I'm trying to get the php sha1(md5($Password)); like this
public static string GetSha1MD5Pass(string value)
{
var data = System.Text.Encoding.ASCII.GetBytes(value);
var datamd5 = System.Security.Cryptography.MD5.Create().ComputeHash(data);
var data64 = Convert.ToBase64String(datamd5);
var data64e = Encoding.ASCII.GetBytes(data64);
var hashData = new SHA1Managed().ComputeHash(data64e);
var hash = string.Empty;
foreach (var b in hashData)
{
hash += b.ToString("X2");
}
return hash;
}
I call it like this :
command.Parameters.AddWithValue("#pwd", Crypto.GetSha1MD5Pass(password));
where Crypto its class I made were GetSha1MD5Pass resides
but it clearly failed, maybe someone here can help me, thank you
MD5 is not recommended for secure hashing. It's considered a deprecated algorithm because it is relatively easy to break. The current recommendation is to use PBKDF2-HMAC-SHA256 with 310,000 iterations.
You can achieve this relatively easy in ASP.NET Core using the PasswordHasher helper in the Microsoft.AspNetCore.Identity package. It has HashPassword and a VerifyHashedPassword methods. By default, the number of iterations is set to 10,000, but you can reconfigure that yourself:
builder.Services.Configure<PasswordHasherOptions>(options =>
{
options.IterationCount = 310000;
});
I have a working example of using the PasswordHasher here: https://github.com/mikebrind/Razor-Pages-In-Action/tree/main/Chapter13/PasswordHasherDemo
If you are migrating an old PHP app to .NET Core, now is the time to improve your security. Anyone who tries to log in using their old PHP password should be told that their password needs resetting, and then you can store the reset one using up-to-date APIs. Store it in a new column, perhaps, so you know whether someone had updated their password or not.
I'm developing an extension for Visual Studio that includes a XAML view inside a VS window. I want the extension to look and feel like the native UI. The extension is currently running and working fine in VS2017 and VS2019 using the following code to transform a moniker to a WPF BitmapSource that can be used directly from XAML:
public static BitmapSource GetIconForImageMoniker(ImageMoniker? imageMoniker, int sizeX, int sizeY)
{
if (imageMoniker == null)
{
return null;
}
IVsImageService2 vsIconService = ServiceProvider.GlobalProvider.GetService(typeof(SVsImageService)) as IVsImageService2;
if (vsIconService == null)
{
return null;
}
ImageAttributes imageAttributes = new ImageAttributes
{
Flags = (uint)_ImageAttributesFlags.IAF_RequiredFlags,
ImageType = (uint)_UIImageType.IT_Bitmap,
Format = (uint)_UIDataFormat.DF_WPF,
LogicalHeight = sizeY,
LogicalWidth = sizeX,
StructSize = Marshal.SizeOf(typeof(ImageAttributes))
};
IVsUIObject result = vsIconService.GetImage(imageMoniker.Value, imageAttributes);
object data;
result.get_Data(out data);
BitmapSource glyph = data as BitmapSource;
if (glyph != null)
{
glyph.Freeze();
}
return glyph;
}
This method is a direct copy-paste from the WpfUtil class available in multiple of Mads Kristensen's extensions.
As already mentioned, this works fine in VS2017 and VS2019. Now I want this running in VS2022 as well. The extension shows up inside VS2022 but the icons are no longer shown. The problem is that this returns null in VS2022 but not in the previous versions:
ServiceProvider.GlobalProvider.GetService(typeof(SVsImageService)) as IVsImageService2;
Does anyone know how to make this work in VS2022 as well?
This is caused by changes to the interop libraries in VS2022. Namely, they've all been consolidated to a single library (you can see the details here).
This does break compatibility with targeting prior versions of Visual Studio. There is a guide for migrating extensions to VS2022, but to summarize, the guidance is to:
Refactor the source code into a Shared Project.
Create a new VSIX projects targeting VS2022 and the VSIX project you have now would remain for targeting prior versions.
I have run into a road block developing my Codename One app. One of my classes in my project parses 3 specific html "td" elements from a website and saves the text to a string where I then input that text data into a Codename One multibutton. I originally used jSoup for this operation but soon realized that Codename One doesn't support 3rd party jar files so I used this method as shown below.
public void showOilPrice() {
if (current != null) {
current.show();
return;
}
WebBrowser b = new WebBrowser() {
#Override
public void onLoad(String url) {
BrowserComponent c = (BrowserComponent) this.getInternal();
JavascriptContext ctx = new JavascriptContext(c);
String wtiLast = (String) ctx.get("document.getElementById('pair_8849').childNodes[4].innerText");
String wtiPrev = (String) ctx.get("document.getElementById('pair_8849').childNodes[5].innerText");
String wtiChange = (String) ctx.get("document.getElementById('pair_8849').childNodes[8].innerText");
Form op = new Form("Oil Prices", new BoxLayout(BoxLayout.Y_AXIS));
MultiButton wti = new MultiButton("West Texas Intermediate");
Image icon = null;
Image emblem = null;
wti.setEmblem(emblem);
wti.setTextLine2("Current Price: " + wtiLast);
wti.setTextLine3("Previous: " + wtiPrev);
wti.setTextLine4("Change: " + wtiChange);
op.add(wti);
op.show();
}
};
b.setURL("https://sslcomrates.forexprostools.com/index.php?force_lang=1&pairs_ids=8833;8849;954867;8988;8861;8862;&header-text-color=%23FFFFFF&curr-name-color=%230059b0&inner-text-color=%23000000&green-text-color=%232A8215&green-background=%23B7F4C2&red-text-color=%23DC0001&red-background=%23FFE2E2&inner-border-color=%23CBCBCB&border-color=%23cbcbcb&bg1=%23F6F6F6&bg2=%23ffffff&open=show&last_update=show");
}
This method works in the simulator (and gives a "depreciated API" warning), but does not run when I submit my build online after signing. I have imported the parse4cn1 and cn1JSON libraries and have gone through a series of obstacles but I still receive a build error when I submit. I want to start fresh and use an alternative method if one exists. Is there a way that I can rewrite this segment of code without having to use these libraries? Maybe by using the XMLParser class?
The deprecation is for the WebBrowser class. You can use BrowserComponent directly so WebBrowser is redundant in this case.
I used XMLParser for this use case in the past. It should work with HTML as it was originally designed to show HTML.
It might also be possible to port JSoup to Codename One although I'm not sure about the scope of effort involved.
It's very possible that onLoad isn't invoked for a site you don't actually see rendered so the question is what specifically failed on the device?
We are looking to add Microsoft Reports - SSRS to one of our internal websites.
The database has all the reporting features installed.
The website is using Entity Framework 4 for all data.
I have been able to create a report using the old fashioned way of creating a DataSet (*.XSD) and this works well.
My question though, is it possible to utilise the existing Entity Framework in the site for the data required by the reports? Rather than having to re-invent the wheel and make a whole DataSet, along with relationships etc..
It's a website and not application, so this (http://weblogs.asp.net/rajbk/archive/2010/05/09/creating-an-asp-net-report-using-visual-studio-2010-part-1.aspx) doesn't seem to apply; I don't see the DataSource (in part 2 of the tutorial)
Update
As a side-note, we would like to steer clear of expensive third-party controls etc.
Also, another way to look at the issue might be to generate the *.XSD from the entity framework entity model; is this possible? It's not ideal though would get us up and running..
Below is a quick sample of how i set the report datasource in one of my .NET winForms applications.
public void getMyReportData()
{
using (myEntityDataModel v = new myEntityDataModel())
{
var reportQuery = (from r in v.myTable
select new
{
l.ID,
l.LeaveApplicationDate,
l.EmployeeNumber,
l.EmployeeName,
l.StartDate,
l.EndDate,
l.Supervisor,
l.Department,
l.Col1,
l.Col2,
.......,
.......,
l.Address
}).ToList();
reportViewer1.LocalReport.DataSources.Clear();
ReportDataSource datasource = new ReportDataSource("nameOfReportDataset", reportQuery);
reportViewer1.LocalReport.DataSources.Add(datasource);
Stream rpt = loadEmbededReportDefinition("Report1.rdlc");
reportViewer1.LocalReport.LoadReportDefinition(rpt);
reportViewer1.RefreshReport();
//Another way of setting the reportViewer report source
string exeFolder = Path.GetDirectoryName(Application.ExecutablePath);
string reportPath = Path.Combine(exeFolder, #"rdlcReports\Report1.rdlc");
reportViewer1.LocalReport.ReportPath = reportPath;
reportParameter p = new ReportParameter("DeptID", deptID.ToString());
reportViewer1.LocalReport.SetParameters(new[] { p });
}
}
public static Stream loadEmbededReportDefinition(string reportName)
{
Assembly _assembly = Assembly.GetExecutingAssembly();
Stream _reportStream = _assembly.GetManifestResourceStream("ProjectNamespace.rdlcReportsFolder." + reportName);
return _reportStream;
}
My approach has always been to use RDLC files with object data sources and run them in 'local' mode. These data sources are ... my entities! This way, I'm using all of the same business logic, string formatting, culture awareness, etc. that I use for my web apps. There are a some quirks, but I've been able to live with them:
RDLC files don't like to live in web projects. We create a separate dummy winform project and add the RDLC files there.
I don't show reports in a viewer. I let the user download a PDF, Word, or Excel file and choose to save or open in the native viewer. This saves a bunch of headaches, but can put some folks off, depending on requirements. For mobile devices, it's pretty nice.
Since you are not using SSRS, you don't get the nice subscription feature. You are going to build that, if required. In many ways, though, I prefer this.
However, the benefits are really nice:
I'm using all of the same business logic goodness that I've already written for my views.
I have a custom ReportActionResult and DownloadReport controller method that allows me to essentially run any report via a single URL. This can be VERY handy. It sure makes a custom subscription component easier.
Report development seems to go pretty quick, now that I only need to adjust entity partial classes to tweak a little something here or there. Also - If I need to shape the data just a bit differently, I have LINQ.
We too use SSRS as "local" reports. We create Views in SQL server, then create that Object in our application along with the other EF Domain Models, and query that object using our DbContext. We use an ASPX page and use the code behind (Page_Load) to get the data passed to the report.
Here is an example of how we query it in the Page_Load Event:
var person = MyDbContext
.Query<ReportModel>()
.Where(x => x.PersonId == personId)
.Where(x => x.Year == year)
.Select(x =>
{
PersonId = x.PersonId,
Year = x.Year,
Name = x.Name
});
var datasource = new ReportDataSource("DataSet1", person.ToList());
if (!Page.IsPostBack)
{
myReport.Visible = true;
myReport.ProcessingMode = ProcessingMode.Local;
myReport.LocalReport.ReportPath = #"Areas\Person\Reports\PersonReport.rdlc";
}
myReport.LocalReport.DataSources.Clear();
myReport.LocalReport.DataSources.Add(datasource);
myReport.LocalReport.Refresh();
The trick is to create a report (.rdlc) with a blank data source connection string, a blank query block and a blank DataSetInfo (I had to modify the xml manually). They must exist in file and be blank as follows:
SomeReport.rdlc (viewing as xml)
...
<DataSources>
<DataSource Name="conx">
<ConnectionProperties>
<DataProvider />
<ConnectString />
</ConnectionProperties>
<rd:DataSourceID>19f59849-cdff-4f18-8611-3c2d78c44269</rd:DataSourceID>
</DataSource>
</DataSources>
...
<Query>
<DataSourceName>conx</DataSourceName>
<CommandText />
<rd:UseGenericDesigner>true</rd:UseGenericDesigner>
</Query>
<rd:DataSetInfo>
<rd:DataSetName>SomeDataSetName</rd:DataSetName>
</rd:DataSetInfo>
now in a page event, I use a SelectedIndexChanged on a DropDownList, bind the report datasource as follows:
protected void theDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
if (theDropDownList.SelectedIndex == 0)
return;
var ds = DataTranslator.GetRosterReport(Int64.Parse(theDropDownList.SelectedValue));
_rvReport.LocalReport.ReportPath = "SomePathToThe\\Report.rdlc";
_rvReport.LocalReport.DataSources.Add(new ReportDataSource("SomeDataSetName", ds));
_rvReport.Visible = true;
_rvReport.LocalReport.Refresh();
}
You can use a WCF-Service as Datasource and so re-use your application data and logic for your report. This requires a SQL-server standard edition at least i believe. So no can do with the free SQL-express edition.
You can use LINQ with RDLC Report which is quite easy to use
LinqNewDataContext db = new LinqNewDataContext();
var query = from c in db.tbl_Temperatures
where c.Device_Id == "Tlog1"
select c;
var datasource = new ReportDataSource("DataSet1", query.ToList());
ReportViewer1.Visible = true;
ReportViewer1.ProcessingMode = ProcessingMode.Local;
ReportViewer1.LocalReport.ReportPath = #"Report6.rdlc";
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.DataSources.Add(datasource);
ReportViewer1.LocalReport.Refresh();
So this code runs in an asp.net app on Linux. The code calls one of my services. (WCF doesn't work on mono currently, that is why I'm using asmx). This code works AS INTENDED when running from Windows (while debugging). As soon as I deploy to Linux, it stops working. I'm definitely baffled. I've tested the service thoroughly and the service is fine.
Here is the code producing an error: (NewVisitor is a void function taking 3 strings in)
//This does not work.
try
{
var client = new Service1SoapClient();
var results = client.NewVisitor(Request.UserHostAddress, Request.UrlReferrer == null ? String.Empty : Request.UrlReferrer.ToString(), Request.UserAgent);
Logger.Debug("Result of client: " + results);
}
Here is the error generated: Object reference not set to an instance of an object
Here is the code that works perfectly:
//This works (from the service)
[WebMethod(CacheDuration = _cacheTime, Description = "Returns a List of Dates", MessageName = "GetDates")]
public List<MySqlDateTime> GetDates()
{
return db.GetDates();
}
//Here is the code for the method above
var client = new Service1Soap12Client();
var dbDates = client.GetDates();
I'd love to figure out why it is saying that the object is not set.
Methods tried:
new soap client.
new soap client with binding and endpoint address specified
Used channel factory to create and open the channel.
If more info is needed I can give more. I'm out of ideas.
It looks like a bug in mono. You should file a bug with a reproducible test case so it can be fixed (and possibly find a workaround you can use).
Unfortunately, I don't have Linux to test it but I'd suggest you put the client variable in an using() statement:
using(var client = new Service1SoapClient())
{
var results = client.NewVisitor(Request.UserHostAddress, Request.UrlReferrer == null ?
String.Empty : Request.UrlReferrer.ToString(), Request.UserAgent);
Logger.Debug("Result of client: " + results);
}
I hope it helps.
RC.
