Hi,

Can anybody correct the below code. I am trying to restrict the numeric values in a string.

I am facing the following error "Incorrect syntax near '='".

I am new in VB .NET. Please help me to solve this.

VB.NET

If po_Country.cn_name = "" Then
            o_General.lp_AddPipe(ls_ErrMsg)
            ls_ErrMsg = ls_ErrMsg + "Country Name can not be empty."
        ElseIf po_Country.cn_name.Contains("0-9") Then
            o_General.lp_AddPipe(ls_ErrMsg)
            ls_ErrMsg = ls_ErrMsg + "Country name can not contain numeric values."
        End If

Regards,
Srikar

If you double click on the error in the Visual Studio error list, it will bring you to the exact line that is causing the error. Which of those lines is causing the error? Also, please format your code better. You can do that by selecting your code then clicking the "code block" button when you edit your question. Should look something like this:

VB

If po_Country.cn_name = "" Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country Name can not be empty."
ElseIf po_Country.cn_name.Contains("0-9") Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country name can not contain numeric values."
End If

I made it look like that by typing this:

<pre lang="vb">If po_Country.cn_name = "" Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country Name can not be empty."
ElseIf po_Country.cn_name.Contains("0-9") Then
    o_General.lp_AddPipe(ls_ErrMsg)
    ls_ErrMsg = ls_ErrMsg + "Country name can not contain numeric values."
End If</pre>

I could have done that for you, but I would rather teach you how to do it than do it for you.

Post the exact error message you are getting and the line of code that it occurs on, as well as the data type of each variable you are using.

Just a thought: perhaps you have not defined one of your variables as a string? Maybe you are attempting to do a string operation on a textbox or something.
