• Visual Studio 2008 (Pre-release) How do I implement the light gray background text in a TextBox?

  Windows Vista has lots of places where text boxes show a light gray info message on the background telling the user what they can enter in that box. The message disappears as soon as the user types something in the box. For example, the search box in explorer windows demonstrates this functionality. The Windows UX guidelines talk about this as well. How does one go about implementing this functionality in Avalon Is there a way to modify the TextBoxBase template perhaps This is what I ended up with... using System; using System.Collections.Generic; using System.Text; using System.Windows; using System.Windows.Controls; namespace MSCAF { public class InfoTextBox : TextBox { public InfoTextBox () : base ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Suggestion: Add detailed error messages to XNA Exceptions.

  InvalidCallException is pretty useless when it contains no detailed information. Right now, in order to see detailed problem information a user is required to have: 1. Visual Studio 2005, 2. Unmanaged Debugging enabled 3. Debug version of Direct3D. No doubt the Debug version of Direct3D would always be required, but isn't there a way to capture the Direct3D error output automatically, and put that information into the Exceptions that XNA throws That would help novice developers tremendously, and decrease the amount of questions on this board as well.

• Visual C++ Memory leak

  I have a method that continuously reads 1MB of data from a hardware in a short period of time. I used a memoryStream data structure for this. In every call of this method, a memoryStream is created and used to read the data, and then it is closed and goes out of scope. These are my assumptions in this implementation: - The garbage collector will free the memory used for the memoryStream when its instance goes out of scope - The allocation for the memoryStream is done from the Large Heap objects, because of their 1MB size Therefore, I expected to see an increase in the memory for a short time until a gc collection of the 2nd generation occurs finally and the memory decreases. However, the result is different: ...Show All

• Visual C++ Is it possible to create a managed DLL and have a program built by VS 6.0 use it?

  I know it's possible to use C++/CLI to create an old style native DLL library that can be used by an application built using VS 6.0. I verified that this works by building a native DLL library in VS 2005. Then I used VS 6.0 to create a test program that uses a function from the DLL and I was able to successfully call this function. But what if we want to use some of the .NET Framework Class Library in this DLL library In other words, can I create a managed DLL and use it from a program built with VS 6.0 Can this be done if the signatures of all the functions only used native types and .NET classes are only used internally by the functions Thanks for any information.

• Game Technologies: DirectX, XNA, XACT, etc. kW X-porter is updated for 3ds Max 9

  I have finally had time to build and test the kW X-porter plug-in to export .X files from 3ds Max 9. This exporter does better than the DirectX SDK exporter (like, it actually does multiple animations), and has a few more bells and whistles than the PandaSoft exporter. Also, with 3ds max 9, the stock IGame.dll file is not overwritten, as the right version is included from Autodesk. http://www.mindcontrol.org/~hplus/graphics/kwxport.html Note: most users claim kW works fine for them, and some users get crashes. I can look at the crashes and fix them if I get a copy of the .max file. The e-mail for questions is found in the installed documentation. OK Mr. Watte, anyway thanks for the attention. I did the update with the version ...Show All

• Software Development for Windows Vista Hosting Workflow Runtime

  We are thinking of hosting the runtime as a static member of a webservice. We’d keep the workflow instance id in the corresponding message. Could anyone see any issues doing so Though this should work, it would probably make more sense to base it off of session id's in your proxy. You can then lookup the corresponding workflow instance and deliver the message based on the session id. I think this provides a more natural, workflow-agnostic experience for the client.

• .NET Development XSLT problems with "cdata-section-elements" and "omit-xml-declaration"

  Hi All, Sorry, this is cross posted from the SQL server reporting services forum here: I'm using some xslt documents to transform the xml output of my reports in sql server 2005 reporting services, but have come across two curiosities where the xslt filter seems to behave unusually. Firstly, I need the final saved file to have an xml declaration, which I believe it should do by default. Even if I put omit-xml-declaration="no" in the xsl:output tag I don't get an xml declaration. At present we have a custom job that writes these declarations back into the xml after SRS has saved it. Secondly and more importantly, I need to have some of my output tags wrapped in CDATA sections. I've tried using the ...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. one way would be to create a dat ...Show All

• Windows Forms Question about docking a control in a panel

  I created a search form in a panel, to be placed in forms: A textbox and a button on top, and a datagridview docked to bottom. I add this panel to my form, and set dock to fill. Then the problem occurs: If the form i add this panel to is higher than the panel, the datagridview will just remain the same size, and stay at the bottom, while the textbox and the button is at top, making a big empty space in the middle. Like this: [TEXTBOX] [BUTTON] ----------------------------- | Dataridview area | ----------------------------- How can i make the datagrid automaticly adjust it's own size, to fill the empty space What i basicly want is to spike the top of the datagrid to right underneith the textbox and button, and whenever ...Show All
