• Visual Basic ByRef error though parameter is passed by ByVal

  I'm getting an error while trying to fill a grid (third party). The code is as follows: Public Sub FillTheGrid(ByRef one As String, ByRef two As String, ByRef three As String) Dim s As String Dim e As Short = 0 s = (one & Chr(9) & two & Chr(9) & three).ToString e = grdUAH.AddItem(s, 0) <--- Error for this grdUAH.Row = 0 grdUAH.Col = 1 grdUAH.CtlRefresh() End Sub Though there is no value passed a ByRef, I get the error as: Byref value type parameter cannot be null. If I comment out the line e = grdUAH.AddItem(s, 0), there is no error! The stack is as below: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ****** ...Show All

• Visual C# Enumerator on a linked list

  Hello everyone! I'm trying to get an Enumerator to work on a linked list but I'm not sure how to do it. MSDN documentation says that at first the enumerator should be positioned before the first element/node in the collection. Any tips on how to do that in a linked list I thought about setting it to null but then when the MoveNext() method is called I can't do current = current.Next since current is set to null. Should I save the firstNode, then in the MoveNext check if current is null and then do current = firstNode. Seems a little bit messy. Any tips Thanks in advance! -Marlun I believe I fixed it with this MoveNext method: public Boolean MoveNext() { Boolean result = false; if ...Show All

• Visual C# "No source code available for the current location"

  Using VS 2003 C#, XP SP2. I have developed a 'Class Library' but I'm getting the "No source code available for the current location" error message when trying to call a method in the class library for a certain class. My solution contains both class library project but also the windows appliction that uses the functionality implemented in the class library. In the "References" section of the windows application I added the class library as a "Project" referring to the source code directory where the source code of the class library is located. I have deleted all files for all sub projects for the solution and rebuilt it, but still I'm getting the "No source code..." error message when trying to step into method in class library. ...Show All

• SQL Server Install SQL Server 2005 Exp with ToolKit

  Hi, I would like to have SQL Server 2005 Express with the most features as possibles. It seems to be correct about 'AdvancedEdition' but, when I installed the "ToolkitEdition", in order to get "Business Intelligence Development Studio", I was not able to open this option. The file 'devenv.exe' is missed. Do you have some procedure and links to get best set up with theses features for SQL Server 2005 Express Thanks. First, I found "devenv.exe" and I updated the target for the shortcut. It is correct for loading Microsoft Visual Studio, but it is not sufficient because it is impossible to begin a New Projet BIDS: the others associated files are located in ano ...Show All

• Visual Basic Problem in using Try/Catch/Finally

  A textbox(T_TextBox) is bound to a float-type number in a database. The innitial value of the textbox is from that column of the database. I used these codes in my program: Dim T as Double Try T = Double.Parse(T_TextBox.text) Catch MsgBox("Please enter a number for T.") Finally End Try The problem is: every time before I run the program, a message box saying "Please enter a number of T." shows up. This problem only happens at the very beggining. When I change the text later (I select another number from the database, and this is done through a combobox), this message does NOT show up. Anyone knows how to get rid of the msgbox at the begging Thanks, Lili I don't know ...Show All

• SQL Server SQL 2005 Express and Visual Studio 2003 - Connecting

  I have Visual Studio 2003 and had used it successfully with MSDE. I recently upgraded to SQL 2005 Express and cannot seem to connect to the SQL server. it appears in the list of servers on localhost, but when I try to create a new database it tells me that it "cannot create databases on this server." It will not even open up any existing databases. I have .NET 2.0 installed. I uninstalled SQL and reinstalled it, but nothing seems to help. I feel I must be missing something, but do not know what. I no longer have the MSDE installation files, so I hope I can get Studio to talk to SQL Express. Any help is appreciated. Thank you very much for your answer. I used sqlcmd instead of osql, ...Show All

• Internet Explorer Development IE7 Certificate Request/Enrollment

  With IE7, I've noticed the original ActiveX method of generating a client certificate request and installing the signed certificate no longer work (xenroll.dll calling CreatePKCS10() and acceptPKCS7()). How do you do this now with IE7. Vista customers with IE7 don't even have access to xenroll.dll. I have been unable to find much documentation on this change, only that the old way was replaced with "something new", but no details on what the something new is called. Any help would be greatly appreciated! Thanks, Andy Because Widnows vista Microsoft is not supporting Xenroll. For certificate enrollment the windows server uses xenroll active x control. But windows vista us ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. default pool never runs out of memory?

  My app reads in many GB of data, and I have my own cache system that manages raster and geometry data. I've been trying to use D3DPOOL_DEFAULT when creating VB/IBs textures, putting those interface pointers into an LRU cache, and touching a node whenever a resource gets selected into the device. When Create* returns D3DERR_OUTOFVIDEOMEMORY, I release the oldest few D3D resources in the LRU cache, then attempt the Create* operation again. The problem is that Create* never returns D3DERR_OUTOFVIDEOMEMORY, no matter how many resources I create. I have an X1950Pro 256MB on XP64 with current drivers, and I can create about 512MB of D3DPOOL_DEFAULT resources on the card with S_OK being returned every time. After the card's memory gets filled, th ...Show All

• Visual Studio Express Editions Visual C++ 2005 express MFC

• .NET Development P/Invoke DeviceIOControl Failing depending on cdrom status

  Apologies if this should be in the c# forum. Hello, I am experimenting with some basic CDROM control using c# and calling deviceiocontrol. Calling the functions all works fine with one exception: If I send a test device ready command to the drive via SCSI_PASS_THROUGH_DIRECT (CDB of 00 00 00 00 00 00) it will fail upon the conditions of 1. a previously loaded disc is ejected or 2. a blank disc is in the drive. The call to deviceiocontrol itself fails, and Marshal.GetLastWin32Error returns error code 1117 - The request could not be performed because of an I/O device error. While in any other state the call works perfectly and how it should. Similar code I have seen in c++ does an identical thing yet the call to deviceiocontrol succeeds and ...Show All

• SQL Server Random Number procedure problems!

  Hey Guys, I have a quick stored procedure question for you. I created a procedure that returns a randomly generated number. I know there is a built in Rand() function but I need to be able to specify the range. Anyways, it’s returning multiple numbers (1 for each row in the tempTable) But I just want one number returned. I tried using MAX( ) but that’s not a good way of doing it.

• Visual Studio 2008 (Pre-release) There can be at most one address per scheme in this collection.

  When hosting my .svc in IIS, I get the following error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. I know this is caused by sites that have multiple bindings. In my case, I am a web hoster and have sites with multiple host headers per site.
