.net - Errors Say That An Expression Must Be Of CollectionType
Mar 15, 2012
The whole code here has to be used as a search engine. I need to build strings and then, convert them into queries. I had already done everything with linq-to-sql. But it seems impossible to convert a string into a linq querry. However, I found on stackoverflow a kind of solution, but I've never been able to use it : String.ToLinqQuery(). It's just not known by visual studio, and I can't find any documentation about it.
Although, here's the error I get :

there are a total of 5 errors with this code.
error 1: Optional parameters must specify a default value - error location "lastEl As object) As Long" - closing bracket is highlighted
Error 2: expression expected - error location "Optional lastEl As Variant) As Long" - where optional is highlighted.
Error 3: comma, ')', or a valid continuation expected - error location "strCycleIDarray As Variant" - where "as" is highlighted
Error 4: comma, ')', or a valid continuation expected - error location "strSearchCycleIDvalueArray As Variant" - where "as" is highlighted
Error 5: Ismissing is not declared and may not be accessible due to its protection level - error location "If IsMissing(lastEl) Then lastEl = UBound(strCycleIDarray)" - where "IsMissing" is Highlighted.
I dont have an idea where to start solving these errors and i cant debug this search as the errors are there.If you dont understand the errors in the format i have put them in just copy and paste the code into a windows form using a button as an activiator.

I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />
</customErrors>

While looking in the dataset designer for a database table I am doing in visual basic 2008 I found a line for expressions under the property menu for a specific column. I need to know the code that I would put in this expression line so that this column adds up the numbers I input into three other columns and displays that number in the column. I need it to automatically calculate this for each row in the database table.

I am using Flee to build a formula builder. It works great but the only problem I'm facing is that Flee doesn't understand Generic Methods I guess. I have a function called IIf declared in the expression context I'm using. [code]How can I work around this. I mean cannot , in sense, write all possible overloads of the function of all .net primitive types. What approach should I take.

I must convert string data from a CNC that is arithmetic expression to a number that I can use in a VB application that I wrote. The following is what I get out of the cnc. [18722*65536+19377]/67108864. I need to evaluate this expression in my VB ap. The format of the string is not always the same as what I have illustrated.

I am writing a app in VB and get errors with inserting or deleteing records. I can do a try catch in by app, but I would like to know how to make the cryptic error messages that I get back from my tableadapter queries into messages that make sense to the end user.

I am trying to deploy a ClickOnce app. It had worked previously when the server was just sitting with .Net 2.0 installed (no SP). Recently the server had 3.5SP1 installed on it and now ClickOnce is failing with the error:Value does not fall within the expected range inside System.Deployment.
Here is the information posted on the MSDN forums (answers there are generally hit or miss for me) with the call stack:It was in VS 2005 w/SP1 and I tried changing the path I publish to, changing the installation URL, changing the assembly name, manually controlling versions, running mage -cc, manually removing all application data in %userprofile%AppDataLocalApps and even changing deployment servers completely but still get the same error:
