Calling StreamWriter From WCF
Apr 28, 2011I have a function which works great in my console app. But when I move it over to my WCF, it bombs out every time. Can't figure out what I'm doing wrong. Here's the operation contract:

I am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

I have written this loop to read the result from a stored procedure and write the records out to an excel file. When I look at the spread sheet at least one record is truncated from the original data set.

Dim fs As New FileStream("C:est.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)Dim b As New StreamWriter(fs)
b.WriteLine("hellothere") : b.Close()
b.close is necessary to save changes to the file, but then, fs will be closed, too. is there any method that does the same thing but doesn't close fs, like "b.save"???
Trying to write a series of lines to a streamwriter in ASP.NET 3.5 VB.NET but I get an error 'Object reference not set to an instance of an object.' Here is the code

My goal is to write a write a series of strings in different lines. This seems so simple but I don't see how the reference isn't set; I'm declaring two lines above.

I'm trying to write a CSV file with multiple fields. The data to be written is stored in a list(of string()). Using VB Filewriter.Write for each field, the process is real slow. Isn't there a way to format the data first and use Writeline once for each instance in the data store? Unfortunately, when I created a string with all the fields concatenated and separated by commas, the Writeline inserted quotes around the whole string. How do I prevent this behavior?

Basically all I need is my program to write a character(Ex: "1") in a certain position specified by me in a line in a textbox.
So so far my code is:
Dim sw As IO.StreamWriter = IO.File.AppendText("101.txt")
sw.Write()
And all i need to know is how i pick the position that the .write function writes.
I am using streamreader and streamwriter to read a text file , change the text, then write to the same text file. This all happens in a loop every second or so.Currently I use:
Dim csetpointfileread As New System.IO.StreamReader("C:webcsetpoint.txt")and Dim csetpointfile As New System.IO.StreamWriter("c:webcsetpoint.txt", False)before every file read / write operation, it gets dimensioned every loop. To me this seems like a waste, and should only have to be dimentioned once. If I try to run both statements in the beginning, outside of the loop, the second statement wont work because the "file is allready open". Am I missing something or am I doing it correctly to begin with?
I'm trying to write a file and I have this code so far.

I have this code to send all line of a txt file to a listbox (StreamReader).

I've seen a lot of threads in respect to file access denial, but haven't really found one that suited my particular issue. In my application the part that's not permitting the file to be saved is in the below code. I have 21 text boxes that I'm writing to a file that when in the developmental environment (Visual Studio 2010) works just fine however, when I create a setup program and then install it to a directory I get the infamous "Access to the path 'C:Program Files (x86)Blah, blah' umbers.dat is denied." before uninstalling it I took a look at the permissions on the file itself and ReadOnly is not the issue. I tried looking at the FileIOPermission Class, but find anything that would work for me or perhaps I was doing something wrong. [code]
