I have an intranet site to manage clients' communications. There are only a few controls: a textbox for the Subject, Attachment (fileUpload control), and a multiline textbox for the content of the email.
Using the fileUpload control, I select the pdf file that I want to send to clients. All the details about the clients (name, email address, etc) is coming from a sql table.
The sending works just fine, it sends the email with the attachment. However, the PDF attachment cannot be opened. The error is that the file hasn't been correctly decoded. I am not sure where the problem is. Does anyone have an idea on where the problem is?
Here is the code (for the sending procedure):
protected void BtnSendAcctClientsEmail_Click(object sender, EventArgs e)
{
if (uplAcctngAttachment.HasFile)
{
HttpPostedFile uploadedFile = uplAcctngAttachment.PostedFile;
if (IsAcctngFileHeaderValid(uploadedFile))
{
var fileName = Path.GetFileName(uplAcctngAttachment.PostedFile.FileName);
string strExtension = Path.GetExtension(fileName);
if (strExtension != ".pdf")
{
lblAcctngFileErr.Text = "Please attach pdf files only.";
return;
}

lblAcctngFileErr.Text = "";

When you pass the stream to the Attachment constructor it's offset by 2 bytes because you read from it earlier in IsAcctngFileHeaderValid corrupting the data.
Reset the stream position using uplAcctngAttachment.PostedFile.InputStream.Position = 0; when IsAcctngFileHeaderValid is done reading.

I know that i'm stuck in a silly problem...and now i am here with hope, that you can help me. Simple situation: I need to send email with attachment from database. I have done it by myself, but...i don't know why, but attachment in email what was send is incorrect. Preciously attachment contents code, what i get from my database.
My code:
static void IncomeMessage()
{
SqlConnection conn = new SqlConnection("Data Source=xxx;Initial Catalog=xxx;User ID=xxx;Password=xxx");
SqlCommand cmd = new SqlCommand("Here is my SQL SELECT", conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
try
{
var AID = dr["ID"].ToString();
var Ids = dr["MessageID"].ToString();
var SuperOrganizationTitle = dr["SuperOrganizationTitle"].ToString();
var Date = dr["Date"].ToString();
var Title = dr["Title"].ToString();
var Description = dr["Description"].ToString();
var DBFile = dr["File"].ToString();
var Filename = dr["FileName"].ToString();
MailMessage oMail = new MailMessage("test#test.com", "guntisvindels#gmail.com", "New message with theme: " + Title, "Message Income: " + Date + " From " + SuperOrganizationTitle + ". Message Content: " + Description);
DBFile = GetBase64(DBFile);
var bytes = Encoding.ASCII.GetBytes(DBFile);
MemoryStream strm = new MemoryStream(bytes);
Attachment data = new Attachment(strm, Filename);
ContentDisposition disposition = data.ContentDisposition;
data.ContentId = Filename;
data.ContentDisposition.Inline = true;
oMail.Attachments.Add(data);
SmtpClient oSmtp = new SmtpClient();
SmtpClient oServer = new SmtpClient("test.test.com");
oServer.Send(oMail);
}
catch (Exception ex)
{
//TraceAdd("Error=" + ex.Message.ToString());
}
}
}
For removing unnessessary data ( tags) from database File field i use this code
public static string GetBase64(string str)
{
var index1 = str.IndexOf("<content>");
index1 = index1 + "<content>".Length;
var index2 = str.IndexOf("</content>");
var kek = Slice(str, index1, index2);
return kek;
}
public static string Slice(string source, int start, int end)
{
if (end < 0)
{
end = source.Length + end;
}
int len = end - start;
return source.Substring(start, len);
}
When launching my code I can send email to me, and I'll recieve it. But message content attachment with my Base64 code from database File field. Here is a question - Where I got wrong, and how can I recieve email with correct attachment that has been written into database. Thank you for your attention
P.S Attachment in database is written correctly, because K2 integration platform can correctly display it
Here is example what database contain in File column (DBFile)
<file><name>zinojums.html</name><content>PGh0bWw+PGhlYWQ+PG1ldGEgaHR0cC1lcXVpdj0iQ29udGVudC1UeXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9dXRmLTgiIC8+PHN0eWxlPmh0bWwsYm9keXtmb250LWZhbWlseTpBcmlhbCxIZWx2ZXRpY2Esc2Fucy1zZXJpZjtmb250LXNpemU6MTBwdDt9aDF7Zm9udC1zaXplOjE0cHQ7fWgye2ZvbnQtc2l6ZToxMnB0O31we2JhY2tncm91bmQtY29sb3I6I0Y3RUVEQTttYXJnaW46MDtwYWRkaW5nOjhweDt9aHJ7aGVpZ2h0OjFweDsgYm9yZGVyOjAgbm9uZTsgY29sb3I6ICM1RjlCRDQ7IGJhY2tncm91bmQtY29sb3I6ICM1RjlCRDQ7fTwvc3R5bGU+PC9oZWFkPjxib2R5PjxoMT5JbmZvcm3EgWNpamEgbm8gVmFsc3RzIGllxYbEk211bXUgZGllbmVzdGE8L2gxPjxoMj5Eb2t1bWVudHMgcGllxYZlbXRzPC9oMj48cD5Ob2Rva8S8dSBtYWtzxIF0xIFqYSBOci4gPGI+TEFUVklKQVMgVkFMU1RTIFJBRElPIFVOIFRFTEVWxKpaSUpBUyBDRU5UUlMgQVMgKDQwMDAzMDExMjAzKTwvYj4gaWVzbmllZ3RhaXMgZG9rdW1lbnRzICI8Yj5aacWGYXMgcGFyIGRhcmJhIMWGxJNtxJNqaWVtPC9iPiIgTnIuIDxiPjU1NDYyNTY5PC9iPiBwaWXFhmVtdHMgdW4gaWVrxLxhdXRzIFZJRCBkYXR1YsSBesSTLjxiciAvPjwvcD48IS0tY29udGVudC0tPjxociAvPsWgaXMgZS1wYXN0cyBpciBpenZlaWRvdHMgYXV0b23EgXRpc2tpLCBsxatkemFtIHV6IHRvIG5lYXRiaWxkxJN0LjxiciAvPlBpZXNsxJNndGllcyBWSUQgRWxla3Ryb25pc2vEgXMgZGVrbGFyxJPFoWFuYXMgc2lzdMSTbWFpOiA8YSBocmVmPSJodHRwczovL2Vkcy52aWQuZ292Lmx2Ij5lZHMudmlkLmdvdi5sdjwvYT4uPC9ib2R5PjwvaHRtbD4=</content></file>
Right now the method you're using to create binary data from your string takes no account of the fact the string is base64-encoded specifically.
You need to replace
var bytes = Encoding.ASCII.GetBytes(DBFile);
with
var bytes = Convert.FromBase64String(DBFile);
I have windows service which periodically fetches data from table and creates excel file and mails it to users.After mail sending I need to delete that file. Have used following code:
public void LABInstrumentExcelGeneration(string filePath) {
try {
string connectionString = GetConnectionString(filePath);
List < LABInstruments > listLABInstrument = null;
listLABInstrument = new List < LABInstruments > ();
listLABInstrument = LABInstrumentBL.GetLABInstrumentList();
if (listLABInstrument.Count > 0) {
using(OleDbConnection conn = new OleDbConnection(connectionString)) {
conn.Open();
OleDbCommand cmd = new OleDbCommand();
cmd.Connection = conn;
cmd.CommandText = "CREATE TABLE [table2] (SrNo string,CalibrationDoneOn Date);";
cmd.ExecuteNonQuery();
foreach(LABInstruments tc1 in listLABInstrument) {
cmd.CommandText = "INSERT INTO [table2](SrNo,CalibrationDoneOn) VALUES('" + tc1.SrNo + "','" + tc1.CalibrationDoneOn + "');";
cmd.ExecuteNonQuery();
}
conn.Close();
conn.Dispose();
}
}
} catch (Exception ex) {}
}
SendMail(filePath, role);
if (File.Exists(filePath)) {
File.Delete(filePath);
eLog.WriteEntry("file deleted");
}
But it gives error File is being used by another process.
Ho can I delete file? Moreover, i've used OLEDB for file creation. Is there any other best practise for file creation? Have tried ExcelLibrary, but files created in it does not work in all versions of office so have dropped it.
Try this:
protected virtual bool IsLocked(FileInfo fileName)
{
FileStream fStream = null;
try
{
fStream = fileName.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
}
catch (IOException)
{
return true;
}
finally
{
if (fStream != null)
{
fStream.Close();
}
}
return false;
}
And then:
if (File.Exists(filePath))
{
FileInfo myfile = new FileInfo(filePath);
if(IsLocked(myfile))
{
File.Create(filePath).Close();
File.Delete(filePath);
eLog.WriteEntry("file deleted");
}
else
{
File.Delete(filePath);
eLog.WriteEntry("file deleted");
}
}
I think the problem may be that sendmail returns before it has finished using the file.
Instead of sendmail() I used this function which frees up the file for deletion:
public static void send(string subject, string body, string from, string to, List<string> attachments = null)
{
using (MailMessage message = new MailMessage(new MailAddress(from), new MailAddress(to)))
{
message.Subject = subject;
message.Body = body;
if (attachments != null && attachments.Count > 0)
{
foreach (string s in attachments)
{
if (s != null)
{
/* this code fixes the error where the attached file is
* prepended with the path of the file */
Attachment attachment = new Attachment(s, MediaTypeNames.Application.Octet);
ContentDisposition disposition = attachment.ContentDisposition;
disposition.CreationDate = File.GetCreationTime(s);
disposition.ModificationDate = File.GetLastWriteTime(s);
disposition.ReadDate = File.GetLastAccessTime(s);
disposition.FileName = Path.GetFileName(s);
disposition.Size = new FileInfo(s).Length;
disposition.DispositionType = DispositionTypeNames.Attachment;
message.Attachments.Add(attachment);
}
}
}
using (SmtpClient client = new SmtpClient())
{
client.Send(message);
}
}
}

You are getting the multiple users form the database that have birthdays with DataReader in a while loop. You just need to move the email sending code inside the loop.
I would recommend you to extract population report (name, birthday, hiredate, email) as excel and let wishing application take care of everything
At minimal it just need two things excel file with wish details (Date, name, email) and a configuration file (application.properties) and that is it, you are good to go.
Further there various options to run the application locally (Command line, foreground, background, docker, windows scheduler, unix cron etc) Cloud.
Application is highly configurable , you can configure various details like:
Workbook loading options
Image options to send with wishes.
SMTP Configurations
Other application level configurations like, when to send wish, belated wish, logging etc.

You did not make a proper .doc file. A .doc file is not composed of HTML. Word on your computer does know HTML so it will open the file, but likely the program you're using on the mobile devices will just treat it as a corrupted .doc file.
Instead, you should build a proper Word document. There's plenty of libraries for generating .docx Open Office XML Document (Word 2007) files. Find one that works for you needs, and use it.
Write the file on the server path and pass the link to user make the download:
Example:
http://yourapp.com/files/download/051651203210.doc
i am using asp.net and c#.net to send the mail with large attachments(max 10mb), that the reason i can convert the files, .txt,.doc,.xls file are perfectly sending but images and rar file corrupted what is the problem please give me any suggestion ,
My code is

}
at.TransferEncoding = System.Net.Mime.TransferEncoding.SevenBit;
// at.TransferEncoding = System.Net.Mime.TransferEncoding.QuotedPrintable;
message.Attachments.Add(at);
}
}
}
smtp.Timeout = 9999999;
smtp.Send(message);
web.config my code is
<httpRuntime executionTimeout="240" maxRequestLength="20480"/>
at.TransferEncoding = System.Net.Mime.TransferEncoding.SevenBit; i can give the comment in that line doesnot send the large files but all are perfectly working but i have send the large files maximum 10mb , pls give me suggestion
Unless there is some black magic taking place behind the scenes, I think you need to swap out fluuploader.FileContent with hpf.InputStream. Also, I find it helps to set the Position of the InputStream to 0. Your final code inside the for loop should look something like this:
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
hpf.InputStream.Position = 0;
if (i == 0)
{
string[] ext = System.IO.Path.GetFileName(hpf.FileName).Split('.');
attachId = filename + "." + ext[1];
at = new System.Net.Mail.Attachment(hpf.InputStream, attachId);
}
else
{
string[] ext = System.IO.Path.GetFileName(hpf.FileName).Split('.');
attachId = filename + "(" + i + ")" + "." + ext[1];
at = new System.Net.Mail.Attachment(hpf.InputStream, attachId);
}
message.Attachments.Add(at);
}
