I'm currently buidling an ASP.NET application that requires custom HTML emails be sent. I was going to use "Sever.Execute" to capture the result of an aspx template execution and use it as the body of an HTML email. This works, but it only works if it is called from the "Page_Load" Sub. As soon as I call it from an event sub it fails and returns a "Corrupt ViewState" Error. Is this normal? Does "Server.Execute" only work in Page_Load? Is there another/better way to do this? Help is appreciated.
Code:
**** This Works ****
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
SendItDude()
End Sub
**** This Doesn't Work ***
Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click
SendItDude()
End Sub
Public Sub SendItDude()
Dim EM As CarSystem.Emailer = New CarSystem.Emailer()
Dim writer As New StringWriter()
Dim x As Integer = 1
Dim List(x) As Integer
List(0) = 3332
List(1) = 3332
Server.Execute("../Assignpreview.aspx?car_id=7", writer)
Response.Write(EM.Email_it(8, List, 3332, "This is a test", writer.ToString()))
End Sub

Thanks for nothing, I solved it myself, well sort of. First of all Server.Execute is an ugly little function. If you don't have to use it don't.
You can't use it unless it is in the Page_load. This might seem obvious to some, but I couldn't find any documentation on this fact. There is viewstate conflict. For some reason you can't have more than one viewstate field on a page at one time. Who knew? If there was a way to not place that field on the page being executed it might work, but simply "disabling" it doesn't remove the field, it only disables the controls from saving to it.
So what I did was, on Page_load execute the aspx page that I was trying to use as an email and saved it to a viewstate variable. So when the user decides to send it, it sends that variable as the message to my emailer class. Its an internal app so the extra page weight shouldn't have to much impact on performace.
Its not perfect by any strech but It will work for now. I just find it hard to believe there isn't a function that allows you to capture the HTML from a local or remote website. If there is please let me know. I could have done this in Cold Fusion in 10 minutes or less.

Hey all -
so, does when does this control raise the ServerValidate event?
I have:
<asp:CustomValidator id="CustomValidator1" runat="server" ErrorMessage="David Custom Validation Bitatch" ControlToValidate="txtDate" Width="278px" Height="17px">
</asp:CustomValidator></P>
And I have:
private void CustomValidator1_ServerValidate(object source, System.Web.UI.WebControls.ServerValidateEventArgs args){
/* validate */}
It all works, I just can't figure out how the event is raised. Thanks much,

I have a DataGrid that will always spit out one row of data.But that row has about 50 columns or so.
Could somebody tell me how can i get a landscape view of this datagrid (ie invert the datagrid) so that the data that i want is clearly presented in my page??

I don't think there is built-in support for that, so you might have to build your own DataGrid control by deriving a class from .NET's DataGrid

I have built an alphabetical list of items in a database for a web page but for each letter of the alphabet I have to open and close the connection.
It seems there should be a more efficient method to accomplish this. (There are too many items in the database(s) to list them all together. It makes the page very tiresome to read and scroll through.)
Does anyone have any ideas that may help? I am new to ASP so I may have overlooked something obvious.

Sounds vague - are they not all in one table? Querying with the 'order by' would solve that immediately.
You could also populate a sorted collection with the resultsets and it would automatically do the sorting for you. I know in java there is a Treeset, I'm sure there is an equivalent in .NET...

I've been hearing a lot of buzz lately about the XQuery language, and how it's supposed to be the next "Big" thing. My question is why? Why learn yet another XML language that, from what I've seen of it, is just as cryptic as XSL, when I can quickly import XML to a .NET DataSet, and run SQL query's against it? It seems to me that XQuery is just going to be one of those buzz words that non-technical people look for when posting technical job requirements.

Couple of reasons.
You may not want the overhead of having to use a DataSet and the whole SQL parser.
The DataSet is not a public standard as such, so using it locks you down to MS. XQuery at least is an open, public standard.
XQuery is wonderfully suited to XML, as it should be. You can do things with XQuery to an XML file that you cannot do through a DataSet and SQL.
How many versions of SQL do we now have? Quite a lot with each having it's own idiosyncracies. XQuery is a strict standard.
XQuery can be run on the client side with compliant browsers. Can't do that with SQL.
And many more.
Really you should not be comparing XQuery and SQL. They are different tools for different jobs.
And yes, it is a big buzzword, just as XML is. But at the same time it is a lovely query language to work with IMO.

| Hey, thanks for the reply, Paul. 2 points that you mentioned sealed the deal for me to learn it: 1. The DataSet is not a public standard as such, so using it locks you down to MS. XQuery at least is an open, public standard.
2. XQuery can be run on the client side with compliant browsers. Can't do that with SQL. As for the DataSet being tied down to Microsoft, that should hopefully change soon with MONO. Of course, from what I've seen of it thus far, MONO still has a ways to go before completion.Again, thanks for the pointers.

I am attempting this function:
IF tellere = "1" AND modelID <> "%HT" THEN mIDe2="error"
I assumed that the "%" would act as a wild card, allowing me to take what the user inputs, look to see if it ends in "HT" and if it does, OK, and if it doesn't, return an error. I was wrong, the "%" doesn't work as a wildcard here. How would I accomplish this?

I think you are confusing SQL with ASP. As far as I know there is no wildcard for IF statements in ASP.
So in SQL you could do: SELECT * FROM [table] WHERE tellere = 1 AND modelID <> '%HT'
What you could do in ASP though is to use the INSTR func to return whether the specified string is in the var.

Using the history object, I can navigate "back" and "forwards". BUT what I'd like to do is just to find the URL of a page in the history and NOT navigate to it. Is it possible please?

This violates security policies set by JavaScript. NS will let you have it; however, if requested. With IE, AFAIK you're out of luck when getting URLs more than one deep unless you invisibly track this with fames or something.
In NS...
<script>
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
history.previous[1];
history.previous[2];
...
</script>BTW, you better not use this info for anything malicious!

I am developing a Web Image Viewer so that our customers can view images that we have scanned for them from anywhere.
I am trying to access the image (jpeg) files that are stored on another machine on the network from my ISAPI extension but I cannot.
I have shared the Image folder, giving permissions to everyone, and have mapped a drive letter to it on the local machine, so the path to the Images looks like:
V:\Images\Archived\fiename.jpg
I have trapped the System error message, using FormatMessage( )and get "Access Denied".
If I have the Images on the same machine as the Web Server, it works OK e.g. D:\Images\Archived\filename.jpg
Any ideas??? Any help would be greatly appreciated.
Many thanx.

Hi,
I'm writing a ISAPI program for a company project. The project requires that I don't use a database to save the user input. Instead I want to write the user data into a disk file on the server using CFile, is this possible?? I tried using CFile and writing it into a directory on the server that has write permissions, however all I get is a Exception in filecore.h.
Thanks for your help!!

Hello,
I have a rather nasty problem. I have an aspx page. This page loads an web user control using LoadControl. The control that is loaded also does a loadcontrol to load another control. And then this Control does again a loadcontrol. The Controls contain tables. By using findcontrol I can find the right tablecell to add the control to. On of the controls that is loaded by antoher control contains a checkbox, and when this one gets loaded I get an error saying that I must have a form with runat-server attribute. This is ofcourse present in the aspx page that starts all the dynamic loading.
so, summarized:
I have ControlA, ControlB, and ControlC
My aspx page loads ControlA, ControlA then loads ControlB and finds the right cell to add to the control colletion of that cell. Then ControlB loads ControlC and does also a findControl, but since ControlC has a <asp:checkbox runat="server"/"> the error "Control '_ctl0__ctl0__ctl1__ctl0' of type 'CheckBox' must be placed inside a form tag with runat=server. " occurs.
Is there a solution to this problem?
grtz

This is not really a strictly topical question, but this seemed the most appropriate forum to use.
I need a regular expression that would fail if a string:
a) contains white space
b) contains any non-textual character or 0-9 (i.e. not a-b, ê..., etc)
I have figured it out for white space, 0-9, and a-b, but cannot for the life of me figure out the last part. I have read more documentation than most people read books in a month and I just don't get it. How? 
Is the only way to use a really long [abcde....êçå...]?

Can't you simply do the following?
[a-zA-Z\xC1-\x259]+ , or whatever range you need? I'm not sure I'm understand the question entirely, but I think this is how you'd do it. Don't know what Regular Expression parser you're using, but Javascript only supports the standard ASCII set (0x00 - 0xFF).
Hope this helped.

I am currently trying to develop the website design area of my own company. In order to be able to do this realistically I need some good reference sites.
With this in mind I am currently offering a limited time, free web site design service. Go to http://www.salamandersoftware.biz/services/freeweb.htm and fill in the form or send an email detailing your requirements to freeweb@salamandersoftware.biz.
The offer will probably be open for a week or two and I will then review the submissions and choose probably four or five sites to develop. I'm looking for a good mixture, so low-graphics, database-driven, graphical UI, etc. Let me know what you're looking for (possibly with URL of sites you like the look-and-feel of) and I'll see what I can come with
This offer is limited to the initial web site design and implementation and does not include ongoing maintenance or re-design.
Submission of a design request does not guarantee acceptance under this offer, though all requests will be reviewed.
Derek Lakin.
I wish I was what I thought I was when I wished I was what I am.
