I've just been asked to look after some classic asp code, currently running on IIS6, I'm on IIS7...and the existing code is throwing up a few errors I'm not sure I'd expect. Has anything changed in the way it should behave/is there a way to make it behave like it used to so I can fix these issues as it gets rebuilt?
The first is this:
If NOT ISNULL(fieldforfiltering) then
fieldforfiltering = TRIM(fieldforfiltering)
convertbackfield = Replace(fieldforfiltering, """, chr(34))
.....
End If
This is complaining that fieldforfiltering is null on the 3rd line. This I would expect from my C# life as the whole body of the if is not enclosed, so only the first line would get run (although there is an End If, so I'd sort of expect that to work...). However, it's working on IIS6, just not IIS7.
The second is a Cint issue
totcat = rs("totcat")
totalpage = totcat / 50
...throws a Type Mismatch error on the second line. If I change it to
totalpage = CInt(totcat) / 50
...it's fine. Again, I sort of know why - but why would that work on IIS6 and not IIS7?
I'd like to get it working as it is (as it clearly does work) and then go through and fix these over the coming months...it's too big a job to do it in one go.
It sounds like you might be running with different options: Option Strict On vs Option Strict Off, for example.

I've tried the simple program for my exercise but if i compiled, it turned give a message "No Way to get the console handle" (Dev-Pascal).
Here's my code:
program square;
uses crt;
var
side,circumference,broad:real;
begin
write('Input the side value of the square: ');
readln(side);
circumference := 4 * side;
broad := side * side;
writeln('The circumference value of the square = ', circumference);
writeln('The abroad value of the square = ', broad);
writeln();
write('Press any key...');
readkey();
end.
thank you for helping and teaching me
i would appreciate
Dev-pascal comes with a 10+ years old Free Pascal version. I really have no idea. Try to run the example on the cmdline to see if dev-pascal is the cause or something else. Temporarily disable security software might also be something to try.
I suppose, you've created a Window Skeleton project.
It has it's description: A Windows skeleton application (no window).
In this case you'll get this error though you code compiles (I've got this error too with your code).
Try to create Console Application project which has it's own description: A standard console-based (MS-DOS) application (Your code has compiled and the program worked as well).
P.S. Can't say what exactly happens -- couldn't find any documentation about errors in Dev-Pas (1.9.2).
My assumption is that skeleton program doesn't imply console window for execution program while console application does.
just close the project and then re-open the pascal source file (.pas). And maybe put "readln;" just before "END.".
An issue has been noticed on one of our old sites running 2.4 where when the user creates a link in the CMS content, selecting an existing page to link to, the link is not being converted to the actual URL on the front end and all links are coming through in the format of <a href="[sitetree_link_id=12]">
What would be causing this and how do I fix it?
The tag looks like it's being set incorrectly. It should be [sitetree_link id=12], not [sitetree_link_id=12].
We later added support to the parser for [sitetree_link,id=12] so that links didn't need to contain spaces, but I can't recall if that's in 2.4 or only 3.0+.
Can you confirm that your WYSIWYG insertion is putting in that errant _? If so, you might want to checkout the handleaction_insert function in tiny_mce_imporvements.js to confirm that it has a line like so:
case 'internal':
href = '[sitetree_link id=' + this.elements.internal.value + ']';
If the inserted links don't actually have the errant _ but they aren't being parsed, then try checking your sapphire/_config.php file for this:
ShortcodeParser::get('default')->register('sitetree_link', array('SiteTree', 'link_shortcode_handler'));
If your site makes changes to the ShortcodeParser at all you might have inadvertently turned off sitetree_link support.
If all of that looks in order, perhaps the ShortcodeParser isn't being called for some reason. In HTMLText::forTemplate(), put a debug statement (I like die("I got here!");) to confirm that HTMLText::forTemplate() is actually getting called. If it's not, you might need to manually call it in some pre-processing of your Content variable. Instead of this:
$content = $this->Content;
Do this:
$content = $this->obj('Content')->forTemplate();
I hope that one of those answers help. Either way, it would be great if you could post back, so we could isolate what caused this. It might help us make the API easier to use in SilverStripe 3.1.
I am very new to asp and having following problem
I am getting 2 values from 2 column, from database and when i try to multiply them, its giving following error
Error Type:
(0x80020009)
Exception occurred.
This is my code
totalPrice = totalPrice + rs("ProductQunaity") * rs("ProductPrice")
Even if someone can tell me what should be "Title" of this question, that would be great.
In case the error that amphetamachine pointed out is only in your code here at SO and not in the original code, please make sure that you don't have any type errors ( ;) ) with the values either.
totalPrice = totalPrice + CInt(rs("ProductQuantity")) * CDbl(rs("ProductPrice"))
where CInt() converts a value to an integer, and CDbl() converts a value to a double.
However, if you're very new to ASP, I'd recommend going straight to ASP.NET - ASP is a technology that hasn't developed in the last decade, while ASP.NET is Microsoft's new, fully supported (and pretty awesome) web development platform.
I'd recommend you start with ASP.NET MVC, since it is usually a lot cleaner, and it's straightforward to output the html you want. This and this are two good places to start.
Are you sure you typed that correctly?
# (what's this?) ---v
totalPrice = totalPrice + rs("ProductQunaity") * rs("ProductPrice"`)
Whenever you have errors like this, the best way to debug them is to response.write all the values out, then response.end before the line throwing the error is run. You can then inspect the values and attempt to work out why they are not compatible.
Usually using Visual Studio's debugger is a breeze. Scanning through Locals quickly shows the values of variables, etc. However, I'm at a loss how to find out the values contained in session state variables? Can anyone give me a hand?
Let's say I put a breakpoint right after:
Session["first_name"] = "Rob Roy";
How do I view the value contained in Session["first_name"] from locals?
It's pretty simple to inspect the session during debug. Just put a breakpoint in your code and just highlight your Session code (eg. highlight: Session["first_name"]) then right click and select QuickWatch....
This will setup up a watch on your Session for the value you had defined. You can also inspect other Session elements by adjusting the Expression field in the QuickWatch window and clicking the Reevaluate button.
In VS you can just put 'Session["first_name"]' in the Immediate Window and execute while the code is running. That will return the value that it holds.
If you can't find it go to: View > Other Windows > Command Window, or press Ctrl+W, A
It will look like this:
I know its a bit of a late reply but for anyone else who is interested, I hope this helps!
Isn't it HttpContext.Current.Session("..."), I ask as I haven't used ASP.NET for a long time.
I have a weird problem where the "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." error sometimes pops up when I am trying to build my project.
The line in question throwing the error was auto-generated code in the designer file for the dataset. To find out the offending table, I used the following code:
Try
Me.Adapter.Fill(dataTable) <--Breakpoint here on the offending line
Catch ex As Exception
For Each TRow As DataRow In dataTable.Rows
If TRow.HasErrors Then
Trace.Write(TRow.RowError)
End If
Next
End Try
Funnily enough, as soon as I run the project after putting in the above code and breakpoint, the error disappears. I assume this has something to do with the code being regenerated. All data is presented successfully, and the project compiles without errors.
However, this has happened often enough for me to frustrate me. Anybody know what might be causing the error and how I can isolate it?
What unique constraint are you placing on the datatable and have you verified that the data your passing in doesn't have any duplicates? If this is coming from a shared database perhaps someone else is modifying the data which could be causing the randomness.
Edit
If that code is exactly as what you have (And forgive me my vb.net is not as strong as my C#). Wouldn't it swallow the exception? In C# we need to rethrow the error.
Add a Trace.Write() right before you go into your for loop.
You are probably working with a typed dataset, or have some code configuration on it. Also you might be reading from one table, and then adding data from another.
In any of those cases, you really want to look into any inconsistencies between the schema. If it is a typed dataset / or configured in code, check its definition, and look for anything different from the sql table. If you are reading from 2 different tables, check the definition of both tables.
Figured it out finally!
The reason the breakpoint wasn't being hit was because the code in question was auto-generated, and had the attribute "DebuggerNonUserCodeAttribute". In addition, in my VS settings, I had set the debugger to "Just my code".
When I ran the code again, and the breakpoint wasn't hit, I noticed the breakpoint icon had changed to a warning. Hovering showed this:
"The breakpoint will currently not be hit. Breakpoints cannot be set in a method or class with the 'DebuggerNonUserCode' attribute when the debugger option 'Just My Code' is enabled."
Ouch!
Once I had removed the "Just My Code" debugging option, the breakpoint was hit, and I discovered that one of the rows had a NULL value in one of the columns which had a non-null constraint. Stupid ole' me!
You should use this code before you fill DataTable :
var dt = new System.DataTable.DataTable();
dt.Clear();
dt.Rows.Clear();
dt.Columns.Clear();
