• Windows Forms datagridview doesn't update properly after changing binded table

  <i originally asked this post in a different area, but no answer, so i'm trying a different forum> I'm working on a project that's based off a datagridview that binds to a datatable in an xml dataset. I'm having this strange issue. Basically I update the datatable through code, and I want the changes to be reflected back in the datagridview. This works sometimes, however other times the grid won't update. Usually the grid won't update if I programmatically change a row that is currenlty selected in the grid (but if i go back to the grid, deselect the row and highlight another row, the datagridview will update itself). One way I temporarily got around this was to manually change the row selection before I change the data, but thi ...Show All

I've been looking through the docs and cannot find any obvious way to do this. Can anyone point me in the right direction Thanks. There is no obvious way. You need to maintain your own count. Everywhere you render something add the # triangles to a counter. Clear it every frame. in 3d this means getting ModelMeshPart.PrimitiveCount - or if you are using vertex buffers count them yourself. in 2d assume each sprite.Draw is 2 triangles ...Show All

• Software Development for Windows Vista AudioVideoPlayback problems in C#. Audio, no video.

  I am using Microsoft.DirextX.AudioVideoPlayback in a C# application. I believe I am using the Direct X 9.0c August 2005 version. When I play a movie I hear the sound but I do not see the movie. If I move the form I see a ghost image of the movie behind the form but that is it. The C# code is pretty straight forward and simple so I am not sure what it can be. I tried a ".WMV" file and a ".AVI" file, both of which do the same thing. I can play both files just fine in WIndows Media Player. The code follows. Anyone have any idea string path = GetVideoRoot(); if (video != null) {video.Dispose(); } if (File.Exists(path + videoPath)) { lastVideoName = videoPath; ...Show All

• Visual C# Restrict the size of a string

  This is more then likley going to be an easy fix, but at the moment I can not think straight. What I am tring to do is restrict the size of a string. I am in the process of migrating some data from one sql system to another and need to truncate some text in the process. I need to convert a text field to a varchar(7989), to do this I need to make sure that the data from the text filed is striped so that only the first 7989n characters are returned. I have a data reader that I am going through and am adding it to a genieric collection that I am then going to process and re insert into the new system... all I need is a way to restrict the text returned from the data reader... all the rest is fine. won't the following work for you ...Show All

• Visual Studio Tying domain classes to shape objects

  Hello! Please forgive me for such a beginner question, but we just started playing with DSL Tools a few days ago and are having some trouble getting shapes to appear in the VS toolbox. We've attempted the following steps: create a domain class ('FooElement'), create a Geometry Shape ('FooShape'), add an Embedding Relationship from ExampleModel to FooElement.  In the DSL Explorer:  add a ToolboxTab/Tool (Class=FooElement, Order=10), add a ShapeMap (Class=FooElement, Shape=FooShape). After performing these tasks, the item still won't show up in the VS toolbox when running the project.

• Windows Live Developer Forums Invisible DIV over pushpin

  I'm trying to use custom pushpins with my own popup which is a DIV tag with details in it. I'd like to mimic the effect of mouseover the pushpin and have the popup(DIV) disappear. I read someone's suggestion re: placing an invisible div over the pushpin that has been clicked That way I can hide the DIV with the details when the user does mouseout over the invisible div on the pushpin. I have the x, y coordinates of the pushpin, but the DIV placement is relative to the window, right I'm confused on how to associate the DIV placement to the x, y coordinates on the map, and to adjust accordingly. thanks in advance.
