Working on a WPF app that hit's a Web API.On the server, I have this code in my BizObject:
public UserEntity Login(CredentialsEntity credentials)
{
var user = _repository.GetUser(credentials.UserName);
if (user != null)
{
if (Cryptology.CompareHashedString(user.Password, credentials.Password))
{
if (user.CanLogIn.HasValue && user.CanLogIn.Value)
{
return user;
}
}
}
return null;
}
While it works, the Password on the Credential object (credentials.Password) is in plain text. I know this isn't right, but I'm not sure of the correct way to do this?
What's the right way here?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

Make sure the web API is only available over HTTPS. That way, the transport takes care of encrypting the data in-flight for you.

I had a problem which I cannot solve for weeks and could not found any solution for it even I tried to look at NLayers but still not sure on how to do it. Can I ask that how can I read MPG Video into Naudio and control the left right channel? My customer does not want to change the video format to MP4, insist on using MPG file format for their KTV System.
Below is my snippet of codes
Im using Object as Player
<object id="Player" width="50" height="50" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" VIEWASTEXT>
<param name="SendPlayStateChangeEvents" value="true" />
<param name="autostart" value="true" />
<param name="URL" value="<%=mySrc %>"/>
<param name="enabled" value="True"/>
<param name="balance" value="0"/>
<%--<param name="currentPosition" value="<%=myFForRewind %>"/>--%>
<param name="enableContextMenu" value="True"/>
<param name="fullScreen" value="true"/>
<param name="mute" value="False"/>
<param name="playCount" value="1"/>
<param name="rate" value="1"/>
<param name="stretchToFit" value="false"/>
<param name="uiMode" value="none"/>
<param name="volume" value="<%=myVolume %>"/>
<!--[if !IE]>-->
<!--<![endif]-->
</object>
The Naudio Code as below:
protected void ImageButton7_Click(object sender, ImageClickEventArgs e)
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "StartMeUp()", true);
player.player1 = new DirectSoundOut();
player.player1.Init(player.mono);
player.player1.Play();
}

Naudio says it handles "audio" files and makes no mention of "video" files.

Did you check the MPEG file to make sure it's has a stereo audio track, and not a mono audio track?
You could use an MPEG inspector that will give you the details of the file.
Member 13943087 wrote: player.player1.Init(player.mono);
Your code say to play mono, which will combine both tracks, or default to the left or right audio channel.
Mono is a single audio track,
Stereo is a left and right audio track.
Dolby is a 5 channel audio track.
Guess us old guys remember the mono days, and AM radio, FM was broadcasted in stereo.

Hi all,
i draw a string diagonal on my Panel,
and draw this text with opacity option
get color for text like below:
PrintPageEventArgs pe;
int X = 0;
int Y = 0;
RectangleF rect2 = panel2.ClientRectangle;
float image_draw_wd = panel2.Width;
float image_draw_ht = panel2.Height;
Brush myBrush = new SolidBrush(Color.FromArgb(128, Color.Blue));
StringFormat stringFormat = new StringFormat();
stringFormat.Alignment = StringAlignment.Center;
stringFormat.FormatFlags = StringFormatFlags.LineLimit;
stringFormat.Trimming = StringTrimming.Word;
SizeF sz = pe.MeasureString(panel2.watermarkText, panel2.watermarkFont, (int)image_draw_wd, stringFormat);
double angle = 0;
double angleRadians = Math.Atan2(image_draw_ht, image_draw_wd);
angle = angleRadians * 180.0 / Math.PI;
pe.TranslateTransform((rect2.Location.X + rect2.Width / 2), (rect2.Location.Y + rect2.Height / 2));
pe.RotateTransform((float)angle + flip180Image);
pe.TranslateTransform(-(rect2.Location.X + rect2.Width / 2), -(rect2.Location.Y + rect2.Height / 2));
X = (int)(panel2.Width - sz.Width) / 2;
Y = (int)(panel2.Height - sz.Height) / 2;
RectangleF dr_rect = new RectangleF(new Point(X, Y, new Size(image_draw_wd , ((int)sz.Height) + extra_margin));
pe.DrawString(panel2.watermarkText, panel2.watermarkFont, myBrush, dr_rect, stringFormat);
but when i print it, the text not fully visible
if i draw it horizontally its working fine.
i cant understand where is the problem
please help me for this.
thanks alot

Quote: when i print it, the text not fully visible

This doesn't make any sense to us without the code you used to cause the problem: try generating a tiny bit of code that shows it working and not working, and post that for us so we can see exactly what you are doing. It you can explain what you mean by "not fully visible" that would help as well - does the left side work, but not the right, or the top but not the bottom, or every second character is gone, or what? We don't know, and it's probably relevant.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

That should crash: pe is null
PrintPageEventArgs pe;
...
SizeF sz = pe.MeasureString(panel2.watermarkText, panel2.watermarkFont, (int)image_draw_wd, stringFormat); You need to use the PrintPageEventArgs that is passed in as part of the PrintPage event or the metrics you use for MeasureString won't work anyway as they aren't relevant to the device context you are drawing on - even if you construct one somewhere and don't show it here.

its not null its come from here
private void PrintDocument1_PrintPage(object sender, PrintPageEventArgs pe)

Thanks - I assumed it would, but when it's explicitly shown as a new declaration it needs to be confirmed.

When you say "the text not fully visible" what exactly do you mean?

is there any option to show the image how can i upload my drawing image to describe u better
|

No, because we get some idiots here who would post ... ummm ... objectional material 
You wouldn't believe what tries to get through moderation ATM, and we can't moderate every post, there aren't enough of us volunteers to do that. And you don't have sufficient rep yet to store images here.
You could put it up on Dropbox / Google and provide a link?

OK - I'm trying to duplicate exactly what you have, but ... your code won't compile without errors and I don't want to fix them in case I "fix them wrong".
For example:
RectangleF dr_rect = new RectangleF(new Point(X, Y, new Size(image_draw_wd, ((int)sz.Height) + extra_margin));
Missing a close bracket (at a guess, after the "Point(X, Y" is where it goes).
PrintPageEventArgs doesn't contain methods MeasureString, TranslateTransform, and RotateTransform: PrintPageEventAgrs.Graphics does.
If that is copy'n'pasted from your app, then it's possible you are testing an older version of your source - in which case the display fault may no longer exist if you fix that code.

i already mention in preview its ok

Yes, but your code doesn't compile, so that has to be taken with a pinch of salt!

And if I change my code:
private void FrmMain_Shown(object sender, EventArgs e)
{
PrintDocument pd = new PrintDocument();
pd.PrintPage += Pd_PrintPage;
PrintDialog pdi = new PrintDialog { Document = pd };
pdi.ShowDialog();
pd.Print();
It prints fine to PDF, XPS, OneNote, ...
So the code seems OK as far as I can see.
So ... what happens if you fix the compiler errors, and print to - say - OneNote?

At a guess, driver problems.
I can't test that - I have a Samsung colour laser as I got fed up with inkjets never working when I needed them ...
