• SQL Server Distributing database with app

  Sorry if this something beaten to death already... What is/should be required for a target client machine to use and connect to a local copy of a SqlExpress database Can't seem to get a db connection established to a different machine through a VB6 app. Installed the sql native client on the machine, but still can't connect. What am I missing, or do I have to distribute/install the entire SqlExpress client Working fine from my development machine. Rick If you are connecting via TCP/IP you have to enable these protocols. You also have to ensure to enable remote connections. HTH, Jens Suessmeyer. --- http://ww ...Show All

• Visual Studio Express Editions VB 2005 Express and .NET 1.1

  My work environment has a current standard of .NET framework 1.1 on workstations, and no sights set on 2.0 as of yet. I want to use VB 2005 Express... but projects are compiled using .NET 2.0. Is there a way I can use that IDE but my Windows App uses 1.1 for now You have to have VS 2003 to work with 1.1. Do you have an MSDN subscription If you do, you are allowed to install the software at home if you are using it to work from home. Chris ...Show All

• Windows Forms Encrypting the config file

  Hi I've been searching the documentation and these forums to find a way to encrypt the config file, but I cant seem to find a decent solution to this. I want to be able to use all the built-in stuff for configuration-handling, so I use ConfigurationSection.SectionInformation.ProtectSection() to encrypt the stuff I want to protect. But then I need to provide a key for that encryption, and then I need to protect/encrypt that key... Ad infinitum. Some posts here suggests hiding the key in the code, and perhaps also obfuscating this code. This would of course make it harder for someone who really wanted to read my app.config, but not near ...Show All

• .NET Development Cannot invoke web service when using a external SSL device

  I use a cisco 11000 SCA SSL device in conjunction with a Foundry ServerIron load balancer for my web services. I have both Cold Fusion web services (cfc) and .NET web services (asmx) files in my web site. I can invoke my Cold Fusion web services just fine over SSL. But my .NET web services invocation redirects me into an http session for the XML output. The redirection url is not valid, so naturally the XML output is not displayed. Jason I have opened a case with Cisco TAC, but I believe this has to do with the .NET web service internally. ...Show All

• Visual C# How can I prevent others using my assembly?

  How to trust the calling assembly that loads my assembly. I don't want anyother client load my assembly except specific assembly   Sean Vikoren wrote: To get really secure code, you will need to compile to a native format.  Of course when you do this, you loose the flexibility of running in the CLR. The security protections offered by the CLR would also be lost.  Considering that no calling code restriction mechanism is guaranteed to be effective when implemented in native code either, this is hardly worth the trade-off if caller restriction is the main reason for the switch. ...Show All

• Visual Studio Team System Reference Project dll from Separate Solution

  I have a team project with about 3 solutions.  How do I reference the output of a project in a different solution without duplicating the project Yes, that was the information I was looking for, though certainly not the answer I wanted.  :-( I realize this is V1 beta of TFS, but I hope things like this get addressed for V1.1 or V2.  I'm a single developer shop and I'm running into scalability problems such as this already.  I can't even begin to imagine problems a larger shop would run into.  Thanx, ...Show All

• Visual Studio Team System Q: How do you Filter system generated cs files(such as class.designer.cs) in FxCop?

  Anyone tried using FxCop that is capable of disregarding system generated code (cs files such as class.designer.cs) You can suppress individual violations within the generated code, however, there is no way to ignore all generated code. Although, Code Analysis in Visual Studio does shutdown noise on members marked with CompilerGeneratedAttribute and GeneratedCodeAttribute. What exact violations are you trying to ignore I ask this, because at the moment we are starting to work with other teams within Microsoft to clean up warnings within generated code.   ...Show All

• SQL Server Long line of text error

  Hey, After working on a package for a while, I started to get the following error when re-opening the package: "Document contains one or more extremely long lines of text. These lines will cause the editor to respond slowly when you open the file. Do you still want to open the file " What is the problem and if there is fix or workaround Thanks. There is no fix or workaround however don't worry because there isn't a problem either. Its just a VS thing rather than a SSIS thing that's all. I think (but may be wrong) it appears when you have a pre-compiled script task/component in your package. P ...Show All

• Visual Studio Team System TFS Beta3 and MSDNAA

  Hi, Will TFS become available on MSDNAA About 2 months ago i posted some topics on this forum and ms newsgroups about running TFS server on AMD 64 (ADAM cannot be installed on AMD 64) There was no sollution for this issue, unless waiting for BETA 3. So after waiting for BETA 3 to be released i noticed it aint available on MSDNAA ... so i still got the same problem :( I'm not quite sure what MSDNAA is, but to address the AMD 64 question. The TFS data tier will install successfully on a 64bit machine along with SQL 2005.  However, the TFS application tier does not run 64Bit native nor in WoW.&nb ...Show All

• Visual Studio Express Editions Multi Parsing with Regex

  I need help to make a regular expression that extracts particular strings from a target string this is my regular expression right now: [code]border=1></a><br><b>(.*)</b><br>[/code] But the problem with that is that it doesn't just extract everyitem, it extracts one item from the whole target. Allow me to demostrate: if the regex was [code]<b>(.*)</b>[/code] and the target was : <b>1</b><b>2</b><b>3</b><b>4</b><b>5</b><b>6</b> then it would parse out this: 1</b><b>2</b><b>3</b>< ...Show All

• .NET Development .NET Web service call over SSL fails, but IE works O.K.

  We have a .NET web service client application that talks to our server over SSL. Most of the time this works fine, but on some client machines Internet Explorer can hit our web service URL no problem, for example https://ourdomain/Service/sync.asmx , but our .NET application fails to do the same thing. We are experiencing a variety of issues with different internet service providers. Some issues, such as making sure a valid certificate is installed on the client, have been fairly easy to overcome. The one constant in the problems we have been experiencing is that IE never seems to have an issue. So our conclusion at the moment is t ...Show All
