Hi,
I've been trying to get the designer in visual studio to work for a class which isn't derived from "form".. It is a class derived directly from System..
I want the designer to work for my class so I can to drag the database connection from the "server explorer". And have it add all the code automatically to my class as is done for classes derived from "form"..
How can I do this??
Your help as always would be greatly appreciated!!

There was a quick "tip" about just this in one of the recent MSDNTV items. (Go to www.msdn.com/msdntv[^], then look at the archive for the one by Juval Lowy.)
Anyway, you temporarily inherit your class from Control (I think), which then enables the designer to do the database work for you. Then you remove the control inheritance if needed.

I'm doing something similar right now actually... Working on creating a GUI library and engine using DirectX that is designable.
You have to implement IComponent in your class (deriving from Component is a quick way to do this) because the DesignerHost (service provided and used by VS.NET) utilizes sites (ISite), which are the basis of components. Then you have to specify an IRootDesigner-implementing class in a DesignerAttribute for you IComponent class. You can try using ComponentDocumentDesigner for that if you don't need any custom designer stuff.
Also check out an article/sample named ShapeLibrary that gives a nice easy example of utilizing design-time services in .NET. You can find it here:

Hope this helps...

Use a foreach loop to loop through the Node's within the treeview.

Hello Gurus,
I inherited a MS Access database. One of the columns in a table happened to name with a SPACE in the middle, "FrameMaker Location". I know, it's not a smart way to name a column.
I was trying to insert some new records into the table. It only worked when I removed the SPACE from the column name (from my code and DB), like "FrameMakerLocation". Otherwise, I got an error like this "Syntax error in INSERT INTO statement".
Do you know any tricks so that I don't have to rename the column name???
Thanks so much in advance
Have a great Thur.
Khang Nguyen;)
Here is my draft of code (roughly)
===================================================================
DataRow row = dataSet.Tables[0].NewRow();
row["FrameMaker Location"] = sFrameMakerLoc;
dataSet.Tables[0].Rows.Add(row);
iNumOfAffectedRecs = adapter.Update(dataSet);

I am trying to write a class to draw an image and then save it to a JPEG.
The drawing is easy, but the saving part is a female dog.
Can anyone help me with ideas on how to do this ?

Hi. I created a dataAdapter and a typed dataset, which refers to a stored procedure that takes an input value. How would I use this dataSet, or fill the dataAdapter, as I dont know how to tell it what the input value must be (which happens to be an int).
