Error while using OpenFileDialog(). <>

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :.NET Framework



I am having an aspx page from which, on a button click an open file dialog should open up from which i can select a file.

i wrote the following code on the button's click event.

OpenFileDialog _filedialog = new OpenFileDialog();

            _filedialog.InitialDirectory = @"C:\";
            _filedialog.Title = "Add Preview Image";
            _filedialog.Filter = "Image files|*.jpeg;*.jpg;*.bmp;*.png";
            _filedialog.RestoreDirectory = true;
            if (_filedialog.ShowDialog() == DialogResult.OK)
                txtPromoPreviewImagePath.Text = _filedialog.FileName;


Now, when i run the project and click the button, hoping to see the open dialog file browser window, i see this following error.

Current thread must be set to sin

Sudden Error: Could not load type System.ServiceModel.Activation.HttpModule - Urgent Help Please


I have a windows 7 machine with IIS 7. I was hosting WCF services on IIS normally and i had a couple of services running.
Suddenly (i honestly did not do any configuration changes on my machine) all these services stopped working. When i try to browse the .svc file i get the following error:

"Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'"

Just in case this information is helpful, all these services are running on the basicHttpBinding.

Please help!

urgent: datalist validation error


hi guys,

i'm having error for my validation control... i'm using both the validation control and my own code for the validation of the input entered to the same textbox.  i added another validation code at the code behind and it seems that my validation control now doesnt work. it can check if the user does not enter any value or enter a non-integer value but then it will automatically go to my validation code at the code behind.

the error that i get is this "Conversion from string "" to type 'Double' is not valid." when i tried changing the string to type double, it said that "input string was not in a correct format"

below are my validation code

    Public Sub addToCart_cmd(ByVal sender As Object, ByVal e As DataListCommandEventArgs)
        If CType(e.CommandSource, Button).CommandName = "add" Then
            lblError.Text = ""

            Dim selectedSessionID As String = (CType(e.Item.FindControl("lblSessionID"), Label)).Text
            Dim selectedDate As String = (CType(e.Item.FindControl("lblDates"), Label)).Text
            Dim availablePax As String = (CType(e.Item.FindControl("lblAvailability"), Label)).Text

WCF de serialization error -- finding the erring field (urgent)


Hi Folks,

Need some urgent help. I am writing a WCF client which calls a service. Now, while de serializing the response from the service, the WCF client errs out with 'De serialization error'. In the inner exception, it gives the co ordinates of the erring field (e.g.: 5, 113). This de serialization error in my case is caused because of data type mismatch between the data sent by the service, and that in the .Net wcf proxy.

My question is how do we pin point the exact field based on the co ordinates given in the inner exception, if at all we are using any http debugger like Fiddler. I am finding it very difficult to exactly pinpoint the erring field based on the inner exception.

Thanks a lot,

IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Type or namespace error.


A couple of days ago I started getting an unusual behavior when compiling Website projects. I have referenced class libraries added to my bin folder that are also correctely referenced in using statements in my aspx.cs code behind. When I compile, I get the 

Error 4 The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?) C:\Dev\Fiscal_Portal\Implementation\FMS Portal Site_new\App_Code\BLL\DataTables.cs 1 7 C:\...\FMS Portal Site_new\

The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?)

error message that would typically be received when the dll has not been added as a reference or added in a using statement.

I can eliminate the error by adding an


HTTP Error 403 - Forbidden


(VB Express website directed me to ASP.NET Web Services which in turn redirected me to this forum).

 Hopefully someone can help me here...... 

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

What's up?????

Insert Error not helpful



I am using VS2010

When I try to updated or insert a record in my User table I am getting an error that does not make sense to me and I cannot figure out what is wrong.

Also, when I try to insert a new record I get a validation error saying that the Id is required. However it is an identity field in the db so it should not be necessary to send it to the server.

Could you please shed some light?

Error when updating. Supposedly updating ID without being asked.



Server Error in '/' Application.

Value of member 'ID' of an object of type 'Ref' changed.

Consider adding a new object with new identity and deleting the existing one instead.

I get this error whenever I attempt to update an entry. Even an entry that has had nothing altered. I have tried to circumvent it but I think it must be a simple oversight. How could I have caused an ID update using the Edit.aspx page of dynamic data? Thank you in advance for the help!

urlrouting - page not found error


I have a dynamic data site setup and running locally fine from vs 2008.

When i deploy to a remote windows 2003 server (IIS6), all the pages also work ok apart from one page/table.  I can access it's list page,  but the edit and insert pages throw 404 errors.

I'm thinking it's a url routing/hosting issue as i've copied back the database from the remote server and it all works fine on my local machine.

Is there anything i can do to debug this behaviour?
