Successful deployment does not guarantee successful running and performance of the code. It deployed code, which means your application is live. It doesn't run, it means it requires some tweaking.
Of course, this problem means that development machine and hosting machine are entirely (or somewhat) configured differently. So, check the settings in order to run the applicatio. In many cases, you are just hiding a feature from application, or there is a lock that prevents it to perform.

Does anyone know how to create a signature form in asp.net where a person signs in a blank space and then saves the signature and then it sends an email to another person to approve.
|
|

Yes, that is known as a canvas; where you can use mouse to draw over. You can support other input methods and devices too, if preferred. This is a basic HTML API that doesn't require only ASP.NET to work, but can work overall in web.

Note: Under any case, that "someone" will know what you are trying to ask for, and they might not sign.

Hy all,
i have:
<asp:Button ID="ButtonCheckIN" runat="server" Text="Edit" CommandArgument='<%# GetBLText(Bind("BL_MODULE").AsEnumerable(), "UN_ML_ID")%>' CommandName="CheckIn" />
When I run it, it throws error saying "'Bind' is not declared. It may be inaccessible due to its protection level". Can you help me?
|
|

|

Try Eval instead of Bind.

Hi, I have DataBind function in my code which binds to ListView. It doesnt work with Eval.
Examples:
works:
<%# Bind("BL_MODULE")%>
doesnt work:
<%# GetBLText(Bind("BL_MODULE").AsEnumerable(), "UN_ML_ID")%>
..and throws error
|
|
|
|
|
Bind is for read and write and eval is for read only. Since this is your button's CommandArgument read only is what you want.

I got it, but if do it using Eval:
<%# GetBLText(Eval("BL_MODULE"), "UN_ML_ID")%>
it throws run time error saying
does not contain a property with the name 'BL_MODULE'
|
|
|

I dont get why should I try FindControl and try to get my button. I dont need to get any buttons. I just need to solve one of the problems. One problem appears if I use Eval, the other- Bind. If I use Eval I get:
does not contain a property with the name 'BL_MODULE'
If I use Bind I get something like "Bind is not declared".
As I see, the offer I get here is to use Eval, so how to make program to think that there is a property. What datatype should I use to make property work. I tried DataTable as I thought that property should work as a column, but didnt work. String names checked. Its fine.

Yes, you are trying to set the CommandArgument property of the button in each and every Item in your ListView.
So, do it in C# instead of trying to get the right syntax in aspx. Simple and done.

The error is pretty clear - whatever you're binding to, it doesn't contain a property or field called BL_MODULE.
Using Bind won't change that. It will simply hide that error behind a different error.
Stick to using Eval, and either fix your property name, or fix your data source so that it contains the expected property.

How to change property name? Byt the way, I tried to change data source so that it contains expected property. I created DataTable and added column with such name, but the same error exists.
|

You either change the string you're passing to Eval so that it matches the name of a property / field on your data source, or you change the data source so that it contains a property with the specified name.
If you're still getting the "property not found" error, then you've done something wrong. Either the property name doesn't match, or you're not binding to what you think you're binding to.

normally these days many web site provide OAuth to login to their web api but how we can use the same oauth for web api ?
client will send user id and pwd in plain text to web api and web api will send those client credentials to oauth site ?
if user credentials found right then OAuth will send token to web api and web api will send token to client and from the next subsequent call web api will use the same token for each request...........am i right ?
if my thinking is wrong then just briefly tell me how oauth is used with web api and how client send their credentials and how get token etc. thanks

Same as your question on HMAC.
|
|
|
|
|
just was reading a article on web API with HMAC authentication from this url http://www.piotrwalat.net/hmac-authentication-in-asp-net-web-api/
if possible some one briefly discuss what is HMAC authentication and How this type of authentication works for web api ?
what i understood from their article that client will have a secret key and when client will request web api service then they will send hash of secret key along with request and web service will compare the hash and if match then it allow to call action ?
if i understood correctly then i have some question. suppose if am sending hash of a secret key to web api then how web api know what key client have ? because if web api has to generate hash of secret key what client used for comparing at service end then web api has to know which client is sending data.
there is change of Replay attack for HMAC authentication for web api
the article raise some points which is not clear to me to prevent the chance of Replay attack for HMAC authentication for web api.
the points are
Imagine a malicious third party intercepts a valid (properly authenticated) HTTP request coming from a legitimate client
(eg. using a sniffer). Such a message can be stored and resent to our server at any time enabling attacker to repeat operations
performed previously by authenticated users. Please note that new messages still cannot be created as the attacker does not
know the secret nor has a way of retrieving it from intercepted data.
1) requests with different Date header values will have different signatures, thus attacker will not be able to modify the timestamp
we will generate hash based on secret key then how date comes to scene ? this points is not clear to me.
2) we introduce a requirement that no http request can be older than X (eg. 5) minutes - if for any reason the message is
delayed for more than that it will have to be resent with a refreshed timestamp.
point two is not clear. what this area try to mean delayed for more than that it will have to be resent with a refreshed timestamp.

I wrote an application in asp net (3.5).
From an .aspx page should be interfaced a script in asp.
I meant that the aspx page after viewing waits X seconds and then using HTTPRequest and POST call the asp page.
In the aspx page I inserted a timer that delays the execution of the asp page X seconds.
When I use firefox working properly, while chrome is in the loop, that is the status bar see that continually draws the current page without stopping, ending only when I close the course page.
Searching the net I saw that chrome and safari have some incompatibility.
Where did I go wrong ?
What can be done to solve this problem, taking into account that I can not replace the ASP page with an .aspx, because it uses COM objects that do not know the features?
Someone enlighten me !!!

Good day
We have the requirement to invoke a Microsoft Outlook Meeting request from an Intranet web page without having the following (well known) message:
An ActiveX control on this page might be unsafe to interact with other parts of this page. Do you want to allow this interaction?
We want to use the standard installed (client side) Microsoft outlook libraries for that.
We do not want to relax the Local intranet Zone in IE by means of the standard resolution method of enabling the “Initialize and script ActiveX controls not marked as safe for scripting” Setting.
This is a simplified version of the code, the message is invoked by the highlighted portion
<body>
<form id="frmScheduleAMeeting" runat="server">
<div>
<input id="btnScheduleTheMeeting" type="button" value="Schedule the meeting" onclick="ScheduleTheMeeting()" style="width: 200px" />
</div>
</form>
<script type="text/javascript">
function ScheduleTheMeeting() {
var theApp;
var theMeeting;
var theApp = new ActiveXObject("Outlook.Application");
var objNS = theApp.GetNameSpace('MAPI');
var theMeeting = theApp.CreateItem(1);
theMeeting.Subject = "Will this time suit you?";
theMeeting.Location = "Your Office";
theMeeting.Recipients.Add("someone@microsoft.com");
theMeeting.Start = "01/01/2017 10:00:00"
theMeeting.End = "01/01/2017 11:00:00"
theMeeting.ReminderMinutesBeforeStart = 15;
theMeeting.BusyStatus = 1;
theMeeting.AllDayEvent = false;
theMeeting.BusyStatus = 1;
theMeeting.Save();
theMeeting.Display();
theMeeting.Recipients.ResolveAll();
theMeeting.Save();
}
</script>
</body>
We have tried to mark it safe in the registry as safe for scripting (7DD95801-9882-11CF-9FA9-00AA006C42C4) and safe for initializing from persistent data (7DD95802-9882-11CF-9FA9-00AA006C42C4).

An ActiveX control which is not marked as "safe for scripting" cannot be access from script unless you change the security settings.
If you did manage to change it so that it was marked as "safe for scripting", then any site on the internet could use it to wreak havoc on your users' email.
Try creating your own ActiveX control to perform the specific tasks you need, and locking it down to your intranet site:
Per-Site ActiveX Controls (Internet Explorer)[^]
Alternatively, see if you can do what you need with an iCalendar file, which would have the added advantage of working in other browsers and calendars too.

Hello, our company website is getting hit hard from malicious bots. I wish to propose a solution which involves changes to our web.config file. The trick is that I wish for the general search engine traffic to continue; I'm just interested in preventing the malicious bots.
This is an example of what I'm seeing online:
http://blog.arvixe.com/how-to-block-malicious-bots-and-spiders-in-web-config
The author seems to be restricting all search engines. Is this correct? If so, does anyone have an alternative that will allow for general search engine traffic to visit but restrict specific malicious bots? (I'd prefer to edit the web.config, since I don't believe that malicious bots care about the robots.txt file.)
Thanks!

I experimented with that years ago writing a program called bot catcher or something, the program is located in my profile in articles submitted.
Over the years, the bots just change their names over and over and it becomes a circular task that chews up so much time.
I guess to anwser your question, no I have not used the web config or knew that method existed. I'm just saying that manual operation of adding bots to that config is time consuming.
IMHO, the best solution is to just block an entire country using something like a Sonic Wall.
You can create automated programs that will detect and block by IP Address, but the bot activity will detect the block and notify it's master of it; then the master will put your website on a army of machines starting in Russia, then China and so forth. If you keep blocking those, then the army grows till it wraps around the world and it's 24/7.
So after 4 years of experimenting, I finally just broke down and bought a $2K Dell NSA 2600 Sonicwall and purchased a 3 year contract to filter out bad stuff; works like a champ now and they do all the work.
Now I can focus on just writing better more efficient code to keep user data safe.
