• Visual Basic Option Strict On disallows implicit conversions from 'Utilities.MessageBox.Products' to 'Utilities.MessageBox.Products'

  This error has me completely baffled. We have a property on one of our UserControls which takes something of type Utilities.MessageBox.Products (we wrote our own message box for the purposes of our program). Public Enum Products As Integer Prod1 = 1 Prod2 = 2 Prod3 = 3 End Enum It is all declared properly, everything has a unique type. The compiler tells me that I should cast it: Me.Sheet.Product = CType(Utilities.MessageBox.Products.Prod1, MessageBox.Products) Which gives me the exact same compiler error on the first argument into CType (how can you get a conversion type error inside a cast at compile time !). Anyway, this makes no sense, something is seriously wrong. Has anyone encountered this before I don't want to turn off ...Show All

• SQL Server Using CASE in WHERE statement

  Hello, This is what I'm trying to do : ALTER FUNCTION [dbo] .

• SQL Server How do I create a Relationship in DB Diagrammer ?

  Hi Folks, When I try to create a Relationship between two Tables I find the Relationship is always created from the Table I start with to itself. I seem to have to select a Table to enable the Create Relationship option, and then when I 'Add' it creates a recursive Relationship to that Table. I guess it must be possible to do what I am trying to do I'd appreciate any advice. Thanks. Barry You need to add at least 2 tables (relationFrom/To). When you have your tables on diagram surface click and drag the key column on to foreign key column of other table. ie: If you have 2 tables: Customers: CustomerID primary key Orders: CustomerID foreign key Click and drag Cust ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Suggestion for stock Vertex structs

  I notice that the framework provides a few stock vertex structures like VertexPositionColor etc. This is cool but it would be great if these could inherit from an interface which provides a mechanism to get the SizeInBytes and Element information abstractly. These structs currently provide this information as static properties but this is no good if you are are trying to write a generic function that can deal with a number of different types of vertex structures seamlessly. My suggestion is that in future something like an IVertexInfo is provided that lets you deal with these concrete vertex structures abstractly.  Perhaps something like this. interface IVertexInfo {     VertexElement [] Elemen ...Show All

• Microsoft ISV Community Center Forums Excel Macro to Capture Live Webcam Image?

  I am attempting to write a macro which will access my USB connected camera, grab a picture, and paste it into an active cell. I am able to do this manually by simply locating the cursor at a cell location, selecting "Insert - Picture - From Scanner or Camera", Selecting the Twain resource for my camera, Selecting Custom Insert, Selecting Take Picture... and viola, the active view from the webcam is placed into a cell I don't expect a macro to do all of this, however, I would like to create a simple keystroke macro that will just bring up the Twain dialog box which has the "Take Picture" button displayed. I have been toying around with the VB objects in the WIA library, but have not yet been able to successf ...Show All

• Smart Device Development hPrevInstance Error Cxx0030

  I hope someone can help me with this problem. I am converting an application from eVC++ to Visual Studio 2005 C++. I was able to fix all the linking errors and was able to build the solution. When I try to deploy the application either to the emulator or an actual device the application starts for a second then crashes. It breaks at afxWinMain(), stating that hPrevInstance is "unable to evaluate expression." Any suggestions would be greatly appreciated. Thanks. The error code that you have mentioned comes when debugger could not obtain the value of the expression. Also, hPrevInstance is always passed as NULL under Win32 world and is not used. Also, I have tried to convert a working default eVC++ application to VS 2005 appl ...Show All

• Visual Basic Multithreading cancellation Methode

  Hi All, Lately I explore about multi threading,because there is a urgent need to implement this feature.I came up with a case of multi threading cancellation. There is two kind of multi threading we have. 1. threading in the program itself. ex.

• Visual C# is as Keyword

  I have a general event handler function. and has a general object passed to it, but I have to use a "is" or "as" to decode the type, is it possible that the base class can detect the type and call the function for that type I don't what to use methodinvoke because it is so slowwwwww. Another apporach would be to anonymous delegates would help but I don't like putting several delegates in one method to handle each type.. and I would have to use continutions to continue the event pump... (ie see robots framework for an example) And I don't want to declare delegates for each type because this means more work for the programmer... void handler(baseobject ev){ if (ev is MyEvent) { MyEvent evmy= (MyEvent)ev); ...Show All

• Visual Studio 2008 (Pre-release) Add IPTC/XMP-Keywords to a jpeg without touching the image itself (like recompression)

  I'd be happy, if someone could help me. I have to add IPTC/XMP Keywords to a lot of jpegs. I found a sample in this forum (Post from RenRen 19 Jan 2007, 9:54 PM UTC ). When I test this sample, the image gets recompressed from 1516kb to 376kb. I would like to keep the image itself untouched. Can anyone tell me, how to get this done A link to a tutorial or a good book would help me as well. Greeting from germany, Florian Having looked around a fair bit - that thread you mentions seems to be the best bet I'm afraid. i.e. it doesn't seem possible via .Net 3 unless there is enough space in the MetaData section of the file.

• Game Technologies: DirectX, XNA, XACT, etc. Video/Animation Playback

  Hi, I'm currently writing a library (for XNA/DirectX) for animation/soundless video playback, and I have a few design questions for the pros out there if you don't mind answering them : I'm having my animation class inherit from game component, and update the frame depending on game time in the overriden Update method, and render it in the overidden Draw method, but even when I preload my textures to render, playback is choppy. Not sure exactly why, but I notice this only when I have significant number of frames (I noticed it with 100 frames, but *not* with 10/15). This problem may be linked and solved by the 2nd point, so please read on. When I preload all the textures for the frames in the animation (and the no. of frames ...Show All
