I was unable to read any Interger8 datatype in AD. For example, "lockoutTime" in User object in the Directory. I was just always got System.Runtime type and unable to cast to any other readable type.I was also using Active Directory Explorer to see this property in the AD. I saw the property schema is defined as "Integer8".Does anyone who know how to read this data out? I was trying a lot of time and still failed.
Now the above gives me error because the last parameter "outputMessage.FileByteStream.Length" returns a long type value but the method expects an integer type.
I have the following query in which I have to convert the 'bool' valu into 'string' value as "Y" or "N". I have a class defined called ChartDosCodeInfoStruct which definesQAIndicator as String. The value I am feteching from DB is a bool value. I need to take this bool value and accordingly assignQAIndicator= "Y" or "N".
I am using c# and socket programming to create a web application. Anyone knows how to declare a useable delegate or using another method to invoke or call a method such that my codes will not have error? I am stuck for at least a week!
If I'm returning an object, then it's pretty straight-forward. However, if I'm just trying to return whether or not the method was successful or not, what's the best option? Sure ... bool seems obvious - but what if you need to debug or get some additional details out of the method than just "yes/no"? Well that's where a string becomes more obvious, right? You can leave it empty to say that the method was successful or chock it full of details in the case of an error. But this can make it less intuitive to others who may have to run your functions and it also jumbles up everything you wanted to pass back into one large string.
Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<string>' to 'string' OK I am fairly new to LINQ, but I am starting to get the hang of it. So here is the of my code that bugs:

And it returns this error, on the second line for p:
Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<string>' to 'string'
I am new to asp .net and working on a already live project.When i am trying to run my application i am getting the following error:Explanation:The error occurred necessary for the processing of this demand while analysing the resource.

If I have below code, how to make it work as it has below compile error:
Error: cannot implicitly convert type 'System.Linq.Iqueryable<system.data.DataSet> to 'System.Data.Dateset'. An explicit conversion exists.
public DataSet GetProductList() { using (var sdatabase = new DatabaseDataContext()) { IQueryable<DataSet> result = wmsdatabase.ExecuteQuery<DataSet>(@"SELECT productid, productname from product group by productid, productname").AsQueryable(); return result; // Compile error here } }
I have a SQL which is running good at SQL Server Mgm studio:
"select d.EmployeeID, CONVERT(VARCHAR(10),d.LogTime,111) as Date1, MIN(CONVERT(VARCHAR(8), d.LogTime, 108)) as FirstIn from LogTable d where d.dwStatus=0 group by d.EmployeeID, CONVERT(VARCHAR(10), d.LogTime,111)"
However, When i put it into my code (Entity SQL):
"select d.EmployeeID, CONVERT(VARCHAR(10),d.LogTime,111) as Date1, MIN(CONVERT(VARCHAR(8), d.LogTime, 108)) as FirstIn from IGPSiteEntities.AccessLogSet AS d where d.dwStatus=0 group by d.EmployeeID, CONVERT(VARCHAR(10), d.LogTime,111)"
I got error :
'CONVERT' cannot be resolved into a valid type of function. Near simple identifier, line1, column 200.
LogTime is a DateTime format e.g 05/05/2010 14:12:12
I want to select ONLY the Date (e.g 05/05/2010) and select ONLY the time (e.g 14:12:12) so i use CONVERT function.
I am getting the same error (as this post: http://forums.asp.net/p/1346731/4020966.aspx) as expected class,delegate,enum,interface or struct and also type or namespace definition or end of file expected.Below is the code:
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
I am able to get a token with Windows Live Delegate Authentication samples provided by Microsoft.
Now I want to access emails (New, Read, Unread etc) from live account. How can I achieve it with the help of Windows Live Delegate Authentication? Are there any examples for the same?
The Samples given by Microsoft are not related to emails.
I have a gridview which I'm trying to get the display of phonenumbers listed in a certain display format; (xxx) xxx-xxxx.If I have the code such as this, it displays the unformatted phone number and (000) 000-0000 for the null items.
