### Has anyone experienced problems using a reorder list control in Chrome/Firefox?

I have three reorder lists on a page, one does not want to work. It is no different to the others, but is behaving like it is not enabled.

All working fine in IE 7 + 8.

Any ideas appreciated :)

I am using the code below to enable clients to download a .csv file from my server.The problem I am having is that when the file is saved to the client computer the file name is prefixed and suffixed with an underscore which leads to a file type of .csv_ which is obviously not a recognised file type.How can I strip the underscores from the file name at the transmit stage?        Dim FileName As String = LstBox1.SelectedItem.ToString        Dim FilePath As String = "~/temp" & FileName        Response.Clear()        Response.ContentType = "text/csv"        Response.AddHeader("Content-Disposition", "attachment; filename=\" & FileName & "\")        Response.TransmitFile(FilePath)        Response.End()

### Response.TransmitFile virtual directory?

I can use Response.TransmitFile on my p.c. using VS2008  fine. But when I moved my code over to the server it won't work. Does the path have to be a virtual directory?

Lets assume you have 1 serverA with dir D:\ExcelReports and another serverB thats the webserver. So to transfer a file you would need something like Response.TransmitFile(D:\ExcelReports) ?

### Using response.outputstream.write to stream large file fails in firefox

Hi,

I have some code to stream files (for security of the files), the code works for all files in IE, and small files in firefox. but If the file is large (eg 750Mb) firefox hangs before it shows the open/save dialog box.

However if i take out response.clearheaders and the response.flush in the code it does download but all the files downloaded by firefox are corrupt because the file size is too large.   Filenames are guids but I took the "-" out incase that was an issue.

If any one can shed some light on this I would be very grateful.

Function is Below.

Private Sub StreamFile(ByRef response As HttpResponse, ByVal sFile As String)
Dim fs As FileStream = Nothing
Dim sFileName As String = Path.GetFileName(sFile)

Dim oFile As New FileInfo(sFile)
Try

Catch ex As Exception

LogError(ex)
End Try

response.Clear()
'response.ClearHeaders() 'makes file size wrong in firefox

'To forcefully download, even for Excel, PDF files, reg

### Sharepoint 2007 Survey - View response - Firefox layout issue

Hi,

I've got a survey running on a Sharepoint 2007 site but when I open the view response page (DispForm.aspx) using Firefox 3 the layout is incorrect - The question text is not wrapping and so I've got one massively wide column.

In both Safari and IE this isn't a problem, it works fine - the problem is Firefox capability.

Has anyone come across a fix for this? I've spent the last couple of hours searching on the net with little success.

### Response.TransmitFile stops rest of page execution

Hi

i am trying to have a download on my page. I have implemented the code below but code execution stops after the download message pops up, even if i press save or cancel, nothing happens after that.

Response.Clear();
Response.ContentType = "application/octet-stream";
Response.TransmitFile(lFile.FullName);
Response.End();

I have tried it a few times without Response.Clear() and Response.End() but it didn't make any difference to take these off. Is there anyway I can achieve this without having to using an IFrame?

Any suggestions will be very much appreciated.

### Top .NET Performance Problems and how to avoid them

Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, inefficient custom code

### Response.BinaryWrite help needed

Hi all

Im new to .NET and stuck now, so i hope anyone can help my with my problem.

I have a MS SQL database where i have stored some documents as Binary data. I cant figure out how to retrieve them and show/download them in my browser.

I found some guides online and have try to put something together.

private void Write()
{
int id = 0;
string strID = Request.QueryString["id"];
int.TryParse(strID, out id);

var db = new ModelDataContext();
var doc = db.DocumentDatas.Where(x => x.ID == id).FirstOrDefault();

Response.BinaryWrite(byteArray);
}

How do i fill the byteArray with the data?

### Response.Redirect slow

I'm in the middle of migrating servers and on the new server Response.Redirect is extremely slow. It takes around 20 seconds for the browser to get the redirect. This is something that was quick on the existing server. It's an ASP.NET 2.0 application, both servers are running IIS6.

Additionally, if I "manually" do the redirect, it's fast. For example:

Existing way:

Response.Redirect(url);

takes around 20 seconds on the new server

New way:

Response.Status = "302 Moved Temporarily";Response.AddHeader("Location", url);Response.End();

is fast on the new server.

Any ideas why Response.Redirect would be so slow on the new server?

### Visual Studio 2008 Memory problems

My memory in task manager reaches about 900,000K  and I don't know why it does this. Definately slows everything down, especially when I rebuild my tableAdapters, takes about 30 seconds sometimes to rebuild the project.

### Problems with Forms Authentication in DD 4 site

Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

<authentication mode="Forms">
</authentication>

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!

### Problems posting to a package

Hey Y'all

I'm currently creating a program that accesses a mysql package to add data to a few tables.  I'm currently getting an error that says  "

## ORA-01403: no data foundORA-06512: at "JESSE.PKG_WORKPLAN", line 42ORA-06512: at "JESSE.PKG_WORKPLAN", line 177ORA-06512: at line 1

"

These lines are

42: INSERT INTO WP_PROJECTS_USERS (PROJECT_USERS_ID, FIELD_UNIT_ID, PROJECT_ID, USER_ID, START_DATE, DESCRIPTION)

Checking these variables in my asp.net page they are all receiving parameters.

Is there a  way to see what the database is actually receiving from the asp.net page?

Or is there another thing to be looking at?

Thanks!

### URL Routing and Existing HttpHandler problems

Hello everyone,

I have a problem:

I am currently using 2 features:

1. HttpHandler

Registering the path="res.aspx" verb="*"

2. URL Routing:

Registering with this pattern: "Company/Edit/{*companyId}","~/CompanyEdit.aspx"

In my CompanyEdit.aspx page, I used httphandler res.aspx to generate some images at client.

• res.aspx?img=1
• res.aspx?img=3

Now the problem is here, the page is load success with companyId = "12345", but when the images was loaded at client, it loaded the CompanyEdit.aspx again and show error with wrong id.

I have debug and find the problem that because when image's urls were generated to client with url=res.aspx?img=1, url=res.aspx?img=3, the asp.net will understand that they are Company/Edit/res.aspx?img=1, Company/Edit/res.aspx?img=3 when it maps with URL Routing pattern.

=> So the CompanyEdit.aspx was load again with wrong id (id now is "res.aspx").

So, do you have any ideas to solve this problem, or other design.

Thanks, and best regard

### ASP.NET 4 precompilation problems

Hello!

We used ASP.NET precompilation (first manually, then with VS2008 WDP) with .NET 3.5 almost (see below) successfully.

After we moved to 4.0, the precompilation no longer works properly. The precompilation process itself succeeds, and the website works, but it consumes about twice the CPU it does without any precompilation. We use non-updatable precompilation (so webpages get compiled completely).

Our internal profiling tells us that most of the threads spend their time within variations of the following stack:

...

System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultFromCacheInternal(System.Web.VirtualPath virtualPath, bool ensureIsUpToDate) + 0xa2 bytes
System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0x5b bytes
System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(System.Web.HttpContext context, System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0xcb bytes
System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResult(System

### Problems converting VS 2003 project to VS 2008

Hi!

I'm having problems converting a VS 2003 project to VS 2008 (tried 2005 as well, same problem). There are several problems;
a) I don't have VS 2003 installed.
b) The project is a web service, however I'm not sure what type of VS project it was created as.
c) The general knowledge about the project setup is..slim.

I get a error message using the conversion wizard, however, I'm not familiar with the tool and I cannot quite find any good information on Google for it, so I am left with a error message I do not understand.

Conversion Issues - myProject.csproj:
Unable to open the Web site 'C:\local\path\to\project\myProject.csproj'. The Web site 'C:\local\path\to\project\myProject.csproj' does not exist.

The web service is not intended to run on the dev machine, it is copied to a test or a prod server. However, I do not know how this was done previously. I'm thinking that in order to convert, it has to access the server on which it should run (which is set somehow in a config maybe). But that doesn't actually make any sence..

If anyone could shed light on this, I would really appreciate it.

Thank you.

I am trying to have the selected item in the menu be noticeable different than the other items.  I am able to change the border as in the samples, but nothing else. I would like the selected font color to change as well as the background image / color.  Here is a sample page and style sheet.  Any help is greatly appreciated.
