• Windows Forms Maximize child MDI form without ControlBox

  Visual Studio 2005 Beta 2, C# Maximize mdiChild form without displaying ControlBox ... pretty much says it all. I have set ControlBox, MaximizeButton, MinimizeButton and HelpButton all = False, Set the FormBorderStyle = FixedToolWindow (actually tried them all) and WindowState = Maximize. When I .Show the childForm a controlbox still appears above the titlebar of the MDI parent ... ugly, useless and takes up real-esate better used for displaying data. I provide navigation through ToolStripMenu. I have been trying to create a workaround by sizing the childForm in the mdiParent form's Resize event but I don't know the exact height - titlebar a ...Show All

• Visual Basic Objects and instances

  Hmmm... this is really quite a simple question, but never mind! I want to make a simple game which uses a grid of buttons. Each of these buttons has EXACTLY the same characteristics, but I cant put them all in manually for two reasons: There are 100 buttons to put in most of the time (time consuming!) The user is given the option of how many rows and columns of buttons to put in How do you define the behaviour for a button such as this (ie what code do you use), and how do you add more than one instance of exactly the same button at run time -Javawag   You can create a new button b ...Show All

• Visual Basic ActiveX EXE

  Is there any information on how to build the equivalent of a VB 6 ActiveX EXE in VB.NET. What I need is an application that will manage the writing and reading to an XML file between COM (Word VBA) and a .NET application. Because of the sequence of events both of these application can sometimes clash when reading and writing to the XML file. I can stack file classes in the .NET application to lock and read the XML file but this is not possible in VBA. Locking the file will not work because the XML parser in COM will not be able to read the file when it is locked and stacking file classes in VB is not possible. Another solution would ...Show All

• Windows Forms memory consumption and windows forms

  Hi all, I'm using Visual Studio 2005 and .NET framework 2.0. I have a windows form application in which I load a form that has a dynamic user control array. I may have hundreds of instances of my user control on the form depending on the user. The control is a simple array of text boxes but when I have hundreds of instances it uses several megabytes of memory, up to 20 MB depending on the number of instances. In the task manager, I've noted that when the form loads, the memory being used by the process for my app increases. But when I close the form, the memorty is not released. I'm disposing the form and everything that I can think of ...Show All

• SQL Server Big Log file that won't shrink....

  I have a fairly simple DB, One Log file, one data file, its got half a dozen tables in it that are used for a web based app that allows users to look each other up (think online telephone directory with a few extra bits and you are there), there's a data feed that adds new lines each day as users data changes or new people get added. But this is a couple of hundred or so lines a day, the tables hold about 40,000 data lines as we never delete data just retire it. The problem is the main data file is about 200Mb, the Log file however is 3.8Gb. Now we did import and re-import various bits initially and clear down tables and such. But I don't ...Show All

• SQL Server full text search on views?

    Can we buld full text search on views If yes, can I build a search catalog on a view that allowed both varchar and text columns Hi Abhi, I've asked help for Tony Ting which is full text expert and here are his comments: Answer is yes, but you could only build fulltext on indexed view (materialized view) and column are limited to all available in normal case but not on text/ntext/image/xml column. The later constraint is came from the current limitation that index could not be created on a indexed view w/ text/ntext/image/xml, but fulltext column need a primary index to work on.
