• Windows Forms In the form designer I can't access objects which are on an other form.

  how can I access an object being declared on an other form in design time in visual studio .NET For example I have a grid on one form and I wanted to set its datasource to a DataSet table being on an other form. And I also wanted to refer to an image list which is also on the other form. But, I can't. I wanted to do it in design time! Can anybody help me Oh, All my objects are listed at the bottom of the page in the code view. They are private. I can make them public. So, the main deviation from other languages is the fact that the form components are declared at the bottom of the page, rather than the top. I guess this is ok. I'll a ...Show All

• .NET Development ADO.NET 2.0 minimum MDAC requirement

  Hi, does anybody know what is the minimum version of MDAC required to run .NET 2.0 applications Microsoft "recommends" MDAC 2.8 or later for server installations (from .NET framework download page).

• Windows Forms When to dispose of resources

  I have a form that has several datatables declared. These datatables are bound to comboboxes (in code, not drag and drop). Everytime the selectedvalue of a certain combo changes, that filters one or more of the other combo boxes. Now when I close the form, I try to dispose of the datatables, but when I dispose of one, it fires the selectedvaluechanged event of the combo it was bound to and I get an exception. I tried putting the disposal code in form.closed and form.disposed but neither works. Where else can I put it Why are events being fired even though the form is either closed or disposed I stepped through the debugger and it actually ...Show All

  I just upgraded an existing sql server 2000 installation with the RTM sql server 2005 (developer).

  Hi all, Its my first post. i am planning for 315 next week. I have studied MS-Press book for MCSD. please suggest some source for preparation. satyadotsquares@hotmail.com If you are already a good developer, that book should be enough. But I suggest you take the free Microsoft assessments located here: http://www.microsoft.com/learning/assessment/ That will give you an idea of where your weak areas are, then you can aim your studying to particular areas instead of just the general test. Some people also find www.TestKing.com hepful., but I think you should be fine with the study guide and Microsoft assessments. ...Show All

• Windows Forms 2005 RTM: A circular control reference has been made. A control cannot be owned by or parented to itself.

  Well, dang. I had re-done a form that was causing me other problems with the designer. All seemed fine, I went home, and returned to the form this morning to find this: A circular control reference has been made. A control cannot be owned by or parented to itself. This form has a few split containers on it. This instability is very frustrating. Anyone else ever see this Has anyone found a solution to this problem I have VS 2003, 2005, and 2008 and I am getting this issue in all of them. It seems like after five years they would've found a way to keep the designer from doing this, or at the very l ...Show All

• Visual Basic Databinding to a Checkbox

  I have a simple form with 2 checkboxes which are Databound to an object, the properties of which are of type boolean. The problem I have is :- I am using the CheckChanged event. When I check the Box, the value of the UI control is correctly changed, but the value in the object does not reflect the change i.e. the Object seems to lag behind the form. If I subsequently click on another control, and then check the values of the control and the object, they are now in sync. Anyone got any suggestions Cheers, Paul Could you explain how the checkbox is bound to the object In a databound or propertybound sce ...Show All
