View 9 Replies[2005] Check If File Is Open?
Jan 22, 2009The following code works to check if a file exist, but I need to also check if the file is open.How would I do that?
If System.IO.File.Exists(Application.StartupPath & "players.txt") = False Or System.IO.File.Exists(Application.StartupPath & "preferences.txt") = False Then
bla bla bla
End if
When the main program is doing it's routine, it is looking at, and using, data from the two files.So, when the user pauses the program by opening the control panel, one or both of the files may still be opened. When the control panel tries to open them, it causes an error.(I am guessing that to just tell it to close them will cause the same problem if they are already closed.)

VS 2005 - StreamWriter Holding File Open?
Oct 2, 2009I'm looping through a csv file. For each line, I'm reading certain values, generating a filename, and writing the record to that file. Here is some logic
If <something that doesn't matter happens> Thendo somethingElseIf File.Exists(strOutFile & (strOutputFileName & "__" & strPrefixFileName & ".txt")) Then
strFullFileName = strOutputFileName & "__" & strPrefixFileName & ".txt" '** Double Underscores after app name
tsOutfile = New StreamWriter(strOutFile & strFullFileName)
[Code] .....
Now, obviously with the above code, there's no reason for the elseif, since they both do the same thing. The problem, however, is if I need to create a new file and write to it, everything works fine. In fact, everything will work perfectly until I need to write to a file that I already created. If I go ahead and just try "tsOutfile = New StreamWriter(strOutFile & strFullFileName)" and point it to the already existing file, I get a permission error (says the file is already open). Is streamwriter keeping an open connection to all of these files that I create? Nothing else in the program is touching these files, only streamwriter.
Here's a quick example to illustrate what is happening
Record 1 goes to file A
Record 2 goes to file A
Record 3 goes to file A
Record 4 goes to file B
Record 5 goes to file B
Record 6 goes to file B
Record 7 goes to file C
Record 8 goes to file A (Error will occur here)

I have decided to save each schedule (AMRN, PMRN, AMTech, PMTech etc) to separate works sheets instead of appending the first worksheet. This way when the shedules need to be printed the whole workbook can be selected to print. When I try to open the existing workbook if it exist I get an error. Here is what I am trying to do.

Adding Data To An Already Open Excel File 2005?
May 15, 2010I am trying to open an excel file and write to it as data becomes availableI can create an instance of excel and write to the selected worksheet once. But, I can't seem to write back to the existing file. I keep on getting a null reference error when I try to send new data to the file.The function I am using will run once, but when it returns to the main form, I lose the values of xlApp and xlWorksheet. It appears that going in to the function makes the original values null.
View 2 RepliesVS 2005 : Clear Tables/Ctrls To Open New File?
Oct 21, 2011I am using TextFieldParser to read a .txt file and create a DataTable I then filter the table and create 4 new tables I then bind those tables to BindingSources Then Bind ComboBoxs to the BindingSource Then bind TextBoxes to BindingSource I like the user to be able to Open a new file without having to close the program So upon opening a new file I have a sub routine that clears the tables the rows and the columns of each table as well the DataBindings to each control The problem is once I do the Text Binding as such
Me.list1_MLStxt.DataBindings.Add("Text", Subject_Values.BindingSource1, Form10.mls_txt.Text)
Then when I open a new file I get an error message conversion from string"""" to type double is not valid.If I never perform the binding I can open and reopen different files without a problem. So this is causing me to think that the problem is with the way I am clear something? But I am obviously not sureIs there something I am missing to clear everything properly in order to open and read and bind a new file?
