Why would enabling trace.axd change the way an app works?

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
Hi Guys,We have a page with a flash control on, on this page the flash control allows the user to upload a file and gives a progress report. When done the tool calls another page called SaveUpload.aspx which saves the file. The tool was not able to call this page for some reason and as soon as I turned on tracing it allowed the page to be called.Anyone seen behaviour like this before?Cheers,Pete

Trace to TraceTool works in win2003 but not Win2008


We have a website with code like Trace.WriteLine....
we can view the traces in a tool be the name of TraceTool when the switches are turned on in the web.config and when using XP or Windows 2003.
..but we cannot see the traces in Windows 2008.  We turned off the firewall and still no messages.

Is there anything that needs to be done to Windows 2008 to allow the messages to pass from the web to TraceTool?

Thanks in Advance.

Change in transaction replication articles without enabling the enable Schema Replication to true


We have a transactional replication database where in we have set the schema change property to false. Now we have added a new column and to the table and wanted this column also to be replicated. But before enabling the allow schema replication parameter, we have altered the article added a column.

Now we reliazed that we have not enabled the sehema replication option. The database is very large and reinitializing the subscription remains our last option.

Could anyone suggest us the right way forward.

Thanks in advance.


PageData weirdness, works, then doesn not work. Change the 'index' name and it works again


I'm facing a weird issue. I have a page "add.cshtml" in wich I create a PageData object like this:


PageData["myObject"] = new { Message = "some msg", ID = 1, Name = "some name" }

In that same page, I pass the object to a RenderPage:



@RenderPage("form.cshtml", PageData["myObject"])


In "form.cshml", I simply call values like this:


<br />

When I call "add.cshtml", it works, then for some reason, at some point, I get an error stating: "object" does not contain a definition for Message, if I comment the @PageData["myObject"].Message, error occurs on next property.

When this happens, I change "myObject" to another value in both files, and no more compilation error.

Why does this happen?

Enabling Users to Maintain SharePoint Content

When SharePoint is installed as a corporate intranet, there is a considerable amount of effort involved in maintaining the content to keep the site relevant. As we discussed in the first few parts of this series, SharePoint has many built-in features to reduce the burden on the site administrator.

Some areas of the site usually contain less-dynamic information. Internal memos and corporate policies are common examples of this information. One option for this information is to post these documents in a document library. Documents in a library are often stored in a few different formats: Word, Acrobat (PDF), or HTML. Each of these formats has its drawbacks.

How to Localize Windows Forms and Change the Language at Runtime

Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project

Code works on aspx but not ascx


Not sure which category to put this question in, so I will put it in here.

Just to give you an idea of the layout of my solution, I have the main project, along with 2 class libraries, BLL and DAL.  (Business Logic Layer and Data Access Layer)

The BLL refers to the DAL and the main project refers to the BLL.

I had a test website and the code worked fine, but the same code will not work on the real project. The only difference is that in the test project, the code was on an aspx code behind, whereas in the real project, it is an ascx code behind (Web User Control )

The code is:

Dim connectionString As String = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString").ConnectionString
        Dim recordEntry As New UserRecord(connectionString)
        recordEntry.UserName = "TestName"
        recordEntry.BMI = bMI
        recordEntry.BMR = bMR
        recordEntry.FTM = fTM
        recordEntry.TDEE = tDEE
        recordEntry.TodayDate = dateForToday

Dim connectionString As String = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString").ConnectionString

Selected to change the background color of the page

Bug: Does not change column type from nvarchar to ntext


Scenario: If you create a table with a column of type nvarchar, populate it with some content and try to modify it using the WebMatrix editor, from nvarchar to ntext, it does not display any error message or warning that this is not possible. It silently saves and reverts the change, back to nvarchar. Wasted some hours on this issue as I thought my column was ntext, but in fact was still nvarchar.

Expected behavior: It should change to ntext, or if SQL CE doesn't support that, it should notify the user that no change was applied.

How to change the default page base class?


I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.

I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.



SqlDataSource how to change the stored procedures at run time



Is it possible to change the select, insert and update stored procedure of an SqlDataSource at run time. I don't mean to change the definition of the stored procedure, but I mean to change the assignment, i.e. To change the select stored procedure from "selectSP1" to "selectSP2" at run time. Is it possible?



Nested Tracers - is there a way to only log the outer trace?



I have some nested tracers. The outer one has a category of 'PageTrace' and the inner ones have categories of 'DBTrace'. When I set the outer category source to 'All' I get both traces. When I switch on the inner trace, I just get the inner trace.

So, my question: is there any way to just log the outer trace events, i.e. the Page Traces.




HttpHandler works with Visual Studio Development Server debugging, but not otherwise


Hi all,

I'm new to HttpHandlers.  I am writing an HttpHandler that reads uploaded files directly from the request stream to provide progress that can be queried using an AJAX request.  For large files, this seems to be faster than having ASP.NET load the file contents into Request.Files and then streaming the file from there to wherever it goes (Linq to SQL into a VARBINARY column in an SQL Server database.)

My HttpHandler works perfectly when I'm debugging using the Visual Studio Development Server, but doesn't work otherwise.  The application pool for this application in IIS 7 is set to run in Classic Mode, and the Handler Mappings screen in IIS says that I must manage managed handlers in system.web/httpHandlers. 

I set up in my applications Web.config file.

<add verb="GET,POST" path="*.upload" type="Namespace.For.UploadHandler, AssemblyForUploadHandler"/>

It works great, so long as I don't debug with the "Use Local IIS Web server" option.

What else do I need to do to get this to work?

dynamically change column names in Crystal reports


I need to develop 3 pages.

On the first page user defines atmost 7 column names to be displayed on the report. I'm saving these names in a Sql DB table 'Columns' with Column_Nm and Column_ID as Table columns.

On the second page I'm retrieving column_Nm from the table and displaying them on the page so that the user enters the data. This data is saved in another table 'Summary' with the Columns column1 through column7.

on the 3rd page I need to show a report of 'Summary' table.

How do I dynamically replace column1 through column7 names with that of 'Column_Nm' on the report?

Any help/suggestions would be appreciated.
