Hey everyone,
recently I am workign on a project where people are able to search wines and later get them from my database. I store the variables from the search form in Session which i later retrieve in the next page (I couldnt use the query string here since its too small). However i get a problem in retrieving my data.
First of all my search field put the data to a session, here is the code.
public partial class catalogus : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void BTNzoeken_Click(object sender, EventArgs e)
{
Session["searchkleur"] = DDLkleur.SelectedValue;
Session["searchland"] = DDLland.SelectedValue;
Session["searchdruifsoort"] = TXTdruifsoort.Text;
Session["searchregio"] = DDLregio.SelectedValue;
Session["searchjaar"] = TXTjaar.Text;
Session["searchinhoud"] = DDLinhoud.SelectedValue;
Session["searchprijs"] = DDLprijs.SelectedValue;
Session["searchoverig"] = TXToverig.Text;
Session["searchwijnnaam"] = TXTwijnnaam.Text;
Session["searchproducent"] = TXTproducent.Text;
Response.Redirect("resultaten.aspx");
}
}
After this i will arrive at the resultaten.aspx page which holds the following code
public partial class resultaten : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Session["searchkleur"] != null)
{
string VARkleur = Session["searchkleur"].ToString();
string VARland = Session["searchland"].ToString();
System.Convert.ToInt32(VARland);
string VARdruifsoort = Session["searchdruifsoort"].ToString();
string VARregio = Session["searchregio"].ToString();
string VARjaar = Session["searchjaar"].ToString();
string VARinhoud = Session["searchinhoud"].ToString();
string VARprijs = Session["searchprijs"].ToString();
string VARoverig = Session["searchoverig"].ToString();
string VARwijnnaam = Session["searchwijnnaam"].ToString();
string VARproducent = Session["searchproducent"].ToString();
LBLtest.Text = "Kleur " + VARkleur + "<br />Land " + VARland + "<br />Druifsoort " + VARdruifsoort + "<br />Regio " + VARregio + "<br />Jaar " + VARjaar + "<br />Inhoud " + VARinhoud + "<br />Prijs " + VARprijs + "<br />Overig " + VARoverig + "<br />Wijnnaam " + VARwijnnaam + "<br />Producent " + VARproducent;
}
}
}
and here's my aspx part with the SQL command:
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ConnectionStrings:WijnhuisMDFConnectionString %>"
SelectCommand="SELECT [text] FROM [texten] WHERE textID = 26">
</asp:SqlDataSource>
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" BorderStyle="None"
DataSourceID="SqlDataSource2" GridLines="None" Width="240px">
<Columns>
<asp:BoundField DataField="text" HtmlEncode="False" SortExpression="text" />
</Columns>
</asp:GridView>
now i ve got 2 error messages: First one says that my landId cannot be converted to an integer so the session variable i stored as a string can't be converted to an int although i ve told C# to convert it.
2: i get an FormatException was unhandled y user code.
Does anyone know's whats wrong or how to solve it? I can share the project files if needed. Thanks in advance for your help

Ok, here is your problem I think.
string VARland = Session["searchland"].ToString();
System.Convert.ToInt32(VARland);
This means your VARland value is still stored in a string variable
try this
try
{
int32 VARland = System.Convert.ToInt32(Session["searchland"].ToString());
}
catch (Exception e)
{
....do something with your exception
}
I think your second error is because you have no try catch blocks and something is generating an exception
Hope this helps

Hi everyone!
I am experimenting with a rich text editor by using the contentEditable feature of HTML. I have the basic editor working, but I have run into a serious issue in FireFox. When you hit the return key, a second element of the same type is created...which is good. BUT If the element which was being typed in had an ID attribute, that ID gets duplicated into the new element. In fact, all attributes get duplicated into the new element.
Does anybody know how I can disable this default behavior? Or at least with regards to custom attributes?
If only there were some way to manually determine how elements are created...
Many thanks,
Lea Hayes

I have a working C# program. It's a gui that lets me access my parallel port. I would like to be able to convert it into a web page now. I've tried the copy past and start debugging approach. I think it's over my head.
I would like to know where to go or who to contact to have a pro work on it. I am willing to pay a programmer for a few hours of thier time. I will provide my working program and I can pay with paypal. Can someone please advise.

Hi All,
I have an ActiveX control hosted in a web page (<object> used). The problem is that when I scroll the page down or up the page is distorted by the control; seems a redraw issue in IE. Note that control is written in C++/ATL and uses double buffered OpenGL rendering. However, when I turn off double buffer feature from the control, the page is not getting distorted when it is being scrolled.
But I have to keep double buffering. So I think there should be some javascript magic to force the screen redraw (but not reload). So far I can handle window.scroll event, but I don't know which function will force the window to redraw itself.
If you could help I'd be very grateful.
Thanks!

Hi everyone,
I have some web services set up in IIS on Windows 2003 server. I am able to get to the test page by putting the servername in the URL but not if I use localhost. I have had the same problem with websites. Why would localhost not work? The ip address is listed correctly in the hosts file. The servers are always virtual machines (Virtual Server R2 or HyperV). Is there something different I have to do because it's a virtual machine?
Thanks for any ideas!

I have a gridview that row's cells contain textboxes. Currently, I highlite the row, in yellow using javascript, by changing the backgroundColor of each of the rows cell's textboxes. To set the backgroundColor I use the .childNode[0].style.backgroundColor = 'Yellow', see code below:
gridViewCtl.rows[index].cells[i].childNodes[0].style.backgroundColor = 'Yellow';
Now, I have a set of css files defined and would like to use a color defined in my css. Does anyone know how this can be done?
Thanks,
Steve

Specify a class in the css, and use the className attribute in Javascript to set the class of the rows or the class of an element containing the rows.

Hi you can make use of this piece of code
gridViewCtl.rows[index].cells[i].childNodes[0].className = 'your_class_name';
Hope this helps.
