The second says that an object reference is required for the non-static method. On this site (in the private methods section): http://www.dotnet247.com/247reference/System/Windows/Forms/AccessibleObject/__members I can use any of the methods or access them as properties of accObj as long as they don't have anything in the ()'s as they appear on the site (the object reference???) like accObj.getChildCount works fine and returns a numerical value. Maybe this is a lead to fixing my problem? Please help!

I am coding in c# and I can not get the AccessibleObjectFromWindow API to work (and provide a useable object) for the life of me. You know you're in trouble when you search google, and EVERY result is purple instead of blue (indicating you have clicked them already) I have tried sooooooooooooooo many different snippets of code and I am not having any luck. Please help if you can! I'll even PayPal ya $5 (maybe more) if you can help me get it working! TIA

I am 100% lost. My compiler does not recognize "IAccessible" at all, and i seem to be having a hard time finding any further information on it.

That was actually a lot of help. I got the MSAA Explorer from microsoft.com, and it found the address bar, along with MANY other things that SPY++ did not. I am not at home right now to play with it further, but does anyone know of any tutorials for using the MSAA SDK? Thanks again HJB417.

Anyone??? :confused: :o :(

If i understand you properly, i think you will need to get an IDE like Visual Basic .NET or Borland C# Builder, etc...

Hmm, in IE, i would enumchild windows after getting the main hWnd for IE, then use the sendmessage API to set the text of the address bar. In mozilla though, i can't seem to get an hWnd for the address bar. Not even SPY++ or WinSpy can lock on it. Anyone know how i could accomplish setting the address in mozilla? I will also need to be able to get the current address as well. thanks

looking through the fonts, a lot of them are even off centered vertically

Hey, thanks. I tried aerial last night, and it did the same thing, so i didn't think it was the font, but Courier works nicely. Is there a fix? I like the ms font, but alas, i am not totally held down to using "System" style buttons.

I don't think so. "Standard" is also 3D, but that is off centered too. Here's a quick example i whipped up:crap.bmp

Strange problem here. If i create a button (in C# or VB) the text won't TRUELY center unless the "flatStyle" property is set to "System" for that button. Does anyone know why this is? It only seems to do this when the text is so long (for example "Change Account Number"). Try it in your IDE, i am sure it will happen. This doesn't seem promising for a newbie to .net.
