• Windows Forms DataGridViewComboBoxColumn - how do I set the SelectedItem?

  I've added a ComboBox column to my DataGridView, and I'm having trouble specifying, at run time, thet value that is to appear in the combo box, as being selected. I don't need to bind the fields to a data source, I want them to contain two distinct items.  I'm able to add them using "column.Items.Add("xxx")", but when running the app, the combo box is empty, with my added values in the drop down.  What I need is something like "column.SelectedIndex = 0" so I can specify the default seleted item. How can I accomplish this Thanks, John Not quite. I have it working for 2 grids. I created the columns with the following code: private DataGridViewComboBoxColumn CreateDataGridView ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Need a pbuffer overview

  Could somebody please point me to an overview on using pbuffers in DirectX (Or if they go by another name in the DirectX world, please let me know.) Google search is being surprisingly useless, getting details but no overview. In particular, I want to know how to: 1. Render to texture and then apply that texture to something. 2. Render to texture and then read that texture back into main memory. Example code would also be appreciated. Thanks, Ken There is no pbuffer analog in D3D. Actualy OpenGL PBO extention is replica of DirectX mechanism of rendering to texture. Simplest code in SDk that uses this functionality (creating textures possible to set as render target and actually setting them by SetRenderTarget) is Blobs. ...Show All

• SQL Server Bug in Management Studio : Scripting of Publication generates wrong value for @schema_option in sp_addarticle statements

  Hi everybody, I found the following bug in Management Studio: I add an article with sp_addarticle and a value of 0x00 for @schema_option or via the wizard with all article properties set to false. Then I script the publication to a file. The result contains a sp_addarticle statement with @schema_option = 0x0000000000004071, which must be wrong. To prove that I recreated the article with the generated script and checked the article properties. As I feared 4 of the properties ('Copy clustered index', 'Copy nonclustered index', 'Copy unique key constaints' and 'Convert data types') are set to true! Is this a known bug wolfgang Kunk Hi, Thanks for more information. Looks like this issue will only happen w ...Show All

• Visual Basic Selecting data from a combobox

  I can not figure out how to select the text posted in the ComboBox as placed in the ComboBox in the properties window.

• Visual Basic Weird arithmetic overflow

  I have the following function Public Shared Function ReadUInt32( ByVal Array As Byte (), ByVal Index As Integer ) As UInt32 Dim A As UInt32 = CUInt ((0 Or Array(Index + 3)) << 24) Dim B As UInt32 = CUInt ((0 Or Array(Index + 2)) << 16) Dim C As UInt32 = CUInt ((0 Or Array(Index + 1)) << 8) Dim D As UInt32 = CUInt (0 Or Array(Index)) Return A Or B Or C Or D End Function The error occurs at Dim A As UInt32 = CUInt ((0 Or Array(Index + 3)) << 24) The 32 bit value of Array(Index) is &HFFFFFFFF. So Array(Index + 3) << 24 is 4278190080D But it gives an arithmetic overflow even though the value is less than UInt32. ...Show All

• SQL Server Wrong totals in named sets

  Hi In BI Development Studio I create a name set with this sintax: [CATALOGO].[CATALOGONIVEL3].[Tiempo Mantencion] [CATALOGO].[CATALOGONIVEL3] has another two members instead of [Tiempo Mantencion] After that I create a calculated member with this SUM ([SET Tiempo Mantencion] , [Measures].[HORAS JUSTIFICADAS]) It works fine in almost all cells in the cube, but when I ask for the others two members of [CATALOGO].[CATALOGONIVEL3] it does NOT returns NULL it returns the same total of [CATALOGO].[CATALOGONIVEL3].[Tiempo Mantencion].

• Windows Forms Very slow load of C++/CLI project with WinForm

  I have a large C++/CLI project that I'm building with VS 2005. I've added a WinForm to the project that contains some 3rd party components (DevExpress). It compiles and runs, but when I load the project into Visual Studio it takes 5 minutes to start up! Before I added the WinForm it took about 10 seconds. I took a look at what VS 2005 is doing during this time and it's creating 94 folders in C:\Documents and Settings\Fred\Local Settings\Application Data\Microsoft\VisualStudio\8.0\ProjectAssemblies and copying my project's .EXE and .PDB file into each one. Unfortunately, the .EXE is 11MB and the .PDB is 32MB... all-in-all it's copying 3.82Gb of data (4K at a time) which takes a while. Also, if I make any change in the form designer an ...Show All

• Visual Basic Difference Between Basic & Web Developer?

  I hope I'm in the right place -- if not, please redirect. I'm new to all of this stuff, but I enjoy teaching myself different aspects of my website. I have a simple, personal website with several pages -- nothing fancy, but I might like it to be. I'm not afraid to learn. Having that said, I downloaded Expression a while back and recently became interested in the Expression Blend trial version, but when I downloaded it, it recommended Visual Basic or C# be downloaded as well. Once on that site, I saw Visual Web Developer. I ended up downloading both Basic and Web Developer. I had my 'Add/Remove Programs' up because of the warning about .NET Framework and dealing with other previous programs before downloading. Obviously, I was ...Show All
