• Windows Forms How can I call a form's paint method?

  Hi all! I need to redraw my panel, but how can I call the paint method directly 'cause I only made changes on a bitmap, so that paint event doesnt happen.. So, my problem is, that the paint method needs the 2 arguments ( object sender, PaintEventArgs e ), but what is needed to take over Thx! By the way the same question at the other methods, where the 2nd argument's type is just EventArgs.. Using refresh() causes a small flicker on the screen. Is there a way to achieve a refresh or paint update without this flicker ...Show All

• Visual Studio 2008 (Pre-release) databinding with a nullable value

  Hi, I'm trying to bind a property to a combo box wich in the initial state has a nullable value. When I do so, the databinding doesn't work anymore, if I select a value in the combo box it doesn't refresh the property. At first I thought it was my code, but if in the initial state of the property the value is not null, it works fine. Is there a property for the combo box that I forgot The property I'm trying to bind to the combo box is a property from a class I have done. I bind the data to the SelectedValue property in the combo box. ...Show All

• SQL Server Reporting Services 2005 and Business Logic

  I'm working on a app with complex reporting requirement and would like to centralize the business logic for app and reporting. We are not planning to use SP for reporting. Having said that, i would ideally like the reports call the business layer (business.dll) assembly which in turn will call the data access layer (data.dll) assembly to run the required queries and get the results via business assembly as a custom business entity or data set. I'm not sure if this possible with Reporting Services 2005. I have looked at the custom data processing extensions but i dont think it will provide me the required business-data separation unless i'm missing something. I was wondering if anyone has done this before and if yes, could you please pro ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is it better to create a Cue object for each sound or to just Get the cue from the SoundBank each time?

  For part one of my question, I've been working on improving how I'm handling sounds in my game projects and I was wondering which is the preferred method. Is it better to create a cue object for each sound like this Cue mJump = mSoundBank.GetCue("Jump"); and then playing them later by just saying mJump.Play(); Or is it a better practice that unless you need to Pause and Resume a sound that you just Get and play the cue from the Sound bank all the time like this mSoundBank.GetCue("Jump").Play(); For part two of my question, I've been playing with designing my sound management classes using the two different methods and I've been noticing a lot of issues when I try to re-play a sound in a store cue object over and o ...Show All

• Visual Studio 2008 (Pre-release) Emulating glass reflection - gradient or png?

  I have an application and like to run a glass reflection through the background of it (but can't use aero directly because some machines don't support it). My options are to create a gradient or to try and capture the gradient from aero in png form (I am having trouble doing that). Should I use a finely-crafted gradient, or persist at the PNG - and if so does anyone have any ideas (or examples) on how I should do either of these Thanks in advance! Hi Mrmckeb, It seems to me that using the functionality within WPF is better than using a png. There is a walkthrough of how to do this on a WPF/E site available here: http://blogs.msdn.com/wpfedevcon/archive/2007/01/05/Create-a-Reflection-with-WPF_2F0 ...Show All

• Visual Studio Sandcastle and IDL Files

  http://blogs.msdn.com/sandcastle/archive/2006/08/13/697859.aspx#comments States the following: "We are currently looking at the naming convention and will probably rename MRefBuilder to Mreflector for Sandcastle RTW . We also expect the Sandcastle reflection data format to be targeted not only by MReflector , but also by unmanaged reflection tools (for example, a UReflector tool that parses IDL or header files) and SReflector (for generating schema documentation). In order to make it easier for other to target the reflection data format, we plan to supply an XML schema file that defines the format."

• Visual Basic How to Extract Text from Text File 1 Line at a Time

  I'm making a program that will need to open a simple text file, start at line 1, extract line 1 and save it as a string, execute a block of code with that string, and then move onto the next line and do the same thing. I've looked at other topics, but I need something that doesn't just throw all of the data into a list box; it needs to temporarily save the line to a string until the next time when the string is rewritten. To make things simple, perhaps anyone who knows how to make a program that has a textbox and a button on the form can help. When the program starts, it extracts the first line in a text file on the hard drive, displays it in the textbox, and then waits for the user to press the button, at which point it starts the p ...Show All

• Visual Studio Install of Visual Studio 2005

• Windows Forms Mixed assemblies and the designer in VS2005

  Hello, I hope this is the right place to ask this - since i think it is related to Visual Studio 2005, C++ and .NET. I am working on a control library prototype. I use mainly C++/CLI for the development since I have to use some of the non-.NET libraries we have in-house. I have two separate solutions: one is the library project the other is a test bed application. I keep them separate on purpose because I want to model a scenario for testing the controls i have created. Here's what I’ve done so far I created a fancy control based on System::Windows::Forms::UserControl called TestControl. It was nothing but a yellow panel. It was in a namespace called TestLibrary::TestControls. In the test bed solution I referenced the output dl ...Show All
