.Net And Windows Search (Win 2008 (x86) Server)?
Nov 17, 2011
We have migrated one of our websites from a windows 2003 machine with IIS5 installed.Search within the website also used an indexing service to search within a Catalog "index_pdf".The catalog indexed a folder on the server and Adobe iFilter 6.0 was used to be able to search through the pdf files. While migrating, we switched to another OS -> Windows 2008 (x86). On this machine we installed but now searching through .pdf documents doesn't work. We tested the website on a different server with different versions of PDF iFilters but unfortunatly without any result. Even on a Windows 2008 (x64) server with the 64 bit version of Adobe PDF iFilter we couldn't search through .pdf files.
Our findings:The classic Indexing Service in combination with classic ASP works. (filtering on pdf hasn't been tested)The classing Indexing Service in combination with ASP.NET doesn't work.On windows 2008 servers we have to use Windows Search, because IIS7.x communicates on a different way with the Indexing Service.Now we have to find a way to rewrite our excisting VB.NET code to a way in which it wil work with the new Indexing Service which we don't know to well yet.My question is how to approach this.

We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.

I'm installing Microsoft Search Server 2008 express with a view to indexing some content for an intranet application.
Having not used Search Server before, i am looking at ways of my asp.net app (.net 3.5) querying the search server.
I'm just starting to look into Search Community Toolkit to see if it is relevant to what i want to achieve. But was wondering if you guys can point me in the right direction (code, articles, etc).

We recently upgraded our job server to Windows Server 2008. We have jobs we run manually in a folder (c:Custom Programs). Some programs are console programs others are have a gui. This one program has a gui.It also has a progress bar that shows the progress of the job when you click the go button. Of course it spawns a thread to do the processing. This thread creates a log file to write errors and other things too.
The problem is when the program goes to create the log file an access not authorized error is thrown. I checked the permission on the folder. All users are allowed to create/edit/append/execute. Pretty much everything except take ownership. Also, there's nothing that denies anything. So I see no reason why this isn't working. We can get this to work by using the run as administrator option when we first run the program. However, we don't view this as unacceptable solution. My only thought is the spawned thread isn't getting the same permission set as the program. Am I correct or does something think it's something else.

I have 2 forms in my visual basic 2010 project. Both are connected with an SQL 2008 Server where i keep a db with customers records(name,surname,address, etc).What i want to do is to give certain criteria in the first form, lets say name,and hit a search button. The program should search the db if the specified name exists.If it exists i want to show the results in the second form.By results i mean the name , surname, address,etc. If it does not exist i want to prompt the user to insert data into the db.The problem is that i know how to do this work in a single form but not how to make the two forms "communicate" with each other (meaning that one does the search and the other the projection-adding part).
Edit:I tried setting the filters but all i get is errors. I will post whatever i have written so far in case someone can help me out. So here it is.As i stated earlier i know how to search for the data in a single form(lets call it DisplayForm). As Olivier mentioned i have textboxes for the records, a combo box with the search criteria(name , surname,id) and a Search button that perfoms the search and populates the text boxes. The code for the search button is this:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim intPosition As Integer
'Combo box code
Select Case cboField.SelectedIndex
[code]....
I want this procedure be done in a second form (lets call it FormSearch) and populate the textboxes in form DisplayForm.

I want to search a sql server database from VB.Net and output the results in a Listview. I don't want to use code that involes queries in it, but the queries are to be used in the data set designer, i.e the query builder.Here's what I got so far.
I created a query in the builder called SearchStudent
SELECT FirstName, Surname, Email, PredictedGrade, Notes
FROM tblStudent
WHERE (FirstName LIKE @FirstName) OR
(Surname LIKE @Surname)
Here's the code to search the database and fill the dataset

I am NOT allowed to install into Windows Server GAC. I am allowed to upload my program files to a shared drive, not the operating system drive.To begin, I created a simple Class Library .dll and uploaded the entire project folder to the shared drive. I have absolute permission to do anything with this drive and the computer. This class library has only (1) public property.I created a client exe. with a reference to the shared drive .dll. I do not want a local copy of the .dll into my client folder. I want all clients to use this shared copy on my shared drive. And I repeat, I do not want to install into the GAC. I also have full permissions on my terminal.I have created a key file (.snk) for my .dll, and set up assembly information (public id) and tested.I have tried without key(.snk file), and removed assembly information, and tested.Can someone point me into the direction to install/or not to install a MyClass.dll on a shared driveand be able to reference it from other applications?I do not want to use ASP.NET. This is just a base class. This is not a Web service. It seems Windows server 2003 wants this installed into the GAC (C:WindowsAssembly)I have to be missing something.

I have a windows service written in .net framework 2.0. This service installs and runs perfectly fine on both XP and windows server 2003.We have a new 2008 box that we are migrating over to, so need to get this windows service up and running.When i try to 'start' the windows service on the 2008 machine, i get "Windows could not start the <service> service on local computer. Error 1053: The service did not respond to the start or control request in a timely fashion."I have searched everywhere looking for an answer, and all I could find was a fix attributed to .net framework 1.1 for this same error. That; however, is not applicable here, as the service was written in 2.0.

I have a VB.NET executable program that I've been running nightly as a Windows Scheduled Task on a Windows Server 2003 machine. I have the source code, and it was compiled using VS 2005. Now I want to run it on a Windows Server 2008 R2 machine. If I try to "open" it from Windows Explorer, I get "The version of this file is not compatible with the version of Windows you are running." It is in Program Files(x86), so doesn't the OS know to run it as a 32-bit application? Do I have to load this in VS2008 and recompile it there as a 64-bit app? But all my old VB6 and VBScript scheduled tasks are running fine, why is the OS only complaining about this program?

The configuration is as follows
Remote SQLserver 2005 back-end
Windows Forms Front end (Visual studio 2008)
Is there a way to provide the username and password for the data connection from a Login form and not have it stored in a Connection string? Even better, is there a way to invoke the SQL login window each time the app starts? I need each user to be able to use his own (sqlserver) login everytime the application is started.

I migrated some applications from Visual Studio 2005 to Visual Studio 2010. I develope using VB.NET in VISUAL STUDIO 2010 on a Windows 7 PC (32 bit). The applications writed in VB.NET - VS2005 run correctly in PC having XP, VISTA, WINDOWS 7 and Windows Server 2008. After the migration, the exe of these applications work correctly in PC having XP, Vista, Windows 7 but work stop immediatly on Windows Server 2008. The error returned is 'System.InvalidOperationException'. Seems that the application stop when attempt to evaluate the first global variable that meets. If i change the framework from 2.0 to 3.5, things don't change.

I have written a VB.NET 2008 application, incorporating Microsoft.Office.Interop.Excel, that modifies an existing Excel 2007 spreadsheet. It works perfectly on my WinXP development computer.When I upload the app to a Microsoft Web Server 2008, it opens the file and reads from the file, but when the app tries to save the file, it throws this exception:"System.Runtime.InteropServices.COMException (0x800A03EC): 'july2009.xlsx' is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box."The file is NOT read-only, nor is it opened by any other user or app.The app and the Excel file both reside on the D: (data-only) drive.My first instinct was to look at file permissions. When nothing else worked, I literally created a temporary Group, added EVERY user and security entity to it and granted the group full control of the entire D: drive. No luck.
Then I tried manually elevating the permission by running my app as administrator. No luck.Finally, I copied the file to my XP development computer and ran the app there. Of course it worked perfectly.Can anyone please tell me how to give my program permission to edit a file on Server 2008?

We have a small service shows continuous nonpaged pool bytes increase from the moment it is started. This is only on a 2008 server (all the others work fine).
The service basically connects a socket to a client to see if it's successful and then closes (most code omitted):

Using VB6 to create a file and then open the file just created fails when run on a Vista client with Windows 2008 Server. The same code will work when run directly on the Windows 2008 Server or when using an XP client. If a Sleep 10000 is placed after the close, the program will work. What is the problem here? The code is as follows:
Option Explicit
Private Declare Function GetTempFileName Lib "kernel32" Alias "GetTempFileNameA" _
(ByVal lpszPath As String, ByVal lpPrefixString As String, ByVal wUnique As Long, _

I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]

I'm having an issue with my app where IE will get brought to the front of the screen when I am switching between forms. Basically I have a form with the man menu which consist of a few command buttons that will start up another form once a user clicks on the button. I do not want the users loading up multiple forms in my application, so once they load one form I end up hiding the main form. So my code looks as shown below when a button is clicked.

I'm getting a really strange error. I have a program that needs to run a thread on startup, and for some reason when I do myThread.Start() in Form1() it will crash with "program is not working" (But only on Windows Server, not on my local machine!). However, if I put the same code under button1_Start() it works no problem. What gives?
EDIT A little extra information: In my thread I have a line of code that uses invoke
Invoke(new Action(() => richTextBox1.AppendText(string.Format("Updating {0}..
", DateTime.Now))));
And for some reason the crashing goes away after I make the thread sleep for 2 seconds before it starts executing. Am I using the right method to execute code on the app startup?
