• Visual C++ Documentation for struct RUNTIME_FUNCTION

  I have read the documentation in Visual Studio 2005 Beta 2 for this structure but have noticed that it is not complete.  While it points out that the unwind info address must be a 32-bit offset, it doesn't say what it means when the offset is not to a 32-bit value.  That is, if I run dumpbin /unwindinfo on C:/windows/system32/kernel32.dll, there are many entries that are not 32-bit aligned.  So my question is, what do non-32-bit aligned unwind info offsets mean Bruce: sorry for the confusion: the x64 unwind info in pretty new to me as well. Here's a response I got from one of the linker team: ...Show All

• Visual Basic Add text to a text box from a module

  I'm upgrading a program I wrote in VB6 to VB2005 and am having a problem with updating a text box. I have a module that manages serial port communications. When data is received in the serial port buffer, it should update a text box (txtSerialIn) on a form (frmSerialInOut). Here's the code: Public Sub Handler( ByVal strInMessage As String ) frmSerialInOut.txtSerialIn.Text = strRXData & vbCrLf & frmSerialInOut.txtSerialIn.Text End Sub The text box is not updating with the text that the variable strRXData contains (checked!). This worked fine in VB6. Any help would be appreciated. Thanks. ...Show All
