• Dan Wahlin Problem: Can a Form == a Control??

  This is quite an interesting problem (well I think so, but then again, I am a bit strange). I have a .NET 2.0 application that consists of a number of panels that can be dragged around and docked - not unlike the Visual Studio IDE in fact. In these panels I can put any control I care to choose. All well so far. Now then. I have another .NET 2.0 application which fulfils some functional need (as applications tend to do) but it was a bit of a nuisance that it was a separate app. I wanted it to be included as part of my aformentioned panel app. So, after having a look at the object hierarchy for Form, I noticed that it derives from Control. "Yipee!" says I, theoretically I can drop an instance of this entire app as a Contro ...Show All

• caligula Minimum Height for Form?

  I can't seem to get a form of mine to draw at a height of 16 pixels. It always seems to add on an extra 16, I have FormBorderStyle set to None, not sure what's causing this I took a look at this thread and it might give you some kind of answer..

• Josh Robertson error: Unbound reference in aggregate expression

  Trying to add "invoiceTotal" column to Invoice table expression Sum(Child.Total) with "Total" being a computed column on Invoicedetails table expression Price*Qty When I try to configure the tableadapter after adding the computed column to Invoices I get "Unbound reference in aggregate expression 'system,data,aggregatenone'" Any Ideas I haven't used DataSets & DataTables for a while, but I think I ran into this.

• R Raghu How do I set the location of a control loaded at runtime?

  I've created a Button control that I want to locate on the bottom of the form.  How can I use the form's size attributes so that no matter how the form size is changed, the button(s) will always be centered along the bottom of the form At this point, I'm dragging a button control from the tool box and positioning it on the form then, using the button's Location property to use in the code then deleting the button from the form.  I can vaguely remember in VB 6.0 that you would use the form's ScaleWidth and ScaleHeight but these are not in C#. Needless to say, I'm kinda lost. Rhubarb Hi, The Height and Width property can be accessed in the constructor. I tested your code, and it works fine despite the fa ...Show All
