Hi Naveed,

I came across the Server.MapPath too, so from what you say, the code should work when I upload it the server to be access by the public?

Regex.Matches() issue

Jes M George12-Apr-07 21:41

12-Apr-07 21:41

for finding matched pattern in strings i am using the function Regex.Matches().

the issue is that if i am passing a "pattern" string which have bracket"( )" then it will not return any matches..

for eg:

string strInput = "PaperIndex (India) Private Limited";

string strPattern = "PaperIndex (India) Private";

and if i am passing this value to function it will not return any match.

foreach (Match Mth in Regex.Matches(strInput , strPattern, RegexOptions.IgnoreCase))
{
arrBuyleadName.Add(Mth.Value);
}

if we pass strPattern = "PaperIndex";

it is returning the match value as paperindex

if any body know how to avoid this issue, help me

thanking you,

Jes.

For me the immediate work around is to replace the ( with something else and try to make a patter with that !!! And then use the Regex.Matches()!!!

You need to use the escape character '\'. For example: "PaperIndex \(India\) Private".

Typically it depends on the methods exposed by the camera software !! If there are methods exposed then you can very well use the drivers and access the images from camera if not then find out from provider itself

My feeling is the provider needs to be asked, as it is some times proprietary information !!!

Hi,
AFAIK, there is no OnFocus event in the ASP.NET textbox. If txt2 is the editable one, and you want to have txt3 updated when txt2 is changed, you could do:

Protected Sub txt2_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles txt2.TextChanged
     If Txt1 <> "" And Txt2 <> "" Then
          Txt3.Text = txt1.Text & txt2.Text
     Else
          'Error handling code
     End If
End Sub

Downloading a cab file without any chenge in content or size..

Hi,

I have a web application(ASP.net, C#) in which the user is be able to download a .cab file to the PC by clicking on a button after making a file selection. I tried many methods for accomplishing the download task.

The code i tried is given below.

Response.ContentType = "APPLICATION/OCTET-STREAM";
System.String disHeader = "Download; Filename=\"" + myfilename+ "\"";
Response.AppendHeader("Content-Disposition", disHeader);
System.IO.FileInfo fileToDownload = new System.IO.FileInfo(myfilepath);
Response.Flush();
Response.WriteFile(fileToDownload.FullName);

or

FileStream MyFileStream = new FileStream(myfilepath, FileMode.Open);
long FileSize;
FileSize = MyFileStream.Length;
byte[] Buffer = new byte[(int)FileSize];
MyFileStream.Read(Buffer, 0, (int)MyFileStream.Length);
MyFileStream.Close();
Response.ContentType = "application/octet-stream";
Response.AddHeader("content-disposition", "attachment; filename=" + myfilename);
Response.BinaryWrite(Buffer);

When i tried these two methods, i could download the files to the PC. The user has to copy the cab file to the Pocket PC device for installing it. The file downloaded through the web application may have some problem so that it cannot be installed on the Pocket PC.

When i tried to install the original file from the repository, it worked fine. It means that there occurs some problem with the cab file while it is being downloaded.

The original file is having the size 420 KB. But the file downloaded is having size 432 KB.

Could anybody guide me to solve the problem?

Thanks in advance.

Hi,
I don't know if you've tried this, but you could try:

public void SendFile(String myFilePath) {
     Response.TransmitFile(myFilePath)
}

For more information on Response.TransmitFile then go to:
