

 I am reading images from a webcam, thru a Belkin F5u208 interface to a USB2.0 port. This works fine. What I need to do is poke around in the actual video data to look for certain events in that video data. I set up the display window as follows:-
hwdc = capCreateCaptureWindow("My Window", ws_child Or ws_visible, 0, 0, 320, 240, MyPicture.hWnd, 0)
Is there an API call which will take either hwdc or MyPicture.hWnd as a parameter and deliver me a real memory pointer as a Long? I can then use this as a ByRef in a procedure and access the data as an array. If no API call, has anyone actually done this, and if so, how?

Not in Windows, no. You'd need the an SDK that works with that camera.
But, a pointer wouldn't do you any good in VB.NET, or since VB.NET doesn't support pointers. C# on the other hand...

Hi Dave,
Thanks for the info - we will use C for the final version, but VB is my "natural" home for messing about, and I can do it in VB6, it is not as picky as the later versions of VB.
What exactly does "hwdc" point to? A structure with pointers?

"hwdc" is a handle to a device context. It's not a pointer. The closest equivilent is the Graphics class in .NET.

Hi Dave,
Yes, I understand that. I am re-reading all about GDI handle tables and how they relate to the user and the referenced object(s). My source is "Windows Graphics Programming - Win32 GDI and Direct Draw" by Feng Yuan (HP), Prentice Hall ISBN 0-13-086985-6. Not exactly bedtime reading, but there are a number of very useful tools which I used previously to identify what was going on (creating spy DLL's, APIMON etc), and some interesting analysis of bitmap operations.
The end result is heading for an embedded XP system running on a PC104 card performing realtime image analysis, so I don't mind bending the rules or creating a "one-off" special DLL.
Thanks again,
Chris

I created a stored procedure to return data to a data set. The stored procedure has one input param and contains a temp table for processing a couple columns (adding a join in this scenario will not work). I have a
The stored procedure works find and returns a result set as expected.
I attempt to create the new datatable in the dataset by right clicking in the designer and adding a new tableadapter.
I choose existing stored procedure and get to the last screen of the config wizard and get "Invalid object name #tmpStatusHistoryReasons".
Anyone know of a work around for this? Using framework 2.1.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

This is a known issue even in VS2008. Adding the following condition works (even though the code never gets executed):
IF 1=0
BEGIN
SET FMTONLY OFF
END

There are known issues where the installation stalls, but few known solutions. See this[^] post for more information and a data collection utility to help MS troubleshoot the problem.

Hi,
Can anybody please give me idea to replace functions 1. GetFileName 2. GetFile 3. Copy of FileSystemObject with the functions of Windows API.
As I have done using CreateDirectory() of Windows API for the method CreateFolder() of FileSystem.
Thanks,
Aleem Mohammad.

This is a complete waste of time. The FSO uses those very same functions itself to do it's job. Like I said yesterday, you're not going to gain any performance benefit from doing this.

Hi,
Is there any more efficient way of concatenating the strings than using "&" for performance wise. so that I can use them in my frequently called functions.
If possible with two line code snippet or any link.
Thanks a Lot,
Md Abdul Aleem.
