Hello Everyone:
I have an interesting problem. I modified a C# application written by Bob Powell that demonstrated how to move graphic primitives to Visual Basic 2005 .NET.
I want to take this a step further and be able to move alphanumeric characters around on the screen using the mouse. My problem is I can draw a series of characters using the DrawPath method, but when I point to a specific character to hit test it the application’s HitTest Function does not recognize the character. I’m guessing the problem lies in the class I created for the text, but I don’t know how to solve the problem.
I wrote to Bob Powell and he suggested using glyphs. I’m assuming he wanted me to take the fonts and convert them to glyphs. This is where I get confused; a font is just a glyph. It seems redundant to create a glyph out of a glyph.
A single font character has a height and a width. The hit test function returns those values and uses them to create a rectangle around the graphic primitive I’m pointing too. Once the primitive is highlighted I can move it elsewhere on the screen by holding down the left mouse button and move the mouse to another position on the screen dragging the highlighted primitive with it.
Does anyone have any ideas?

I assuming the hit test fails because you can't click exactly on the drawn part of the character and not the white space inside it. You're, basically, trying to click on a very thin line and missing. I hope anyway...
I have no idea if this solution would work for you, but you already know how to click and move a graphic image, so draw the text onto a small bitmap and left the user click and drag the bitmap around.

Hi Dave:
Thanks for the input. The experiment I'm running uses a 50 point font, which in turn produces an image large enough to know you are clicking on the character itself.
The bitmap approch did occur to me as a possible solution, but considering the work involved producing 255 bitmaps, one for each ANSI character it didn't seem like it would be practical.
Obviously there is a fundimental difference between shapes drawn using GDI+ and how GDI+ handles fonts. There has got to be some method out there that will allow me to capture the font, but so far my searches have produced ziltch.

When buying Microsoft programming software, I would always go with the full Visual Studio. Despite VB.NET being only for VB, the full Visual Studio allows you to switch between any programming languages with greater ease. Also, if you are taking computer programming courses, their is a great chance that you will have to use C++ as well which is included in the full Visual Studio.
You may also consider the 2008 edition unless your course absolutely requires 2005.

The first step of becoming a programmer would be, the ability to do a little research. If you were to google, you'd quickly find that 2005 and 2008 can happily co-exist. I believe tat te express editions will also work fine, I've run them on my dev box. But, why would you need them ?
SQL Server is a totally different program, and is completely unrelated.

2003, 2005 and 2008 can coexist on the same machine (I have VS2003Pro, VS2005Standard, VS2008Pro). The only real reason why you would need the express editions is if you were using XNA (unless it has since been changed). Before you could only use XNA on the Express Editions and not the standard or professional versions of Visual Studio.

Hi,
I have a login page which takes the username and password and connects to the Oracle database. The login details are same as oracle db login details. If the user attempts 5 invalid logins to the application, the user id gets locked in both the application and the database. However, if the user is typing the same wrong invalid password consecutively for 5 times, the user id is not getting locked in the database. This means for the same set of userid and password, the post back is not working. Can you please explain and give a solution? We are using ASP.NET 1.0 with VB.NET. Thanks in advance!

hi aaraaayen
You should be Posting this in a ASP Forum. OK lets look at your Problem

Ok, try to Debug your Application, place a Break point from the moment you submit the user input and try to Enter incorrect credentials 5 times as you said and see where it goes wrong because we cannot tell whats wrong until we see your code. but as i said, try to debug and see where it fails and ask a Question based on the failing line and then it will be simple to help you
thanks
