• Visual Studio Tools for Office ListObject bug or something silly?

  Hi there, I'm hoping someone can tell me if I'm doing something stupid or this is a bug. I have 2 list objects on a single worksheet. Each is bound to an array (2x different arrays of the same class) via a BindingSource object. The array class has about 10 string members, each which has a property to get/set it (I'm assuming this is how the DataSource knows what columns to fill in on the list object etc). So anyways, 2 list objects using a different datasource object each, but each datasource points to an array of the same class, but different values. I have a button that I click which sets the datasource of each BindingSource object to each array (which fills the listobject as the listobject has its datasource set to this BindingSource ...Show All

• Visual Basic FormClosing Event

  Hi there. I have an inherited form hierarchy where the root form captures the FormClosing event, which then invokes a overriden "FormClose" method. The overriden method correctly determines the value of the e.cancel attribute and passes it back to the root FormClosingEvent handler. However, when e.cancel = true the form closing event is not canceled and the form closes anyway. The root form, and all it's children, are children for a MDI form. Can anyone tell me why e.cancel = true in the case doesn't prevent the form from closing Thanks. Here is the declaration of the FormClosing Event handler: Private Sub StandardUIForm_FormClosing( ByVal sender As Object , ByVal e As System.Windows.Forms.FormClosingEve ...Show All

• .NET Development Generic performance... benefit?

  Hi, in every article about generics is written that they improve performance because no boxing, etc. occurs. So I wrote this simple test code and was astonished that the non generic part actually performs a couple milliseconds faster than the generic part About 59.8 seconds for the generic and 59.1 seconds for the non generic (avg. of 10 runs). Am I missing something here [code] using System; using System.Collections.Generic; using System.Text; using System.Xml; using System.Collections; namespace ConsoleApplication6 { class Program { static void Main(string[] args) { string s = ""; Test<string> test = new Test<string>("hi"); DateTime start = DateTime.Now; for (int j = 0; j < 1000000; j++) { foreac ...Show All

• SQL Server SUBSTRING with multibyte codeset

  SELECT SUBSTRING(fieldOne, 1, 4) FROM tableOne; For the above statement, I want to get EXACTLY four bytes. However, if fieldOne contains some multibyte characters, it will return more than four bytes. I don't have too much experience in SQL server. Any solutions/suggestion will be appreciated. Thank you. Start and length for character data type values specified in SUBSTRING refers to number of characters. So this is expected behavior. You could convert the string to binary data and then use SUBSTRING. But this may not produce the correct results for Unicode data or in other words you may get truncated results when you try to convert from binary to nvarchar. See BOL topic on SUBSTRING for mo ...Show All

How to i pack it up so i can take it to a different computer and edit the code Instead of just copying the files - Do a click once deployment to CD. This will create a proper deployment setup which you can then run on other machines - one of the requirements in the deployment will be .NET 2.0 Framework so if its not on the machines it will install it.

• Internet Explorer Development IE7 icon Problem

  Firstly, let's clear up the icon definitions. Favicons are those that are downloaded from the linked website and show the websites logo or whatever. The icons that we are all concerned with here in this fourm that are in error are the windows icons. These icons along with an array of others are usually contained in system dll files. Indexes into these files are kept track of in the registry and in the shortcut or favorite itself under properties. For example if the dll has 256 icons and windows calls the dll as shell.dll, 255 the 255 is the index into the icon file. In this case the last one (base 0). The problem here is with IE7. The registry entries under HKEY_CLASSES_ROOT (url and internetshortcut) appear correct. I ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Using .X files for world model

  In my game, using .X file format for objects in the world (players, health pack etc...) is okay. Right now, my game doesn't have a detailed world. When it does have a detailed world, can I use the .X format for the entire world One .X file for a huge level or part of the level If I use it, Can I get the individual triangle vertices from the mesh Using one or more .x files for the level is up to your choice. The two solutions will work. You can get vertices from a mesh using ID3DXBaseMesh interface and LockVertexBuffer function. You'll have to use the vertex declaration obtained with ID3DXBaseMesh::GetDeclaration or GetFVF functions to understand the vertex buffer layout. Triangle indexes can also be fetched using the ID3DXBaseMesh ...Show All

• Visual Basic array of controls..

  is it possible to create array of controls in UI.. i need to create array of buttons (as similar to VB6) is there any way to do this I'm hoping to do something similar to what the op was asking about. I'm fairly new to VB, so forgive the ignorance. Once I get this simple thing going, I'll work it into what I really want to do. Simply put, I'm trying to create an array of 5 buttons on a form. I'm hoping that having this code in the form loader will create those buttons, but nothing appears on the form when I run it.

• SQL Server Create Customer Ranking in Cube

  Hey guys, is there a way i can create a Rank Member or measure in my cube based on sales for that customer, no matter what time heirarchy we are looking at. I have reporting requirements where they want to see all customers, ordered by Sales Amount. It could be at a year level, month level, or even a week/day level.. Im new to SSAS and MDX, i have looked at a few examples posted here, but cannot work out where i put the script in my cube. Is it a measure or do i do it as a calculated column in the DSV. Any help is much appreciated. Thanks Scotty Thanks Mosha.. this worked great..

• Game Technologies: DirectX, XNA, XACT, etc. Multi-texturing a mesh

  After some fruitless searching I have found no clear answer to a multitexturing problem I have. I figure it must be so straightforward that no one has bothered to write it down. How can I apply multiple textures to a mesh, with different textures associated with different vertices My particular problem is related to a terrain engine, but I will reduce it to a simple example. Suppose I have a mesh of 4 vertices (ie 2 triangles); I also have a map-type file (a .tga in my case) whose values indicate which textures should be applied to each vertex. So: (0,0) = grass (1,0) = stone (0,1) = earth (1,1) = water Do I declare which texture should be used when the vertices or mesh are created Is this done during the rendering, and i ...Show All
