• SQL Server Management Studio Express breaks database connectivity

  Hi, I'm using SQL Express to run DotNetNuke on my own Windows 2003 server. DotNetNuke(DNN) copies a database on to the server from it's installation files and during the installtion process it fills the database with starter data. That process works fine. But the minute I attach to the database in SQL Server Management Studio Express (MSE), my web app loses connectivity to the database. When browsing to the default.aspx, I see the following message: Error Installing DotNetNuke Current Assembly Version: 04.03.05 ERROR: Could not connect to database specified in connectionString for SqlDataProvider __________________________________________________________________ (don't be fooled by the error message, Dot Net Nuke was fu ...Show All

• .NET Development Simple problem with retrieving data

  This problem is so simple, I jus can't see the solution. I am wanting to retrieve data from a textBox on an ASP page and would like to set a default value. < asp : TextBox ID ="TextBox1" runat ="server" ></ asp : TextBox > I initialize the TextBox during page load e.g. in Handles Me.Load as follows: TextBox1.Text = "Default" I later try to retrieve the content of the text box: myString = TextBox1.Text The string loaded into the variable is the original string, not what was typed into the TextBox by the user. I just can't see the solution. Any help appreciated. Hi HerbiNZ! Did you check to see if the page.load-event ...Show All

• Visual Studio Team System Microsoft Project Plan (.mpp file) in Project Portal always locked

  Hi, Was wondering if anyone has seen this problem and possibly have a workaround for it. If we create a project plan using Microsoft Project 2003 (or 2007), publish the plan to the team server and then save the .mpp into a document list in the Project Portal. When attempting to edit the file project always displays the error "The file is locked by another user", read-only, notify, etc.. However the other user is me! Sometimes the error can be avoided by deleting Temporary Internet Files but not always. Curiously this only affects .mpp files that have been associated with a team project and are stored in the project portal. Storing them on the file system, or storing unbound plans in the portal works just fine. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game Loop? WTF?

  Maybe you mean XNA GSE 1.0 Beta2, which we played with in November Microsoft removed Beta2 from their download servers, because it was just wasting space. Also, it would be confusing to still have it pop up when you search for XNA. As far as I can tell, there is no difference between Beta2 and the final version. If you use the final version, and have problems compiling something which was written with Beta2, then I'm sure someone at Microsoft would like to know. ...Show All

• Visual C++ What are all the differences between MFC COM and ATL COM?

  Hi, Did anyone develop Component by using MFC library( in VC6 it is MFC ActiveX Control Wizard(output is OCX) and ATL COM Wizard(COM Component). If yes could you please provide the differences between them and pros and cons of those Anticipating ur reply eagerly, Raa Hi, As i did't find any answer i'm posting here the answers i found related to this Question: Q: What are all the differences among ATL COM and MFC COM development A:Using ATL ATL is a fast, easy way to both create a COM component in C++ and maintain a small footprint. Use ATL to create a control if you don't need all of the built-in functionality that MFC automatically provides. ATL is lean and you can develop thin components downloadable on the web.

• SQL Server dbcc sqlperf in SQL Server 2005

  In SQL Server 2005, the dbcc sqlperf requires View Server State permission. If this permission cannot be granted, how can I find out the nlogpcntused (Percentage of the log file currently occupied with transaction log information) By the way, is there any place that I can find out this kind of difference (required permission) between SQL Server 2000 and SQL Server 2005 Thanks for any help, Peter You could use the query below to get the same information. Note that the information obtained from the catalog view could be inaccurate but it should suffice for most purposes. select (total_size*8)/1024. as LogSize_MB, (used_size*8)/1024. as LogSpaceUsed_MB, (used_size*100)/(total_size*1.) as [LogS ...Show All

• Visual Studio 2008 (Pre-release) Building forms depending on Metadata

  Hi all, I want to build forms, that change their layout depending on metadata. This includes also custom fields and so on. In Asp.Net I could achieve my goal with custom controls (override Render). Since I cannot see anything like that in wpf, I was wondering how this task could be solved I'd be very very glad for an answer! Best regards Peter Ok, let's say I have a form that the user can enter some info. But it can be possible that there are custom-fields that needs to be rendered. The metadata would then describe what custom-fields and of what type the custom fields are and so on... In Asp.Net I was able to achieve this with custom-controls that used the render-method. But how can I achieve ...Show All

• Visual Studio Help Needed to Properly Organize Projects, Etc.

  Hello... We need help/guidance/suggestions on the best way to organize our applications into VSS projects, and then how to use the setup going forward. We have a suite of applications that we sell as one product. So, the product we sell is, for example, named Foo, and Foo is made up of a number of different individual applications, for example, FooBar1, FooBar2, ... Ok. And, there are quite a few applications (.exes, .dlls, .ocxs, etc.) that make up Foo. Additionally, all the individual pieces (FooBar1, FooBar2, etc.) are written in different languages. We have Access .mde applications, we have C++ applications, we have VB 6.0 applications, we have .NET 1.1 applications, and we will soon have .NET 2.0 applications. All these diffe ...Show All

• Visual Studio Team System Different states if the bug is created by a user in the customer group.

  Is it possible to make the states possible depend on who created the bug in the first place If the bug was created by a person in the "firm" group the bug can be closed after internal test but if the bug was created by a person in the customer group it must go throug both internal test and customer test before it is possible to close it. Best regards, Jens As the link suggests there is no way through the work item type definition to change the workflow based on the value of another field. I'll add this suggestion for "dynamic workflow" as a product idea for future versions. In the meantime one option that may be available to you is to write a web service that subscribes to "WorkItemChangedEvents&q ...Show All
