- Use Excelsheet in ASP.NET for calculationHi,
I want to use a difficult Excelsheet as source for my calculation in a
ASP.NET (C#) page. I have 5 input fields on my ASP.NET page and when I press
the submit button I want to put these values into the sheet in cell A1:A5.
And then in A6 an awnser will appear, this awnser needs to be shown on the
ASP.NET page.
Is this possible? And how? (examples) And what serverside software do I need?

- How to set position of a web control depending on other control's position at run-time?Dear all,
Take the simple example of my case: There're two label controls and the
contents are assigned dynamically. I want to put the second one on the
right-hand-side of the first one without any gap between them. Since I
don't set the width property of both controls at design phrase to make them
"AutoSize" enable and avoid word-wrap, I can't get the width of the first
control to determine "position-should-be" of the second one at run-time.
Though somebody has designed a complicated method to calculate the actual
width of a string according to text content as well as font size, I found
that the size represented for label control is "small, medium, large, etc"
instead of the actual point / pixel size. I don't know how to convert
something like "small" to point / pixel size to start the calculation.
Does anybody have good idea to manage my problem? Thanks for your attention
and kindly help!

- C# ASP.NET Thumbnail Generator issueGreetings all,
I am having a problem with an asp.net application using C# which is a
thumbnail generator. Here is the code used...
http://www.eggheadcafe.com/articles/20030515.asp
It works fine for .jpg images but for some reason it doesn't work with .gif
images. The author of the article says it works fine for him but I can't get
it to work. I was wondering if anyone here can shed some light?
I have my permissions set for read, write, etc.. and as I said it works fine
for jpg's.
Thanks, David

- Getting/Setting JS VarsHello....
I am working on a control that involves a fair amount of javascript... its a
editor pain of sorts using a textarea.
My problem is... setting the contents of the textarea from a property, and
when the .Text propery is read, how to have that read the js var that
represents that?
I was told I could render javascript with the var set, on postback with js,
stick the js var, into hidden form input and parse accordingly...
then I was told this was wrong and was told to override
onCreateControlCollection and have it add HtmlInputHidden or something...
I know its probably very common, and so I hope to get the best way to do
this
THanks

- Multiple data setsHi,
I have one page with four reports in separate datagrids. I need to generate
one report in excel format.
I wrote a script that generate reports for every datagrid separately.
Now, what I need is to create one master report and to combine these four
datagrids into one datagrid programmatically (is it possible?) or to combine
datasets before biniding and then bind this one dataset to one datagrid.
Any help will be greatly appreciated.
Thank you,

- SSL for very simple security need in web service appI'm looking for a nudge in the right direction.
We have an order processing system that currently has a simple ASP.NET web
interface. Various clients who want to place orders already have a userID
and password specified within our application (i.e., not Windows
authentication) that they must supply in order to logon to their 'account'
and submit orders for themselves. They communicate from a browser over the
public internet. The browsers/server utilize SSL for encrypting the web
traffic.
We'd now like to implement this functionality as a web service to interact
with some desktop applications that can generate orders. We'd like to have
the remote app simply transfer the data, presumably in an XML format that we
already have defined, over the public internet, providing their userID and
password.
My question is: if we just add the userID and password in the XML
schema/data, is the SSL layer sufficient to ensure that anyone who might
intercept the traffic en route would not be able to determine the UserID and
password? Once we have the XML data in our app, it would be a trivial matter
to determine if the data is coming from a source that had a legitimate,
active UserID and a valid password. And that's pretty much all we'd need.
I read about WSE, WS-Security, etc. and it all seems like so much overkill
for my needs -- but I can't locate a single, simple scenario that looks like
what I have in mind here.
Any direction would be greatly appreciated!

- FCKEditor not working in contentplaceholderI'm having trouble getting FCKEditor to work in a contentplaceholder.
The code works fine on a single page, but fails in a master/details
configuration. Specifically, FCKEditor won't render when embedded in a
contentplaceholder. I tested it both on IE 7.0 and FF 2.0.0.11 with
ASP.NET 2.0 and 3.0 using FCKEditor version 2.5 and also .NET version
2.2.
FCKEditor actually requires a dll (FredCK.FCKeditorV2.dll) in the bin
directory. Are there any special registrations steps required when
binding an assembly control into a details page? All samples I looked
up are implemented on a single page. TIA for any hints.
Sample (works):
<%@ Page Language="VB" ValidateRequest="false"
AutoEventWireup="false" %>
<%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2"
Assembly="FredCK.FCKeditorV2" %>
...
<form id="form1" runat="server">
<FCKeditorV2:FCKeditor id="FCKeditor1" BasePath="~/FCKeditor/"
runat="server" />
<br />
<input id="Submit1" type="submit" value="Submit" runat="server" /
>
</form>
Sample (fails ie. FCKEditor not rendered):
<%@ Page Language="VB" MasterPageFile="~/Site.master"
ValidateRequest="false" AutoEventWireup="false" Title="Untitled Page"
%>
<%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2"
Assembly="FredCK.FCKeditorV2" %>
<asp:Content ID="Content2" ContentPlaceHolderID="CPM1" Runat="Server">
<FCKeditorV2:FCKeditor id="FCKeditor1" BasePath="~/FCKeditor/"
runat="server" />

<input id="Submit1" type="submit" value="Submit" runat="server" />

- Internet Explorer & Response.RedirectAnyone know how I can figure out the figure out the response.redirect trail a browser goes through when I'm using response.redirect on the server. Right now Internet Explorer just automatically redirects, I need to figure out, on the client, the pages it is being told to go to. Yes I know I can look in the address bar, but say the Response object is redirecting 3 or 4 pages per Request. I need this for a debugging issue.
Thanks

- Best way to implement custom control: Repeater vs. Anything ElseI am struggling with implementing somewhat complicated UI web-control. I
explored Repeater, but I am not sure if it's the best way to go. I am leaning
towards writing my own custom control and creating elements on the fly
dynamically.
I have a control that needs to display 3 columns and n number of rows
depending on number of records. Sounds simple. But each Row has a control
with its own data source binding and value must be selected based on data.
Each row can be removed by the user or new row added. So far Repeater can do
all that, and I developed a prototype that does it.
But The problem is that I need adjust colspan=x for different. If there's no
previous data, I need to hide 1 column which has delete button and do colspan
= 2 on the last column. So user has to create a new record. I can't find an
easy way to do it, rather then writing custom code on ItemDataBound event or
ItemCreated and adding HTML text programmatically. But what's the point
having Repeater control? I might as well write my own implementation.

- parameter passing asp.net vbhi,
I'm a relative newbie to .net but have been an asp developer for a few
years. I'm starting the slow and somehwat painful process of learning
how to do everything I used to do in asp in .net.
i'm using visual studio and am simply trying to do the following:
Pass a value into a stored procedure or a sql query which has been is
passed via a querystring.
I've achieved this by setting the value of the parameter in the
desinger generated code but I would like to be able to handle this in
the page_load. I'd like to check for the existence of a paramater and
pass this value to the query.
I'm sure it's really easy, it certainly is in classic asp but i'm
really struggling with this one.
Anyone help?

dotnet-framework-aspnet >> learn regular expressions
I have found RegexBuddy (of all the tools I've tried, have, and use), to be
an invaluable tool, both for learning and working with regular expressions.
It is not free (29.95), but can be downloaded for a trial, and is more than
worth the price. It has quite a number of testing and building tools, and an
excellent reference with tutorials as well. It has a Graphic Expression
Builder, which displays a regular expression in a tree view that has a
description of each element. It can be found at http://www.regexbuddy.com/.

- Is this the correct Multi-threading approachHi,
I need to kick off a long running process in response to a user action
on my website. I'm not fussed whether it completes correctly or not (it's
just sends a load of emails) but I want control of the webpage to return
immediately to the user.
So all I do in my Server side event handler for the page is :
SiteUsers su = new SiteUsers();
Thread background = new Thread(new ThreadStart(su.EmailUsers));
background.Start();
Will this give me any undesirable side effects in ASP.NET? As I said earlier
I don't care if it completes or not so I've not used any Callback to tell me
when it's done.
thanks

- Running Windows Applications Via World Wide WebHello,
I apologize for my lack of knowledge in this area, or if this is the
incorrect group to make this post in.
I am designing a website for a client who sells Windows-based image
processing software. They want users to be able to upload an image to
the site, get the image processed by the application, and show the
user the processed file. Is this possible, and if so, how? The
application has a GUI, so I am guessing that it would not just be a
simple matter of piping the image data...
I am an experienced Perl and PHP programmer and web designer, but I
usually work on Unix servers and haven't tackled a problem like this,
so I'm not sure how this would be done. Any information you could give
me would be very much appreciated, even a link to a site where this is
discussed. Thanks in advance for your help.

- datagrid linkbutton event and firefoxI inherited some code with a datagrid being populated at run time (ASP.NET C#
page), and each row in the datagrid has a linkbutton. In IE, clicking on the
linkbutton displays the proper piece of content, in an IFRAME when the page
reloads.
In Firefox, I get a blank page. I can see HTML if I View Source, but it's
not the same HTML I get when using IE. It appears the event for the click on
the linkbutton is not running when using Firefox.
The datagrid settings:
AutoGenerateColumns = false
Enabled = true
EnableViewState = true
private void HelpChoicesDataGrid_ItemCommand(object sender,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
if (e.CommandName == "ViewHelp")
{
e.Item.BackColor = Color.DarkGray;
HyperLinkToSelection(Convert.ToString(e.Item.ItemIndex));
}
} // End HelpChoicesDataGrid_ItemCommand
protected void HyperLinkToSelection(string bookmarkIndex)
{
System.Text.StringBuilder jScript = new System.Text.StringBuilder();
jScript.Append("<script language=\"JavaScript\">");
jScript.Append("location.href=\"#");
jScript.Append(bookmarkIndex);
jScript.Append("\";");
jScript.Append("</script>");
this.RegisterClientScriptBlock("Bookmark", jScript.ToString());
} // End HyperLinkToSelection
Any ideas?

I have a couple of pages where a user enters information.
At the last page i want to present all data, and let the user confirm it.
I dont want to use a response string that adds upp everytime
Like www.myweb.net/do.aspx?quiz=lsl&ordering=1 etc and when going from the

Should i create a class and store all the data, or is there another, smart

Also, there are files with the extension of .resx which don't seem to be required when I post the completed projects to the web. Some of them also seem to be constantly 'checked out' from the Source Safe but don't check back in when I tell it to check everything in. Are these files required

- DataTable or DataSet? OleDB or Sql..?Hello
I was wondering if you guys could help me out...... I might have mixed the
things up so bare with me.
I was wondering if I should use datatable or dataset when displaying data in
my asp.net page? Mostly i dont need paging, just showing data...... and does
both support paging in the datagrid control if i need it?
and which one is faster? I "always" use stored procedures for select,
insert, update, delete........ so I basically just send parameters to them
and let sql-server do the work, and not having some thing i modify before i
send the result to sql-server. (hope i explained correct there).
And second....... Should I use OleDB Provider or "regular" Sql-"class" (?)
to connect and execute things against my sql 2000 server? I've always used
OleDB provider when working with regular asp. Any pros/cons?
TIA

- Application Tracing for a Single Session ?I'm trying to implement application tracing for a single session but am not
having much luck. I'd like to isolate TraceContext application level
messages for a single session and have them logged to trace.axd (or even a

pretty uncooperative. I have also been looking at the WebPageTraceListener
class but am not sure if it is much use in this quest. Any ideas?
TIA
