I just deployed my first ASP app to a remote server (using SQL SErver) and some data entry forms are crashing when the associated table is empty. The PageLoad method is empty, but the error occurs before the page becomes visible. The limited run time error I see says page not found error 404. If I put a record in the table using Mgt Studio, everything is fine. The form contains two LInq data source controls that populate dropdown lists, but everything else was hand coded - no data bound controls at all.
There is no attempt to access the actual empty table until the data has been entered and the Insert button is pressed. I have made sure that the tables that use the datacontrols for dropdowns have data in them, even though this should not matter. I did not have this problem on my local machine when developing. In summary, page does not load when table is empty, even though I do not access the table when the page loads?????
This is the entire codebehind file, and yet the page cannot even seem to load.
I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet.
Can I create an incremental deployment package using either Visual Studio 2010 Web Deployment Projects or Web Deploy (Web Deployment Tool) .
I need to automatically select changed files from a source and destination or a change set on TFS and build a deployment package only with the changed files.
I have the following code that i call from the page behind code.
when no records are in the table i get an error message
invalidcastexception
conversion from type DBNULL to type Decimal is not valid
I would prefare if the procedure did not throw this error message and returned a value to notify me that no records found when zero records returned
Public Shared Function invoicetotal(ByVal CustEmail As String) As Decimal ' Dim selectcommand As New SqlCommand Dim CONNECTION As SqlConnection = MaintainDB.GetConnectionString Dim sel As String _
I have a textbox named txtOrderDate on my web page. I have a VB.net subroutine that saves various textboxes from my web page to my SQL table using a stored procedure. If a valid date is entered into txtDate, then my save works correctly. I have a column named OrderDate in my table. This is the column I am saving txtOrderDate to. OrderDate is defined as a date column and null is allowed.
But if txtorderDate is blank, my subroutine bombs saying cannot convert string to date. I tried various things like making the value of txtDate = DBNull.value if blank but nothing works. Seems like there would be an easy way to do this.
I have a table on my web form that I need to populate at runtime. I can do this ok and add controls to it, and all works well. However in between each row in the table I am trying to insert an empty row using the following:
[Code]....
[Code]....
NOTE: The litEmpty.Text in code is assigned the non-breaking space character
Anyway when the table is created and displayed, the empty row is not displayed.
I have a page that lists products from a table based on the querystring. So if I say foo.aspx?fam=1 all the products from family 1 will be listed. How can I make my code list all the values if query string is empty? My SQL command would have to be different...can't really see how I can do this.
I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?
i designed a gridiview, within that ItemTemplate i drew an table then tr then some of td's, now the problem is after every row im getting one empty row. below is my code
Our ASP.NET 2 web application handles exceptions very elegantly. We catch exceptions in Global ASAX in Application_Error. From there we log the exception and we show a friendly message to the user.However, this morning we deployed the latest version of our site. It ran ok for half an hour, but then the App Pool crashed. The site did not come back up until we restored the previous release.How can I make the app pool crash and skip the normal exception handler? I'm trying to replicate this problem, but with no luck so far.Update: we found the solution. One of our pages was screenscraping another page. But the URL was configured incorrectly and the page ended up screenscraping itself infinitely, thus causing a stack overflow exception.
I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN DECLARE @Accounts nvarchar(MAX) SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules] WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5 IF ((@Accounts = '') OR (@Accounts = 'All')) SELECT @Accounts = null
BEGIN Select @@ROWCOUNT as Priority2 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority3 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority4 END IF @@ROWCOUNT = 1 BEGIN Return END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.
I am trying to populate a gridview using two tables. I also have a strongly typed dataset and used the method on this page: [URL] the problem is that, when i try to use two table the gridview does show up (I checked through debugging that the datatable comes back as empty).
I converted a ASP.Net website to ASP.Net web app and changed the framework from 2.0 to 3.5
The web application works fine in Visual studio. However, If I compile the app in a dll, and try to reuse its middle layer in another web project, All the classes that have a static variable crash. Code like:
What is happening is I'm trying to process international characters, but the code is falling through (giving up?) and replacing the field with a blank (well, I guess the screenshot is at the bottom)... The customer recently asked for support for Polish characters, and gave us a list of which ones he wants added.
This is the entire function:
Code: Protected Function chkExtchars(ByVal name As String) As String Dim j As Integer = 0 Dim dt As New DataTable Dim c() As Char = Nothing Dim n As Integer Dim nc As Char Dim newname As String = "" dt = HttpContext.Current.Session("xChars")
[Code] ....
But maybe it needs to be sequential? (the numbers on the far left?)
I have a few years experience developing C#, I have been asked to learn ASP.NET for a web development project. Does anyone know of any crash course tutorials to enable me to achieve this quickly, either internet or literature based?
a look at this site.maimei.chAfter 5 times opening a new site via ajax (fancybox) it crashes in IE?ne little thing is that i load a whole asp.net site via ajax in the new window. so viewstate and other overhead is there twice after. could this be the problem? if yes, why just after 5 times?.is it possible to call just the content of an specific element via ajax? may be just the innerhtml of the body element of the called site?
I have a page that utilizes an IFrame to display another page within the first one. I am using ASP.NET 3.5 and when I click on a button to do a post back event, it causes Internet Explorer 7 to throw an error.
My project uses swfobject.js to display a Flash animation. But in Internet Explorer 8.0, if I try to refresh the page, the browser window closes.
To re-create this problem:
Download a sample solution from: [URL] Unzip the solution and open it in VWD 2010 or VS 2008 Pro Be sure VS is configured to use its development server (not IIS) Select Debug | Start Debugging (F5) When the Default.aspx page opens, press ctrl-F5 to refresh the browser window The browser window will close with no warning or explanation So far, I haven't seen this behavior in Firefox, and nobody has reported it in any browser other than IE-8.
Users get firsly to the step0 page, where they fill some info, the page updates, they fill some more, and then get redirected to step1 page.
Problem is that upon getting to the Step1 page, if the user clicks on the back button, then he gets to the last stage of the step0 page, which uses sessions and variables that are no longer existing, what causes a crash.
I'm looking for an elegant way to make sure that with each page visit, the page will restart itself to start phase.
I have this idea maybe twitching the Page_Load function, something about the is_post method, but since each page's post back hits this function,
After upgrading an asp.net application to 2.0 from 1.1 I am receiving a large 100+MB .tmp file in C:Temp on the web server when the w3wp process serving that application crashes. If you open the file it looks like it is some sort of dump file. how to turn this off. I know what is crashing the application and process.
I'm trying to bind a nullable bit column, which at the moment is mostly null, but I need to somehow convert the null to a 'false' on runtime because it doesn't bind to a checkbox if it's null. But, I am currently unable to change the default value and update all records accordingly - is there a way to do this in runtime?
i have a some Records in My Data table. i want to get Distinct Records so i have used data View for That. when i look in into DataTable.DefaultView it Shows Empty.
