• Visual Basic Save text file with "ENTER" and "TAB"

  Hello, I am using the following codes to save data from a datagrid to a text file. I am a beginer in programming, so it may not be the best way of doing it. Dim DataRow As Integer = 0 Dim DataSaveString As String = "" While DataRow <= 27 DataSaveString = DataSaveString + Me .DataCache.Item(0, DataRow).Value + ChrW(10) DataSaveString = DataSaveString + Me .DataCache.Item(1, DataRow).Value + ChrW(10) + ChrW(13) DataRow = DataRow + 1 End While Me .TempSaveField.Text = DataSaveString Dim TextEncoding As Encoding = Encoding.ASCII File.WriteAllText( "TestFile.txt" , Me .TempSaveField.Text, TextEncoding) End Sub I manage to save the information but ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. TorqueXNA

  I had a look at the XNA version of the Torque 2d engine and noticed that it converted 4mb worth of png files into over 60mb of xna files; Is this a Torque issue or xna as its a massive increase and would make releasing any games online a virtual impossibility. The default processor for non-model (e.g. sprite) textures doesn't use DXT. I just converted my previously mentioned texture to DXT1 and got a 512KB dds file. The same file converted by the content processer to xnb is 4MB. ...Show All

• Visual Studio Team System Dual-server setup / Impossible to specify Database server name in Services Setup

  Hi All, I have been reading all installation readmes and help files and still, I could not manage to go through the setup of VSTS. Here is the situation : I try to install VSTS in dual-server mode, on two distinct Win2003 SE virtual machines, running on one single host. I have the domain users tfsSetup and tfsService, with correct credentials. Data tier has been installed ok. I have SQL Server 2005, hotfixes and TFS database part.

• .NET Development Rounding to X Significant figures

  Is there a function in the class library that will round a decimal to a specified number of significant figures I've had a look a the System.Math object and it doesn't seem to have what I need. I've also seen other suggestions about using string formatting with the ToString method to get the number in scientific notation but I really don't want to go down the road of parsing the resulting string. e.g. 1,234,567 to 3sf = 1,230,000 0.123456789 to 3sf = 0.123 System.Math is all you need. Here's the floating point version: public static double SlideRule(double value, int sigdigits) { if (value == 0.0) return value; bool neg = value < 0; if (neg) value = -value; double m10 = Math.Log10(value); double scale ...Show All

• .NET Development Interop layer throws System Exception (cast) when accessing unmanaged COM code

  I would appreciate help/comments on the following... I am trying to access a COM component written in Fujitsu NetCOBOL from C#. I have spent many hours (days...) reading the docs, trying various combinations, and looking at the samples but my attempts are failing miserably. The COM .dll is called "AVSCOMSVR" and the embedded TypeLib has been picked up and converted to an Interop Assembly by VS 2005. Here's a picture of the generated interfaces and Classes: http://homepages.ihug.co.nz/~dashwood/dashwood/AVSProject2.jpg I find this a little puzzling... VS2005 seems to have duplicated the interfaces, some above the Class entry and some subordinate to it, but that may be OK and just reflect my limited understandin ...Show All

• Visual Studio Team System TFS Warehouse Processing Error

  First up, I have deviated slightly from the stock TFS install because we prefer to use Kerberos rather than NTLM for authentication. To that end, all TFS services and app pools are running under a domain account and SPN's for the HTTP service (both NETBIOS and FQDN) have been registered under that account.

• Software Development for Windows Vista Unpleasant surprise after installing Visual Studio SP1

  Dear all, Beware of installing Visual Studio SP1 if you have Workflow Foundation Extensions for Visual Studio installed. Everything looks ok until you try to create a new workflow. At this point, the binding of activity properties to dependency properties refuses to work. None of the dependency properties appear as valid choices for binding to. Also, the workflow snippets no longer work. There is a simple solution to these woes: Run the Visual Studio 2005 Extensions for Windows Workflow Foundation setup program and Repair your installation. This is not mentioned anywhere in the VS2005 SP1 release notes. Dear Kushal, I'm glad you can reproduce the issue with the workflow snippets. Having created a new Sequentia ...Show All

• Visual Studio Express Editions Profiles vs Sessions Best Practices

  I am currently migrating an application from ASP to C# 2.0. I have designed the c# site to use a session firstname session ID and session Email to reduce the number of hits to the database, and to manage the users state. I recently learned about profiles, and I have attempted to use a profile for the user instead of the session. I am a little confused in how a profile works compared to a session and could not seem to find an abandon or dispose method. Is using a profile instead of a session a bad idea In addtion, I am using a page base class that all pages are inheriting. This class includes a session check to control access to certain pages. I am wondering if it is possible good/bad to use a profile instead of the session, and I ...Show All
