• SQL Server Remove identity

  Hi all, Is there a way to remove the identity from a column by using alter table thanx Hi, "disabling" the property does the things behind the scenes I mentioned in my earlier post. In SQL 2k (I didn't check that in SQL2k5 right now) it did a creation of a new table, copy the data to the new table, and renamed the table vice versa to the new / old name.

• Visual Basic Using Graphics to paint on a picture

  I'm trying to add a square to a picture using the graphics member, but they don't show up. Assume that the variable theSelectionRect is a RECT, and is updated in the MouseMove event of the picture box. The rect is basically a 64x64 pixel rect, where the top right corner is the mouse position on the mouse move event. In the code, i clear the previous drawn cubes using e.graphics.clear Then i draw the picture box's loaded image, using e.grpahics.drawimageunscaled. Then, i draw my 'tracking rect', using e.Graphics.DrawRectangle. What is happening is the little rectangles i'm drawing aren't showing up. If i add a line to refresh the picture box, ...Show All

• Visual Studio Express Editions How do I get "TextBox1.Text =" to display to a new line?

  I plan to have a series of GroupBoxes with RadioButtons in them. When the user clicks the "Next" button in each GroupBox, I want to list all of the choices that he made on the screen. I placed a TextBox on the form to hold his choices. (Was this the way to do it ) When I used the " TextBox1.Text = " command to display the choice, the second choice replaced the first choice! When I used the "TextBox1.Text = TextBox1.Text &" command to display the choice, both choices appeared on the same line. I wanted the second choice to appear on a new line. Also, is there a way to pick up the text associ ...Show All

• Visual Studio 2008 (Pre-release) Dynamic type loading

  I'm trying to dynamically load types from a dll and pass the newly created objects through WCF. Is there any way to do this Dynamically load data contracts KnownType attribute I suppose the main issue is the actual method call itself. Since the type isn't known at compile time, I've been using Object, but testing reveals that specifying "Object" then passing a type with a data contract still doesn't work. Any help would be appreciated! Hi! I'm trying to do the same for my type and my config section looks something like this: <system.runtime.serialization> <xmlFormatter> < ...Show All

• Windows Forms Making my form visible to other classes

  Hi, Im writing a program in managed c++ in which there is a class called "World" and a form "Form1" amongst other things. I would like 'World' to have a pointer to my form so it could access properties in that form. So I have declared a static data member in World.h of type Form1 which required me to make a forward declaration of Form1 in World.h. However when my form is created and it tries to pass a reference to itself back to World to hold in the static data member I get the error "cannot convert from 'testproject3::Form1 ^const ' to 'Form1 ^' " Trying another approach I changed the type of the pointer in 'World' to 'Form' and ...Show All
