C# - Cache Key Causes Error "Negating The Minimum Value Of A Twos Complement Number Is Invalid"?
Sep 1, 2010This is one of the strangest errors I've ever seen.
I'm doing a very simple call to return values from the HttpRuntime cache. The call is:
return HttpContext.Current.Cache[cacheKey];
If it returns null, that's fine. I check if the returned value is null and act accordingly. I've been using this call for a long time.
Recently, for some reason, when cacheKey is set to this exact value:
"Topic_GridSelectAll:5,null,2010-08-31-20-00-00,Published,desc,5,1"
a System.OverflowException is thrown: Negating the minimum value of a twos complement number is invalid.
Nothing about the call, associated code or server has changed. If the cacheKey has slightly different characters, it works perfectly fine. For instance, this cacheKey returns null without throwing any exception:
"Topic_GridSelectAll:5,null,2010-08-31-21-00-00,Published,desc,5,1"
Notice, the only difference between those two strings is the time characters: 2010-08-31-20-00-00 versus 2010-08-31-21-00-00.
Why the hell would that make any difference? And why now after all this time?
The stack trace is:
[OverflowException: Negating the minimum value of a twos complement number is invalid.]
System.Math.AbsHelper(Int32 value) +12753486
System.Web.Caching.CacheMultiple.UpdateCache(CacheKey cacheKey, CacheEntry newEntry, Boolean replace, CacheItemRemovedReason removedReason, Object& valueOld) +142
System.Web.Caching.CacheInternal.DoGet(Boolean isPublic, String key, CacheGetOptions getOptions) +122
MyProject.Helpers.CacheHelper.GetData(String cacheDomain, String cacheKey) in ...
I've tried changing the cache call to use HttpRuntime.Cache instead (ie. HttpRuntime.Cache[cacheKey]), but that made no difference. I know it's the same underlying cache provider, but I thought maybe the different call would make a difference.
Web Forms :: Minimum And Maimum RegularExpressionValidator
May 5, 2010gularExpressionValidator on my textbox that I am already using, but I need it tweaked. Here is the one I'm using: ^(([0-9]|[1][0-9]|2[0-3])(.)(25|50|75|00))|(24.00)|([0-9]|[1][0-9]|[2][0-4])$It is for the input of hours worked in a day. The minimum is 0.00 and the max is 24.00. The hours are rounded off to the quarter hour, so it allows for .25, .50, .75, and .00.

Web Forms :: Stretch Image In Panel Works, But In Table Needs Minimum Width?
Aug 10, 2010I have a panel where I have set a background image. (This image can stretch with the style I have declared) In this panel I have put a table with 3 Columns The table has width="100%" to be as wide as the panel. Each column has a label.
What I am trying to do is that Column 2 & 3 will have a static width and the Column 1 will have a dynamically width that can change if the browser window is adjusting its width.The problem in the code below is that the Column 2 & 3 width is getting smaller if the browser windows width is getting as small as possible. I am trying to have the width static all the way but in when the browserwindow get a very small width the columns
is getting small too.
Is it possible to set a minimum width to a <td> ?I have commented out the image to see more clear what happens. [Code]....

View 2 RepliesForms Data Controls :: When Casting From A Number, The Value Must Be A Number Less Than Infinity
Sep 30, 2010The following code gives error: "When casting from a number, the value must be a number less than infinity."
<asp:TemplateField HeaderText="DATE" SortExpression="date1">
<ItemTemplate>
<asp:Calendar ID="Calendar1" runat="server"
SelectedDate='<%# Bind("date1") %>' VisibleDate='<%# Eval("date1") %>'>

</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="Date1" runat="server" Text='<%# Bind("date1") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
The error occurs at the line <asp:Calendar ID="Calendar1"...>
It errors because there are records with null value for date1 when the records are returned from the database.
Is there a way to specify in the .aspx file telling it to ignore null or display null/blank?
Web Forms :: RequiredFieldValidator Not Working?
Mar 10, 2011I create a new website in VS 2010 (VB .Net). I add a table, within it i add a textbox, a button and a RequiedFieldValidator. I set the RFV ControlTValidate property to the textbox. When i move(click or tab) away from the textbox, the RFV doesnt kick in the error message that i have set.

ControlToValidate="txtEnterName" ErrorMessage="RequiredFieldValidator"
InitialValue="0" ForeColor="#FF3300"></asp:RequiredFieldValidator>

Oct 4, 2010I've recently finished building one of my first websites (and CMS) in ASP.NET but have came across a problem where a RequiredFieldValidator isn't working as it should do? I originally created the admin page to not require the RequiredFieldValidator, but now that I do need it the page won't acknowledge it's there. I have even set the field in the database to not accept nulls, but the query will still insert a null value into the database (SQL Server 2008 Express).
The TextBox that I'm referring to is "txtSectionTitle"

Web Forms :: RequiredFieldValidator Not Preventing Postback?
Oct 4, 2012I have this simple code:
<asp:Label ID="litInfo" runat="server" meta:resourceKey="litInfo" />
<br />
<asp:TextBox ID="txtEmail" runat="server" /><br />
[Code].....
I am expecting the RequiredFieldValidator control to prevent a postback when the textbox is filled in with an incorrect data and the button pressed. What happens is that the validator displays an error message but a postback is fired.
