• Windows Forms memory problem with self-removing usercontrols

  I have a Windows Forms application that has a single form which is used to display several different user controls, each containing a set of controls. Only one usercontrol is displayed at a time.  I set up the app to create a new instance of the relevent usercontrol when it is required, adding it to the Controls collection of the form. There is&nb ...Show All

• Visual Studio Express Editions How To Loop On Rows From A Database Table

• SQL Server NEED HELP - Merge Replication with SQL Server 2000

  Hi, I posted about this before, and set out on my own to get this working, and haven't been able to.  I'm trying to get merge replication working with my SQL server 2000, and after 2 weeks I still have nothing.  I've gone through multiple 'walkthroughs' which all brought me to the same point.  I'm getting down to crunch time, and I'm either going to use this or implement my own merge algorigthm (I'd much rather use this).  So here's where I've gotten to: My database it taking snapshots correctly (i think) I believe IIS is configured correctly, because I am able to get to the dll in the snapshot folder I have tried using ...Show All

• Smart Device Development Debug PB compiled with EVC

  Hi, mr. All! Can anybody tell me if it is possible to compile a binary with a Windows CE 5.0 Platform builder's compiler, but debug this binary with EVC Which switches should I set to make it possible Thank you. Unhappily that isn't supported. CE5.0 uses a newer set of compilers and linker that generates debug information in a format that isn't supported by eVC. Note, PB5.0 Can debug eVC generated debug information. VS2005 can debug PB5.0 (and older PB's) as well as eVC generated symbols. So your best bet is you need to debug PB5.0 generated compiler is to use PB or VS2005. ...Show All

• SQL Server Web Synchronization Update (Bug)

  When you try to update a web synchronization, the wizard asks you to select an existing virtual directory. The problem is that it ends up creating a new virtual directory under the one you wanted to update. If you select the original one, the wizard doesn't enable the "Next" button as you'd think it should. David Cornelson Did you select the virtual directory you created when trying to modify I just tried it and it does not create another one. 1) I created a virtual directory called vdir under the default web site. 2) Then I started the wizard and on the web server page, I selected Configure an existing virt ...Show All

• Visual Studio 2008 (Pre-release) Correct way to write an inherited Avalon control

  There are two options in the new class wizard that seem close enough. One is for a Custom control, where a class is generated that's derived from Control, but it's just source code, no Xaml. The other option is a User control, where a class is derived from UserControl, and includes Xaml support. Now, say I want to derive my own ComboBox or ListBox - which of the above two do I use as a start I am thinking, I generate a UserControl derived class, and then replace the base class with the class I want to inherit from. Is that the right approach Or does Avalon have a wholly different model for writing subclassed controls Thanks i ...Show All

• Visual C# The IDE often automatically changes the file subtype from "Form" to "Code" in the .csproj file

  The IDE often automatically changes the file subtype from "Form" to "Code" in the .csproj file, which renders the forms unviewable in design view until that change is undone.  Is there any way to prevent the IDE from doing this automatically Thanks, Wilfred look at this url http://lab.msdn.microsoft.com/ProductFeedback/viewFeedback.aspx FeedbackId=f39a46fc-5dac-4a55-81ef-e1d262fe0040 ...Show All

• .NET Development How i can disable pinvoke?

  I need to deny the use of pinvoke from dinamically loaded assembly how i can do that PInvokes are protected by a demand for UnmanagedCodePermission. There are several ways to remove this permission from the granted permission set. One (as stated already) would be to create a sandboxed AppDomain (the overload with the PermissionSet arg) where you can control the permission set specifically and ensure this is not in the list. Another way would be to have the assembly itself refuse (via the RequestRefuse assembly-level declarative security action) the permission. Brian Stern [MSFT] ...Show All
