In your connection string, specify the instance as part of the Data Source:
Data Source = \\pathToTheDatabase\mySqlServerInstance
For more information, see the SqlConnectionString docs[^]

If i have a string
[name]MyName[/name]
How do i extract just the MyName part?
|

You could transform the string by doing a Replace('[', '<') and Replace(']', '>') and use XML.

Hi all.
Does anyone know how I can refresh a folder (like App_References) in solution explorer using a macro?
This because I'd wrote a macro that refresh automatically all web references. But after this, the solution explorer don't show web service related files (.dico, .discomap, etc).
The macro:
[code]
Option Explicit On
Imports System
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics
Imports System.IO
Imports VSLangProj
Imports System.net
Public Module Macros
Sub UpdateWebReferences()
Dim vswebsite As VsWebSite.VSWebSite
Dim vswebsiteRefs As New System.Collections.ArrayList
For i As Integer = 1 To DTE.Solution.Projects.Count
'MsgBox(Microsoft.VisualBasic.Information.TypeName(DTE.Solution.Projects.Item(i).Object))
'Change this with full web project path
If "C:\Projetos\Internos\SmartSeguro\Code\Seguro.Web\" = DTE.Solution.Projects.Item(i).Name Then
vswebsite = CType(DTE.Solution.Projects.Item(i).Object, VsWebSite.VSWebSite)
'vswebsite.p()
For j As Integer = 1 To vswebsite.WebReferences.Count
Dim webRef As VsWebSite.WebReference = vswebsite.WebReferences.Item(j)
Dim wsPath As String = Path.GetDirectoryName(webRef.ProjectItem.FileNames(0))
Dim item As New WebServiceItem
item.url = webRef.ServiceLocationUrl
item.nNameSpace = webRef.Namespace
item.dirPath = wsPath
item.serviceName = webRef.ServiceName
item.ReadWsdl()
Dim fs As New FileStream(wsPath + "\" & webRef.ServiceName & ".disco", FileMode.Open)
Dim teste() As Byte
ReDim teste(fs.Length - 1)
fs.Read(teste, 0, fs.Length)
fs.Close()
item.disco = New MemoryStream(teste)
fs = New FileStream(wsPath + "\" & webRef.ServiceName & ".discomap", FileMode.Open)
Dim teste2() As Byte
ReDim teste2(fs.Length - 1)
fs.Read(teste2, 0, fs.Length)
fs.Close()
item.discoMap = New MemoryStream(teste2)
vswebsiteRefs.Add(item)
webRef.Remove()
Directory.Delete(wsPath)
If vswebsite.WebReferences.Count = 0 Then
Exit For
End If
j = 0
Next
For j As Integer = 0 To vswebsiteRefs.Count - 1
Dim webRef As WebServiceItem = vswebsiteRefs(j)
Directory.CreateDirectory(webRef.dirPath)
Dim fs As New FileStream(webRef.dirPath + "\" + webRef.serviceName + ".disco", FileMode.Create)
fs.Write(webRef.disco.ToArray(), 0, webRef.disco.Length)
fs.Close()
fs = New FileStream(webRef.dirPath + "\" + webRef.serviceName + ".discomap", FileMode.Create)
fs.Write(webRef.discoMap.ToArray(), 0, webRef.discoMap.Length)
fs.Close()
fs = New FileStream(webRef.dirPath + "\" + webRef.serviceName + ".wsdl", FileMode.Create)
fs.Write(webRef.wsdl.ToArray(), 0, webRef.wsdl.Length)
fs.Close()
vswebsite.WebReferences.Add(webRef.url, webRef.nNameSpace)
Next
'Implementar: Refresh na pasta.
For j As Integer = 1 To vswebsite.Project.ProjectItems.Count
If vswebsite.Project.ProjectItems.Item(3).Name = "App_WebReferences" Then
End If
Next
Exit For
End If
Next
End Sub
End Module
Class WebServiceItem

A cold start of my application takes about 15 seconds. Further startup takes only 1 seconds.
After a reboot other cold start takes less than 15 seconds, perhaps 3~4s.
I tried to improve cold start by NGEN everything in the installer.
Now I don't know if I make an error or something in the installer but my cold first start time didn't imporve (after I tested it).
Any ideas on what I could do to improve my 1st cold start?

If there are a lot of things loading in the constructor, you could try to postpone those to when the user actually needs them. Furthermore there are tricks like this.SuspendLayout(); and this.ResumeLayout(); that can help improve loading time a little.
Our app has the same problem and we 'solved' it with NGen and postponing loading the comboboxes. Still on older machines loading time takes some time.
hope this helps...
I've found a living worth working for, but I haven't found work worth living for.

Thanks the SuspsendLayout() trick.
Thanks to a link on the microsoft newsgroup (where I also asked the question) I realized that... I should take some time to read NGEN documentation.... 
Some one else, still on MS newsgoup, suggested that just like Office or Adobe, I could have a "QuickStart" application, clever hey!

If you do, give the user a choice about it at install time, and an easy way to change thier mind. I despise having to remove unwanted crap that starts itself everytime I boot my PC.

Yes, there are actually several ways to get to Rome... Oh, you mean something else...you might want to read point 3 in the post "How to get an answer to you question" pinned as the first post in this forum.

I am not angry, just using sarcasm.
Basically there are two reasons to use a decent subject:
1) It increase the likelyhood of the people reading your question are actually the people able to answer it - instead of just a random selection.
2) The forum becomes useless if all subjets simply says "how do i...", "help with..." etc. This means less users and hence fewer answers.
So for your own sake - and for the rest of us - please do not write meaningless subjects.

ofcourse , u are right ,
but actually , I searched in anywhere to solving my problem .
in any case , if u are a developer , it's better to guide us for ur explaining .

I am a developer, but I do not know Crystal Reports (and prefer to keep it that way). I did guide you by suggesting you post in a way so people with the required knowledge MIGHT look at your post.

Hi Friends
This is Sriram working as a Software Engg in Chennai.
I have a requirement that has to access the VSS database.
The functionality must do what ever can be done using VSS client such as Checking out a specific folder or file, Checking in or getting the latest version of a specific folder by the specified user.
All these operations have to be performed through my C# code.
Do any one of u have done such a process or have any idea about it or is there any DLL's available to accomplish this task.
Waiting for the replies
