Sending A TCP Packet To Localhost In Page On Win 2008 R2?

Feb 8, 2010

We have a windows service running that listens on e.g. port 9999. Now we want to be able to send a TCP packet through an ASPX page to that service. Both the service and ASP.NET WebApp run on the same server.

The problem is that this works fine on my dev machine (without IIS though, through Visual Studio Web Server) and on our older Win 2003 Server machine. But it doesn't work on our new Win2008 R2 Server. The packet just won't arrive.

I'm absolutely clueless as to what the problem may be. I'm the only one wanting to send TCP packets through an aspx site.

What I have tried so far:

1) Changing the identity of the corresponding Application Pool

2) Disabled the Firewall

3) In web.config set the trust level to "Full" (which seems to be default anyways)

WCF / ASMX :: Send A JSON Data Packet Back To Requester?

Mar 7, 2011

We have an exisiting Web Service which receives SOAP requests and returns the data accordingly. However, we have a new project which requires the same information but the Android SDK doesn't support SOAP so we need to use JSON. As JSON is just a data container format, I need to write a new module to replace the SOAP WSDL which receives a querystring from the Android app and then processes the data and returns it in a JSON packet. The problem is that having never used JSON I'm unsure as to how I return the data to the app in JSON format. Does anyone have any examples I can look at in VB.Net or C#?

Forms Data Controls :: Change The CSS Class Of The Row - Unexpected GridView Alternate Row

Jan 21, 2010

I'm trying to change the CSS class of the row that is in edit mode. I've managed to get it working, but it only works for alternate rows. I'm totally stumped as to what could be causing it to behave like that. I've attached what I think is the relevant code below

[Code]....

protected void grdList_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.CssClass = "row";
}
if (e.Row.RowState == DataControlRowState.Edit)
{
e.Row.CssClass = "rowEdit";
}
}
.grdView tr.row:hover
{
background-color: #999999;
font-weight:bold;
}
.grdView tr.editRow
{
background-color: #999999;
font-weight:bold;
}
.rowEdit
{
background-color: #999999;
font-weight:bold;
}
.grdView .row .edit, .grdView .row .delete
{
display:none;
}
.grdView tr.row:hover td .edit, .grdView tr.row:hover td .delete
{
display:inline;
}

Forms Data Controls :: Store Format Or Format Output Of Text Field Into Datalist

Mar 29, 2011

I have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:

<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />

Indicate Error Once There's An Unexpected Parameter?

Mar 30, 2011

My ASP.NET application will have to handle HTTP GET requests that will have the following URL format: [URL] currently the requirement is to validate that there're no parameters in the query string except id and indicate an error like "unknown parameter P passed". Is such requirement a good idea? Will it interfere with some obviously valid cases of using the application I haven't thought of?

Getting Unexpected Error While Transferring Data?

Feb 19, 2010

I am transfering data from DB server to second DB server using one test page.

But i am getting following unexpected message ....

The CLR has been unable to transition from COM context 0x205480 to COM context 0x2055f0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

Unexpected Postback Happening On A User Control?

Feb 18, 2011

We are creating a new user control using a boiler plate template for our application. We noticed that anytime a textbox on the new user control has a focus and the enter key is pressed, the form executes a postback. This happens even if the AutoPostback on the text box is set to true. No other user controls in our app behave this way. What could be some of the places for me too look?

Comparing 2 Linq Applications - Unexpected Result

May 16, 2010

I drafted 2 ASP.NET applications using LINQ. One connects to MS SQL Server, another to some proprietary memory structure. Both applications work with tables of 3 int fields, having 500 000 records (the memory structure is identical to SQL Server table). The controls used are regular: GridView and ObjectDataSource.
In the applications I calculate the average time needed for each paging click processing.

LINQ + MS SQL application demands 0.1 sec per page change.
LINQ + Memory Structure demands 0.8 sec per page change.

This Is shocking result. Why the application handling data in memory works 8 times slower than the application using hard drive? Can anybody tell me why that happens?

C# - TreeView Control Unexpected Event Behavior?

Apr 16, 2010

In the MSDN is writen about TreeNode that:

"By default, a node is in selection mode."

"To put a node into selection mode, set the node's NavigateUrl property to an empty string."

"When a node is in selection mode, use the SelectAction property to specify which event or events are raised when a node is selected."

"Setting TreeNodeSelectAction value TreeNodeSelectAction.Select Raises the SelectedNodeChanged event when a node is selected."

Here is the problem and possibly a bug in the control:

When I set the TreeNode object PopulateOnDemand value to true and call the Collapse() function on that node.Then the TreeNodeExpanded event is raised in addition to the SelectedNodeChanged event.This is in complate contradiction to what is writen in the MSDN.According to the MSDN this sould happen only if TreeNodeSelectAction Property is set to TreeNodeSelectAction.SelectExpand value.

Here is the code:

<asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False"
onselectednodechanged="TreeView1_SelectedNodeChanged"
ontreenodepopulate="TreeView1_TreeNodePopulate"> [code]...
