• Visual Basic Implicit ReDim - Is this a bug ?

  No cracks about the 'bug' is sitting at the keyboard Try this: <Code> Sub Test Dim a(0 To 9, 0 To 5) As String a = FuncX() End Sub Function FuncX() as String(,) Dim Ret(0 To 4, 0 To 5) as String < Code to fill Ret > FunctX = Ret End Function <\Code> When you check 'a' in Test, it has been redefined as Ret: i.e. (0 to 4, 0 to 5) No compile warning ... although I can see where it might be hard to checks this. No Runtime error - except when I try to use 'a' with the full dimensions. Is this a bug or is it intentional and I'm missing something (other than my mind for such poor code consistency).

• Internet Explorer Development get_Document returns NULL in IE7

  Has anyone seen this behavior In IE7, when get_Document is called on IWEBBrowser2, it returns NULL.

• Windows Forms PropertyDescriptor, IsBrowsable and the PropertyGrid

  I have seen this question asked sporadically but have never seen any answers. The abstract PropertyDescriptor class defines an IsBrowsable property that would seemingly be called by the Windows Forms PropertyGrid control to determine whether to display the property or not. This seems reasonable because it is the pattern followed by other PropertyDescriptor properties like IsReadOnly etc. When IsBrowsable is overridden and breakpoints are set in the debugger however, I (and others) have discovered that IsBrowsable never gets called! How then shall we proxy the behavior of the BrowsableAttribute in a custom PropertyDescriptor Are there any workarounds the propertygrid uses a child class of the propertydescr ...Show All

• Windows Forms How to: indicate changed value in DataGridView?

  Hi, In a DataGridView I need to indicate cells having a value changed by the user. At the moment I use the CellValueChanged event to set the cell font to bold upon a change of value: private void dataGridView_CellValueChanged( object sender, DataGridViewCellEventArgs e) { DataGridViewCell cell = dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex]; cell.Style.Font = new Font (dataGridView.Font, FontStyle .Bold); } However the cell should also revert to normal (not bold) if the user happens to restore the original value. Where do I find the original value to compare with Is there a better way Note: the DataGridView's DataSource property is set to a DataTable loaded from a database.

• Visual C++ Get Value of the Program Variable

  Hi, I want to create an application to get the value of the program variable by given paramter in C++, But i don't know how to get the value of those variables. Suppose i make a function void displayVariableValue(char* varName) { int num=10; //Program Variable ........... ............. } If i pass "num" as a parameter varName, funtion should display 10 without accessing num variable. varName has "num" as its value and there is a variable named "num" in the program how can i display value of num variable using varName.
