C# - File.Create Is Appending To The File Rather Than Overwriting It?

Jul 19, 2010

I have the following code for creating a file if it does not exist and overwriting it if it already exists:

FileStream fsExe = File.Create(DestExePath, 4096);
BinaryWriter bw = new BinaryWriter(fsExe);

What ever I write to the BinaryWriter, it is getting appended to the "DestExePath" instead of overwriting the original file.

Overwriting ControlParameters Of DataSources In Code-behind?

Mar 8, 2010

I have an ObjectDataSource (but perhaps this question is the same for all kinds of DataSources which support parameter collections):

<asp:ObjectDataSource ID="MyObjectDataSource" runat="server"
TypeName="MyData"
OldValuesParameterFormatString="original_{0}"
SelectMethod="GetMyData" >
<SelectParameters>
<asp:ControlParameter ControlID="MyTextBox" Name="MyParameter" Type="String" />
</SelectParameters>
</asp:ObjectDataSource>

As you can see there is a ControlParameter bound to a TextBox on the aspx page. So the content of this TextBox is a parameter for my SelectMethod. But there is a special button on the page: When this button is clicked and a postback occurs I don't want that the DataSource extracts the content of the TextBox to control the selection, instead I want to set a specific hard value "x" as the selection parameter.

How can I do that? Can I "disable" in some way the ControlParameter when this specific button is clicked and set my special value instead? Or is there any other way?

IIS7 Overwriting Defined HTTP Header Values?

Oct 21, 2010

I am attempting to set the content-type of an asp.net .ashx file to text/plain.

When I run this through the ASP.NET Development Server, the content-type is properly set. When I serve it through IIS7, however, the content-type (and any other header values I set) don't come through (it came through as text/html).

The only value set in the HTTP Response Headers section of IIS Manager is the X-Powered-By attribute. I tried setting the content-type here, but that didn't work. But if I removed the X-Powered-By attribute, it was removed from the header.

Stop From Uploading Posted File?

Dec 25, 2010

I'm developing a httpHandler, in my source code if some conditions aren't met i would like to stop uploading file to the server ( for example file extension is not allowed)

When I try to quit ProcessRequest function with return null;, asp.net tries and uploads the file automatically before I quit the httpHandler...

How can I stop asp.net to automatically upload posted files?

Here is the list of thing I've tested so far and no luck:

public void ProcessRequest(HttpContext context) {
var worker = (HttpWorkerRequest)provider.GetService(typeof(HttpWorkerRequest));
..........
worker.CloseConnection();
context.Response.End();
Environment.Exit(0);
return null;
}

Is There Any Way To Stop A Check Out From Adding/removing File

Oct 19, 2010

I have an AJAX-heavy ASP.NET web application developed using .NET 4.0, using TFS as our source control. We recently upgraded our dev tools to use VS2010 and TFS 2010 exclusively, but now every time a file is checked out, we see visual studio reloading all the symbols, and all the sessions being dropped.

After putting some error logging code, we discovered the reason for the recycle is it reckons App_offline.htm is changing whenever we check out. This doesn't exist anywhere in the project, and my SO-fu has found some information about SQL Express making this file get created and deleted, so it's possible that's what's happening here.

It looks like I do have SQL-Express installed, but even disabling the services that are running, the problem persists.

Is there any way to stop a check out from adding/removing this file, if this is indeed what is happening? It's beyond frustrating to have the app recycle whenever I simply check out a file...

Stop IE Users Typing Into The File Upload Input?

Mar 17, 2010

My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted).

I am able to replicate this with the following ASPX code (with no code behind):

<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="fuTest" runat="server" />
<asp:Button ID="btnSubmit" runat="server" Text="Submit" />
</div>
</form>
</body>
</html>

(Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box)

Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields.

I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers.

Stop Source File Information Appearing In A Release?

Oct 7, 2010

I am building a web application. Here's what I do.

Set the solution Configuration Manager to Release. Thus all projects are building the Release version. Then I clean the solution and build all. Then I "Build Deployment Package".

When running the installed code from the deployment package I notice when there is a bug in the compiled source the source file appears! How is this possible, I am building the Release configuration. The source code is definitely not in the release so it must be in the dlls.

Is there a way to stop this?

Forms Data Controls :: GridView Item, Control Styles Overwriting Style Programmatices ?

Jun 9, 2010

I have a validation method which passes the control of a failed validation ( IE TextBox in the Gridview row ) to a method which adds a validationError style.This all worked fine until I decided to use declarative css styling on the properties of the columns in the page IE Control-CssClass="someClass".

WHen I click the update and do find an error, I pass the control to have the validationError class appended. but it appears the declarative setting overrides this when it gets rendered.

How To Get Chrome To Stop Caching When Working On An Aspx File In Visual Studio

Jan 4, 2011

I'm currently editing some html/css within a aspx file inside of Visual Studio 2010. I'm using Chrome as my browser. When I make changes inside of Visual Studio and save/ctrl + F5 to run it frequently fails to load the new updated .css file due to pulling old cached versions of the CSS.

I've used visual studio as my primary HTML editor before but when I work with pure html/css files I just save and refresh the file in chrome and it will refresh the updated css 100% of the time. I've only started to experience this problem when working with aspx files and running things via ctrl + f5. Anyone have any ideas of how I can fix this?

C# - Stop Site Reusing Session Id On Expiry - Force A New SessionId From The Global.asax.cs File?

Sep 30, 2010

I want to be able to log when a user ends their session on our application and record whether it was a sign out or a the session expired. I am using

cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));

to set a new sessionId on sign out, but when the session expires, the sessionId is reused if the browser instance is not closed. In my web.config I have used

<sessionState mode="InProc" timeout="1" cookieName="session" regenerateExpiredSessionId="true" />

but still get sessions reused. I can't kill the cookie in Session_end() because I don't have access because there is no HttpContext or request, so I can't reset it that way. how I can force a new sessionId from the Global.asax.cs file?

How To Stop A JavaScript File From Downloading Twice In JavaScript

Jan 27, 2011

I have two user controls and both the user controls refer a same script path:

<script type="text/javascript" src="test.js"></script>

then what happens when the first user controls load then test.js will download in client and when second user control loads then test.js file will download again.

How do I check to see if the JavaScript file is already downloaded so it doesn't have to be downloaded again?

If I include the JavaScript file from the server side:

Page.ClientScript.RegisterClientScriptInclude("test",
Page.ClientScript.GetWebResourceUrl(this.GetType(),
"test.js"));

then how could I make sure it isn't included twice?

C# - Why Does IIS Stop After A While

Jan 30, 2011

I am not too clear about the IIS lifecycle, but my general understanding is:

Every couple of hours IIS resets itself. This is apparently done so as to fix up any memory leaks, resource deadlocks etc. etc. ie. It seems to be a cleanup operation.

Every couple more hours (I think I read 23 hours) the server just stops listening to inbound requests and runs Application_End. An external page request will restart the app.

Can I get a bit more reasoning to why these behaviors occur? Especially with regards to item #2... My server runs internal scheduling behaviors which completely died last night. The reason was that Application_End occurs and no customer requests were happening to start the IIS server again. This seems weird. Why not just clean up memory leaks etc. and then keep IIS running exactly as it was?

Iis7 - How To Stop Cache

Jun 7, 2010

I'm seeing an issue of some static pages that are using the browser cache, which is not desired. To prevent caching, I'm setting

<clientCache cacheControlMode="DisableCache" />

in the relevant <location> tag in web.config

If I open the page in Firebug (in the Net tab), I see that the Response headers have Cache-Control: no-cache which is correct, but the status of the Response is 304 Not Modified! Isn't that a contradiction? How can I get it to stop caching (i.e. always send a 200 with content)?

C# - How To Stop ObjectDataSource From Binding Twice

Sep 30, 2010

This has been covered a couple of times, without a suitable answer:[URL]

I have created a custom paging data class that is used with an ObjectDataSource. In intial tests, I found it was performing worse than my old SqlDataSource code. Whilst investigating, I found that for every page load, the ObjectDataSource is being created and binding twice.

Investigating the links above led me to believe this could be a bug (or unexplained behavior) in regards to changing my GridView's column visibility in the OnDataBound event like so:

protected void gvContacts_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Pager && e.Row.Cells[0].Text != gvContacts.EmptyDataText)
{
e.Row.Cells[0].Visible = false;
if (Convert.ToInt16(lstSearchType.SelectedValue) == ADDRESS)
{
gvContacts.Columns[2].ItemStyle.Width = Unit.Percentage(30);
gvContacts.Columns[3].Visible = true;
gvContacts.Columns[3].ItemStyle.Width = Unit.Percentage(20);
}
else
{
gvContacts.Columns[2].ItemStyle.Width = Unit.Percentage(50);
gvContacts.Columns[3].Visible = false;
}
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["ID"] = "contact_" + e.Row.Cells[0].Text;
e.Row.Attributes["onclick"] = "javascript:selectRow($(this).attr('id').replace('contact_',''),2);";
e.Row.Attributes["ondblclick"] = "javascript:openContact($(this).attr('id').replace('contact_',''),''); selectRow($(this).attr('id').replace('contact_',''),2);";
//E-mail link
if (e.Row.Cells[4].Text != " ")
{
e.Row.Cells[4].Text = "<a href="mailto:" + e.Row.Cells[4].Text + "">" + e.Row.Cells[4].Text + "</a>";
}
//Birthday highlight
if (e.Row.Cells[6].Text != " ")
{
DateTime dt = Convert.ToDateTime(e.Row.Cells[6].Text);
DateTime now = DateTime.Now;
if (dt.Day == now.Day && dt.Month == now.Month)
{
e.Row.Cells[6].BackColor = System.Drawing.Color.FromArgb(255, 230, 160);
}
}
}
}

I use this event to customize the display of certain fields, as well as hide columns that are not pplicable during some search types. When I disable the event, the ODS stops binding twice. I can't really think of a way to get around this behavior. Has anyone else see this issue or developed a work around?
