Ivan. How much memory is your System Idle process using It shouldn't be much at all, since all it's doing pretty much is minor bookkeeping. There is no way whatsoever that it should cause any program to not run. System Idle is what happens when nothing is happening. Computers cannot just rest, they must always be doing something, and that's why System Idle is there. I have found out that there are several items that run in the system idle process, they are ...Show All

• Daffodils Unbound DataGridViewComboBoxColumn - strange error

  It doesn't seem like it should be this hard to do this, but for some reason it's just not working out. I have a DGV to which I am adding rows. One of these columns is a ComboBox Column (DropDownList style). The values in this combo box come from an enumeration I've defined. I am using the following code to set the items in the combo box, and to add a row: Dim combo As DataGridViewComboBoxColumn = DirectCast (DataGridView1.Columns( 0 ), DataGridViewComboBoxColumn) combo.DataSource = [Enum].GetValues( GetType (FilterType)) ... DataGridView1.Rows.Add(theFilt.FilterType, theFilt ...Show All

• RussP DataGridView Column Header Cell Style not working

  The backcolor for row header and column header does not work. e.g. Grid.Column(0).HeaderCell.Style.BackColor=Color.Blue Grid.Rows(0).HeaderCell.Style.BackColor=Color.Blue Grid.TopLeftHeaderCell.Style.BackColor=Color.Blue You could always just remove the theming on the headers. Set EnableHeadersVisualStyles to false and the header coloring will be honored. -mark Program Manager Microsoft This post is provided "as-is" Sorry you will have to draw the column or row headers yourself if you want to change the color.

• Inferno986 ClickOnce deployment - bootstrap Install Check

  We are planning to use an executable along with Bootstrapper to handle installation checks with ClickOnce. I dont see any option to specify the install condition for the application that is deployed, even with the bootstrapper I can just specify the install condition for the prerequisite bundled along with the application getting deployed. So we have decided to make a dummy installable and attach an external executable (InstallConditionChecker) that could do the installation check and return the appropriate exit code so that the installation can bypassif install condition are met / halt. like dotnetchk.exe that does the prerequisite check before installation of dotnetframework. We want to have some executable that can do the prerequisite ...Show All

• Sen_p_kumar Defaulting Values

  Hi gang, Every once in awhile I get to ask a question instead of just answering them. I know that in my sub-classes for controls such as TextBoxes, I can avoid having the IDE stick extra code in the "IDE-generated" code for properties by setting a DefaultValue in the TextBox sub-class. Like this: public class MyTextBox : TextBox { private string m_MyProperty; public MyTextBox { this.m_MyProperty = ""; } [DefaultValue("")] public string MyProperty { get {return this.m_MyProperty;} set {this.m_MyProperty = value;} } [DefaultValue(typeof(Color), "Window")] public override Color BackColor { get {return base.BackColor;} set {base.BackColor = value;} } ...Show All

• joyedele Form Ownership Problem

  Hi We are developing a Winform application on Visual Studio 2003. I have one problem, I am not using the MDI concept, I have used plain non MDI form, I have menus on the left hand side, I open one form I set the owner ship of the new form to the main form. When ever I minimize or close both the forms are working as expected.

Nothing happens to it. What I want is all open forms should min/max when ever I min/max the main form. Can anybody guide me as to how do I do this. I am writing my code in ...Show All

• dazza33 TypeDescriptionProvider attribute is ignored with generic Form

  I am trying to create a generic form that can be designed in the VS designer. I found an article (http://www.urbanpotato.net/Default.aspx/document/2001) that fixed this for an abstract form and now I am trying to do the same thing with generics. But it seems that the TypeDescriptionProvider attribute is ignored when the Form is generic. The message box does not popup when I enter the designer (and of course the form cannot be designed). But when I remove the <T> from the generic form (and the <object> from the derived) the message box popup! Shouldn’t it always popup even if the class is generic or am I missing something Here is my GenericForm: [TypeDescriptionProvider(typeof(GenericFormProvider))] public class GenericForm< ...Show All

• rjo2 Dataset & DataGrid???

  I have a dataset that holds some data, and when i show it in the data grid i would like it to be editable, and changed in my dataset, can anyone send me a link or shed some light on how i should get this done do not use acceptchanges() otherwise when you update, it will not update the changes to the database since the rows modified in the dataset have been marked to "not needed to be updated" Remember, you need to rebind the datagridview after you have done an update() - do you see the updates commited in SQL Server database/table To be safe for now, I would suggest you comment out the SqlCommandBuilder and just do an Update() directly after making sure that your SqlDataAdapter has the SqlCommand in its constructor a ...Show All

• Alessandro Camargo Creating a Table Adapter from Access DB wrong date format

  Hey all. In my Access database the date format is dd/mm/yyyy but when I create a table adapter from my access db table it loads the date as a full time + mm/dd/yyyy format. An example from one of the rows: In my database the row has a date column which represented as 14/1/2007 and at the table adapter it returns the date as 11:07 AM 1/14/2007 and all the controls which are binded to this tableAdapter return this format.
