• Windows Forms Visual Studio 2005

  Hi All when I am trying to discover visual studio 2005, I got a strange behavior when I am trying to put about 50 button on the form and run the application it makes some flicking in the startup I tried to avoid flicking by using DoubleBuffered, see this class InheritedButton:Button { public InheritedButton() { this.DoubleBuffered = true; } } and I had used InheritedButton instead of button also makes the Form itself support the DoubleBuffered and still flickers!!!!!!!!!!!!!! You got some buttons there for a single form., although this is not a limitation, it probably is the reason for your form's flickering when displaying all the buttons, especially because your buttons is DoubleBuffered and maybe owner drawn.

• Windows Forms designer can't load form. Where is 'more information'?

  after going from beta2 to rc1, the designer all of a sudden cannot load my forms anymore. instead, i get the infamous window with the red top that says some errors may go away building the project, while other need code changes. needles to say: the file compiles fine, the form could be opened with the beta2 and vs2003 designers and obviously doing a rebuild doesn't help at all. now what the additional error message says; Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. ok - great. now how do i retrieve the loader exception property. how can i fix this where can i find more info about whats going on   WM_THXADVANCE thomas woelfer http://www.die.de/blog ...Show All

• Visual Basic update dataset schema

  Situation/Sequence of Events: 1) Create a Database. 2) Create a Dataset. Drag database table into dataset. 3) Add queries to TableAdapter. 4) Use tableadapter and dataset in form A couple days later.... 5)Realize I need to make a few changes to the database table. Add new column, change another column varchar length, rename another column for consistancy 6) Now the form doesn't work because the tableadapter cannot load due to the column name change.

My question: How do I initiate (or set it to happen automatically) an update of the typed dataset after making changes to my d ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Finding documentation is strungout like an easter egg hunt!

  Wow. I have just installed beta 2 etc. Started with the 'how to do' info. Have an error in the very first coding example. And went on the hunt. After 24 hours I still cannot find a cohesive document regarding this software. Every where I look points to something else.

It looks like it has spiraled into infinity without an index. Ok, now, If you read this. Microsoft xna and express coders. PLEASE PL ...Show All

• Visual Studio Creating Graphical editors

  Hi All, Im trying to evaluate the possibility of creating an xml editor for VS2005, the editor will need to open xml files but display it graphically, the xmls will represent workflows so the intended editor will look like the Visual studio orchestration editor for Biztalk.

Any comments from your side is appreciated. Thanks !

• SQL Server Installing SP1 problem

  Hi folks I recently downloaded SP1 for SQL Server Express. When I ran the install program, I eventually reached the page where it asked me what features I wanted to install. I chose to do a full install on both the Database Services and the Client Components. Next it asked me did I want to run it against the default instance or a named instance. I chose the named instance option with SQLExpress as the particular instance. Next a page was displayed stating that Database Services 9.1.2047.00 and Workstation components and development tools 9.1.2047.00 were already installed. Clicking on the Details button resulted in a page stating that your upgrade is blocked. It did allow me to click on the next button which resulted ...Show All
