How can I make this regex not accept spaces?: [0-9a-zA-Z' ']{3,}
Everything I'm reading says to put a * or a + after the [] , but I get an invalid expression error when I do. The end result I'm looking for is a string of letters and numbers only - no spaces inbetween.
I have an application where the user uploads files.
GOAL:
I need to check the file name for special characters and replace them with an underscore. Is there a Select Statement OR IF Statement I can use to search the fileName for unwanted special charaters; those characters will be replaced with a blank or underscore?
I want to replace ampersand, Number sign, Apostrophe, and so on.
I'm using the technic described in: [URL]
to allow users to download files. Our group uses a tool called SecureGateway which doesn't seem to like FTP as a protocol.
Smaller files don't seem to have a problem, but intermittently larger files (larger than 10K) will not download to the client properly. They will just abruptly end the transfer as if they are actually completed.
I use the following code:
{
System.IO.
Stream iStream =
null;// Buffer to read 10K bytes in chunk:
byte[] buffer =
new
Byte[10000];// Length of the file:
int length;// Total bytes to read:
// string filepath = "DownloadFileName";
long dataToRead;// Identify the file to download including its path.
String filepath = Request.Params["file"].ToString();//
Identify the file name.
string filename = System.IO.Path.GetFileName(filepath);
try
{
// Open the file.
iStream = new System.IO.FileStream(filepath, System.IO.FileMode.Open,FileAccess.Read,
System.IO.FileShare.Read);
// Total bytes to read:
dataToRead = iStream.Length;
Response.ContentType = Response.AddHeader("application/octet-stream";"Content-Disposition",
"attachment; filename="" + filename +
""");
// Read the bytes.
while (dataToRead > 0)
{ // Verify that the client is connected.
if (Response.IsClientConnected)// Read the data in buffer.
{
length = iStream.Read(buffer, 0, 10000);
// Write the data to the current output stream.
Response.OutputStream.Write(buffer, 0, length);
// Flush the data to the HTML output.
Response.Flush();
buffer = new
Byte[10000];
dataToRead = dataToRead - length;
}
else
{
//prevent infinite loop if user disconnects
dataToRead = -1;
}
}
}
{
catch (Exception ex)// Trap the error, if any.
{
Response.Write("Error : " + ex.Message);
}
finally
{
if (iStream !=
null)//Close the file.
iStream.Close();
}
}
}
I know that there is a preset size restriction that you have to override when uploading a file to the server, just wondering if someone knows of a similar issue with downloading to the client.
I have a fileupload in my ASP.net as well as other fields, of which some are mandatory.
If I populate the fileupload with a file and press save, because some of the mandatory fields are missing I stop the save and show an error message. However when the screen refreshes ansd shows the error message I loose the file in fileupload. Is there a way of retaining this?

I'm working on security of login page.
how can i restrict user to perform 'rules violating actions' like performing back button operation after logging in?
when a user logs in then unless that user presses logout button, it should not see login page again. if user presses back button after login then its current page should be reloaded.
if there are two consecutive apostrophe or two consecutive hyphens or two consecutive comma or two consecutive spaces or two consecutive periods or two consecutive periods..I want to display those particular error.
and One more thing is if there are any of the above combinations like apostrophe+hyphen or apostrophe+space or hyphen+space, I want to throw that specific error.
I'm having an issue in my ASP.NET web app where intentionally consecutive backslashes are being removed from the request url.
I'll request something like:
localhost/Page/A//C
But when the request hits the page, the raw url is:
localhost/Page/A/C
Not sure if this is the culprit, but I do have a Url Rewite regex in place, here's the rule:
<system.webServer>
<rewrite>
<rules>[code]...
So, after the rewrite, the querystring is coming out as Page.aspx?1=A&2=C&3= When it should be Page.aspx?1=A&2=&3=C
I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.

routes.MapRoute(
"categories",
"category/{categoryID}/{categoryName}",
new { controller = "Search", action = "SearchResults", categoryID = "", categoryName = "" }
