Hi,
In my website i have a report where i have implemented try-catch
try
{
...
...
}
catch(Exception)
{
return;
}
but even on appling try-catch on every event my report sometimes gives error like "INPUT STRING IS NOT IN CORRECT FORMAT".
I have tried my best so that data type mismatch should not occur. This problem is significant with this report only.
Help me.
|
|
|
|

I guess the exception is catched within the report, so that your try-catch-statement will not be executed.
|
|
|
|
|
I cant understand what you mean by this.
If i am handling the exception before any function or data conversion executes then how this error can come.
|
|
|
|
|
Is an exception thrown? If not, how is the error displayed, within the report?
|
|
|
|
|
The error appears like this -->
Server Error in '/' Application.

What was the input string? Is there any special character on that string ?

Hi Abhijit,
Even on entering special charatcers , report is working fine. I cant fnd this error on local and only once on server but my clients have reported it many times. I am not undertaking any data conversions. I have text boxes for dates and i have tested it several times they are working fine. Even I cant understand why this error is coming as on local and even on server i cant find this error except only 1 time with all types of input.

Then why you are not asking client for data and tested with those data. I think there may be some script problem.

On this page i have only two textboxes for input that are used for entering dates. And i have tested it with every type of incorrect input. It is not giving any error.

The error it is giving is "Input String is not in Correct Format." to some of my clients. But i havn't received this error yet even on thorough testing of the page.

try to catch me if you can ![Jig | [Dance]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/jig.gif)
some one is eating the exception. If the exception is not re-thrown then there is nothing you can do.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Hiya everybody! I need some help trying to find out why is my WS not working as I want it to. I'm newbie when it comes to WebServices.
I got one that helps me get a DataSet so I can work with disconnected data.
public DataSet WSfnGetInfo(string strQuery, string strName, string strClientUser, string strClientPassword)
{
strUser = strClientUser;
strPassword = strClientPassword;
fnCreateCS();
SqlDataAdapter dAdapter = new SqlDataAdapter(strQuery, connString );
DataSet dsInfo = new DataSet();
dAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
try
{
dAdapter.Fill(dsInfo, strName);
}
catch(SqlException ex)
{
System.Web.HttpContext.Current.Response.Write(ex.Message);
return null;
}
return dsInfo;
}
Then I got my client WinApp in which I use this code to show the dataset on datagridview.
myServ.Service myService = new myServ.Service();
try
{
dsMeals = myService.WSfnGetInfo("SELECT * FROM dbo.MEALS", "MEALS", f1ref.user, f1ref.password);
dataGridView1.DataSource = dsMeals;
dataGridView1.DataMember = "MEALS";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + " " + ex.HelpLink + " " + ex.Data);
}
I can't get to show the data in datset in gridview. I get an error that the "Respons/Answer is not correct XML code". I'm stuck there.
From what I've read, returning DataSet from a WS ain't the best practice due nature of XML WSs and that it is too much text.
Any help is appreciated. 
I'm using this as a reference http://msdn.microsoft.com/en-us/library/s5xy331f(VS.80).aspx[^]

Hi All,
Do we have a inbuilt function in .Net or DotNetNuke to get the list of countries available. i need to fill it in a dropdown list and i need to avoid webservice which returns list of countries.
Thanks,
Maxy.

Any reason you can't just hard code it ? I mean, even if the list changes, if you won't call a webservice, it's a hard coded list you're expecting to end up with, right ?

there is no any function in asp.net,you have to search counry list from web, and store in your databse,from there you set datsource tool to fetch up in dropdown list.
i hope you wil satisfy my answer
thanking you

Damn - every time I think we've found the stupidest person, someone new comes up. You, sir, are scum. Buy the software, and once you do, please don't come here with your clueless questions, you're obviously too stupid to actually use Visual Studio.
