View 1 RepliesThis has got to be one of the most frustrating issues with asp.net. I first got the error parser error cannot load default and as I have done before checked if the naming was correct in th bin folder and made the changes accordingly. Now I get the following error:
somethiing._DEfault is not allowed here because it does not extend class 'System.Web.UI.Page'
where something is the name of the project in the properties. I have the following code in Default:
Namespace FormDiscovery
Partial Class _Default
Inherits System.Web.UI.Page
Shared settings As New System.Configuration.AppSettingsReader

Now I have deleted the project and other in the solution and created a new one and still this error and if I take the 'something' name away I get the cannot load default error.
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.

friend of mine has no HTML knowledge so I'm attempting to write a program that replaces certain parts of a html file to suit his needs.I've edited the HTML file and marked certain parts with "tags" like this:
#IMAGEURL1# I have a textbox where he can copy + paste an image URL and hopefully the #IMAGEURL1# is replaced with the contents of the textbox.
So can someone please enlighten me to-as how to open a HTML file (there's no textbox to display the contents just yet, I'll add one if needed), find the specified text and then replace it with whats in a textbox.

I need it so that it keeps adding on to the lines which it has already created. If i dont use a loop it will just keep replacing the same line.
I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

I am loading a dataset with a csv file.I remove the quotes around each field in the csv file and I am splitting each field wherever there is a comma:Dim fields() As String = lines(i).Split(","c) The problem is that some of the fields have a comma in the csv file (surrounded by double quotes).How do I replace those commas with a space to avoid problems when loading the dataset?
View 18 RepliesI decided to use XML to handle some of my configuration chores. My XML file looks something like this:
<catagories>
<catagory path= "C: empwyoming" name="Wyoming">
<URL Filename="Picture1.jpg">http://www.domain1.com/pic.jpg</URL>
<URL Filename="Picture2.jpg">http://www.domain2.com/pic.jpg</URL>
[code]....
I'm wanting to manage this list in my program. Currently, I have written code to read the catagories into a combo box, and once a catagory is chosen, I can read the children URL nodes into a listview. I want to allow editing and re-arranging of the URLs in the listview, and I'll have no problems with that. So my question is, what is the best way to dump the listview back to the xml file? You should consider the contents of the listview as a replacement for ALL of the existing children in the XML file.
So i have an .ini file where one of the lines is for the output of a file. i need to substitute the current output in the file with a filepath that is stored in my vb app (named filepath). so i need a snippet that will open the ini file, find the correct line, and place my variable in there. ill paste in what the ini file looks like

its not code so i suppose i shouldn't place tags around it. so that first line needs to have my new filepath in it.
I have about 7,000 files (with temporary file names) that I need to replace with specific file names.
I figure I can match up the temp file names with the needed file names in
access. I'm not sure where to go from there.
I do not have to use a database if there is another way of going about it
but I do not think there is.
amounts of file names to unqiue IDs/names?

The issue I have, is if I try to use any sort of IO function after this (WriteAllLines, streamwriter, etc) - I get a process is being used and can't touch the file (because its being read).Must I somehow create a new file with a copy of everything including the replaced string?
I am using the following code, but cannot get this to work. I have got it to work if the replacement is just of one word. So if the word test is replaced by mouse and the only thing in the file is the word test, it works.
How can I replace like this:
CH_IPVOD_filename.mpg > replace the CH_IPVOD_ with nothing for the result of:
filename.mpg

View 2 RepliesIn my current program I need to be able to copy a text file, renaming it to default.txt, and overwriting the existing default.txt.
View 3 RepliesI've got two programs, one is the main and the other is the updater. So far iv'e got it so that the main program checks for an update by comparing its version number with the latest one that's stored as a text file on the server. If there's a newer one, the update program is started and the main one closed. The update program will then use a web browser component to navigate to the download link and download the new version. The only problem I'm having at the moment is, How can I get the new downloaded version to replace the current one in Program Files? and will this cause permission problems?
View 10 RepliesI created a setup project along with my main program everything compiles ok and I'm able to install a successfully. The problem I am experiencing is when I try to install over the previous version. I have set the setup property RemovePreviousVersion to TRUE , DetectNewerInstalledVersion to TRUE and I also increment the Version number and choose Yes when prompted to automatically change the ProductCode.
What I find is that when I install my program, the date on a subfolder changes, I don't expect the dates of the support files to change. but I do expect the date of my main .exe file to change. Unfortunately it stays the same. Running the program also shows that this file was not updated. I have read the MSDN articles on this but cannot figure it out.
I have a binary file. If I look at it with a hex editor, the first values are:208, 207, 17, 224, 161, 177, 26, 225, 0, 0, 0, ... etc.It has a length of 330240 bytes I have tried to open it and read it into a string so I can manipulate it and write it back. No matter what I use, I either don't get the correct number of bytes or the values in the string are incorrect. The most common error results in the first values being: 63, 63, 17, 63, 63, 26, 0, 0, 0 .... etc.It is interesting that it appears that any value > 63 becomes 63.
I get the 2nd values by a simple loop:
For lnx = 0 To 99
Debug.Write(Asc(line.Substring(lnx, 1)))
Next
I have tried a whole number of ways to read in the file, including filestream, My.Computer.FileSystem.ReadAllText, File.io.readAllLines, etc.All either give me a string length of about 324000 (not sure why) or, if they do, don't have the correct values. Yes, I have tried various encoding options.
I need to find a string (sort of like: "D" & Chr(0) + "L" & Chr(0) + "S" & Chr(0)... ) so I can then replace that portion of the string with a new value, then write out the file.I use the ".indexOf" to find the data in the string.Why can't I load the file into a string? Or, do you know of an easy way to find some text (similar to above) in a file and then replace the next x number of bytes with a new value and close the file?
I am trying to replace a string which is actually different from line to line in a text file. I want to end up with a filename but without the path. For example:

View 8 RepliesI have some large csv files (1.5gb each) where I need to replace specific values. The method I'm currently using is terribly slow and I'm fairly certain that there should be a way to speed this up but I'm just not experienced enough to know what I should be doing. This is my first post and I tried searching through to find something relevant but didn't come across anything.
My other thought would be to break the file into chunks so that I can read the entire thing into memory, do all of the replacements there and then output to a consolidated file. I tried this but the way I did it actually ended up seeming slower than my current method.
