How to pass the query string using hidden fields in vb.net...
View 3 RepliesRight now I am using this code on client side.
[Code]...
The values for the hidden fields are already set. I want these value to open a window, in which the fields will be already filled using the values passed by this page. This code is working fine on Internet Explorer, but not on other browsers. Moreover, when I don't pass any value and just open the required window, it works on all browsers.
Hi I've run into a really annoying problem, I'm trying to set the value of a hidden input to a comma seperated list taken from a database but in pure CSV format it won't set the value.The input tag and ul tag looks like this (I am aware of asp:hiddenfield and it's value property but I'm not using it as I still have this issue):
[code]...
This will populate the li tags but will not populate the value for the input, I've tried using the replace function on the list for the value but it only works if I remove the commas or put other characters infront of them. I've also tried replacing it with the HTML code for a comma but just prints the HTML code out.
This is probably embarrassingly easy, but I've having problems getting this to work.
On ResidentAddress.aspx, I have 2 user controls (AppName.ascx and NavButtons.ascx). When a textbox in AppName.ascx has focus, I want to update a hidden input field on NavButtons.ascx with the value of "TRUE". In the codebehind page for NavButtons, I want to see what the value of this hidden input filed is. [code]...
For some reason I have noticed that at run time when looking at my source of my ASP.NET page there are tags being created.
<input type="hidden" name="_VIEWSTATE" id="_viewstate" value="..lots of text.." />
and
<input type="hidden" name="_EVENTVALIDATION" id="_EVENTVALIDATION" value="..lots of text.."

I know that if you create a string like:dim a as string = "My String"if you open the compiled .exe in a hex editor you will see there "My String"now my question is about the Resources:if I add a string there, how easy would be for one to have access to it?Is it a plain xml that anyone could see or does it stay pretty hidden?

View 2 RepliesI am using visual studio 2010 to create a form where you can edit,delete, or insert data from an accessdatabase. When I try to run the form in a web browser I get the error "Query input must contain at least one table or query." I believe that the problem lies with my code/syntax but I am unable to determine the cause of the problem.
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="~/App_Data/database.accdb" SelectCommand="SELECT * FROM [database]"

I am able to add an existing MDF database to my project and apply it to a form with the appropriate binders and navigators and such and it works fine. I can hard code queries that are very successful. My question is this: Is there a way to add a textbox to the form, where I could enter a valid query that would execute on a button click event? It seems like I should be able to do so with SqlCommand, but I am just stumped.

I am receiving this error message: "Input string was not in a correct format." on my ASP.net 2.0 VB project.
When looking at other posts with this error its obvious that each time it will be specific to the users' project. Therefore my main question is, is it possible to generate a more informative error message?
I am already in debug mode but it does not tell me in which string the problem lies. I am converting some strings to integers with "Cint" and have also tried the Integer.Parse() method to no avail.
var queryString = string.Format("filename={0}&filestream={1}&append={2)", fileName, Convert.ToBase64String(b, 0, bytesRead).ToString(), 1);
above line of code giving error 'Input string was not in a correct format.'
I make a query in coding. But I got conversion error.My query is below
Dim strSelect As String = ""
strSelect = "SELECT " & _
"Description As [Desc], " & _

Exception error is like
Conversion from string "iif(CurCons = 0, " to type 'Double' is not valid
Actually, in my report, i wanna show if it's zero then '-'. If i set it in this string.I got another error like below The provider could not determine the Decimal value. For example, the row was just created, the default for the Decimal column was not available, and the consumer had not yet set a new Decimal value.

I am trying to write a program that reads values from a datafile and makes the data available in an array for further use in the program. The data consist of a description and then a value (COM_PORT=COM1, for example). My idea is to put the data in an array so that I can just search the array for COM_PORT and I will get COM1 back. Is that a good approach of handling it this way? What methods would I use to put the data (I use FileSystem.ReadAllText, the data is in a string) into an array? Would the split method work?

I'm having an issue with a page I created that was working fine two months ago. Nothing has changed in structure of the SQL tables and I have even done an insert within SQL to the table and all works fine with SQL. So the problem lies within the code. I'm getting this error:
Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.
Source Error:
Line 71: Dim sv As String = grd.Rows(i).Cells(7).Text

Line 75: PushIn002(sv.Remove(0, 6))

If I comment out line 73 and run it, I get the same error on 74. If I comment out 73, 74 and 75 the code runs to the end fine, it just doesn't insert the data into my table. It was working just fine and now it's not working.

My error message is as listed in the header "Input string was not in a correct format" however the stack trace is even more cryptic [code]...
This is worse due to the fact that nowhere in the project does it use "ParseDouble". I believe that this has something to do with the objectfactorylibrary but can't pin anything down.
