• Visual Studio Failed to open report.

  Hi all,   I recently migrated a c# web application from "Visual Studio 2003/Crystal Reports XI" to "Visual Studio 2005/Crystal Reports XI Release 2". I have released the latest build for test and we intermittently experience a problem: the crystal reports work fine and then they fail after a random period. Here is the error information:   Error Message: Failed to open report.   Error Source: Analysis Server   Error Target Site: Void Open(System.Object ByRef, Int32)   Exception Stack Trace:    at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Open(Object& DocumentPath, Int32 Options)    at CrystalDecisions.ReportAppServer ...Show All

• Visual Studio Can't edit macros; "The parameter is incorrect."

  I am getting "The parameter is incorrect." when I try to edit macros. I get it from the context-menu in the Macro Explorer and I get it when I use the Tools menu to get to the Macros IDE. I have also gotten a message saying that an interface is not registered but I forget the details and I cannot get it to happen now. It is highly likely, nearly certain, that I messed it up. I tried to convert a couple of VC 6 macros and messed things up. Now however I can't fix it. I hope we don't have to totally re-install VS. I don't mind losing everything in MyMacros.vsmacros if I must so if someone wants to explain how to do that then that would help. I tried to search for provious answers; if there are any then I don't know what to search for. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. "Indie" Game Development on Xbox 360 and PC

  (This is my first (technically second, I commented on something else) post on these forums) Alright, as a high schooler looking to get into game development after college (or possibly even nixing the college and going straight in) I was wondering if Microsoft was planning on doing anything at all with the XNA Framework that would support low budget game development. How available will tutorials and books about the code be available How much money will the tools and such cost How easy is this code going to be to learn Will it be easy for people to test on PC and a (normal) Xbox 360 with this code I've questioned Nintendo (through their website) about whether or not they'd be supporting "Indie" development, and I was given an aff ...Show All

• Windows Forms Changing underlying datasource and change notification

  I have a typed datarow that I bind to controls through the BindingSource component. For example, BindingSource mysource = new BingindSource(); mysource.DataSource = this.datarow; this.textbox1.DataBindings.Add( "Text", mysource, "TotalCost", true, DataSourceUpdateMode.OnPropertyChanged, null, "C2"); Now I want to change the value of the underlying datasource programmatically but it doesn't update the text for textbox1. this.datarow.TotalCost = 200; How can I tell textbox1 to refresh itself every time the underlying datasource changes Thanks in advance, I think bindingsource was only designed to connect the control and their datasource. The notification of data change should ...Show All

• SQL Server Assigning a lower priority to some users in SQL Server.

  I have a production database used by a web site, and at the same time a group of read-only users who can query the database directly “without the web site” When one of the users runs a complex query, it slows down the server, and affects the web site. Is it possible to change the SQL User account or SQL User Group’s priority to low You know, the same like in the Task Manager and Windows, I can change a process to low, so it will not affect the important processes, can I do this in SQL Server, and is there any workaround. Besides the guessing, does anyone have a real solution Are there sql execution priorities available in SQL Server Or they are just in the deal databases, like Or ...Show All

• Visual Studio 2008 (Pre-release) Orcas January CTP doesn't support .NET 3.0 projects ?

  When, within Visual Studio Orcas January CTP, I try to open a WPF project created with Visual Studio 2005 with WPF extensions, Orcas tells me that this project type is not supported. XAML files seem to be treated like normal XML documents. Are those bits not yet in this CTP There is no support for .NET 3.0 in this CTP of VS.NET, there wasn’t in the previous once either (the once published as virtual machines). And from what I see, it looks like we are 2 years behind in that area, if not more; the early .NET 3.0 additions for Visual Studio were primitive, and the developers in MS there had a year or more to develop them. But that is expected, we were complaining since 2005 about how slow VS2005 is wi ...Show All

• Visual Studio Express Editions Updating listbox items - Must be a simple answer

  Hi, I've been trying to write a piece of code that, will update the value of the current .SelectedItem in a listbox. I am using a CheckedListBox and want the ability to edit the text associated with the currently .SelectedItem. This code will not work: clbCategories.SelectedItem = strCategory The value in the Listbox remains unchanged. I'm sure I am missing something really simple. But cannot figure out what it is. All the examples show you accessing the value not setting the value... Cheers, Roy you can try this: if Me.theListBox.SelectedIndex > -1 then    Me.theListBox.Items(Me.theListBox.SelectedIndex) = " New Value " end if   Another way per ...Show All

• SQL Server Losing config file between child packages and *$##@!- Passwords!

  I have a parent package that uses Execute Package Task against three child packages. They are all setup to use the same configuration file, and the packages are all located in the same folder. Purpose of the configuation is to use the same connection strings for each child package. I removed the path from the config. file specification to facilitate deployment. During debugging, the child packages cannot find the config file when they are run via the parent unless the full path is specified. If run standalone, a child package can find the config. file without the path. As I said, all dtsx filaes and the config file is in the same folder. Also, the password-removal issue is killing me in development. Everytime I touch the config. f ...Show All

• .NET Development Problem with StreamReader

  I'm have a problem with the StreamReader that I can not figure out. As I have it set up right now, it will read through a text document. The text documents are created through our network backup utility. The problem that I am having is that when I run the program I am getting "Object Reference not set to an instance of an object".
