Failed To Convert Parameter Value From A String To A Int32?
Jan 12, 2010
I'm using a GridView control to edit data in a MySQL database.
I've created the C# code behind but I'm having trouble pulling back the parameter from a radiobutton control to populate an Int32 field in the database. I'm getting "Input string not in correct format"This is the particular bit (amongst a host of others of the same type) that is causing the problem:
I am not sure where my app is failing but most probably this is where it is failing.. I think lblExpID.Text is the culprit. Here's the relvant part of my code:
Dim lblExpID As Label For Each item In LSGrid.Rows lblExpID = item.FindControl("lblID") If txtExpGenFund.Text <> "" Then sqlArray(i) = ExpDetailsID & "," & (lblExpID.Text) & "," & MunID & "," & _ Val(txtExpGenFund.Text) & "," & Val(txtExpDetSpecialRevenue.Text) & "," & _ Val(txtExpDetCapitalProjects.Text) & "," & expTotal & "," & reportingYear & "," & "Test Comments" & "," & UserID End If
Can u help me identify why i am getting this error looking at the sp below:
PROCEDURE [dbo].[uspEXPENDITURE_DETAILS] ( @ExpDetailsID int=0 output, @ExpDet_ExpID int, @ExpDet_Municipality_ID nvarchar(50), @ExpDetGeneralFund money, @ExpDetSpecialRevenue money, @ExpDetCapitalProjects money, @ExpDetTotal money, @Exp_Reporting_Year varchar(10), @ExpComments varchar(max), @Contact_ID int ) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
delete from [dbo].[TBL_EXPENDITURE_DETAILS] where ExpDet_ExpID=@ExpDet_ExpID and ExpDet_Municipality_ID=@ExpDet_Municipality_ID and Exp_Reporting_Year=@Exp_Reporting_Year
If @ExpDetailsID >= 0 Begin INSERT INTO [dbo].[TBL_EXPENDITURE_DETAILS] ([ExpDet_ExpID] ,[ExpDet_Municipality_ID] ,[ExpDetGeneralFund] ,[ExpDetSpecialRevenue] ,[ExpDetCapitalProjects] ,[ExpDetTotal] ,[Exp_Reporting_Year] ,[ExpComments] ,[ExpDetCreatedBy] ,[ExpDetCreateDate]) VALUES (@ExpDet_ExpID, @ExpDet_Municipality_ID, @ExpDetGeneralFund, @ExpDetSpecialRevenue, @ExpDetCapitalProjects, @ExpDetTotal, @Exp_Reporting_Year, @ExpComments, @Contact_ID, GetDate() ) SET @ExpDetailsID = SCOPE_IDENTITY() return @ExpDetailsID end
I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.
When running our web application the following message appears:
Failed to convert parameter value string to decimal. We believe that the problem might be with the sequence which generates the user_id. The user_id should be the output after successful insert of record. The stored procedure works well from within the DB and Visual Studio. Our DB version: 11gR1 on Windows.The web form has a button event with this c#-code:
I have a problem while creating a web application using LinqTemplate here is the explanation step wise.... 1.I have created a database with a table name UserTest with one column name UserId with uniqidentifier datatype2. I have created a classLiberary Project where i have used LinqTemplate of subsonic for code Generation of DAL and created a partial class for UserTest
public partial class TestUser:Classes { public int Insert(TestUser user)
[code]...
Now when I Build the project it build successfully and when i run the project it shows the UserTest.aspx page with a button but when i click on button it must insert the new guid value into the table butit throws an exception
[InvalidCastException: Object must implement IConvertible.] System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) +2560525 System.Data.SqlClient.SqlParameter.CoerceValue(Object value, MetaType destinationType) +414 [InvalidCastException: Failed to convert parameter value from a Guid to a String.] TestPages.UserEdit.btnCreateNewAccount_Click(Object sender, EventArgs e) in D:TestPagesUserEdit.aspx.cs:61 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +105
and later using it as a parameter to the stored procedure.
The logic here is, the user should login first in order to retrieve his/her album. when the user is logged in, im retrieving the 'userid' and using it as parameter to load the corresponding album from the database.
when i login and open the albumpage, im end up with this exception:
"Failed to convert parameter value from a String to a Guid".
What could be the reason and how can i avoid this exception.
by the way im using the aspnet_Users table's userid field.
In timsplit i have value "17:00 - 2:00".Then i am converting it TimeIn and TimeOut.TimeIn is string now and how to convert it to int32.I am getting error while convertin Timesplit = strResultData.Split('-'); string TimeIn = Timesplit[0]; string TimeOut = Timesplit[1]; int TimeI = Int32.Parse(TimeIn);

Currently i using gridview to display a person informaton based on his login id however it show error because the session is set to ToString. Is it a way to convert the session to int32?
I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:

Here's my controller:

The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.
Sometimes Convert.ToInt32(object) will work and other times (Int32)object will work. How do you know which to use? I usually try one and if it doesn't work use the other but I'm sure that's not the best approach.
i work with visual studio 2005 and asp net 2.0. i have a method method as this :
[Code]....
this problem is follow if i run the web method and don't enter a string and a int a receive this message : System.ArgumentException: Cannot convert to System.Int32. ok when i arrive in the method i can check if lists is empty but how i can do if int is NULL because i don't want to returns a error if people run my web method and don't enter the parameters.
I am using Entity Framework to contact my data base. as part of my web code I am using Linq to entities, and I want to determine the number of elements in an anonymous type list. I can't get it to work, I get the exception: "LINQ to Entities does not recognize the method 'Int32 Parse(System.String)' method, and this method cannot be translated into a store expression."

I am writing unit tests for fluent Nhibernate, when I run the test in isloation it passes, but when I run multiple tests. or run the test more than once it starts failing with the message below System.ApplicationException : For property 'Id' expected '1' of type 'System.Int32' but got '2' of type 'System.Int32'
