• Specifying a DLL reference

  - by Jesse

  I'm having trouble setting the path to a DLL that is not in the same directory as the executable. I have a reference to dllA.dll. At present, everything is just copied into the same directory and all is well; however, I need to move the executable to another directory while still referencing the DLL in the original directory. So, it's setup like: C:\Original\Dir program.exe dllA.dll dllB.dll dllC.dll But I need to have it setup like: C:\New\Dir program.exe dllB.dll dllC.dl Such that it is still able to reference dllA.dll in C:\Original\dir I tried the following, but to no avail: Set the "Copy Local" value to false for dllA.dll because I want it to be referenced in its original location. Under "Tools Options Projects and Solutions VC++ Directories" I have added the path to "C:\Original\Dir" Added "C:\Original\Dir" to both the PATH and LIB environment variables At runtime, it informs me that it cannot locate dllA.dll Maybe the above steps I took only matter at compile time? I was able to find this http://stackoverflow.com/questions/1382704/c-specifying-a-location-for-dll-reference But I was thinking that my above method should've worked. Any ideas?

• Timeout not working in SQL Connection

  - by carlos

  I have this simple code to test that a DB is ready: Function testlocalcon() As Boolean Dim constr As String = _clconstr Try Using t As New SqlConnection() constr = constr & " ; Connect Timeout=1" If Not t.State = Data.ConnectionState.Open Then t.ConnectionString = constr t.Open() If t.State = Data.ConnectionState.Open Then Return True Else Return False End If Else Return True End If End Using Catch ex As Exception Return False End Try End Function I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored. I search here (Stackoverflow) and internet and found nothing in how to fix this. Any one else have this problem? Or, are there any other ideas on how to let the application know that the DB is ready?

• ASP.NET Custom Control - Template Allowing Literal Content

  - by Bob Fincheimer

  I want my User Control to be able to have Literal Content inside of it. For Example: <fc:Text runat="server">Please enter your login information:</fc:Text> Currently the code for my user control is: <ParseChildren(True, "Content")> _ Partial Public Class ctrFormText Inherits FormControl Private _content As ArrayList <PersistenceMode(PersistenceMode.InnerDefaultProperty), _ DesignerSerializationVisibility(DesignerSerializationVisibility.Content), _ TemplateInstance(TemplateInstance.Single)> _ Public Property Content() As ArrayList Get If _content Is Nothing Then Return New ArrayList End If Return _content End Get Set(ByVal value As ArrayList) _content = value End Set End Property Protected Overrides Sub CreateChildControls() If _content IsNot Nothing Then ctrChildren.Controls.Clear() For Each i As Control In _content ctrChildren.Controls.Add(i) Next End If MyBase.CreateChildControls() End Sub End Class And when I put text inside this control (like above) i get this error: Parser Error Message: Literal content ('Please enter your login information to access CKMS:') is not allowed within a 'System.Collections.ArrayList'. This control could have other content than just the text, so making the Content property an attribute will not solve my problem. I found in some places that I need to implement a ControlBuilder Class, along with another class that implements IParserAccessor. Anyway I just want my default "Content" property to have all types of controls allowed in it, both literal and actual controls.

• Specifying a unique control name when adding at runtime (like the VS IDE)

  - by user316383

  hi, I have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.

• .NET remoting: System references wrong .NET dll, but how to cure ?

  - by Quandary

  Question: I defined an interface like below. The problem now is, that when I add the dll (API.dll) as reference in an asp.net project, it references a wrong API.dll, though I referenced the correct dll. In turn, it doesn't find GetLDAPlookup, but there is another method that is not in defined here, but in an older version of API.dll... I rebuilt the dll I referenced, so it is definitely the latest version that I added as reference. Do I have to add another GUID, or something ? Imports System.Runtime.InteropServices Namespace RemoteObject ''' <summary> ''' Defines server interface which will be deployed on every client ''' </summary> ''' <GuidAttribute("921DE547-32FA-40BB-961A-EA390B7AE27D")> _ Public Interface IServerMethods ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="strMessage">Some text</param> ''' Sub ServerPrint(ByVal strMessage As String) ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="strMessage">Some text</param> ''' <returns>Some interesting text</returns> ''' Function GetLDAPlookup(ByVal strMessage As String) As System.Data.DataSet End Interface End Namespace

• Why Isn't My .Net Object Serializable?

  - by Rob P.

  I've got a 'MyDataTable' class that inherits from System.Data.DataTable I've implemented ISerializable in my class and have a 'Public Overrides Sub GetObjectData...' But when I try to serialize the an object of 'MyDataTable' I get an error saying that 'MyDataTable' is not marked as serializable. If I used a DataTable instead - my code serializes correctly. If I add a serializable attribute to the 'MyDataTable' class - it serializes correctly, but I'm told that is unnecessary if I implement ISerializable. Can someone point me in the right direction?

• Making a workbook visible

  - by JoeB

  I have the following code: Dim DumpXlApp As Excel.Application = New Excel.Application Dim DumpWkBk As Excel.Workbook DumpWkBk = System.Runtime.InteropServices.Marshal.BindToMoniker(FilePath) DumpXlApp = DumpWkBk.Parent DumpXlApp.Visible = True I can't get the DumpWkBk workbook to become visible. Is the issue DumpXlApp = DumpWkBk.Parent line? I don't think it is the BindToMoniker line because I can do things with DumpWkBk.

• VB 2008 - Index was outside the bounds of the array

  - by Jan

  Hey guys I'm having a problem while reading a config.cfg file of my program. I can read the 23. char of the file but I can't read the 24. char (last char in file). This is the code: Dim CFGReader2 As System.IO.StreamReader CFGReader2 = _ My.Computer.FileSystem.OpenTextFileReader(CurDir() & "\Config.cfg") Dim Server(2) As String Server(0) = CFGReader2.ReadToEnd.Chars(23)//This part works If Server(0) = 0 Then Server(1) = CFGReader2.ReadToEnd.Chars(24)//This part results in "Index was outside the bounds of the array". ElseIf Server(0) = 1 Then Server(2) = CFGReader2.ReadToEnd.Chars(24)//This part results in "Index was outside the bounds of the array". Server(1) = 10 + Server(2) ElseIf Server(0) = 2 Then Server(2) = CFGReader2.ReadToEnd.Chars(24)//This part results in "Index was outside the bounds of the array". Server(1) = 20 + Server(2) ElseIf Server(0) = 3 Then Server(2) = CFGReader2.ReadToEnd.Chars(24)//This part results in "Index was outside the bounds of the array". Server(1) = 30 + Server(2) End If And this is the file: Language = 2 Server = 11 Thanks for the answer! Frosty

• When should I implement IDisposeable?

  - by Bobby

  What is the best practice for when to implement IDisposeable? Is the best rule of thumb to implement it if you have one managed object in the class, or does it depend if the object was created in the class or just passed in? Should I also do it for classes with no managed objects at all?

• Variable Binding Class

  - by Davis

  Hi, I believe this is a tough one... I'm trying to create a collection of variable binding in a class. It is intended to look something like this: Dim x as integer, s as string Dim c as new VBindClass x = 1 s = "Hello" c.Add x, s Debug.Print c.value(x) '= 1 Debug.Print c.value(s) '= "Hello" Is there some function that allow us to retrieve a unique ID for a given variable and also get/set based on variable?

• VS 2010 SQL Update for SQL Statement

  - by Mike Tucker

  Please bear with me as I'm just beginning to learn this stuff. I have a VS 2010 Web project up and I'm trying to understand how I can make a custom UpdateCommand (Because I chose to write my own SQL statement, I do not have the option for VS 2010 to auto generate an update command for me.) Problem is: I don't know what the UpdateCommand should look like. Here is my Select: SELECT * FROM Dbo.MainAsset, dbo.Model, dbo.Hardware WHERE MainAsset.device = Hardware.DeviceID AND MainAsset.model = Model.DeviceID Which, VS 2010 turns into: SELECT MainAsset.pk, MainAsset.img, MainAsset.device, MainAsset.model, MainAsset.os, MainAsset.asset, MainAsset.serial, MainAsset.inyear, MainAsset.expyear, MainAsset.site, MainAsset.room, MainAsset.teacher, MainAsset.FirstName, MainAsset.LastName, MainAsset.Notes, MainAsset.Dept, MainAsset.AccountingCode, Model.Model AS Hardware, Model.pk AS Model, Model.DeviceID, Hardware.Computer, Hardware.pk AS Expr3, Hardware.DeviceID AS Expr4 FROM MainAsset INNER JOIN Hardware ON MainAsset.device = Hardware.DeviceID INNER JOIN Model ON MainAsset.model = Model.DeviceID How would I approach updating one column, say "MainAsset.site" if that's changed in the Gridview DDL? Any help constructive help would be appreciated. Thank you.

• Sorting Custom Objects with Parameter in VB.Net/C#

  - by Jeffrey Kern

  Let's say I have a custom object of Foo Is there anyway I can sort through a list of these objects, like list<of foo>.sort() and also be able to sort this list with a passable parameter. which will influence the sort? list<of foo>.sort(pValue) I'm guessing I'll need to define two separate sorts, but I am not sure. Thanks!

• Get information from a higher class?

  - by Clint Davis

  I don't know really how to word the question so please bear with me... I have 3 classes: Server, Database, and Table. Each class has a "Name" property. How I want it to work is that each server can have multiple databases and each database can have multiple tables. So in the Server class I have this property. Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property And I have something similar in the Database class for the tables. This works fine now because I can do something like this to get all the databases in the server. For Each db In s.Databases 's being the server object Debug.Print(db.Name) Next I would like to expand these classes. I want the server class to handle all the connection information and I would like the other classes to use the server class's connection information in them. For example, I setup a server class and set the connection string to the server. Then I want the database class to use serverclass.connectionstring property to connect to the server and get a list of all the databases. But I want to keep that code in the database class. How can I do this? I've attached some code of what I want to do. Public Class Server Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property End Class '-----New class Public Class Database Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _tables As List(Of Table) Public Property Tables() As List(Of Table) Get Return _tables End Get Set(ByVal value As List(Of Table)) _tables = value End Set End Property 'This is where I need help! Private Sub LoadTables () dim connectionstring as string = server.connectionstring 'Possible? 'Do database stuff End Class Thanks for reading!

• Opening up process and grabbing window title. Where did I go wrong?

  - by user1632018

  In my application I allow for the users to add a program from a open file dialog, and it then adds the item to a listview and saves the items location into the tag. So what I am trying to do is when the program in the listview is selected and the button is pressed, it starts a timer and this timer checks to see if the process is running, and if it isn't launches the process, and once the process is launched it gets the window title of the process and sends it to a textbox on another form. EDIT: The question is if anyone can see why it is not working, by this I mean starting the process, then when it's started closing the form and adding the process window title to a textbox on another form. I have tried to get it working but I can't. I know that the process name it is getting is right I think my problem is to do with my for loop. Basically it isn't doing anything visible right now. I feel like I am very close with my code and im hoping it just needs a couple minor tweaks. Any help would be appreciated. Sorry if my coding practices aren't that great, im pretty new to this. EDIT:I thought I found a solution but it only works now if the process has been started already. It won't start it up. Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Dim s As String = ListView1.SelectedItems(0).Tag Dim myFile As String = Path.GetFileName(s) Dim mu As String = myFile.Replace(".exe", "").Trim() Dim f As Process Dim p As Process() = Process.GetProcessesByName(mu) For Each f In p If p.Length > 0 Then For i As Integer = 0 To p.Length - 1 ProcessID = (p(i).Id) AutoMain.Name.Text = f.MainWindowTitle Timer1.Enabled = False Me.Close() Next Else ProcessID = 0 End If If ProcessID = 0 Then Process.Start(myFile) End If Next End Sub

• C# A simple Hangman game

  - by Radostin Angelov

  I'm trying to create a simple Hangman game and i have gotten so far, to make it read all words from a text file, but I don't know how to make the code work for every single word. I have another project, working with 3/4 words but with repeating nested if statements. I want to make it as shorter as possible. This is the code i have so far : using System; using System.Linq; class Program { static void Main() { string[] words = System.IO.File.ReadAllLines(@"C:\Users\ADMIN\Desktop\Letters\Letters.txt"); int LengthOfArray = words.Length; Random rnd = new Random(); int random = rnd.Next(1, 3); char[] letters = words[random].ToCharArray(); bool WordIsHidden = true; char hiddenChar = '_'; char GuessedLetter = hiddenChar; var retry = true; while (retry = true) { Console.WriteLine(letters); letters = GuessedLetter.ToString().ToCharArray(); for (int i = 1; i <= LengthOfArray; i++) { Console.Write("{0} ", GuessedLetter); } Console.WriteLine("Enter a letter!"); char letter = char.Parse(Console.ReadLine()); if (words[random].Contains<char>(letter)) { WordIsHidden = false; GuessedLetter = letter; Console.Write(letters); } else { if (WordIsHidden == true) { Console.Write("You guessed wrong!"); } } } } } Also I'm trying to make the game show each letter, the user has guessed on it's corresponding position, but now the letter is one line higher than the rest of the word and it's not in it's right position. Edited: Here is the result : cat ___Enter a letter! a __ aaaEnter a letter! t aa tttEnter a letter! IF anyone have a clue for where does this come from and how can I fix it, any help will be greatly appreciated.
