• Windows Forms .NET & WinForms for touchscreen applications

  Hi All. I'm just learning WinForms with C# and I am primarily concerned about creating applications to be deployed on a touchscreen. I have a few questions that I hope somone can shed some light on, point me in the right direction for additional information, or offer any suggestions.  My biggest concern is (semi)transparancy. Ideally I'd like to have semi-transp ...Show All

• Visual C# Ghost Variables?

  I am currently developing an Order Entry application in C#. The order entry process follows a wizard-like format. We have a class, WizardBase, that contains the screen to display. At one point, I had enabled /unsafe code in the project properties. I had also enabled Optimized Code. One of my team members noticed that he couldn't properly declare variables in any function. We tried, and the variable declaration was sporadic at best, most times it didn't work at all. Here's an example of what I am saying: int i = 0; Breaking on this declaration and viewing i in the watch window, would report "i does not exist in the current ...Show All

• Visual Studio Logon failed with Dataset pushed to Crystal Report

  I am using the Crystal Report libraries(9.1.5 dated Sept-Oct 2002) bundled with Visual Studio .NET 2003 to export reports as PDFs or to print directly to network printers from the web server. I am using strongly types datasets as the datasource. After re-installing my application on the web server, my crystal reports throw 'Logon Failed' exceptions for all reports whether exporting to PDF or printing. I have other web applications on the web server that were working before the latest install of this app and now those applications also give the same 'Logon Failed' error. My code is pretty simple: CommercialCrimePolicyDeclaration report = n ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX messes up other Threads!

  This is my situation: In my app I create a new form that renders directx things (simple meshes...)... The DX (DirectX Feb 2006) form starts up it's own render loop, which runs until the form is disposed. On another thread I run a control that displays a graph... When adding points to the control it calculates the DateTime value to it's internal format and then displays the form. If the DX form is disabled (not even loaded) the graph works but if not then the graph doesn't work correctly as it calculates identical values for different dates! Example: without DX: 1.1.2006 20:10 => value 1 1.1.2006 20:34 => value 2 with DX: 1. ...Show All

• Visual C# MessageBox

  I kno I have posted this before, but I didnt get the response I was looking for. I have a messagebox, and when it pops up, I want every part of the computer to be inaccessable until the user presses ok in the messagebox. Can someone tell me how to do this I'm faily new to c#, but from what I've learned you can only make your application inaccessable with a messagebox not the entire computer. Thats what managed code is all about, so that your code doesnt interfere with other applictions. Look into unmanaged code. ...Show All

• Smart Device Development VB Documentation Comments

  In a VB project in VS2005, you can insert triple-tick documentation comments by typing three ticks ('), the comment character. When you do so, VS uses reflection to fill in the documentation outline, including the summary node and nodes for any parameters. An alternate way to do this is to right-click on the class/field/property/method declaration and choose "Insert Comment". However, I'm noticing that this does not work in several VB device projects I have. Typing three ticks does nothing. The Insert Comment menu item isn't even there on the context menu. It seems to always work in brand new VB device projects, bu ...Show All

• SQL Server How to handle multiple column conversions

  I have multiple columns in a table that I only want to convert if they are not null or of the proper type. I don't really want to redirect the whole row if one of the conversions fails, rather I would just not want to do the cast or set it to another value. In this scenario is it better to use a custom script or multiple tasks The multiple tasks seems like a lot of overhead for processing the same data. Just curious how others handle this scenario as it seems as though it has come up quite often on our current project Thanks for the assistance. -Krusty PS: Is it possible to embed evaluation statements along with conversion statements i ...Show All

• Visual Studio Team System Using August CTP of VS2005 WebTest creation hangs.

  I attempt to create a new WebTest using the August CTP of VS2005. Once I hit the OK button VS hangs. If I hover over the VS icon in explorer I see the msg "VS is busy attempting to complete and internal operation". Task Manager shows iexplorer.exe process launched but no sign of IE or the the Webtest recorder ToolBand. If I kill the iexplore.exe process from Task Manager I get control back in VS and an empty Webtest. Any ideas Was this a clean machine Most of the recorder problems we've seen have been the result of registration or GACing problems. Make sure there is only one recorder bar in the GAC and that ...Show All

• Visual Studio Express Editions Namespace missing? + Running from shared drives...

  I am trying to create an application that will send emails in response to given events... however, all of the code examples I've found reference system.net.mail When I try to add the reference (Project, Add Reference...) there is no sign of system.net or system.net.mail Can anyone tell me why this might be missing, or how to get it to appear I am creating a console program if that is any help.   Also, when I try to run my built applications from a shared network drive, they fail to load. I gather this is a 'trust' feature of .net and that this can be fixed using the .net wizards option in Administrative tools. However, wh ...Show All
