String csvPath = Path.Combine( Server.MapPath("~/Files/") +
Path.GetFileName(FileUpload1.PostedFile.FileName));
FileUpload1.SaveAs(csvPath);
DataTable dt = new DataTable();
dt.Columns.AddRange(
new DataColumn[3]{
new DataColumn("KPI", typeof(string)),
new DataColumn("KPIPN", typeof(string)),
new DataColumn("KPIPV", typeof(string))

We send emails via the Admin API, with PDF attachments the PDF is then unreadable, with TXT files there is no problem.
Doku: https://shopware.stoplight.io/docs/admin-api/743f0819350c4-send-a-mail
Request-URL: _action/mail-template/send
We use the binAttachments parameter set as follows.
The "content" is fetched and without BASE64 encoding the JSON code is corrupt, if you encode it the mail can be sent. But the attachment is not valid with/without encoding.
$content = file_get_contents()
$binAttachments[] = ["content" => base64_encode($content),
"fileName" => 'test.pdf',
"mimeType" => 'application/pdf'
];
No decode is done in the API controller, here is my suggestion for change?
Adjustment of the controller
\Shopware\Core\Content\MailTemplate\Api\MailActionController
public function send(RequestDataBag $post, Context $context): JsonResponse
direkt nach der Zeile
$data = $post->all();
/optionale Decodierung des Strings, falls es ein BASE64 ist/
foreach ($data['binAttachments'] as &$binAttachment) {
if (base64_decode($binAttachment['content'], true)) {
// is valid $binAttachment['content'] = base64_decode($binAttachment['content']);
} else {
// not valid, Nothing to do
}
}

I have create One API controller and i want to pass custom error class object as a response.
Can any one help me for that ?
Thanks in advance.
Create one class for to store error information as shown below.
ErrorInformation objError = new ErrorInformation();
try
{
test(ref Token, ref SessionToken);
}
catch (Exception ex)
{
objError.ErrorMessage = ex.Message;
objError.StatusCode = Convert.ToInt16(HttpStatusCode.ExpectationFailed);
objError.ErrorType = ex.GetType().ToString();
objError.ErrorCode = "E01";
throw new HttpResponseException(Request.CreateResponse<ErrorInformation>(HttpStatusCode.ExpectationFailed, objError));
}
This will return whole object as result.
{
"StatusCode": 417,
"ErrorMessage": "Error Detail",
"ErrorType": "System.DivideByZeroException",
"ErrorCode": "E01"
}

I Already done updating the password in database using SQLAdpaters in IBM Worklight Hybrid App.
I am Working on Hybrid App using IBM Worklight. I am updating user password in database using SQLAdapter, but I want to store password in encrypted format. I already have the encryption and decryption logic in java class. How can I integrate that java class with my hybrid app?
var procedure1Statement = WL.Server.createSQLStatement("UPDATE USERS SET USERPASSWORD=? WHERE USERNAME = ? AND USERPASSWORD=? ");
function updateUserPassword(newPassword,userName,password) {
return WL.Server.invokeSQLStatement({
preparedStatement : procedure1Statement,
parameters : [newPassword,userName,password]
});
}
changed code as follows
var userpwdUpdateStatement = WL.Server.createSQLStatement("UPDATE USERS SET USERPASSWORD=? WHERE USERNAME = ? AND USERPASSWORD=? ");
function updateUserPassword(newPassword,userName,password) {
var encryptdecryptutility = new com.abcd.bgf.SysCRAESencrpDecrp();
var encryptnewPassword = encryptdecryptutility.encrypt(newPassword);
var encryptoldPassword = encryptdecryptutility.encrypt(password);
return WL.Server.invokeSQLStatement({
preparedStatement : userpwdUpdateStatement,
parameters : [encryptnewPassword,userName,encryptoldPassword]
});
}

Is there a way to extract a zip file into the computer's memory at runtime (e.g. to extract a picture but put it temporarily in the memory and place it on a PictureBox)
LIBRARIES ARE ALLOWED.
I think this should work.(not tested)
Requires .net 4.5(System.IO.Compression.dll)
using System.IO.Compression;
...
byte [] pictureBuffer = null;
using (ZipArchive archive = ZipFile.OpenRead(zipPath))
{
foreach (var entry in archive.Entries)
{
if(entry.FullName == "SomePicture")
{
using (zipEntryStream = entry.Open())
using (MemoryStream memStream = new MemoryStream())
{
zipEntryStream.CopyTo(memStream);
pictureBuffer = zipEntryStream.ToArray;
}
}
}
I think this should work.(not tested)
using the DotNetZip Library http://www.nuget.org/packages/DotNetZip/
using (ZipFile zip = new ZipFile(zipPath))
{
foreach (var entry in zip.Entries)
{
if(entry.FileName == "SomePicture")
{
using (var zipEntryStream = entry.OpenReader())
using (var memStream = new MemoryStream())
{
zipEntryStream.CopyTo(memStream);
pictureBuffer = zipEntryStream.ToArray;
}
}
}
}

I need a free and quick to download program that can test a connection string.
You can make one yourself in 20sec. For example in C#
- Create a new WinForms application
- Create a new SqlConnection(connectionString)
- Exception => Bad connection string
- All ok => Good connection string
SqlConnection conn = null;
try {
conn = new SqlConnection("connection string here");
conn.Open();
// Good connection string
} catch (SqlException sqlE) {
// Bad connection string
} finally {
if (conn != null) conn.Dispose();
}
An abbreviated version of Xyphrax's answer (assuming you're running this in the debugger):
using(var conn = new SqlConnection("Connection String Here"))
conn.Open();
You can use a tinny Windows application tool: http://www.webpowersoftware.com/App/Tools/SqlServer/SqlServerConnectionTest.exe.
