• SQL Server How do you pass data to a subreport in local mode?

  I know that to pass data to the main report in local mode you simply use: ReportViewer.LocalReport.DataSources.Add(New ReportDataSource("myDataSource", myDataTable)) But how do you pass data to a subreport inside of the main report I would expect a ReportViewer.LocalReport.SubReports collection or something but I do not see one. Using ReportViewer.LocalReport.DataSources.Add(New ReportDataSource("SubReportDataSource", SubReportDataTable)) did not work You have to pass the data for the subreport in the subreport Event Handler. Example: this .reportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(SubreportEventHandler); pri ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Programming Noobs

  I'm currently going to school for game development and have absolutely no experience with programming or any of the scripting languages. Will the GSE be "beginner friendly" or will I need to obtain some prior knowledge of certain tools in order to be able to use this platform Thanks, 93 Simpler development environment means less control. If you want to do simple platform stuff or 2d shoot'em up, take look at the free, and excellent Basic4GL. It is frustratingly primitive, but you accomplish a lot in a few lines of code. (Btw, it doesn't have procedures, so GoTo and GoSub will be used… Great…) I can't say anything about GSE yet, but creating simple 2d stuff using managed Di ...Show All

• .NET Development Process.GetProcess() Issue

  I'm facing trick problem. I'm using Process.GetProcess( ) method to get all the process which are running in server. This code causes the application termination. If i want to get what kind security permission i have to set . Can any one help Regards Unsure what "find the previous instance" means. Anyway, if you have a semaphore with a maxCount of n, you will be able to call WaitOne and not block n times. After this a call will block, waiting for a Release. There is a timeout overload. If you put 0, you can just check if the count is n or less. ...Show All

• Visual C++ VS2005 float bug?

  I am trying to subtract 3.0 from 3.55 in VS2005 C++ and get the result 0.54999995 The result is correct 0.55, using the same code in Visual Studio 6. HELP !! #include "stdafx.h" int main(int argc, char* argv[]) { float a = 3.55; float b = 3.0; float c = a-b; return 0; } Thanks, yes I have researched and understand the accuracy issue.

• Visual Studio 2008 (Pre-release) Text and vector graphics document generation. How?

  I'm writing a large wizard like application in WPF. As the user goes through different statges of the app I want to generate a document with text, formatting, and vector graphics generated from my visually appealing custom controls. I've got xaml, xps, and WordprocessingML (Word 2007 Beta 2) at my finger tips but I can't bring it all together. I can serialize my controls to xaml, I can put them into a FlowDocument and save out to an xps file, but I can't load the xps file in Word 2007. I can render my controls to bitmaps and generate a Word 2007 xml document that contains pixelated images and text, but I can't put a xaml file into it. I'm feeling a tad disappointed. Has anyone gone down this path and come up with a good solution ...Show All

• Visual C++ Visual Studio and MS Natural Keyboard Pro

  Hello, I have come up on an issue that is really annoying for me. Whenever I press the "Search" button on my Microsoft Natural Keyboard Pro in Visual Studio it opens the "Microsoft Visual C++ Developer Center" homepage in the Visual Studio IDE and it is supposed to run Snoop.exe. I used TweakUI to set the "Search" button to open Snoop (http://grail.cs.washington.edu/software-data/snoop/ - excellent program) globally but for some reason Visual Studio consumes this key press and opens the previously mentioned web page. I've searched through my keybindings and made sure that Help.* and Community.* do not have any keys assigned to them. What else could it be and how do I fix this ...Show All

• .NET Development C# Interop problem with ASP.Net

  I am using DllImport to call the win32 API of our own C++ dll. The API takes pointer to pointer to struct. So I am passing reference of IntPtr to that API and getting the data . I am using Marshal.ReadIntPtr to get each pointer to struct and get the data within the struct. If I call this API from any windows application (console) I am getting the proper output and everything works fine. But incase of ASP.Net, when I call the API from the code behind, the data comes properly but, in many cases the aspnet_wp.exe crashes. When I debug that, I found that till the page_unload of the web page everything works fine, and after that only suddenly the worker process crashes. Thus I felt there can be some problem in deallocat ...Show All

• Visual C# Exception Breakpoint on Application Termination

  I am using C# 2005 Express edition. My application runs fine but on closing I get the following message (for some reason I can't take a screenshot of the dialog) The exception breakpoint A breakpoint has been reached (0x80000003) occurred in the application at location 0x7c90130 This happens in the debug version and release version. My first reaction was that I had left a breakpoint in the program, my second that it is related to the debug version. I am new to C#2005 and could not find any swicth to change the build type from debug to release so don't know if calling for a Build automatically created a Build version. I would like to get rid of it since it would be annoying for my users Thanks in ad ...Show All

• Visual Studio Problem inserting code Snippets

  Hi, I am having difficulty inserting code snippets. When I right mouse click and say Insert snippet I'm told that there are "No snippets available". The same thing happens if I go Edit -> Intellisense -> Insert Snippet.
