Is there an easy way to disable all form validation when the user clicks on the "X" icon to close an application or when the user clicks on a button in the application that closes the application?[url]...
View 1 RepliesI have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.
This is the code I have so far.
Session("RequestID") = Server.HtmlEncode(txtRequestID.Value)
Session("FirstName") = Server.HtmlEncode(txtInstFirstName.Text)
Session("LastName") = Server.HtmlEncode(txtInstLastName.Text)

What can I do to make this work? According to all the websites I have visited it should work.
I have a textbox which I need to enter html code into (like < strong> or < em> for example). The trouble is this is causing an error writing this back to the database. A potentially dangerous Request.Form value was detected from the client (tbVOther="< strong>test.Is there a way around this without turning off the request validation setting?
View 3 RepliesMy asp.net page has multiple text-boxes and DropDownLists that all have required-field validators.
My site also has multiple pages that you can move between with the click of a button. (All pages have all the buttons) When a page loads and decide I want to go to a different page without entering information into the form, I click a button to move to a separate page and the validation pops up and I can't change the page, it stops me every time?
is it possible to disable validation of all items inside a panel programatically in vb.net?
i can't seem to figure it out.
i disabled all fields inside a panel, but they still cause the page to validate on submit.
this is what i have now:

View 1 RepliesI am installing an app I built in VB, and am getting the error "Application validation did not succeed. Unable to continue." I have successfully built and installed this app previously. What I think caused the issue is I attached the .mdf file I have referenced in my application to my SQL Server. I then detached the database in SQL Server, opened my VB app and re-built the app. When I tried to install the app, I received the error. Attached are the details of the error message.

I have a Data Acquisition and Control application that controls at 10 Hz and logs at 1 Hz. Both of those timers call a separate. I recently added a feature to the program to request 6 characters from a server for the barometric pressure. (29.206, etc) It works for the most part, but two weeks ago a computer froze, last week another one froze, and two froze this morning. I have not had freezing problems in the nearly three years this program has been running 24/7. Turns out they disconnected the server this morning, so that explains the simultaneous freezes in two test cells. I used a try catch statement, but apparently that wasn't good enough. how I can make this code more robust?

View 18 RepliesI am using System.IO.Ports.SerialPort in my project. This is the first time I am using this component.
Let me explain the issue. My desktop is connected to a weigh scale where I am taking the readings through the COM port. In a particular function I need to give new settings (Baud, Parity, StopBits, DataBits) to the serialport. So I am closing the existing object, and opening it again with new settings.
I am getting "The I/O operation has been aborted because of either a thread exit or an application request." exception while closing the serial port. The code is follows
If frmMDI.SerialPortReader.IsOpen Then
frmMDI.SerialPortReader.Close() //Exception comes here
End If
How can one pass http get or post methods to a windows application? I require a webserver to send a get method to my windows form application that will querry a database then reply back to a webserverI'm developing a windows based search engine that searches a MySQL database. It receives a keyword from an SMS gateway software as a HTTP get request and should reply to the gateway software using the same HTTP request.This is my code. It is correctly searching the database but I don't know how to receive the get methods on the application however it's sending the messages to SMS gateway.

I have a form in VS2010, written in VB, and it has a subroutine calling for information out on the web using an httpwebrequest object. It takes a while for the response, and I would like the subroutine to write a message to the form (into a Label) for the user to see while waiting for the application to respond.
I tried writing the message with a Backgroundworker and then as a second thread. I got it to write the message, but it always seems to wait for the http response before writing the text. How do I write the text immediately, while waiting for the data?
I am very confused about the database type to be used in my vb.net application. I have been using SSCE database, but for that user has to download and install SSCE, which many of my users do not want. If I use Access, the security issue is very very serious.I have downloaded a few database apps from the internet, which donot require any such thing to be installed and also I see no known database format in the application folder. I wonder what kind of techniques they are using.

When using WCF together with Enterprise Library 5.0's validation application block, is it possible to customize the error messages which are sent back to the client? I've added the ValidationBehaviour-attribute to my service contract and the FaultContract-attribute to the operation:

The service returns ValidationFault as it should, but instead of having the error message and tag which I've defined, it uses some generic values. Is this a bug or am I doing something wrong?
I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
I have a solution with two projects. The main project connects to the second project via a reference, and the reference path is local to my machine. It looks like it references the .exe file.So when I publish the main project (ClickOnce), i get the following error:
Application validation did not succeed. Unable to continue.In the log file, under Error Details, it says
System.Deployment.Application.InvalidDeploymentException (RefDefValidation)
- Reference in the manifest does not match the identity of the download assembly Project2.exe
- Source: System.Deployment
How can I include this second project? Should I publish it, then reference the published files? What do i reference? The .application file?Is there a way to just include this second project, so when I do publish the main project, the second one just goes along with it?

View 1 RepliesI've got a really good idea for an application I want to develop and possibly try and sell online. There is one thing I have never done before, and that is disabling an application after 30 days. Let's say I want to let users try out the application for 30 days, and if they haven't bought it after that time, then the application disables itself.
Any possible ideas on how to implement something like this?

View 4 RepliesEver since upgrading to Visual Studio 2010, I'm running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds before completing. Subsequent calls work quickly. I've narrowed down the problem to a proxy issue.If I manually disable proxy settings, I don't experience this delay:
Dim wrq As WebRequest = WebRequest.Create(Url)
wrq.Proxy = Nothing
What's strange is that there are no proxy settings enabled on this machine in Internet Options. What I'm wondering is if there is a way to disable proxy settings for my entire project in one shot without explicitly disabling as above for every web object.
The main reason I want to be able to do this is that I'm trying to use an API [URL] which uses web requests, but does not provide any way to manually disable proxy settings.I have found some information suggesting that I need to add some proxy information to the app.config file, but I get errors building my program if I make an edits to that file.

I am confused what will happen, when I disable a timer. Will it finish the process and then disable or will it immediately disable without completing process? for example

I want to run getMessage from somewhere else, so I need to disable timer during that time to be asured not to override anything and also before timer disable it should complete that function code.
