When I load my solution and compile it after first starting the IDE, everything works as expected. After changing source and recompiling, I get the following compile error:
Error 11 Unable to copy file "objDebugCAMDRS.Library.dll" to "binCAMDRS.Library.dll". The process cannot access the file 'binCAMDRS.Library.dll' because it is being used by another process. CAMDRS.Library.
After closing Visual Studio 2005 and reopening the solution I can compile again successfully. This is an old solution that has been fine for a long time. I just recently changed computers and reinstalled everything.I am running win XP Pro sp2, Visual Studio 2005 sp1.
In VB.NET or C#, I'm trying to read the contents of a text file that is in use by another program (that's the point, actually, I can't stop the program or it stops writing to the text file, and I want to periodically read out what is currently in the text file in another program)[code]in VB the code is above (a C# answer would be fine as well), however, it still throws the IO exception "The process cannot access the file 'file.txt' because it is being used by another process." Are there any workarounds in this scenario?
View 3 RepliesI have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).
View 4 RepliesI need some input on what I'm doing wrong. What I have so far is an order form program where customers input their information and what they want to buy. Now, what I'm trying to do is take the customer information, store it in an array, write the customer information to a file, and then when I open the order form, it loads the customer information file and automatically fill in a display box on another form with all the customers and the information.I want each customer in a file to be stored on one line. Like so: (Name, address, city, state, zip)
Mike-123 E Dream Rd-Denver-CO-99558
Jane-234 E Code Rd-Seattle-WA-99458
Then when the file is read, to read it, and add each name to a structured array (customers(NumberOfCustomers).Name, customers(NumberOfCustomers).Address, customers(NumberOfCustomers).City, customers(NumberOfCustomers).State, customers(NumberOfCustomers).zip).
After it has all been added to the array, all customers in the file, I want to loop through the array and display each customer on a new line in a listbox, which opens in another form.So far, everything works IF I don't write to a fail. If I store the customers in an array and use a loop to display the customers in the listbox, all is well. However, when writing to a file and trying to read it back into the array is where I've hit a problem. The following code seems to work well, however, it just reads the first line over and over as many times as there are lines in the file, and displays all those using the loop. I just need a way to loop through the lines and store each line into each structured array for each customer, instead of read the first line 12 times over into 12 different places in the array.

I'm trying to delete a file, which prompts the error: "can not delete File in use by another process". I've been researching this for the last couple of days, and have tried every possible suggestion, I've come across, but still keep getting the error. I'm hoping someone might have a suggestion on what I need to change or rearrange in my code to get around this.
The program loads a group of files into a listbox, user selects which files to process, Each file is sent through the sub (process files) to be renamed, and then processed through external programs then removed from the listbox. Each file in the list HAS to be renamed the same in order for the external program to process it. This is where I'm getting the error message, as I need to delete the previous file before renaming the new one. Parts of my code may seem redundant, but its where I was trying every possible scenario of closing the process and or stream that's leaving the file open. [Code]
Lets just say I had something like this:
System.IO.File.Create("C:.txt")
Dim SaveF As New System.IO.StreamWriter("C:.txt")
Under each other. It gives me a error saying:

This MDB (after all operations) is huge (+200 Mb) and needs to be deleted.
To summarize, my program uses a textbox to display the chatroom from a text file on the school network. When someone sends a message, it writes that message to the text box like so:My.Computer.FileSystem.WriteAllText(baseDir & room & ".txt", Message, True)
The baseDir is where the chat files are stored, and the room that the user is in can be altered by the user. created a scroll bar to use so when the chat room reaches a certain length of lines, you may use a scroll bar to view the whole chat. I realized that when someone sends a new message, the scroll bar then jumps back to the top of the text box. Is there any way to fix this, so that it will jump to the bottom each time someone types something new?
Dim lines As String() = IO.File.ReadAllLines(baseDir & room & ".txt")
Dim numLines As Integer = lines.Length

I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.

View 39 RepliesI'm having trouble with reading a file from embedded resources.
I'm starting to learn about developing applications for eBay. You can pass queries to eBay in XML format, and receive replies back in the same format.
I have some examples of code to do this. Here's how the sample code loads an xml file, containing the query.
'Get XML Document from Embedded Resources
Dim xmlDoc As New XmlDocument()
Dim current_assembly As Assembly
[Code]....
I can't see any difference between the sample and my attempt.
The Assembly Name and Root Namespace in my project are both set to "Sample," just as in the original.
I've tried things like changing the filename and the namespace, but I still can't get it to work.
Basically what I want to do is open a .txt file that contains numbers and then read the numbers into an array and sort them highest to lowest but I don't know how.
View 3 RepliesI have an application that currently stores PDF files (and others) inside the database as BLOBs. The trouble with this method is that I've now got SQL Server databases in excess of 200 GB! I've finally figured out a way to still enable full-text search without needing to store the PDF files as BLOBs (yay! Adobe's iFilter isn't great.), but I'm having trouble designing the method for a client to get access to the files stored on the server's file system.
I want to place the files in a restricted directory on the server, so I can't simply pass a UNC path to the client and let them open the file from there either in a browser or using Process.Start(filename). I understand how that would work, but if that directory has user access granted, all sorts of security holes open up, right?So, what I'm thinking about is a way to have a SQL Server account that has read/write access to/from the protected file system directory. That way (in my mind), the SQL Server can take a file as it's loaded in through the import client (as a series of byte chunks) and write the file to that area of the filesystem. Then, when a file is requested, the SQL Server can bulk load the file into a varbinary(max) field and do whatever I want with it.
1. How can SQL Server take a stream of bytes and write them to a specified location on its local file system? (This is assuming that I want the import utility to be able to be run on a client machine and not require it to be run on the server itself.)
2. Is there any way to stream a varbinary(max) file to a web page out of SQL? I'm using a lot of PDF files that will have Fast Web View enabled, so if I can stream the bytes to a web page, the user will be able to see the first few pages of the document while the rest is loading. I thought about having the SQL Server read (bulk load) the file from the protected area and write it to an unprotected area just long enough to point a web browser to that location, then wiping the file, but that brings me back to #1 above and would THEN require me to be able to issue a delete command from SQL.

View 2 RepliesI am having a problem with my program that is desinged to read a 3rd party text file database. I posted previosuly about a problem inserting an item in a new row and the column was expectig a different data type. It appears that sometimes the column is being determined to be of decimal value, I dont understand why. the fields contain information such as
Col1
F123456
CLW-12321 etc....
So my column fills with
123456
12321 the letters just get chopped off
So I added MaxScanRows = 0 to my schema file and that took care of the problem
Except now several of my columns that contain Date Values are coming back
9/24/2010 00:00:00
without the setting MaxScanRows = 0
The date returned 9/24/2010
Here is the code for my schema ini file I am creating:
HTML
Dim fs As New FileStream("Schema.ini", FileMode.Create, FileAccess.Write)
Dim writer As New StreamWriter(fs)
[CODE]............
I have been trying different settings hence the dimmed out lines
Here is the code to fill the datatable:
HTML
[CODE].............
I am thinking that without the MaxScanRows = 0 setting the datatype for Col1 is being incorrectly determined
I am not sure what is happening with other columns that contain date values. Apparently If i use MaxScan Rows=0 all columns are being pulled over as string value which creates numerous problems. If I dont use maxscanrows then all columns appear to be correct except Col21 MLSNUM which is being pulled in as a decimal. Can I change that in the schema file?

Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.
