Hello,
I have created a non-rectangular form using a GraphicsPath and regions.
Now, I have code that can move the form, but I do not know how to resize the form.
Do I have to somehow know when the user hovers the mouse over the edge of the form to resize it?
Can anyone help me out?
Thanx a lot

I assume that you are already handling the WM_NCHITTEST message in order to move the form. If so, you need to also define a routine that can detect whether the mouse is in one of the 8 different edge areas of the window. WM_NCHITTEST documentation lists the possible return values. (If you are not handling WM_NCHITTEST, you'll need to do these things manually, but the principles are the same.)

Hello there,
I have a problem : I have to display large amounts of pictures in 1 Container (in my situation a Panel).So far so good...But when I start to zoom on this Panel the Height property can only get to 32767 (because its an int-type). So I can't vieuw the entire content any more... (its parent is a scrollable control)
Also when I zoom out again it seems that i lose some of (or parts of) my pictures that where outside of the reachable area.
Is there a way to solve/go round this problem?
I hope someone can help me...
Greetings Jakke

Generally, when you run into the limitations of the standard control usage, you have to write custom code. I can imagine two major ways around this.
1) Manage the Height property differently, never letting it pass the maximum size. Handle the zoom settings separately, ignoring the items that are not visible. (Probably the easiest solution.) Pay attention to cases where this could cause problems and write code to prevent them.
2) Create a custom solution in which you draw everything yourself, letting you use any sort of number to handle the height and other values. (Lots of work in most cases.)

The API call
StringFormat.SetMeasurableCharacterRanges(CharacterRange[])
will throw an Overflow exception if the CharacterRange[] parameter is greater than 32 elements long. For instance, the following code will throw an exception:
CharacterRange[] ranges = new CharacterRange[33];
StringFormat format = new StringFormat();
format.SetMeasurableCharacterRanges(ranges);
However, if ranges[] was <= 32 elements long, no exceptions are thrown. All of this is regardless of whether each CharacterRange element is initialized (of course, .NET initializes value types anyway). Looking throught the MSDN documentation, I see no mention of a length limit for the .SetMeasurableCharacterRanges method.
So I have 2 questions: is this a known bug or expected functionality? And what other options do I have for retrieving the character positions of text?

The documentation I found is a bit confusing. The VB version of the SetMeasurableCharacterRanges method takes one parameter, an array of type CharacterRange. The C# version takes two parameters:
Status SetMeasurableCharacterRanges(
INT rangeCount,
const CharacterRange *ranges
);
The first being the number of elements in the array pointed to by the second parameter, a pointer to an array of type CharacterRange.
The docs I found doesn't say that either parameter is optional, so I'd start there...

Not sure what documentation you're looking at there, but .NET's SetMeasurableCharacterRanges takes only a single parameter, which is not optional.
I posted this question on an MSDN newsgroup and got the following reply:
We hit the same problem, and basically it is an undocumented 'feature'
To get around this limitation, test each character at a time, or in batches
of 32 characters
James
So it seems this is a 'feature'...?  Really strange why it would be limited to 32 characters.

I wasn't reall impresed with the quality of what I found, but it's in the VS.NET2K3 documentation that came with the Enterprise version. Paste this: ms-help://MS.VSCC.2003/MS.MSDNQTR.2003APR.1033/gdicpp/gdi+/gdi+reference/classes/stringformatclass/stringformatmethods/setmeasurablecharacterranges.htm into the help browser address bar to see what I was looking at. It gives a C# example that takes TWO parameters. It could be that these docs were updated in the Oct'03 update to the VS documentation. I haven't been able to get that update installed...
SetMeasureableCharacterRanges is also not limited to 32 characters, but 32 character ranges.

This type of functionality isn't built into the .NET framework, so you'll just have to use P/Invoke.
Lucky for you, I guy I know from another forum already has done this[^].

I'm learning to deliver some additional functionality to the end user I'm going to have to envoke some transact-sql statements to detach and reattach my SQL-Server (MSDE) database. My C# application uses standard ADO.NET but I can't find any examples of Transact-sql statements be called from within a C# program.
Any hints or an snippet of code on how I would do this from within a C# application?
Thanks,
cb

Search for SqlCommand class. You can run any query or t-sql statement with it.

Thank you sooooooo much, I can hardly wait to give it a try!
Why is it that finding a simple example such as the one you have furnished is so difficult?
Thanks again!

Actually, it's not so bad.
MSDN has lots of good articles on various facets of ADO.Net and if all else fails, there's Google. I would strongly recommend visiting Microsoft's ADO.Net Primer[^] if you plan to work with ADO.Net a lot.
Most of the challenge that I've seen people suffer through with ADO.Net stems from their previous history with ADO 2.x (COM-based).
The two ADO implementations share some terminology and concepts, but are largely different. Many experienced ADO 2.x developers find ADO.Net syntax more cumbersome than ADO 2.x and I suppose I agree to some extent.
A very good place to start is by examining the ADO.Net object hierarchy. Take the time to read about each class (there really aren't that many, and there are only a handful that get used in most common database transactions).
CodeProject is a great place to get information, but you have to have a mindset that you're prepared to explore and experiment - experience is the best teacher.

Agrreed and thank you.
I have bought several ADO.NET books and am picking it up really quickly. I was doing pretty good until I needed to write an application using an MSDE DB on a distributable CD.
In one sense since my application will be just referencing (reading) the DB my work is easy.
The hardwork is in developing a 'setup' routine that installs MDAC, .NET, MSDE, my application and reference the data on the CD.
This kind of through me into using transact-sql, something I've never needed to do before.
I found plenty of examples of transact-sql statements and I've written qutie a few ExecuteNonQuery() routines but I couldn't find an example that put it all together.
What you pointed out was that my commandtype = storedprocedure which I didn't think I needed.
So with your help and my recently purchased "The Guru's Guide to Transact-SQL" I'll get to experimenting.
Thanks again,
cb
